Regenerate: assessing the feasibility of a strength-training program to enhance the physical and mental health of chronic post stroke patients with depression

The effect of exercise interventions on reducing the risk of depressive and cognitive disorders in post-stroke-a systematic review and meta-analysis

Background

Stroke patients often experience sequelae such as depressive symptoms, cognitive impairment, and abnormal physical function. Exercise intervention may be an effective and safe non-drug treatment to address these health issues.

Objective

The aim of this meta-analytical review was to explore the effects of exercise intervention programs on depressive symptoms, cognitive function, physical function, and quality of life in stroke patients, as well as to identify appropriate exercise programs.

Methods

Seven databases were searched from the library's construction until 30 August 2024. A meta-analysis was performed, and the risk of bias was assessed using Review Manager 5.4. Sensitivity analysis was conducted using Stata 16.0 software, and the overall certainty of the evidence was rated using Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methods.

Results

A total of 11,607 studies were identified. Among these, 20 studies, which included 1,848 patients, were considered eligible for this network meta-analysis. Compared to the control group, exercise significantly improved cognitive function (standard mean difference [SMD] = 1.08, 95% confidence interval [CI] = 0.40-1.75, p = 0.002), physical balance ability (mean difference [MD] = 0.80, 95% CI = 0.23-1.37, p < 0.01), physical walking ability (MD = 48.39, 95% CI = 8.06-88.72, p = 0.02), and quality of life. However, exercise had no significant effect on depressive symptoms (SMD = -0.2, 95% CI = -0.46-0.05, p = 0.11). A subgroup analysis indicated that a longer duration of exercise (> 3 months) can effectively improve depressive symptoms in stroke patients.

Conclusion

The results indicated that cognitive function, balance, walking speed, and quality of life of stroke patients improved following exercise intervention, and longer exercise duration (> 3 months) contributed to alleviating the depressive symptoms of stroke patients. Therefore, we recommend that stroke patients engage in physical exercise 3 times a week for 1 h each session. The exercise duration should continue for at least 3 months to ensure the best therapeutic effect. Furthermore, determining exercise intensity should be a personalized process-carefully customized to align with the physical capabilities and limitations of each patient.

The effects of exercise interventions on depressive symptoms in stroke patients: a systematic review and meta-analysis

Purpose

This systematic review and meta-analysis aimed to evaluate the effects of exercise interventions on depressive symptoms in stroke patients.

Methods

Following PRISMA guidelines, We conducted searches in PubMed, Embase, CENTRAL, and Web of Science. The topic was the effect of exercise on depression levels in stroke patients. Patient's performance on depression scales after exercise was assessed using standardized mean difference (SMD) and 95% confidence intervals (95% CI). A random effects model (RE) was used to conduct a meta-analysis and compare the results between subgroups conducted based on adherence to ACSM guidelines and the length of exercise interventions.

Results

The analysis included 24 randomized controlled trials (RCTs) involving 1,757 participants. The meta-analysis revealed that exercise interventions had a significant positive effect on reducing depressive symptoms in stroke patients, with a standardized mean difference (SMD) of -0.43 (95% CI: 0.65, -0.21). Subgroup analysis indicated that high compliance with ACSM guidelines resulted in a more substantial reduction in depressive symptoms (SMD = -0.79, 95% CI: 1.10, -0.49), compared with low or uncertain compliance (SMD = -0.03, 95% CI: 0.16, 0.10). Longer exercise intervention was associated with greater mitigation of depressive symptoms. The differences between intervention groups of different lengths were statistically significant (p < 0.05).

Conclusion

These findings support the integration of tailored exercise programs into post-stroke care to optimize mental health outcomes. Compliance to ACSM-recommended exercise dosages significantly ameliorate depression levels in stroke patients. Further research is warranted to explore standardized exercise regimens in larger, multicenter trials.

Effects of Exercise on Post-Stroke Depression: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Numerous studies have investigated the effects of exercise on post-stroke depression (PSD), yet the findings remain inconclusive. This study aims to evaluate the impact of exercise on depressive symptoms in stroke patients and to identify the most effective exercise protocols for this population. A systematic review of the Embase, PubMed, Cochrane Library, Web of Science, and Scopus databases was conducted, with a search cutoff date of 13 September 2024. Quantitative synthesis was employed to assess the intervention effects, with effect sizes expressed as standardized mean differences (SMDs) and 95% confidence intervals to evaluate the efficacy of exercise in alleviating PSD. A total of 24 studies met the inclusion criteria. The results indicated that exercise significantly alleviated depressive symptoms in stroke patients (SMD = -0.18; p = 0.007). Specifically, multicomponent training emerged as the most effective intervention for reducing depression (SMD = -0.24; p = 0.008). Additionally, exercise programs with a duration of ≥12 weeks (SMD, -0.17; p = 0.04), ≥3 sessions per week (SMD, -0.20; p = 0.02), <60 min per session (SMD, -0.19; p = 0.05), and <180 min per week (SMD, -0.27; p = 0.02) were found to be the most effective in alleviating PSD. Exercise represents an effective strategy for managing PSD, with multicomponent training potentially serving as the optimal intervention. These findings provide evidence for clinicians, recommending that stroke patients engage in exercise at least three times weekly, with individual sessions not exceeding 60 min. By increasing the frequency of exercise, the cumulative weekly time should ideally remain below 180 min for optimal outcomes.

Prescribing strength training for stroke recovery: a systematic review and meta-analysis of randomised controlled trials

OBJECTIVE

To examine the effects of strength training on patient-important outcomes of stroke recovery and to quantify the influence of the exercise prescription on treatment effects.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Eight electronic databases (MEDLINE, EMBASE, EMCARE, AMED, PsycINFO, CINAHL, SPORTDiscus, and Web of Science) and two clinical trial registries (ClinicalTrials.gov and WHO International Clinical Trials Registry Platform) were searched from inception to 19 June 2024.

ELIGIBILITY CRITERIA

Randomised controlled trials were eligible if they examined the effects of strength training compared with no exercise or usual care and reported at least one exercise prescription parameter. An advisory group of community members with lived experience of stroke helped inform outcomes most relevant to stroke recovery.

RESULTS

Forty-two randomised trials (N=2204) were included. Overall risk of bias was high across most outcomes. Strength training improved outcomes rated as 'critical for decision-making' by the advisory group, including walking capacity (standardised mean difference (SMD)=0.95 (95% CI 0.34-1.56)), balance (SMD=1.13 (0.51-1.75)), functional ability and mobility (SMD=0.61 (0.09-1.14)), and habitual (mean difference (MD)=0.05 m/s (0.02-0.09)) and fast-paced walking speed (MD=0.09 m/s (0.01-0.17)), with very low to moderate certainty of evidence, mainly due to risk of bias and inconsistency. More frequent strength training, traditional strength training programmes and power-focused intensities (ie, emphasis on movement velocity) were positively associated with walking capacity, health-related quality of life and fast-paced walking speed.

CONCLUSION

Strength training alone or combined with usual care improves stroke recovery outcomes that are important for decision-making. More frequent strength training, power-focused intensities and traditional programme designs may best support stroke recovery.

The effect of exercise on depression and gut microbiota: Possible mechanisms

Exercise can effectively prevent and treat depression and anxiety, with gut microbiota playing a crucial role in this process. Studies have shown that exercise can influence the diversity and composition of gut microbiota, which in turn affects depression through immune, endocrine, and neural pathways in the gut-brain axis. The effectiveness of exercise varies based on its type, intensity, and duration, largely due to the different changes in gut microbiota. This article summarizes the possible mechanisms by which exercise affects gut microbiota and how gut microbiota influences depression. Additionally, we reviewed literature on the effects of exercise on depression at different intensities, types, and durations to provide a reference for future exercise-based therapies for depression.

Effectiveness of multifaceted interventions including motivational interviewing and home-based rehabilitation program for improving mental and physical health in stroke patients: A randomized controlled trial

Background

In Vietnam, early screening and intervention for post-stroke mental health are limited, with rising demand for home-based rehabilitation due to the scarcity of inpatient programs.

Objectives

We aimed to evaluate the effectiveness of multifaceted interventions, including Motivational Interviewing and home-based rehabilitation, in improving the mental and physical health of stroke patients.

Design

A randomized controlled trial at the Vietnam National Geriatric Hospital assessed a multi-intervention approach for stroke survivors from 2021 to 2022. Ninety-two participants (aged over 45 with a stroke diagnosis) were randomly assigned to an intervention group (Motivational Interviewing and home-based rehabilitation) or a control group (standard care), with 46 participants in each group. Outcomes for mental health (Patient Health Questionnaire-9, Fatigue Severity Scale, Mini-Mental State Examination) and physical health (Barthel Index) were measured at baseline and after 1, 3, and 6 months. Statistical analyses used t-tests, Cohen's d, and repeated measures ANOVA.

Results

Over 6 months, 37 participants completed the intervention program. Baseline characteristics were similar except for age, lesion locations, and National Institutes of Health Stroke Scale scores. The intervention group showed significant improvements in mental health and physical function. Patient Health Questionnaire-9 scores decreased from 9.1 to 1.8, and Fatigue Severity Scale scores dropped from 28.5 to 17.8, while Barthel Index scores improved from 58.8 to 68.8 (p < 0.001).

Conclusions

We found that participants who underwent Motivational Interviewing therapy and home-based rehabilitation were more likely than those receiving standard care to experience substantial improvements in both mental and physical health metrics.

Registration

The research protocol was registered on ClinicalTrials.gov on August 1, 2021 (Identifier: NCT04941482, link: https://clinicaltrials.gov/study/NCT04941482).

