Home versus center based physical activity programs in older adults

Linkages between incarceration and health for older adults

The aging population in United States (US) correctional facilities has grown dramatically over the last several decades. At present, roughly one in four adults incarcerated in US prisons are at least 50 years of age. Research over the last ten years has likewise expanded to catalog the impacts of incarceration on older adults, and the myriad ways incarceration is unique for this population. In this paper, we summarize the state of the literature at the intersection of incarceration, health, and aging. We begin by outlining the impacts of incarceration on a range of individual health outcomes for older adults. Next, we offer targeted policy implications to address the health consequences of incarceration for older adults. Finally, we conclude by offering a research agenda that emphasizes theory building, jail-based approaches, and expansion of what is known about older women, cognitive impairment, correctional staff perspectives, and interventions to enhance the health of older persons who are incarcerated.

How Do Physical Therapists and Athletic Trainers Maintain Their Physical Fitness? A Descriptive Survey Study

Background

Physical therapists and athletic trainers play an important role in promoting physical activity to patients and may utilize the 2018 United States Physical Activity Guidelines (PAG). Currently, there is little data regarding how physical therapists and athletic trainers maintain their personal fitness based upon these guidelines.

Purpose

To analyze how physical therapists and athletic trainers maintain their physical fitness based upon the 2018 United States Physical Activity Guidelines.

Study Design

Cross-sectional descriptive survey.

Methods

A 20-question electronic survey was emailed to members of the Academy of Orthopedic Physical Therapy and National Athletic Trainers Association. Professionals were also informed through a recruitment post in different private healthcare Facebook® groups. Survey inclusion criteria included respondents being a physical therapist or athletic trainer and being in clinical practice. Respondents were excluded if they did not meet the inclusions. The 2018 PAG were used as a minimum standard comparison for respondents to report their physical activity. The survey was developed using Qualtrics and underwent two rounds of pilot testing to establish face validity. The survey covered respondent demographics, exercise behaviors, reasons for exercise, exercise programming and assessment, exercise barriers, monitoring health & wellness, and respondent satisfaction with how they have maintained their own physical fitness. Descriptive statistics were used to calculate total responses, frequency count, and percentages.

Results

One thousand one hundred and forty seven professionals (Women =58%, N= 665; Men = 41%, N=472; other = 1%, N=10) (mean age = 48 ± 15.75 years-old) completed the survey. Most respondents (~ 82%) reported meeting or exceeding the PAG for aerobic and muscle-strengthening while using an integrated exercise approach with self-guided workouts (73%) in different settings such as home (65%) or fitness facility (30%). Respondents dedicated an average of 14 hours per week to exercise. A smaller portion of respondents did not meet the PAG and reported displeasure with their current fitness program which may be related to different exercise barriers such as work schedule, lack of time, family commitments, low intrinsic motivation, and lack of energy.

Conclusion

These survey results provide insight into how physical therapists and athletic trainers maintain their physical fitness. The majority of respondents demonstrated good exercise behaviors by exceeding or meeting the 2018 PAG while a smaller portion did not meet the guidelines due to various exercise barriers and displeasure. Future research should investigate strategies to help professionals find optimal work-life balance and time for weekly physical activity.

Home-Based, Low-Intensity, Gamification-Based, Interactive Physical-Cognitive Training for Older Adults Using the ADDIE Model: Design, Development, and Evaluation of User Experience

Background

Declines in physical and cognitive function are natural biological processes, leading to an increased risk of falls. Promising evidence suggests that combined physical-cognitive exercise has beneficial effects in improving both physical and cognitive health. Although moderate-to-high exercise intensity is commonly recommended, it might be impractical for older adults facing physical limitations or contraindications. Thus, low-intensity exercise is a viable option. The main barriers to engaging in exercise in older adults include transportation, time, motivation, and enjoyment. To overcome these challenges, a home-based, gamification-based training system may provide an effective approach to enhance exercise adherence.

Objective

This study aimed to develop and evaluate the usability of a low-intensity, gamification-based, interactive physical-cognitive exercise for older adults in a home-based setting.

Methods

The prototype of a game-based physical-cognitive exercise was created following the ADDIE model (analysis, design, development, implementation, and evaluation) and assessed for user experience in older adults. A total of 15 older adults engaged in the game-based physical-cognitive exercise at home for 60 minutes per day, 3 days per week, for 4 weeks. The usability of the game-based training system was evaluated using the system usability scale (SUS) after completion of a 4-week training program. As for satisfaction, the 8-item Physical Activity Enjoyment Scale (PACES) questionnaire was used to assess participants' enjoyment level after 1 week and 4 weeks of training. Descriptive statistics were used to illustrate the SUS score. A Wilcoxon signed-rank test was used to compare the PACES scores between the first week and the end of the 4-week period, with significance set at P<.05.

Results

As for experts' consensus, the game-based training consisted of 3 games: Ocean Diver, Road Runner, and Moving and Memorizing. The games had 3 levels of difficulty: beginner, intermediate, and advanced. A computer vision-based system was selected as the delivery platform for a home setting. The total SUS score for all participants was mean 87.22 (SD 5.76), indicating the user's perception of the usability of a system ranging from good to excellent. At the end of the 4-week training, the total PACES score was significantly greater than the first week, suggesting an improvement in enjoyment (first week: mean 44.93, SD 3.99 vs fourth week: mean 50.53, SD 4.70; P=.001).

Conclusions

The prototype of low-intensity, gamification-based, interactive physical-cognitive training was designed and developed using the ADDIE model, which included both experts and end users in the process. The findings showed that the exergame prototype was a usable and practical approach for a home-based setting, enhancing older adults' enjoyment and motivation. Further research is warranted to determine the effectiveness of such gamification-based training in promoting physical and cognitive functions.

Efficacy of the Otago-Exercise-Programme to reduce falls in community-dwelling adults aged 65-80 when delivered as group or individual training: Non-inferiority-clinical-trial

BACKGROUND

The Otago Exercise Programme is an effective intervention for falls prevention. However, there is limited evidence in relation to studies that compare efficacy for falls prevention when delivered Otago Exercise Programme in a group or individual format in a primary care context.

OBJECTIVE

To compare the Otago Exercise Programme delivered as a group vs. individual format for community dwelling older adults, over a one year period. The hypothesis was that neither format would be inferior to the other.

METHODS

DESIGN: A four-year multicentre, randomized, non-inferiority clinical trial, with two arms- Otago Exercise Programme group training and individual Otago exercise training.

SETTING(S)

21 primary healthcare centers.

PARTICIPANTS

A sample size of 728 participants was established. Participants were aged between 65 and 80 years; living in the community; able to walk independently; and agreed to take part in the study and provided signed informed consent.

INTERVENTION

The Otago Exercise Programme was delivered mainly by nurses in primary care, with five face to face sessions, and a reinforcement 6 months later. Participants were encouraged to exercise at home between face to face sessions.

DATA COLLECTION

at baseline and after 6 and 12 months from October 2017 to 2020.

PRIMARY OUTCOME

people who reported at least one fall.

SECONDARY OUTCOMES

number of falls, cause of falls, consequences and assistance, adherence and satisfaction. Group allocation was blinded to the researchers involved in analysis. Reporting: Consolidated Standards of Reporting Trials recommendations for the Statement for Randomized Trials of Nonpharmacologic Treatments.

RESULTS

Eight hundred twenty-seven participants were randomized (226 were allocated in group training and 272 in individual training). The analysis of the proportion of people who reported at least one fall and number of falls showed no differences between individual and group training. Assessment of the equivalence between the interventions at 12 months showed that the confidence interval for the difference of people who reported at least one fall was found to be within the equivalence limit of 10% considered. However, in those participants with a previous history of falls, group format showed potentially greater benefit. The participants in individual training presented higher scores on the Exercise Adherence Rating Scale test. No differences were found in satisfaction between the groups.

CONCLUSIONS

The group Otago Exercise Programme is equivalent to individually delivered Otago Exercise Programme in terms of prevention of falls over a 12-month follow up. Adherence was higher in individual training.

IMPLICATIONS

Healthcare professionals could offer either Otago Exercise Programme format dependent on patient preference and be confident that that standardized intervention provides patient benefit.

Assessing the Feasibility and Acceptability of Smart Speakers in Behavioral Intervention Research With Older Adults: Mixed Methods Study

BACKGROUND

Smart speakers, such as Amazon's Echo and Google's Nest Home, combine natural language processing with a conversational interface to carry out everyday tasks, like playing music and finding information. Easy to use, they are embraced by older adults, including those with limited physical function, vision, or computer literacy. While smart speakers are increasingly used for research purposes (eg, implementing interventions and automatically recording selected research data), information on the advantages and disadvantages of using these devices for studies related to health promotion programs is limited.

OBJECTIVE

This study evaluates the feasibility and acceptability of using smart speakers to deliver a physical activity (PA) program designed to help older adults enhance their physical well-being.

METHODS

Community-dwelling older adults (n=18) were asked to use a custom smart speaker app to participate in an evidence-based, low-impact PA program for 10 weeks. Collected data, including measures of technology acceptance, interviews, field notes, and device logs, were analyzed using a concurrent mixed analysis approach. Technology acceptance measures were evaluated using time series ANOVAs to examine acceptability, appropriateness, feasibility, and intention to adopt smart speaker technology. Device logs provided evidence of interaction with and adoption of the device and the intervention. Interviews and field notes were thematically coded to triangulate the quantitative measures and further expand on factors relating to intervention fidelity.

RESULTS

Smart speakers were found to be acceptable for administering a PA program, as participants reported that the devices were highly usable (mean 5.02, SE 0.38) and had strong intentions to continue their use (mean 5.90, SE 0.39). Factors such as the voice-user interface and engagement with the device on everyday tasks were identified as meaningful to acceptability. The feasibility of the devices for research activity, however, was mixed. Despite the participants rating the smart speakers as easy to use (mean 5.55, SE 1.16), functional and technical factors, such as Wi-Fi connectivity and appropriate command phrasing, required the provision of additional support resources to participants and potentially impaired intervention fidelity.

CONCLUSIONS

Smart speakers present an acceptable and appropriate behavioral intervention technology for PA programs directed at older adults but entail additional requirements for resource planning, technical support, and troubleshooting to ensure their feasibility for the research context and for fidelity of the intervention.

Stepping towards health: a scoping review of square-stepping exercise protocols and outcomes in older adults

BACKGROUND

Square-Stepping Exercise (SSE) is a type of physical-cognitive exercise. Such exercise has been used as an exercise approach in different studies with older adults. This scoping review provides an overview of the protocols and outcomes of studies employing the SSE in older adults.

METHODS

We searched in the PubMed, CINAHL, Scopus, CABI Global Health, and Web of Science databases for articles published between 2006 (first research article published on SSE) to December 2023 that met a robust inclusion criterion. The search yielded 424 articles, and after inclusion criteria being applied, 37 articles were included in the final analysis.

RESULTS

A total of 37 studies were included in the final analysis. Thirty-three out of the 37 studies focused on apparently healthy older adults, while four were conducted with older adults with neurological disease (i.e., multiple sclerosis, Parkinson's disease, and stroke). Most studies (n = 25) adopted an experiment (i.e., randomized controlled trial) or quasi-experimental approach, while 12 were classified as non-randomized (i.e., cross-sectional, mixed methods). The studies were conducted in different parts of the globe and adopted three major formats of intervention delivery, namely in-person, online, and home-based. Frequency, SSE session duration and intervention length significantly varied among studies, and reported outcomes were in the domains of physical and cognitive function.

CONCLUSION

This review comprehensively described the characteristics of 37 studies employing SSE in apparently healthy older adults and older adults with neurological diseases. The findings demonstrated that SSE has been used by researchers across the globe, adopting a variety of forms of delivery, and to particularly improve physical and cognitive function of different segments of the older adult population. The review further identified important gaps in research, including the restricted outcomes, and the lack of studies combining SSE with more traditional exercise modalities to address potential combinatory effects.

