    Input: Background Motor imagery ( MI ) when combined with physiotherapy can offer functional benefits after stroke . Two MI integration strategies exist : added and embedded MI . Both approaches were compared when learning a complex motor task ( MT ) : ' Going down , laying on the floor , and getting up again ' . Methods Out patients after first stroke participated in a single-blinded , r and omised controlled trial with MI embedded into physiotherapy ( EG1 ) , MI added to physiotherapy ( EG2 ) , and a control group ( CG ) . All groups participated in six physiotherapy sessions . Primary study outcome was time ( sec ) to perform the motor task at pre and post-intervention . Secondary outcomes : level of help needed , stages of MT-completion , independence , balance , fear of falling ( FOF ) , MI ability . Data were collected four times : twice during one week baseline phase ( BL , T0 ) , following the two week intervention ( T1 ) , after a two week follow-up ( FU ) . Analysis of variance was performed . Results Thirty nine out patients were included ( 12 females , age : 63.4 ± 10 years ; time since stroke : 3.5 ± 2 years ; 29 with an ischemic event ) . All were able to complete the motor task using the st and ardised 7-step procedure and reduced FOF at T0 , T1 , and FU . Times to perform the MT at baseline were 44.2 ± 22s , 64.6 ± 50s , and 118.3 ± 93s for EG1 ( N = 13 ) , EG2 ( N = 12 ) , and CG ( N = 14 ) . All groups showed significant improvement in time to complete the MT ( p < 0.001 ) and degree of help needed to perform the task : minimal assistance to supervision ( CG ) and independent performance ( EG1 + 2 ) . No between group differences were found . Only EG1 demonstrated changes in MI ability over time with the visual indicator increasing from T0 to T1 and decreasing from T1 to FU . The kinaesthetic indicator increased from T1 to FU . Patients indicated to value the MI training and continued using MI for other difficult-to-perform tasks . Conclusions Embedded or added MI training combined with physiotherapy seem to be feasible and benefi-cial to learn the MT with emphasis on getting up independently . Based on their baseline level CG had the highest potential to improve outcomes . A patient study with 35 patients per group could give a conclusive answer of a superior MI integration strategy .Trial Registration Clinical Trials.gov : Background and Purpose — Previous studies have shown that repeated sensory inputs could enhance brain plasticity and cortical motor output . The purpose of this study was to investigate whether combining electrically induced sensory inputs through transcutaneous electrical nerve stimulation ( TENS ) with task-related training ( TRT ) in a home-based program would augment voluntary motor output in chronic stroke survivors better than either treatment alone or no treatment . Methods — Eighty-eight patients with stroke were assigned r and omly to receive a home-based program of ( 1 ) TENS , ( 2 ) TENS+TRT , ( 3 ) placebo TENS+TRT , or ( 4 ) no treatment ( control ) 5 days a week for 4 weeks . Outcome measurements included Composite Spasticity Scale , peak torques generated during maximum isometric voluntary contraction of ankle dorsiflexors and plantarflexors , and gait velocity recorded at baseline , after 2 and 4 weeks of treatment , and 4 weeks after treatment ended . Results — When compared with TENS , the combined TENS+TRT group showed significantly greater improvement in ankle dorsiflexion torque at follow-up and in ankle plantarflexion torque at week 2 and follow-up ( P<0.01 ) . When compared with placebo+TRT , the TENS+TRT group produced earlier and greater reduction of plantarflexor spasticity and improvement in ankle dorsiflexion torque at week 2 ( P<0.01 ) . When compared with all 3 groups , the TENS+TRT group showed significantly greater improvement in gait velocity ( P<0.01 ) . Conclusions — In patients with chronic stroke , 20 sessions of a combined TENS+TRT home-based program decreased plantarflexor spasticity , improved dorsiflexor and plantarflexor strength , and increased gait velocity significantly more than TENS alone , placebo+TRT , or no treatment . Such improvements can even be maintained 4 weeks after treatment ended The purpose of this study was to compare the effects of a task-oriented exercise program with and without altered sensory input on postural stability in subjects with stroke . Sixteen hemiparetic subjects , at least 6 months post-stroke , were r and omly assigned to the experimental or control group , and participated in an 8-week task-oriented exercise program focusing on balance and mobility exercises . Exercises were performed under normal conditions by the control group , and under conditions of vision and surface manipulation by the experimental group . Pre- and post-test assessment s involved the measurement of the center of pressure ( COP ) displacement during double-legged stance and sit-to-st and under four sensory conditions : ( 1 ) eyes open , normal surface ; ( 2 ) eyes open , soft surface ; ( 3 ) eyes closed , normal surface ; and ( 4 ) eyes closed , soft surface , as well as the 10-m walking test . Results showed significant improvements ( P<0.05 ) in COP displacement under sensory