Advances in Exercise in the Clinical Trials of Migraine: A Scoping Review

PURPOSE OF REVIEW

This review aimed to investigate emerging evidence regarding the effectiveness of exercise for migraines, focusing on the results of recent trials. Additionally, it explored the possibility of exercise as a treatment for migraines.

RECENT FINDINGS

Between 2020 and 2023, five, four, one, and two trials were conducted regarding the effect of aerobic exercise, anaerobic exercise, Tai Chi, and yoga, respectively, on migraine; all studies showed significant effects. Two trials on aerobic exercise showed that high-intensity exercise was similar to or slightly more effective than moderate-intensity exercise as a treatment for migraines. Three trials on anaerobic exercise reported its effectiveness in preventing migraines. Regarding efficacy, side effects, and health benefits, aerobic exercises and yoga are potentially beneficial strategies for the prevention of migraines. Further studies are needed to develop evidence-based exercise programs for the treatment of migraines.

Can resistance training improve mental health outcomes in older adults? A systematic review and meta-analysis of randomized controlled trials

Purpose This systematic review and meta-analysis aimed to analyze the effects of resistance training (RT) and to compare the different RT prescriptions, sample characteristics, and mental health outcomes (depressive and anxiety symptoms) in older adults. Methods All studies that were available on 28th April 2023. For the analysis of intervention effects on depressive and anxiety symptoms, standardized mean differences and standard errors were calculated. Meta-analyses using random-effects models, employing robust variance meta-regression for multilevel data structures, with adjustments for small samples. Results For depressive symptoms, the mean effect was - 0.94 (95 %CI: -1.45 - -0.43, P< 0.01, I2= 93.4 %), and for anxiety symptoms, the mean effect was -1.33 (95 %CI: -2.10 - -0.56, P< 0.01, I2= 92.3 %). The mean effect was -0.51 (95 %CI: -0.67 - -0.35, P< 0.01, I2= 36.7 %) for older adults without mental disorders, and those with mental disorders the mean effect was ES= -2.15 (95 %CI: -3.01 - - 1.29, P< 0.01, I2= 91.5 %). Conclusion RT was able to improve mental health outcomes in individuals with and without mental disorders, and some RT characteristics influenced the effect of RT on mental health.

Exercise as medicine for depressive symptoms? A systematic review and meta-analysis with meta-regression

OBJECTIVE

To estimate the efficacy of exercise on depressive symptoms compared with non-active control groups and to determine the moderating effects of exercise on depression and the presence of publication bias.

DESIGN

Systematic review and meta-analysis with meta-regression.

DATA SOURCES

The Cochrane Central Register of Controlled Trials, PubMed, MEDLINE, Embase, SPORTDiscus, PsycINFO, Scopus and Web of Science were searched without language restrictions from inception to 13 September2022 (PROSPERO registration no CRD42020210651).

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Randomised controlled trials including participants aged 18 years or older with a diagnosis of major depressive disorder or those with depressive symptoms determined by validated screening measures scoring above the threshold value, investigating the effects of an exercise intervention (aerobic and/or resistance exercise) compared with a non-exercising control group.

RESULTS

Forty-one studies, comprising 2264 participants post intervention were included in the meta-analysis demonstrating large effects (standardised mean difference (SMD)=-0.946, 95% CI -1.18 to -0.71) favouring exercise interventions which corresponds to the number needed to treat (NNT)=2 (95% CI 1.68 to 2.59). Large effects were found in studies with individuals with major depressive disorder (SMD=-0.998, 95% CI -1.39 to -0.61, k=20), supervised exercise interventions (SMD=-1.026, 95% CI -1.28 to -0.77, k=40) and moderate effects when analyses were restricted to low risk of bias studies (SMD=-0.666, 95% CI -0.99 to -0.34, k=12, NNT=2.8 (95% CI 1.94 to 5.22)).

CONCLUSION

Exercise is efficacious in treating depression and depressive symptoms and should be offered as an evidence-based treatment option focusing on supervised and group exercise with moderate intensity and aerobic exercise regimes. The small sample sizes of many trials and high heterogeneity in methods should be considered when interpreting the results.

Effect of Online Home-Based Resistance Exercise Training on Physical Fitness, Depression, Stress, and Well-Being in Middle-Aged Persons: A Pilot Study

This study investigated the effect of online home-based resistance exercise training on fitness, depression, stress, and well-being. A total of 67 individuals participated. Of them, 28 participants (13 men and 15 women, average age: 45.1 ± 12.2 years) performed the same exercise training online (n = 17), using Zoom, or in person (n = 11) in 2020 (Study 1). In addition, 39 participants (15 men and 24 women; average age: 47.6 ± 10.8 years) performed eight weeks of online home-based resistance exercise training in 2021 (Study 2). The participants performed low-load resistance exercises twice a week for eight weeks (16 sessions). Muscle strength, thigh muscle cross-sectional area, fitness parameters, blood pressure, mental health (Center for Epidemiologic Studies-Depression Scale-CES-D; and Kessler Psychological Distress scale-K6), and well-being (Well-Being Index-WHO-5) were measured pre-and post-resistance training. In Study 1, eight weeks of online home-based resistance training improved CES-D (p = 0.003), and a similar tendency was observed in resistance training (RT) with the in-person group (p = 0.06). There was a significant improvement in CES-D symptoms after the online home-based resistance training in Study 2 (p = 0.009). However, there were no significant changes in the WHO-5 and K6. Our results suggest that online low-load resistance training improves fitness parameters and curbs depressive status.

Social Support Initiatives That Facilitate Exercise Participation in Community Gyms for People with Disability: A Scoping Review

People with disability report social support facilitates participation in physical activity. A scoping review explored social support strategies used to facilitate exercise participation for people with disability (aged ≥ 15 years) in community gym settings. Seven electronic databases were searched. Studies were screened for eligibility based on title and abstract followed by full-text review. Data were analysed using content analysis and narrative synthesis. Forty-two articles reporting data from 35 studies were included. Eight types of social support were identified: supervision (n = 30), peer support (n = 21), specialist support (n = 19), orientation (n = 15), education (n = 7), logistical support (n = 6), motivational support (n = 5) and organised social activities (n = 4). Direct supervision was typically provided 1:1 or in small groups by staff experienced working with people with disability. Peer support typically involved support from exercise group participants or a peer mentor. Specialist support was usually provided by a health or exercise professional either directly to people with disability or to the people providing support to them (e.g., trainer). Orientation to the gym environment, equipment and exercise program was usually provided over 1 or 2 sessions. Gym staff may use these strategies to guide the implementation of social supports within their facilities to promote social connectedness and participation for people with disability.

Treatment effect of exercise training on post-stroke depression in middle-aged and older adults: A meta-analysis

OBJECTIVE

This meta-analytic study examined the effects of exercise training on depressive symptoms in mild stroke patients and the moderating effects of exercise type, therapeutic method, culture, sex, and gross domestic product (GDP) in the patient's country.

METHODS

The Metafor package in R was chosen to conduct the meta-analysis, and the quality of each empirical study was evaluated according to the grading system in Cochrane. We included 36 empirical studies and 1477 patients.

RESULTS

The results showed that the treatment effect of exercise training on depression in mild stroke patients was significant. The moderating effects of culture and therapeutic method were significant, but not for exercise type, sex, or GDP in the patient's country. The moderating effect of culture can be explained by the therapeutic method in different cultures.

CONCLUSION

Fitness exercise is an effective method for improving depressive symptoms in mild stroke patients. Its effectiveness is moderated by the therapeutic method but is not affected by demographics, exercise type, gender, or GDP level.

A Narrative Review on the Non-Pharmacologic Interventions in Post-Stroke Depression

Stroke is a major cause of death and disability globally. Post-stroke depression (PSD) is a major driver for poor recovery and poor quality of life with extra burden for the patient and the caregiver. We have previously shown the inflammatory basis of PSD with associated bioenergetic failure, disruption of the blood-brain barrier, cell death, and persistent maladapted inflammation, making the PSD a norm rather than the exception, highlighting the unmet need for therapeutic intervention in PSD across the recovery trajectory. In this era, various interventions are focused on pharmacotherapy; however, non-pill-based medication should also be explored as post-stroke patients are likely to suffer from the adverse effects of polypharmacy. This narrated review explores the status of non-pharmacological interventions in managing PSD. We performed a PubMed search using pre-specified keywords looking at various non-pharmacologic approaches for the management of PSD. Worldwide, approaches such as non-invasive brain stimulation, behavioral and psychosocial therapy, as well as exercise, acupuncture, music, literature, and art therapies are available as monotherapy or adjunctive treatment for PSD. While current literature shows convincing results on the benefits of non-pharmacologic interventions, more robust studies are necessary to determine its utility in PSD.

Characterization of muscle strength using the strength domain of the stroke impact scale: An integrative review

BACKGROUND AND OBJECTIVE: Muscle weakness is among the most common and obvious impairments in older adults and individuals with neurologic disorders. Although impairments in muscle strength are typically characterized using performance measures, the impairments have also been described using patient or observer-report. The objective of this review was to summarize literature describing use of a patient-report instrument, the Strength Domain (SD) of the Stroke Impact Scale (SIS), to grade strength impairments. METHODS: Peer-reviewed literature reporting SD scores for the SIS was identified using computerized searches of the CINAHL, PubMed, and Scopus databases followed by hand searches. Potentially relevant articles were then mined for data on the participants tested, the SIS version used, scores documented, and clinimetric properties reported. RESULTS: Sixty-five articles were judged appropriate based on inclusion and exclusion criteria. The articles involved more than 7000 residents of 22 countries. All articles focused on individuals with stroke (usually chronic), although one also included community-dwelling adults without stroke. The SIS version used was frequently unreported, but 3.0 was version most often specified. For articles reporting SD scale scores the mean ranged from 19.7 to 85.5. Construct (known groups, convergent, and discriminant) validity of the SD was supported by the literature as was its internal consistency and test-retest reliability. Responsiveness of the SD was evinced by numerous studies showing increases in SD scores with time or accompanying effective interventions. However, only one study indicated responsiveness using an anchor-based statistic. CONCLUSIONS: The SD of the SIS is a well-established and mostly clinimetrically sound patient-report measure of paretic limb strength among individuals with stroke. Its use with individuals with weakness accompanying aging or diagnoses other than stroke remains to be substantiated.