A 12-week multicomponent exercise program enhances frailty by increasing robustness, improves physical performance, and preserves muscle mass in older adults with HIV: MOVIhNG study

Background

Our aim was to analyze the effects of a multicomponent exercise program (MEP) on frailty and physical performance in older adults with HIV (OAWH) since exercise can reverse frailty in the older population overall, but there is no data for OAWH.

Methods

A prospective longitudinal study with intervention and control group was designed. Sedentary adults 50 or over with and without HIV were included. The intervention was a 12-week home-based MEP. Dependent variables were frailty (frailty phenotype), physical performance (Senior Fitness Test), muscle mass (ASMI) by bioimpedance. Pre- and postintervention measurements were analyzed using McNemar's test for categorical variables and the Wilcoxon signed-rank test for quantitative variables.

Results

40 OAWH and 20 OA without HIV. The median age was 56.5 years. 23.3% were women. The prevalence of frailty was 6.6% with no frail HIV-negative participants. Three of the four frail HIV-participants transitioned two (50%) from frail to prefrail and one (25%) to robust after the MEP. In participants with an adherence ≥50%, physical performance was significantly improved [basal vs. 12 week]: upper extremity strength [13 (13-15) vs. 16 (15-19), p = 0.0001], lower extremity strength [13 (11-16) vs. 15 (13-16), p = 0.004], aerobic endurance [62 (55-71) vs. 66 (58-80), p = 0.005]. Participants with low adherence experienced a significant worsening in ASMI [8.35 (7.44-9.26) vs. 7.09 (6.08-8.62), p = 0.03].

Conclusion

A 12-week MEP enhances frailty by increasing robustness in OAWH, and improves physical performance, and preserves muscle mass in older adults with good adherence to the MEP independently of HIV status.

Effects of home-based interventions using exergames on physical and cognitive functions in community-dwelling older adults: a PRISMA-P-compliant protocol for a systematic review

Introduction

Physical activity and exercise are crucial to counteract physical and cognitive decline in old age. Home-based exergame training can be a solution to overcome physical inactivity. This systematic review aims to provide a comprehensive overview of home-based exergame interventions and evaluate their effectiveness in improving cognitive and physical functions through physical activity enhancement in older adults.

Methods and analysis

We are conducting a systematic literature search including studies examining (1) community-dwelling older adults aged 60 years and older without any specific disease, (2) exergame-based exercise programs that take place at least partially in a home setting, and (3) intervention-related physical and/or cognitive outcomes. We will include randomized controlled trials and any other type of pre-post study published in English. There are no restrictions in terms of control group type and publication date. A search string was created and used in PubMed, Web of Science, Embase, Scopus and CINAHL. In addition, a hand search is carried out. This involves checking the references of the included studies and searching Google Scholar for further studies. The included studies will be summarized and, if homogeneity is sufficient, a random-effects meta-analysis will be performed. We will assess the risk of bias using RoB 2.0 and ROBINS-I.

Conclusion

The findings of this systematic review will help to define the most suitable exergame programs to counteract cognitive and physical decline in older adults. Additionally, they will inform the development of effective home-based exergame systems and point to future pathways of digital rehabilitation in older adults.

Effect of a home-based isometric handgrip training programme on systolic blood pressure in adults: A randomised assessor-blinded trial

OBJECTIVES

To evaluate the effects of 20 weeks of home-based isometric handgrip training (IHT) compared with usual care on systolic blood pressure (SBP) in adults.

DESIGN AND PARTICIPANTS

This was a randomised, controlled, assessor-blinded trial. Participants were randomised to either IHT (intervention group) or usual care (control group).

INTERVENTIONS

Participants randomised to the intervention group performed a session of 16 min of effective workout home-based IHT three times per week for 20 weeks. Participants randomised to the control group were asked to continue their daily activities as usual.

OUTCOMES

The primary outcome was the difference in SBP between groups over 20 weeks. Secondary outcomes were diastolic blood pressure, heart rate, handgrip strength, and self-administered home blood pressure measures.

RESULTS

Forty-eight adults (mean [SD] age, 64 [8] years) were included in this trial. The adjusted between-group mean difference in SBP was 8.12 mmHg (95% CI 0.24 to 16.01, p = 0.04) - favouring the usual care group. No differences between groups were found in any of the home blood pressure measurements.

CONCLUSIONS

This trial showed that 20 weeks of home-based isometric handgrip training was not superior compared to the usual care in lowering SBP.

The value of perioperative physical activity in older patients undergoing surgery for lung cancer

INTRODUCTION

With a median age at diagnosis of 70, lung cancer represents an enormous public health problem among older Americans. An estimated 19,000 people age 65 and older undergo lung cancer surgery annually in the US. Older adults undergoing lung cancer surgery are often frail with limited physiologic reserves, multi-morbidities, and functional impairments. Physical function, dyspnea, and quality of life return to baseline slower in older adults compared with younger adults after lung surgery.

AREAS COVERED

In this review, we summarize available data about perioperative physical activity interventions that may improve outcomes for older adults undergoing lung cancer surgery. We also review the limitations of existing studies and discuss emerging data on the roles of telehealth and family caregiver inclusion in peri-operative physical activity interventions.

EXPERT OPINION

We propose that future perioperative physical activity interventions in older adults undergoing lung cancer surgery should include a comprehensive geriatric assessment to guide personalized interventions. Interventions should be conceptually based, with a focus on enhancing self-efficacy, motivation, and adherence through classic behavior change strategies that are proven to impact outcomes. Finally, interventions should be designed with attention to feasibility and scalability. Exercise programs delivered via telehealth (telephone or tele-video) may improve access and convenience for patients.

Barriers and facilitators to participation in exercise prehabilitation before cancer surgery for older adults with frailty: a qualitative study

BACKGROUND

Older adults with frailty are at an increased risk of adverse outcomes after surgery. Exercise before surgery (exercise prehabilitation) may reduce adverse events and improve recovery after surgery. However, adherence with exercise therapy is often low, especially in older populations. The purpose of this study was to qualitatively assess the barriers and facilitators to participating in exercise prehabilitation from the perspective of older people with frailty participating in the intervention arm of a randomized trial.

METHODS

This was a research ethics approved, nested descriptive qualitative study within a randomized controlled trial of home-based exercise prehabilitation vs. standard care with older patients (≥ 60 years) having elective cancer surgery, and who were living with frailty (Clinical Frailty Scale ≥ 4). The intervention was a home-based prehabilitation program for at least 3 weeks before surgery that involved aerobic activity, strength and stretching, and nutritional advice. After completing the prehabilitation program, participants were asked to partake in a semi-structured interview informed by the Theoretical Domains Framework (TDF). Qualitative analysis was guided by the TDF.

RESULTS

Fifteen qualitative interviews were completed. Facilitators included: 1) the program being manageable and suitable to older adults with frailty, 2) adequate resources to support engagement, 3) support from others, 4) a sense of control, intrinsic value, noticing progress and improving health outcomes and 5) the program was enjoyable and facilitated by previous experience. Barriers included: 1) pre-existing conditions, fatigue and baseline fitness, 2) weather, and 3) guilt and frustration when unable to exercise. A need for individualization and variety was offered as a suggestion by participants and was therefore described as both a barrier and facilitator.

CONCLUSIONS

Home-based exercise prehabilitation is feasible and acceptable to older people with frailty preparing for cancer surgery. Participants identified that a home-based program was manageable, easy to follow with helpful resources, included valuable support from the research team, and they reported self-perceived health benefits and a sense of control over their health. Future studies and implementation should consider increased personalization based on health and fitness, psychosocial support and modifications to aerobic exercises in response to adverse weather conditions.

A feasibility study on home-based kyphosis-specific exercises on reducing thoracic hyperkyphosis in older adults

Objectives

This study aimed to assess the feasibility of the home-based kyphosis-specific exercises among Chinese older adults with different exercise habits and explore its potential effects on reducing the kyphosis angle and improving physical performance.

Methods

A single-group, pre-and post-test design was conducted according to CONSORT 2010 statement: extension for pilot and feasibility trials. A total of 20 participants aged ≥60 with thoracic hyperkyphosis and rehabilitation potential were recruited from four local communities in Wuhan, China. Participants underwent a six-week home-based kyphosis-specific exercises intervention that included warm-up, muscle strengthens, spinal alignment, spinal mobility and flexibility, and cool down five sections (22 exercises). The intervention involved seven 1-h group classes and 35 times daily home practice with identical content. At pre- and post-intervention, the participants' kyphosis angle in two standing postures, static balance, dynamic balance, cardiopulmonary function, dynamic gait assessment, pain, and self-image were assessed and compared. Feasibility was assessed by group class attendance, home practice adherence, and participant evaluations.

Results

All participants completed group classes and >75% home practice. Post-intervention, the participant's kyphosis angle in relaxed and best-standing postures was changed by -12.0° (-15.5°, -4.0°) (Z = - 3.98, P < 0.001）and -10.0° (-14.0°, -5.3°) (Z = -3.79, P < 0.001), respectively. In addition, participants had significantly less pain (P < 0.001), better self-image (P < 0.001), and improved performance in five physical assessments (P < 0.01). Different pre-intervention hyperkyphosis angle and daily physical activity did not affect intervention effects. Most participants considered the interventional exercise as moderate intensity and satisfactory.

Conclusions

Home-based kyphosis-specific exercises showed the possibility of being a feasible intervention. And it was advantageous to reducing the kyphosis angle and improving physical performance.

Health maintenance through home-based interventions for community-dwelling older people with sarcopenia during and after the COVID-19 pandemic: A systematic review and meta-analysis

BACKGROUND

The COVID-19 pandemic has greatly impacted people's lifestyles and changed the delivery of health interventions, especially interventions for community-dwelling older people with sarcopenia.

OBJECTIVE

To summarize the components and explore the effectiveness of home-based interventions for improving sarcopenia and other health-related outcomes among community-dwelling older people with sarcopenia.

DESIGN

Systematic review and meta-analysis.

METHODS

The Cochrane Library, Scopus, EMBASE, Web of Science, CINAHL, Medline (via PubMed), and PsycINFO were searched for relevant papers published from January 1, 2010 to March 29, 2022. Only papers written in English were included. The modified version of Cochrane's risk-of-bias tool was used to assess the risks of bias in the included studies. The template for intervention description and replication checklist was used to summarize the intervention components. The mean difference (MD) or standard mean difference with a 95 % confidence interval (CI) was used to determine the effect size of studies using the same or different measuring methods. Random-effects models were in meta-analyses to pool the effects of home-based interventions on the included outcomes.

RESULTS

After detailed screening and exclusion, 11 randomized controlled trials including 1136 older people with sarcopenia were included in our analyses. Three categories of home-based interventions were identified: exercise interventions, nutritional interventions, and combined exercise and nutritional interventions. The overall analysis of the outcomes (e.g., appendicular skeletal muscle mass index, lean mass, body fat mass, handgrip strength, and gait speed), showed that the effects of home-based exercise interventions were inconclusive. Compared with passive controls, home-based exercise interventions significantly improved knee extension strength (MD = 0.56 kg, 95 % CI: 0.09, 1.03, p = 0.020) and reduced the time required to complete the Timed Up and Go Test (MD = -1.41 s, 95 % CI: -2.28, -0.54, p = 0.001). Home-based nutritional interventions were effective in improving appendicular skeletal muscle mass (MD = 0.25 kg, 95 % CI: 0.02, 0.49, p = 0.030), gait speed (MD = 0.06 m/s, 95 % CI: 0.03, 0.09, p = 0.0001), and quality of life in terms of both the physical component summary (MD = 13.54, 95 % CI: 0.73, 26.34, p = 0.040) and mental component summary scores (MD = 8.69, 95 % CI: 2.98, 14.41, p = 0.003).

