Abstract
BACKGROUND The impact of changes in physical activity after ischemic stroke (IS) on the subsequent myocardial infarction (MI) risk is not fully understood. We aimed to investigate the effects of changes in physical activity on the risk of MI after acute IS using data from the Korean National Health Insurance Services Database. METHODS 224,764 patients newly diagnosed with IS between 2010 and 2016 who underwent two serial biannual health checkups were included. The participants were divided into four categories according to changes in their physical activity: persistent non-exercisers, new exercisers, exercise dropouts, and exercise maintainers. The primary outcome was a new diagnosis of incident MI. Multivariable Cox proportional models were used to assess the effects of changes in exercise habits on the risk of MI. RESULTS After a median of 4.25 years of follow-up, 6,611 (2.94%) MI cases were observed. After adjusting for confounders, new exercisers and exercise maintainers were significantly associated with a lower risk of incident MI than persistent non-exercisers (aHR, 0.849; 95% CI, 0.792-0.911; P-value < 0.001; and aHR, 0.746; 95% CI, 0.696-0.801; P-value < 0.001, respectively). Effects were consistent across sexes, more pronounced in those > 65 years. Notably, any level of physical activity after stroke was associated with a reduced MI risk compared to no exercise. CONCLUSIONS In this nationwide cohort study, commencing or sustaining physical activity after an IS corresponded to a diminished likelihood of subsequent MI development. Advocating physical activity in ambulatory stroke survivors could potentially attenuate the prospective risk of MI.

Abstract
BACKGROUND Transcranial direct current stimulation (tDCS) seems to be a potential tool to optimize the long-term effects of multimodal physical training (MPT) on fitness components in post-stroke patients. OBJECTIVE We investigated the effects of cortical tDCS combined with MPT on motor function reflected by strength, motor performance, and cardiorespiratory capacity in chronic stroke patients. METHODS This double-blind randomized controlled trial included 18 volunteers (55 ± 10 y, 72 ± 13 kg), who underwent MPT preceded by either sham stimulation (SHAM) or 2 mA bi-hemispheric tDCS. MPT consisted of 24 sessions of 60-70 min performed 2 d/wk within 12-16 weeks, with individualized intensity. Outcomes were Fugl-Meyer scores for lower limbs (FM-LL), and total (FM-Total); speed in the 10-m walk test (10MWT); oxygen uptake and work output at maximal effort (VO2max and Wmax), and gas exchange threshold (VO2-GET and W-GET); peak torque of isokinetic knee extension (PT-EXT) and flexion (PT-FLEX) of paretic and non-paretic limbs; bilateral strength deficit during knee extension (DS-EXT) and flexion (DS-FLEX). RESULTS Pre- vs. post-intervention improvements were detected in tDCS vs. SHAM (p < 0.05) for FM-total (29.6% vs. 15.9%; effect size [ES] = 0.78), FM-LL (35.9% vs. 9.0%; ES = 1.23), 10MWT (10.6% vs. 3.8%; ES = 0.67), Wmax (75.0% vs. 4.3%; ES = 1.68), W-GET (91.6% vs. 12.4%; ES = 1.62), PT-EXT (25.6% vs. -6.5%; ES = 1.94) and PT-FLEX (26.3% vs. 9.8%; ES = 0.65) of the paretic limb, and DS-EXT (-13.7% vs. 2.5; ES = 1.43). CONCLUSION Bi-hemispheric cortical tDCS optimized the effects of MPT performed with moderate volume and intensity upon muscle strength, motor function, and cardiorespiratory performance in stroke hemiparetic survivors.

Abstract
OBJECTIVE To address the fact that Black adults (BAs) experience significantly greater stroke burden than the general population, we conducted a systematic literature review which described evidence-based interventions targeting secondary stroke risk reduction in BAs. DATA SOURCE Publications were selected from PubMed, Ovid, Cochrane, and Web of Science databases. We included peer-reviewed, longitudinal, English-language studies performed in the USA which reported results for BAs separately and had adult participants who had experienced stroke-related events. RESULTS Six of the 7 studies employed behavioral interventions which promoted education on stroke risk factors, problem-solving skills, and healthy-coping strategies. These studies demonstrated improvements in one or more biologic outcomes including cholesterol control and systolic blood pressure. CONCLUSIONS Existing interventions on secondary stroke risk reduction approaches are effective in reducing secondary stroke risk among BAs, especially in individuals with poorly controlled blood pressure at baseline. However, additional research is needed because the current approaches may limit generalizability.

Abstract
OBJECTIVE To investigate the effects of a 12-week movement-to-music (M2M) intervention on physical and psychosocial outcomes in people poststroke. DESIGN Two-arm randomized controlled trial. SETTING A community-based fitness facility. PARTICIPANTS Participants (N=47) with stroke between 18 and 65 years old were randomized to M2M (n=23) or waitlist control (n=24). INTERVENTIONS Participants in M2M completed 3 60-minute exercise sessions per week for 12 weeks. Controls received biweekly educational newsletters via mail. MAIN OUTCOME MEASURES Primary outcomes included Six-Minute Walk Test (6MWT, in meters), Five Times Sit-to-Stand Test (FTSST, in seconds) and Timed Up and Go (TUG, in seconds). Secondary outcomes were self-reported measures using Patient-Reported Outcomes Measurement Information System Fatigue and Pain Interference Short Form 8a. Outcomes were collected at baseline and postintervention. Analyses involved descriptive statistics and adjusted linear mixed models. RESULTS Mixed models adjusted for the respective baseline values and demographic variables showed that M2M participants had longer 6MWT distance (least square mean difference [LSM], 14.5; 95% confidence interval [CI], -12.9 to 42.0), more FTSST time (LSM, 2.0; 95% CI, -4.5 to 8.5), and less fatigue (LSM, -3.0; 95% CI, -7.2 to 1.2) compared with controls postintervention. When controlling for baseline TUG and demographic variables, there was a larger increase in 6MWT distance (LSM, 37.9; 95% CI, -22.7 to 98.6), lower FTSST time (LSM, -6.1; 95% CI, -18.5 to 6.2), and decrease in fatigue (LSM, -6.5; 95% CI, -13.1 to 0.2) in the M2M group compared with controls. Moderate effect sizes were observed for improving 6MWT (d=0.6), FTSST (d=-0.6), and fatigue (d=-0.6). There was no group difference in change in TUG time and pain interference, with trivial effect sizes (d=-0.1). CONCLUSION M2M may be a valuable exercise form for adults with stroke. Future studies are needed to determine optimal exercise doses for improving health and function in this population.

Task-Oriented Circuit Training as an Alternative to Ergometer-Type Aerobic Exercise Training after Stroke. J Clin Med 2021; 10:jcm10112423. [PMID: 34070731 PMCID: PMC8198652 DOI: 10.3390/jcm10112423] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 05/25/2021] [Accepted: 05/26/2021] [Indexed: 11/17/2022] Open
Abstract
Moderate-intensity aerobic exercise training is an important treatment strategy to enhance functional recovery and decrease cardiometabolic risk factors after stroke. However, stroke related impairments limit access to ergometer-type exercise. The aims of the current study were (1) to evaluate whether our task-oriented circuit training protocol (intermittent functional training; IFT) could be used to sustain moderate-intensity aerobic workloads over a 10-week intervention period, and (2) to investigate its preliminary effects on cardiorespiratory fitness and metabolic profiles compared to constant-load ergometer-type exercise (CET). Forty chronic hemiparetic stroke survivors were randomized to receive 30 sessions of IFT or CET over ten weeks. Similar proportions of participants were randomized to IFT (7/19) and CET (9/18) sustained workloads associated with moderate-intensity aerobic exercise over the study period (p = 0.515). However, CET was associated with more substantial changes in maximal oxygen uptake (MD = 2.79 mL min−1 kg−1 CI: 0.84 to 4.74) compared to IFT (MD = 0.62 mL min−1 kg−1 CI: −0.38 to 1.62). Pre to post changes in C-reactive protein (−0.9 mg/L; p =0.017), short-term glycemia (+14.7 µmol/L; p = 0.026), and resting whole-body carbohydrate oxidation (+24.2 mg min−1; p = 0.046) were observed when considering both groups together. Accordingly, IFT can replicate the aerobic intensities sustained during traditional ergometer-type exercise training. More work is needed to evaluate the dose–response effects of such task-oriented circuit training protocols on secondary prevention targets across the continuum of stroke recovery.

