Multi-System Physical Exercise Intervention for Fall Prevention and Quality of Life in Pre-Frail Older Adults: A Randomized Controlled Trial

Effects of multicomponent exercise on frailty status and physical function in frail older adults: A meta-analysis and systematic review

OBJECTIVES

The study aimed to carry out a systematic review and meta-analysis to explore the effects of multicomponent exercise on frailty status and physical function in frail older adults.

DESIGN

A systematic review and meta-analysis.

SETTING AND PARTICIPANTS

Older adults aged ≥60 years diagnosed with frailty using the Frailty Assessment Tool.

METHODS

PubMed, EMBASE, Web of Science, Cochrane Library, CNKI, and Wanfang were searched from inception to March 10, 2024. Two reviewers independently screened and selected the publications, extracted the data, and assessed risk of bias. This study included randomized controlled trials and quasi-experimental designs. Review Manager 5.4 was used for data analysis.

RESULTS

Twenty-eight randomized controlled trials with 4857 older adults were included. Multicomponent exercise significantly improved frailty status (SMD = -1.40, 95 % CI:-2.05 to -0.75, P < .05) and had a significant impact on physical function (muscle strength: SMD = 0.31, 95 % CI: 0.01-0.61, P < .05; gait speed: SMD = 0.27, 95 % CI: 0.02-0.52, P < .001; balance: SMD = 0.27, 95 % CI: 0.05-0.49, P = .02; Short Physical Performance Battery [SPPB]: SMD = 1.03, 95 % CI: 0.65-1.42, P < .001; and Timed Up and Go [TUG]: SMD = -3.05, 95 % CI: -3.90 to -2.19, P < .001). Subgroup analysis suggested that a 12-week duration is optimal for multicomponent exercise interventions, demonstrating significantly greater effectiveness in hospital compared with out-of-hospital.

CONCLUSIONS

Multicomponent exercise intervention can improve frailty status in older adults and promote enhancement of physical functional abilities (muscle strength, gait speed, balance, SPPB, and TUG). Therefore, a possible protective effect of multicomponent exercise in frailty older adults is suggested.

Effect of multicomponent exercise intervention in community dwelling frail elderly: A systematic review and meta-analysis

OBJECTIVE

To assess the impact of multicomponent exercises on physical functions of frail elderly in communities, evaluating their effect on muscle strength, balance, and endurance, and their influence on quality of life.

METHOD

PubMed, Embase, Cochrane, and Web of Science were searched to collect relevant randomized controlled trials. The search cutoff date was January 24, 2024. Included studies met pre-specified inclusion and exclusion criteria. Data analysis was performed using Revman 5.4 and Stata 15.0 software.

RESULT

This analysis included 19 studies. After 12 weeks, the multicomponent exercises significantly enhanced participants' performance in various physical function assessments. Specifically, in the Timed Up and Go Test, the exercise group showed a significant reduction in time [SMD = -0.86 (95 % CI: -1.40 to -0.33)]. In the Short Physical Performance Battery, interventions shorter than 6 weeks significantly increased scores [SMD = 1.01 (95 % CI: 0.64 to 1.37)], and those longer than 6 weeks showed improvements [SMD = 0.53 (95 % CI: 0.26 to 0.80)]. Muscle strength also improved, with handgrip strength and knee extensor strength enhancements [SMD = 0.93 (95 % CI: 0.27 to 1.59); SMD = 0.72 (95 % CI: 0.24 to 1.20)]. However, there was no statistically significant difference in walking speed between the groups [SMD = 0.04 (95 % CI: -0.33 to 0.40)].

CONCLUSION

Although multicomponent exercises significantly improve muscle strength, balance, and endurance in frail elderly individuals, there is no conclusive evidence of their effect on enhancing quality of life or long-term health outcomes. Further research is needed to explore the specific impacts of different types and intensities of exercises on this population.

[Long-term effects of an assets-based, co-created physical activity intervention on health-related quality of life in older adults]

PURPOSE

The purpose of this study is to examine the long-term effects of a programme called Ser Mayor, un RETO («Being Older, a Challenge») aimed at improving quality of life in older adults over 60 living in the community.

METHODS

This programme used co-design principles to create sustainable opportunities to improve quality of life, connecting with the community, and empowering older adults to take responsibility for their own health. Ser Mayor, un RETO was based on Bronfenbrenner's bio-social-ecological perspective and the health assets model. Its design was complemented with leisure education and physical activity promotion-based guidelines, identified in the scientific literature. The study design was quasi-experimental, with control group, and was conducted over a period of 20-months (September 2017 to June 2019) in several municipalities near the city of Zaragoza (Spain), with the participation of 213 older adults (n=120 experimental group and n=93 control group). Data were analysed using generalised linear mixed models controlling for age and gender of participants and accounting for initial differences between groups in the study outcomes.

RESULTS

The results indicate that the experimental group experienced an improvement in levels of quality of life relative to the control group, which was sustained over the study period, especially in several physical dimensions of quality of life: physical function (P=.014), physical role (P=.027), physical component summary (P=.022) and in emotional role (P=.033).

CONCLUSION

The Ser Mayor, un RETO programme had a positive effect on the quality of life of older adults, showing potential for sustainability of its effects and for the service providers to develop a sense of ownership over the programme.

Associations between modifiable risk factors and frailty progression among individuals with pre-frailty

BACKGROUND

In the context of the present global aging phenomenon, the senior population and pace of aging in China have emerged as prominent issues on the worldwide stage. Frailty, a complicated condition that is closely linked to the clinical syndrome of advancing age, poses a considerable health risk to older individuals. Frailty status was assessed by the frailty index (FI) ranging from 0 to 1, pre-frailty was defined as >0.10 to <0.25, and frailty was defined as ≥0.25. To look at the connection between modifiable risk factors and frailty progression among individuals in the pre-frailty population.

METHODS

Using pre-frailty patients as characterized by the 32-frailty index, the study focused on middle-aged and elderly persons from China and ultimately recruited 5,411 participants for analysis. The relationship between modifiable factors and changes in pre-frailty status throughout follow-up was investigated. Modifiable factors were body mass index (BMI), abdominal obesity, smoking status, alcohol use, and sleep status. We employed logistic regression to examine the relationships between modifiable risk factors and changes in pre-frailty status, as well as the associations between modifiable factors scores and the corresponding pre-frailty progression. Additionally, we generated the modifiable factors scores and examined how these related to modifications in the pre-frailty stage.

RESULTS

In this study, after a mean follow-up of 6 years, (OR = 0.59, 95%CI: 0.48-0.71) for BMI ≥ 25 kg/m2 and (OR = 0.74, 95%CI: 0.63-0.89) for concomitant abdominal obesity were significantly associated with lower reversal to a healthy state; (OR = 1.24, 95%CI:1.07-1.44) and (OR = 1.25, 95%CI: 1.10-1.42) for the group that negatively progressed further to frailty were significantly associated with increased frailty progression profile. Subsequently, investigation of modifiable factor scores and changes of pre-frailty status found that as scores increased further, frailty developed (OR = 1.12, 95%CI:1.05-1.18), with scores of 3 and 4 of (OR = 1.38, 95%CI: 1.08-1.77) and (OR = 1.52, 95%CI:1.09-2.14). Finally, we also performed a series of stratified analyses and found that rural unmarried men aged 45 to 60 years with less than a high school degree were more likely to develop a frailty state once they developed abdominal obesity.

CONCLUSION

In pre-frailty individuals, maintaining more favorable controllable variables considerably enhances the chance of return to normal and, conversely, increase the risk of progressing to the frailty.

A 3 month nutrition and exercise program improved hallux strength among senior daycare center users in Korea: a cluster randomized controlled trial

Introduction

With a growing aging population, the focus on the health and well-being of older adults, especially in preventing falls, becomes crucial. This 3 month study, initiated in July 2022, aimed to assess the impact of a nutrition and exercise program in senior daycare centers in Chuncheon, South Korea.

Methods

A 3 month study, beginning in July 2022, included 204 older adults from 10 senior daycare centers in Chuncheon, South Korea. Randomly assigned to intervention or control groups, the intervention involved nutrition, daily toe exercises, or both. Control centers received interventions post-measurements. Pre- and post-intervention analyses used paired t-tests and multiple linear regression, assessing metrics like toe grip strength for significance. While 204 were initially enrolled, the analysis included 151 participants due to dropouts.

Results

Participants, with a mean age of 83.3 years (43.1% aged ≥ 85 years), exhibited mild to moderate cognitive impairment and multiple chronic illnesses. Health data indicated that 37.3% were obese, and the average BMI was 24.0 kg/m2. Both the intervention and control groups showed significant improvements in toe grip strength post-intervention. Specifically, the exercise-only and combined exercise-nutrition groups demonstrated significant differences in hallux strength compared to the control group after adjusting for age and gender.

Conclusion

The study showed that a basic nutrition and exercise program increased toe strength in older adults with chronic diseases, including mild cognitive impairments. This intervention holds potential to prevent muscle strength decline and reduce fall risks in older individuals. As the first of its kind in Korean senior daycare centers, it emphasizes the need for future research and standardized programs for senior daycare users.