CONCLUSION

Home-based exercise interventions have the potential to improve muscle strength and physical function, while home-based nutritional interventions are effective in increasing muscle mass, physical function, and quality of life. Both of these can be applied at home during and after the COVID-19 pandemic to alleviate sarcopenia and improve health-related outcomes in community-dwelling older people.

Individualized Remotely Supervised Motor Activity Programs Promote Rehabilitation Goal Achievement, Motor Functioning, and Physical Activity of People with Rett Syndrome-A Single-Cohort Study

BACKGROUND

Gross motor function in Rett syndrome (RTT) is always limited. The complex clinical picture typical of most people with RTT requires intensive and specific rehabilitation programs. Previous reports on remotely supervised motor activity programs suggested positive outcomes for this population. The current article describes the impact of a remote-supervised motor activity program carried out by family members of individuals with RTT on achieving rehabilitation goals and improving gross and fine motor functioning and daily physical activity.

METHODS

Forty subjects with RTT followed a three-month remotely supervised motor activity program carried out by their family members at home after a three-month baseline period. After the end of the intervention, a three-month wash-out period was implemented. Rehabilitation goal achievement, motor functioning, and level of daily physical activity were measured.

RESULTS

82.4% of rehabilitation goals were achieved or overachieved. Participants' motor functioning and physical activity significantly increased after the intervention (p ˂ 0.001). Improvements were maintained after the wash-out phase.

CONCLUSIONS

The proposed intervention was effective for people with RTT of various ages and severity levels. The results highlight the need for lifelong, individualized, daily based, and professionally supervised rehabilitation possibilities for individuals with RTT.

Effectiveness of home-based exercise delivered by digital health in older adults: a systematic review and meta-analysis

BACKGROUND

regular physical exercise is essential to maintain or improve functional capacity in older adults. Multimorbidity, functional limitation, social barriers and currently, coronavirus disease of 2019, among others, have increased the need for home-based exercise (HBE) programmes and digital health interventions (DHI). Our objective was to evaluate the effectiveness of HBE programs delivered by DHI on physical function, health-related quality of life (HRQoL) improvement and falls reduction in older adults.

DESIGN

systematic review and meta-analysis.

PARTICIPANTS

community-dwelling older adults over 65 years.

INTERVENTION

exercises at home through DHI.

OUTCOMES MEASURES

physical function, HRQoL and falls.

RESULTS

twenty-six studies have met the inclusion criteria, including 5,133 participants (range age 69.5 ± 4.0-83.0 ± 6.7). The HBE programmes delivered with DHI improve muscular strength (five times sit-to-stand test, -0.56 s, 95% confidence interval, CI -1.00 to -0.11; P = 0.01), functional capacity (Barthel index, 5.01 points, 95% CI 0.24-9.79; P = 0.04) and HRQoL (SMD 0.18; 95% CI 0.05-0.30; P = 0.004); and reduce events of falls (odds ratio, OR 0.77, 95% CI 0.64-0.93; P = 0.008). In addition, in the subgroup analysis, older adults with diseases improve mobility (SMD -0.23; 95% CI -0.45 to -0.01; P = 0.04), and balance (SMD 0.28; 95% CI 0.09-0.48; P = 0.004).

CONCLUSION

the HBE programmes carried out by DHI improve physical function in terms of lower extremity strength and functional capacity. It also significantly reduces the number of falls and improves the HRQoL. In addition, in analysis of only older adults with diseases, it also improves the balance and mobility.

Machine learning-based classification of circadian rhythm characteristics for mild cognitive impairment in the elderly

Introduction

Using wrist-wearable sensors to ecological transient assessment may provide a more valid assessment of physical activity, sedentary time, sleep and circadian rhythm than self-reported questionnaires, but has not been used widely to study the association with mild cognitive impairment and their characteristics.

Methods

31 normal cognitive ability participants and 68 MCI participants were monitored with tri-axial accelerometer and nocturnal photo volumetric pulse wave signals for 14 days. Two machine learning algorithms: gradient boosting decision tree and eXtreme gradient boosting were constructed using data on daytime physical activity, sedentary time and nighttime physiological functions, including heart rate, heart rate variability, respiratory rate and oxygen saturation, combined with subjective scale features. The accuracy, precision, recall, F1 value, and AUC of the different models are compared, and the training and model effectiveness are validated by the subject-based leave-one-out method.

Results

The low physical activity state was higher in the MCI group than in the cognitively normal group between 8:00 and 11:00 (P < 0.05), the daily rhythm trend of the high physical activity state was generally lower in the MCI group than in the cognitively normal group (P < 0.05). The peak rhythms in the sedentary state appeared at 12:00-15:00 and 20:00. The peak rhythms of rMSSD, HRV high frequency output power, and HRV low frequency output power in the 6h HRV parameters at night in the MCI group disappeared at 3:00 a.m., and the amplitude of fluctuations decreased; the amplitude of fluctuations of LHratio nocturnal rhythm increased and the phase was disturbed; the oxygen saturation was between 90 and 95% and less than 90% were increased in all time periods (P < 0.05). The F1 value of the two machine learning algorithms for MCI classification of multi-feature data combined with subjective scales were XGBoost (78.02) and GBDT (84.04).

Conclusion

By collecting PSQI Scale data combined with circadian rhythm characteristics monitored by wrist-wearable sensors, we are able to construct XGBoost and GBDT machine learning models with good discrimination, thus providing an early warning solution for identifying family and community members with high risk of MCI.

Covid-19 Analysis: Is there an Association Between Covid-19 and Development of Cognitive Deficits?

OBJECTIVE

The effects of COVID-19 infection were initially thought to be limited to the respiratory system; however, recent literature suggests that the virus has systemic effects, even leading to cognitive deficits. The objective of this study is to review COVID-19 related literature to determine whether there is an association between COVID-19 infection and the development of cognitive deficits.

METHOD

A search for articles relevant to COVID-19, cognitive deficits, the Montreal Cognitive Assessment Tool (MoCA), and the geriatric population was performed on the MEDLINE, CINAHL, and APA PsychInfo databases.

RESULTS

Substantial evidence exists that reports an association between COVID-19 infection and cognitive decline. The studies included in this literature review surveyed distinct populations and reported cognitive deficits in COVID-19 patients as measured by a reduction in MoCA scores. While cognitive deficits were identified as partially reversible, there were still measurable deficits in cognition post-recovery compared to healthy controls. Furthermore, the measured cognitive deficits were found to be much worse in the geriatric population.

CONCLUSIONS

Current literature shows an association between COVID-19 infection and the development of cognitive deficits. Further research should seek to characterize these cognitive deficits and determine the underlying aetiology and pathogenesis. Initiatives to develop interventions to limit or improve cognitive deficits in post COVID-19 patients is crucial, especially the elderly, given the large burden of disease within this population cohort.

Mobility training for increasing mobility and functioning in older people with frailty

BACKGROUND

Frailty is common in older people and is characterised by decline across multiple body systems, causing decreased physiological reserve and increased vulnerability to adverse health outcomes. It is estimated that 21% of the community-dwelling population over 65 years are frail. Frailty is independently predictive of falls, worsening mobility, deteriorating functioning, impaired activities of daily living, and death. The World Health Organization's International Classification of Functioning, Disability and Health (ICF) defines mobility as: changing and maintaining a body position, walking, and moving. Common interventions used to increase mobility include functional exercises, such as sit-to-stand, walking, or stepping practice.

OBJECTIVES

To summarise the evidence for the benefits and safety of mobility training on overall functioning and mobility in frail older people living in the community.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, AMED, PEDro, US National Institutes of Health Ongoing Trials Register, and the World Health Organization International Clinical Trials Registry Platform (June 2021).

SELECTION CRITERIA

We included randomised controlled trials (RCTs) evaluating the effects of mobility training on mobility and function in frail people aged 65+ years living in the community. We defined community as those residing either at home or in places that do not provide rehabilitative services or residential health-related care, for example, retirement villages, sheltered housing, or hostels.  DATA COLLECTION AND ANALYSIS: We undertook an 'umbrella' comparison of all types of mobility training versus control.

MAIN RESULTS

This review included 12 RCTs, with 1317 participants, carried out in 9 countries. The median number of participants in the trials was 97. The mean age of the included participants was 82 years. The majority of trials had unclear or high risk of bias for one or more items. All trials compared mobility training with a control intervention (defined as one that is not thought to improve mobility, such as general health education, social visits, very gentle exercise, or "sham" exercise not expected to impact on mobility). High-certainty evidence showed that mobility training improves the level of mobility upon completion of the intervention period. The mean mobility score was 4.69 in the control group, and with mobility training, this score improved by 1.00 point (95% confidence interval (CI) 0.51 to 1.51) on the Short Physical Performance Battery (on a scale of 0 to 12; higher scores indicate better mobility levels) (12 studies, 1151 participants). This is a clinically significant change (minimum clinically important difference: 0.5 points; absolute improvement of 8% (4% higher to 13% higher); number needed to treat for an additional beneficial outcome (NNTB) 5 (95% CI 3.00 to 9.00)). This benefit was maintained at six months post-intervention. Moderate-certainty evidence (downgraded for inconsistency) showed that mobility training likely improves the level of functioning upon completion of the intervention. The mean function score was 86.1 in the control group, and with mobility training, this score improved by 8.58 points (95% CI 3.00 to 14.30) on the Barthel Index (on a scale of 0 to 100; higher scores indicate better functioning levels) (9 studies, 916 participants) (absolute improvement of 9% (3% higher to 14% higher)). This result did not reach clinical significance (9.8 points). This benefit did not appear to be maintained six months after the intervention. We are uncertain of the effect of mobility training on adverse events as we assessed the certainty of the evidence as very low (downgraded one level for imprecision and two levels for bias). The number of events was 771 per 1000 in the control group and 562 per 1000 in the group with mobility training (risk ratio (RR) 0.74, 95% CI 0.63 to 0.88; 2 studies, 225 participants) (absolute difference of 19% fewer (9% fewer to 26% fewer)). Mobility training may result in little to no difference in the number of people who are admitted to nursing care facilities at the end of the intervention period as the 95% confidence interval includes the possibility of both a reduced and increased number of admissions to nursing care facilities (low-certainty evidence, downgraded for imprecision and bias). The number of events was 248 per 1000 in the control group and 208 per 1000 in the group with mobility training (RR 0.84, 95% CI 0.53 to 1.34; 1 study, 241 participants) (absolute difference of 4% fewer (8% more to 12% fewer)). Mobility training may result in little to no difference in the number of people who fall as the 95% confidence interval includes the possibility of both a reduced and increased number of fallers (low-certainty evidence, downgraded for imprecision and study design limitations). The number of events was 573 per 1000 in the control group and 584 per 1000 in the group with mobility training (RR 1.02, 95% CI 0.87 to 1.20; 2 studies, 425 participants) (absolute improvement of 1% (12% more to 7% fewer)). Mobility training probably results in little to no difference in the death rate at the end of the intervention period as the 95% confidence interval includes the possibility of both a reduced and increased death rate (moderate-certainty evidence, downgraded for bias). The number of events was 51 per 1000 in the control group and 59 per 1000 in the group with mobility training (RR 1.16, 95% CI 0.64 to 2.10; 6 studies, 747 participants) (absolute improvement of 1% (6% more to 2% fewer)).

AUTHORS' CONCLUSIONS

The data in the review supports the use of mobility training for improving mobility in a frail community-dwelling older population. High-certainty evidence shows that compared to control, mobility training improves the level of mobility, and moderate-certainty evidence shows it may improve the level of functioning in frail community-dwelling older people. There is moderate-certainty evidence that the improvement in mobility continues six months post-intervention. Mobility training may make little to no difference to the number of people who fall or are admitted to nursing care facilities, or to the death rate. We are unsure of the effect on adverse events as the certainty of evidence was very low.