J Stroke Cerebrovasc Dis 2019; 29:104498.

Abstract
BACKGROUND Cardiorespiratory fitness, measured as peak oxygen consumption, is a potent predictor of stroke risk. Muscle weakness is the most prominent impairment after stroke and is directly associated with reduced walking capacity. There is a lack of recommendations for optimal combined aerobic training and resistance training for those patients. The purpose of this study was to systematically review and quantify the effects of exercise training on cardiorespiratory fitness, muscle strength, and walking capacity after stroke. METHODS Five electronic databases were searched (until May 2019) for studies that met the following criteria: (1) adult humans with a history of stroke who ambulate independently; (2) structured exercise intervention based on combined aerobic training and resistance training; and (3) measured cardiorespiratory fitness, muscle strength, and/or walking capacity. RESULTS Eighteen studies (602 participants, average age 62 years) met the inclusion criteria. Exercise training significantly improved all 3 outcomes. In subgroup analyses for cardiorespiratory fitness, longer training duration was significantly associated with larger effect size. Likewise, for muscle strength, moderate weekly frequency and lower training volume were significantly associated with larger effect size. Furthermore, in walking capacity, moderate weekly frequency and longer training duration were significantly associated with larger effect size. CONCLUSIONS These results suggest that an exercise program consisting of moderate-intensity, 3 days per week, for 20 weeks should be considered for greater effect on cardiorespiratory fitness, muscle strength, and walking capacity in stroke patients.

Abstract
Background. As stroke survival improves, there is an increasing need for effective, low-cost programs to reduce deconditioning and improve mobility. Objective. To conduct a phase II trial examining whether the community-based Italian Adaptive Physical Activity exercise program for stroke survivors (APA-Stroke) is safe, effective, and feasible in the United States. Methods. In this single-blind, randomized controlled trial, 76 stroke survivors with mild to moderate hemiparesis >6 months were randomized to either APA-Stroke (N = 43) or Sittercise (N = 33). APA-Stroke is a progressive group exercise regimen tailored to hemiparesis that includes walking, strength, and balance training. Sittercise, a seated, nonprogressive aerobic upper body general exercise program, served as the control. Both interventions were 1 hour, 3 times weekly, in 5 community locations, supervised by exercise instructors. Results. A total of 76 participants aged 63.9 ± 1.2 years, mean months poststroke 61.8 ± 9.3, were included. There were no serious adverse events; completion rates were 58% for APA-Stroke, 70% for Sittercise. APA-Stroke participants improved significantly in walking speed. Sample size was inadequate to demonstrate significant between-group differences. Financial and logistical feasibility of the program has been demonstrated. Ongoing APA classes have been offered to >200 participants in county Senior Centers since study completion. Conclusion. APA-Stroke shows great promise as a low-cost, feasible intervention. It significantly increased walking speed. Safety and feasibility in the US context are demonstrated. A pivotal clinical trial is required to determine whether APA-Stroke should be considered standard of care.

Abstract
INTRODUCTION Rates of physical inactivity among people with physical disabilities are substantially higher than in the general population and access to home-based tailored exercise programmes is almost non-existent. Using a theory-driven eHealth platform, an innovative exercise programme referred to as movement-to-music (M2M) will be delivered as a customised, home-based exercise intervention for adults with mobility disabilities. METHODS AND ANALYSIS Participants are being recruited for this type 1 hybrid design based effectiveness trial through outpatient clinics at a large rehabilitation centre and randomised to one of three groups: (1) M2M, (2) M2M plus social networking (M2Mplus) and (3) attention control (AC). The intervention includes a 12-week adoption phase, 12-week transition phase and 24-week maintenance phase, at which the collection of objective measures on exercise, fitness and self-reported measures on health will be obtained at the start of each phase and at follow-up. The study compares the effectiveness of M2M and M2Mplus in increasing physical activity (primary outcome), adherence, fitness and physical functioning compared with the AC group and examines the mediators and moderators of the treatment effect. ETHICS AND DISSEMINATION The Institutional Review Board of The University of Alabama at Birmingham granted full approval: (IRB-160923002). Dissemination of findings will include publication in peer-reviewed journals, presentations at regional, national and/or international meetings, and the National Center on Health, Physical Activity and Disability (NCHPAD, www.nchpad.org). This study will strengthen our understanding of the potential benefits of eHealth exercise interventions for people with physical disabilities and build on strategies that aim to recruit larger samples in exercise trials.

Abstract
BACKGROUND Treadmill training, with or without body weight support using a harness, is used in rehabilitation and might help to improve walking after stroke. This is an update of the Cochrane review first published in 2003 and updated in 2005 and 2014. OBJECTIVES To determine if treadmill training and body weight support, individually or in combination, improve walking ability, quality of life, activities of daily living, dependency or death, and institutionalisation or death, compared with other physiotherapy gait-training interventions after stroke. The secondary objective was to determine the safety and acceptability of this method of gait training. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register (last searched 14 February 2017), the Cochrane Central Register of Controlled Trials (CENTRAL) and the Database of Reviews of Effects (DARE) (the Cochrane Library 2017, Issue 2), MEDLINE (1966 to 14 February 2017), Embase (1980 to 14 February 2017), CINAHL (1982 to 14 February 2017), AMED (1985 to 14 February 2017) and SPORTDiscus (1949 to 14 February 2017). We also handsearched relevant conference proceedings and ongoing trials and research registers, screened reference lists, and contacted trialists to identify further trials. SELECTION CRITERIA Randomised or quasi-randomised controlled and cross-over trials of treadmill training and body weight support, individually or in combination, for the treatment of walking after stroke. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials, extracted data, and assessed risk of bias and methodological quality. The primary outcomes investigated were walking speed, endurance, and dependency. MAIN RESULTS We included 56 trials with 3105 participants in this updated review. The average age of the participants was 60 years, and the studies were carried out in both inpatient and outpatient settings. All participants had at least some walking difficulties and many could not walk without assistance. Overall, the use of treadmill training did not increase the chances of walking independently compared with other physiotherapy interventions (risk difference (RD) -0.00, 95% confidence interval (CI) -0.02 to 0.02; 18 trials, 1210 participants; P = 0.94; I² = 0%; low-quality evidence). Overall, the use of treadmill training in walking rehabilitation for people after stroke increased the walking velocity and walking endurance significantly. The pooled mean difference (MD) (random-effects model) for walking velocity was 0.06 m/s (95% CI 0.03 to 0.09; 47 trials, 2323 participants; P < 0.0001; I² = 44%; moderate-quality evidence) and the pooled MD for walking endurance was 14.19 metres (95% CI 2.92 to 25.46; 28 trials, 1680 participants; P = 0.01; I² = 27%; moderate-quality evidence). Overall, the use of treadmill training with body weight support in walking rehabilitation for people after stroke did not increase the walking velocity and walking endurance at the end of scheduled follow-up. The pooled MD (random-effects model) for walking velocity was 0.03 m/s (95% CI -0.05 to 0.10; 12 trials, 954 participants; P = 0.50; I² = 55%; low-quality evidence) and the pooled MD for walking endurance was 21.64 metres (95% CI -4.70 to 47.98; 10 trials, 882 participants; P = 0.11; I² = 47%; low-quality evidence). In 38 studies with a total of 1571 participants who were independent in walking at study onset, the use of treadmill training increased the walking velocity significantly. The pooled MD (random-effects model) for walking velocity was 0.08 m/s (95% CI 0.05 to 0.12; P < 0.00001; I2 = 49%). There were insufficient data to comment on any effects on quality of life or activities of daily living. Adverse events and dropouts did not occur more frequently in people receiving treadmill training and these were not judged to be clinically serious events. AUTHORS' CONCLUSIONS Overall, people after stroke who receive treadmill training, with or without body weight support, are not more likely to improve their ability to walk independently compared with people after stroke not receiving treadmill training, but walking speed and walking endurance may improve slightly in the short term. Specifically, people with stroke who are able to walk (but not people who are dependent in walking at start of treatment) appear to benefit most from this type of intervention with regard to walking speed and walking endurance. This review did not find, however, that improvements in walking speed and endurance may have persisting beneficial effects. Further research should specifically investigate the effects of different frequencies, durations, or intensities (in terms of speed increments and inclination) of treadmill training, as well as the use of handrails, in ambulatory participants, but not in dependent walkers.