Effect of Exercise Interventions on Health-Related Quality of Life After Stroke and Transient Ischemic Attack: A Systematic Review and Meta-Analysis

Exercise interventions have been shown to help physical fitness, walking, and balance after stroke, but data are lacking on whether such interventions lead to improvements in health-related quality of life (HRQoL). In this systematic review and meta-analysis, 30 randomized controlled trials (n=1836 patients) were found from PubMed, OVID MEDLINE, Web of Science, CINAHL, SCOPUS, The Cochrane Library, and TRIP databases when searched from 1966 to February 2020 that examine the effects of exercise interventions on HRQoL after stroke or transient ischemic attack. Exercise interventions resulted in small to moderate beneficial effects on HRQoL at intervention end (standardized mean difference, -0.23 [95% CI, -0.40 to -0.07]) that appeared to diminish at longer-term follow-up (standardized mean difference, -0.11 [95% CI, -0.26 to 0.04]). Exercise was associated with moderate improvements in physical health (standardized mean difference, -0.33 [95% CI, -0.61 to -0.04]) and mental health (standardized mean difference, -0.29 [95% CI, -0.49 to -0.09]) domains of HRQoL while effects on social or cognitive composites showed little difference. Interventions that were initiated within 6 months, lasted at least 12 weeks in duration, involved at least 150 minutes per week, and included resistance training appeared most effective. Exercise can lead to moderate beneficial effects on HRQoL and should be considered an integral part of stroke rehabilitation.

Strengthening the Case for Cluster Set Resistance Training in Aged and Clinical Settings: Emerging Evidence, Proposed Benefits and Suggestions

Resistance training (RT) is a fundamental component of exercise prescription aimed at improving overall health and function. RT techniques such as cluster set (CS) configurations, characterized by additional short intra-set or inter-repetition rest intervals, have been shown to maintain acute muscular force, velocity, and 'power' outputs across a RT session, and facilitate positive longer-term neuromuscular adaptations. However, to date CS have mainly been explored from a human performance perspective despite potential for application in health and clinical exercise settings. Therefore, this current opinion piece aims to highlight emerging evidence and provide a rationale for why CS may be an advantageous RT technique for older adults, and across several neurological, neuromuscular, cardiovascular and pulmonary settings. Specifically, CS may minimize acute fatigue and adverse physiologic responses, improve patient tolerance of RT and promote functional adaptations (i.e., force, velocity, and power). Moreover, we propose that CS may be a particularly useful exercise rehabilitation technique where injury or illness, persistent fatigue, weakness and dysfunction exist. We further suggest that CS offer an alternative RT strategy that can be easily implemented alongside existing exercise/rehabilitation programs requiring no extra cost, minimal upskilling and/or time commitment for the patient and professional. In light of the emerging evidence and likely efficacy in clinical exercise practice, future research should move toward further direct investigation of CS-based RT in a variety of adverse health conditions and across the lifespan given the already demonstrated benefits in healthy populations.

Longer-term health and social care strategies for stroke survivors and their carers: the LoTS2Care research programme including cluster feasibility RCT

Background

It is reported that the longer-term outcomes for stroke survivors are poor, with a range of unmet needs identified.

Objectives

The aims were to develop and test a longer-term stroke care strategy focused on improving the quality of life of stroke survivors and their carers by addressing unmet needs, and maintenance and enhancement of participation (i.e. involvement in life situations).

Design

Five overlapping workstreams were undertaken – (1) refinement of content by semistructured interviews with stroke survivors and their carers and by a review of the literature to inform content and delivery of the care strategy; (2) exploration of service models by national survey and focus groups with purposely selected services; (3) intervention development by interaction with a reference group of stroke survivors, carers, and health and social care professionals; (4) refinement and pilot implementation of the developed intervention in three stroke services (case studies); and (5) a cluster randomised controlled feasibility trial in 10 stroke services across England and Wales.

Setting

The intervention development work and feasibility trial were in stroke services (inclusive of primary, secondary, community and social care provision) across England and Wales.

Participants

Participants were stroke survivors resident in the community and their carers, and health and social care professionals in the included stroke services.

Data sources

Interviews with 28 stroke survivors and their carers at least 9 months post stroke ascertained their needs and the barriers to and facilitators of addressing those needs. Additional literature reviews identified 23 needs. No evidence-based interventions to address these needs were reported; self-management was highlighted as a possible delivery mechanism. In workstream 2, a national survey revealed that the most common model of stroke service provision was care up to 12 months post stroke, reported by 46 (40%) services. Thirty-five (30%) services provided care up to 6 months post stroke and 35 (30%) provided care beyond 12 months, thus identifying 6 months post stroke as an appropriate delivery point for a new intervention. Through focus groups in a range of services, stroke survivors’ perceived unmet needs and the barriers to and enablers of service provision were identified.

Intervention

Using information obtained in workstreams 1 and 2 and working closely with a stakeholder reference group, we developed an intervention based on the unmet needs prioritised by stroke survivors and their carers (workstream 3). In workstream 4, action groups (clinicians, stroke survivors and researchers) were established in three stroke services that led implementation in their service and contributed to the iterative refinement of the intervention, associated training programme and implementation materials. The intervention (called New Start) was delivered at 6 months post stroke. Key components were problem-solving self-management with survivors and carers, help with obtaining usable information, and helping survivors and their carers build sustainable, flexible support networks.

Results

A cluster randomised feasibility trial (workstream 5) was successfully implemented in 10 stroke services across England and Wales, with associated process and health economic evaluations. Five services were randomised to provide New Start, while five continued with usual care; 269 participants were recruited. Progression criteria – in terms of our pre-determined (red, amber, green) criteria for progress to a full trial: target stroke survivor recruitment rates were achieved, on average, across sites (24.1 per site over 6 months, green); 216 (80.3%) registered stroke survivors returned follow-up questionnaires at 9 months (84.1% in the intervention arm and 75.8% in the usual care arm, green); according to data reported by sites, overall, 95.2% of registered stroke survivors were offered at least one session of the intervention (green); all five intervention sites had at least two facilitators deemed competent, delivered the New Start intervention and provided it to stroke survivors (green). However, at some sites, there were concerns regarding the number of stroke survivors being offered, accepting and receiving the intervention. Only small differences in outcomes and costs were observed between the New Start and usual care groups, and considerable uncertainty around the cost-effectiveness remains.

Conclusions

We report a complex programme of work that has described the longer-term needs of stroke survivors and highlighted evidence and service gaps. Working closely with stroke survivors, an intervention was developed that has been refined in three services and feasibility tested in a cluster randomised controlled trial. Further refinement of the target population and optimisation of the intervention materials is required prior to a full randomised controlled trial evaluation.

Future work

Optimisation of the intervention, and clearer specification of recipients, are required prior to a full trial evaluation.

The Effects of Exclusively Resistance Training-Based Supervised Programs in People with Depression: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

The purpose of this study was to systematically review the effects of supervised resistance training (RT) programs in people diagnosed with depression or depressive symptoms. The following databases were used to search and retrieve the articles: Cochrane Library, EBSCO, PEDro, PubMed, Scopus and Web of Science. The search was conducted in late June 2020. Search protocol required the title to contain the words depression or depressive or dysthymia. Furthermore, the title, abstract or keywords had to contain the words or expressions: "randomized controlled trial"; and "strength training" or "resistance training" or "resisted training" or "weight training". The screening provided 136 results. After the removal of duplicates, 70 records remained. Further screening of titles and abstracts resulted in the elimination of 57 papers. Therefore, 13 records were eligible for further scrutiny. Of the 13 records, nine were excluded, and the final sample consisted of four articles. Results were highly heterogeneous, with half of the studies showing positive effects of resistance training and half showing no effects. In two of the four combinations, the meta-analysis revealed significant benefits of RT in improving depressive symptoms (p ≤ 0.05). However, considering significant differences with moderate (Effect Size = 0.62) and small (ES = 0.53) effects, the heterogeneity was above 50%, thus suggesting a substantial level. To draw meaningful conclusions, future well-designed randomized controlled trials (RCTs) are needed that focus on understudied RT as a treatment for depression.

Resistance training in stroke rehabilitation: systematic review and meta-analysis

Objective:

This systematic review and meta-analysis investigates the effects of resistance training in supporting the recovery in stroke patients.

Data sources:

PubMed, the Cochrane Central Register of Controlled Trials and the PEDro databases were reviewed up to 30 April 2020.

Review methods:

Randomized controlled trials were included, who compared: (i) resistance training with no intervention, (ii) resistance training with other interventions and (iii) different resistance training protocols in stroke rehabilitation.

Results:

Overall 30 trials ( n = 1051) were enrolled. The parameters evaluated were: (1) gait, (2) muscular force and motor function, (3) mobility, balance and postural control, (4) health related quality of life, independence and reintegration, (5) spasticity and hypertonia, (6) cardiorespiratory fitness, (7) cognitive abilities and emotional state and (8) other health-relevant physiological indicators. The data indicates that: (i) resistance training is beneficial for the majority of parameters observed, (ii) resistance training is superior to other therapies on muscular force and motor function of lower and upper limbs, health related quality of life, independence and reintegration and other health-relevant physiological indicators, not significantly different from other therapies on walking ability, mobility balance and postural control and spasticity and hypertonia, and inferior to ergometer training on cardiorespiratory fitness and (iii) the type of resistance training protocol significantly impacts its effect; leg press is more efficient than knee extension and high intensity training is superior than low intensity training.