Community-based exercises improve health status in pre-frail older adults: A systematic review with meta-analysis

BACKGROUND

Pre-frailty is associated with increased healthcare utilization. Over the past decade, public health interventions such as community-based exercises to target pre-frailty have been increasingly studied. However, the effects of community-based exercises on clinical outcome measures amongst community-dwelling older adults with pre-frailty remain unclear. This review aims to better understand the effects of community-based exercise on physical function, cognition, quality of life and frailty status in community-dwelling pre-frail older adults. A secondary objective was to investigate the optimal exercise parameters on clinical outcomes.

METHODS

Searches of MEDLINE, CINAHL, Google Scholar and Web of Science databases were conducted. Articles were included if they were randomized controlled trials (RCTs), and excluded if the participants consist of less than 50% pre-frail community-dwelling older adults. Meta-analyses (where possible) with either a fixed- or random- effect(s) model, standardized mean difference (SMD), odds ratio (OR) and tests of heterogeneity were performed. Multivariable meta-regression was performed to identify predictors of statistically significant outcome measures. The risk of bias was assessed using the modified Cochrane Risk-of-Bias tool.

RESULTS

Twenty-two RCTs with 900 participants in the experimental group and 1015 participants in the control group were included. When compared to minimal intervention, community-based exercises significantly improved lower limb strength (10 RCTs, 384 participants in the experimental group and 482 participants in the control group) with SMD 0.67 (95% CI 0.29 to 1.04), and lower limb function (5 RCTs, 120 participants in the experimental group and 219 participants in the control group) with SMD 0.27 (95% CI 0.03 to 0.51). Those who have received community-based exercises were more likely to reverse from pre-frailty to healthy state (OR = 2.74, 95% CI 1.36 to 5.51) (6 RCTs, 263 participants in the experimental group and 281 participants in the control group). The frequency of exercise sessions was a significant predictor of the effect size for gait speed (P<0.05).

CONCLUSIONS

Community-based exercise intervention is superior to minimal intervention for improving health status in pre-frail older adults. This has implications on the implementation of community-based exercise intervention by healthcare providers and policymakers.

The Association Between Postural Sway and Preclinical Alzheimer Disease Among Community-Dwelling Older Adults

BACKGROUND

It is unknown whether older adults with preclinical Alzheimer disease (AD) experience changes in postural sway compared with those without preclinical AD. The purpose of this study was to understand the effect of dual tasking on standing balance, or postural sway, for people with and without preclinical AD.

METHODS

A cross-sectional analysis of baseline data from a longitudinal cohort study. Participants were cognitively normal older adults with and without preclinical AD. Postural sway (path length) was tested using a force plate under standard and dual task balance conditions. Dual task cost (DTC) was calculated to examine performance change in balance conditions. Logistic regression models were used to predict preclinical AD status as a function of DTC.

RESULTS

203 participants (65 preclinical AD+) were included. DTC for path length was significantly greater for participants with preclinical AD (DTC path length mean difference 19.8, 95% CI 2.6-37.0, t(201) = 2.29, p = .024). Greater DTC was significantly associated with increased odds of having preclinical AD (adjusted odds ratio for a 20-unit increase in DTC 1.16, 95% CI 1.02-1.32).

CONCLUSIONS

Older adults with preclinical AD are more likely to demonstrate significantly greater DTC in postural sway than those without preclinical AD. Dual tasking should be integrated into balance and fall risk assessments and may inform early detection of preclinical AD.

Implementing Tai Chi Exercise in Long-Term Care to Reduce Falls

BACKGROUND

Falls are a frequent occurrence in older adults in long-term care facilities.

LOCAL PROBLEM

At our long-term care facility, the percentage of patients who fell increased from 45% in 2021 to 68% in 2022, indicating a need for an evidence-based solution.

METHODS

We used an evidence-based quality improvement framework to pilot a tai chi exercise program.

INTERVENTIONS

Residents were invited to participate in the Tai Ji Quan: Moving for Better Balance program for 12 weeks. Classes were 30 minutes long and included a 5-minute warm-up and 5-minute cooldown.

RESULTS

Seventy-five residents participated in the tai chi program. There was a significant 32.3% reduction in falls ( P =.001). Residents' fall risk scores decreased 14% ( P < .001).

CONCLUSIONS

Implementing a tai chi exercise project may affect falls and decrease the overall fall risk.

Acceptability, feasibility, and effectiveness of WE-SURF™: a virtual supervised group-based fall prevention exercise program among older adults

Conducted physically, supervised group-based falls prevention exercise programs have demonstrated effectiveness in reducing the risk of falls among older adults. In this study, we aimed to assess the acceptability, feasibility, and effectiveness of a virtual supervised group-based falls prevention exercise program (WE-SURF™) for community-dwelling older adults at risk of falls.

METHOD

A preliminary study utilizing virtual discussions was conducted to assess the acceptability of the program among six older adults. Effectiveness was evaluated in a randomized controlled feasibility study design, comprising 52 participants (mean age: 66.54; SD: 5.16), divided into experimental (n = 26) and control (n = 26) groups. The experimental group engaged in a 6-month WE-SURF™ program, while the control group received standard care along with a fall's prevention education session. Feasibility of the intervention was measured using attendance records, engagement rates from recorded videos, dropouts, attrition reasons, and adverse events.

RESULTS

Preliminary findings suggested that WE-SURF™ was acceptable, with further refinements. The study revealed significant intervention effects on timed up and go (TUG) (η2p:0.08; p < 0.05), single leg stance (SLS) (η2p:0.10; p < 0.05), and lower limb muscle strength (η2p:0.09; p < 0.05) tests. No adverse events occurred during the program sessions, and both attendance and engagement rates were high (> 80% and 8/10, respectively) with minimal dropouts (4%). The WE-SURF™ program demonstrated effectiveness in reducing the risk of falls while enhancing muscle strength and balance.

CONCLUSION

In conclusion, WE-SURF™ was demonstrated to be an acceptable, feasible, and effective virtual supervised group-based exercise program for fall prevention in community-dwelling older adults at risk of falls. With positive outcomes and favourable participant engagement, WE-SURF™ holds the potential for wider implementation. Further research and scaling-up efforts are recommended to explore its broader applicability. (Registration number: ACTRN 12621001620819).

A novel score for predicting falls in community-dwelling older people: a derivation and validation study

BACKGROUND

Early detection of patients at risk of falling is crucial. This study was designed to develop and internally validate a novel risk score to classify patients at risk of falls.

METHODS

A total of 334 older people from a fall clinic in a medical center were selected. Least absolute shrinkage and selection operator (LASSO) regression was used to minimize the potential concatenation of variables measured from the same patient and the overfitting of variables. A logistic regression model for 1-year fall prediction was developed for the entire dataset using newly identified relevant variables. Model performance was evaluated using the bootstrap method, which included measures of overall predictive performance, discrimination, and calibration. To streamline the assessment process, a scoring system for predicting 1-year fall risk was created.

RESULTS

We developed a new model for predicting 1-year falls, which included the FRQ-Q1, FRQ-Q3, and single-leg standing time (left foot). After internal validation, the model showed good discrimination (C statistic, 0.803 [95% CI 0.749-0.857]) and overall accuracy (Brier score, 0.146). Compared to another model that used the total FRQ score instead, the new model showed better continuous net reclassification improvement (NRI) [0.468 (0.314-0.622), P < 0.01], categorical NRI [0.507 (0.291-0.724), P < 0.01; cutoff: 0.200-0.800], and integrated discrimination [0.205 (0.147-0.262), P < 0.01]. The variables in the new model were subsequently incorporated into a risk score. The discriminatory ability of the scoring system was similar (C statistic, 0.809; 95% CI, 0.756-0.861; optimism-corrected C statistic, 0.808) to that of the logistic regression model at internal bootstrap validation.

CONCLUSIONS

This study resulted in the development and internal verification of a scoring system to classify 334 patients at risk for falls. The newly developed score demonstrated greater accuracy in predicting falls in elderly people than did the Timed Up and Go test and the 30-Second Chair Sit-Stand test. Additionally, the scale demonstrated superior clinical validity for identifying fall risk.

Effects of physical training on depression and related quality of life in pre-frail and frail older adults: a systematic review and meta-analysis

OBJECTIVES

To investigate the effects of physical training on depression and related quality of life in pre-frail and frail individuals.

DESIGN

A systematic review and meta-analysis.

PARTICIPANTS

Pre-frail and frail older adults.

METHODS

Five electronic databases, including PubMed, Cochrane, Medline, CINAHL, and Wiley were searched through December 2023. Randomized controlled trials (RCT) comparing physical training with usual care, health education, or light-intensity exercise were included. Outcomes included depression and depression-related quality of life. The quality of the included studies was assessed using Physiotherapy Evidence Database (PEDro) score, and the Cochrane Risk of Bias Tool was used to assess the risk of bias. Meta-analysis was performed using the RevMan5.4. The certainty of the evidence was evaluated by The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach.