Abstract
BACKGROUND Circuit class therapy (CCT) offers a supervised group forum for people after stroke to practise tasks, enabling increased practice time without increasing staffing. This is an update of the original review published in 2010. OBJECTIVES To examine the effectiveness and safety of CCT on mobility in adults with stroke. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register (last searched January 2017), CENTRAL (the Cochrane Library, Issue 12, 2016), MEDLINE (1950 to January 2017), Embase (1980 to January 2017), CINAHL (1982 to January 2017), and 14 other electronic databases (to January 2017). We also searched proceedings from relevant conferences, reference lists, and unpublished theses; contacted authors of published trials and other experts in the field; and searched relevant clinical trials and research registers. SELECTION CRITERIA Randomised controlled trials (RCTs) including people over 18 years old, diagnosed with stroke of any severity, at any stage, or in any setting, receiving CCT. DATA COLLECTION AND ANALYSIS Review authors independently selected trials for inclusion, assessed risk of bias in all included studies, and extracted data. MAIN RESULTS We included 17 RCTs involving 1297 participants. Participants were stroke survivors living in the community or receiving inpatient rehabilitation. Most could walk 10 metres without assistance. Ten studies (835 participants) measured walking capacity (measuring how far the participant could walk in six minutes) demonstrating that CCT was superior to the comparison intervention (Six-Minute Walk Test: mean difference (MD), fixed-effect, 60.86 m, 95% confidence interval (CI) 44.55 to 77.17, GRADE: moderate). Eight studies (744 participants) measured gait speed, again finding in favour of CCT compared with other interventions (MD 0.15 m/s, 95% CI 0.10 to 0.19, GRADE: moderate). Both of these effects are considered clinically meaningful. We were able to pool other measures to demonstrate the superior effects of CCT for aspects of walking and balance (Timed Up and Go: five studies, 488 participants, MD -3.62 seconds, 95% CI -6.09 to -1.16; Activities of Balance Confidence scale: two studies, 103 participants, MD 7.76, 95% CI 0.66 to 14.87). Two other pooled balance measures failed to demonstrate superior effects (Berg Blance Scale and Step Test). Independent mobility, as measured by the Stroke Impact Scale, Functional Ambulation Classification and the Rivermead Mobility Index, also improved more in CCT interventions compared with others. Length of stay showed a non-significant effect in favour of CCT (two trials, 217 participants, MD -16.35, 95% CI -37.69 to 4.99). Eight trials (815 participants) measured adverse events (falls during therapy): there was a non-significant effect of greater risk of falls in the CCT groups (RD 0.03, 95% CI -0.02 to 0.08, GRADE: very low). Time after stroke did not make a difference to the positive outcomes, nor did the quality or size of the trials. Heterogeneity was generally low; risk of bias was variable across the studies with poor reporting of study conduct in several of the trials. AUTHORS' CONCLUSIONS There is moderate evidence that CCT is effective in improving mobility for people after stroke - they may be able to walk further, faster, with more independence and confidence in their balance. The effects may be greater later after the stroke, and are of clinical significance. Further high-quality research is required, investigating quality of life, participation and cost-benefits, that compares CCT with standard care and that also investigates the influence of factors such as stroke severity and age. The potential risk of increased falls during CCT needs to be monitored.

Abstract
OBJECTIVE To compare the immediate effects of conventional treadmill gait and guidance tubing gait (GTG) on electromyographic neuromuscular imbalance and knee joint kinematics in hemiparetic gait. DESIGN Case-control study. SETTING University medical center. PARTICIPANTS Participants (N=33; 19 men, 14 women) were patients with hemiparetic stroke (n=18 [experimental]; mean age ± SD, 39.2±16.8y) and healthy controls (n=15; mean age ± SD, 26.3±2.6y). INTERVENTIONS The GTG was provided for approximately 30 minutes and involved application of an assistive guidance force using the tubing, specifically to improve knee joint stabilization during midstance and increase knee joint flexion during midswing phase. MAIN OUTCOME MEASURES Clinical tests included the Korean Mini-Mental State Examination, Modified Ashworth Scale, Berg Balance Scale, manual muscle test, and knee joint range of motion and sensory tests. Knee joint muscle electromyographic and kinematic analyses were determined at pretest and posttest. RESULTS After the intervention, the experimental group showed significantly greater improvements in balanced quadriceps and hamstring electromyographic coactivation and knee joint kinematics relative to the control group (P=.005). The GTG intervention decreased overactive hamstring activity (P=.018) and reciprocally increased quadriceps activity (P<.001). The knee joint kinematic analysis showed significant changes in the hemiparetic stroke group (P=.004). CONCLUSIONS This study demonstrates the effectiveness of the tubing gait condition to restore knee joint muscle imbalance and kinematics in individuals with hemiparetic stroke who present with an abnormal hyperextension knee gait.

Abstract
OBJECTIVE The purpose of this systematic review was to examine studies that examined the effectiveness of aerobic exercise interventions on mobility in long-term stroke survivors. DESIGN The authors searched electronic databases for randomized control trials between January 1995 and December 2014 investigating aerobic exercise interventions and mobility in stroke survivors after the subacute phase (>6 mos). Mobility was measured using objective functional fitness tests: 6-minute walk, 10-meter walk, and up-n-go. RESULTS Nine randomized control trials that compared aerobic exercise with a control group among stroke survivors (mean age, 56.95-68 yrs) were identified. Aerobic interventions lasted between 2 and 6 mos and primarily involved walking. Using the Comprehensive Meta-analysis software, it was found that two of the three mobility outcomes showed small to moderate effect sizes favoring the aerobic exercise group: 6-minute walk (g = 0.366, P < 0.001) and 10-meter walk (g = 0.411, P = 0.002), while the up-n-go test was not significant (g = -0.150, P = 0.330). CONCLUSION These findings demonstrate that stroke survivors may continue to benefit from aerobic exercise after the subacute phase. Future research needs to examine the precise dose and recommendation for aerobic exercise, test other exercise modalities, and use larger samples to thoroughly determine long-term exercise effects on mobility in this population.