Conclusion:

Current data indicates that resistance training may be beneficial in supporting the recovery of stroke patients. However, the current evidence is insufficient for evidence-based rehabilitation.

Physical fitness training for stroke patients

BACKGROUND

Levels of physical activity and physical fitness are low after stroke. Interventions to increase physical fitness could reduce mortality and reduce disability through increased function.

OBJECTIVES

The primary objectives of this updated review were to determine whether fitness training after stroke reduces death, death or dependence, and disability. The secondary objectives were to determine the effects of training on adverse events, risk factors, physical fitness, mobility, physical function, health status and quality of life, mood, and cognitive function.

SEARCH METHODS

In July 2018 we searched the Cochrane Stroke Trials Register, CENTRAL, MEDLINE, Embase, CINAHL, SPORTDiscus, PsycINFO, and four additional databases. We also searched ongoing trials registers and conference proceedings, screened reference lists, and contacted experts in the field.

SELECTION CRITERIA

Randomised trials comparing either cardiorespiratory training or resistance training, or both (mixed training), with usual care, no intervention, or a non-exercise intervention in stroke survivors.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies, assessed quality and risk of bias, and extracted data. We analysed data using random-effects meta-analyses and assessed the quality of the evidence using the GRADE approach. Diverse outcome measures limited the intended analyses.

MAIN RESULTS

We included 75 studies, involving 3017 mostly ambulatory participants, which comprised cardiorespiratory (32 studies, 1631 participants), resistance (20 studies, 779 participants), and mixed training interventions (23 studies, 1207 participants). Death was not influenced by any intervention; risk differences were all 0.00 (low-certainty evidence). There were few deaths overall (19/3017 at end of intervention and 19/1469 at end of follow-up). None of the studies assessed death or dependence as a composite outcome. Disability scores were improved at end of intervention by cardiorespiratory training (standardised mean difference (SMD) 0.52, 95% CI 0.19 to 0.84; 8 studies, 462 participants; P = 0.002; moderate-certainty evidence) and mixed training (SMD 0.23, 95% CI 0.03 to 0.42; 9 studies, 604 participants; P = 0.02; low-certainty evidence). There were too few data to assess the effects of resistance training on disability. Secondary outcomes showed multiple benefits for physical fitness (VO2 peak and strength), mobility (walking speed) and physical function (balance). These physical effects tended to be intervention-specific with the evidence mostly low or moderate certainty. Risk factor data were limited or showed no effects apart from cardiorespiratory fitness (VO2 peak), which increased after cardiorespiratory training (mean difference (MD) 3.40 mL/kg/min, 95% CI 2.98 to 3.83; 9 studies, 438 participants; moderate-certainty evidence). There was no evidence of any serious adverse events. Lack of data prevents conclusions about effects of training on mood, quality of life, and cognition. Lack of data also meant benefits at follow-up (i.e. after training had stopped) were unclear but some mobility benefits did persist. Risk of bias varied across studies but imbalanced amounts of exposure in control and intervention groups was a common issue affecting many comparisons.

AUTHORS' CONCLUSIONS

Few deaths overall suggest exercise is a safe intervention but means we cannot determine whether exercise reduces mortality or the chance of death or dependency. Cardiorespiratory training and, to a lesser extent mixed training, reduce disability during or after usual stroke care; this could be mediated by improved mobility and balance. There is sufficient evidence to incorporate cardiorespiratory and mixed training, involving walking, within post-stroke rehabilitation programmes to improve fitness, balance and the speed and capacity of walking. The magnitude of VO2 peak increase after cardiorespiratory training has been suggested to reduce risk of stroke hospitalisation by ˜7%. Cognitive function is under-investigated despite being a key outcome of interest for patients. Further well-designed randomised trials are needed to determine the optimal exercise prescription, the range of benefits and any long-term benefits.

Comparative effectiveness of three exercise types to treat clinical depression in older adults: A systematic review and network meta-analysis of randomised controlled trials

BACKGROUND

Few studies have directly compared the effects of different exercise therapies on clinical depression in older adults. Thus, we conducted a systematic review and network meta-analysis of current evidence from randomised controlled trials (RCTs) to compare the effectiveness of three major exercise types (aerobic, resistance, and mind-body exercise) in clinically depressed older adults.

METHODS

We followed PRISMA-NMA guidelines and searched databases for eligible RCTs (inception - September 12^th, 2019). RCTs were eligible if they included clinically depressed adults aged >65 years, implemented one or more exercise therapy arms using aerobic, resistance, or mind-body exercise, and assessed depressive symptoms at baseline and follow-up using a validated clinical questionnaire.

RESULTS

A network meta-analysis was performed on 15 eligible RCTs comprising 596 participants (321 treatment and 275 controls), including aerobic (n = 6), resistance (n = 5), and mind-body (n = 4) exercise trials. Compared with controls, mind-body exercise showed the largest improvement on depressive symptoms (g = -0.87 to -1.38), followed by aerobic exercise (g = -0.51 to -1.02), and resistance exercise (g = -0.41 to -0.92). Notably, there were no statistically significant differences between exercise types: aerobic versus resistance (g = -0.10, PrI = -2.23, 2.03), mind-body versus aerobic (g = -0.36, PrI = -2.69, 1.97), or mind-body versus resistance (g = -0.46, PrI = -2.75, 1.83).

CONCLUSIONS

These findings should guide optimal exercise prescription for allied health professionals and stakeholders in clinical geriatrics. Notably, clinically depressed older adults may be encouraged to self-select their preferred exercise type in order to achieve therapeutic benefit on symptoms of depression. In coalition with high levels of compliance, these data provide encouraging evidence for the antidepressant effect of either aerobic, resistance, or mind-body exercise as effective treatment adjucts for older adults presenting with clinical depression.

Exercise and Depressive Disorder

Depression is a psychiatric disorder characterized by low mood, loss of interest/enjoyment, and reduced energy and one of the five leading causes of disability and a major contributor to all-cause mortality worldwide. People with depression have, between others, a reduced life expectancy, worse quality of life and cardiorespiratory fitness, and increased risk of type 2 diabetes, compared to the general population. Furthermore, the economic burden of mental disorders including depression is evident, and it is expected to increase to more than double by 2030. Therefore, reducing the growing burden of mental disorders such as depression should be a health priority. Improved prevention and treatment are two key factors that may reduce the burden of depression. Pharmacological- and psychotherapy-based interventions have been traditionally considered for treating depression disorders; however, there is an increasing amount of scientific evidence confirming that physical activity and physical exercise should be highly considered in prevention and treatment of depressive disorders. In this chapter, we aim to summarize and discuss the research progress of physical activity and exercise in prevention and treatment of depressive disorder. Specifically, we summarized and discussed the research progress of the prognostic use of physical activity for incident depression, the importance of sedentary behavior and other outcomes typically improved by physical activity/exercise such as cardiorespiratory fitness for future depression, the research progress of the evidence of the benefits of exercise in people with depression disorders, the resistance training effects in adults and older adults with depression, and the recommendations for the prescription of exercise for people with depression.

Tai Chi Combined With Resistance Training for Adults Aged 50 Years and Older: A Systematic Review

BACKGROUND AND PURPOSE

Despite Tai Chi and resistance training being recommended as suitable exercise for older adults, there are no systematic reviews synthesizing the effectiveness of a combination of Tai Chi and resistance training on health promotion of older adults. This study aimed to review the existing literature regarding the effect of Tai Chi and resistance training on physical health, mental health, pain, health-related quality of life, and age-related impairment in adults aged 50 years and older.

METHODS

A systematic review was conducted to report the health outcomes of Tai Chi combined with resistance training research in adults aged 50 years and older. Articles were identified by searching PubMed, Scopus, Web of Science, CINAHL, MEDLINE, Physiotherapy Evidence Database (PEDro), and the Cochrane library using search terms representing "Tai Chi" and "resistance" and "older adults." Quantitative experimental studies with participants aged 50 years and older, where one of the interventions was Tai Chi and resistance training, were included.

RESULTS AND DISCUSSION

The literature search yielded 648 articles from which 7 met the inclusion criteria. Collectively, the studies involved 703 participants aged 50 years and older, including healthy older adults, older adults with history of falls, postmenopausal women, and people diagnosed with end-stage hip osteoarthritis. Studies included different Tai Chi forms in combination with various types of resistance training. Training sessions were 2 to 7.5 h/wk and lasted between 12 weeks and 12 months. After long-term Tai Chi and resistance training, the participants showed significant improvement in upper and lower extremity muscle strength, aerobic endurance, balance, and mobility. However, 1 study failed to show improvement in Functional Movement Screening compared with traditional Tai Chi and nonexercise groups. No study examined the effects of Tai Chi and resistance training on health-related quality of life, fear of falling, or mental health in adults aged 50 years and older.

CONCLUSIONS

The review supports that Tai Chi in combination with resistance training improves physical function and muscle strength in adults aged 50 years and older.

[Physical activity as therapeutic intervention for depression]

AIM

This article gives a conspectus of the present state of research on the efficiency of exercise as a treatment for patients suffering from depression.

METHODS

A systematic review of articles published between December 1980 and March 2016 was carried out. The review focused on studies that examined the effects of exercise compared to control conditions in the treatment of depression. Extracted and analyzed information from the articles included details about participants, characteristics of exercise and control conditions, assessments, study design and outcomes.

RESULTS

A total of 34 of the 48 studies included in the literature search reported a significant reduction of depressive symptoms due to exercise interventions. There was a trend to reduced depressive symptoms following the exercise interventions in five studies. In nine studies no positive impact of exercise on depression and affective well-being could be detected.

