How to Address Physical Activity Participation After Stroke in Research and Clinical Practice

Integrating Cardiac Rehabilitation in Stroke Recovery

Stroke remains a top contributor to long-term disability in the United States and substantially limits a person's physical activity. Decreased cardiovascular capacity is a major contributing factor to activity limitations and is a significant health concern. Addressing the cardiovascular capacity of stroke survivors as part of poststroke management results in significant improvements in their endurance, functional recovery, and medical outcomes such as all-cause rehospitalization and mortality. Incorporation of a structured approach similar to the cardiac rehabilitation program, including aerobic exercise and risk factor education, can lead to improved cardiovascular function, health benefits, and quality of life in stroke survivors.

The Utilization of Forced-Rate Cycling to Facilitate Motor Recovery Following Stroke: A Randomized Clinical Trial

BACKGROUND

The potential for aerobic exercise (AE) to enhance neuroplasticity post-stroke has been theorized but not systematically investigated. Our aim was to determine the effects of forced-rate AE (FE) paired with upper extremity (UE) repetitive task practice (FE + RTP) compared to time-matched UE RTP (RTP only) on motor recovery.

METHODS

A single center randomized clinical trial was conducted from April 2019 to December 2022. Sixty individuals ≥6 months post-stroke with UE hemiparesis were randomized to FE + RTP (N = 30) or RTP only (N = 30), completing 90-minute sessions, 3×/week for 8 weeks. The FE + RTP group underwent 45-minute of FE (5-minute warm-up, 35-minute main set, and 5-minute cool down) followed by 45-minute of UE RTP. The RTP only group completed 90-minute of RTP. Primary outcomes were the Fugl-Meyer Assessment (FMA) and Action Research Arm Test (ARAT). The 6-minute Walk Test (6MWT, secondary outcome) assessed walking capacity.

RESULTS

Sixty individuals enrolled and 56 completed the study. The RTP only group completed more RTP in terms of repetitions (411.8 ± 44.4 vs 222.8 ± 28.4, P < .001) and time (72.7 ± 6.7 vs 37.8 ± 2.4 minutes, P < .001) versus FE + RTP. There was no significant difference between groups on the FMA (FE + RTP, 36.2 ± 10.1-44.0 ± 11.8 and RTP only, 34.4 ± 11.0-41.2 ± 13.4, P = .43) or ARAT (FE + RTP, 32.5 ± 16.6-37.7 ± 17.9 and RTP only, 32.8 ± 18.6-36.4 ± 18.5, P = .88). The FE + RTP group demonstrated greater improvements on the 6MWT (274.9 ± 122.0-327.1 ± 141.2 m) versus RTP only (285.5 ± 160.3-316.9 ± 170.0, P = .003).

CONCLUSIONS

There was no significant difference between groups in the primary outcomes. The FE + RTP improved more on the 6MWT, a secondary outcome.

What influences stroke survivors with physical disabilities to be physically active? A qualitative study informed by the Theoretical Domains Framework

BACKGROUND

Although the benefits of regular physical activity (PA) after stroke are well established, many stroke survivors do not achieve recommended PA levels. To date, studies exploring determinants to PA have not used a behaviour change theory and focused on stroke survivors with physical disabilities. As a precursor to an intervention development study, we aimed to use the Theoretical Domains Framework (TDF) to identify factors influencing PA in stroke survivors with physical disabilities in Singapore.

METHODS

Between November 2021 and January 2022, we conducted interviews with 19 community-dwelling stroke survivors with a weak arm and/or leg. An interview guide based on the TDF was developed. We analysed the data deductively by coding interview transcripts into the theoretical domains of the TDF, and then inductively by generating themes and belief statements. To identify relevant TDF domains, we prioritised the domains based on the frequencies of the belief statements, presence of conflicting belief statements and evidence of strong belief statements.

RESULTS

Eight of the 14 TDF domains were relevant, and included environmental context and resources, knowledge, social influences, emotion, reinforcement, behavioural regulation, skills and beliefs about capabilities. The lack of access, suitable equipment and skilled help often limited PA participation at public fitness spaces such as parks, gyms and swimming pools (environmental context and resources). While a few stroke survivors expressed that they had the skills to engage in regular PA, most expressed not knowing how much and how hard to work, which exercises to do, which equipment to use and how to adapt exercises and equipment (knowledge and skills). This often left them feeling afraid to try new activities or venture out to new places for fear of the unknown or adverse events (e.g., falls) (emotion). For some, doing the activities in a group encourage them to get out and engage in PA (social influences).