Facilitating Community-Based Exercise for People With Stroke: Cross-Sectional e-Survey of Physical Therapist Practice and Perceived Needs. Phys Ther 2016; 96:469-78.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND Peak aerobic capacity (VO2 peak) is severely worsened after disabling stroke, having serious implications for function, metabolism, and ongoing cardiovascular risk. Work from our laboratory and others has previously shown that modest improvements in VO2 peak are possible in stroke participants with aerobic exercise training. The purpose of the current investigation was to test the extent to which greater enhancements in VO2 peak after stroke are possible using a treadmill protocol with far greater emphasis on intensity progression compared with a protocol without such emphasis. METHODS Using a randomized design, we compared stroke survivors engaged in higher intensity treadmill training (HI-TM, 80% heart rate reserve [HRR]) with those undergoing lower intensity treadmill training (LO-TM, 50% HRR). Measured outcomes were change in VO2 peak, 6-minute walk distance (6MWD), 30-ft walk times (30WT), and 48-hour step counts (48SC). LO-TM participants trained for a longer period of time per session in an effort to approximately match workload/caloric expenditure. Participants were randomized with stratification according to age and baseline walking capacity. RESULTS HI-TM participants (n = 18) had significantly greater gains in VO2 peak (+34%) than LO-TM participants (n = 16; +5%) across the 6-month intervention period (P = .001, group × time interaction). Conversely, there was no statistical difference between groups in the changes observed for 6MWD, 30WT, or 48SC. CONCLUSIONS HI-TM is far more effective than LO-TM for improving VO2 peak after disabling stroke. The magnitude of relative improvement for HI-TM was double compared with previous reports from our laboratory with probable clinical significance for this population.

Abstract
BACKGROUND Although whole-body vibration (WBV) has sparked tremendous research interest in neurorehabilitation, the cardiovascular responses to WBV in people with stroke remain unknown. OBJECTIVE The aim of this study was to determine the acute effects of different WBV protocols on oxygen consumption (V̇o2), heart rate (HR), rate of perceived exertion (RPE), blood pressure (BP), and rate-pressure product (RPP) during the performance of 6 different exercises among people with chronic stroke (time since onset ≥6 months). DESIGN A repeated-measures design was used. METHODS Each of the 48 participants experienced all 3 WBV protocols in separate sessions: (1) no WBV, (2) low-intensity WBV (peak acceleration=0.96 unit of gravity of Earth [g]), and (3) high-intensity WBV (1.61g). The order in which they encountered the WBV protocols was randomized, as was the order of exercises performed during each session. Oxygen consumption, HR, and RPE were measured throughout the study. Blood pressure and RPP were measured before and after each session. RESULTS Low-intensity and high-intensity WBV induced significantly higher V̇o2 by an average of 0.69 and 0.79 mL/kg/min, respectively, compared with the control condition. These protocols also increased HR by an average of 4 bpm. The 2 WBV protocols induced higher RPE than the control condition during static standing exercise only. Although the diastolic and systolic BP and RPP were increased at the end of each exercise session, the addition of WBV had no significant effect on these variables. LIMITATIONS The results are generalizable only to ambulatory and community-dwelling people with chronic stroke. CONCLUSIONS Addition of high- and low-intensity WBV significantly increased the V̇o2 and HR, but the increase was modest. Thus, WBV should not pose any substantial cardiovascular hazard in people with chronic stroke.

Abstract
PURPOSE This study investigated the physiological responses of stroke survivors to a 16-week program of moderate aerobic and anaerobic exercise. METHOD Forty participants who were a minimum of 6 months post stroke underwent physiological testing over the course of 2 days that included a maximal VO(2) stress test, a Biodex strength assessment, and a blood lipid panel. The participants were then randomly assigned to two groups, an aerobic training only (ATO) group and an aerobic and strength training (A&ST) group. Both groups were then required to exercise aerobically for 20 minutes for 3 days a week at a moderate intensity for 16 weeks. Only the A&ST group was required to do a series of eight strength-training activities as part of their exercise protocol. Once the 16-week protocol was completed, all tests were repeated. These results were compared to the pretest data. RESULTS Statistically significant changes in VO(2max) were noted in the A&ST group, while positive but not significant changes were noted in the ATO group. Both groups saw significant increases in knee flexion but not in knee extension. The A&ST group showed significant increases in both shoulder flexion and extension, while the ATO group only had significant increases in shoulder extension. CONCLUSION We concluded that aerobic exercise produced positive metabolic changes in both groups, but only the A&ST group had statistically significant changes. Both groups demonstrated significant changes in functional strength, but the A&ST group experienced larger increases, likely due to the strength component of their training protocol.

Abstract
Stroke patients have profound cardiovascular and muscular deconditioning, with metabolic fitness levels that are about half those found in age-matched sedentary controls. Physical deconditioning, along with elevated energy demands of hemiparetic gait, define a detrimental combination termed diminished physiological fitness reserve that can greatly limit that can greatly limit performance of activities of daily living. The physiological features that underlie worsening metabolic fitness in the chronic phase of stroke include gross muscular atrophy, altered muscle molecular phenotype, increased intramuscular area fat, elevated tissue inflammatory markers, and diminished peripheral blood flow dynamics. Epidemiological evidence further suggests that the reduced cardiovascular fitness and secondary biological changes in muscle may propagate components of the metabolic syndrome, conferring added morbidity and mortality risk. This article reviews some of the consequences of poor fitness in chronic stroke and the potential biological underpinnings that support a rationale for more aggressive approaches to exercise therapy in this population.

Abstract
Stroke is the leading cause of disability in older Americans. Each year 750,000 Americans suffer a stroke, two thirds of whom are left with neurological deficits that persistently impair function. Principal among them is hemiparetic gait that limits mobility and increases fall risk, promoting a sedentary lifestyle. These events propagate disability by physical deconditioning and "learned non-use," with further functional declines accelerated by the sarcopenia and fitness decrements of advancing age. Conventional rehabilitation care typically provides little or no structured therapeutic exercise beyond the subacute stroke recovery period, based on natural history studies showing little or no further functional motor recovery beyond 6 months after stroke. Emerging evidence suggests that new models of task-oriented exercise have the potential to improve motor function even years after stroke. This article presents treadmill as a task-oriented training paradigm to optimize locomotor relearning while eliciting cardiovascular conditioning in chronic stroke patients. Protocols for exercise testing and longitudinal aerobic training progression are presented that provide fundamental formulas that safely approach the complex task of customizing aerobic training to gait deficit severity in the high CVD risk stroke population. The beneficial effects of 6 months task-oriented treadmill exercise on cardiovascular-metabolic fitness, energy cost of hemiparetic gait, ADL mobility task performance, and leg strength are discussed with respect to the central and peripheral neuromuscular adaptations targeted by the training. Collectively, these findings constitute one initial experience in a much broader neuroscience and exercise rehabilitation development of task-oriented training paradigms that offer a multisystems approach to improving both neurological and cardiovascular health outcomes in the chronic stroke population.

Abstract
[Purpose] The purpose of this study was to determine which ankle position most influences
knee extensor strength in training programs for strengthening the knee extensors using
three different active ankle positions. [Subjects] Twenty-one healthy adults (6 males and
15 females) participated in this study. [Methods] Subjects were trained isokinetically in
knee extension and flexion at 70 or 80% of 1RM under three actively and naturally fixed,
contracted ankle conditions: dorsiflexion, plantarflexion, and resting position. After
each group successfully executed the training four times a week for three weeks, mean peak
torque (PT) and total work (TW) variables were measured and compared at 60°/sec and
180°/sec among the three groups. [Results] Significant differences were revealed in knee
extensor TW at 60°/sec, PT and TW at 180°/sec, with the greatest PT and TW observed with
the ankle in active dorsiflexion position. [Conclusion] These results suggest that active
ankle dorsiflexion in a knee strength training program may be more effective at increasing
knee extensor strength than a resting or plantarflexion position.

Abstract
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.