DISCUSSION

This review article shows that physical activity decreases depressive symptoms and increases affective well-being in patients with depressive diseases; therefore, exercise should be recommended as a component of depression treatment within the framework of a multi-dimensional approach.

Physical fitness interventions for nonambulatory stroke survivors: A mixed-methods systematic review and meta-analysis

INTRODUCTION

Physical fitness training after stroke is recommended in guidelines across the world, but evidence pertains mainly to ambulatory stroke survivors. Nonambulatory stroke survivors (FAC score ≤2) are at increased risk of recurrent stroke due to limited physical activity. This systematic review aimed to synthesize evidence regarding case fatality, effects, experiences, and feasibility of fitness training for nonambulatory stroke survivors.

METHODS

Eight major databases were searched for any type of study design. Two independent reviewers selected studies, extracted data, and assessed study quality, using published tools. Random-effects meta-analysis was used. Following their separate analysis, qualitative and quantitative data were synthesized using a published framework.

RESULTS

Of 13,614 records, 33 studies involving 910 nonambulatory participants met inclusion criteria. Most studies were of moderate quality. Interventions comprised assisted walking (25 studies), cycle ergometer training (5 studies), and other training (3 studies), mainly in acute settings. Case fatality did not differ between intervention (1.75%) and control (0.88%) groups (95% CI 0.13-3.78, p = 0.67). Compared with control interventions, assisted walking significantly improved: fat mass, peak heart rate, peak oxygen uptake and walking endurance, maximum walking speed, and mobility at intervention end, and walking endurance, balance, mobility, and independent walking at follow-up. Cycle ergometry significantly improved peak heart rate, work load, peak ventilation, peak carbon dioxide production, HDL cholesterol, fasting insulin and fasting glucose, and independence at intervention end. Effectiveness of other training could not be established. There were insufficient qualitative data to draw conclusions about participants' experiences, but those reported were positive. There were few intervention-related adverse events, and dropout rate ranged from 12 to 20%.

CONCLUSIONS

Findings suggest safety, effectiveness, and feasibility of adapted fitness training for screened nonambulatory stroke survivors. Further research needs to investigate the clinical and cost-effectiveness as well as experiences of fitness training-especially for chronic stroke survivors in community settings.

Association of Efficacy of Resistance Exercise Training With Depressive Symptoms: Meta-analysis and Meta-regression Analysis of Randomized Clinical Trials

IMPORTANCE

The physical benefits of resistance exercise training (RET) are well documented, but less is known regarding the association of RET with mental health outcomes. To date, no quantitative synthesis of the antidepressant effects of RET has been conducted.

OBJECTIVES

To estimate the association of efficacy of RET with depressive symptoms and determine the extent to which logical, theoretical, and/or prior empirical variables are associated with depressive symptoms and whether the association of efficacy of RET with depressive symptoms accounts for variability in the overall effect size.

DATA SOURCES

Articles published before August 2017, located using Google Scholar, MEDLINE, PsycINFO, PubMed, and Web of Science.

STUDY SELECTION

Randomized clinical trials included randomization to RET (n = 947) or a nonactive control condition (n = 930).

DATA EXTRACTION AND SYNTHESIS

Hedges d effect sizes were computed and random-effects models were used for all analyses. Meta-regression was conducted to quantify the potential moderating influence of participant and trial characteristics.

MAIN OUTCOMES AND MEASURES

Randomized clinical trials used validated measures of depressive symptoms assessed at baseline and midintervention and/or postintervention. Four primary moderators were selected a priori to provide focused research hypotheses about variation in effect size: total volume of prescribed RET, whether participants were healthy or physically or mentally ill, whether or not allocation and/or assessment were blinded, and whether or not the RET intervention resulted in a significant improvement in strength.

RESULTS

Fifty-four effects were derived from 33 randomized clinical trials involving 1877 participants. Resistance exercise training was associated with a significant reduction in depressive symptoms with a moderate-sized mean effect ∆ of 0.66 (95% CI, 0.48-0.83; z = 7.35; P < .001). Significant heterogeneity was indicated (total Q = 216.92, df = 53; P < .001; I2 = 76.0% [95% CI, 72.7%-79.0%]), and sampling error accounted for 32.9% of observed variance. The number needed to treat was 4. Total volume of prescribed RET, participant health status, and strength improvements were not significantly associated with the antidepressant effect of RET. However, smaller reductions in depressive symptoms were derived from randomized clinical trials with blinded allocation and/or assessment.

CONCLUSIONS AND RELEVANCE

Resistance exercise training significantly reduced depressive symptoms among adults regardless of health status, total prescribed volume of RET, or significant improvements in strength. Better-quality randomized clinical trials blinding both allocation and assessment and comparing RET with other empirically supported treatments for depressive symptoms are needed.

A survey of exercise professionals' barriers and facilitators to working with stroke survivors

Stroke survivors (SSs) are largely inactive despite the benefits of exercise. Exercise professionals (EPs), skilled in exercise prescription and motivation, may have a role in promoting exercise among SSs. However, the number of EPs working with SSs is estimated to be low. This study aimed to investigate EPs' opinions on working with SSs by rating their agreement of barriers and facilitators to working with SSs. The study also investigated EPs skills, interest and experience working with SSs and the relationship between EPs' barriers and facilitators with their training on stroke. A descriptive cross-sectional study was conducted using a researcher-designed online survey between October and December 2015. Purposive sampling was used to survey EPs on the Register of Exercise Professionals in Ireland (n = 277). The response rate was 31% (87/277). Only 22% (19/86) of EPs had experience working with SSs. The primary barriers rated by EPs included insufficient training on psychological problems post-stroke (84%; 61/73), unsuitable equipment for SSs (69%; 50/73) and the level of supervision SSs require (56%; 41/73). The primary facilitators rated included access to suitable equipment (97%; 69/71), practical (100%; 71/71) and theoretical training (93%; 66/71) on stroke. Respondents with no training on stroke were significantly more likely to agree that insufficient training on psychological problems post-stroke and lack of experience were barriers. Seventy-six per cent of EPs (58/76) were interested in one-to-one exercise sessions with SSs but only 53% (40/76) were interested in group sessions. Eighty-two per cent of EPs (62/76) rated their motivational skills as good or very good but 42% (32/76) indicated having only acceptable skills dealing with psychological problems. Results indicate that EPs are interested in working with SSs despite limited experience and practical barriers. Training opportunities on stroke need to be developed; taking into account EPs' barriers, facilitators and skills along with access to suitable equipment.

Effect of exercise augmentation of cognitive behavioural therapy for the treatment of suicidal ideation and depression

BACKGROUND

Suicidal ideation and depression are prevalent and costly conditions that reduce quality of life. This study was designed to determine the efficacy of exercise as an adjunct to cognitive behavioural therapy (CBT) for suicidal ideation and depression among depressed individuals.

METHODS

In a randomized clinical trial, 54 mildly to moderately depressed patients (54% female, mean age=48.25) were assigned to a combined CBT and exercise group or to a CBT only group. Both groups received one weekly session of therapy for 12 weeks, while the combined group also completed exercise three times weekly over the same period. Self-reported suicidal ideation, depression, and activities of daily living were measured at the beginning and the end of treatment.

RESULTS

Multilevel modelling revealed greater improvements in suicidal ideation, depression, and activities of daily living in the combined CBT and exercise group, compared to the CBT only group.

LIMITATIONS

No follow-up data were collected, so the long-term effects (i.e., maintenance of gains) is unclear.

CONCLUSIONS

The findings revealed that exercise adjunct to CBT effectively decreases both depressive symptoms and suicidal ideation in mildly to moderately depressed individuals.

Challenges Establishing the Efficacy of Exercise as an Antidepressant Treatment: A Systematic Review and Meta-Analysis of Control Group Responses in Exercise Randomised Controlled Trials

BACKGROUND

Whilst previous meta-analyses have demonstrated that control group responses (CGRs) can negatively influence antidepressant efficacy, no such meta-analysis exists in exercise randomised controlled trials (RCTs).

OBJECTIVE

The aim of this study was to conduct a systematic review and meta-analysis investigating CGRs and predictors in control groups of exercise RCTs among adults with depression.

METHODS

Three authors acquired RCTs from a previous Cochrane review (2013) and conducted updated searches of major databases from January 2013 to August 2015. We included exercise RCTs that (1) involved adults with major depressive disorder (MDD) or depressive symptoms; (2) measured depressive symptoms pre- and post-intervention using a validated measure [e.g. Hamilton Depression Scale (HAM-D)]; and (3) included a non-active control group. A random effects meta-analysis calculating the standardised mean difference (SMD) together with 95 % confidence intervals (CIs) was employed to determine CGR.

RESULTS

Across 41 studies, 1122 adults with depression were included [mean (SD) age 50 (18) years, 63 % female]. A large CGR of improved depressive symptoms was evident across all studies (SMD -0.920, 95 % CI -1.11 to -0.729). CGRs were elevated across all subgroup analyses, including high quality studies (n = 11, SMD -1.430, 95 % CI -1.771 to -1.090) and MDD participants (n = 18, SMD -1.248, 95 % CI = -1.585 to -0.911). The CGR equated to an improvement of -7.5 points on the HAM-D (95 % CI -10.30 to -4.89). In MDD participants, increasing age moderated a smaller CGR, while the percentage of drop-outs, baseline depressive symptoms and a longer control group duration moderated a larger CGR (i.e. improvement) (p < 0.05).

CONCLUSION

In order to demonstrate effectiveness, exercise has to overcome a powerful CGR of approximately double that reported for antidepressant RCTS.

