    Input: Background and Purpose — A new gait training strategy for patients with stroke seeks to increase walking speed through treadmill training . This study compares the effects of structured speed-dependent treadmill training ( STT ) ( with the use of an interval paradigm to increase the treadmill speed stepwise according to principles of sport physiology ) with limited progressive treadmill training ( LTT ) and conventional gait training ( CGT ) on clinical outcome measures for patients with hemiparesis . Methods — Sixty ambulatory poststroke patients were each r and omly selected to receive 1 of the 3 different gait therapies : 20 subjects were treated with STT , 20 subjects were trained to walk on a treadmill with a 20 % increase of belt speed over the treatment period ( LTT ) , and 20 subjects were treated with CGT . Treatment outcomes were assessed on the basis of overground walking speed , cadence , stride length , and Functional Ambulation Category scores . Results — After a 4-week training period , the STT group scored significantly higher than the LTT and CGT groups for overground walking speed ( STT versus LTT , P < 0.001 ; STT versus CGT , P < 0.001 ) , cadence ( STT versus LTT , P = 0.007 ; STT versus CGT , P < 0.001 ) , stride length ( STT versus LTT , P < 0.001 ; STT versus CGT , P < 0.001 ) , and Functional Ambulation Category scores ( STT versus LTT , P = 0.007 ; STT versus CGT , P < 0.001 ) . Conclusions — Structured STT in poststroke patients result ed in better walking abilities than LTT or CGT . This gait training strategy provides a dynamic and integrative approach for the treatment of gait dysfunction after stroke Background and Purpose — This study compared the psychometric properties of 3 clinical balance measures , the  Berg Balance Scale ( BBS ) , the Balance subscale of the Fugl-Meyer test ( FM-B ) , and the Postural Assessment Scale for Stroke Patients ( PASS ) , in stroke patients with a broad range of neurological and functional impairment from the acute stage up to 180 days after onset . Methods — One hundred twenty-three stroke patients were followed up prospect ively with the 3 balance measures 14 , 30 , 90 , and 180 days after stroke onset ( DAS ) . Reliability ( interrater reliability and internal consistency ) and validity ( concurrent validity , convergent validity , and predictive validity ) of each measure were examined . A comparison of the responsiveness of each of the 3 measures was made on the basis of the entire group of patients and 3 separate groups classified by degree of neurological severity . Results — The FM-B and BBS showed a significant floor or ceiling effect at some DAS points , whereas the PASS did not show these effects . The BBS , FM-B , and PASS all had good reliability and validity for patients at different recovery stages after stroke . The results of effect size demonstrated fair to good responsiveness of all 3 measures within the first 90 DAS but , as expected , only a low level of responsiveness at 90 to 180 DAS . The PASS was more responsive to changes in severe stroke patients at the earliest period after stroke onset , 14 to 30 DAS . Conclusions — All 3 measures tested showed very acceptable levels of reliability , validity , and responsiveness for both clinicians and research ers . The PASS showed slightly better psychometric characteristics than the other 2 measures Background Increased therapy has been linked to improvements in functional ability of people with stroke . Aim To determine the effectiveness of two alternative models of increased physiotherapy service delivery ( seven-day week therapy or group circuit class therapy five days a week ) to usual care . Method Three-armed r and omized controlled trial with blinded assessment of outcome . People admitted with a diagnosis of stroke , previously independently ambulant and with a moderate level of disability were recruited .  ‘ Usual care ’ was individual physiotherapy provided five-days a week . Seven-day week therapy was usual care physiotherapy provided seven-days a week . Participants in the circuit class therapy arm of the trial received physiotherapy in group circuit classes in two 90-min sessions , five-days a week . Primary outcome was distance walked on the six-minute walk test at four-weeks post-r and omization . Results Two hundred eighty-three participants were r and omized ; primary outcome data were available for 259 ( 92 % ) . In the seven-day arm participants received an additional three hours of physiotherapy and thosein the circuit class armanadditional 22 h. There were no significant between-group differences at four-weeks in walking