Abstract
BACKGROUND Treadmill training, with or without body weight support using a harness, is used in rehabilitation and might help to improve walking after stroke. This is an update of a Cochrane review first published in 2005. OBJECTIVES To determine if treadmill training and body weight support, individually or in combination, improve walking ability, quality of life, activities of daily living, dependency or death, and institutionalisation or death, compared with other physiotherapy gait training interventions after stroke. The secondary objective was to determine the safety and acceptability of this method of gait training. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register (last searched June 2013), the Cochrane Central Register of Controlled Trials (CENTRAL) and the Database of Reviews of Effects (DARE) (The Cochrane Library 2013, Issue 7), MEDLINE (1966 to July 2013), EMBASE (1980 to July 2013), CINAHL (1982 to June 2013), AMED (1985 to July 2013) and SPORTDiscus (1949 to June 2013). We also handsearched relevant conference proceedings and ongoing trials and research registers, screened reference lists and contacted trialists to identify further trials. SELECTION CRITERIA Randomised or quasi-randomised controlled and cross-over trials of treadmill training and body weight support, individually or in combination, for the treatment of walking after stroke. DATA COLLECTION AND ANALYSIS Two authors independently selected trials, extracted data and assessed methodological quality. The primary outcomes investigated were walking speed, endurance and dependency. MAIN RESULTS We included 44 trials with 2658 participants in this updated review. Overall, the use of treadmill training with body weight support did not increase the chances of walking independently compared with other physiotherapy interventions (risk difference (RD) -0.00, 95% confidence interval (CI) -0.02 to 0.02; P = 0.94; I² = 0%). Overall, the use of treadmill training with body weight support in walking rehabilitation for patients after stroke increased the walking velocity and walking endurance significantly. The pooled mean difference (MD) (random-effects model) for walking velocity was 0.07 m/s (95% CI 0.01 to 0.12; P = 0.02; I² = 57%) and the pooled MD for walking endurance was 26.35 metres (95% CI 2.51 to 50.19; P = 0.03; I² = 60%). Overall, the use of treadmill training with body weight support in walking rehabilitation for patients after stroke did not increase the walking velocity and walking endurance at the end of scheduled follow-up significantly. The pooled MD (random-effects model) for walking velocity was 0.04 m/s (95% CI -0.06 to 0.14; P = 0.40; I² = 40%) and the pooled MD for walking endurance was 32.36 metres (95% CI -3.10 to 67.81; P = 0.07; I² = 63%). However, for ambulatory patients improvements in walking endurance lasted until the end of scheduled follow-up (MD 58.88 metres, 95% CI 29.10 to 88.66; P = 0.0001; I² = 0%). Adverse events and drop outs did not occur more frequently in people receiving treadmill training and these were not judged to be clinically serious events. AUTHORS' CONCLUSIONS Overall, people after stroke who receive treadmill training with or without body weight support are not more likely to improve their ability to walk independently compared with people after stroke not receiving treadmill training, but walking speed and walking endurance may improve. Specifically, stroke patients who are able to walk (but not people who are not able to walk) appear to benefit most from this type of intervention. This review found that improvements in walking endurance in people able to walk may have persisting beneficial effects. Further research should specifically investigate the effects of different frequencies, durations or intensities (in terms of speed increments and inclination) of treadmill training, as well as the use of handrails, in ambulatory patients, but not in dependent walkers.

Abstract
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. The secondary aims were to determine the effects of training on physical fitness, mobility, physical function, quality of life, mood, and incidence of adverse events. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register (last searched January 2013), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 12: searched January 2013), MEDLINE (1966 to January 2013), EMBASE (1980 to January 2013), CINAHL (1982 to January 2013), SPORTDiscus (1949 to January 2013), and five additional databases (January 2013). 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, with no intervention, a non-exercise intervention, or usual care in stroke survivors. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials, assessed quality, and extracted data. We analysed data using random-effects meta-analyses. Diverse outcome measures limited the intended analyses. MAIN RESULTS We included 45 trials, involving 2188 participants, which comprised cardiorespiratory (22 trials, 995 participants), resistance (eight trials, 275 participants), and mixed training interventions (15 trials, 918 participants). Nine deaths occurred before the end of the intervention and a further seven at the end of follow-up. No dependence data were reported. Diverse outcome measures made data pooling difficult. Global indices of disability show a tendency to improve after cardiorespiratory training (standardised mean difference (SMD) 0.37, 95% confidence interval (CI) 0.10 to 0.64; P = 0.007); benefits at follow-up and after mixed training were unclear. There were insufficient data to assess the effects of resistance training.Cardiorespiratory training involving walking improved maximum walking speed (mean difference (MD) 7.37 metres per minute, 95% CI 3.70 to 11.03), preferred gait speed (MD 4.63 metres per minute, 95% CI 1.84 to 7.43), walking capacity (MD 26.99 metres per six minutes, 95% CI 9.13 to 44.84), and Berg Balance scores (MD 3.14, 95% CI 0.56 to 5.73) 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), walking capacity (MD 41.60 metres per six minutes, 95% CI 25.25 to 57.95), and also pooled balance scores but the evidence is weaker (SMD 0.26 95% CI 0.04 to, 0.49). Some mobility benefits also persisted at the end of follow-up. The variability and trial quality hampered the assessment of the reliability and generalisability of the observed results. AUTHORS' CONCLUSIONS The effects of training on death and dependence after stroke are unclear. Cardiorespiratory training reduces disability after stroke and this may be mediated by improved mobility and balance. There is sufficient evidence to incorporate cardiorespiratory and mixed training, involving walking, within post-stroke rehabilitation programs to improve the speed and tolerance of walking; improvement in balance may also occur. There is insufficient evidence to support the use of resistance training. Further well-designed trials are needed to determine the optimal content of the exercise prescription and identify long-term benefits.

Abstract
BACKGROUND Cardiorespiratory fitness is low after stroke. Improving fitness has the potential to improve function and reduce secondary cardiovascular events. OBJECTIVE . This review with meta-analysis aims to identify characteristics and determine the effectiveness of interventions to improve cardiorespiratory fitness after stroke. METHODS A systematic search and review with meta-analysis was undertaken. Key inclusion criteria were the following: peer-reviewed articles published in English, adult stroke survivors, an intervention with the potential to improve cardiorespiratory fitness, and peak oxygen consumption (VO2peak) assessed preintervention and postintervention via a progressive aerobic exercise test. RESULTS From 3209 citations identified, 28 studies were included, reporting results for 920 participants. Studies typically included chronic, ambulant participants with mild to moderate deficits; used an aerobic or mixed (with an aerobic component) intervention; and prescribed 3 sessions per week for 30 to 60 minutes per session at a given intensity. Baseline VO2peak values were low (8-23 mL/kg/min). Meta-analysis of the 12 randomized controlled trials demonstrated overall improvements in VO2peak of 2.27 (95% confidence interval = 1.58, 2.95) mL/kg/min postintervention. A similar 10% to 15% improvement occurred with both aerobic and mixed interventions and in shorter (≤ 3 months) and longer (>3 months) length programs. Only 1 study calculated total dose received and only 1 included long-term follow-up. CONCLUSIONS The results demonstrate that interventions with an aerobic component can improve cardiorespiratory fitness poststroke. Further investigation is required to determine effectiveness in those with greater impairment and comorbidities, optimal timing and dose of intervention, whether improvements can be maintained in the longer term, and whether improved fitness results in better function and reduced risk of subsequent cardiovascular events.

Abstract
BACKGROUND This pilot study examined the effectiveness of a telephone-based intervention to increase physical activity in obese African American women with mobility disabilities by targeting the removal of barriers to participation. METHODS Severely obese (mean body mass index [BMI] = 49.1 kg.m²) African American women (n = 33) with mobility disabilities completed a 6-month telephone-based physical activity coaching intervention. RESULTS The major environmental/facility barriers at preintervention were cost of the program (66.7%), lack of transportation (48.5%), not aware of fitness center in the area (45.5%), and lack of accessible facilities (45.5%). The major personal barriers were pain (63.6%), don't know how to exercise (45.5%), health concerns (39.4%), don't know where to exercise (39.4%), and lack of energy (36.4%). Despite only two personal barriers being significantly lower at posttest (don't know where to exercise and don't know how to exercise) (p < 0.01), total exercise time increased from < 6 minutes/day to 27 minutes/day at posttest (p < 0.001), and total physical activity time (structured exercise, leisure, indoor and outdoor household activity) increased from 26 minutes/day to 89 minutes/day at posttest (p < 0.001). CONCLUSIONS Interventions aimed at increasing physical activity participation among obese African American women with mobility disabilities should start with increasing their awareness/knowledge on where and how to exercise. Other reported barriers (e.g., cost, transportation, finding an accessible facility, health concerns, pain) may not be as critical to alter/remove as identifying where participants can exercise (i.e., home, outdoors, gym) and providing them with a variety of routines that can be performed safely in their desired setting.