Determining thresholds for spatial urban design and transport features that support walking to create healthy and sustainable cities: findings from the IPEN Adult study

An essential characteristic of a healthy and sustainable city is a physically active population. Effective policies for healthy and sustainable cities require evidence-informed quantitative targets. We aimed to identify the minimum thresholds for urban design and transport features associated with two physical activity criteria: at least 80% probability of engaging in any walking for transport and WHO's target of at least 15% relative reduction in insufficient physical activity through walking. The International Physical Activity and the Environment Network Adult (known as IPEN) study (N=11 615; 14 cities across ten countries) provided data on local urban design and transport features linked to walking. Associations of these features with the probability of engaging in any walking for transport and sufficient physical activity (≥150 min/week) by walking were estimated, and thresholds associated with the physical activity criteria were determined. Curvilinear associations of population, street intersection, and public transport densities with walking were found. Neighbourhoods exceeding around 5700 people per km², 100 intersections per km², and 25 public transport stops per km² were associated with meeting one or both physical activity criteria. Shorter distances to the nearest park were associated with more physical activity. We use the results to suggest specific target values for each feature as benchmarks for progression towards creating healthy and sustainable cities.

Do Interventions Reducing Social Vulnerability Improve Health in Community Dwelling Older Adults? A Systematic Review

Background

Social vulnerability occurs when individuals have been relatively disadvantaged by the social determinants of health. Complex interventions that reduce social vulnerability have the potential to improve health in older adults but robust evidence is lacking.

Objective

To identify, appraise and synthesize evidence on the effectiveness of complex interventions targeting reduction in social vulnerability for improving health related outcomes (mortality, function, cognition, subjective health and healthcare use) in older adults living in the community.

Methods

A mixed methods systematic review was conducted. Five databases and targeted grey literature were searched for primary studies of all study types according to predetermined criteria. Data were extracted from each distinct intervention and quality was assessed using the Mixed Methods Appraisal Tool. Effectiveness data were synthesized using vote counting by direction of effect, combining p values and Albatross plots.

Results

Across 38 included studies, there were 34 distinct interventions categorized as strengthening social supports and communities, helping older adults and their caregivers navigate health and social services, enhancing neighbourhood and built environments, promoting education and providing economic stability. There was evidence to support positive influences on function, cognition, subjective health, and reduced hospital utilization. The evidence was mixed for non-hospital healthcare utilization and insufficient to determine effect on mortality.

Conclusion

Despite high heterogeneity and varying quality of studies, attention to reducing an older adult's social vulnerability assists in improving older adults' health.

Do Breast Cancer Patients Manage to Participate in an Outdoor, Tailored, Physical Activity Program during Adjuvant Breast Cancer Treatment, Independent of Health and Socio-Demographic Characteristics?

Exercise could reduce the side-effects of adjuvant breast cancer treatment; however, socio-demographic, health, and intervention conditions may affect patients' adherence to interventions. This study aimed to examine adherence to a 12-month outdoor post-surgery exercise program among newly diagnosed breast cancer patients during adjuvant treatment, and to identify socio-demographic and health-related predictors. In total, 47 women with invasive breast cancer stage I-II or ductal/lobular carcinoma grade 3 were included pre-surgery and randomized two weeks post-surgery to exercise (2 × 60 min/week). Patient characteristics (body-mass index (BMI), socioeconomic status, comorbidity, physical activity, and maximal oxygen uptake (VO2max)) were recorded pre-surgery. Correlations between adherence and patient characteristics and statistics for between-group differences were performed. The mean age was 54.2 years, mean BMI 27.8 kg/m2, and 54.2% received chemotherapy. Completers had a mean adherence of 81%, independent of season. Withdrawals (23%) occurred after a mean of 6.5 weeks (0-24 weeks), they were suggestively older, had lower socioeconomic status and pre-surgery VO2max, and higher BMI. Household income was significantly lower among withdrawals. There were insignificant correlations between adherence and health conditions. High adherence is achievable in a Nordic outdoor physical exercise program in breast cancer patients during adjuvant treatment, including chemotherapy. Additional studies are needed to clarify follow-up needs in some groups.

Potential value of home square-stepping exercises for inactive older adults: an exploratory case study

Background

Most older adults do not engage in regular physical activity. However, more research on options to partake in regular exercise in this population by reducing barriers and enhancing enablers while still reaching benefits is needed.

Methods

Using embedded mixed methods, 10 inactive older adults over the age of 65 completed a 3-week square-stepping exercise intervention to help overcome the initial barriers and activate initial enablers to perform regular exercise. Physical activity level was tracked at home with a pedometer using median steps/day over seven days for pre-post measure. Aerobic intensity while doing square-stepping exercises was quantified via a heart rate monitor in a supervised session. Each participant had an interview asking about barriers and enablers to regular exercise and if the intervention could modify any. Based on initial physical activity a framework matrix was used to pull potential barriers to compare, contrast, and search for patterns between participants with lower and higher initial physical activity levels.

Results

The 3-week square-stepping exercise intervention helped participants overcome barriers such as being uncomfortable in a fitness facility and body image and activate enablers such as the use of home equipment and convenience. The median total steps/day increased by 12% (p = 0.02), and a moderate-intensity level was reached by 80% of the sample participants when performing the square stepping exercise during a supervised session. Common barriers such as having a suitable program, hard to keep the intensity were reported by participants regardless of the initial physical activity level.

Conclusion

Regardless of initial physical activity level, inactive older adults can increase physical activity level at the recommended intensity and overcome common barriers to exercise when performing square-stepping exercises, especially for those intimidated by a fitness facility setting and those concerned with their body image. A longer intervention including more participants using the square-stepping exercises is required to understand if square-stepping exercises can increase the proportion of older adults exercising regularly.

Intervening on exercise and daylong movement for weight loss maintenance in older adults: A randomized, clinical trial

OBJECTIVE

This study aimed to determine the impact of dietary weight loss (WL) plus aerobic exercise (EX) and a "move more, more often" approach to activity promotion (SitLess; SL) on WL and maintenance.

METHODS

Low-active older adults (age 65-86 years) with obesity were randomized to WL+EX, WL+SL, or WL+EX+SL. Participants received a social-cognitive group-mediated behavioral WL program for 6 months, followed by a 12-month maintenance period. EX participants received guided walking exercise with the goal of walking 150 min/wk. SL attempted to achieve a step goal by moving frequently during the day. The primary outcome was body weight at 18 months, with secondary outcomes including weight regain from 6 to 18 months and objectively assessed physical activity and sedentary behavior at each time point.

RESULTS

All groups demonstrated significant WL over 6 months (p < 0.001), with no group differences. Groups that received SL improved total activity time (p ≤ 0.05), and those who received EX improved moderate-to-vigorous activity time (p = 0.003). Over the 12-month follow-up period, those who received WL+EX demonstrated greater weight regain (5.2 kg; 95% CI: 3.5-6.9) relative to WL+SL (2.4 kg; 95% CI: 0.8-4.0).

CONCLUSIONS

Pairing dietary WL with a recommendation to accumulate physical activity contributed to similar WL and less weight regain compared with traditional aerobic exercise.

The influence of a supervised group exercise intervention combined with active lifestyle recommendations on breast cancer survivors' health, physical functioning, and quality of life indices: study protocol for a randomized and controlled trial

Background

Most cancer patients, under active treatment or not, are sedentary, despite increasing scientific and clinical understanding of the benefits of exercise and physical activity, such as improving quality of life, limiting disease symptoms, decreasing cancer recurrence, and increasing overall survival. Studies have shown that both supervised exercise and unsupervised physical activity programs have low adherence and limited long-term benefits among cancer survivors. Therefore, interventions focused on increasing physical activity levels have clinical and psychological relevance. The present study will examine the feasibility and efficacy of an intervention that combines supervised group exercise with active lifestyle recommendations, analyzing its clinical, psychological, physiological, functional, and immunological effects in breast cancer survivors.

Methods

Women aged 35–75 years who have completed chemotherapy, radiotherapy, and surgery for breast cancer will be recruited from the Cancer Institute of the State of Sao Paulo (ICESP) and take part in a 16-week, parallel-group, randomized, and controlled trial. They will receive a booklet with recommendations for achieving a physically active lifestyle by increasing overall daily movement and undertaking at least 150 min/week of structured exercise. Then, they will be randomized into two groups: the supervised group will take part in two canoeing group exercise sessions every week, and the unsupervised group will increase their overall physical activity level by any means, such as active commuting, daily activities, or home-based exercise. Primary outcome includes aerobic capacity. Secondary outcomes are physical activity, physical functioning, self-reported quality of life, fatigue, presence of lymphedema, body composition, immune function, adherence to physical activity guidelines, and perceptions of self-image.

Discussion

Results should contribute to advance knowledge on the impact of a supervised group exercise intervention to improve aspects related to health, physical functioning, and quality of life in female breast cancer survivors.

Education-based, lifestyle intervention programs with unsupervised exercise improve outcomes in adults with metabolic syndrome. A systematic review and meta-analysis

To determine whether lifestyle intervention programs comprising dietary intervention and prescribed, unsupervised exercise improve outcomes for people with metabolic syndrome. A systematic review and meta-analysis of randomised controlled trials. Online databases CINAHL, MEDLINE, PubMed and Embase were searched from the earliest date available to October 2020. Post-intervention data were pooled to calculate mean differences (MD) or standardised mean differences (SMD) and 95% confidence intervals (CI) using inverse variance methods and random effects models. Trial methodological quality was assessed using the Physiotherapy Evidence Database (PEDro) scale and overall quality of each meta-analysis was assessed using the Grading of Recommendation Assessment, Development and Evaluation approach. Eleven studies from 9 randomised controlled trials with 1,835 participants were included. There was high quality evidence that lifestyle intervention programs with unsupervised exercise reduced waist circumference (MD -2.82 cm, 95%CI -5.64 to 0.00, I2 91%) and blood pressure (systolic: MD -3.89 mmHg, 95%CI -5.19 to -2.58, I2 4%; diastolic: MD -3.16 mmHg, 95%CI -4.83 to -1.49, I2 50%) and increased physical activity levels (SMD 0.47, 95%CI 0.24 to 0.70, I2 45%) when compared to usual care. There was low quality evidence that they improved quality of life (SMD 0.59, 95%CI 0.05 to 1.13, I2 84%). Unsupervised programs had no significant effect on fasting blood glucose (unless > 3 months duration), metabolic syndrome prevalence or cholesterol. Lifestyle intervention programs with prescribed, unsupervised exercise are a practical alternative to supervised programs for people with metabolic syndrome when time, access or resources are limited or when social distancing is required.

Skype Supervised, Individualized, Home-Based Rehabilitation Programs for Individuals With Rett Syndrome and Their Families - Parental Satisfaction and Point of View

Individuals with Rett syndrome (RTT) experience impaired gross motor skills limiting their capacity. Therefore, they need support to participate in physical activities, and it is crucial to work with primary caregivers when developing appropriate strategies, thereby leading to an active lifestyle. There is limited evidence supporting the effectiveness of remotely supported physical activity interventions. This project aimed to evaluate the effects of a skype-based, telehealth-delivered physical activity program carried out by participants’ parents at home. This article will focus on parental points of view. A mixed-methods design evaluating parental satisfaction was conducted. Forty participants with a confirmed genetic diagnosis of RTT and their families were recruited. The intervention included a 12-week individualized daily physical activity program carried out by participants’ parents and bi-weekly supervised by expert therapists. Parents’ impressions and feelings related to the program implementation were collected throughout semi-structured interviews, and an ad hoc developed questionnaire and discussed. The current project results suggest that a remote physical rehabilitation program, supported fortnightly by video calls, represents an effective way of conducting a remote physical therapy intervention for this population and that it can be easily carried out at home by primary caregivers, promoting positive functional changes, without bringing feelings of frustration due to the required workload. The strategies that families have learned during the program to support the motor activities of their daughters represent an easily performed set of tools that they can maintain and use in everyday life even after the cessation of the program.

Promoting physical activity and physical function in people with long-term conditions in primary care: the Function First realist synthesis with co-design

Background

As people age and accumulate long-term conditions, their physical activity and physical function declines, resulting in disability and loss of independence. Primary care is well placed to empower individuals and communities to reduce this decline; however, the best approach is uncertain.

