Interventions to promote long-term participation in physical activity after stroke: a systematic review of the literature

Co-design of a walking activity intervention for stroke survivors

Introduction

Stroke survivors may not maintain gains made in gait performance after task-oriented circuit training. Behavior change interventions may enhance the long-term adoption of physical activity. This study uses a co-design methodology to develop an intervention and tools to facilitate physical and exercise therapists in supporting an active lifestyle in stroke survivors, which is defined as a lifestyle that integrates daily walking performance with day-to-day activity.

Objectives

(1) To describe the insights generated during the co-design process; and (2) To describe the tools that were developed during the co-design process.

Methods

A multidisciplinary team consisting of staff members of the Royal Dutch Society for Physical Therapy, exercise and physical therapists specializing in neurorehabilitation and conducting task-oriented circuit class training in primary care settings or day therapy centers within residential care facilities, stroke survivors and their carers, experts in measuring movement behavior in stroke survivors, a company specializing in manufacturing sensors and related software, behavior change specialists, and co-designers all collaborated in a three-stage (define, develop, and deliver) co-design process.

Results

In the design process, the team iteratively developed a prototype accelerometer system for measuring walking performance with a feedback function for stroke survivors and their therapists and a prototype toolbox for therapists to support the facilitation of behavior change in their stroke survivors.

Discussion

This study shows how co-design can be applied to develop interventions for stroke survivors. Both the prototype system for measuring walking performance and the toolbox incorporate behavior change techniques to support a more physically active lifestyle in stroke survivors. Further research will investigate the feasibility of the intervention.

Similarities and differences in factors associated with high and low sedentary behavior after stroke: a mixed methods study

PURPOSE

To identify similarities and differences in factors affecting activity engagement between adults with stroke who are more and less sedentary.

MATERIALS AND METHODS

Data were pooled from two studies of adults with stroke (N = 36). Sedentary time was measured activPAL micro3. Participants completed activPAL interviews, which were analyzed using framework analysis. Participants were stratified into more and less sedentary groups based on activPAL data. Between-group similarities and differences were identified.

RESULTS

Adults with stroke (mean [SD] age = 65.8 [13.6] years, stroke chronicity = 40.5 [SD = 38.3] months, 36.1% female) were more sedentary (785.5 [64.7] sedentary minutes/day) and less sedentary (583.6 [87.4] sedentary minutes/day). Those who were more sedentary: engaged in basic activities of daily living, avoided activities, received assistance from other people, and did not use strategies to overcome barriers. Those who were less sedentary: engaged in instrumental and community activities, embraced new strategies, did activities with other people, and used strategies to overcome environmental barriers.

CONCLUSIONS

Factors affecting activity engagement differed between people who are more and less sedentary. Interventions that aim to reduce post-stroke sedentary behavior should consider the: (1) types of activities, (2) role of other people, and (2) application of strategies to overcome activity and environment-related barriers.

Accuracy, concurrent validity, and test-retest reliability of pressure-based insoles for gait measurement in chronic stroke patients

Introduction

Wearables are potentially valuable tools for understanding mobility behavior in individuals with neurological disorders and how it changes depending on health status, such as after rehabilitation. However, the accurate detection of gait events, which are crucial for the evaluation of gait performance and quality, is challenging due to highly individual-specific patterns that also vary greatly in movement and speed, especially after stroke. Therefore, the purpose of this study was to assess the accuracy, concurrent validity, and test-retest reliability of a commercially available insole system in the detection of gait events and the calculation of stance duration in individuals with chronic stroke.

Methods

Pressure insole data were collected from 17 individuals with chronic stroke during two measurement blocks, each comprising three 10-min walking tests conducted in a clinical setting. The gait assessments were recorded with a video camera that served as a ground truth, and pressure insoles as an experimental system. We compared the number of gait events and stance durations between systems.

Results and discussion

Over all 3,820 gait events, 90.86% were correctly identified by the insole system. Recall values ranged from 0.994 to 1, with a precision of 1 for all measurements. The F1 score ranged from 0.997 to 1. Excellent absolute agreement (Intraclass correlation coefficient, ICC = 0.874) was observed for the calculation of the stance duration, with a slightly longer stance duration recorded by the insole system (difference of -0.01 s). Bland-Altmann analysis indicated limits of agreement of 0.33 s that were robust to changes in walking speed. This consistency makes the system well-suited for individuals post-stroke. The test-retest reliability between measurement timepoints T1 and T2 was excellent (ICC = 0.928). The mean difference in stance duration between T1 and T2 was 0.03 s. We conclude that the insole system is valid for use in a clinical setting to quantitatively assess continuous walking in individuals with stroke.

Use of the Capability, Opportunity and Motivation Behaviour model (COM-B) to Understand Interventions to Support Physical Activity Behaviour in People with Stroke: An Overview of Reviews

OBJECTIVE

Physical activity in people with stroke remains low despite considerable research. This overview aimed to provide high-level synthesis and aid clinical decision-making. The Capability, Opportunity, Motivation-Behaviour (COM-B) model was used to classify interventions to understand which components improve physical activity behaviour in people with stroke.

DATA SOURCES

CINAHL, Cochrane Database, MEDLINE, PEDro, PsychINFO, SPORTDiscus.

REVIEW METHODS

A systematic search was conducted (November 2023) to identify reviews of interventions to improve physical activity in people with stroke. Results were screened and assessed for eligibility. Participant characteristics, intervention classification using COM-B, and effect of intervention were extracted. Quality was assessed using AMSTAR2, and Corrected Cover Analysis for study overlap. Narrative synthesis was used to understand components of interventions to improve physical activity behaviour.

RESULTS

1801 references were screened and 29 full-text references assessed for eligibility. Twenty reviews were included. Quality ranged from critically low (n = 3) to high (n = 10). Study overlap calculated using corrected cover area indicated slight overlap (0.028) and minimal reporting bias.The majority of participants were mobile with mild stroke and community dwelling. Twenty-three interventions were classified using COM-B. Three of twelve interventions classified to one aspect of the COM-B were effective. Fourteen of sixteen effective interventions combined at least two COM-B elements, ten of these combined capability and motivation.

CONCLUSION

Interventions including at least two elements of the COM-B are most likely to improve physical activity in mobile stroke survivors. Further research is needed to understand physical activity behaviour in those with moderate to severe stroke.

Sequential multiple assignment randomised trial to develop an adaptive mobile health intervention to increase physical activity in people poststroke in the community setting in Ireland: TAPAS trial protocol

INTRODUCTION

Stroke is the second-leading cause of death and disability globally. Participation in physical activity (PA) is a cornerstone of secondary prevention in stroke care. Given the heterogeneous nature of stroke, PA interventions that are adaptive to individual performance are recommended. Mobile health (mHealth) has been identified as a potential approach to supporting PA poststroke. To this end, we aim to use a Sequential Multiple Assignment Randomised Trial (SMART) design to develop an adaptive, user-informed mHealth intervention to improve PA poststroke.

METHODS AND ANALYSIS

The components included in the 12-week intervention are based on empirical evidence and behavioural change theory and will include treatments to increase participation in Structured Exercise and Lifestyle or a combination of both. 117 participants will be randomly assigned to one of the two treatment components. At 6 weeks postinitial randomisation, participants will be classified as responders or non-responders based on participants' change in step count. Non-responders to the initial treatment will be randomly assigned to a different treatment allocation. The primary outcome will be PA (steps/day), feasibility and secondary clinical and cost outcomes will also be included. A SMART design will be used to evaluate the optimum adaptive PA intervention among community-dwelling, ambulatory people poststroke.

ETHICS AND DISSEMINATION

Ethical approval has been granted by the Health Service Executive Mid-Western Ethics Committee (REC Ref: 026/2022). The findings will be submitted for publication and presented at relevant national and international academic conferences TRIALS REGISTRATION NUMBER: NCT05606770.

Impact of Active Physiotherapy on Physical Activity Level in Stroke Survivors: A Systematic Review and Meta-Analysis

BACKGROUND

Stroke survivors are frequently physically inactive. However, evidence of the effectiveness of active physiotherapy on physical activity level in stroke survivors is scarce.

METHODS

We conducted a systematic review and meta-analysis of randomized controlled trials according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement, covering electronic searches from inception to March 16, 2022. Participants: Stroke survivors living in the community. Intervention: Any active physiotherapy, that is, involving exercises that require voluntary effort. Outcome measure: Objective and subjective physical activity level.

RESULTS

Of 5590 identified references, 25 randomized controlled trials were eligible, and 21 had available data. The random-effects meta-analysis resulted in a small, significant effect size in favor of active physiotherapy measured using objective or subjective tools (21 studies, 1834 participants, standardized mean difference, 0.22 [95% CI, 0.04-0.40]; heterogeneity I2=65%), and a medium significant effect when objective tools were used (9 studies, 424 participants, standardized mean differences, 0.48 [95% CI, 0.03-0.92]; I2=73%). Meta-regression showed that 35% of the variance in trial outcome was explained by the measurement tool (objective or subjective) and 23% by age. None of the variances were associated with a specific dosage in terms of frequency, time, exercise duration, or the severity of the disability.

CONCLUSIONS

Active physiotherapy seems to increase objective physical activity in community-dwelling stroke survivors. However, the evidence is of very low certainty.