Physical Activity and the Risk of Depression in Community-Dwelling Korean Adults With a History of Stroke

BACKGROUND

Physical activity (PA) is believed to improve mental health, including depression. However, whether recommended PA levels have a similar impact in individuals with poststroke depression is unclear.

OBJECTIVE

The aim of this study was to apply a quasi-experimental propensity score (PS) matching control for covariate differences and compare the effects of PA on reducing depression risk among people with stroke.

DESIGN

A cross-sectional design was used for this study.

METHODS

Health-related information for community-dwelling adults (N=4,555) who reported having had a stroke was extracted from the 2013 Korean Community Health Survey data set. The survey participants were asked a series of questions about depression, recommended PA levels (moderate and vigorous intensity), and chronic conditions. A multivariable regression model, inverse probability weighting adjustment, and Greedy algorithms with 1:1 matching and covariate adjustment were used to estimate the effects of PA on risk of depression. The dependent variable was diagnosis of depression, and the primary independent variable was PA. Baseline covariates were 10 demographic and 9 chronic condition variables.

RESULTS

Without PS methods, there were significant differences in baseline covariates (16 out of 19) between people who performed PA and those who did not perform PA. After applying 1:1 matching, the number of patients in each group comparing the effect of PA numbered 1,970, and 13 covariates did not differ significantly between the 2 groups. Physical activity reduced the risk of poststroke depression by 36.1% to 42.4% (odds ratio=0.639-0.376) across the 3 methods.

LIMITATIONS

Unaccounted-for covariates, including stroke severity, predepression status, and history of depression treatments, may have biased the results.

CONCLUSIONS

The findings suggest that recommended PA levels have protective relationships with the risk of poststroke depression.

Characterising community exercise programmes delivered by fitness instructors for people with neurological conditions: a scoping review

A scoping review was conducted to characterise evaluations of community-based exercise programmes (CBEPs) delivered by fitness instructors to people with neurological conditions. Literature published from 1946 to April 2014 in MEDLINE, EMBASE, CINAHL, Cochrane Database of Systematic Reviews and the grey literature were searched. Search terms included community, programme, exercise, adult, brain disease and spinal cord disease. Two reviewers independently screened titles and abstracts for inclusion. One author reviewed full-text articles to evaluate eligibility. Studies were included if the study objective was to evaluate an exercise programme, the programme was community-based and delivered by fitness instructors, exercise participants were ≥18 years of age and had a neurological condition, and a full-text article was available and written in English. After reviewing 1785 titles and abstracts, 18 (1.01%) articles describing 15 studies were included in the review. One author completed data abstraction from the included studies. A second reviewer independently verified the extracted data for accuracy. Exercise programmes most commonly included people with stroke (47%) and Parkinson's disease (40%), incorporated a stand-alone (80%), multi-component (20%), group (67%), individual (20%) and combined format (13%), strength training (40%) and functional/task-oriented training (40%), reported a minimum walking requirement (67%), and involved a healthcare professional (HCP) with various roles (53%), including training (27%), advising and supporting (33%). The most commonly examined participant outcomes were health-related quality of life (60%) and functional balance (47%). More research is needed to develop CBEPs targeting individuals with low ambulatory function and multiple neurological conditions, to develop recommendations for the involvement of HCPs in CBEPs and document their involvement, and to evaluate system-level outcomes such as cost, healthcare utilisation and impact on caregivers. The findings support a number of considerations to guide future research into CBEPs delivered by fitness instructors for individuals with neurological conditions.

Exercise as a treatment for depression: A meta-analysis

BACKGROUND

This meta-analysis of randomized controlled trials (RCTs) examines the efficacy of physical exercise as treatment for unipolar depression, both as an independent intervention and as an adjunct intervention to antidepressant medication.

METHODS

We searched PsycINFO, EMBASE, MEDLINE, CENTRAL, and Sports Discus for articles published until November 2014. Effect sizes were computed with random effects models. The main outcome was reduction in depressive symptoms or remission.

RESULTS

A total of 23 RCTs and 977 participants were included. Physical exercise had a moderate to large significant effect on depression compared to control conditions (g=-0.68), but the effect was small and not significant at follow-up (g=-0.22). Exercise compared to no intervention yielded a large and significant effect size (g=-1.24), and exercise had a moderate and significant effect compared to usual care (g=-0.48). The effects of exercise when compared to psychological treatments or antidepressant medication were small and not significant (g=-0.22 and g=-0.08, respectively). Exercise as an adjunct to antidepressant medication yielded a moderate effect (g=-0.50) that trended toward significance.

LIMITATIONS

Use of the arms with the largest clinical effect instead of largest dose may have overestimated the effect of exercise.

CONCLUSIONS

Physical exercise is an effective intervention for depression. It also could be a viable adjunct treatment in combination with antidepressants.

Exercise for depression in older adults: a meta-analysis of randomized controlled trials adjusting for publication bias

OBJECTIVE

To evaluate the antidepressant effects of exercise in older adults, using randomized controlled trial (RCT) data.

METHODS

We conducted a meta-analysis of exercise in older adults, addressing limitations of previous works. RCTs of exercise interventions in older people with depression (≥ 60 years) comparing exercise vs. control were eligible. A random-effects meta-analysis calculating the standardized mean difference (SMD) (95% confidence interval [95%CI]), meta-regressions, and trim, fill, and fail-safe number analyses were conducted.

RESULTS

Eight RCTs were included, representing 138 participants in exercise arms and 129 controls. Exercise had a large and significant effect on depression (SMD = -0.90 [95%CI -0.29 to -1.51]), with a fail-safe number of 71 studies. Significant effects were found for 1) mixed aerobic and anaerobic interventions, 2) at moderate intensity, 3) that were group-based, 4) that utilized mixed supervised and unsupervised formats, and 5) in people without other clinical comorbidities.

CONCLUSION

Adjusting for publication bias increased the beneficial effects of exercise in three subgroup analysis, suggesting that previous meta-analyses have underestimated the benefits of exercise due to publication bias. We advocate that exercise be considered as a routine component of the management of depression in older adults.

Exercise as a treatment for depression: A meta-analysis adjusting for publication bias

The effects of exercise on depression have been a source of contentious debate. Meta-analyses have demonstrated a range of effect sizes. Both inclusion criteria and heterogeneity may influence the effect sizes reported. The extent and influence of publication bias is also unknown. Randomized controlled trials (RCTs) were identified from a recent Cochrane review and searches of major electronic databases from 01/2013 to 08/2015. We included RCTs of exercise interventions in people with depression (including those with a diagnosis of major depressive disorder (MDD) or ratings on depressive symptoms), comparing exercise versus control conditions. A random effects meta-analysis calculating the standardized mean difference (SMD, 95% confidence interval; CI), meta-regressions, trim and fill and fail-safe n analyses were conducted. Twenty-five RCTs were included comparing exercise versus control comparison groups, including 9 examining participants with MDD. Overall, exercise had a large and significant effect on depression (SMD adjusted for publication bias = 1.11 (95% CI 0.79-1.43)) with a fail-safe number of 1057. Most adjusted analyses suggested publication bias led to an underestimated SMD. Larger effects were found for interventions in MDD, utilising aerobic exercise, at moderate and vigorous intensities, in a supervised and unsupervised format. In MDD, larger effects were found for moderate intensity, aerobic exercise, and interventions supervised by exercise professionals. Exercise has a large and significant antidepressant effect in people with depression (including MDD). Previous meta-analyses may have underestimated the benefits of exercise due to publication bias. Our data strongly support the claim that exercise is an evidence-based treatment for depression.

Lower Odds of Poststroke Symptoms of Depression When Physical Activity Guidelines Met: National Health and Nutrition Examination Survey 2011-2012

BACKGROUND

One-third of individuals with stroke report symptoms of depression, which has a negative impact on recovery. Physical activity (PA) is a potentially effective therapy. Our objective was to examine the associations of subjectively assessed PA levels and symptoms of depression in a nationally representative stroke sample.

METHODS

We conducted a cross-sectional study of 175 adults in the National Health and Nutrition Examination Survey 2011-2012 cycle. Moderate, vigorous, and combination equivalent PA metabolic equivalent (MET)-minutes per week averages were derived from the Global Physical Activity Questionnaire, and .the 2008 Physical Activity Guidelines/American College of Sports Medicine recommendations of ≥500 MET-minutes per week of moderate, vigorous, or combination equivalent PA were used as cut points. Depression symptoms were measured using the Patient Health Questionnaire-9.

RESULTS

Meeting moderate PA guidelines resulted in 74% lower odds of having depression symptoms (P < .0001) and 89% lower odds of major symptoms of depression (P = .0003). Meeting vigorous guidelines showed a 91% lower odds of having mild symptoms of depression (P = .04). Participating in some moderate, vigorous, or combination equivalent PA revealed the odds of depression symptoms 13 times greater compared with meeting guidelines (P = .005); odds of mild symptoms of depression were 9 times greater (P = .01); and odds of major symptoms of depression were 15 times greater (P = .006).

CONCLUSIONS

There is a lower risk of developing mild symptoms of depression when vigorous guidelines for PA are met and developing major symptoms of depression when moderate guidelines met. Participating in some PA is not enough to reduce the risk of depression symptoms.

Facilitating Community-Based Exercise for People With Stroke: Cross-Sectional e-Survey of Physical Therapist Practice and Perceived Needs

BACKGROUND

Educating people with stroke about community-based exercise programs (CBEPs) is a recommended practice that physical therapists are well positioned to implement.

OBJECTIVE

The aim of this study was to evaluate the provision of education about CBEPs to people with stroke, barriers to providing education, and preferences for resources to facilitate education among physical therapists in neurological practice.

DESIGN

A cross-sectional e-survey of physical therapists treating adults with stroke in Ontario, Canada, was conducted.