Objectives

To develop a programme theory to explain the mechanisms through which interventions improve physical activity and physical function in people with long-term conditions in different primary care contexts, and to co-design a prototype intervention.

Data sources

Systematic literature searches of relevant databases with forwards and backwards citation tracking, grey literature searches and further purposive searches were conducted. Qualitative data were collected through workshops and interviews.

Design

Realist evidence synthesis and co-design for primary care service innovation.

Setting

Primary care in Wales and England.

Participants

Stakeholders included people with long-term conditions, primary care professionals, people working in relevant community roles and researchers.

Methods

The realist evidence synthesis combined evidence from varied sources of literature with the views, experiences and ideas of stakeholders. The resulting context, mechanism and outcome statements informed three co-design workshops and a knowledge mobilisation workshop for primary care service innovation.

Results

Five context, mechanism and outcome statements were developed. (1) Improving physical activity and function is not prioritised in primary care (context). If the practice team culture is aligned to the elements of physical literacy (mechanism), then physical activity promotion will become routine and embedded in usual care (outcome). (2) Physical activity promotion is inconsistent and unco-ordinated (context). If specific resources are allocated to physical activity promotion (in combination with a supportive practice culture) (mechanism), then this will improve opportunities to change behaviour (outcome). (3) People with long-term conditions have varying levels of physical function and physical activity, varying attitudes to physical activity and differing access to local resources that enable physical activity (context). If physical activity promotion is adapted to individual needs, preferences and local resources (mechanism), then this will facilitate a sustained improvement in physical activity (outcome). (4) Many primary care practice staff lack the knowledge and confidence to promote physical activity (context). If staff develop an improved sense of capability through education and training (mechanism), then they will increase their engagement with physical activity promotion (outcome). (5) If a programme is credible with patients and professionals (context), then trust and confidence in the programme will develop (mechanism) and more patients and professionals will engage with the programme (outcome). A prototype multicomponent intervention was developed. This consisted of resources to nurture a culture of physical literacy, materials to develop the role of a credible professional who can promote physical activity using a directory of local opportunities and resources to assist with individual behaviour change.

Limitations

Realist synthesis and co-design is about what works in which contexts, so these resources and practice implications will need to be modified for different primary care contexts.

Conclusions

We developed a programme theory to explain how physical activity could be promoted in primary care in people with long-term conditions, which informed a prototype intervention.

Future work

A future research programme could further develop the prototype multicomponent intervention and assess its acceptability in practice alongside existing schemes before it is tested in a feasibility study to inform a future randomised controlled trial.

Exercise Management Using a Mobile App in Patients With Parkinsonism: Prospective, Open-Label, Single-Arm Pilot Study

Background

Patients with parkinsonism have higher inactivity levels than the general population, and this results in increased comorbidities. Although exercise has benefits for motor function and quality of life (QOL) in patients with parkinsonism, these patients face many barriers to exercise participation, such as lack of motivation, fatigue, depression, and time constraints. Recently, the use of mobile apps has been highlighted as a remote exercise management strategy for patients with chronic diseases.

Objective

This study aimed to evaluate the effects of home-based exercise management with a customized mobile app on the exercise amount, physical activity, and QOL of patients with parkinsonism.

Methods

This was a prospective, open-label, single-arm pilot study. The therapist installed the app in the smartphones of the participants and educated them on how to use the app. The therapist developed an individualized multimodal exercise program that consisted of stretching, strengthening, aerobic, balance and coordination, and oral-motor and vocal exercises. Participants were encouraged to engage in an 8-week home-based exercise program delivered through a customized app. The alarm notifications of the app provided reminders to exercise regularly at home. The primary outcome was the exercise amount. The secondary outcomes were assessed using the International Physical Activity Questionnaire (IPAQ), Parkinson’s Disease Questionnaire-39 (PDQ-39), and Geriatric Depression Scale (GDS). The usability of the customized app was assessed using a self-report questionnaire.

Results

A total of 21 participants with parkinsonism completed the intervention and assessment between September and December 2020 (mean age: 72 years; women: 17/21, 81%; men: 4/21, 19%). The participants reported a significant increase in the total amount of exercise (baseline: mean 343.33, SD 206.70 min/week; 8-week follow-up: mean 693.10, SD 373.45 min/week; P<.001) and in the amount of each exercise component, including stretching, strengthening, balance and coordination, and oral-motor and vocal exercise after 8 weeks. Analysis of the secondary outcomes revealed significant improvements in the IPAQ (P=.006), PDQ-39 (P=.02), and GDS (P=.04) scores. The usability of the program with the mobile app was verified based on the positive responses such as “intention to use” and “role expectation for rehabilitation.”

Conclusions

Exercise management with a customized mobile app may be beneficial for improving exercise adherence, physical activity levels, depression management, and QOL in patients with parkinsonism. This remotely supervised technology-based, reinforcing, and multimodal exercise management strategy is recommended for use in patients with parkinsonism. In addition, this program proved useful as an alternative exercise management strategy during the COVID-19 pandemic when patients with Parkinson disease were less physically active than before and showed aggravation of symptoms. However, additional clinical trials are needed to evaluate the efficacy of this exercise program in a large population and to confirm its disease-modifying effects.

COVEPIC (Cognitive and spOrt Virtual EPIC training) investigating the effects of home-based physical exercise and cognitive training on cognitive and physical functions in community-dwelling older adults: study protocol of a randomized single-blinded clinical trial

BACKGROUND

In the context of the COVID-19 pandemic, lockdown and social distancing measures are applied to prevent the spread of the virus. It is well known that confinement and social isolation can have a negative impact on physical and mental health, including cognition. Physical activity and cognitive training can help enhance older adults' cognitive and physical health and prevent the negative collateral impacts of social isolation and physical inactivity. The COVEPIC study aims to document the effects of 6 months of home-based physical exercise alone versus home-based physical exercise combined with cognitive training on cognitive and physical functions in adults 50 years and older.

METHODS

One hundred twenty-two healthy older adults (> 50 years old) will be recruited from the community and randomized to one of the two arms for 6 months: (1) home-based physical exercises monitoring alone and (2) combined physical exercises monitoring with home-based cognitive training. The primary outcome is cognition, including general functioning (Montreal Cognitive Assessment (MoCA) score), as well as executive functions, processing speed, and episodic memory (composite Z-scores based on validated neuropsychological tests and computerized tasks). The secondary outcome is physical functions, including balance (one-leg stance test), gait and mobility performance (Timed Up and Go, 4-meter walk test), leg muscle strength (5-time sit-to-stand), and estimated cardiorespiratory fitness (Matthews' questionnaire). Exploratory outcomes include mood, anxiety, and health-related quality of life as assessed by self-reported questionnaires (i.e., Geriatric depression scale-30 items, Perceived stress scale, State-trait anxiety inventory-36 items, Perseverative thinking questionnaire, Connor-Davidson Resilience Scale 10, and 12-item Short Form Survey).

DISCUSSION

This trial will document the remote monitoring of home-based physical exercise alone and home-based physical combined with cognitive training to enhance cognitive and physical health of older adults during the COVID-19 pandemic period. Remote interventions represent a promising strategy to help maintain or enhance health and cognition in seniors, and potentially an opportunity to reach older adults in remote areas, where access to such interventions is limited.

'Function First': how to promote physical activity and physical function in people with long-term conditions managed in primary care? A study combining realist and co-design methods

OBJECTIVES

To develop a taxonomy of interventions and a programme theory explaining how interventions improve physical activity and function in people with long-term conditions managed in primary care. To co-design a prototype intervention informed by the programme theory.

DESIGN

Realist synthesis combining evidence from a wide range of rich and relevant literature with stakeholder views. Resulting context, mechanism and outcome statements informed co-design and knowledge mobilisation workshops with stakeholders to develop a primary care service innovation.

RESULTS

A taxonomy was produced, including 13 categories of physical activity interventions for people with long-term conditions.

ABRIDGED REALIST PROGRAMME THEORY

Routinely addressing physical activity within consultations is dependent on a reinforcing practice culture, and targeted resources, with better coordination, will generate more opportunities to address low physical activity. The adaptation of physical activity promotion to individual needs and preferences of people with long-term conditions helps affect positive patient behaviour change. Training can improve knowledge, confidence and capability of practice staff to better promote physical activity. Engagement in any physical activity promotion programme will depend on the degree to which it makes sense to patients and professions, and is seen as trustworthy.

CO-DESIGN

The programme theory informed the co-design of a prototype intervention to: improve physical literacy among practice staff; describe/develop the role of a physical activity advisor who can encourage the use of local opportunities to be more active; and provide materials to support behaviour change.

CONCLUSIONS

Previous physical activity interventions in primary care have had limited effect. This may be because they have only partially addressed factors emerging in our programme theory. The co-designed prototype intervention aims to address all elements of this emergent theory, but needs further development and consideration alongside current schemes and contexts (including implications relevant to COVID-19), and testing in a future study. The integration of realist and co-design methods strengthened this study.

Experiences of a home-based fall prevention exercise program among older adults with chronic lung disease

BACKGROUND

Individuals with chronic obstructive pulmonary disease (COPD) often have mobility limitations; these may include challenges with balance and being at high risk of falling. Risk of falling can be reduced through exercise programs targeting balance; however, older adults with COPD may experience many barriers to exercise adherence. In this paper we present qualitative findings about the feasibility of a six-month home-based fall-prevention exercise program for older adults with COPD. The aim of the study is to describe the experiences of older adults with COPD who participated in a home-based fall prevention exercise program in order to determine their perceived facilitators and barriers to participation.

METHODS

15 participants with COPD who had completed the six-month home-based program participated in one-on-one semi-structured interviews over the phone. Interpretive description methodology and thematic analysis were used.

RESULTS

Two major themes emerged with respect to participants' perspectives of the intervention and facilitators and barriers to participation: program personalization based on each individual's characteristics, lifestyles, and preferences; and self-motivation and support from family, friends, and healthcare providers.

CONCLUSIONS

Fall prevention exercise programs that are personalized and focus on providing support for older adults with COPD may help to improve adherence and reduce participants' risk of falling.Implications for rehabilitationIndividuals with COPD often have balance problems and a high risk of falling.Fall prevention programs can improve balance, but adherence is a commonly cited challenge.Patient experiences suggest that fall prevention programs should be personalized and incorporate social support to improve adherence to fall prevention exercises.

Feasibility of a 6-Month Home-Based Fall Prevention Exercise Program in Older Adults with COPD

Purpose

Older adults with chronic obstructive pulmonary disease (COPD) have a high risk and rate of falls. Home-based fall prevention exercise programs reduce falls in older adults and may be an alternative approach for people with COPD without access to hospital-based rehabilitation. Therefore, we aimed to determine the feasibility of a home-based fall prevention exercise program in older adults with COPD and to examine the effect of the program on fall-related outcomes at baseline, 3 and 6 months.

Patients and Methods

Adults ≥60 years with COPD at risk for falls participated in a single group study. The intervention was a 6-month home-based fall prevention program which included 40 minutes of independent exercise three times per week, four physiotherapist home visits, bimonthly phone calls, and an optional booster session post-exacerbation. An independent assessor collected outcome measures at home at baseline, 3- and 6-months. Primary feasibility criteria were recruitment and retention rates (≥70%) and exercise adherence (≥60%). Functional outcomes included the Berg Balance Scale (BBS), the Balance Evaluation Systems Test (BESTest), the Activities-Specific Balance Confidence (ABC) scale, the repeated chair-stand test, self-reported function, and fall history.

Results

Thirty-six patients (female 63.8%, mean age 74.4 ± 6.1 years; mean FEV₁ 45.0 ± 13.8% predicted) were enrolled. The recruitment rate was 46.8%, participant retention rate was 69.4%, and exercise adherence rate was 73.6%. Repeated measures ANOVA showed improvements at 3- and 6-months compared to baseline in the BBS (p=0.001) and the BESTest total scores and sub-scores (p=0.001).