Effects of Exercise-Based Interventions on Physical Activity Levels in Persons With Parkinson's Disease: A Systematic Review With Meta-analysis

BACKGROUND AND PURPOSE

Parkinson's disease (PD) is the most common neurodegenerative movement disorder. Symptom severity leads to devastating consequences such as falls, immobility, impaired quality of life, and reduced general activity. Adopting a sedentary lifestyle creates a vicious circle, as physical inactivity can negatively affect the clinical domains of PD. Despite the recognition of the disease-modifying potential of physical activity (PA), achieving adequate exercise levels can be challenging for individuals with PD. This study aimed to investigate the repercussions of exercise-based interventions to improve PA levels in persons with PD through a systematic review with meta-analysis.

METHODS

A search was conducted from database inception to February 2021 across 3 databases: PubMed, Web of Science, and Scopus. Randomized controlled trials were included if they involved persons with PD, outcome measures associated with PA levels, and an exercise-based intervention. Two reviewers performed independent data extraction and methodologic quality assessment of the studies using the Downs and Black quality checklist.

RESULTS

A total of 6 studies were included in the study (1251 persons with PD). Four intervention types were identified: balance, strength, aerobic, and multimodal exercise (combination of several types of exercise programs). The meta-analysis showed that exercise interventions have a positive effect on PA (standard mean difference = 0.50, 95% CI =-0.02, 1.00; P = .06). The risk of bias was generally low.

CONCLUSIONS

The findings support the use of exercise-based interventions (aerobic exercise, balance exercise, strength exercise, and/or multimodal exercise) to improve PA levels. However, the limited number of studies and the heterogeneity of the interventions do not allow us to draw a definitive conclusion.

Identifying Unique Subgroups of Individuals With Stroke Using Heart Rate and Steps to Characterize Physical Activity

Background Low physical activity (PA) is associated with poor health outcomes after stroke. Step counts are a common metric of PA; however, other physiologic signals (eg, heart rate) may help to identify subgroups of individuals poststroke at varying levels of risk of poor health outcomes. Here, we aimed to identify clinically relevant subgroups of individuals poststroke based on PA profiles that leverage multiple data sources, including step count and heart rate data, from wearable devices. Methods and Results Seventy individuals poststroke participated. Participants wore a Fitbit Inspire 2 for 1 year and completed clinical assessments. We defined a group-based steps-per-minute threshold and an individual heart rate threshold to categorize each minute of PA into 1 of 4 states: high steps/high heart rate, low steps/low heart rate, high steps/low heart rate, and low steps/high heart rate. We used the proportion of time spent in each state along with steps per day, sedentary time, mean steps among minutes with high steps and high heart rate, and resting heart rate in a k-means clustering algorithm to identify subgroups and compared Activity Measure for Post-Acute Care Mobility T Score, Stroke Impact Scale, and gait speed among subgroups. We identified 3 subgroups, Active (n=8), Sedentary (n=29), and Deconditioned (n=33), which differed significantly on all clustering variables except resting heart rate. We observed significant differences in Activity Measure for Post-Acute Care Mobility T scores between subgroups, with the Deconditioned subgroup exhibiting the lowest score. Conclusions Quantifying PA with heart rate and step count using readily available wearable devices can identify clinically meaningful subgroups of individuals poststroke.

Keeping Active with Texting after Stroke (KATS): development of a text message intervention to promote physical activity and exercise after stroke

BACKGROUND

Post-stroke physical activity reduces disability and risk of further stroke. When stroke rehabilitation ends, some people feel abandoned by services and struggle to undertake physical activities that support recovery and health. The aim of this study was to codesign a novel text message intervention to promote physical activity among people with stroke and provide support when formal rehabilitation ends. This manuscript describes the intervention development processes that will inform future pilot and feasibility studies.

METHODS

The planned intervention was a series of text messages to be sent in a predetermined sequence to people with stroke at the end of rehabilitation. The intervention, underpinned by behaviour change theory and using salient behaviour change techniques, would provide daily messages offering encouragement and support for the uptake and maintenance of physical activity following stroke. The intervention was codesigned by a Collaborative Working Group, comprised of people with stroke, rehabilitation therapists, representatives from stroke charities and academics. A four-step framework was used to design the intervention: formative research on physical activity post-stroke, creation of the behaviour change text message intervention, pre-testing and refinement. Formative research included a review of the scientific evidence and interviews with community-dwelling people with stroke. Data generated were used by the Collaborative Working Group to identify topics to be addressed in the intervention. These were mapped to constructs of the Health Action Process Approach, and salient behaviour change techniques to deliver the intervention were identified. The intervention was rendered into a series of text messages to be delivered over 12 weeks. The draft intervention was revised and refined through an iterative process including review by people with stroke, their spouses, rehabilitation therapists and experts in the field of stroke. The messages encourage regular physical activity but do not prescribe exercise or provide reminders to exercise at specific times. They use conversational language to encourage engagement, and some are personalised for participants. Quotes from people with stroke provide encouragement and support and model key behaviour change techniques such as goal setting and coping planning.

DISCUSSION

Co-design processes were critical in systematically developing this theory and evidence-based intervention. People with stroke and rehabilitation therapists provided insights into perceived barriers post-rehabilitation and identified strategies to overcome them. The structured multistep approach highlighted areas for improvement through successive rounds of review. The intervention will be tested for acceptability, feasibility and effectiveness in future studies. This co-design approach could be used for interventions for other heath behaviours and with different populations.

Multimodal individualised intervention to prevent functional decline after stroke: protocol of a randomised controlled trial on long-term follow-up after stroke (LAST-long)

INTRODUCTION

Multimodal interventions have emerged as new approaches to provide more targeted intervention to reduce functional decline after stroke. Still, the evidence is contradictory. The main objective of the Life After Stroke (LAST)-long trial is to investigate if monthly meetings with a stroke coordinator who offers a multimodal approach to long-term follow-up can prevent functional decline after stroke.

METHODS AND ANALYSIS

LAST-long is a pragmatic single-blinded, parallel-group randomised controlled trial recruiting participants living in six different municipalities, admitted to four hospitals in Norway. The patients are screened for inclusion and recruited into the trial 3 months after stroke. A total of 300 patients fulfilling the inclusion criteria will be randomised to an intervention group receiving monthly follow-up by a community-based stroke coordinator who identifies the participants' individual risk profile and sets up an action plan based on individual goals, or to a control group receiving standard care. All participants undergo blinded assessments at 6-month, 12-month and 18-month follow-up. Modified Rankin Scale at 18 months is primary outcome. Secondary outcomes are results of blood tests, blood pressure, adherence to secondary prophylaxis, measures of activities of daily living, cognitive function, physical function, physical activity, patient reported outcome measures, caregiver's burden, the use and costs of health services, safety measures and measures of adherence to the intervention. Mixed models will be used to evaluate differences between the intervention and control group for all endpoints across the four time points, with treatment group, time as categorical covariates and their interaction as fixed effects, and patient as random effect.

ETHICS AND DISSEMINATION

This trial was approved by the Regional Committee of Medical and Health Research Ethics, REC no. 2018/1809. The main results will be published in international peer-reviewed open access scientific journals and to policy-makers and end users in relevant channels.

Physical Activity Level, Barriers, and Facilitators for Exercise Engagement for Chronic Community-Dwelling Stroke Survivors in Low-Income Settings: A Cross-Sectional Study in Benin

After a stroke incident, physical inactivity is common. People with stroke may perceive several barriers to performing physical activity (PA). This study aimed to document the PA level and understand the barriers and facilitators to engaging in PA for community-dwelling stroke survivors in Benin, a lower middle-income country. A cross-sectional study was conducted in three hospitals in Benin. Levels of PA were recorded by means of the Benin version of the International Physical Activity Questionnaire long form (IPAQ-LF-Benin), which is validated for stroke survivors in Benin. The perceived exercise facilitators and barriers were assessed by the Stroke Exercise Preference Inventory-13 (SEPI-13). A descriptive analysis and associations were performed with a Confidence Interval of 95% and <0.05 level of significance. A total of 87 participants (52 men, mean age of 53 ± 10 years, mean time after a stroke of 11 (IQR: 15) months and an average of 264.5 ± 178.9 m as distance on the 6 min walking test (6MWT) were included. Overall, stroke survivors in Benin reached a total PA of 985.5 (IQR: 2520) metabolic equivalent (METs)-minutes per week and were least active at work, domestic, and leisure domains with 0 MET-minutes per week. The overview of PA level showed that 52.9% of participants performed low PA intensity. However, 41.4% performed moderate PA or walking per day for at least five days per week. Important perceived barriers were lack of information (45.3%), hard-to-start exercise (39.5%), and travelling to places to exercise (29.9%). The preference for exercise was with family or friends, outdoors, for relaxation or enjoyment (90.2%), and receiving feedback (78.3%). Several socio-demographic, clinical, and community factors were significantly associated with moderate or intense PA (p < 0.05) in stroke survivors in this study. Our findings show that the PA level among chronic stroke survivors in Benin is overall too low relative to their walking capacity. Cultural factors in terms of the overprotection of the patients by their entourage and/or the low health literacy of populations to understand the effect of PA on their health may play a role. There is a need for new approaches that consider the individual barriers and facilitators to exercise.