RESULTS

Ten articles with 589 participants met the inclusion criteria and were included. The pooled analysis indicated that depression (SMD = -0.55, 95%CI = -0.92, -0.17, p = 0.004) and mental health status in life (SMD = 1.05, 95%CI = 0.59, 1.50, p < 0.00001) improved significantly in the experimental group. The results of subgroup analysis revealed that the beneficial effects of physical training were significant only in frail older adults but not in pre-frail older adults.

CONCLUSION

This meta-analysis showed that the positive effects of physical training on depression and related quality of life were evident for people with frailty. However, no positive results were observed in pre-frail older adults, indicating the need for further investigation in this subgroup.

Effectiveness of a sensorimotor exercise program on proprioception, balance, muscle strength, functional mobility and risk of falls in older people

Introduction

Sensory systems provide the necessary information for a motor response to be provided. In this sense, the objective of this study is to evaluate the effectiveness of a sensorimotor exercise program on proprioceptive acuity, balance, muscle strength, functional mobility and risk of falls in institutionalized elderly.

Methodology

56 participants (84.6 ± 8.4 years) were randomly distributed between the control (CG, n = 28) and intervention groups (IG, n = 28). The CG performed a protocol based on warm-up, muscle strengthening and warm down and the IG performed the same intervention, with the addition of sensorimotor exercises. Joint Position Sensation (JPS) was evaluated in both limbs at angles of 20° and 45°, balance, functional mobility, fear of falling in the elderly and muscle strength of quadriceps, hamstrings, adductors and abductors in both limbs, before and after the 12 weeks of intervention.

Results

Both groups showed gains in muscle strength. When analyzing functionality through Timed Up and Go (TUG), before and after for each group separately, both showed a significant difference (CG p = 0.002; IG p < 0.001). For the Short Physical Performance Battery (SPPB) variable, there were significant differences in IG in balance (p < 0.001), gait speed time (s) (p = 0.004) and sit-to-stand (p = 0.002). In JPS, significant differences were recorded for Absolute Error 45° Non-Dominant (p = 0.045) and Relative Error 45° Non-Dominant (p = 0.045) in the CG and Relative Error 45° Non-Dominant for IG (p = 0.018). In the Falls Efficacy Scale International (FES-I) variable there were significant improvements in the CG (p = 0.006) and in the GI (p = 0.002). However, only IG showed significant improvements (p = 0.013) for Activities-Specific Balance Confident (ABC) in a comparison between before and after the 12-week research period. When comparing the differences verified with the intervention between CG and IG, only balance SPPB (p < 0.001) and sit-to-stand SPPB (p = 0.022) showed significant values.

Conclusion

He effectiveness of sensorimotor exercises provides balance gain in the elderly (p < 0.001) and positively impacts their confidence (p = 0.013) when performing their duties. It is concluded that the protocol presented in its different levels of difficulty is effective and important for the quality of life of the institutionalized sedentary elderly.

Physical-activity interventions to reduce fear of falling in frail and pre-frail older adults: a systematic review of randomized controlled trials

BACKGROUND

Frailty in older adults leads to progressive deterioration of their physical condition and makes them prone to develop Fear of Falling (FoF). Physical-activity interventions appear to be effective in managing the components of frailty but there is no clear evidence to determine whether physical-activity may affect FoF in frail and pre-frail older adults.

OBJECTIVE

Τhis systematic literature review aims to synthesize evidence on the relationship between the physical interventions to ameliorate balance, strength, and mobility and FoF reduction in frail and pre-frail older adults.

METHODS

Studies assessing physical-activity interventions for frail and pre-frail older adults aged 60 years and older were identified in English through searches in PubMed, ScienceDirect, and Cochrane Central Register of Controlled Trials databases till February 2023. Study quality was assessed, and a qualitative synthesis of results was performed.

RESULTS

A total of 13 studies published were included. All of them were Randomized Control Trials and the most frequent assessment tool used to assess FoF (10 of 13 studies) was the Fall Efficacy Scale-International (FES-I). Six studies were assessed as having a low risk of bias. Cumulatively, the findings of this review indicate that physical-activity interventions are effective in reducing the FoF of frail and pre-frail older adults.

CONCLUSION

The results are encouraging and recapitulate the positive role of physical interventions in FoF reduction. However, future research would benefit from longer follow-up periods, longer intervention duration, and participation of interdisciplinary teams.

Strength in arms: empowering older adults against the risk of slipping and falling-a theoretical perspective

Background

Slips and falls are a serious health concern, particularly among older adults. Current physical therapy protocols strengthen the legs to improve balance. However, arm movements help maintain balance during a slip incident. Understanding how arm movements improve balance may help clinicians develop more comprehensive fall-prevention protocols to improve patient outcomes.

Clinical question

What limitations exist in current fall prevention protocols for reducing falls in older adults during slip incidents, and what new strategies can enhance these outcomes?

Key results

Slip incidents often result in a sideways loss of balance, leading to hip fractures in older adults. During a slip, the legs do not produce sideways motion and are less effective in regaining balance in this direction. Contrary, the arms produce 100 + degrees of abduction and this motion reduces falls by 200%+ during a slip incident. Notably, older adults exhibit 35.7% decreased arm abduction acceleration responses compared to younger adults during a slip incident. This delay may be attributed to age-related decreases in type II fibers of the deltoid. High-velocity and ballistic training have been shown to improve the proportion and size of type II fibers as well as improve fall outcomes when focused on the lower extremities.

Clinical application

Therefore, I propose incorporating arm abductor training, alongside leg exercises, as a cost-effective and low-risk intervention to enhance the slip responses in older adults. In light of its minimal risk and considerable potential benefits, starting arm abductor exercises with older adults is a sensible move.

Walking to Prevent Fear of Falling Among Community-Dwelling Older Adults: A Scoping Review

The current review sought to identify and synthesize the evidence on available interventions that include walking and their impact on fear of falling (FOF) among community-dwelling older adults without cognitive impairment. A 10-year search was conducted (January 2012 to January 2022) in two peer-reviewed databases. A total of 116 articles were identified, and 22 articles were reviewed. Most studies included multicomponent walking interventions, such as walking and another type of intervention or exercise. Among the different questionnaires to assess FOF, the Falls Efficacy Scale-International was the most used in 77.3% (n = 17) of studies. In addition to walking, interventions to reduce FOF mainly included balance training, lower extremity strengthening, cardio or aerobic exercises, or a combination of these exercises. Further research is needed to evaluate the impact of unidimensional walking interventions, as well as those that incorporate psychological and technological elements targeted to FOF prevention and management.

A Physically Active Lifestyle Can Protect against Age-Related Decline in Ankle Proprioception

This study examined whether physically active middle-aged (50-64 years) and older adults (65-80 years) demonstrate age-related ankle proprioceptive decline relative to younger counterparts. Empirical data indicate that ankle proprioception declines with aging and such sensory decline negatively affects balance. Using a passive motion apparatus, we employed a psychophysical forced-choice paradigm in which the ankle was passively plantarflexed to a reference position (15° or 25°) and a comparison position that was always smaller than the reference. Subsequently, participants indicated which position was more plantarflexed. As outcome measures of ankle position sense acuity, a just-noticeable-difference (JND) threshold and the uncertainty area (UA) were derived from the psychometric stimulus-response difference function for each participant. The JND threshold is a measure of proprioceptive bias and UA constitutes a measure of precision. The main results are: First, at the 15° reference, most middle-aged (74%) and older adults (71%) had thresholds within the range of the young adults. The respective median JND threshold of young adults was statistically lower when compared to both older groups. Second, no differences between age groups were observed at the 25° reference. Third, no age-related differences were found for UA at either reference. These data indicate that physically active aging adults may be spared from age-related decline in ankle position sense and that age-related differences emerge for small ankle displacements. The findings underscore the importance of remaining active during aging.

Trends of fall-related and other fatal injuries in older adults in Finland between 1998 and 2020

BACKGROUND

The number of falls and fall-related injuries will likely increase as the number of older adults expands. Increases in total deaths due to falls have been observed over Europe. Less is known about other injuries leading to death.

To examine the incidence trends of fall-related and other fatal injuries among adults aged 65 or older in Finland.

METHODS

We analyzed open data from Statistics Finland's register on the causes of death of those aged ≥65 collected between 1998 and 2020 yielding a total of 32 150 deaths due to injury using Poisson regression and distributional comparisons chi-squared tests.

RESULTS

The most common injuries leading to death among people aged ≥65 in Finland were fall related. There has been an increase in the absolute number of fall-related and other injuries, but when adjusting for person-years in population, a significant decrease can be observed. The crude rates of deaths from fall-related injuries among males annually increased 1.1-4.4% from 1998 to 2020, while the changes in rates among females ranged between -2% and 1.6%. The crude rates of other injuries ranged between -0.5% to +3.8%. Recently (2018-20), nearly 40% of the cases in males and 25% of cases in females were not fall related but comprised other types of injury mechanisms such as traffic, poisoning and drowning.