Conclusion

The home-based fall prevention exercise program met one of the three pre-specified feasibility criteria (exercise adherence), and improved balance-related measures of fall risk in older adults with COPD. Our findings highlight important opportunities for refinement of the study design prior to undertaking a full-scale trial.

Interventions for promoting physical activity in people with neuromuscular disease

BACKGROUND

The World Health Organization (WHO) recommends that people of all ages take regular and adequate physical activity. If unable to meet the recommendations due to health conditions, international guidance advises being as physically active as possible. Evidence from community interventions of physical activity indicate that people living with medical conditions are sometimes excluded from participation in studies. In this review, we considered the effects of activity-promoting interventions on physical activity and well-being in studies, as well as any adverse events experienced by participants living with inherited or acquired neuromuscular diseases (NMDs).  OBJECTIVES: To assess the effects of interventions designed to promote physical activity in people with NMD compared with no intervention or alternative interventions.

SEARCH METHODS

On 30 April 2020, we searched Cochrane Neuromuscular Specialised Register, CENTRAL, Embase, MEDLINE, and ClinicalTrials.Gov. WHO ICTRP was not accessible at the time.

SELECTION CRITERIA

We considered randomised or quasi-randomised trials, including cross-over trials, of interventions designed to promote physical activity in people with NMD compared to no intervention or alternative interventions. We specifically included studies that reported physical activity as an outcome measure. Our main focus was studies in which promoting physical activity was a stated aim but we also included studies in which physical activity was assessed as a secondary or exploratory outcome.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane procedures.

MAIN RESULTS

The review included 13 studies (795 randomised participants from 12 studies; number of participants unclear in one study) of different interventions to promote physical activity. Most studies randomised a minority of invited participants. No study involved children or adolescents and nine studies reported minimal entry criteria for walking. Participants had one of nine inherited or acquired NMDs. Types of intervention included structured physical activity support, exercise support (as a specific form of physical activity), and behaviour change support that included physical activity or exercise. Only one included study clearly reported that the aim of intervention was to increase physical activity. Other studies reported or planned to analyse the effects of intervention on physical activity as a secondary or exploratory outcome measure. Six studies did not report results for physical activity outcomes, or the data were not usable. We judged 10 of the 13 included studies at high or unclear risk of bias from incomplete physical activity outcome reporting. We did not perform a meta-analysis for any comparison because of differences in interventions and in usual care. We also found considerable variation in how studies reported physical activity as an outcome measure. The studies that reported physical activity measurement did not always clearly report intention-to-treat (ITT) analysis or whether final assessments occurred during or after intervention. Based on prespecified measures, we included three comparisons in our summary of findings. A physical activity programme (weight-bearing) compared to no physical activity programme One study involved adults with diabetic peripheral neuropathy (DPN) and reported weekly duration of walking during and at the end of a one-year intervention using a StepWatch ankle accelerometer. Based on the point estimate and low-certainty evidence, intervention may have led to an important increase in physical activity per week; however, the 95% confidence interval (CI) included the possibility of no difference or an effect in either direction at three months (mean difference (MD) 34 minutes per week, 95% CI -92.19 to 160.19; 69 participants), six months (MD 68 minutes per week, 95% CI -55.35 to 191.35; 74 participants), and 12 months (MD 49 minutes per week, 95% CI -75.73 to 173.73; 70 participants). Study-reported effect estimates for foot lesions and full-thickness ulcers also included the possibility of no difference, a higher, or lower risk with intervention. A sensor-based, interactive exercise programme compared to no sensor-based, interactive exercise programme One study involved adults with DPN and reported duration of walking over 48 hours at the end of four weeks' intervention using a t-shirt embedded PAMSys sensor. It was not possible to draw conclusions about the effectiveness of the intervention from the very low-certainty evidence (MD -0.64 hours per 48 hours, 95% CI -2.42 to 1.13; 25 participants). We were also unable to draw conclusions about impact on the Physical Component Score (PCS) for quality of life (MD 0.24 points, 95% CI -5.98 to 6.46; 35 participants; very low-certainty evidence), although intervention may have made little or no difference to the Mental Component Score (MCS) for quality of life (MD 5.10 points, 95% CI -0.58 to 10.78; 35 participants; low-certainty evidence). A functional exercise programme compared to a stretching exercise programme One study involved adults with spinal and bulbar muscular atrophy and reported a daily physical activity count at the end of 12 weeks' intervention using an Actical accelerometer. It was not possible to draw conclusions about the effectiveness of either intervention (requiring compliance) due to low-certainty evidence and unconfirmed measurement units (MD -8701, 95% CI -38,293.30 to 20,891.30; 43 participants). Functional exercise may have made little or no difference to quality of life compared to stretching (PCS: MD -1.10 points, 95% CI -5.22 to 3.02; MCS: MD -1.10 points, 95% CI -6.79 to 4.59; 49 participants; low-certainty evidence). Although studies reported adverse events incompletely, we found no evidence of supported activity increasing the risk of serious adverse events.

AUTHORS' CONCLUSIONS

We found a lack of evidence relating to children, adolescents, and non-ambulant people of any age. Many people living with NMD did not meet randomised controlled trial eligibility criteria. There was variation in the components of supported activity intervention and usual care, such as physical therapy provision. We identified variation among studies in how physical activity was monitored, analysed, and reported. We remain uncertain of the effectiveness of promotional intervention for physical activity and its impact on quality of life and adverse events. More information is needed on the ITT population, as well as more complete reporting of outcomes. While there may be no single objective measure of physical activity, the study of qualitative and dichotomous change in self-reported overall physical activity might offer a pragmatic approach to capturing important change at an individual and population level.

Key Factors Associated with Adherence to Physical Exercise in Patients with Chronic Diseases and Older Adults: An Umbrella Review

Physical inactivity is a major concern and poor adherence to exercise programs is often reported. The aim of this paper was to systematically review published reviews on the study of adherence to physical exercise in chronic patients and older adults and to identify those adherence-related key factors more frequently suggested by reviews for that population. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Results were classified considering the target population and participants' characteristics to identify the most repeated factors obtained for each condition. Fifty-five articles were finally included. Fourteen key factors were identified as relevant to increase adherence to physical exercise by at least ten reviews: (a) characteristics of the exercise program, (b) involvement of professionals from different disciplines, (c) supervision, (d) technology, (e) initial exploration of participant's characteristics, barriers, and facilitators, (f) participants education, adequate expectations and knowledge about risks and benefits, (g) enjoyment and absence of unpleasant experiences, (h) integration in daily living, (i) social support and relatedness, (j) communication and feedback, (k) available progress information and monitoring, (l) self-efficacy and competence, (m) participant's active role and (n) goal setting. Therefore, adherence to physical exercise is affected by several variables that can be controlled and modified by researchers and professionals.

A User Study on the Feasibility and Acceptance of Delivering Physical Activity Programs to Older Adults through Conversational Agents

The implementation of evidence-based physical activity (PA) programs for older adults is limited in part due to the administration-related personnel costs. The rapid growth of the off-the-shelf smart speakers, conversational agents (CAs), demonstrates the potential of scalable delivery of PA programs to older adults at home. We implemented a PA virtual coach based on an evidence-based PA program on a Google Home device, and conducted a user study to examine how older adults interact with the virtual coach. Results suggested that all older adults were able to complete the PA program with guidance from the virtual coach, and showed high acceptance and intentions to use CAs in the future. Analyses on conversation turn-taking further suggested that all older adults (including 80% novice CAs users) experienced minimum difficulty talking with the PA virtual coach. Relationships among age, technology acceptance, conversation patterns and the perceived sociability of CAs are also discussed.

Promoting Physical Activity Among Older Adults Using Community-Based Participatory Research With an Adapted PRECEDE-PROCEED Model Approach: The AEQUIPA/OUTDOOR ACTIVE Project

PURPOSE

The PRECEDE-PROCEED model (PPM) is a community-based participatory research (CBPR) framework for health promotion, yet the direct application of the PPM into practice is unclear. This paper describes how the PPM was adapted for the development and application of a pilot intervention study to promote outdoor physical activity (PA) in older adults (OUTDOOR ACTIVE). We illustrate the steps and adaptations we applied to put the PPM into practice and present the developed interventions.

DESIGN

The PPM was adapted by incorporating a socio-ecological model. This ensured the design of any resultant intervention would explicitly address multi-level determinants of physical activity. The list of possible program components to select from for the design of an intervention was also extended.

SETTING

Bremen, Germany.

PARTICIPANTS

Participants in the intervention development were 924 noninstitutionalized older adults, aged 65-75 years (response: 25.2%), living in Bremen-Hemelingen, Germany. For implementation of the intervention and to ensure sustainability, several groups of stakeholders were involved throughout the process.

METHODS

A mixed method design was employed (e.g., focus groups, quantitative survey) to identify determinants. A round table and participatory workshops were held to involve the target group and community stakeholders in the design of an intervention using the adapted PPM model.

RESULTS

A conceptual model was developed illustrating the integration of a socio-ecological model into the PPM. The model received ecological validity, as it was affirmed by community stakeholders as an appropriate method for designing a community-level PA intervention. Target goals to address PA determinants were selected by target group members. An intervention to meet the goals was developed and implemented with target group input.

CONCLUSION

The adapted PPM is a promising starting point for developing multi-level interventions. Steps should be taken to ensure all social groups are participating in the process and all levels of determinants are addressed.

Exercise/physical activity and health outcomes: an overview of Cochrane systematic reviews

BACKGROUND

Sedentary lifestyle is a major risk factor for noncommunicable diseases such as cardiovascular diseases, cancer and diabetes. It has been estimated that approximately 3.2 million deaths each year are attributable to insufficient levels of physical activity. We evaluated the available evidence from Cochrane systematic reviews (CSRs) on the effectiveness of exercise/physical activity for various health outcomes.

METHODS

Overview and meta-analysis. The Cochrane Library was searched from 01.01.2000 to issue 1, 2019. No language restrictions were imposed. Only CSRs of randomised controlled trials (RCTs) were included. Both healthy individuals, those at risk of a disease, and medically compromised patients of any age and gender were eligible. We evaluated any type of exercise or physical activity interventions; against any types of controls; and measuring any type of health-related outcome measures. The AMSTAR-2 tool for assessing the methodological quality of the included studies was utilised.

RESULTS

Hundred and fifty CSRs met the inclusion criteria. There were 54 different conditions. Majority of CSRs were of high methodological quality. Hundred and thirty CSRs employed meta-analytic techniques and 20 did not. Limitations for studies were the most common reasons for downgrading the quality of the evidence. Based on 10 CSRs and 187 RCTs with 27,671 participants, there was a 13% reduction in mortality rates risk ratio (RR) 0.87 [95% confidence intervals (CI) 0.78 to 0.96]; I2 = 26.6%, [prediction interval (PI) 0.70, 1.07], median effect size (MES) = 0.93 [interquartile range (IQR) 0.81, 1.00]. Data from 15 CSRs and 408 RCTs with 32,984 participants showed a small improvement in quality of life (QOL) standardised mean difference (SMD) 0.18 [95% CI 0.08, 0.28]; I2 = 74.3%; PI -0.18, 0.53], MES = 0.20 [IQR 0.07, 0.39]. Subgroup analyses by the type of condition showed that the magnitude of effect size was the largest among patients with mental health conditions.

CONCLUSION

There is a plethora of CSRs evaluating the effectiveness of physical activity/exercise. The evidence suggests that physical activity/exercise reduces mortality rates and improves QOL with minimal or no safety concerns.