WeWalk: walking with a buddy after stroke-a pilot study evaluating feasibility and acceptability of a person-centred dyadic behaviour change intervention

BACKGROUND

Evidence for benefits of physical activity after stroke is unequivocal. However, many people with stroke are inactive, spending > 80% of waking hours sedentary even when they have physical capacity for activity, indicating barriers to physical activity participation that are not physical. WeWalk is a 12-week person-centred dyadic behaviour change intervention in which a person with stroke (PWS) and a walking buddy form a dyad to work together to support the PWS to increase their physical activity by walking outdoors. This pilot study examined the feasibility of recruiting dyads, explored their perceptions of acceptability and their experiences using WeWalk, to identify required refinements before progression to a clinical trial.

METHODS

Design: A single-arm observational pilot study with qualitative evaluation.

INTERVENTION

WeWalk involved facilitated face-to-face and telephone sessions with a researcher who was also a behaviour change practitioner, supported by intervention handbooks and diaries, in which dyads agreed walking goals and plans, monitored progress, and developed strategies for maintaining walking.

EVALUATION

Descriptive data on recruitment and retention were collected. Interview data were collected through semi-structured interviews and analysed using thematic analysis, guided by a theoretical framework of acceptability.

RESULTS

We recruited 21 dyads comprising community dwelling PWS and their walking buddies. Ten dyads fully completed WeWalk before government-imposed COVID-19 lockdown. Despite lockdown, 18 dyads completed exit interviews. We identified three themes: acceptability evolves with experience, mutuality, and person-centredness with personally relevant tailoring. As dyads recognised how WeWalk components supported walking, perceptions of acceptability grew. Effort receded as goals and enjoyment of walking together were realised. The dyadic structure provided accountability, and participants' confidence developed as they experienced physical and psychological benefits of walking. WeWalk worked best when dyads exhibited relational connectivity and mutuality in setting and achieving goals. Tailoring intervention components to individual circumstances and values supported dyads in participation and achieving meaningful goals.

CONCLUSION

Recruiting dyads was feasible and most engaged with WeWalk. Participants viewed the dyadic structure and intervention components as acceptable for promoting outdoor walking and valued the personally tailored nature of WeWalk. Developing buddy support skills and community delivery pathways are required refinements. ISCTRN number: 34488928.

Evidence of High-Intensity Exercise on Lower Limb Functional Outcomes and Safety in Acute and Subacute Stroke Population: A Systematic Review

This systematic review investigated the effects of high-intensity exercise (HIE) on lower limb (LL) function in acute and subacute stroke patients. A systematic electronic search was performed in PubMed, CINAHL and the Web of Science from inception to 30 June 2022. Outcomes examined included LL function and measures of activities of daily living such as the Barthel index, 6 min walk test (6MWT), gait speed and Berg balance scale (BBS), adverse events and safety outcomes. The methodological quality and the quality of evidence for each study was assessed using the PEDro scale and the Risk of Bias 2 tool (RoB 2). HIE was defined as achieving at least 60% of the heart rate reserve (HRR) or VO₂ peak, 70% of maximal heart rate (HR_max), or attaining a score of 14 or more on the rate of perceived exertion Borg scale (6-20 rating scale). This study included randomized controlled trials (RCTs) which compared an intervention group of HIE to a control group of lower intensity exercise, or no intervention. All participants were in the acute (0-3 months) and subacute (3-6 months) stages of stroke recovery. Studies were excluded if they were not RCTs, included participants from a different stage of stroke recovery, or if the intervention did not meet the pre-defined HIE criteria. Overall, seven studies were included that used either high-intensity treadmill walking, stepping, cycling or overground walking exercises compared to either a low-intensity exercise (n = 4) or passive control condition (n = 3). Three studies reported significant improvements in 6MWT and gait speed performance, while only one showed improved BBS scores. No major adverse events were reported, although minor incidents were reported in only one study. This systematic review showed that HIE improved LL functional task performance, namely the 6MWT and gait speed. Previously, there was limited research demonstrating the efficacy of HIE early after stroke. This systematic review provides evidence that HIE may improve LL function with no significant adverse events report for stroke patients in their acute and subacute rehabilitation stages. Hence, HIE should be considered for implementation in this population, taking into account the possible benefits in terms of functional outcomes, as compared to lower intensity interventions.

The longitudinal association between movement behavior patterns and the course of participation up to one year after stroke

PURPOSE

(1) To investigate the differences in the course of participation up to one year after stroke between distinct movement behavior patterns identified directly after discharge to the home setting, and (2) to investigate the longitudinal association between the development of movement behavior patterns over time and participation after stroke.

MATERIALS AND METHODS

200 individuals with a first-ever stroke were assessed directly after discharge to the home setting, at six months and at one year. The Participation domain of the Stroke Impact Scale 3.0 was used to measure participation. Movement behavior was objectified using accelerometry for 14 days. Participants were categorized into three distinct movement behavior patterns: sedentary exercisers, sedentary movers and sedentary prolongers. Generalized estimating equations (GEE) were performed.

RESULTS

People who were classified as sedentary prolongers directly after discharge was associated with a worse course of participation up to one year after stroke. The development of sedentary prolongers over time was also associated with worse participation compared to sedentary exercisers.

CONCLUSIONS

The course of participation after stroke differs across distinct movement behavior patterns after discharge to the home setting. Highly sedentary and inactive people with stroke are at risk for restrictions in participation over time.Implications for rehabilitationThe course of participation in people with a first-ever stroke up to one year after discharge to the home setting differed based on three distinct movement behavior patterns, i.e., sedentary exercisers, sedentary movers and sedentary prolongers.Early identification of highly sedentary and inactive people with stroke after discharge to the home setting is important, as sedentary prolongers are at risk for restrictions in participation over time.Supporting people with stroke to adapt and maintain a healthy movement behavior after discharge to the home setting could prevent potential long-term restrictions in participation.

Physical Activity After Transient Ischemic Attack or Mild Stroke Is Business as Usual

BACKGROUND AND PURPOSE

Regular, sustained moderate-to-vigorous physical activity (MVPA) is a recommended strategy to reduce the risk of recurrent stroke for people who have had transient ischemic attack (TIA) or mild stroke. This study aimed to explore attitudes toward, and experience of engaging in physical activity by adults following a TIA or mild stroke.

METHODS

Constructivist grounded theory methodology informed data collection and analysis. Interviews from 33 adults with TIA or mild stroke (mean age 65 [SD 10] years, 48% female, 40% TIA) were collected.

RESULTS

Business as usual characterized physical activity engagement post-TIA or mild stroke. Most participants returned to prestroke habits, as either regular exerciser or nonexerciser, with only a small number making changes. Influencing factors for physical activity participation included information, challenges, strategies, and support. Business as usual was associated with a perceived lack of information to suggest a need to change behaviors. Nonexercisers and those who decreased physical activity emphasized challenges to physical activity, while regular exercisers and those who increased physical activity focused on strategies and support that enabled participation despite challenges.

DISCUSSION AND CONCLUSION

Information about the necessity to engage in recommended physical activity levels requires tailoring to the needs of the people with TIA or mild stroke. Helpful information in combination with support and strategies may guide how to navigate factors preventing engagement and might influence the low level of physical activity prevalent in this population.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1 available at: http://links.lww.com/JNPT/A376).

We Walk: a person-centred, dyadic behaviour change intervention to promote physical activity through outdoor walking after stroke-an intervention development study

OBJECTIVES

To develop We Walk, a theoretically informed, 12-week person-centred dyadic behaviour change intervention to increase physical activity (PA) in community-dwelling people with stroke (PWS) through outdoor walking.

DESIGN

Three-phase intervention development study. Phase 1: we reviewed literature on barriers and facilitators to PA after stroke and mapped them to the Behaviour Change Wheel and Theoretical Domains Framework to define intervention components. The Health Action Process Approach determined intervention structure underpinned by person-centred principles. Phase 2: stakeholder focus groups involving PWS, their companions and health professionals reviewed the draft intervention, and experts in behaviour change were consulted. Phase 3: informed by phases 1 and 2, the intervention and form of delivery were refined, with final review through patient and public involvement.

SETTING

Three Scottish community rehabilitation stroke services.

PARTICIPANTS

Twenty-three ambulatory community-dwelling PWS and their companions, thirty-seven health and exercise professionals, seven behaviour change experts.

RESULTS

Phase 1 determined key intervention components: information about benefits of walking; developing motivation and confidence to walk; facilitating dyadic goal setting and making plans together; monitoring walking, overcoming challenges; and maintaining walking behaviour. Phase 2 review by stakeholder focus groups and behaviour change experts endorsed intervention components and structure, emphasising dyadic relational aspects as central to potential success. In phase 3, intervention content and handbooks for PWS and buddies were finalised. Healthcare professionals proposed third-sector delivery as most appropriate for intervention delivery. A detailed delivery manual was developed. Participants preferred facilitated face-to-face and telephone delivery.

CONCLUSIONS

Our multilens intervention development approach ensured this novel intervention was evidence-informed, person-centred, theoretically coherent provided appropriate social support, and addressed issues of concern to PWS. This study established intervention components and structure and identified operational issues critical to future success. Future research will pilot and refine We Walk and evaluate acceptability, feasibility, effectiveness and cost-effectiveness.