METHODS

A link to the questionnaire was emailed to physical therapists in a provincial stroke network, a provincial physical therapy association, and on hospital and previous research lists.

RESULTS

Responses from 186 physical therapists were analyzed. The percentage of respondents who reported providing CBEP education was 84.4%. Only 36.6% reported typically providing education to ≥7 out of 10 patients with stroke. Physical (90.5%) and preventative (84.6%) health benefits of exercise were most frequently discussed. Therapists reported most commonly delivering education at discharge (73.7%). Most frequently cited barriers to educating patients were a perceived lack of suitable programs (53.2%) and a lack of awareness of local CBEPs (23.8%). Lists of CBEPs (94.1%) or brochures (94.1%) were considered to be facilitators. The percentage of physical therapists providing CBEP education varied across acute, rehabilitation, and public outpatient settings.

LIMITATIONS

The percentage of physical therapists providing education may have been overestimated if respondents who deliver CBEP education were more likely to participate and if participants answered in a socially desirable way.

CONCLUSIONS

Even though a high proportion of physical therapists provide CBEP education, education is not consistently delivered to the majority of patients poststroke. Although a CBEP list or brochure would facilitate education regarding existing CBEPs, efforts to implement CBEPs are needed to help overcome the lack of suitable programs.

Physical fitness training for stroke patients

BACKGROUND

Levels of physical fitness are low after stroke. It is unknown whether improving physical fitness after stroke reduces disability.

OBJECTIVES

To determine whether fitness training after stroke reduces death, dependence, and disability and to assess the effects of training with regard to adverse events, risk factors, physical fitness, mobility, physical function, quality of life, mood, and cognitive function. Interventions to improve cognitive function have attracted increased attention after being identified as the highest rated research priority for life after stroke. Therefore we have added this class of outcomes to this updated review.

SEARCH METHODS

We searched the Cochrane Stroke Group Trials Register (last searched February 2015), the Cochrane Central Register of Controlled Trials (CENTRAL 2015, Issue 1: searched February 2015), MEDLINE (1966 to February 2015), EMBASE (1980 to February 2015), CINAHL (1982 to February 2015), SPORTDiscus (1949 to February 2015), and five additional databases (February 2015). We also searched ongoing trials registers, handsearched relevant journals and conference proceedings, screened reference lists, and contacted experts in the field.

SELECTION CRITERIA

Randomised trials comparing either cardiorespiratory training or resistance training, or both (mixed training), with usual care, no intervention, or a non-exercise intervention in stroke survivors.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials, assessed quality and risk of bias, and extracted data. We analysed data using random-effects meta-analyses. Diverse outcome measures limited the intended analyses.

MAIN RESULTS

We included 58 trials, involving 2797 participants, which comprised cardiorespiratory interventions (28 trials, 1408 participants), resistance interventions (13 trials, 432 participants), and mixed training interventions (17 trials, 957 participants). Thirteen deaths occurred before the end of the intervention and a further nine before the end of follow-up. No dependence data were reported. Diverse outcome measures restricted pooling of data. Global indices of disability show moderate improvement after cardiorespiratory training (standardised mean difference (SMD) 0.52, 95% confidence interval (CI) 0.19 to 0.84; P value = 0.002) and by a small amount after mixed training (SMD 0.26, 95% CI 0.04 to 0.49; P value = 0.02); benefits at follow-up (i.e. after training had stopped) were unclear. There were too few data to assess the effects of resistance training.Cardiorespiratory training involving walking improved maximum walking speed (mean difference (MD) 6.71 metres per minute, 95% CI 2.73 to 10.69), preferred gait speed (MD 4.28 metres per minute, 95% CI 1.71 to 6.84), and walking capacity (MD 30.29 metres in six minutes, 95% CI 16.19 to 44.39) at the end of the intervention. Mixed training, involving walking, increased preferred walking speed (MD 4.54 metres per minute, 95% CI 0.95 to 8.14), and walking capacity (MD 41.60 metres per six minutes, 95% CI 25.25 to 57.95). Balance scores improved slightly after mixed training (SMD 0.27, 95% CI 0.07 to 0.47). Some mobility benefits also persisted at the end of follow-up. The variability, quality of the included trials, and lack of data prevents conclusions about other outcomes and limits generalisability of the observed results.

AUTHORS' CONCLUSIONS

Cardiorespiratory training and, to a lesser extent, mixed training reduce disability during or after usual stroke care; this could be mediated by improved mobility and balance. There is sufficient evidence to incorporate cardiorespiratory and mixed training, involving walking, within post-stroke rehabilitation programmes to improve the speed and tolerance of walking; some improvement in balance could also occur. There is insufficient evidence to support the use of resistance training. The effects of training on death and dependence after stroke are still unclear but these outcomes are rarely observed in physical fitness training trials. Cognitive function is under-investigated despite being a key outcome of interest for patients. Further well-designed randomised trials are needed to determine the optimal exercise prescription and identify long-term benefits.

Body, Person and Environment: Why Promoting Physical Activity (PA) with Stroke Survivors Requires Holistic Thinking

The role of physical activity (PA) after stroke is increasingly recognised as important for function, fitness and wellbeing. Current evidence shows that targeted PA after stroke improves cardiovascular fitness, walking ability and muscle strength and may ameliorate depression and improve quality of life. Secondary stroke prevention and management of cardiovascular risk factors are further health benefits. Despite increasing emphasis on organised exercise classes for stroke, PA levels remain low and effects of organised exercise interventions are not maintained once programmes have finished. Barriers to PA after stroke are complex and innovative approaches to maintaining and promoting long-term engagement in activity are required. This commentary proposes that using the International Classification of Disability and Functioning (ICF) to guide thinking about PA after stroke may help us develop and apply comprehensive solutions that increase PA levels. This approach considers stroke survivors’ PA engagement in terms of Body – the physical impairments imposed by stroke; Person – the role of identity, and psychological factors on PA; and Environment – the physical and social environments that influence PA engagement. The commentary discusses how innovative solutions addressing these issues may enable stroke survivors to be better supported to lead active lifestyles.

Incorporating Pets into Acute Inpatient Rehabilitation: A Case Study

PURPOSE

The use of animals in various healthcare settings dates as far back as the 19th century, and is still a widely practiced intervention even today. The use of animals in the acute rehabilitation setting is a common practice that benefits both the patient's therapy progression and allows the opportunity for financial reimbursement for the facility. As acute rehabilitation facilities continue to cope with ever changing rules and guidelines, the use of alternate modalities can help the facility overcome difficult challenges while focusing on the needs of the patients. The use of animal assisted therapy is illustrated with a stroke patient at an acute rehabilitation facility who benefited from implementing a pet therapy regimen when regular therapy modalities were not helping.

CLINICAL RELEVANCE

Incorporating animal assisted therapy in acute rehabilitation settings is described to obtain greater satisfaction for patients and staff and to facilitate reimbursement for rehabilitation settings.

Dropout from exercise randomized controlled trials among people with depression: A meta-analysis and meta regression

OBJECTIVE

Exercise has established efficacy in improving depressive symptoms. Dropouts from randomized controlled trials (RCT's) pose a threat to the validity of this evidence base, with dropout rates varying across studies. We conducted a systematic review and meta-analysis to investigate the prevalence and predictors of dropout rates among adults with depression participating in exercise RCT's.

METHOD

Three authors identified RCT's from a recent Cochrane review and conducted updated searches of major electronic databases from 01/2013 to 08/2015. We included RCT's of exercise interventions in people with depression (including major depressive disorder (MDD) and depressive symptoms) that reported dropout rates. A random effects meta-analysis and meta regression were conducted.

RESULTS

Overall, 40 RCT's were included reporting dropout rates across 52 exercise interventions including 1720 people with depression (49.1 years (range=19-76 years), 72% female (range=0-100)). The trim and fill adjusted prevalence of dropout across all studies was 18.1% (95%CI=15.0-21.8%) and 17.2% (95%CI=13.5-21.7, N=31) in MDD only. In MDD participants, higher baseline depressive symptoms (β=0.0409, 95%CI=0.0809-0.0009, P=0.04) predicted greater dropout, whilst supervised interventions delivered by physiotherapists (β=-1.2029, 95%CI=-2.0967 to -0.3091, p=0.008) and exercise physiologists (β=-1.3396, 95%CI=-2.4478 to -0.2313, p=0.01) predicted lower dropout. A comparative meta-analysis (N=29) established dropout was lower in exercise than control conditions (OR=0.642, 95%CI=0.43-0.95, p=0.02).

CONCLUSIONS

Exercise is well tolerated by people with depression and drop out in RCT's is lower than control conditions. Thus, exercise is a feasible treatment, in particular when delivered by healthcare professionals with specific training in exercise prescription.

Major Depression as a Predictor of Poor Long-Term Survival in a Brazilian Stroke Cohort (Study of Stroke Mortality and Morbidity in Adults) EMMA study

BACKGROUND

The influence of poststroke depression on long-term survival is poorly investigated. Thus, we aimed to evaluate the influence of major depression disorder (MDD) on long-term survival in the participants from The Study of Stroke Mortality and Morbidity in Adults (EMMA Study) in São Paulo, Brazil.

METHODS

We prospectively evaluated ischemic and hemorrhagic stroke (HS) cases from the EMMA Study. Baseline and stroke characteristics and cardiovascular risk factors were evaluated according to MDD assessed by the Patient Health Questionnaire, which was applied 30 days after index event and periodically during 1-year follow-up. We performed Kaplan-Meier survival analysis, as well as crude and multiple Cox proportional hazards models.