CONCLUSION

Strengthening the implementation of preventive strategies is essential to prevent injuries. To reduce injury-related mortality and disability, improvement of acute and post-acute care for injured older patients is warranted.

Physical exercise habits are related with reduced prevalence of falling among elderly women in China

BACKGROUND

Although some studies have examined the association between exercise and falls, most have focused on specific exercises, and the results have been inconsistent. In addition, there is a lack of evidence on elderly Chinese women who have different living and exercise habits compared to those in other countries. Therefore, this study aimed to investigate whether physical exercise is associated with falls in elderly Chinese women.

METHODS

This cross-sectional study included 1429 elderly Chinese women with a mean age of 69.2 years. Information on physical exercise habits and fall experiences was collected using a self-report questionnaire. Logistic regression models were used to analyze the association between physical exercise habits and falls.

RESULTS

The results showed that 15% participants had a fall in the past year. After adjusting for confounding factors, the odd ratios (ORs) and 95% Confidence Intervals (CIs) for fall experiences across categories of exercise frequency were as follow: 1 (reference) for no exercise behavior, 0.50 (0.29, 0.85) for exercise 1 to 5 times a week, and 0.37 (0.25, 0.55) for exercise more than 6 times a week. Furthermore, the ORs (95% CIs) across categories of exercise insistence were 1 (reference) for less than 1 year, 0.78 (0.37, 1.65) for 1 to 3 years, and 0.38 (0.20, 0.74) for more than 3 years. In terms of exercise duration, the ORs (95% CIs) for < 1 h/day, 1-2 h/day, and > 2 h/day were 1 (reference), 0.85 (0.53, 1.36), and 2.80 (1.30, 6.05). Unlike other variables, longer exercise duration was associated unfavorably with falls.

CONCLUSION

Physical exercise habits were associated with falls in elderly Chinese women. Keeping a proper exercise habit may contribute to lower risk of falling in elderly women.

Efficacy of standard operating procedures for fall protection in hospitalized patients with schizophrenia

Fall-related injury is the most common cause of functional disability and mortality in the older population. Falls in patients with schizophrenia are one of the major concerns in psychiatric hospitals. This study aimed to examine the impact of standardized operating procedures (SOP) on falls in veterans with schizophrenia. Veterans with schizophrenia were allocated to the control group (n = 345) and to the fall protection standardized operating procedures (FP-SOP) group (n = 342). Patients in the control group were given routine nursing for falls, and patients in the FP-SOP group were intervened with FP-SOP plus routine nursing. All patients were observed for one year. The study methods comply with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. We found a fall rate of 1.5% in the FP-SOP group and 4.6% in the control group, with a significant difference in the fall rate between the two groups. In addition, the difference in patient satisfaction between the two groups was statistically significant. Our findings suggest that FP-SOP is an effective strategy for fall prevention in psychiatric hospitals.

Exploring factors influencing health-related quality of life in adult females with injuries: a cross-sectional nationwide study

Objectives

This study aimed to identify the types of injury experiences affecting adult females and the associations between injury experiences and health-related quality of life.

Methods

This study used a secondary analysis of cross-sectional data from the Korea National Health and Nutrition Examination Survey, which employed a stratified multistage probability sampling design to obtain nationally representative data. Health-related quality of life was measured with the EuroQol Five-Dimension and consisted of mobility, self-care, usual activity, pain/discomfort, and anxiety/depression.

Results

Among women aged 19-64, the prevalence of injury experience was 5.9%. Women's injury experience varied by age, subjective health perception, menstruation details, osteoporosis status, and osteoarthritis status. The following injury experience-related factors were significantly associated with health-related quality of life: self-care (odds ratio [OR] = 0.32, 95% confidence interval [CI]: 0.17-0.60), usual activity (OR = 0.43, 95% CI: 0.27-0.70), and pain/discomfort (OR = 0.56, 95% CI: 0.44-0.72).

Conclusion

Health-related quality of life among adult women was significantly associated with injury experience. The results of this study highlight risk factors for injury that are associated with aging, such as menopause, osteoporosis, and osteoarthritis. Accurate assessments of pain and discomfort, as well as daily activities, are essential for designing effective interventions for injured women. Tailored training and education can promote self-management and improve outcomes for recovery.

Telerehabilitation in Low-Resource Settings to Improve Postural Balance in Older Adults: A Non-Inferiority Randomised Controlled Clinical Trial Protocol

Background: Several exercise methods with virtual reality devices have been used in treatments for older adults and patients with neurodegenerative diseases, although the mechanisms continue to be elucidated. The aim of this study is to establish the feasibility and effectiveness of a rehabilitation programme using low-cost virtual reality aimed at improving postural balance in older adults. It also seeks to compare low-cost virtual reality under two delivery modalities, telerehabilitation (TR) in elderly centres and face-to-face (FtF) in rehabilitation centres. Methods: The study is set up as a non-inferiority two-arm parallel triple-blind randomised controlled clinical trial. Sixteen persons aged 65 to 75-years-old will be included. Eighteen Wii therapy sessions (25-30 min) will be provided through both FtF (control group, n = 8) and TR (exposure group, n = 8), both with a Nintendo Wii balance board. Data will be collected at baseline (week 0), during the Wii therapy sessions (weeks 2, 4, and 6), and during the follow-up (weeks 8 and 10). The primary outcome will be the area of centre-of-pressure (CoP) sway; secondary outcomes will be medial-lateral and anterior-posterior velocity and standard deviation of CoP; and tertiary outcomes will be clinical measures: single-leg stand, timed up-and-go tests, Barthel Index, and Tinetti's scale. Statistical analyses will be performed using SPSS 20.00 for Windows. The trial adheres to the Declaration of Helsinki and the Chilean laws of rights and duties of the patient and research in humans. Ethical approval was obtained from the Ethics Committee of the University of Talca. Written informed consent will be obtained from participants. Discussion: In this trial, older adults from a Chilean city with a large rural and underserved population share will be included to test the feasibility and effectiveness of a rehabilitation programme using low-cost VR aimed at improving postural balance to generate evidence to support decision makers generating public health policy.

Effectiveness of exercise interventions on fall prevention in ambulatory community-dwelling older adults: a systematic review with narrative synthesis

Objective

To present a systematic review of randomized controlled trials which summarizes the effects of community-based resistance, balance, and multi-component exercise interventions on the parameters of functional ability (e.g., lower extremities muscle strength, balance performance and mobility).

Methods

This PROSPERO-registered systematic review (registration no. CRD42023434808) followed the PRISMA guidelines. Literature search was conducted in Cochrane, Embase, Ovid Medline, PEDro, Pubmed, Science Direct, Scopus and Web of Science. We included RCTs that investigated the following interventions: lower extremity strengthening, balance and multi-component exercise interventions on ambulatory community-dwelling adults aged ≥65 years.

Results

Lower extremity strengthening exercises revealed significant effects on the strength of lower extremity, balance outcomes and mobility. Balance exercises reduce the rate of injurious falls, improve static, dynamic and reactive balance, lower extremity strength as well as mobility. Multi-component exercise training reduces medically-attended injurious falls and fallers, incidence of falls, fall-related emergency department visits as well as improves mobility, balance, and lower extremity strength.

Conclusion

Physical exercises are effective in improving the components of balance, lower extremity strength, mobility, and reducing falls and fall-related injuries. Further research on fall prevention in low-income countries as well as for older adults in vulnerable context is needed.

Digital assistance systems in the field of incontinence care for individuals in need of long-term care (EASY): study protocol of a stratified randomised controlled trial

BACKGROUND

In general, urinary and faecal incontinence is a multifaceted problem that is associated with increasing burdens for those affected, a massive impairment of quality of life and economic consequences. Incontinence is associated with a high level of shame, which in particular reduces the self-esteem of those being incontinent and leads to additional vulnerability. Those affected by incontinence often perceive incontinence and the care they receiveas humiliating, hence they can no longer control their own urination; nursing care and cleansing support then lead to additional dependency. People with incontinence in need of care not uncommonly experience a poor communication and many taboos surrounding the issue as well as the use of force when incontinence products are changed.

AIMS AND METHODS

This RCT aims to validate the benefits of using a digital assistance system to optimise incontinence care and to enable statements concerning the effect of the assistance technology on nursing and social structures and processes as well as on the quality of life from the perspective of the person in need of care. In a two-arm, stratified, randomised, controlled interventional study, primarily incontinence-affected residents of four inpatient nursing facilities will be examined (n = 80). One intervention group will be equipped with a sensor-based digital assistance system, which will transmit care-related information to the nursing staff (via smartphone). The collected data will be compared to the data of the control group. Primary endpoints are falls occurring; secondary endpoints are quality of life and sleep, sleep disturbances and material consumption. In addition, nursing staff (n = 15-20) will be interviewed regarding the effects, experience, acceptance and satisfaction.