Capability, opportunity, motivation, and social participation after stroke

BACKGROUND

Stroke survivors report limited social participation, despite it being an important rehabilitation outcome. Interdisciplinary interventions for increasing social participation amongst stroke survivors lack theoretical guidance and evidence-based approaches. The Behavior Change Wheel (BCW) theorizes that capability, opportunity, and motivation contribute to behavior change.

OBJECTIVES

This study applied the BCW to understand the relationship between social participation and stroke survivors' capability, opportunity, and motivation.

METHODS

In this cross-sectional study, we recruited 30 community-dwelling adult stroke survivors. Assessments explored the frequency and satisfaction of social participation; physical and psychological capability; environmental accessibility and social opportunity; and motivation. A linear regression analysis was done.

RESULTS

Motivation (R² change = 29.3%, ß = 0.55) and environmental opportunity (R² change = 11%, ß = 0.39) were statistically significant predictors of social participation frequency. Motivation (R² change = 36.9%, ß = 0.61) was the only statistically significant predictor of satisfaction with social performance.

CONCLUSIONS

Motivation and environmental accessibility are statistically significant independent predictors of frequency of social participation after stroke. Motivation is the strongest predictor of satisfaction with social participation. Clinicians may support stroke survivors to promote social participation using approaches that increase motivation and environmental accessibility. Development of such theoretically sound interventions may be guided by the BCW.

Leveraging Factors of Self-Efficacy and Motivation to Optimize Stroke Recovery

The International Classification of Functioning, Disability and Health framework recognizes that an individual's functioning post-stroke reflects an interaction between their health condition and contextual factors encompassing personal and environmental factors. Personal factors significantly impact rehabilitation outcomes as they determine how an individual evaluates their situation and copes with their condition in daily life. A key personal factor is self-efficacy-an individual's belief in their capacity to achieve certain outcomes. Self-efficacy influences an individual's motivational state to execute behaviors necessary for achieving desired rehabilitation outcomes. Stroke rehabilitation practice and research now acknowledge self-efficacy and motivation as critical elements in post-stroke recovery, and increasing evidence highlights their contributions to motor (re)learning. Given the informative value of neuroimaging-based biomarkers in stroke, elucidating the neurological underpinnings of self-efficacy and motivation may optimize post-stroke recovery. In this review, we examine the role of self-efficacy and motivation in stroke rehabilitation and recovery, identify potential neural substrates underlying these factors from current neuroimaging literature, and discuss how leveraging these factors and their associated neural substrates has the potential to advance the field of stroke rehabilitation.

IMproving Physical ACtivity after stroke via Treadmill training (IMPACT) and self-management: a randomised trial

Aim: To determine if treadmill training embedded in self-management education commencing during stroke inpatient rehabilitation results in more physical activity than usual gait training.

Method: A prospective, parallel-group, randomised trial with concealed allocation, blinded measurement and intention-to-treat analysis involving 119 stroke survivors undergoing rehabilitation who were able to walk independently was undertaken. The experimental group undertook treadmill training (40-60% heart rate reserve) and self-management education for 30 minutes, three times a week for 8 weeks and the control group undertook the same amount of usual gait training. Outcomes were measured at baseline (Week 0), on completion of the intervention (Week 8) and beyond the intervention (Week 26). The primary outcome was physical activity measured as steps/day using an activity monitor. Secondary outcomes were walking ability, cardiorespiratory fitness, cardiovascular risk, depression, self-efficacy, perception of physical activity, participation, and quality of life.

Results: After 8 weeks, the experimental group took 1436 more steps/day (95% CI 229 to 2643) than the control group. By 6 months, they took 871 more steps/day (95% CI -385 to 2129) than the control group. There was no difference between groups in any other outcome.

Conclusions: In individuals undergoing rehabilitation after stroke, 8 weeks of treadmill training embedded in self-management resulted in more physical activity than usual gait training and this was largely maintained at 6 months, despite little effect on walking or cardiorespiratory fitness, suggesting the self-management was responsible.

Evaluating the impact of a training program to support transitioning from the hospital to the community for people after stroke: a community case study

Background

The transitions in care along the stroke recovery path are challenging, particularly in finding mechanisms to continue one’s recovery once at home. We aim to evaluate the impact of training physiotherapists and fitness instructors from one regional community together to deliver an evidence-based group exercise program starting in the hospital and transitioning to the community using an implementation approach.

Methods

The evidenced based exercise program Fitness and Mobility Exercise (FAME) for stroke was chosen as the intervention. Data from interviews with stakeholders (community centre and health authority hospital staff including a physiotherapy navigator) was transcribed and themes evaluated using the RE-AIM (Reach, Efficacy, Adoption, Implementation, Maintenance) framework. These data were supplemented by information collected as a quality assurance project within the health authority.

Results

Two programs were established; one in the community centre (run over 15 months by fitness instructors) and one in the regional hospital (run over 12 months by a rehabilitation assistant under the direction from a physiotherapist). Transitions in care were facilitated by implementing the same evidence-based group exercise class in both the hospital and community setting, so people living with stroke could seamlessly move from one to another. An existing physiotherapist navigator service also was valued as a support for the transitions between the two centres for people with stroke. The hospital group accessed group-based physiotherapy service on average 31 days earlier than they were able to in a one-to-one format.

Conclusions

This case study described the implementation of the Fitness and Mobility Exercise (FAME) program in one community and the use of a physiotherapist navigator to assist transition between them. After a community training workshop, FAME programs were established within the health authority and the community centre. FAME program participants within the health authority benefited from reduced wait times to access hospital outpatient physiotherapy service. Improvements in function were measured in and reported by the people after stroke attending either the health authority or community centre FAME groups.

Active Participation of Care Partners in a Physical Activity Intervention Alongside People with Stroke: A Feasibility Study

Purpose: This study investigated the feasibility of a physical activity intervention for people with stroke and their care partners and the role social support plays in physical activity adherence. Method: The study used a single-group, pretest-posttest design with follow-up. Participants were adults with chronic stroke and their care partners. The intervention consisted of 8 weeks of structured, group-based physical activity classes, followed by 19 weeks of self-directed physical activity. Recruitment, adherence, safety, and retention were assessed. Familial social support was assessed before and after the 8-week structured portion and again 19 weeks later. Results: A total of 21 participants (15 people with stroke, 6 care partners), mean age 67.6 (SD 11.6) years, were recruited; 19 (90.5%) completed the 19-week assessment. No adverse events were experienced during the programme. Attendance during the 8-week portion was better than during the 19-week portion (mean difference 0.95; p < 0.001; 95% CI: 0.71, 1.19 visits/wk). No relationship was found between social support and physical activity adherence (p > 0.05). Conclusions: Involvement of care partners in a physical activity intervention is feasible and safe. Both people with stroke and their care partners may require ongoing support to participate in long-term physical activity. The relationship between social support and physical activity adherence requires further study.

Association Between Physical Activity and Mortality Among Community-Dwelling Stroke Survivors

BACKGROUND AND OBJECTIVE

To determine the relationship between physical activity (PA) and mortality in community-dwelling stroke survivors.

METHODS

The Canadian Community Health Survey was used to obtain self-reported PA across 4 survey years and was linked to administrative databases to obtain prior diagnosis of stroke and subsequent all-cause mortality. PA was measured as metabolic equivalents (METs) per week and meeting minimal PA guidelines was defined as 10 MET-h/wk. Cox proportional hazard regression models and restricted cubic splines were used to determine the relationship between PA and all-cause mortality in respondents with prior stroke and controls, adjusting for sociodemographic factors, comorbidities, and functional health status.

RESULTS

The cohort included 895 respondents with prior stroke and 97,805 controls. Adhering to PA guidelines was associated with lower hazard of death for those with prior stroke (adjusted hazard ratio [aHR] 0.46, 95% confidence interval [CI] 0.29-0.73) and controls (aHR 0.69, 95% CI 0.62-0.76). There was a strong dose-response relationship in both groups, with a steep early slope and the vast majority of associated risk reduction occurring between 0 and 20 MET-h/wk. In the group of stroke respondents, PA was associated with greater risk reduction in those <75 years of age (aHR 0.21, 95% CI 0.10-0.43) compared to those ≥75 years of age (aHR 0.68, 95% CI 0.42-1.12).

DISCUSSION

PA was associated with lower all-cause mortality in an apparent dose-dependent manner among those with prior stroke, particularly in younger stroke survivors. Our findings support efforts towards reducing barriers to PA and implementation of PA programs for stroke survivors in the community.

CLASSIFICATION OF EVIDENCE

This study provides Class III evidence that in community-dwelling survivors of stroke, adhering to physical activity guidelines was associated with lower hazard of death.

Comparing the physical activity of stroke survivors in high-income countries and low to middle-income countries

BACKGROUND

Low physical activity levels in people with stroke may contribute to higher risk of cardiovascular disease morbidity and mortality. Differences in economic status, culture and the built environment may influence the applicability of interventions developed in high income countries (HIC) for stroke survivors in low to middle-income countries (LMIC).

PURPOSE

To compare physical activity levels of stroke survivors in HIC and LMIC and to explore the influence of lower limb impairment on physical activity levels.