Abstract
BACKGROUND Stroke is responsible for increasingly high rates of mortality and disability worldwide. Approximately two million people suffer from stroke for the first time in China each year. The high incidence (50%) of post-stroke disability brings a heavy burden to patients and their caregivers. Acupuncture has been widely used in the communities for post-stroke rehabilitation in China. The objective of this trial is to apply our acupuncture research achievement to treatment and evaluation of post-stroke hemiplegic patients in community. METHODS AND DESIGN A multicenter, randomized, controlled trial will be performed in Longhua Hospital and a number of community health service centers in Shanghai. A total of 124 patients (estimated sample size) with post-stroke hemiplegia will be randomly divided into an acupuncture group and a control group. The patients undergoing randomization should be stratified according to National Institutes of Health Stroke Scale score at baseline. Within the acupuncture group, different acupuncture protocols are administered to patients with flaccid paralysis or spastic paralysis based on the Ashworth Scale. Patients in the acupuncture group will also be treated with comprehensive rehabilitation therapy. The control group will be treated with comprehensive rehabilitation therapy only. The primary outcome measures are the Simplified Fugl-Meyer Motor Scale, the Modified Barthel Index, and the Burden of Stroke Scale. Secondary outcome measures are the modified Rankin Scale, the modified Ashworth Scale and the Stroke Scale of Traditional Chinese Medicine. Outcome measures will be performed after 4 and 8 weeks of treatment. The patients will be followed up after 6 months. DISCUSSION The results of this study are expected to demonstrate that our standardized acupuncture protocol for treating and evaluating post-stroke hemiplegic patients will improve motor function and lessen the burden of post-stroke patients within the communities. This will provide the evidence to support successful translation of acupuncture therapy for post-stroke hemiplegic patients in community hospital use. TRIAL REGISTRATION This trial was registered in Chinese Clinical Trial Registry with the registration number ChiCTR-TRC-11001347.

Abstract
Cardiorespiratory fitness programs are increasingly used in stroke rehabilitation. Maximal oxygen uptake is the gold standard measurement of cardiorespiratory fitness; however, no recent publications have collated evidence about maximal oxygen uptake levels following stroke. We therefore performed a systematic review of maximal oxygen uptake in stroke survivors, aiming to observe changes in levels over time, and associations with severity of stroke. We searched Medline and Embase until April 2011, and included cross-sectional studies, longitudinal studies, and baseline data from intervention trials. Studies had to recruit at least 10 stroke survivors, and report direct measurement of maximal/peak oxygen uptake. We then compared maximal oxygen uptake with published data from age and gender-matched controls. The search identified 3357 articles. Seventy-two full texts were retrieved, of which 41 met the inclusion criteria. Time since stroke ranged from 10 days to over seven-years. Peak oxygen uptake ranged from 8 to 22 ml/kg/min, which was 26–87% of that of healthy age- and gender-matched individuals. Stroke severity was mild in most studies. Three studies reported longitudinal changes; there was no clear evidence of change in peak oxygen uptake over time. Most studies recruited participants with mild stroke, and it is possible that cardiorespiratory fitness is even more impaired after severe stroke. Maximal oxygen uptake might have been overestimated, as less healthy and older stroke survivors may not tolerate maximal exercise testing. More studies are needed describing mechanisms of impaired cardiorespiratory fitness and longitudinal changes over time to inform the optimal ‘prescription’ of cardiorespiratory fitness programs for stroke survivors.

Abstract
OBJECTIVES To examine changes in cardiorespiratory fitness over the first year poststroke and explore the effect of prestroke patients' characteristics and stroke-related factors on this evolution. DESIGN Descriptive, longitudinal study with repeated measures of exercise capacity at 3, 6, and 12 months poststroke. SETTING Rehabilitation center and exercise testing laboratory. PARTICIPANTS Consecutive sample of patients with stroke (N=33; mean age ± SD, 59.0±11.3 y). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Peak oxygen consumption (VO(2)peak) and oxygen uptake efficiency slope (OUES) were determined during a symptom-limited graded cycle ergometer test at 3, 6, and 12 months poststroke. Age, sex, premorbid physical activity level, clinical history (smoking, diabetes mellitus, chronic pulmonary diseases, cardiovascular diseases, overweight, and hypertension), stroke type and area, side of lesion, and assessments of stroke severity were evaluated at intake. RESULTS Mean VO(2)peak ± SD was 18.1±6.6 mL·kg(-1)·min(-1), 19.8±8.0 mL·kg(-1)·min(-1), and 19.7±8.4 mL·kg(-1)·min(-1) at 3, 6, and 12 months poststroke. Values for OUES were 1575.3±638.3, 1710.7±710.3, and 1687.2±777.5, respectively. Mixed models showed no significant difference over time for VO(2)peak (P=.10), nor for the logarithm of OUES (P=.09). Stroke survivors at risk of deconditioning were premorbidly less active at work or in sport activities, diabetic, or initially more severely impaired. Combination of factors revealed that older patients with stroke and diabetes were less likely to improve on VO(2)peak and that older, women, diabetic nonsmokers improved less on log OUES. CONCLUSIONS Cardiorespiratory fitness was reduced from 3 to 12 months poststroke and on average did not significantly change over time. Further studies should elucidate methods of increasing cardiorespiratory fitness during stay in the rehabilitation center and how community-based aerobic exercise training postrehabilitation can be organized.

Abstract
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. The secondary aims were to determine the effects of training on physical fitness, mobility, physical function, quality of life, mood, and incidence of adverse events. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register (last searched April 2010), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, July 2010), MEDLINE (1966 to March 2010), EMBASE (1980 to March 2010), CINAHL (1982 to March 2010), SPORTDiscus (1949 to March 2010), and five additional databases (March 2010). 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, with no intervention, a non-exercise intervention, or usual care in stroke survivors. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials, assessed quality, and extracted data. We analysed data using random-effects meta-analyses. Diverse outcome measures limited the intended analyses. MAIN RESULTS We included 32 trials, involving 1414 participants, which comprised cardiorespiratory (14 trials, 651 participants), resistance (seven trials, 246 participants), and mixed training interventions (11 trials, 517 participants). Five deaths were reported at the end of the intervention and nine at the end of follow-up. No dependence data were reported. Diverse outcome measures made data pooling difficult. The majority of the estimates of effect were not significant. Cardiorespiratory training involving walking improved maximum walking speed (mean difference (MD) 8.66 metres per minute, 95% confidence interval (CI) 2.98 to 14.34), preferred gait speed (MD 4.68 metres per minute, 95% CI 1.40 to 7.96) and walking capacity (MD 47.13 metres per six minutes, 95% CI 19.39 to 74.88) at the end of the intervention. These training effects were retained at the end of follow-up. Mixed training, involving walking, increased preferred walking speed (MD 2.93 metres per minute, 95% CI 0.02 to 5.84) and walking capacity (MD 30.59 metres per six minutes, 95% CI 8.90 to 52.28) but effects were smaller and there was heterogeneity amongst the trial results. There were insufficient data to assess the effects of resistance training. The variability in the quality of included trials hampered the reliability and generalizability of the observed results. AUTHORS' CONCLUSIONS The effects of training on death, dependence, and disability after stroke are unclear. There is sufficient evidence to incorporate cardiorespiratory training involving walking within post-stroke rehabilitation programmes to improve speed, tolerance, and independence during walking. Further well-designed trials are needed to determine the optimal exercise prescription and identify long-term benefits.