DISCUSSION

The RCT aims at the applicability and effect of assistance technologies on nursing structures and processes. It is assumed that, amongst other things, this technology may lead to a reduction of unnecessary checks and material changes, an improvement of life quality, an avoidance of sleep disturbances and thus an improvement of sleep quality as well as to a reduced risk of falling for people with incontinence in need of care. The further development of incontinence care systems is of social interest as this offers the prospect of improving the quality of care for nursing home residents with incontinence.

TRAIL REGISTRATION

Approval of the RCT is granted by the Ethics Committee at the University of Applied Sciences Neubrandenburg (Reg.-Nr.: HSNB/190/22). This RCT is registered at the German Clinical Trials Register on July 8^th, 2022, under the identification number DRKS00029635.

Associations between frailty, sociodemographic characteristics and quality-of-life among community-dwelling older adults: A cross-sectional study

AIM

To explore the quality-of-life among community-dwelling older adults in China and to examine the associations between frailty, sociodemographic characteristics and quality-of-life.

DESIGN

A cross-sectional correlational study was adopted.

METHODS

Questionnaire study of 311 community-dwelling older adults using the Life Satisfaction Questionnaire and FRAIL scale.

RESULTS

Highest quality-of-life was found for the physical symptoms factor and the lowest for quality of everyday activities/fun. Frailty was associated with total quality-of-life and the physical symptoms and sickness impact factors. For total quality-of-life, the odds of being in the group with a median score or more decreased for frail older people (OR 0.30) versus non-frail and increased for those with medical insurance from employer versus basic (OR 2.30) and those doing exercise ≥30 min 3 days/week or more versus less (OR 2.12). Registered nurses caring for community-dwelling older adults should screen for and prevent frailty and encourage exercise to improve their quality-of-life.

Effects of the Implementation of an Intervention Based on Falls Education Programmes on an Older Adult Population Practising Pilates-A Pilot Study

Age brings consequent physical deterioration of body balance, strength, flexibility and agility. It has been demonstrated that daily physical activity (PA), managed by professionals, is fundamental to ageing with increased quality and to reducing the number of falls, which are a consequence of factors highlighted above. This has been most evident during the COVID-19 pandemic. The aim of this study is to determine and analyse the effects of a multidisciplinary intervention based on the Safe Fall, Safe Schools, adapted utilitarian judo (JUA) and Pilates programmes in a population of older people. After an intervention of 60 min, 2 days a week for 12 weeks, the changes produced in variables such as quality of life, balance, lower body strength, flexibility and agility were analysed. A p-value ≤ 0.05 is accepted. The data show that the intervention can help to improve quality of life, especially two of its dimensions: pain (increases 12 points) and health transition (increases 13 points). It also helped to improve balance, lower body strength, flexibility and agility to a lesser extent. It is concluded that this type of intervention has positive effects for the sample in all the variables mentioned above.

Effects of a Physical Activity Program that Incorporates Exercises Targeting Balance, Strength, and Proprioception on Cognitive Functions and Physical Performance in Old Adults with Mild Cognitive Impairment

BACKGROUND

Aging often leads to cognitive function decline, sensory structure deterioration, and musculoskeletal system weakening. This impacts postural control during static and dynamic activities like walking, increasing the fall risk among the elderly. Older adults with mild cognitive impairment (MCI) face an elevated fall risk and cognitive decline, magnifying the public health concern.

OBJECTIVE

This study aimed to explore solutions by investigating the effects of a multi-component physical activity program on cognitive and motor functions in MCI patients.

METHODS

Twenty-three participants were enrolled in the study and assigned into two groups: an intervention group (n = 13; age = 85.7±5.5 years) and a control group (n = 9; age = 85±6.7 years). The study spanned two months, with participants engaging in three 60-minute weekly physical exercise sessions. The intervention focused on improving proprioception, muscle strength, and balance.

RESULTS

Results demonstrated significant enhancements in physical performance, fall risk reduction, and balance (p < 0.05). Various tests, including the timed up and go test, Unipedal Stance test, Tinetti test, Short Physical Performance Battery, and 6-minute walking test, indicated these improvements. Cognitive function was evaluated with the Mini-Mental State Examination, revealing non-significant progress (p > 0.05). Predictive models for outcomes were developed using linear regression analysis during the follow-up stage.

CONCLUSIONS

This study underscores the effectiveness of a multi-component physical activity program encompassing balance, proprioception, and muscle-strengthening exercises as a non-pharmaceutical approach in improving balance skills and playing a key role in mitigating the risk of falls among old adults with MCI.

Falls caused by balance disorders in the elderly with multiple systems involved: Pathogenic mechanisms and treatment strategies

Falls are the main contributor to both fatal and nonfatal injuries in elderly individuals as well as significant sources of morbidity and mortality, which are mostly induced by impaired balance control. The ability to keep balance is a remarkably complex process that allows for rapid and precise changes to prevent falls with multiple systems involved, such as musculoskeletal system, the central nervous system and sensory system. However, the exact pathogenesis of falls caused by balance disorders in the elderly has eluded researchers to date. In consideration of aging phenomenon aggravation and fall risks in the elderly, there is an urgent need to explore the pathogenesis and treatments of falls caused by balance disorders in the elderly. The present review discusses the epidemiology of falls in the elderly, potential pathogenic mechanisms underlying multiple systems involved in falls caused by balance disorders, including musculoskeletal system, the central nervous system and sensory system. Meanwhile, some common treatment strategies, such as physical exercise, new equipment based on artificial intelligence, pharmacologic treatments and fall prevention education are also reviewed. To fully understand the pathogenesis and treatment of falls caused by balance disorders, a need remains for future large-scale multi-center randomized controlled trials and in-depth mechanism studies.

The effectiveness of a group-based Otago exercise program on physical function, frailty and health status in older nursing home residents: A systematic review and meta-analysis

OBJECTIVES

To explore the effects of a group-based Otago exercise program (OEP) on physical function (mobility, balance, lower limb strength), frailty and health status in older nursing home residents to determine the optimal scheme and format.

METHODS

This systematic review and meta-analysis was conducted to estimate group-based OEP effects. Subgroup analysis was performed to identify the influences of the participant and intervention characteristics on the effects.

RESULTS

Twelve studies met the eligibility criteria and were included in this meta-analysis, and the overall quality was relatively high. The results showed that the group-based OEP significantly improved physical function, including mobility [SMD=-0.64, 95% CI (-0.83,-0.45), Z=6.55, p<0.001], balance [MD=4.72, 95% CI (3.54, 5.90), Z=7.84, p<0.001], lower limb strength [SMD=-1.09, 95% CI (-1.40, -0.79), Z=7.01, p<0.001]; frailty [SMD=-0.73, 95% CI (-1.01, -0.45), Z=5.13, p<0.001] and health status [SMD=0.47, 95% CI (0.20, 0.74), Z=3.44, p=0.0006]. Subgroup analysis revealed that 30-minute sessions were more beneficial for improving balance than >30-minute sessions (p=0.0004). The training was coordinated with physiotherapists, who were more skilled at improving mobility than providing health training education (p=0.04).

CONCLUSIONS

Group-based OEP is helpful for improving physical function, frailty and health status in older nursing home residents. Specifically, 30-minute sessions and coordinating with physiotherapists may be the most appropriate and effective options.

Evaluation of autonomic cardiac modulation and body composition in elderly submitted to the protocol of exercise and the gametherapy: A clinical trial protocol (SPIRIT compliant)

INTRODUCTION

Aging affects the cardiovascular system by impairing the amount and strength of cardiac pumping. Heart rate variability (HRV) is a safe parameter to assess variations in the cardiovascular system, providing data on sympathetic and parasympathetic activations.

OBJECTIVES

Our primary aim is to investigate the cardiac autonomic modulation and body composition of active older adults participating in a physical exercise protocol and gametherapy. Our secondary aim is to assess their functional capacity, cognitive function, balance, respiratory pressures, and functional autonomy.

METHOD

This randomized clinical trial will include 100 active older adults aged 60 to 80 years. The exercise group (EG) will perform 24 supervised training sessions (strength and aerobic) for 12 weeks (2 60-minutes sessions per week). The gametherapy group (GG) will exercise using gametherapy. Assessments will occur on the first week, after the 12th week, after wash out and in the end of cross over. The primary outcome will be HRV and body composition (bioimpedance). Secondary outcomes will be functional capacity (6-minute walk test), cognitive function (mini-mental state examination), risk of falls and balance (berg balance scale and timed up and go test), inspiratory and expiratory pressures (manovacuometry) and functional autonomy (functional reach test and group of Latin American development to maturity [GDLAM] protocol).

DISCUSSION

This study will provide relevant information about the effects of physical training (physical exercises and gametherapy) on HRV and other variables in active older adults.

Cost-effectiveness of miglustat versus symptomatic therapy of Niemann-Pick disease type C

BACKGROUND

Niemann-Pick disease type C (NP-C) is a progressive neurodegenerative disorder with early infantile (< 2 years), late infantile (2-6 years), juvenile (7-15 years) and adolescent (> 15 years) onset. The mainstay of therapy for NP-C patients with neurological symptoms is miglustat, a drug that may modify the course of the disease.