METHODS AND MATERIALS

An exploratory secondary analysis of observational data on physical activity levels of stroke survivors from Australia (HIC) and India (LMIC). Physical activity variables (step count, light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA)) were measured by accelerometery. Comparisons of physical activity levels between (a) Australian and Indian stroke survivors and (b) participants with and without lower limb impairments were performed using independent t-tests or Mann-Whitney U tests.

RESULTS

There were no significant differences in physical activity levels between (i) Australian and Indian stroke survivors (step count mean difference 201 steps [-1375 to 974], LPA mean difference -24 min [-22 to 69], MVPA mean difference 2 min [-8 to 3]), and (ii) stroke survivors with and without lower limb impairments in either country.

CONCLUSION

Stroke survivors were highly inactive in both countries. Despite differences in economic status, cultural influences and the built environment, the physical activity of stroke survivors in Australia and India did not differ. People with and without lower limb impairment also had similar physical activity levels.

The course of physical functioning in the first two years after stroke depends on peoples' individual movement behavior patterns

BACKGROUND AND PURPOSE

Deterioration of physical functioning after stroke in the long term is regarded as a major problem. Currently, the relationship between "peoples'" movement behavior patterns (the composition of sedentary behavior and physical activity during waking hours) directly after stroke and the development of physical functioning over time is unknown. Therefore, the objectives of this study were to investigate (1) the course of physical functioning within the first two years after returning home after stroke, and (2) the association between physical functioning and baseline movement behavior patterns.

METHOD

In the longitudinal RISE cohort study, 200 persons with a first-ever stroke discharged to the home-setting were included. Participants' physical functioning was assessed within three weeks, at six months, and one and two years after discharge using the Stroke Impact Scale (SIS) 3.0 subscale physical and the five-meter walk test (5MWT). Three distinct movement behavior patterns were identified in a previous study at baseline and were used in the current study: (1) sedentary exercisers (sufficiently active and 64% of waking hours sedentary), (2) sedentary movers' (inactive and 63% of waking hours sedentary), and (3) sedentary prolongers (inactive and >78% of waking hours sedentary accumulated in long prolonged bouts). The association between movement behavior patterns and the course of physical functioning was determined using longitudinal generalized estimating equations analyses.

RESULTS

Overall participants' physical functioning increased between discharge and six months and declined from six months up to two years. Physical functioning remained stable during the first two years after stroke in sedentary exercisers. Physical functioning improved during the first six months after discharge in sedentary movers and sedentary prolongers and deteriorated in the following six months. Only physical functioning (SIS) of sedentary prolongers further declined from one up to two years. A similar pattern was observed in the 5MWT.

CONCLUSION

Movement behavior patterns identified directly after returning home in people with stroke are associated with and are predictive of the course of physical functioning. Highly sedentary and inactive people with stroke have unfavorable outcomes over time than individuals with higher amounts of physical activity.

Feasibility of integrating survivors of stroke into cardiac rehabilitation: A mixed methods pilot study

Background

Survivors of stroke are often deconditioned and have limited opportunities for exercise post-rehabilitation. Cardiac Rehabilitation (CR), a structured exercise program offered post-cardiac event in the United States (U.S.), may provide an opportunity for continued exercise.

The purpose of this study was to examine the feasibility of integrating survivors of stroke into an existing, hospital-based CR program through an assessment of (1) recruitment, uptake and retention, (2) adherence and fidelity, (3) acceptability and (4) safety.

Methods

A mixed methods design combined a single group, pre-post design, pilot feasibility study with an imbedded qualitative inquiry. Survivors of stroke were recruited into a standard 12-week, 36 visit CR program.

Results

Fifty-three survivors were referred, 29 started and 24 completed the program. Program uptake rate was 55% and completion rate was 83%. Eleven completers and one non-completer participated in the qualitative interviews. Program completers attended an average of 25.25 (SD 5.82) sessions with an average of 38.93 (SD 5.64) exercise minutes per session while reaching targeted rate of perceived exertion levels. Qualitative themes included perceived benefits of an individualized program in a group setting, positive interactions with qualified staff, opportunities for socialization, and regular monitoring and staff attentiveness promoting feelings of safety.

Conclusions

Survivors of stroke were able to meet Medicare standard dosage (frequency and session duration) and rate of perceived intensity goals, and perceived the program as needed regardless of their mobility limitations or previous exercise experience. Primary challenges included managing referrals and uptake. Results support feasibility and benefit for survivors to integrate into U.S. CR programs.

Factors related to daily use of the paretic upper limb in patients with chronic hemiparetic stroke-A retrospective cross-sectional study

AIMS

The present study aimed to determine factors associated with the frequency of paralyzed upper extremity (UE) use in chronic stroke patients with severe UE functional deficiency.

METHODS

We retrospectively reviewed the medical records of 138 consecutive patients, and 117 was analyzed (median age, 55 [range, 18-85] years; median stroke duration, 24.5 [range, 7-302] months) with chronic hemiparetic stroke who were admitted to our hospital for intensive upper extremity rehabilitation. The mean Fugl-Meyer Assessment (FMA) UE score was 28.6. All of them are independent in their activity of daily living (ADL) and without remarkable cognitive deficits. Amount-of-use score of Motor Activity Log-14 (MAL-AOU) was applied as the index of daily use of affected UE. The following parameters were examined as the explanatory variables: demographics, proximal and distal sub-scores of FMA UE, Modified Ashworth Scale (MAS), and sensory function scores in the Stroke Impairment Assessment Set (SIAS).

RESULTS

The median MAL-AOU score was 0.57 [range, 0.28-0.80]. Ordinal regression analysis revealed that FMA proximal, FMA distal, and SIAS sensory function (touch) were associated with AOU score of MAL-14 (Pseudo R-square = 0.460).

CONCLUSION

Not only motor but also sensory function, especially tactile sensation, play a crucial role in the daily use of affected UE in chronic stroke patients with severe UE hemiparesis.

Personal and social factors that influence physical activity levels in community-dwelling stroke survivors: A systematic review of qualitative literature

OBJECTIVES

To determine the personal and social factors perceived to influence physical activity levels in stroke survivors.

DATA SOURCES

Four electronic databases (MEDLINE, CINAHL, PubMed and Embase) were searched from inception to November 2020, including reference and citation list searches.

STUDY SELECTION

The initial search yielded 1499 papers, with 14 included in the review. Included articles were peer-reviewed, qualitative studies, reporting on the perceived factors influencing physical activity levels of independently mobile community-dwelling adults, greater than 3 months post stroke.

DATA EXTRACTION

Data extracted included location, study aim, design, participant and recruitment information and how data were collected and analysed.

DATA SYNTHESIS

Thematic analysis was undertaken to identify meanings and patterns, generate codes and develop themes. Five main themes were identified: (i) Social networks are important influencers of physical activity; (ii) Participation in meaningful activities rather than 'exercise' is important; (iii) Self-efficacy promotes physical activity and physical activity enhances self-efficacy; (iv) Pre-stroke identity related to physical activity influences post-stroke physical activity; and (v) Formal programmes are important for those with low self-efficacy or a sedentary pre-stroke identity.

CONCLUSIONS

Physical activity levels in stroke survivors are influenced by social activities and support, pre-stroke identity, self-efficacy levels and completion of activities that are meaningful to stroke survivors.

Integrating Survivors of Stroke Into Exercise-Based Cardiac Rehabilitation Improves Endurance and Functional Strength

Background

Cardiac rehabilitation (CR) is a structured exercise program prevalent in the United States for people with cardiovascular disease that has been shown to increase cardiovascular endurance and improve quality of life. Despite similar cardiovascular risk factors, stroke is not among the covered diagnoses for CR. The purpose of this study was to examine the participant impact of integrating survivors of stroke into the exercise portion of an existing hospital‐based CR program through measures of physical function and other health impacts and through qualitative evaluation of participant perception.

Methods and Results

Subacute and chronic survivors of stroke were integrated into a standard 12‐week, 3 sessions per week, exercise‐based CR program. A total of 29 began the program, 24 completed the program, and 18 were available for 6‐month follow‐up. Quantitative measures were compared preprogram with postprogram with t‐test or equivalent, and preprogram with postprogram to 6‐month follow‐up with ANOVA or equivalent. Semistructured interviews were completed with 11 participants postprogram. Exercise‐based CR had significant impacts on cardiovascular endurance preprogram to postprogram, with maintenance at 6‐month follow‐up. The participants improved on the 6‐minute walk test on average by 61.92 m(95% CI, 33.99–89.84 m), and maximum metabolic equivalents improved by a median of 3.6 (interquartile range, 2.35). Five times sit to stand (functional strength) improved preprogram to postprogram by a median of 2.85 s (interquartile range, 4.03 s). Qualitative findings highlight additional health improvements. Most participants (83% [15/18]) reported continued exercise at follow‐up.

Conclusions

Exercise‐based CR has the potential to improve cardiovascular endurance, health status, and quality of life for survivors of stroke.

Intensity of daily physical activity - a key component for improving physical capacity after minor stroke?

PURPOSE

Elucidating the complex interactions between physical activity (PA), a multidimensional concept, and physical capacity (PC) may reveal ways to improve rehabilitation interventions. This cross-sectional study aimed to explore which PA dimensions are related to PC in people after minor stroke.

