The effectiveness of group exercise for improving activity and participation in adult stroke survivors: a systematic review

How effective are allied health group interventions for the management of adults with long-term conditions? An umbrella review of systematic reviews and its applicability to the Australian primary health system

BACKGROUND

Group allied health interventions for people with chronic conditions may be a solution to increasing access to allied health in primary care. This umbrella review aimed to determine the effectiveness of allied health group interventions to improve health-related outcomes for adults with chronic conditions and the applicability of the findings to the Australian primary health care context.

METHODS

An umbrella review of systematic reviews conducted April-July 2022, searching eight databases. Systematic reviews were eligible if they included randomised controlled trials (RCT) or quasi-RCTs, community dwelling adults aged ≥ 18, at least one chronic condition, group intervention in scope for allied health professionals, and published in English after 2000. Studies were excluded if interventions were conducted in hospital or aged care facilities, out of scope for allied health, or unsupervised.

RESULTS

Two thousand three hundred eighty-five systematic reviews were identified: after screening and full text review 154 were included and data extracted from 90. The chronic conditions included: cancer (n = 15), cardiovascular disease (n = 6), mixed chronic conditions (n = 3), kidney disease (n = 1), low back pain (n = 12), respiratory disease (n = 8), diabetes (n = 14), heart failure (n = 9), risk of falls (n = 5), hypertension (n = 4, osteoarthritis (n = 6) and stroke (n = 8). Most group interventions included prescribed exercise and were in scope for physiotherapists and exercise physiologists. Overall, allied health group exercise programs for community dwelling adults improved health outcomes for most chronic conditions. Aggregated data from the systematic reviews suggests programs of 45-60 min per session, 2-3 times per week for 12 weeks. Lifestyle education and support for people with type-2 diabetes improved glycaemic control.

CONCLUSIONS

Prescribed group exercise delivered by allied health professionals, predominantly by exercise physiologists and physiotherapists, significantly improved health outcomes for community dwelling adults with a broad range of chronic conditions.

Community-based group rehabilitation program for stroke patients with dysphagia on quality of life, depression symptoms, and swallowing function: a randomized controlled trial

BACKGROUND

Community-based exercise programs have demonstrated potential for implementation in older adults; however, it remains imperative to ascertain whether this strategy will yield comparable benefit in stroke patients with dysphagia.

METHODS

This was a single blinded, randomized, matched pairs clinical trial. Sixty-four stroke patients with dysphagia were recruited from patients who had been discharged the Rehabilitation Department of the Third Affiliated Hospital of Sun Yat-sen University. A single blinded, randomized and controlled trial was conducted. Participants were randomly assigned to either the intervention group (n = 32) or the control group (n = 32). Patients in the intervention group received health education followed by swallowing function training in community public spaces for 5 days every week over an eight-week period (60 minutes per day). Patients in the control group received swallowing rehabilitation training, and booster educational information about dysphagia, as well as instructions on how to improve quality of life. Swallowing function (Functional Oral Intake Scale (FOIS) and Standardized Swallowing Assessment (SSA)), depressive symptoms (Geriatric Depression Scale-15), and quality of life (Swallowing-Quality of Life, SWAL-QOL) were assessed before and after all the treatment.

RESULTS

Before treatment, the two groups did not differ statistically. After the intervention, the swallowing function (SSA and FOIS) showed a significant improvement in both groups (All p < 0.001). But there was no significant difference in Functional Oral Intake Scale change between groups (P = 0.479). Compared with the control group, the intervention group had a significant improvement in depressive symptoms (P = 0.002), with a greater reduction in the number of depressed patients (13 to 6).The control group showed no significant improvements in depressive symptoms or a reduction in the number of depressed patients before and after treatment (P = 0.265, 14 to 12). The Swallowing-Quality of Life scores showed significant improvement in both the intervention and control group (P < 0.001). Specifically within Swallowing-Quality of Life sub-domains, greater changes were observed in symptoms and frequency (P < 0.001), communication (P = 0.012), and sleep (P = 0.006) for participants in the intervention group. And the cost-effectiveness of group rehabilitation surpasses that of rehabilitation training.

CONCLUSION

Community-based group rehabilitation program is more effective than traditional treatment in improving patients' depressive symptoms and quality of life, as well as being more cost-effective.

Standardized circuit class group training versus individualized goal-directed group training to improve upper limb function in stroke survivors during in-patient rehabilitation: a pragmatic trial

PURPOSE

To investigate the usability and effectiveness of standardized circuit class group training (CCT) compared to individualized goal-directed group training (GDT) in subacute stroke survivors.

MATERIALS AND METHODS

This study consists of three parts. Part 1 involved a pragmatic, non-randomized controlled trial with subacute participants and their therapists, who participated in four weeks either CCT or GDT. Superiority of the intervention was defined as significantly larger improvement on the Motor Activity Log for patients and lower workload for therapists. In Part 2, six additional workstations were developed for CCT. Part 3 replicated the study of Part 1 with the expanded CCT.