CONCLUSIONS

In stroke survivors with physical disabilities, environmental context and resources had a significant influence on PA participation, and this often had a spill over effect into other domains. Our results inform a complex behaviour change intervention to improve PA after stroke, and has implications for intervention design for people with physical disabilities.

Factors That Influence Meeting the Recommended Weekly Physical Activity Target Among Older People With Physical Multimorbidity: Evidence From 6 Low- and Middle-Income Countries

BACKGROUND

There is a scarcity of studies on the association between physical multimorbidity and lower levels of physical activity among older adults from low- and middle-income countries, while the potential mediating variables in this association are largely unknown.

METHODS

Cross-sectional, community-based, nationally representative data from the World Health Organization Study on global AGEing and adult health were analyzed. Data on 11 chronic physical conditions were collected. Scoring <150 minutes of moderate- to high-intensity physical activity per week was considered low physical activity. Multivariable logistic regression and mediation analysis were done to assess associations and quality of life measures which might influence these associations.

RESULTS

Data on 14,585 people aged ≥65 years were analyzed (mean [SD] age 72.6 (11.5) y, maximum age 114 y; 55.0% women). After adjustment for potential confounders, compared with no chronic conditions, ≥3 conditions were associated with a significant 1.59 to 2.42 times higher odds for low physical activity. Finally, mobility mediated the largest proportion of the association between ≥3 chronic physical conditions and low physical activity (mediated percentage 50.7%), followed by activities of daily living disability (30.7%), cognition (24.0%), affect (23.6%), and pain/discomfort (22.0%).

CONCLUSIONS

Physical multimorbidity was associated with higher odds for low physical activity among older adults residing in low- and middle-income countries. Mobility, disability, cognition, affect, and pain/discomfort explained the largest proportion of this association. Given the universal benefits of regular and sustained participation in physical activity, it would be prudent to implement interventions among older people with physical multimorbidity to increase levels of physical activity. Future studies should assess the impact of addressing the identified potential mediators among people with multimorbidity on physical activity levels.

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.

Evaluation of a carepartner-integrated telehealth gait rehabilitation program for persons with stroke: study protocol for a feasibility study

BACKGROUND

Despite family carepartners of individuals post-stroke experiencing high levels of strain and reduced quality of life, stroke rehabilitation interventions rarely address carepartner well-being or offer training to support their engagement in therapeutic activities. Our group has developed creative intervention approaches to support families during stroke recovery, thereby improving physical and psychosocial outcomes for both carepartners and stroke survivors. The purpose of this study is to test the feasibility of an adapted, home-based intervention (Carepartner Collaborative Integrative Therapy for Gait-CARE-CITE-Gait) designed to facilitate positive carepartner involvement during home-based training targeting gait and mobility.

METHODS

This two-phased design will determine the feasibility of CARE-CITE-Gait, a novel intervention that leverages principles from our previous carepartner-focused upper extremity intervention. During the 4-week CARE-CITE-Gait intervention, carepartners review online video-based modules designed to illustrate strategies for an autonomy-supportive environment during functional mobility task practice, and the study team completes two 2-h home visits for dyad collaborative goal setting. In phase I, content validity, usability, and acceptability of the CARE-CITE-Gait modules will be evaluated by stroke rehabilitation content experts and carepartners. In phase II, feasibility (based on measures of recruitment, retention, intervention adherence, and safety) will be measured. Preliminary effects of the CARE-CITE-Gait will be gathered using a single-group, quasi-experimental design with repeated measures (two baseline visits 1 week apart, posttest, and 1-month follow-up) with 15 carepartner and stroke survivor dyads. Outcome data collectors will be blinded. Outcomes include psychosocial variables (family conflict surrounding stroke recovery, strain, autonomy support, and quality of life) collected from carepartners and measures of functional mobility, gait speed, stepping activity, and health-related quality of life collected from stroke survivors.