AIM

Our aim was to evaluate the cost-effectiveness of miglustat in comparison to symptomatic therapy in patients with NP-C in the socio-economic settings of the Republic of Serbia, an upper-middle-income European economy.

METHOD

The perspective of the Serbian Republic Health Insurance Fund was chosen for this study, and the time horizon was eighty years. The main outcomes of the study were quality-adjusted life years gained with miglustat and comparator, and direct costs of treatment. The study was conducted through the generation and simulation of the Discrete-Event Simulation model. The model results were obtained after Monte Carlo microsimulation of a sample with 1000 virtual patients.

RESULTS

Treatment with miglustat was not cost-effective when compared with symptomatic therapy and was associated with negative values of net monetary benefit regardless of the onset of neurological manifestations (- 110,447,627.00 ± 701,614.00 RSD, - 343,871,695.00 ± 2,577,441.00 RSD, - 1,397,908,502.00 ± 23,084,235.00 RSD and - 2,953,680,879.00 ± 33,297,412.00 RSD) for early infantile, late infantile, juvenile and adolescent cohorts, respectively).

CONCLUSION

When traditional pharmacoeconomic evaluation is employed, miglustat is not a cost-effective option in comparison to symptomatic therapy for the treatment of NP-C. However, given the proven efficacy of miglustat, there is a need to find ways to make this drug available to all patients with NP-C.

Epidemiology and outcomes of older trauma patients in Singapore: A multicentre study

BACKGROUND

An ageing population has caused rising trauma cases amongst older patients. Multiple comorbidities, polypharmacy and limited reserves predispose them to poorer outcomes following a traumatic event. The Comorbidity Polypharmacy Score (CPS) has been found to predict outcomes and mortality in older trauma patients, but has not been studied in Asians.

AIM

We aim to describe the epidemiological characteristics of older trauma patients and explore the association of CPS on clinical outcomes.

METHODS

We conducted a retrospective observational study using data from the trauma registries of 2 tertiary trauma centres. Patients aged 45 years and above attending the emergency departments (EDs) from January 2011 to December 2015 with traumatic injuries (Injury Severity Score [ISS] of 9 and above) were included. Demographics, clinical data including number of comorbidities and medications used were collected to calculate the CPS. Outcomes of mortality, ED disposition and hospital discharge venue were examined.

RESULTS

There were 4,522 patients (median age 70 years; males 53.8%), with majority sustaining Tier 2 injuries (ISS 9 to 15; 68.9%). Falls were the predominant mechanism for those aged above 60 years and above (76%). Median CPS was 6 (interquartile range [IQR] 1 to 11). Amongst patients 75 years and older, 56% comprised the moderate to morbid CPS groups (CPS ≥ 8). Overall mortality was 8.4%; patients above 75 years had longer median length of stay (10 versus 7.1-8.9 days in other ages). Male gender (adjusted odds ratio [aOR] 1.51; 95% confidence interval [CI] 1.12-2.02), increasing age (aOR 1.04; 95% CI 1.03-1.05), injury to abdomen (aOR 3.24; 95% CI 1.93-5.45) and severe CPS category (aOR 1.88; 95% CI 1.23-2.89) were associated with increased odds of death. Increasing age and moderate CPS category increased odds of discharge to a rehabilitation (aOR for age 1.03, 95% CI 1.02-1.04; aOR for moderate CPS 1.72, 95% CI 1.43-2.07) or long-term care facility (aOR for age 1.05, 95% CI 1.03-1.06; aOR for CPS 1.60, 95% CI 1.10-2.32).

CONCLUSION

CPS predicted mortality and discharge to a rehabilitation or care facility in this urban, ageing Asian population. Its use may aid future trauma research and needs assessments in such patients.

The Effectiveness of a Hybrid Exercise Program on the Physical Fitness of Frail Elderly

BACKGROUND

Frailty is a serious physical disorder affecting the elderly all over the world. However, the frail elderly have low physical fitness, which limits the effectiveness of current exercise programs. Inspired by this, we attempted to integrate Baduanjin and strength and endurance exercises into an exercise program to improve the physical fitness and alleviate frailty among the elderly. Additionally, to achieve the goals of personalized medicine, machine learning simulations were performed to predict post-intervention frailty.

METHODS

A total of 171 frail elderly individuals completed the experiment, including a Baduanjin group (BDJ), a strength and endurance training group (SE), and a combination of Baduanjin and strength and endurance training group (BDJSE), which lasted for 24 weeks. Physical fitness was evaluated by 10-meter maximum walk speed (10 m MWS), grip strength, the timed up-and-go test (TUGT), and the 6 min walk test (6 min WT). A one-way analysis of variance (ANOVA), chi-square test, and two-way repeated-measures ANOVA were carried out to analyze the experimental data. In addition, nine machine learning models were utilized to predict the frailty status after the intervention.

RESULTS

In 10 m MWS and TUGT, there was a significant interactive influence between group and time. When comparing the BDJ group and the SE group, participants in the BDJSE group demonstrated the maximum gains in 10 m MWS and TUGT after 24 weeks of intervention. The stacking model surpassed other algorithms in performance. The accuracy and precision rates were 75.5% and 77.1%, respectively.

CONCLUSION

The hybrid exercise program that combined Baduanjin with strength and endurance training proved more effective at improving fitness and reversing frailty in elderly individuals. Based on the stacking model, it is possible to predict whether an elderly person will exhibit reversed frailty following an exercise program.

Effects of Home-Based Nine-Square Step Exercises for Fall Prevention in Thai Community-Dwelling Older Adults during a COVID-19 Lockdown: A Pilot Randomized Controlled Study

The deterioration of muscle strength in aging has been associated with fall risks. During the COVID-19 pandemic, older adults were restricted from doing outdoor activities. This study aimed to investigate the effect of Nine-Square Step Exercises (NSSE) on improving physical performance and balance in older adults at risk of falling. We conducted an open-labelled, assessor-blinded, randomized controlled trial in 46 (aged 65-84 years) community-dwelling older adults. They were randomly assigned to an NSSE group (n = 24) instructed to perform the program for at least 45 days over 8 weeks or a control group (n = 22). The outcomes were measured by the Timed Up and Go Test (TUG), the Berg Balance Scale (BBS), the Five-Times-Sit-to-Stand test (FTSS), and hand grip strength during the baseline, 4th and 8th weeks in both groups. A mixed-effect linear regression model analysis was performed to estimate the independent effect of NSSE by the intention-to-treat over the 8-week period. The NSSE group showed significant weekly changes in BBS (β 0.57, 95% CI: 0.30, 0.84), TUG (β -0.44, 95% CI: -0.74, -0.14), and FTSS (β -0.52, 95% CI: -0.78, -0.25), demonstrating beneficial improvements in lower extremity and balance, whereas the control group did not demonstrate significant changes over time in any parameter.

Ditangquan exercises based on safe-landing strategies prevent falls and injury among older individuals with sarcopenia

Background

Sarcopenia is the age-related loss of skeletal muscle mass and function; it is a risk factor for falls among older individuals. Few studies have focused on training such individuals to adopt a safe-landing strategy that would protect them from fall-related injuries. Ditangquan is a traditional Chinese martial art comprising movements that conform to the principles of safe landing. This study aims to investigate the effectiveness of Ditangquan in preventing fall-related injuries among older individuals with sarcopenia.

Methods

A total of 70 participants (21 males and 49 females with sarcopenia) between 60 and 80 years of age were recruited from three local communities and randomly assigned to the Ditangquan exercise group (DG) or the control group (CG) in a 1:1 ratio. Three times a week for 24 weeks, both the DG and CG received an hour of conventional exercise and an hour of Ditangquan exercise based on safe landing. Primary outcomes were the modified falls efficacy scale (MFES), the number of falls, and fall injuries; the secondary outcome was the Timed Up & Go (TUG) test.

Results

The DG had significantly fewer falls (1 vs. 8, P = 0.028) and fall injuries (0 vs. 6, P = 0.025) than the CG. Furthermore, at the end of the study, the DG had a significantly improved MFES (mean difference: 32.17 scores; 95% CI: 21.32, 43.02; P <0.001) and TUGT (mean difference: −4.94 s; 95% CI: −7.95, −1.93; P = 0.002) as compared with the CG.

Conclusion

Ditangquan exercise based on the safe-landing strategy effectively improves the functional mobility of the elderly, reduces the occurrence of falls and injuries, and increases the individual's confidence in preventing falls.

Effect of a multicomponent exercise program and cognitive stimulation (VIVIFRAIL-COGN) on falls in frail community older persons with high risk of falls: study protocol for a randomized multicenter control trial

BACKGROUND

Falls represent important drivers of intrinsic capacity losses, functional limitations and reduced quality of life in the growing older adult's population, especially among those presenting with frailty. Despite exercise- and cognitive training-based interventions have shown effectiveness for reducing fall rates, evidence around their putative cumulative effects on falls and fall-related complications (such as fractures, reduced quality of life and functional limitations) in frail individuals remains scarce. The main aim of this study is to explore the effectiveness program combining an individualized exercise program and an executive function-based cognitive training (VIVIFRAIL-COGN) compared to usual care in the prevention of falls and fall-related outcomes over a 1-year follow-up.