MATERIALS AND METHODS

Community dwelling individuals >6 months after minor stroke were evaluated with a 10-Meter-Walking-Test (10MWT), Timed-Up & Go, and the Mini Balance Evaluation System Test. The following PA outcomes were measured with an Activ8 accelerometer: counts per minute during walking (CPM_walking; a measure of intensity), number of active bouts (frequency), mean length of active bouts (distribution), and percentage of waking hours in upright positions (duration). Multivariable linear regression models, adjusted for age, sex and BMI, were used to assess the relationships between PC and PA outcomes.

RESULTS

Sixty-nine participants [62.2 ± 9.8 years, 61% male, 20 months post onset (IQR 13.0-53.5)] were included in the analysis. CPM_walking was significantly associated to PC in the 10MWT (std. ß = 0.409, p = 0.002), whereas other associations between PA and PC were not significant.

CONCLUSIONS

The PA dimension intensity of walking is significantly associated with PC, and appears to be an important tool for future interventions in rehabilitation after minor stroke.Implications for rehabilitationIt is recommended to express physical activity after minor stroke in multiple dimensions such as intensity, frequency, duration and distribution.In particular, intensity of physical activity measured with accelerometer counts is most closely related to physical capacity.The findings of this study underline the importance of being physically active beyond a certain intensity.In future development of interventions and guidelines that aim to promote daily physical activity, intensity should be taken into account.

Effect of individualized coaching at home on walking capacity in subacute stroke patients: A randomized controlled trial (Ticaa'dom)

BACKGROUND

The gains in walking capacity achieved during rehabilitation often plateau, or are lost, when the patient returns home. Moreover, maintaining or increasing the patient's daily physical activity level after a stroke remains challenging. We aimed to evaluate the effectiveness of a six-month individualized coaching program at home on walking capacity, as evaluated by the six-minute walk test in subacute stroke patients.

METHODS

Stroke patients in the physical medicine and rehabilitation service participated in a monocentric observer blinded randomized controlled trial with two groups, intervention versus usual care control. The inclusion criteria were: age≥18 years, first ischemic or hemorrhagic stroke, and stroke within<6 months. Participants were randomly assigned (blocks of variable size) to an intervention group (EG) receiving individualized coaching on physical activity, or to a control group (CG) receiving standard care. The six-month program was composed of monitored physical activity, home visits and a weekly phone call. Participants were evaluated after hospital discharge (T0), at the end of the six-month program (T1) and six months later(follow-up; T2). The primary outcome was the walking distance performance, as evaluated with the six-minute walk test at T1.

RESULTS

Eighty-three participants (age: 61y [IQR=22]; time post-stroke: 2.4 month [IQR=1.7]; Barthel index: 100[IQR=5]) were included in the study: (EG, n=41; CG, n=42). The difference between the two groups was not significant at T1(418m [IQR=165] for the EG and 389m [IQR=188] for the CG; P=0.168) and at T2(425m [IQR=121] for the EG vs. 382m [IQR=219] for the CG; P=0.208).

CONCLUSION

Our study shows no difference in the six-minute walk test between the two groups of subacute stroke patients after 6 months of the individualized coaching program, combining home visits, feedback on daily performance and weekly telephone calls. http://ClinicalTrials.gov (NCT01822938).

Effects of detraining on cardiorespiratory fitness of individuals with chronic stroke

BACKGROUND

Aerobic training can improve cardiorespiratory fitness in individuals after stroke. However, the effects of short-term and long-term detraining are not well known.

OBJECTIVE

To determine the effects of short-term (1-month) and long-term (6-month) detraining on cardiorespiratory fitness (VO_2peak) of individuals after stroke, who participated in aerobic training.

METHODS

A cohort study was developed. Twenty adults (57 ± 11 years old) with stroke were included. After completing an outpatient aerobic training, participants were divided into gain group (VO_2peak increase >1.3 ml.kg^-1.min^-1 from before to immediately after the training) or non-gain group (VO_2peak change ≤1.3 ml.kg^-1.min^-1). Cardiorespiratory fitness (VO_2peak), obtained by the cardiopulmonary exercise test was assessed one and 6 months after the end of the training (short- and long-term detraining, respectively), or collected retrospectively from patient chart (before and after the training).

RESULTS

There was found a significant interaction effect (time*group) for VO_2peak (F= 6.108;p < 0,001). Higher values in the VO_2peak observed in the gain group with the aerobic training (F = 25.86; p< .001) were significantly reduced with short-term detraining, reaching values similar to that observed before the training and to that of the non-gain group (F = 14.81;p= .001). Both groups had similar VO_2peak values within long-term detraining (F = 2.70;p= .12), with no significant differences from the values observed before the training and after short-term detraining (0.11 ≤ p≤ 1.00).

CONCLUSIONS

Detraining on cardiorespiratory fitness of individuals after chronic stroke occurred within only 1 month. Therefore, it is important to maintain aerobic training throughout life.

The Role of Physical Therapy in Multiple Risk Factor Management Poststroke: A Scoping Review

BACKGROUND AND PURPOSE

Individuals after stroke often have multiple chronic conditions, such as hypertension, diabetes, dyslipidemia, obesity, and tobacco use. These comorbidities not only are commonly found in individuals with stroke, but also negatively affect functional outcomes and increase risk for hospital readmission and overall mortality. It is important for physical therapists to address the whole person during treatment after stroke, including comorbidities, not just the problems resulting from the stroke itself. However, it is unclear how common it is for physical therapists to address multiple diagnoses at once using a wellness model. Therefore, the purpose of this scoping review was to examine current evidence regarding the role of physical therapy in addressing modifiable risk factors for individuals after stroke, to identify gaps in research associated with physical therapy management of related comorbid diagnoses during treatment for stroke.

METHODS

A scoping review methodology was utilized searching PubMed and CINAHL databases to identify interventional research studies specifically addressing multiple modifiable risk factors utilizing physical therapy for individuals after stroke.

RESULTS

The initial search yielded 5358 articles and 12 articles met full inclusion criteria. Only 2 studies included participants with significant mobility impairments, and none included individuals with communication impairments. Only 4 of the 12 studies provided education in their design. Eight studies did not include any patient-reported outcome measures. Only 3 studies included long-term follow-up assessments.

DISCUSSION

Secondary stroke risk factors can be positively addressed using physical therapy interventions; however, more research is needed regarding individuals with moderate to severe mobility or communication deficits. Opportunities for physical therapy research to address stroke risk factors in this complex population include expanding follow-up periods, improving educational interventions, and including caregivers in study design.

CONCLUSIONS

This review highlights the need for better integration of clinical considerations into stroke rehabilitation research as a whole, along with the need for additional research regarding the role physical therapy can play in addressing multimorbidity in individuals with stroke.

A feasibility, acceptability and fidelity study of a multifaceted behaviour change intervention targeting free-living physical activity and sedentary behaviour in community dwelling adult stroke survivors

Background

Despite the benefits of physical activity for walking ability, balance, and mood, less than 30% of stroke survivors engage in recommended levels of physical activity with high levels of sedentary behaviour observed. This study aims to assess the feasibility, acceptability and fidelity of a theory- and evidence-based multifaceted behaviour change intervention targeting free-living physical activity and sedentary behaviour after stroke.

Methods

This study will be set in community stroke services in the North East of England and will assess the feasibility of a behaviour change intervention targeting free-living physical activity and sedentary behaviour of stroke survivors and consultation behaviour of the healthcare professionals to support stroke survivors to make these lifestyle changes. Up to 35 stroke survivors currently receiving stroke rehabilitation within the study catchment area with capacity and no contraindications to increasing physical activity/reducing sedentary behaviour will be recruited. Stroke survivors will receive a supported self-management physical activity/sedentary behaviour programme incorporating provision of information, goal setting, action planning, barrier identification, coping planning, self-monitoring and feedback on physical activity and sedentary behaviour. The programme will be supported by up to 12 healthcare professionals (HCPs) recruited from the community stroke services taking part in the study. The HCPs will deliver at least two face-to-face sessions (baseline, review and subsequent reviews if necessary) and provide a range of personalised tools to support each individual stroke survivor (e.g. workbook, self-monitoring tools, information on local resources). The consultation behaviour of the HCPs will be targeted via a training programme incorporating face-to-face training, a training manual and individual feedback on intervention programme delivery from the study research team. The feasibility, acceptability and fidelity of the study protocol will be assessed.

Discussion

The most effective methods of supporting stroke survivors to alter physical activity and sedentary behaviour have yet to be established. This study will establish the feasibility of delivering a complex theory- and evidence-based intervention targeting the behaviour of both stroke survivors and HCPs and assess whether it is acceptable to the target populations. Findings will inform the iterative development of the intervention before a larger scale evaluation.

Active and sedentary bouts in people after stroke and healthy controls: An observational study

BACKGROUND AND PURPOSE

Understanding how both active and sedentary time is accumulated in people after stroke may help to better target interventions to reduce stroke recurrence. This study aimed to determine the difference between stroke and healthy controls in (a) time spent in sedentary and active behaviour, (b) frequency of short and long active and sedentary bouts and (c) time spent in short and long active and sedentary bouts.