DISCUSSION

The findings of the feasibility testing and preliminary data on the effects of CARE-CITE-Gait will provide justification and information to guide a future definitive randomized clinical trial. The knowledge gained from this study will enhance our understanding of and aid the development of rehabilitation approaches that address both carepartner and stroke survivor needs during the stroke recovery process.

Mapping physical activity patterns in hospitalised patients with moderate to severe acquired brain injury - MAP-ABI: Protocol for an observational study

Introduction

The physical activity level in patients hospitalised for rehabilitation across multiple diagnoses is low. Moderate to severe acquired brain injury further reduces activity levels as impaired physical and cognitive functioning affect mobility independence. Therefore, supervised out-of-bed mobilisation and physical activity training are essential rehabilitation strategies. Few studies have measured the physical activity patterns in the early phases of rehabilitation after moderate to severe brain injury.

Objectives

To map and quantify physical activity patterns in patients admitted to brain injury rehabilitation. Further, to investigate which factors are associated with activity and if the early physical activity level is associated with functional outcome at discharge.

Methods

This observational study includes patients admitted to rehabilitation after moderate to severe acquired brain injury. Mobility and physical activity patterns are measured continuously during rehabilitation at two separate seven-day periods using a wearable activity tracker. Activity will be categorised into four levels and presented descriptively. Linear and logistic regression models will analyse associations between descriptive variables and activity levels.

Discussion

This protocol describes an observational study investigating patients' mobility and physical activity patterns with moderate to severe acquired brain injury during in-hospital rehabilitation. The ability to increase the amount of mobilisation and physical activity in subgroups may have profound consequences on the rehabilitation outcome. Furthermore, data from this study may be used to inform a large variety of trials investigating physical rehabilitation interventions. (NCT05571462).

Effects of physical fitness training on the mental and physical health of stroke survivors

After a stroke, physical activity can be key in enhancing the rehabilitation of patients and preventing a secondary stroke. In this commentary, we critically appraise a systematic review which investigated how different types of physical fitness training impact on the mental and physical conditions of stroke survivors. Cardiorespiratory, resistance and mixed training (especially when including walking) can improve key outcomes such as the balance and mobility of stroke survivors, but the most suitable type of training depends on the individual needs and aims of the rehabilitation process. More research is needed to understand how the effects of the different types of training vary by considering the time between stroke and intervention onset, stroke severity, and the dose of intervention.

Multidimensional analysis of sedentary behaviour and participation in Spanish stroke survivors (Part&Sed-Stroke): a protocol for a longitudinal multicentre study

INTRODUCTION

Stroke survivors usually experience long-lasting functional, emotional and social consequences that might contribute to sedentary behaviour and participation restrictions, which are important targets to address during rehabilitation. However, the trajectory and inter-relationship between these factors are unknown.

METHODS AND ANALYSIS

Part&Sed is a research project based on an observational study design with 6 and 12 months of follow-ups in stroke survivors. In addition, a qualitative analysis of the impact of the stroke on the stroke survivor, validation of the Satisfaction with Daily Occupation-Occupational Balance assessment tool and analysis of the reliability of the Fitbit Inspire 2 activity tracker wristband will be carried out. Participants will be chronic stroke survivors with independent walking capacity. Sociodemographic and clinical data, physical activity, ambulation, sleep, quality of life, anxiety and depression, community participation, and occupational satisfaction and balance, as well as data provided by the activity tracker wristband, will be collected. In addition, if the participant has a primary caregiver, the caregiver will also be monitored. A minimum of 130 participants will be recruited to conduct a random-effects multiple regression model. Mixed models for repeated measures will assess the variation over time of the different variables associated with participation and sedentary behaviour. Psychometric properties (eg, internal consistency, construct validity, test-retest reliability) of the Satisfaction with Daily Occupation-Occupational Balance will be determined. Additionally, intraclass correlation coefficients and minimum detectable change will be calculated to assess intrasubject reliability of physical activity and sleep parameters recorded by the Fitbit Inspire 2. The qualitative analysis process will be carried out using the analysis proposed by Giorgi.

ETHICS AND DISSEMINATION

The study received ethical approval from the Spanish Regional Ethics Committee 'Comité de Ética de la Investigación de la Comunidad de Aragón' (PI21/333). The results will be made available via peer-reviewed publications, international conferences and official channels.