distance ( P = 0·72 ) . Length of stay was shorter for seven-day ( mean difference −2·9 days , 95 % confidence interval −17·9 to 12·0 ) and circuit class participants ( mean difference −9·2 days , 95 % confidence interval −24·2 to 5·8 ) compared to usual care , but this was not significant . Conclusions Both seven-day therapy and group circuit class therapy increased physiotherapy time , but walking outcomes were equivalent to usual care OBJECTIVES To identify the most responsive method of measuring gait speed , to estimate the responsiveness of other outcome measures , and to determine whether gait speed predicts discharge destination in acute stroke . DESIGN A prospect i ve cohort study . SETTING Five acute-care hospitals . PATIENTS Fifty subjects with residual gait deficits after a first-time stroke . INTERVENTIONS Five- ( 5mWT ) and 10-meter walk tests ( 10mWT ) at comfortable and maximum speeds , with 2 evaluations conducted an average + /- st and ard deviation ( SD ) of 8 + /- 3 and 38 + /- 5 days poststroke . MAIN OUTCOME MEASURE St and ardized response mean ( SRM = mean change/SD of change ) was used to estimate responsiveness for each walk test , the Berg Balance Scale , the Barthel Index , the Stroke Rehabilitation Assessment of Movement ( STREAM ) , and the Timed Up and Go ( TUG ) . RESULTS The SRMs were 1.22 and 1.00 for the 5mWT , and .92 and .83 for the 10mWT performed at a comfortable and maximum pace , respectively . The SRMs for the Berg Balance Scale , the Barthel Index , the STREAM , and the TUG were 1.04,.99,.89 , and .73 , respectively . The probability of discharge to a rehabilitation center for persons walking at < or = 0.3 m/s or > 0.6 m/s at the first evaluation was.95 and .22 , respectively . CONCLUSIONS The 5mWT at a comfortable pace is recommended as the measure of choice for clinicians and research ers who need to detect longitudinal change in walking disability in the first 5 weeks poststroke Background and Purpose — One way that stroke units may improve outcome is by reducing complications of immobility through early mobilization ; however , this intervention needs testing . The purpose of this study was to determine the physical activity patterns of stroke patients managed within acute stroke units as a first step in developing an early mobilization protocol . Methods — We recruited 64 patients within 14 days after stroke from 5 metropolitan stroke units and observed them for 2 consecutive days at 10-minute intervals between the hours of 8 am and 5 pm . At each observation , we ascertained physical activity , location , and other person(s ) present . Therapists recorded therapy details . Results — The 58 patients who completed the study had a mean age of 71.3 years . Stroke severity ranged from mild ( National Institutes of Health Stroke Scale score , 1 ) to severe ( score , 27 ) , and mean time after stroke at observation was 5.6 days ( range , 0 to 13 days ) . Only 9 patients were restricted to bed . During the therapeutic day , patients spent > 50 % resting in bed , 28 % sitting out of bed , and only 13 % engaged in activities with the potential to prevent complications and improve recovery of mobility . Patients were alone > 60 % of the time . Conclusions — This is the first multicenter study of physical activity early after stroke . We believe the next step is to conduct a r and omized controlled trial to evaluate the effect of increased levels of  physical activity  early after stroke compared with current st and ards of care QUESTION Do people with stroke spend more time in active task practice during circuit class therapy sessions versus individual physiotherapy sessions ? Do people with stroke practise different tasks during circuit class therapy sessions versus individual physiotherapy sessions ? DESIGN Prospect i ve , observational study . PARTICIPANTS Twenty-nine people with stroke in inpatient rehabilitation setting s. INTERVENTIONS Individual therapy sessions and circuit class therapy sessions provided within a larger r and omised controlled trial . OUTCOME MEASURES Seventy-nine therapy sessions were video-recorded and the footage was analysed for time spent engaged in various categories of activity . In a sub sample of 28 videos , the number of steps taken by people with stroke per therapy session was counted . RESULTS Circuit class therapy sessions were of a longer duration ( mean difference 38.0minutes , 95 % CI 29.9 to 46.1 ) , and participants spent more time engaged in active task practice ( mean difference 23.8minutes , 95 % CI 16.1 to 31.4 ) compared with individual sessions . A greater percentage of time in circuit class therapy