METHODS

Analysis of secondary outcomes from a cross-sectional study. Participants were 42 community-dwelling people after stroke and 21 age-matched healthy controls. An activity monitor was used to collect free-living active and sedentary behaviour. Total active (standing and walking) and sedentary (lying, reclining and sitting) time was calculated in minutes per day. Bouts were categorized as short (<5 min, 5-15 min, 15-30 min) or long (>30 min). The frequency of and time spent in each bout were calculated.

RESULTS

Relative to wear time, the stroke group spent 10% (95% confidence interval [CI] 3 to 17) more time in sedentary behaviour and had fewer long active bouts than the healthy controls. The stroke group spent 7% (95% CI 1-13) less time in long active bouts and 11% (95% CI 2-20) more time in long sedentary bouts than the healthy controls.

CONCLUSIONS

Community-dwelling people after stroke spent less time in active behaviour and accumulated more sedentary time in bouts longer than 30 min compared with healthy controls. Increasing active time and breaking up long sedentary time warrants investigation in people after stroke.

German recommendations for physical activity and physical activity promotion in adults with noncommunicable diseases

Background

Existing physical activity guidelines predominantly focus on healthy age-stratified target groups. The objective of this study was to develop evidence-based recommendations for physical activity (PA) and PA promotion for German adults (18–65 years) with noncommunicable diseases (NCDs).

Methods

The PA recommendations were developed based on existing PA recommendations. In phase 1, systematic literature searches were conducted for current PA recommendations for seven chronic conditions (osteoarthrosis of the hip and knee, chronic obstructive pulmonary disease, stable ischemic heart disease, stroke, clinical depression, and chronic non-specific back pain). In phase 2, the PA recommendations were evaluated on the basis of 28 quality criteria, and high-quality recommendations were analysed. In phase 3, PA recommendations for seven chronic conditions were deducted and then synthesised to generate generic German PA recommendations for adults with NCDs. In relation to the recommendations for PA promotion, a systematic literature review was conducted on papers that reviewed the efficacy/effectiveness of interventions for PA promotion in adults with NCDs.

Results

The German recommendations for physical activity state that adults with NCDs should, over the course of a week, do at least 150 min of moderate-intensity aerobic PA, or 75 min of vigorous-intensity aerobic PA, or a combination of both. Furthermore, muscle-strengthening activities should be performed at least twice a week. The promotion of PA among adults with NCDs should be theory-based, specifically target PA behaviour, and be tailored to the respective target group. In this context, and as an intervention method, exercise referral schemes are one of the more promising methods of promoting PA in adults with NCDs.

Conclusion

The development of evidence-based recommendations for PA and PA promotion is an important step in terms of the initiation and implementation of actions for PA-related health promotion in Germany. The German recommendations for PA and PA promotion inform adults affected by NCDs and health professionals on how much PA would be optimal for adults with NCDs. Additionally, the recommendations provide professionals entrusted in PA promotion the best strategies and interventions to raise low PA levels in adults with NCDs. The formulation of specific PA recommendations for adults with NCDs and their combination with recommendations on PA promotion is a unique characteristic of the German recommendations.

Informing the training of health care professionals to implement behavior change strategies for physical activity promotion in neurorehabilitation: a systematic review

Initiatives to increase physical activity (PA) are most effective when combined with behavior change strategies (BCS). However, this is not routinely done and perhaps can be attributed to health care professionals' (HCP) lack of confidence and understanding of how to best apply BCS. This review aimed to identify and synthesize the existing literature describing methods used to train HCP to deliver BCS for PA promotion for individuals living with neurological conditions. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Eight databases were searched for articles describing how HCP were trained on BCS targeting PA and/or exercise for neurological pathology. Two researchers independently screened abstracts and used third-party consensus when needed. Studies must have described the planning/implementation of BCS targeting PA in adults with neurological disorders, with interventions delivered by a HCP. A data extraction table based on the study objective and the Cochrane Consumers and Communication Review Group's data extraction template was used. Risk of bias was assessed using the Quality Assessment Tools for Quantitative and Qualitative Studies. Included studies were also evaluated using the Workgroup for Intervention Development and Evaluation Research (WIDER) recommendations for reporting behavior change intervention content. Extraction and evaluation of risk of bias were completed independently by two researchers. Data were synthesized according to a who, what, when, and how approach. The search yielded 2,616 articles after duplicates removed, with 13 articles, representing eight unique interventions in individuals with spinal cord injury, stroke, multiple sclerosis, and Parkinson's disease included. Methodological quality ranged from strong to weak. Methods used to increase HCP knowledge and use of BCS were heterogeneous. Common training features included multiple resources, multiple sessions, expert input, and ongoing support, but a lack of evaluation of training effectiveness. The BCS were based on Social Cognitive Theory in seven interventions. Physiotherapists were the most common HCP trained. There was considerable variety in how HCP were trained to use BCS and a lack of evaluation of training effectiveness. Future work should include more description of the content and structure of HCP training and a direct measure of effectiveness. Researchers should consider implementation strategies during development and reporting of behavior change interventions. This review was not registered with PROSPERO.

Structuring community-based adapted dance programs for persons post-stroke: a qualitative study

PURPOSE

Dance improves physical, psychosocial, and cognitive function, while increasing community participation among community-dwelling individuals post-stroke. Yet little is known about how to structure community-based dance classes to optimize benefits and participation. This study aims to gain stakeholders' perspectives about how to optimally structure community-based dance classes for individuals with chronic stroke.

METHODS

A qualitative descriptive approach utilizing focus group methods was implemented. Two focus groups were undertaken with each of three stakeholder groups: persons post-stroke (n = 9), rehabilitation therapists (n = 6), and dance instructors (n = 8). Focus groups were audio-recorded and transcribed verbatim, providing the raw data. Analysis of the focus group transcripts were completed using the DEPICT model of collaborative qualitative analysis.

RESULTS

This study identified three main themes/topics requiring consideration when structuring community-based dance programs: the environment, flow of the class, and qualities of the dance instructor. The study findings highlight that the pedagogical skills and teaching philosophy of the dance instructor are integral for a successful dance program, as the dance instructor directly mediates both the environment and flow of classes.

CONCLUSION

Recommendations generated from our study can inform the development of community-based dance programs that are practical, optimize health benefits, and meet the needs and interests of people post-stroke.IMPLICATIONS FOR REHABILITATIONDance is an effective way to improve physical, psychosocial, and cognitive function for persons post-stroke while also promoting meaningful social relationships within the community.A dance instructor who is a skilled communicator and is willing to adapt to the needs of the class, is the most important factor for a successful dance class.Creating a safe and inviting environment for a dance program, includes both the physical and emotional aspects of environment facilitating individuals to create connections with others and feel more confident in themselves.The structure of a dance class, based on the abilities, interests, and goals of dancers, should include elements of predictability and variability to keep dancers progressing and motivated, and be two times a week for 3 months lasting 1-2 h.

Effect of investigator observation on gait parameters in individuals with stroke

Improvements in gait speed following various training paradigms applied to patients post-stroke does not always lead to changes in walking performance, defined as gains in daily stepping activity. We hypothesized that testing conditions, specifically the presence of an observer, influences patient behaviors and resultant outcomes may overestimate their true walking capacity. This potential Hawthorne effect on spatiotemporal and biomechanical measures of locomotor function in individuals post-stroke has not been assessed previously. Fifteen ambulatory individuals with chronic stroke wore instrumented insoles and performed two separate normal-pace walking assessments, including unobserved conditions during which participants were unattended and unaware of data collection, and observed conditions with an investigator present. Gait analysis was conducted outside of a laboratory setting using instrumented insoles equipped with a 3D accelerometer and pressure sensors which captured the spatiotemporal kinematics, vertical ground reaction forces and foot acceleration. Data were compared using paired comparisons, with subsequent correlation and stepwise regression analyses to explore potential associations between Hawthorne-induced changes in walking strategies, gait speed and locomotor performance (daily stepping). Except for cadence, other measures of spatiotemporal parameters and swing kinematics (acceleration) were not significantly different between observed vs unobserved conditions. However, analyses of ground reaction forces revealed significantly greater paretic limb loading (Δ1^st peak = 1.5 ± 1.6 N/kg Δ2^nd peak = 1.4 ± 1.8 N/kg; p < 0.01) and increases in weight bearing symmetry (11-24%, p < 0.01) during observed vs unobserved conditions. This potential Hawthorne effect was greater in those with slower walking speeds and shorter stride lengths but was not related to daily stepping. The present findings suggest that biomechanical parameters of walking function may be related to the presence of an observer and highlight the need to separately measure locomotor capacity (gait speed) and performance (daily stepping).

Randomized controlled trial of SystemCHANGE™ weight management intervention in neurological conditions

OBJECTIVE

This randomized controlled pilot study examined the feasibility and efficacy of a SystemCHANGE™ (SC) weight management intervention in adults with either multiple sclerosis or stroke.

METHODS

Participants (n = 61) were randomized into two interventions: SC, which taught skills to modify personal environments, or active-control (AC), which taught health behavior guidelines. Sessions were held weekly for 12 weeks. Feasibility measures included recruitment and attrition rates. The primary outcome of body weight and secondary outcomes of emotional well-being and healthy behaviors were measured before and after the interventions.