RESULTS

In this subset of the EMMA Study, we evaluated 164 (85.9%) patients with ischemic stroke and 27 (14.1%) with HS. Among these, overall incidence of MDD was 25.1% during 1 year of follow-up, regardless stroke subtype. The peak rate of major depression postacute event was beyond 1 month. We observed a lower survival rate among individuals who developed poststroke MDD than among those who did not develop this condition after 1 year of follow-up (85.4% versus 96.5%, log rank P = .006). After multiple analysis, we kept a higher risk of all-cause mortality among those who developed MDD compared to participants without MDD (hazard ratio = 4.60, 95% confidence interval = 1.36-15.55, P = .01).

CONCLUSION

Our findings suggest that incident MDD is a potential marker of poor prognosis 1 year after stroke.

Effectiveness of interventions for adults with psychological or emotional impairment after stroke: an evidence-based review

This evidence-based review was conducted to evaluate the effectiveness of occupational therapy interventions to prevent or mitigate the effects of psychological or emotional impairments after stroke. Thirty-nine journal articles met the inclusion criteria. Six types of interventions were identified that addressed depression, anxiety, or mental health-related quality of life: exercise or movement based, behavioral therapy and stroke education, behavioral therapy only, stroke education only, care support and coordination, and community-based interventions that included occupational therapy. Evidence from well-conducted research supports using problem-solving or motivational interviewing behavioral techniques to address depression. The evidence is inconclusive for using multicomponent exercise programs to combat depression after stroke and for the use of stroke education and care support and coordination interventions to address poststroke anxiety. One study provided support for an intensive multidisciplinary home program in improving depression, anxiety, and health-related quality of life. The implications of the findings for practice, research, and education are discussed.

Using Exercise to Fight Depression in Older Adults

Abstract. Depression is the most prevalent psychiatric disorder in the general population. Despite a large demand for efficient treatment options, the majority of older depressed adults does not receive adequate treatment: Additional low-threshold treatments are needed for this age group. Over the past two decades, a growing number of randomized controlled trials (RCT) have been conducted, testing the efficacy of physical exercise in the alleviation of depression in older adults. This meta-analysis systematically reviews and evaluates these studies; some subanalyses testing specific effects of different types of exercise and settings are also performed. In order to be included, exercise programs of the RCTs had to fulfill the criteria of exercise according to the American College of Sports Medicine, including a sample mean age of 60 or above and an increased level of depressive symptoms. Eighteen trials with 1,063 participants fulfilled our inclusion criteria. A comparison of the posttreatment depression scores between the exercise and control groups revealed a moderate effect size in favor of the exercise groups (standardized mean difference (SMD) of –0.68, p < .001). The effect was comparable to the results achieved when only the eleven trials with low risk of bias were included (SMD = –0.63, p < .001). The subanalyses showed significant effects for all types of exercise and for supervised interventions. The results of this meta-analysis suggest that physical exercise may serve as a feasible, additional intervention to fight depression in older adults. However, because of small sample sizes of the majority of individual trials and high statistical heterogeneity, results must be interpreted carefully.

Physical fitness exercise versus cognitive behavior therapy on reducing the depressive symptoms among community-dwelling elderly adults: A randomized controlled trial

BACKGROUND

Depression is a major health problem for community-dwelling elderly adults. Since limited resources are available to decrease the high prevalence of depressive symptoms among the elderly adults, improved support for them can be provided if we can determine which intervention is superior in ridding depressive symptoms.

OBJECTIVE

To compare the effectiveness of the physical fitness exercise program and the cognitive behavior therapy program on primary (depressive symptoms) and secondary outcomes (6-min walk distance, quality of life, and social support) for community-dwelling elderly adults with depressive symptoms.

DESIGN AND SETTINGS

A prospective randomized control trial was conducted in three communities in northern Taiwan.

PARTICIPANTS

The elderly adults in the three communities were invited to participate by mail, phone calls, and posters. There were a total of 57 participants who had depressive symptoms and all without impaired cognition that participated in this trial. None of the participants withdrew during the 9 months of follow-up for this study.

METHODS

Fifty-seven participants were randomly assigned to one of the three groups: the physical fitness exercise program group, the cognitive behavior therapy (CBT) group, or the control group. The primary (Geriatric Depression Scale-15, GDS-15), and secondary outcomes (6-min walk distance, SF-36, and Inventory of Socially Supportive Behaviors scales, ISSB) were collected immediately (T2), at 3 months (T3), and at 6 months after the interventions (T4).

RESULTS

After the interventions, the CBT group participants demonstrated significantly lower symptoms of depression (p=0.009) at T2 and perceived more social support from those around them (p<0.001, <0.001 and =0.004, respectively) at three time-point comparisons than the control group. Moreover, after intervention, participants in the physical fitness exercise program group had decreased GDS-15 scores at three time-point comparisons (p=0.003, 0.012 and 0.037, respectively), had a substantially greater 6-min walk distance (p=0.023), a better quality of life (p<0.001), and a better perceived social support at T2 (p<0.001).

CONCLUSIONS

Immediately after a 12-week intervention, there were significant decreases in depressive symptoms and more perceived social support amongst those in the CBT group. When considering the effectiveness in the decrease of depressive symptoms longer term, the increase in the 6-min walk distance and raising the patients' quality of life, physical fitness exercise program may be a better intervention for elderly adults with depressive symptoms.

Classifying physical activity research following stroke using the behavioral epidemiologic framework

BACKGROUND

Stroke is a significant public health issue in the USA and a need emerges to better understand how to reduce an individual's co-morbidity risk. Physical activity is one approach to improving the health of individuals and comprehensive literature supports increased activity as a means to reduce risk of morbidity and mortality. One approach to examining whether research in a field is addressing a public health issue is through application of the behavioral epidemiological framework.

OBJECTIVE

To classify physical activity research for individuals following stroke into distinct phases so that efforts can be made to systematically address gaps and disseminate evidence-based practice.

METHODS

Specific key words were identified and then searched through EBSCO host, PubMed, and Google Scholar. Physical activity and stroke literature from 2000-2014 was categorized into one of five discrete phases. Research in Phase 1 identified associations between activity and health; Phase 2 established valid measures of activity; Phase 3 examined determinants of behavior; Phase 4 evaluated activity interventions; and Phase 5 disseminated evidence-based practice.

RESULTS

A comprehensive review of literature identified 202 articles with 70% categorized in Phase 1 (n = 141), 11% in Phase 2 (n = 23), 10% in Phase 3 (n = 20), 8% in Phase 4 (n = 15), and 1% in Phase 5 (n = 3).

CONCLUSION

Findings suggest that physical activity research for individuals following stroke is in the early stages of development with less than 10% of research evaluating or disseminating interventions.

Exercise for depressive symptoms in stroke patients: a systematic review and meta-analysis

OBJECTIVE

The objective was to conduct a systematic review and meta-analysis of studies that examined the effects of structured exercise on depressive symptoms in stroke patients.

METHODS

We searched for published randomized controlled trials that evaluated the effect of structured exercise programs (e.g. functional, resistance, or aerobic training) on depressive symptoms. The mean effect size, a 95% confidence interval (CI) and I-squared (I²) for heterogeneity were estimated. Sensitivity analyses were conducted.

RESULTS

Thirteen studies (n = 1022) were included in the meta-analysis. Exercise resulted in less depressive symptoms immediately after the exercise program ended, standardized mean difference = -0.13 [95% CI = -0.26, -0.01], I² = 6%, p = 0.03, but these effects were not retained with longer term follow-up. Exercise appeared to have a positive effect on depressive symptoms across both the subacute (≤6 months post stroke) and chronic stage of recovery (>6 months). There was a significant effect of exercise on depressive symptoms when higher intensity studies were pooled, but not for lower intensity exercise protocols. Antidepressant medication use was not documented in the majority of studies and thus, its potential confounding interaction with exercise could not be assessed.

CONCLUSIONS

Exercise may be a potential treatment to prevent or reduce depressive symptoms in individuals with subacute and chronic stroke.

What is the evidence for physical therapy poststroke? A systematic review and meta-analysis

BACKGROUND

Physical therapy (PT) is one of the key disciplines in interdisciplinary stroke rehabilitation. The aim of this systematic review was to provide an update of the evidence for stroke rehabilitation interventions in the domain of PT.

METHODS AND FINDINGS

Randomized controlled trials (RCTs) regarding PT in stroke rehabilitation were retrieved through a systematic search. Outcomes were classified according to the ICF. RCTs with a low risk of bias were quantitatively analyzed. Differences between phases poststroke were explored in subgroup analyses. A best evidence synthesis was performed for neurological treatment approaches. The search yielded 467 RCTs (N = 25373; median PEDro score 6 [IQR 5-7]), identifying 53 interventions. No adverse events were reported. Strong evidence was found for significant positive effects of 13 interventions related to gait, 11 interventions related to arm-hand activities, 1 intervention for ADL, and 3 interventions for physical fitness. Summary Effect Sizes (SESs) ranged from 0.17 (95%CI 0.03-0.70; I(2) = 0%) for therapeutic positioning of the paretic arm to 2.47 (95%CI 0.84-4.11; I(2) = 77%) for training of sitting balance. There is strong evidence that a higher dose of practice is better, with SESs ranging from 0.21 (95%CI 0.02-0.39; I(2) = 6%) for motor function of the paretic arm to 0.61 (95%CI 0.41-0.82; I(2) = 41%) for muscle strength of the paretic leg. Subgroup analyses yielded significant differences with respect to timing poststroke for 10 interventions. Neurological treatment approaches to training of body functions and activities showed equal or unfavorable effects when compared to other training interventions. Main limitations of the present review are not using individual patient data for meta-analyses and absence of correction for multiple testing.

CONCLUSIONS

There is strong evidence for PT interventions favoring intensive high repetitive task-oriented and task-specific training in all phases poststroke. Effects are mostly restricted to the actually trained functions and activities. Suggestions for prioritizing PT stroke research are given.