METHODS

This study is designed as a four-center randomized clinical trial with a 12-week intervention period and an additional 1-year follow-up. Three hundred twenty frail or pre-frail (≥ 1 criteria of the Frailty Phenotype) older adults (≥ 75 years) with high risk of falling (defined by fall history and gait performance) will be recruited in the Falls Units of the participating centers. They will be randomized in a 1:1 ratio to the intervention group (IG) or the control group (CG). The IG will participate in a home-based intervention combining the individualized Vivifrail multicomponent (aerobic, resistance, gait and balance and flexibility) exercise program and a personalized executive function-based cognitive training (VIVIFRAIL-COGN). The CG group will receive usual care delivered in the Falls Units, including the Otago Exercise Program. Primary outcome will be the incidence of falls (event rate/year) and will be ascertained by self-report during three visits (at baseline, and 6 and 12 weeks) and telephone-based contacts at 6, 9 and 12 months after randomization. Secondarily, effects on measures of physical and cognitive function, quality of life, nutritional, muscle quality and psychological status will be evaluated.

DISCUSSION

This trial will provide new evidence about the effectiveness of an individualized multidomain intervention by studying the effect of additive effects of cognitive training and physical exercise to prevent falls in older frail persons with high risk of falling. Compared to usual care, the combined intervention is expected to show additive effects in the reduction of the incidence of falls and associated adverse outcomes.

Falls and Preventive Practices among Institutionalized Older People

The present study about falls among the older adult population essentially explores bio-physiological factors. In light of the complexity of the factors that cause these accidents, it is important to identify the safety and self-care practices of institutionalized older adults and their relationship with falls in order to introduce prevention measures and personalized cognitive–behavioral strategies. The objective of this study was to: (a) determine the frequency of falls and their recurrence among institutionalized older adults, and (b) to associate the occurrence of falls among institutionalized adults with or without cognitive impairment to communication and safety practices. This was a quantitative, correlational, and longitudinal study with 204 institutionalized older adults living in two long-term care facilities in Portugal. The Scale of Practices and Behaviors for Institutionalized Elderly to Prevent Falls was administered to the sample. The prevalence of falls at a 12-month follow-up was 41.6%, of which 38.3% were recurring episodes. Older adults with cognitive decline showed lower mean scores for safety practices. Further research with larger samples should explore the relationships between communication and safety practices and falls, their recurrence, and fear of new falls.

Effect of Ankle Weights as a Frailty Prevention Strategy in the Community-Dwelling Elderly: A Preliminary Report

Since the start of the COVID-19 pandemic, many healthy older adults have been less willing to engage in group exercise for fear of contracting this illness. Therefore, there is a need for an effective home-based exercise program to prevent frailty in the elderly. In this study, we assessed the effectiveness of ankle weights as a frailty prevention device for older adults. The study participants were aged 50−90 years and were screened for falls using the Motor Fitness Scale. Participants were divided into two age groups (≤70 and >70 years) for analysis. Older community-dwelling adults were invited to use ankle weights for 3 months. Seventy-four people responded to the invitation. Physical and cognitive status and performance (body composition, grip strength, standing on one leg with eyes open, the 30 s chair stand test (CS-30), Timed Up and Go test, walking speed, body sway, Japanese version of the Montreal Cognitive Assessment) were assessed before and after 3 months of intervention. CS-30 performance improved during the study. CS-30 reflects lower limb/trunk muscle strength and can be used to indicate the risk of falls. Wearing ankle weights can be recommended for strengthening the muscles of the lower limb and trunk in the elderly.

Balance Exercise Circuit for fall prevention in older adults: a randomized controlled crossover trial

Objectives

This study aimed to assess the immediate and short-term effects of the Balance Exercise Circuit (BEC) on muscle strength, postural balance, and quality of life, with the aim of preventing falls in older adults.

Methods

Twenty-two volunteers participated in this randomized controlled crossover study. Group A performed BEC training in the initial 3 months and received no intervention in the following 3 months. Group B received no intervention during the first 3 months and then participated in BEC training for the next 3 months. In addition, participants were followed for an additional 3 months. Muscle strength, postural balance, functional mobility, and quality of life were assessed, respectively, using an isokinetic dynamometer, force platform, TUG test, and the WHOQOL.

Results

After 3 months of training, Group A presented improved balance and rate of force development (RFD), while Group B presented improvements in RFD, TUG performance, and WHOQOL physical and psychological domains. Regarding the short-term effects, the participants maintained the training effects in WHOQOL balance, RFD, and the social domain. In addition, the number of falls decreased during follow-up.

Conclusion

The BEC intervention improved muscle strength, postural balance, and quality of life in older adults, in addition to reducing the risk of falls.

The Effectiveness of Proprioceptive Training for Improving Motor Performance and Motor Dysfunction: A Systematic Review

Objective

Proprioceptive training is any intervention aiming to improve proprioceptive function with the ultimate goal to enhance motor function and performance. It has been promoted as an approach to enhance athletic performance and as a tool for sensorimotor rehabilitation. Numerous studies sought to provide evidence on the effectiveness of the approach. However, many different training regimes claiming to train proprioception report a variety of sensorimotor measures that are not directly comparable. This, in turn, makes it difficult to assess effectiveness across approaches. It is the objective of this study to systematically review recent empirical evidence to gain an understanding of which outcome measures are most sensitive, which populations may benefit most from proprioceptive training, and what are the effects on proprioceptive and motor systems.

Methods

Four major databases were searched. The following inclusion criteria were applied: (1) A quantified pre- and post-treatment measure of proprioceptive function. (2) An intervention or training program believed to influence or enhance proprioceptive function. (3) Contained at least one form of treatment or outcome measure that is indicative of somatosensory function and not confounded by information from other sensory modalities. 4) The study reported of at least one quantified measure of motor performance.

Results

Of the 3,297 articles identified by the database search, 70 studies met the inclusion criteria and were included for further review. Across studies, proprioceptive training led to comparable gains in both proprioceptive (+46%) and motor performance (+45%). The majority of studies (50/70) applied active movement interventions. Interventions applying somatosensory stimulation were most successful in clinical populations. Joint position sense error (JPSE) was the most commonly used proprioceptive measure and presents a reliable and feasible measure for clinical use.

Conclusion

Proprioceptive training can lead to significant improvements in proprioceptive and motor function across a range healthy and clinical populations. Regimens requiring active movement of the trainee tended to be most successful in improving sensorimotor performance. Conclusive evidence on how long training gains are retained is still lacking. There is no solid evidence about the underlying long-term neuroplastic changes associated proprioceptive training.

The Dose-Response Efficacy of Physical Training on Frailty Status and Physical Performance in Community-Dwelling Elderly: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Purpose: This systematic review and meta-analysis was conducted to explore the effect of physical training on frailty status and physical performance in the community dwelling elderly. Methods: We set keywords and used the Boolean operator to search the CEPS, CINAHL, Cochrane Library, PubMed, MEDLINE, and EMBASE databases from inception to 10 August 2021. The search was limited to randomized controlled trials (RCTs) conducted within a five-year period. The Cochrane Collaboration bias assessment tool was used to assess article quality, and RevMan 5.4.1. software (Cochrane Training site based in London, UK) was used to conduct the meta-analysis. Results: Physical training was found to improve frailty status, physical performance, lower limb strength and balance. The best dose-response for physical training was 60 min per time, 2–3 times per week, for 3 months. Conclusion: Designing an appropriate physical training program can decrease the frailty score and increase physical performance in frail elderly in the community.

Effectiveness of a multicomponent exercise program to reverse pre-frailty in community-dwelling Chinese older adults: a randomised controlled trial

BACKGROUND

the Xiangya Hospital circuit training (X-CircuiT), was developed to reverse pre-frailty in Chinese older adults and determine potential mechanisms through which pre-frailty is reversed.

METHODS

this randomised controlled trial was performed at Xiangya Hospital, Changsha, China from September 2020 to May 2021. Forty-eight pre-frail older adults were enrolled. Participants were randomly assigned (1:1) to X-CircuiT (46 min/session, three supervised sessions/week for 3 months at a community health centre) or control (1-time advice on physical activity without supervised exercise). The primary outcome was the proportion of participants with pre-frailty after 3-month intervention. The secondary outcomes included absolute risk reduction (ARR), number needed to treat (NNT), and the changes in senior fitness, body composition and clinical measures.

RESULTS

among 48 participants (mean age, 72 years; women [65%]), 22 participants in the X-CircuiT (92%) and 21 participants in the control (88%) completed the study. After 3 months, the proportion of pre-frailty was significantly lower in the X-CircuiT group than the control (14% versus 95%, P < 0.001). The ARR and NNT were 82% [95% CI, 65-99] and 1 [1-2], respectively. X-CircuiT was associated with significant improvements in senior fitness indicators and body composition. No significant difference in blood chemistry, carotid ultrasound and echocardiography parameters was found between groups. No significant interaction was detected between sex, BMI, baseline peak oxygen consumption and study groups.