Relationship of Forced Social Distancing and Home Confinement Derived from the COVID-19 Pandemic with the Occupational Balance of the Spanish Population

Abrupt interruption in the performance of everyday occupations as a consequence of forced social distancing and home confinement, coupled with a lack of regulatory capacities and skills, can trigger harmful effects on people's health and well-being. This study aimed to determine the factors related to the occupational balance in the Spanish population during home confinement as a consequence of the coronavirus disease 19 (COVID-19) pandemic. A total of 3261 subjects completed an online survey, which was disseminated through the mainstream social media platforms in Spain and included the Occupational Balance Questionnaire (OBQ), sociodemographic variables, and factors related to COVID-19 infection. The mean age of the participants (81.69% women) was 40.53 years (SD ± 14.05). Sociodemographic variables were related to a greater occupational balance, and the multivariate analysis showed that age (β = 0.071; p = 0.001), the perception of having received enough information (β = 0.071; p ≤ 0.001), not telecommuting (β = -0.047; p = 0.022), and not being infected by COVID-19 (β = 0.055; p = 0.007) contributed to a better occupational balance. There were profiles of people less likely to suffer disturbances in occupational balance during home confinement, but more studies are needed to help understand and analyze the effects of the COVID-19 pandemic on people's occupational and mental health.

Social Cognition and Socioecological Predictors of Home-Based Physical Activity Intentions, Planning, and Habits during the COVID-19 Pandemic

'Shelter in place' and 'lockdown' orders implemented to minimize the spread of COVID-19 have reduced opportunities to be physically active. For many, the home environment emerged as the only viable option to participate in physical activity. Previous research suggests that availability of exercise equipment functions as a determinant of home-based physical activity participation among the general adult population. The purpose of this study was to use a socioecological framework to investigate how the availability of exercise equipment at home predicts behavioral decisions, namely, intention, planning, and habits with respect to participation in physical activity. Participants (n = 429) were adults recruited in U.S. states subject to lockdown orders during the pandemic who completed measures online. A structural equation model indicated that availability of cardiovascular and strength training equipment predicted physical activity planning. Social cognition constructs mediated the relationship between each type of exercise equipment and intentions. Autonomous motivation and perceived behavioral control were found to mediate the relationship between each type of exercise equipment and habit. The availability of large cardiovascular and strength training equipment demonstrated significant predictive effects with intention, planning, habit, and autonomous motivation. Facilitating these constructs for home-based physical activity interventions could be efficacious for promoting physical activity.

Motion-Based Technology for People With Dementia Training at Home: Three-Phase Pilot Study Assessing Feasibility and Efficacy

BACKGROUND

Persons with dementia tend to be vulnerable to mobility challenges and hence face a greater risk of fall and subsequent fractures, morbidity, and mortality. Motion-based technologies (MBTs), also called sensor-based technologies or virtual reality, have the potential for assisting physical exercise and training as a part of a disease management and rehabilitation program, but little is known about its' use for people with dementia.

OBJECTIVE

The purpose of this pilot study was to investigate the feasibility and efficacy of MBT physical training at home for people with dementia.

METHODS

A 3-phase pilot study: (1) baseline start-up, (2) 15 weeks of group training at a local care center twice a week, and (3) 12 weeks of group training reduced to once a week, supplemented with individual MBT training twice a week at home. A total of 26 people with dementia from a municipality in Southern Denmark were eligible and agreed to participate in this study. Three withdrew from the study, leaving 23 participants for the final analysis. Feasibility was measured by the percentage of participants who trained with MBT at home, and their completion rate of total scheduled MBT sessions. Efficacy was evaluated by physical function, measured by Sit-to-Stand (STS), Timed-Up-and-Go (TUG), 6-minute Walk Test (6MW), and 10-meter Dual-task Walking Test (10MDW); cognitive function was measured by Mini-Mental State Examination (MMSE) and Neuropsychiatric Inventory-Questionnaire (NPI-Q); and European Quality of Life 5 dimensions questionnaire (EQOL5) was used for measuring quality of life. Descriptive statistics were applied accordingly. Wilcoxon signed-rank and rank-sum tests were applied to explore significant differences within and between the groups.

RESULTS

As much as 12 of 23 participants (52%) used the supplemental MBT training at home. Among them, 6 (50%) completed 75% or more scheduled sessions, 3 completed 25% or less, and 3 completed between 25% and 75% of scheduled sessions. For physical and cognitive function tests, supplementing with MBT training at home showed a tendency of overall stabilization of scores among the group of participants who actively trained with MBT; especially, the 10MDW test even showed a significant improvement from 9.2 to 7.1 seconds (P=.03). We found no positive effect on EQOL5 tests.

CONCLUSIONS

More than half of the study population with dementia used MBT training at home, and among them, half had an overall high adherence to the home training activity. Physical function tended to remain stable or even improved among high-adherence MBT individuals. We conclude that MBT training at home may be feasible for some individuals with dementia. Further research is warranted.

Formative Evaluation of Consumer-Grade Activity Monitors Worn by Older Adults: Test-Retest Reliability and Criterion Validity of Step Counts

Background

To assess whether commercial-grade activity monitors are appropriate for measuring step counts in older adults, it is essential to evaluate their measurement properties in this population.

Objective

This study aimed to evaluate test-retest reliability and criterion validity of step counting in older adults with self-reported intact and limited mobility from 6 commercial-grade activity monitors: Fitbit Charge, Fitbit One, Garmin vívofit 2, Jawbone UP2, Misfit Shine, and New-Lifestyles NL-1000.

Methods

For test-retest reliability, participants completed two 100-step overground walks at a usual pace while wearing all monitors. We tested the effects of the activity monitor and mobility status on the absolute difference in step count error (%) and computed the standard error of measurement (SEM) between repeat trials. To assess criterion validity, participants completed two 400-meter overground walks at a usual pace while wearing all monitors. The first walk was continuous; the second walk incorporated interruptions to mimic the conditions of daily walking. Criterion step counts were from the researcher tally count. We estimated the effects of the activity monitor, mobility status, and walk interruptions on step count error (%). We also generated Bland-Altman plots and conducted equivalence tests.

Results

A total of 36 individuals participated (n=20 intact mobility and n=16 limited mobility; 19/36, 53% female) with a mean age of 71.4 (SD 4.7) years and BMI of 29.4 (SD 5.9) kg/m². Considering test-retest reliability, there was an effect of the activity monitor (P<.001). The Fitbit One (1.0%, 95% CI 0.6% to 1.3%), the New-Lifestyles NL-1000 (2.6%, 95% CI 1.3% to 3.9%), and the Garmin vívofit 2 (6.0%, 95 CI 3.2% to 8.8%) had the smallest mean absolute differences in step count errors. The SEM values ranged from 1.0% (Fitbit One) to 23.5% (Jawbone UP2). Regarding criterion validity, all monitors undercounted the steps. Step count error was affected by the activity monitor (P<.001) and walk interruptions (P=.02). Three monitors had small mean step count errors: Misfit Shine (−1.3%, 95% CI −19.5% to 16.8%), Fitbit One (−2.1%, 95% CI −6.1% to 2.0%), and New-Lifestyles NL-1000 (−4.3%, 95 CI −18.9% to 10.3%). Mean step count error was larger during interrupted walking than continuous walking (−5.5% vs −3.6%; P=.02). Bland-Altman plots illustrated nonsystematic bias and small limits of agreement for Fitbit One and Jawbone UP2. Mean step count error lay within an equivalence bound of ±5% for Fitbit One (P<.001) and Misfit Shine (P=.001).

Conclusions

Test-retest reliability and criterion validity of step counting varied across 6 consumer-grade activity monitors worn by older adults with self-reported intact and limited mobility. Walk interruptions increased the step count error for all monitors, whereas mobility status did not affect the step count error. The hip-worn Fitbit One was the only monitor with high test-retest reliability and criterion validity.

Exercise Programs for Muscle Mass, Muscle Strength and Physical Performance in Older Adults with Sarcopenia: A Systematic Review and Meta-Analysis

Sarcopenia is an age-related condition that is characterized by progressive and generalized loss of muscle mass and function. Exercise treatment has been the most commonly used intervention among elderly populations. We performed a systematic review and meta-analysis to evaluate the available literature related to the effects of exercise interventions/programs on muscle mass, muscle strength and physical performance in older adults with sarcopenia. We searched PubMed, EMBASE, MEDLINE and the Web of Science for randomized controlled trials and controlled clinical trials exploring exercise in older adults with sarcopenia published through July 2019 without any language restrictions. Pooled analyses were conducted using Review Manager 5.3, with standardized mean differences (SMDs) and fixed-effect models. A total of 3898 titles and abstracts were initially identified, and 22 studies (1041 individuals, 80.75% females, mean age ranged from 60.51 to 85.90 years) were included in the meta-analysis. The exercise programs in the studies consisted of 30 to 80 min of training, with 1 to 5 training sessions weekly for 6 to 36 weeks. Muscle strength (grip strength [SMD 0.57, 95 % CI 0.42 to 0.73, P <0.00001] and timed five chair stands [SMD -0.56, 95 % CI -0.85 to -0.28, P < 0.0001]) and physical performance (gait speed [SMD 0.44, 95 % CI 0.26 to 0.61, P < 0.00001] and the timed up and go test [SMD -0.97, 95 % CI -1.22 to -0.72, P < 0.00001]) showed significant improvement following exercise treatment, while no differences in muscle mass (ASM [SMD 0.15, 95 % CI -0.05 to 0.36, P = 0.15] and ASM/height² [SMD 0.21, 95 % CI -0.05 to 0.48, P = 0.12]) were detected. Exercise programs showed overall significant positive effects on muscle strength and physical performance but not on muscle mass in sarcopenic older adults.

The EX-FRAIL CKD trial: a study protocol for a pilot randomised controlled trial of a home-based EXercise programme for pre-frail and FRAIL, older adults with Chronic Kidney Disease

INTRODUCTION

Frailty is highly prevalent in adults with chronic kidney disease (CKD) and is associated with adverse health outcomes including falls, poorer health-related quality of life (HRQOL), hospitalisation and mortality. Low physical activity and muscle wasting are important contributors to physical frailty in adults with CKD. Exercise training may improve physical function and frailty status leading to associated improvements in health outcomes, including HRQOL. The EX-FRAIL CKD trial aims to inform the design of a definitive randomised controlled trial (RCT) that investigates the effectiveness of a progressive, multicomponent home-based exercise programme in prefrail and frail older adults with CKD.

METHODS AND ANALYSIS

The EX-FRAIL CKD trial is a two-arm parallel group pilot RCT. Participants categorised as prefrail or frail, following Frailty Phenotype (FP) assessment, will be randomised to receive exercise or usual care. Participants randomised to the intervention arm will receive a tailored 12-week exercise programme, which includes weekly telephone calls to advise on exercise progression. Primary feasibility outcome measures include rate of recruitment, intervention adherence, outcome measure completion and participant attrition. Semistructured interviews with a purposively selected group of participants will inform the feasibility of the randomisation procedures, outcome measures and intervention. Secondary outcome measures include physical function (walking speed and Short Physical Performance Battery), frailty status (FP), fall concern (Falls Efficacy Scale-International tool), activities of daily living (Barthel Index), symptom burden (Palliative care Outcome Scale-Symptoms RENAL) and HRQOL (Short Form-12v2).

ETHICS AND DISSEMINATION

Ethical approval was granted by a National Health Service (NHS) Regional Ethics Committee and the NHS Health Research Authority. The study team aims to publish findings in a peer-reviewed journal and presents the results at relevant national and international conferences. A summary of findings will be provided to participants, a local kidney patient charity and the funding body.