RESULTS

Part 1 showed no difference in effectiveness between training methods. CCT did not match the rehabilitation goals of the patient sufficiently, however mental workload seemed lower for therapists. An expansion of CCT could improve the match between the patient's goals and the training (Part 2). Results of Part 3 showed again no difference in effectiveness between methods. CCT was however perceived as less engaging compared to GDT, but mental load for therapists remained lower.

CONCLUSIONS

A standardized training could reduce the mental workload for therapists, but patients seemed less engaged. A combination of both might be most beneficial.Trial registration: Dutch Trial Register: NL8844 and NL9471IMPLICATIONS FOR REHABILITATIONProviding a standardized training program after stroke reduces therapists' mental workload.Individualized goal-directed group training results in the best achievement of rehabilitation goals.A combination of standardized and individual training would use best of both intervention modalities.Patients should be involved in the co-creation developing process of training programs.

Does Intradialytic Group Exercise Programme Influence Patient-Reported Outcomes, Laboratory Parameters, and Anthropometric Parameters in Maintenance Hemodialysis Patients? A Single-Group Repeated-Measures Trial

BACKGROUND

Maintenance hemodialysis(MHD) patients often suffer from fatigue and are recommended to undertake physical activities. The optimal format of exercise rehabilitation for MHD patients remains uncertain despite demonstrated health benefits. This study aimed to evaluate the effectiveness of an intradialytic group exercise programme for MHD patients.

METHODS

This was a single-centre, single-group repeated-measures design study. The 12-week, three times per-week intradialytic group exercise programme was conducted for around 30 min during the first 2 hours of each dialysis session. Patient-reported outcomes including fatigue, anxiety, depression and health-related quality of life, laboratory parameters including haemoglobin, albumin, pre-albumin and hypersensitive C-reactive protein, and anthropometric parameters including triceps skinfold thickness, mid-upper arm circumference, mid-arm muscle circumference and handgrip strength, were measured at baseline, immediately post-intervention and 12-weeks post-intervention. The repeated-measures analysis of variance and Friedman test were used to compare the parametric and non-parametric data across time points, respectively.

RESULTS

Ninety patients were enrolled and 75 completed. Participants reported significant improvements across time points in fatigue (F = 10.19, p < 0.01), depression (F = 19.20, p < 0.001), health-related quality of life (F = 5.36, p = 0.006), haemoglobin (F = 3.43, p = 0.047), albumin (F = 4.42, p = 0.032), hypersensitive C-reactive protein (χ ² = 50.39, p < 0.001), pre-albumin (χ ² = 11.85, p = 0.003), triceps skinfold thickness (F = 25.03, p < 0.001), mid-upper arm circumference (F = 6.32, p = 0.005), mid-arm muscle circumference (F = 4.89, p = 0.02), and handgrip strength (F = 13.59, p < 0.001). Although the mean anxiety score tended to reduce, the difference across time points was nonsignificant (F = 1.33, p = 0.27).

CONCLUSION

The findings suggested that the intradialytic group exercise programme could improve MHD patients' fatigue, depression, health-related quality of life, nutritional status, and inflammation.

What Is Intensity and How Can It Benefit Exercise Intervention in People With Stroke? A Rapid Review

Background: Stroke is one of the major causes of chronic physical disability in the United Kingdom, typically characterized by unilateral weakness and a loss of muscle power and movement coordination. When combined with pre-existing comorbidities such as cardiac disease and diabetes, it results in reductions in cardiovascular (CV) fitness, physical activity levels, functional capacity, and levels of independent living. High-intensity training protocols have shown promising improvements in fitness and function for people with stroke (PwS). However, it remains unclear how intensity is defined, measured, and prescribed in this population. Further, we do not know what the optimal outcome measures are to capture the benefits of intensive exercise. Aim: To understand how intensity is defined and calibrated in the stroke exercise literature to date and how the benefits of high-intensity training in PwS are measured. Methods: A rapid review of the literature was undertaken to provide an evidence synthesis that would provide more timely information for decision-making (compared with a standard systematic review). Electronic databases were searched (including Medline, PubMed, CINAHL, and Embase for studies from 2015 to 2020). These were screened by title and abstract for inclusion if they: (a) were specific to adult PwS; and (b) were high-intensity exercise interventions. Eligible studies were critically appraised using the Mixed Method Appraisal Tool (MMAT). The data extraction tool recorded the definition of intensity, methods used to measure and progress intensity within sessions, and the outcomes measure used to capture the effects of the exercise intervention. Results: Seventeen studies were selected for review, 15 primary research studies and two literature reviews. Sixteen of the 17 studies were of high quality. Nine of the primary research studies used bodyweight-supported treadmills to achieve the high-intensity training threshold, four used static exercise bikes, and two used isometric arm strengthening. Five of the primary research studies had the aim of increasing walking speed, five aimed to increase CV fitness, three aimed to improve electroencephalogram (EEG) measured cortical evoked potentials and corticospinal excitability, and two investigated any changes in muscle strength. Although only one study gave a clear definition of intensity, all studies clearly defined the high-intensity protocol used, with most (15 out of 17 studies) clearly describing threshold periods of high-intensity activity, followed by rest or active recovery periods (of varying times). All of the studies reviewed used outcomes specific to body structure and function (International Classification of Functioning, Disability, and Health (ICF) constructs), with fewer including outcomes relating to activity and only three outcomes relating to participation. The reported effect of high-intensity training on PwS was promising, however, the underlying impact on neurological, musculoskeletal, and CV systems was not clearly specified. Conclusions: There is a clear lack of definition and understanding about intensity and how thresholds of intensity in this population are used as an intervention. There is also an inconsistency about the most appropriate methods to assess and provide a training protocol based on that assessment. It remains unclear if high-intensity training impacts the desired body system, given the diverse presentation of PwS, from a neuromuscular, CV, functional, and psychosocial perspective. Future work needs to establish a clearer understanding of intensity and the impact of exercise training on multiple body systems in PwS. Further understanding into the appropriate assessment tools to enable appropriate prescription of intensity in exercise intervention is required. Outcomes need to capture measures specific not only to the body system, but also level of function and desired goals of individuals.