CONCLUSION

this study demonstrates that X-CircuiT could significantly reverse pre-frailty in Chinese older adults. The underlying mechanisms may involve X-CircuiT-induced improvements in body composition and senior fitness.The trial is registered at Chictr.org.cn. Number: ChiCTR2100048125.

Effectiveness of a 12-Week Multi-Component Training Program with and without Transcranial Direct-Current Stimulation (tDCS) on Balance to Prevent Falls in Community-Dwelling Older Adults: A Study Protocol

Simple Summary

Falls in community-dwelling individuals aged over 65 produce serious outcomes such as disability, morbidity, and mortality, as well as high healthcare costs. This research aims to assess whether a multicomponent training programme (McTP) combined with a transcranial direct-current stimulation device (tDCS), Halo Sport, produces improvements in balance and other gait-related parameters. Therefore, this study intends to test the efficacy of adding a tCDS device to an McTP in order to prevent falls in older adults by testing the safety, efficacy, and effectiveness of its implementation in care resources for the elderly.

Abstract

Approximately one-third of elderly people aged over 65 who live in the community experience falls every year, with the proportion increasing with age. Moreover, of those who fall, about half will fall again in the following year. The falls’ consequences include disability, morbidity, and mortality. Although many external and internal factors lead to falls, balance issues play a major role. Multi-component training programs (McTP) usually combine balance, strength, cardiorespiratory fitness, and flexibility, with studies reporting multiple benefits on the health-related quality of life. Halo Sport is a transcranial direct-current stimulation (tDCS) device with promising results for gait performance. This study aims to test the effectiveness of the introduction of a tCDS device to an McTP to prevent falls in older adults. The sample will consist of 46 people aged 65 years or older, randomly assigned to experimental (n = 23) and control (n = 23) groups. The experimental group will perform the McTP while wearing tDCS, and the control group will perform McTP without the device, for three sessions per week over 12 weeks. The main measures will provide information about (1) safety, (2) applicability, (3) balance, (4) number of falls, (5) physical fitness, (6) risk of falling, (7) fear of falling, (8) health-related quality of life, and (9) cognitive function. Among the practical implications of this program, it is intended to provide data on its safety and effectiveness to be implemented in different resources as a tool for the prevention of falls.

Implementation of a rehabilitation model in a Program of All-Inclusive Care for the Elderly (PACE): Preliminary data

BACKGROUND

Nursing home eligible participants in the Program of All-inclusive Care for the Elderly (PACE) are at high risk for falls. Physical function is a modifiable predictor of falls and an important target for prevention. We engaged a PACE site to explore feasibility of implementing progressive intensive rehabilitation to improve physical function and preliminary patient-level improvements.

METHODS

The research involved a mixed-methods, pre-post implementation study with longitudinal patient follow-up at one Denver PACE site. Older adults at risk for institutionalization (N = 28) took part in Screening and high-intensity interventions to Improve Falls risk and Transform expectations in age and aging (SHIFT) rehabilitation program over six weeks. Outcomes included the short physical performance battery (SPPB); 4-meter gait speed at baseline, discharge, and 6 and 12 months postdischarge from SHIFT. A focus group with staff explored facilitators and barriers to program implementation in the PACE setting and with complex patients and perceived effectiveness.

RESULTS

The rehabilitation team demonstrated high treatment fidelity to SHIFT (>80%). No treatment-specific adverse events were reported. SPPB scores and gait speeds improved significantly over time (p < 0.005). The average SPPB score at evaluation was 4.6 ± 0.24 compared to 7.7 ± 0.38 points at discharge. The average gait speed at evaluation was 0.58 ± 0.03 meters/second (m/s) compared to 0.79 ± 0.04 m/s at discharge. Common barriers to program completion included changes in health status and environmental factors (e.g., transportation).

CONCLUSIONS

Rehabilitation therapists incorporated a high-intensity resistance training program into routine care of complex older adults in PACE and improved pre-post physical function to levels above independence thresholds (SPPB ≥6; gait speed ≥0.65 m/s). Our pilot implementation study informed refinement of eligibility criteria, number of visits, and strategies to address long-term adherence to enhance scalability and optimize impact.

Effects of multicomponent exercise on the muscle strength, muscle endurance and balance of frail older adults: A meta-analysis of randomised controlled trials

OBJECTIVES

This study aims to evaluate the effects of multicomponent exercise on the muscle strength, muscle endurance and balance of frail older adults living in the community and provide the latest evidence from published randomised controlled trials (RCTs).

BACKGROUND

The number of frail older adults is rapidly increasing. Previous studies have reported that multicomponent exercise is one of the best types of intervention for increasing muscle strength, muscle endurance and balance for frail older adults. However, due to the small sample size and lack of evidential support, a meta-analysis of RCTs remains necessary.

METHODS

RCTs reporting the effects of multicomponent exercise on the muscle strength, muscle endurance and balance of frail older adults, published in English, were retrieved from five electronic databases: PubMed, CINAHL, Web of Science, Embase and Cochrane Library available from their inception up to January 2021. RevMan5.3 software was adopted for statistical analysis. This study followed the PRSIMA checklist.

RESULTS

A total of 10 articles and 667 patients were included in this study. Meta-analysis showed that multicomponent exercise could improve the muscle strength [MD = 2.46, p = .007], muscle endurance [MD = 2.16, p = .03] and balance [MD = .39, p = .03] of frail older adults, and subgroup analysis showed the muscle endurance of frail older adults was significantly improved as the intervention lasted for >12 weeks.

CONCLUSIONS

RCTs provided in this study show the latest evidence that multicomponent exercise can improve the muscle strength, endurance and balance of frail older adults and that long-duration (>12weeks) multicomponent exercise is more effective for improving muscle endurance.

RELEVANCE TO CLINICAL PRACTICE

Multicomponent exercise contributes to improving the muscle strength, muscle endurance and balance of frail older adults, so it can be considered as a complement to the physical function management programme for frail older adults.

Clinical Practice Guidelines for Managing Frailty in Community-Dwelling Korean Elderly Adults in Primary Care Settings

Aging has become a global problem, and the interest in healthy aging is growing. Healthy aging involves a focus on the maintenance of the function and well-being of elderly adults, rather than a specific disease. Thus, the management of frailty, which is an accumulated decline in function, is important for healthy aging. The adaptation method was used to develop clinical practice guidelines on frailty management that are applicable in primary care settings. The guidelines were developed in three phases: preparation (organization of committees and establishment of the scope of development), literature screening and evaluation (selection of the clinical practice guidelines to be adapted and evaluation of the guidelines using the Korean Appraisal of Guidelines for Research and Evaluation II tool), and confirmation of recommendations (three rounds of Delphi consensus and internal and external reviews). A total of 16 recommendations (five recommendations for diagnosis and assessment, 11 recommendations for intervention of frailty) were made through the guideline development process. These clinical practice guidelines provide overall guidance on the identification, evaluation, intervention, and monitoring of frailty, making them applicable in primary care settings. As aging and “healthy aging” become more and more important, these guidelines are also expected to increase in clinical usefulness.

An Assessment of Balance through Posturography in Healthy about Women: An Observational Study

The incidence of falls in adults constitutes a public health problem, and the alteration in balance is the most important factor. It is necessary to evaluate this through objective tools in order to quantify alterations and prevent falls. This study aims to determine the existence of alteration of balance and the influence of age in a population of healthy women. Static posturography was performed on 49 healthy adult women with no history of falls in four different situations using the Romberg test with the NedSVE/IBV^® platform. The variables studied were the body sway area and the anteroposterior and mediolateral displacements. The situation of maximum instability occurred in RGC (p = 0.001), with a significant increase in anteroposterior oscillations regarding the ML (p < 0.001), with no correlation to age. Age alone does not influence the balance in the sample studied, other factors must come together to alter it. The joint cancellation of visual and somatosensory afferents could facilitate the appearance of falls, given that it is a situation of maximum instability. Proprioceptive training is interesting as a preventive strategy for falls.

The Comparisons of Physical Functional Performances between Older Adults with and without Regular Physical Activity in Two Different Living Settings

We compared the physical function performances of community-dwelling and day care center older adults with and without regular physical activity (PA). A total of 163 Taiwanese older adults living in rural communities participated. PA habits and physical functional performances were assessed. The participants were divided into community-dwelling (CD) and senior day care (DC) center groups that were further classified into regular physical activity (RPA) and non-physical activity (NPA) subgroups. Comparison took place between subgroups. In the CD group, only the grip strength, pinch strength, and box and blocks test scored significantly better for the participants with regular PA. Muscle strength, flexibility, and three items of functional ability of participants with regular PA were significantly better in the DC group. An active lifestyle contributes to a good old-age life. The effective amount of PA and the reduction of sedentary time should be advocated to prevent frailty and disability in older adults.