RESULTS

Average recruitment rate was 3.6 participants per month. Attrition rate was 14.8%. On average, 9.1 sessions were completed for SC and 10.7 for AC. Differences in weight loss were non-significant between interventions (P = 0.182), but significantly declined across both interventions (P = 0.011). Physical activity (P = 0.002), depression (P < 0.001), anxiety (P = 0.023), and self-efficacy (P = 0.022) all significantly improved for SC compared to AC.

CONCLUSIONS

SC was feasible to implement and efficacious in improving secondary outcomes of emotional well-being and healthy behaviors, but was not efficacious in improving the primary outcome of weight loss. More research is needed to optimize SC.

PRACTICE IMPLICATIONS

SC might be an alternative approach to cognitive-behavioral therapy for promoting emotional well-being and healthy behaviors.

Cost-effectiveness of physical fitness training for stroke survivors

Background Physical fitness is impaired after stroke, yet fitness training after stroke reduces disability. Several international guidelines recommend that fitness training be incorporated as part of stroke rehabilitation. However, information about cost-effectiveness is limited. Methods A decision tree model was used to estimate the cost-effectiveness of a fitness programme for stroke survivors vs. relaxation (control group). This was based on a published randomised controlled trial, from which evidence about quality of life was used to estimate Quality Adjusted Life Years. Costs were based on the cost of the provision of group fitness classes within local community centres and a cost per Quality Adjusted Life Year was calculated. Results The results of the base case analysis found an incremental cost per Quality Adjusted Life Year of £2,343. Conclusions Physical fitness sessions after stroke are a cost-effective intervention for stroke survivors. This information will help make the case for the development of new services.

The implementation of a physical activity counseling program in rehabilitation care: findings from the ReSpAct study

PURPOSE

This study aimed to evaluate the implementation of a physical activity counseling program in rehabilitation and to study heterogeneity in received counseling and investigate its association with changes in patients' physical activity outcomes.

METHODS

This prospective cohort study was conducted in 18 rehabilitation institutions. Data were collected using surveys completed by professionals (n= ±70) and patients (n = 1719). Implementation was evaluated using different process outcomes: reach, dosage, satisfaction, maintenance. Patients' physical activity outcomes included changes in total minutes/week of physical activity. Latent class analyses were conducted to identify profiles of received counseling characteristics and multilevel models were used to investigate associations with physical activity outcomes.

RESULTS

5873 Patients were provided with motivational interviewing-based counseling after rehabilitation. Professionals and patients were positive about the program. Sixteen institutions (89%) formally agreed to continue the program. The four identified profiles of counseling characteristics illustrate a large variation in received counseling among patients. No substantial differences in physical activity outcomes were found between profiles.

CONCLUSION

After a three-year program period, the physical activity counseling centers were sustainably implemented in Dutch rehabilitation care. This study illustrated an innovative approach to assess heterogeneity in implementation outcomes (e.g., counseling profiles) in relation to program outcomes (e.g., physical activity).Implications for rehabilitationPhysical activity counseling after rehabilitation is important to support people with disabilities in making the step from rehabilitation-based physical activities to community-based physical activities.Establishing "Physical Activity Counseling Centers" is a promising "disability-overarching" strategy to promote physical activity after rehabilitation.Although the actual received counseling (dosage) varied among patients, this did not coincide with large differences in physical activity outcomes.The training in Motivational Interviewing, the financial incentives, and the advisory support were considered as important or essential ingredients for a successful implementation of the counseling program in rehabilitation practice.

The stroke exercise preference inventory is feasible to use in a community rehabilitation setting

Exploring exercise preferences may help people to adhere to exercise programs by promoting customized programs to suit the person's choices and concerns. We investigated if the Stroke Exercise Preference Inventory, a questionnaire designed to explore stroke survivors' preferences for exercise and potential barriers, was feasible to use, and whether it assisted physiotherapists to design ongoing exercise programs in a mixed diagnostic convenience sample attending community rehabilitation. Physiotherapy staff interviewed 42 participants, and sought feedback about the questionnaire. Participant responses for exercise preferences and perceived barriers were then summarized. The questionnaire was quick to administer, readily understood, and considered relevant to consider when discussing options for exercise. Clinicians reported the questionnaire was useful for 48% (20/42) of participants, as it engaged the participant, clarified their preferences and allowed problem solving of potential barriers to exercise. Participants expressed strong preferences to be challenged, and to receive supervision and support. Preferences regarding environmental and social context of exercise varied widely. Difficulty getting started was the most common barrier reported. The Stroke Exercise Preference Inventory was feasible to use with a mixed diagnostic group during community rehabilitation, and provides structure to explore preferences and barriers to exercise. It remains to be tested whether use of the questionnaire promotes adherence to exercise programs.

Physical activity on prescription at the time of stroke or transient ischemic attack diagnosis - from a patient perspective

INTRODUCTION

Physical activity is known to reduce the risk of recurrent stroke. Despite this many individuals diagnosed with stroke have an insufficient level of physical activity. Physical activity on prescription is provided within healthcare to encourage increased physical activity.

PURPOSE

To examine individuals' experiences of physical activity on prescription at the time of stroke or transient ischemic attack diagnosis and explore various factors affecting the ability to follow the prescription.

MATERIAL AND METHOD

A qualitative approach was undertaken; using interviews, analyzed with content analysis to elicit information from individuals who had been admitted to a stroke unit due to stroke or transient ischemic attack.

RESULTS

Five women and five men (median age 60.5 years), eight with stroke and two with TIA (median NIHSS at onset 2.5), participated and the analysis resulted in an overall theme Change of life-style through physical activity on prescription - a multifaceted process containing the categories Experience of support, Barriers and opportunities and Personal motivators.

CONCLUSION

Individuals need to participate in the prescription process when prescription on physical activity is initiated in acute stroke care and clinicians need to reflect on how the prescription is implemented and followed-up; creating good conditions for long-term effects.IMPLICATIONS FOR REHABILITATIONWhen prescribing physical activity on prescription healthcare providers in acute stroke care need to consider:• The right timing: when and how physical activity on prescription should be given.• How to create opportunities for individuals to participate in the prescription process.• How to create individual adaptation of the prescription.• How to ensure that follow-up is conducted by registered healthcare professionals with knowledge of physical activity as disease prevention.

Virtual reality among the elderly: a usefulness and acceptance study from Taiwan

BACKGROUND

Virtual reality (VR) has several applications in the medical domain and also generates a secure environment to carry out activities. Evaluation of the effectiveness of VR among older populations revealed positive effects of VR as a tool to reduce risks of falls and also improve the social and emotional well-being of older adults. The decline in physical and mental health, the loss of functional capabilities, and a weakening of social ties represent obstacles towards active aging among older adults and indicate a need for support. Existing research focused on the effects of VR among older populations, and its uses and benefits. Our study investigated the acceptance and use of VR by the elderly.

METHODS

This pilot study was conducted on 30 older adults who voluntarily participated during March to May 2018. Nine VR applications that promote physical activities, motivate users, and provide entertainment were chosen for this study. Participants were asked to use any one of the applications of their choice for 15 min twice a week for 6 weeks. At the end of 6 weeks, participants were asked to fill out a questionnaire based on the Technology Acceptance Model and a literature review, to evaluate their acceptance of VR technology. Cronbach's alpha reliability analysis was used to test the internal consistency of the questionnaire items. Pearson's product moment correlation was used to examine the validity of the questionnaire. A linear regression and mediation analysis were utilized to identify relationships among the variables of the questionnaire.

RESULTS

In total, six male and 24 female participants aged 60~95 years volunteered to participate in the study. Perceived usefulness, perceived ease of use, social norms, and perceived enjoyment were seen to have had significant effects on the intention to use VR. Participants agreed to a large extent regarding the perceived usefulness, perceived enjoyment, and their experience of using VR. Thus, VR was seen to have high acceptance among this elderly population.

CONCLUSIONS

Older people have positive perceptions towards accepting and using VR to support active aging. They perceived VR to be useful, easy to use, and an enjoyable experience, implying positive attitudes toward adopting this new technology.

Quantitative data analysis of perceived barriers and motivators to physical activity in stroke survivors

BACKGROUND

Levels of physical activity after stroke are low, despite multiple health benefits. We explored stroke survivors' perceived barriers, motivators, self-efficacy and intention to physical activity.

METHODS

Fifty independently mobile stroke survivors were recruited prior to hospital discharge. Participants rated nine possible motivators and four possible barriers based on the Mutrie Scale, as having 'no influence', 'some influence' or 'a major influence' on physical activity. Participants also rated their self-efficacy and intention to increasing walking.

RESULTS

The most common motivator was 'physical activity is good for health' [34 (68%)]. The most common barrier was 'feeling too tired' [24 (48%)]. Intention and self-efficacy were high. Self-efficacy was graded as either 4 or 5 (highly confident) on a five-point scale by [34 (68%)] participants, while 42 (84%) 'strongly agreed' or 'agreed' that they intended to increase their walking.

CONCLUSION

Participants felt capable of increasing physical activity but fatigue was often perceived as a barrier to physical activity. This needs to be considered when encouraging stroke survivors to be more active.