Abstract
The role of physical activity in the prevention of stroke is of great interest due to the high mortality and significant impact of stroke-related morbidity on the individual and on healthcare resources. The use of physical activity as a therapeutic strategy to maximise functional recovery in the rehabilitation of stroke survivors has a growing evidence base. This narrative review examines the existing literature surrounding the use of exercise and physical therapy in the primary and secondary prevention of stroke. It explores the effect of gender, exercise intensities and the duration of observed benefit. It details the most recent evidence for physical activity in improving functional outcome in stroke patients. The review summaries the current guidelines and recommendations for exercise therapy and highlights areas in which further research and investigation would be useful to determine optimal exercise prescription for effective prevention and rehabilitation in stroke.

Abstract
Despite ongoing improvements in the acute treatment of cerebrovascular diseases and organization of stroke services, many stroke survivors are in need of neurorehabilitation, as more than two-thirds show persisting neurologic deficits. While early elements of neurorehabilitation are already taking place on the stroke unit, after the acute treatment, the patient with relevant neurologic deficits usually takes part in an organized inpatient multidisciplinary rehabilitation program and eventually continues with therapies in an ambulatory setting afterwards. A specialized multidisciplinary neurorehabilitation team with structured organization and processes provides a multimodal, intense treatment program for stroke patients which is adapted in detail to the individual goals of rehabilitation. There are many parallels between postlesional neuroplasticity (relearning) and learning in the development of individuals as well as task learning of healthy persons. One key principle of neurorehabilitation is the repetitive creation of specific learning situations to promote mechanisms of neural plasticity in stroke recovery. There is evidence of achieving a better outcome of neurorehabilitation with early initiation of treatment, high intensity, with specific goals and active therapies, and the coordinated work and multimodality of a specialized team. In this context, interdisciplinary goal-setting and regular assessments of the patient are important. Furthermore, several further potential enhancers of neural plasticity, e.g., peripheral and brain stimulation techniques, pharmacological augmentation, and use of robotics, are under evaluation.

Abstract
BACKGROUND AND PURPOSE Emerging evidence suggests that exercise may improve cognitive function in older adults. The purpose of this pilot study was to describe changes in measures of cognition and executive function in individuals with chronic stroke following participation in aerobic and strengthening exercise. METHODS A single-group, pretest-posttest design was used. Nine individuals with chronic stroke (mean age = 63.7 ± 9.1 years, mean time since stroke = 50.4 ± 37.9 months) completed a 12-week program of aerobic and strengthening exercise, 3 days per week. The primary outcome measures examined executive function (Digit Span Backwards and Flanker tests). Secondary measures examined various aspects of aerobic fitness (VO2peak and 6-minute walk distance) and function (Fugl-Meyer and 10-m walk speed). RESULTS Following the intervention, significant improvements were found in the Digit Span Backwards test (mean change = 0.56 ± 0.9 digits; P = 0.05), Fugl-Meyer score (mean change = 3.6 ± 5.7; P = 0.05), and Stroke Impact Scale total score (mean change = 33.8 ± 38.5; P = 0.02). A significant correlation was found between improved aerobic capacity and improved performance on the Flanker test (r = 0.74; P = 0.02). DISCUSSION The results of this study indicate that a 12-week aerobic and strengthening exercise program was associated with improvements in selected measures of executive function and functional capacity in people with stroke. Limitations of this study include the small sample size and lack of a comparison group. CONCLUSIONS This pilot study contributes to the emerging evidence that exercise improves cognition in people with stroke. These benefits indicate the need for future study with a larger group to have sufficient power to further explore these relationships.

Abstract
It is becoming increasingly clear that, if reorganization of brain function is to be optimal after stroke, there needs to be a reorganisation of the methods used in physical rehabilitation and the time spent in specific task practice, strength and endurance training, and aerobic exercise. Frequency and intensity of rehabilitation need to be increased so that patients can gain the energy levels and vigour necessary for participation in physical activity both during rehabilitation and after discharge. It is evident that many patients are discharged from inpatient rehabilitation severely deconditioned, meaning that their energy levels are too low for active participation in daily life. Physicians, therapists, and nursing staff responsible for rehabilitation practice should address this issue not only during inpatient rehabilitation but also after discharge by promoting and supporting community-based exercise opportunities. During inpatient rehabilitation, group sessions should be frequent and need to include specific aerobic training. Physiotherapy must take advantage of the training aids available, including exercise equipment such as treadmills, and of new developments in computerised feedback systems, robotics, and electromechanical trainers. For illustrative purposes, this paper focuses on the role of physiotherapists, but the necessary changes in practice and in attitude will require cooperation from many others.

Abstract
PURPOSE Stroke-related deficits can impede both functional performance and walking tolerance. Individuals with hemiparesis rely on the stronger limb during exercise and functional tasks. The single limb exercise (SLE) intervention was a unique training protocol that focused only on the hemiparetic limb. Our objective was to determine the effect of the SLE intervention on cardiorespiratory fitness parameters. METHODS Twelve participants (5 male) with a mean age of 60.6 +/- 14.5 years and 69.1 +/- 82.2 months post stroke participated in the training intervention. All participants performed SLE using the hemiparetic leg three times a week for 4 weeks. The nonhemiparetic limb served as the control limb and did not engage in SLE. Peak oxygen uptake (VO2 peak) and oxygen uptake (VO2) were measured at baseline and post intervention in all 12 participants. At pre and post intervention, gait velocity was assessed in a subset of participants (n = 7) using the 10-m fast-walk test. RESULTS After the 4-week SLE training intervention, significant improvements were found for VO2 during submaximal work effort (P = .009) and gait velocity (n = 7) (P = .001). Peak oxygen uptake did not increase (P = .41) after the training intervention. CONCLUSION These data suggest that SLE training was an effective method for improving oxygen uptake and reducing energy expenditure during submaximal effort. Unilateral exercise focused on the hemiparetic leg may be an effective intervention strategy to consider for stroke rehabilitation.

Abstract
BACKGROUND Circuit class therapy (CCT) offers a supervised group forum for people after stroke to practise tasks, enabling increased practise time without increasing staffing. OBJECTIVES To examine the effectiveness and safety of CCT on mobility in adults with stroke. SEARCH STRATEGY We searched the Cochrane Stroke Group Trials Register (last searched October 2009), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 2, 2009), MEDLINE (1950 to November 2008), EMBASE (1980 to November 2008), CINAHL (1982 to November 2008) and 14 other electronic databases (to November 2008). We also searched proceedings from relevant conferences, reference lists and unpublished theses; contacted authors of published trials and other experts in the field; and searched relevant clinical trials and research registers. SELECTION CRITERIA Randomised or quasi-randomised controlled trials including people over 18 years old diagnosed with stroke of any severity, at any stage, or in any setting, receiving CCT. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials for inclusion, assessed methodological quality and extracted data. MAIN RESULTS We included six trials involving 292 participants. Participants were long-term stroke survivors living in the community or receiving inpatient rehabilitation. All could walk 10 metres with or without assistance. Four studies measured walking capacity and three measured gait speed, demonstrating that CCT was superior to the comparison intervention (Six Minute Walk Test: mean difference (MD), fixed 76.57 metres, 95% confidence interval (CI) 38.44 to 114.70, P < 0.0001; gait speed: MD, fixed 0.12 m/s, 95% CI 0.00 to 0.24, P = 004). Two studies measured balance, showing a superior effect in favour of CCT (Step Test: MD, fixed 3.00 steps, 95% CI 0.08 to 5.91, P = 0.04; activities-specific balance and confidence: MD, fixed 7.76, 95% CI 0.66 to 14.87, P = 0.03). Studies also measured other balance items showing no difference in effect. Length of stay (two studies) showed a significant effect in favour of CCT (MD, fixed -19.73 days, 95% CI -35.43 to -4.04, P = 0.01). Only two studies measured adverse events (falls during therapy): all were minor. AUTHORS' CONCLUSIONS CCT is safe and effective in improving mobility for people after moderate stroke and may reduce inpatient length of stay. Further research is required, investigating quality of life, participation and cost-benefits, that compares CCT to standard care and that also investigates the differential effects of stroke severity, latency and age.