sessions was spent practising tasks in sitting ( mean difference 5.3 % , 95 % CI 2.4 to 8.2 ) and in sit-to-st and practice ( mean difference 2.7 % , 95 % CI 1.4 to 4.1 ) , and a lower percentage of time in walking practice ( mean difference 19.1 % , 95 % CI 10.0 to 28.1 ) compared with individual sessions . PARTICIPANTS took an average of 371 steps ( SD 418 ) during therapy sessions and this did not differ significantly between group and individual sessions . CONCLUSION People with stroke spent more time in active task practice , but a similar amount of time in walking practice when physiotherapy was offered in circuit class therapy sessions versus individual therapy sessions . There is a need for effective strategies to increase the amount of walking practice during physiotherapy sessions for people after stroke Objective : To investigate the feasibility and the effects on gait of a high intensity task-oriented training , incorporating a high cardiovascular workload and large number of repetitions , in patients with subacute stroke , when compared to a low intensity physiotherapy-programme . Design and subjects : R and omized controlled clinical trial : Forty-four patients with stroke were recruited at 2 to 8 weeks after stroke onset . Measures : Maximal gait speed assessed with the 10-metre timed walking test ( 10MTWT ) , walking capacity assessed with the six-minute walk test ( 6MWT ) . Control of st and ing balance assessed with the Berg Balance Scale and the Functional Reach test . Group differences were analysed using a Mann — Whitney U-test . Results : Between-group analysis showed a statistically significant difference in favour of the high intensity task-oriented training in performance on the 10MTWT ( Z = -2.13 , P = 0.03 ) and the 6MWT ( Z = -2.26 , P = 0.02 ) . No between-group difference were found for the Berg Balance Scale ( Z = —0.07 , P = 0.45 ) and the Functional Reach test ( Z = —0.21 , P = 0.84 ) . Conclusion : A high-intensity task-oriented training programme design ed to improve hemiplegic gait and physical fitness was feasible in the present study and the effectiveness exceeds a low intensity physiotherapy-programme in terms of gait speed and walking capacity in patients with subacute stroke . In a future study , it seems appropriate to additionally use measures to evaluate physical fitness and energy expenditure while walking OBJECTIVE To evaluate the effect of an 8-week , water-based exercise program ( experimental group ) with that of an upper-extremity function program ( control group ) to increase cardiovascular fitness within a community setting for people with stroke . DESIGN Single-blind r and omized controlled trial . SETTING Public community center . PARTICIPANTS A volunteer sample of 12 community-dwelling people with stroke with mild to moderate residual motor deficits . INTERVENTION Study subjects participated in group exercise programs for 1 hour , 3 times a week for 8 weeks . The experimental group exercised in chest-deep water at targeted heart rates . The control group performed arm and h and exercises while sitting . Main outcome measures The primary outcome measure was cardiovascular fitness ( V(O2)max ) . Secondary measures were maximal workload , muscle strength , gait speed , and the Berg Balance Scale score . RESULTS The experimental group attained significant improvements over the control group in cardiovascular fitness , maximal workload , gait speed , and paretic lower-extremity muscle strength . The relatively short program ( 8 wk ) of water-based exercise result ed in a 22 % improvement in cardiovascular fitness in a small group of people with stroke who had relatively high function . CONCLUSIONS A water-based exercise program undertaken as a group program may be an effective way to promote fitness in people with stroke Background . Exercise interventions can enhance mobility after stroke as well as prevent falls in elderly persons . Objective . Investigate whether an exercise intervention can enhance mobility , prevent falls , and increase physical activity among community-dwelling people after stroke . Method . A r and omized trial with blinding of physical outcome assessment was conducted through local stroke clubs . Both groups , on average 5.9 years poststroke , received exercise classes , advice , and a home program for 12 months . The experimental group ( EG ) program ( n = 76 ) aim ed to improve walking , prevent falls and increase physical activity . The control group ( CG ) program ( n = 75 ) aim ed to improve upper-limb and cognitive functions . The primary outcomes were walking capacity , walking speed measured before