"Just Going to a Spin Class": Participant Experiences of Inclusion Within an Integrated Indoor Cycling Program

Justifications for access to physical activity for people who experience disability tend to focus on the health benefits associated with a medical model of disability. The result is often programs that are segregated and impairment-focused, with limited access to integrated settings that are also potentially inclusive. In this instrumental case study, the authors engaged 20 participants with and without impairment from an adult integrated indoor cycling program to explore what contributed to meaningful and inclusive experiences in this setting. Data were generated through semistructured interviews and reflective notes. Thematic analysis led to three themes: (a) "just going to a spin class" (b) "seamless"? and (c) "deliberate community." Using a relational ethics framework, the findings are discussed with regard to their potential to inform the development of integrated and inclusive physical activity programs, with emphasis on program structure and instructor reflexivity and training.

Stroke survivors' experiences with rebuilding life in the community and exercising at home: A qualitative study

Aim

This study aimed to explore how stroke survivors deal with stroke‐related impairments when rebuilding their lives in the community and their experiences of exercising at home.

Design

An explorative and descriptive qualitative study.

Methods

A purposive sample of ten stroke survivors residing at home was recruited to explore experiences of rebuilding their lives in the community and exercising at home. One focus group interview was conducted followed by semi‐structured interviews. Data were analysed using thematic analysis.

Results

Three main themes were identified: “Framing exercise within the context of everyday life” describes how stroke survivors integrate exercise in everyday activities with varying success and the social importance of exercising; “Managing the challenges of physical impairment” describes the taxing undertakings in daily living, loss of concentration and identity; “Long‐term challenges of everyday life” describes how the stroke survivors manage depression and live with a sense of uncertainty.

Effectiveness of Upper Limb Wearable Technology for Improving Activity and Participation in Adult Stroke Survivors: Systematic Review

BACKGROUND

With advances in technology, the adoption of wearable devices has become a viable adjunct in poststroke rehabilitation. Upper limb (UL) impairment affects up to 77% of stroke survivors impacting on their ability to carry out everyday activities. However, despite an increase in research exploring these devices for UL rehabilitation, little is known of their effectiveness.

OBJECTIVE

This review aimed to assess the effectiveness of UL wearable technology for improving activity and participation in adult stroke survivors.

METHODS

Randomized controlled trials (RCTs) and randomized comparable trials of UL wearable technology for poststroke rehabilitation were included. Primary outcome measures were validated measures of activity and participation as defined by the International Classification of Functioning, Disability, and Health. Databases searched were MEDLINE, Web of Science (Core collection), CINAHL, and the Cochrane Library. The Cochrane Risk of Bias Tool was used to assess the methodological quality of the RCTs and the Downs and Black Instrument for the quality of non RCTs.

RESULTS

In the review, we included 11 studies with collectively 354 participants at baseline and 323 participants at final follow-up including control groups and participants poststroke. Participants' stroke type and severity varied. Only 1 study found significant between-group differences for systems functioning and activity (P≤.02). The 11 included studies in this review had small sample sizes ranging from 5 to 99 participants at an average (mean) age of 57 years.

CONCLUSIONS

This review has highlighted a number of reasons for insignificant findings in this area including low sample sizes and the appropriateness of the methodology for complex interventions. However, technology has the potential to measure outcomes, provide feedback, and engage users outside of clinical sessions. This could provide a platform for motivating stroke survivors to carry out more rehabilitation in the absence of a therapist, which could maximize recovery.