Abstract
Background Despite the cardiovascular etiology of stroke, exercise and risk factor modification programs akin to cardiac rehabilitation (CR) are not available. This study aimed to establish the feasibility of adapting a CR model for individuals with mild to moderate stroke disability. A secondary objective was to determine the program's effects on aerobic and walking capacity, and stroke risk factors. Methods A repeated measures design was used with a 3-month baseline period and 6-month adapted CR intervention (n = 43, mean ± SD age 65 ± 12 years, 30 ± 28 months post stroke). Feasibility was determined by the number of participants who completed the study, occurrence of adverse events and frequency, duration and intensity of exercise performed. To determine effectiveness of the program, outcomes measured included aerobic capacity (VO2peak, ventilatory threshold), 6-Minute Walk Test (6MWT) distance, and risk factors. Descriptive statistics characterized the classes attended and number and intensity of exercise sessions. Paired t-tests, one-factor repeated measures analyses of variance contrasts and chi-square analyses were used to compare changes over time. Results Two participants withdrew during the baseline period. Of the remaining 41 participants who commenced the program, 38 (93%) completed all aspects. No serious adverse effects occurred. Post-intervention, VO2peak improved relative to the stable baseline period (P = 0.046) and the increase in ventilatory threshold approached significance (P = 0.062). Conclusions CR is feasible after stroke and may be adapted to accommodate for those with a range of post-stroke disability. It is effective in increasing aerobic capacity. CR may be an untapped opportunity for stroke survivors to access programs of exercise and risk factor modification to lower future event risk.

Abstract
BACKGROUND Fatigue is a commonly neglected issue despite the high incidence rate reported in people post-stroke. OBJECTIVE To explore the relationship between fatigue, aerobic fitness, and motor control in people with chronic stroke. METHODS Nine people post-stroke participated in this cross-sectional study (7 females, mean age = 56.8 (11.8) years, range 47-73, time post-stroke = 47.6 (51.2) months, range 11-140). Participants performed a six-minute-walk exercise in order to induce fatigue, followed immediately by a Fatigue Index (FI) scale to report fatigue at the moment. The distance walked (6MWD) was documented. On a separate visit, aerobic fitness was characterized by VO(2Peak) using a cycle-ergometer. In addition, Fugl-Meyer (FM) test was administered to assess motor control of the hemiparetic side. Pearson Product Correlation Coefficient and multiple linear regression were used to analyze the relationships between FI, VO(2Peak) and FM. RESULTS VO(2Peak) showed significant positive correlations with FM (r = .779, p = .013) and 6MWD (r = .726, p = .027). Fatigue index displayed significant negative correlations with VO(2Peak) (r = -.739, p = .023) and FM (r = -.873, p = .002), but not with 6MWD (r = -.620, p = .075). Using stepwise multiple regression, we found that that FM was an independent predictor of FI (p = .002) and explained 76.2% of variance in FI (R2 = .762). CONCLUSION Our data suggests that motor control capability may be a good predictor of fatigue in people post-stroke. Fatigue is a complex phenomenon; a quantifiable measure that is sensitive to multiple components is needed in order to distinguish the nature of fatigue and its contributing factors.

Abstract
Part I of this two-part introduction to this Special Issue on the practice of physical therapy in the 21st century outlines the epidemiological basis and rationale for evidence-informed physical therapy practice for addressing contemporary health priorities. This evidence emanates from the definition of health by the World Health Organization (WHO) and the International Classification of Functioning (ICF), and WHO and other international databases on the prevalence of lifestyle conditions. Lifestyle conditions include ischemic heart disease, smoking-related conditions, hypertension and stroke, obesity, diabetes, and cancer. Epidemiological data combined with evidence supporting the effectiveness of noninvasive interventions related to physical therapy to address these priorities (e.g., health education and exercise) are highly consistent with the promotion of health and wellness and the ICF. Given their commitment to exploiting effective noninvasive interventions, physical therapists are in a preeminent position to focus on prevention of these disabling and lethal conditions in every client or patient, their cure in some cases, as well as their management. Thus, a compelling argument can be made that clinical competencies in 21st century physical therapy need to include assessment of smoking and smoking cessation (or at least its initiation), basic nutritional assessment and counseling, recommendations for physical activity and exercise, stress assessment and basic stress reduction recommendations, and sleep assessment and basic sleep hygiene recommendations. The physical therapist can then make an informed clinical judgment regarding whether a client or patient needs to be referred to another professional related to one or more of these specialty areas. The prominence of physical therapy as an established health care profession and its unique pattern of practice (prolonged visits over prolonged periods of time) attest further to the fact that physical therapists are uniquely qualified to lead in the assault on lifestyle conditions. Evidence-based physical therapy practiced within the context of epidemiological indicators (i.e., evidence-informed practice) maximally empowers clinicians to promote lifelong health in every person and in turn, the health of communities. This vision of physical therapy's leading role in health promotion and health care in the 21st century holds the promise of reducing the need for invasive health interventions (drugs and surgery). Part II of this introduction describes evidence-based physical therapy practice within this context of evidence-informed practice.

Abstract
BACKGROUND Physical fitness is low after stroke. It is unknown whether improving physical fitness after stroke reduces disability. OBJECTIVES To determine whether fitness training (cardiorespiratory or strength, or both) after stroke reduces death, dependence and disability. The secondary aims were to determine the effects of fitness training on physical fitness, mobility, physical function, health status and quality of life, mood and incidence of adverse events. SEARCH STRATEGY We searched the Cochrane Stroke Group Trials Register (last searched March 2009), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2007), MEDLINE (1966 to March 2007), EMBASE (1980 to March 2007), CINAHL (1982 to March 2007), and six additional databases to March 2007. We handsearched relevant journals and conference proceedings, and screened bibliographies. We searched trials registers and contacted experts in the field. SELECTION CRITERIA We included randomised controlled trials if the aim of the intervention was to improve muscle strength or cardiorespiratory fitness, or both, and if the control groups comprised either no intervention, usual care or a non-exercise intervention. DATA COLLECTION AND ANALYSIS Two review authors determined trial eligibility and quality. One review author extracted outcome data at end of intervention and follow-up scores, or as change from baseline scores. Diverse outcome measures limited the intended analysis. MAIN RESULTS We included 24 trials, involving 1147 participants, comprising cardiorespiratory (11 trials, 692 participants), strength (four trials, 158 participants) and mixed training interventions (nine trials, 360 participants). Death was infrequent at the end of the intervention (1/1147) and follow up (8/627). No dependence data were reported. Diverse disability measures made meta-analysis difficult; the majority of effect sizes were not significant. Cardiorespiratory training involving walking, improved maximum walking speed (mean difference (MD) 6.47 metres per minute, 95% confidence interval (CI) 2.37 to 10.57), walking endurance (MD 38.9 metres per six minutes, 95% CI 14.3 to 63.5), and reduced dependence during walking (Functional Ambulation Categories MD 0.72, 95% CI 0.46 to 0.98). Current data include few strength training trials, and lack non-exercise attention controls, long-term training and follow up. AUTHORS' CONCLUSIONS The effects of training on death, dependence and disability after stroke are unclear. There is sufficient evidence to incorporate cardiorespiratory training, involving walking, within post-stroke rehabilitation in order to improve speed, tolerance and independence during walking. Further trials are needed to determine the optimal exercise prescription after stroke and identify any long-term benefits.