COVID-19 Confinement and Health Risk Behaviors in Spain

The World Health Organization (WHO) has declared a world pandemic due to COVID-19. In response, most affected countries have enacted measures involving compulsory confinement and restrictions on free movement, which likely influence citizens' lifestyles. This study investigates changes in health risk behaviors (HRBs) with duration of confinement. An online cross-sectional survey served to collect data about the Spanish adult population regarding health behaviors during the first 3 weeks of confinement. A large sample of participants (N = 2,741) (51.8% women; mean age 34.2 years [SD 13.0]) from all Spanish regions completed the survey. Binomial logistic regressions adjusted for socioeconomic characteristics (i.e., gender, age, civil status, education, and occupation), body mass index (BMI), previous HRBs, and confinement context (i.e., solitude and exposure to COVID-19) were conducted to investigate associations between the number of weeks confined and a set of six HRBs (physical activity, alcohol consumption, fresh fruit and vegetable consumption, smoking, screen exposure, and sleep hours). When adjusted, we observed significantly lower odds of experiencing a higher number of HRBs than before confinement overall in a time-dependent fashion: OR 0.63; 95% CI: 0.49-0.81 for the second and OR 0.47; 95% CI: 0.36-0.61 for the third week of confinement. These results were equally consistent in all age and gender subgroup analyses. The present study indicates that changes toward a higher number of HRBs than before confinement, as well as the prevalence of each HRB except screen exposure, decreased during the first 3 weeks of COVID-19 confinement, and thus the Spanish adult population may have adapted to the new situational context by gradually improving their health behaviors.

Gaming Console Home-Based Exercise for Adults with Cystic Fibrosis: Study Protocol

BACKGROUND

Despite evidence of exercise benefits to lung function, adherence to routine exercise in adults with cystic fibrosis (CF) is low. The incorporation of interactive virtual reality video exergame activities in home-based programs as an incentive may help improve motivation and adherence to exercise. This proposed study will attempt to improve the physical fitness and respiratory function of sedentary adults with CF by engaging them in a Nintendo Wii Fit Plus™ home-based exercise program.

METHODS

A single group pretest-posttest design will be used to examine the immediate (12-weeks) and long-term effect (24-weeks) of a home-based exergame program on improving pulmonary-related function (physical fitness and respiratory function) in sedentary adults with CF. Participants will receive a one-time orientation to the Wii Fit Plus, and will be requested to use it to exercise according to the recommended guidelines 3 times a week for 30 min in the following 24 weeks. Monthly phone monitoring will be conducted during the first 12 weeks. Besides evaluating the efficacy of a home-based exergame program on improving aerobic capacity, physical activity, and respiratory-related symptoms, we will examine the impact of the exergame on airway ion transport as measured by nasal potential difference, which will be collected at baseline and at the end of 12-weeks only.

DISCUSSION

This is the first study to evaluate the feasibility, acceptability and potential effectiveness of a low-cost exercise avenue (i.e., exergames) for adults with CF to improve their pulmonary-related function, which is important for CF disease management and prevention of complications. In addition, the proposed study will be the first to investigate the therapeutic efficacy of home-based exergames on airway ion transport among adults with CF. Through an increase in physical activity, it is expected that participants will improve their physical fitness and respiratory function at the end of the study.

General strength and conditioning versus motor control with manual therapy for improving depressive symptoms in chronic low back pain: A randomised feasibility trial

Objectives

Exercise can be used as a treatment for depressive symptoms in the general population. However, little is known as to whether exercise has mental health benefits for adults experiencing chronic low back pain (CLBP). The aim of this study was to examine the feasibility of two intervention protocols commonly used in clinical practice for treating chronic low back pain, but with differing exercise dose, on depressive symptoms.

Methods

Forty men and women (mean age = 35) experiencing chronic persistent (>3 months), non-specific low back pain were recruited into a randomised clinical trial during 2015–2016. Participants were randomised to receive motor control (low-dose exercise) and manual therapy (n = 20), or general strength and conditioning training (moderate-dose exercise) (n = 20). Depressive symptoms were assessed fortnightly throughout a 6-month follow-up period using the Centre for Epidemiologic Studies Depression Scale (CES-D 10). Linear mixed models were used to examine within-group and between-group changes in depressive symptoms.

Results

Mean CES-D 10 score at baseline was 9.17 (SD = 4.32). There was evidence of a small decrease in average depressive symptoms over time (β -0.19 per fortnight, 95% CI = -0.34, -0.02). However, there was no evidence that change over time was dependent on treatment group.

Conclusions

Reduction in depressive symptoms amongst adults with CLBP occurred with both treatment methods (motor control [low-dose exercise] and manual therapy; or general strength and conditioning [moderate-dose exercise]). Further interventions including a true control group are needed to draw conclusions as to the effectiveness of each of these treatment methods on depressive symptoms amongst adults with CLBP.

First proposal of quality indicators and standards and recommendations to improve the healthcare in the Spanish National Registry of Hip Fracture

BACKGROUND

The Spanish National Hip Fracture Registry (or Registro Nacional de Fractura de Cadera, RNFC) is a database of hip fracture patients admitted to Spanish hospitals. Its goals include assessment and continuous improvement of the care process.

OBJECTIVES

To (1) establish a series of indicators, (2) evaluate their initial fulfillment, (3) propose quality standards, (4) suggest recommendations to facilitate standards compliance, and (5) monitor the indicators.

METHOD

The indicators fulfilled the criteria of (1) evaluating the process or outcome, (2) being clinically relevant for patients, (3) being modifiable through changes in healthcare practice, and (4) being considered important by the RNFC participants. The first quartile obtained by the group of hospitals in each of the respective variables was proposed as the standard. The Indicators Advisory Committee (IAC) elaborated a list of recommendations for each indicator, based on the available evidence.

RESULTS

Seven indicators were chosen. These indicators (its baseline compliance vs. the standard to be reached, respectively) were: the proportion of patients receiving surgery within 48h (44% vs. 63%), mobilized the first postoperative day (56% vs. 86%), with antiosteoporotic medication at discharge (32% vs. 61%), with calcium supplements at discharge (46% vs. 77%), with vitamin D supplements at discharge (67% vs. 92%), who developed pressure ulcers during hospitalization (7.2% vs. 2.1%) and with independent mobility at 30 days (58% vs. 70%). The IAC has established 25 recommendations for improving care.

CONCLUSION

The indicators and standards chosen are presented, as well as the list of recommendations. This process completes the first step to improve quality of care. The results will be evaluated 6 months after implementing the recommendations.

Feasibility of preoperative supervised home-based exercise in older adults undergoing colorectal cancer surgery - A randomized controlled design

Preoperative physical exercise is emerging as a growing field of research globally. There are still challenges in recruiting vulnerable older people, and time constraints in preoperative cancer care to consider. We therefore evaluated the feasibility of short-term supervised home-based exercise in older people prior to colorectal cancer surgery. This feasibility study was conducted between September 2016 and June 2018. People ≥70 years scheduled for colorectal cancer surgery were recruited and randomized to an intervention group receiving supervised home-based physical exercise at a high level of estimated exertion or a standard care group following the standard preoperative path. The exercise (respiratory, strength, and aerobic) consisted of 2–3 supervised sessions a week in the participants’ homes, for at least 2–3 weeks or until surgery, and a self-administered exercise program in between. The primary outcome was process feasibility, including aspects specifically related to recruitment rate, compliance to the intervention, and acceptability. The secondary outcome was scientific feasibility including treatment safety, description of dose level and response, and estimation of treatment results. Twenty-three participants were included (recruitment rate 35%). A median of 6 supervised sessions was conducted over a 17-day exercise period. Compliance with the supervised sessions was 97%, and participants found the intervention acceptable. Concerning the self-administered exercise, a median of 19 inspiratory muscle training, 6 functional strength, and 8.5 aerobic sessions were reported. Challenges reported by program instructors were time constraints and difficulties in achieving high exercise intensities on the Borg CR-10 scale. A statistically significant between-group difference was only found in inspiratory muscle strength, favoring the intervention group (p<0.01). A short-term preoperative supervised home-based physical exercise intervention can be conducted, with respect to compliance and acceptability, in older people with similar physical status as in this study prior to colorectal cancer surgery. However, modifications are warranted with respect to improving recruitment rates and achieving planned intensity levels prior to conducting a definitive trial.

Effect of a home-based exercise program on functional mobility and quality of life in elderly people: protocol of a single-blind, randomized controlled trial

Background

Elderly people have high rates of functional decline, which compromises independence, self-confidence, and quality of life (QoL). Physical exercise leads to significant improvements in strength, balance, functional mobility, and QoL, but there is still reduced access to this therapeutic strategy due to difficulties in locomotion to training centers or lack of adaptation to the exercise environment.

Methods/design

The purpose of this clinical trial will be to verify the effect of a progressive and semi-supervised, home-based exercise program on the functional mobility, and in the QoL of sedentary elderly people. This is a protocol of a consecutive, single-center, single-blind, and randomized controlled trial. The design, conduct, and report follows the SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials) guidelines. Sedentary elderly people will be enrolled, and randomly allocated into two groups. The intervention group will perform exercises in their own home and the control group will not perform exercises. The evaluations will occur at study enrollment and after 3 months of intervention, and will be performed using the functional mobility Timed Up & Go (TUG) test and sociodemographic and QoL questionnaires. In the statistical analysis, comparisons of mean and correlation analyses will be performed. The primary expected outcome is the improvement in functional mobility verified through the TUG test and the secondary outcome is the improvement in QoL verified by the WHOQOL-OLD.

Discussion

The lack of scientific evidence demonstrating the benefits of semi-supervised home exercise on functional mobility and QoL in elderly people represents an obstacle to the development of guidelines for clinical practice and for policy-makers. The World Health Organization highlighted the importance of musculoskeletal health programs for elderly people, and the exercise program described in this protocol was designed to be viable, easy to implement, and inexpensive, and could be performed at the home of elderly subjects after receiving only guidelines and follow-up via periodic visits. Based on these facts, we hope that this study will demonstrate that a well-structured, home-based exercise program can be effective in improving functional mobility and QoL of sedentary elderly people, even without constant supervision during exercise.

Impact of a home-based nutrition and exercise intervention in improving functional capacity associated with falls among rural seniors in Canada

Purpose

A six-month randomized controlled trial was conducted to examine the impact of a home-based nutrition and exercise intervention on functional capacity to prevent falls among rural seniors. The paper aims to discuss this issue.

Design/methodology/approach

Men and women (n=134), aged 60 and older were assigned to one of four groups: exercise, nutrition, exercise-nutrition, and control. Participants in the exercise and exercise-nutrition groups performed a home-based exercise program (Home Support Exercise Program), and the nutrition and exercise-nutrition groups received a liquid nutritional supplement (Ensure®) for six months. Participants were assessed at baseline and six months on functional mobility, balance, flexibility and endurance.

Findings

There were significant group differences over time for functional reach and the Timed Up and Go test, with significant differences existing between exercise and nutrition-exercise, and exercise and nutrition groups respectively. Overall, the exercise group out-performed the other groups in terms of functional capacity and psychological well-being.

Research implications

Improvement of functional health among rural seniors is achievable through the delivery of a home-based intervention focusing on exercise and nutrition.

Practical implications

The study also shows that the effective delivery of an intervention to successfully address a fundamental and persistent problem is possible using existing resources; however, it requires a commitment of focus and energy over considerable time.

Social implications

The approach and findings helps seniors to age in place in a rural context. It shows feasibility of delivering a practical intervention in the rural setting through the health care infrastructure of home care.

Originality/value

Apart from the rural context, the study was innovative at many levels. Specifically, this intervention addressed a significant health issue (functional capacity, falls and injuries), involved frail rural seniors (often hard to reach through community-based programs), provided a feasible intervention (multiple component exercise program), used existing infrastructure (e.g. home care), and espoused community development principles (active involvement of community partners, researchers, and trainees). As well, the study had built-in mechanisms for monitoring and support through the involvement of home service workers who received training. This approach created a strong research to practice connection (another innovation) and was critical for the credibility of the investigation, as well as the sustainability of the intervention. Another innovation was the inclusion of a population health perspective as the study framework. From the population health perspective, this research addressed several determinants of health in rural and urban areas that include: physical environment (intervention within people’s home and rural context), social environment and social support networks (through existing infrastructures of home support workers), health services (availability of health promotion strategy delivered through the health care system) and personal health practices and coping skills (exercise).