Exercise prescription, intervention, dissemination, and implementation following transient ischemic attack or stroke: advancing the field through interdisciplinary science

Research has demonstrated that both exercise, and a reduction in cardiovascular disease (CVD) risk factors (i.e., high blood sugar, blood lipids, and blood pressure), following a stroke or transient ischemic attack (TIA) are beneficial for reducing risk of recurrent stroke or TIA and for improving overall quality of life. Despite this evidence, many stroke and TIA survivors remain inactive and sedentary and present with multiple CVD risk factors. The purpose of this commentary is to highlight gaps in the current literature in regard to exercise and behavior interventions for the stroke and TIA populations, present ideas for intervention design, and discuss the dissemination and implementation of research findings. The future research ideas presented in this commentary are based on current research findings, as well as the professional experience of the article authors. Professional experience spans occupational therapy in neurorehabilitation, clinical exercise physiology in rehabilitation, creation and implementation of stroke rehabilitation clinics, stroke and TIA research, and behavioral and implementation science.

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.

Identity, social engagement and community participation impact physical activity levels of stroke survivors: A mixed-methods study

Objective

To explore how personal characteristics and social engagement impact the physical activity levels of chronic stroke survivors.

Design

A mixed-methods study comprising in-depth semi-structured interviews and objective 24-h physical activity monitoring. Interviews were thematically analysed, and activity diaries were compared to activity monitor data to attain a complete picture of physical activity. Triangulation explored the relationship between perceptions, beliefs, activity levels and social engagement.

Setting

Community.

Participants

Community-dwelling, independently mobile, adult stroke survivors (n = 19). The mean age was 74 (11 SD) years, 52% female, mean time post-stroke 41 (SD 61) months.

Main measures

Qualitative and quantitative measures including individual semi-structured interviews, accelerometry, activity diaries, self-efficacy, Frenchay Activities Index and Barthel Index.

Results

Individual identity had the greatest perceived influence on post-stroke physical activity. Pre-stroke identity, meaningful activities and family culture contributed to identity; while social and community activities, self-efficacy, co-morbidities, stroke symptoms and exercise, also impacted physical activity. Participants averaged 5365 (IQR 3378–7854) steps per day and reported a mean self-efficacy for exercise score of 51 (SD 20). Triangulation showed convergent relationships between post-stroke physical activity levels and participant motivation, comorbidities, level of social and community participation, self-efficacy and pre-stroke activity levels.

Conclusion

Personal identity, social engagement and community participation are important factors to consider when implementing a person-centred approach to increasing physical activity participation post-stroke.

Stroke survivors' perceptions of the factors that influence engagement in activity outside dedicated therapy sessions in a rehabilitation unit: A qualitative study

OBJECTIVE

To investigate stroke survivors' perceptions of factors influencing their engagement in activity outside of dedicated therapy sessions during inpatient rehabilitation.

DESIGN

Qualitative study.

SETTING

Four metropolitan rehabilitation units in Australia.

PARTICIPANTS

People undertaking inpatient rehabilitation after stroke.

METHODS

Semi-structured interviews conducted in person by a speech pathologist A stepped iterative process of inductive analysis was employed until data saturation was achieved with themes then applied against the three domains of the Theory of Planned Behaviour (perceived behavioural control, social norms and attitude).

RESULTS

Interviews of 33 stroke survivors (60% female, median age of 73 years) revealed five themes (i) uncertainty about how to navigate and what was available for use in the rehabilitation unit restricts activity and (ii) post-stroke mobility, fatigue and pre- and post-stroke communication impairments restrict activity (perceived behavioural control); (iii) unit set up, rules (perceived and actual) and staff expectations influence activity and (iv) visiting family and friends are strong facilitators of activity (social norms), and (v) personal preferences and mood influence level of activity (attitude).

CONCLUSION

At the individual level, stroke survivors perceived that their ability to be active outside of dedicated therapy sessions was influenced by their impairments, including mood, and their attitude towards and preference for activity. At the ward level, stroke survivors perceived that their ability to be active was influenced by ward set-up, rules and staff expectations. Visitors were perceived to be important facilitators of activity outside of therapy sessions.