conditions ( 1 ) and ( 2 ) for the experimental group only , and limited changes for the sit-to-st and in both groups after training . Significant improvements ( P<0.05 ) were also found in both groups for the walking test . It is concluded that a task-oriented exercise program , assisted by sensory manipulation , is more effective at improving the st and ing balance of stroke subjects than a conventional task-oriented program . Die vorliegende Studie vergleicht die Wirkung eines anforderungsspezifischen Übungsprogramms mit und ohne Sinnesreizänderung auf die posturale Stabilität von Schlaganfallpatienten . Insgesamt 16 Hemiparetiker wurden mindestens sechs Monate nach dem Schlaganfall r and omisiert der Versuchs- oder der Kontrollgruppe zugeordnet , innerhalb derer sie acht Wochen an einem anforderungsspezifischen Programm mit speziellen Gleichgewichts- und Mobilitätsübungen teilnahmen . Die Kontrollgruppe führte die Übungen unter normalen Bedingungen durch , die Versuchsgruppe dagegen unter Manipulation der Aspekte Sicht und Gehflächen . Bei den Bewertungen vor und nach dem Test wurde die Verlagerung des Druckmittelpunkts ( COP ) während der zweibeinigen Haltung und der Aufstehübung anh and von vier Sinneszuständen gemessen : ( 1 ) offene Augen , normale Fläche , ( 2 ) offene Augen , weiche Fläche , ( 3 ) geschlossene Augen , normale Fläche und ( 4 ) geschlossene Augen , weiche Fläche sowie anh and des 10 m Gehtests . Die Ergebnisse wiesen nur bei der Versuchsgruppe bei der COP-Verlagerung unter den Sinneszuständen ( 1 ) und ( 2 ) beachtliche Verbesserungen ( P<0,05 ) auf und bei beiden Gruppen in beschränktem Maß Veränderungen bei der Aufstehübung . Bei beiden Gruppen wurden auch signifikante Verbesserungen ( P<0,05 ) beim Gehtest beobachtet . Daraus schließt sich , dass ein anforderungsspezifisches Übungsprogramm mit begleitender Sinnesmanipulation das Gleichgewicht von Schlaganfallpatienten bei aufrechter Körperhaltung effektiver verbessert als ein herkömmliches anforderungsspezifisches Programm . El propósito de este estudio fue comparar los efectos de un programa de ejercicios dirigidos , con estimulación sensorial alterada o sin ella , sobre la estabilidad postural de sujetos con accidente vascular cerebral . Dieciséis sujetos hemiparéticos que habían sufrido un accidente vascular cerebral hacía al menos 6 meses , fueron distribuidos al azar en dos grupos : uno experimental y uno control . Los mismos participaron durante 8 semanas en un programa de ejercicios dirigidos , el cual se centraba en ejercicios de balance y de movilidad . El grupo control realizó los ejercicios en condiciones normales , mientras que el grupo experimental los realizó en condiciones en que la visión y las superficies fueron alteradas . En las evaluaciones realizadas antes y después de los ejercicios se midió la desviación del centro de presión ( CP ) durante la postura de pie utiliz and o ambas piernas , así como en la postura sentada , listo para ponerse de pie , bajo cuatro condiciones sensoriales deferentes : 1 ) ojos abiertos , superficie normal ;  2  ) ojos abiertos , superficie bl and a ;  3  ) ojos cerrados , superficie normal ;  y  4 ) ojos cerrados , superficie bl and a. Se realizó además la prueba de la marcha de los 10 m. Los result ados mostraron mejoras significativas ( P<0,05 ) en la desviación del CP en ambos grupos durante la prueba de la marcha . Se concluyó que un programa de ejercicios dirigidos , en los que se utilicen manipulaciones sensoriales , es más efectivo que un programa convencional de ejercicios dirigidos para mejorar el balance durante la postura de pie en sujetos con accidente vascular cerebral . Le but de cette étude était de comparer les effets d'un programme d'exercices fonctionnels assistés ou non de stimulations sensorielles sur la stabilité posturale de sujets atteints d'un accident vasculaire cérébral ( AVC ) . Seize sujets hémiparétiques atteints d'un AVC depuis au moins 6 mois et répartis de façon aléatoire au sein du groupe expérimental et du groupe témoin ont participé à un programme d'exercices fonctionnels de huit semaines portant sur des exercices d'équilibre et de mobilité . Les exercices étaient exécutés en situation normale par le groupe témoin et en situation de manipulation de la vision et de la surface de support par le groupe expérimental . Les évaluations pré et post exercices ont été effectuées à l'aide de la mesure du déplacement du centre de pression ( CP ) lors du maintien de la position debout en appui bipodal et du transfert assis-debout selon les quatre conditions sensorielles suivantes : yeux ouverts , surface normale ( 1 ) ; yeux ouverts , surface moelleuse ( 2 ) ; yeux fermés , surface normale ( 3 ) ; yeux fermés , surface moelleuse ( 4 ) . Le test de marche de 10 mètres a aussi été inclus dans l'évaluation . Les résultats ont démontré une amélioration significative ( P<0.05 ) du déplacement du CP dans les conditions 1 et 2 pour le groupe expérimental seulement ainsi que des changements limités pour le transfert assis-debout chez les deux groupes de sujets à la suite de l'entraînement . Une amélioration significative ( P<0.05 ) a été observée au niveau du test de marche chez les deux groupes de sujets . Cette étude a démontré qu'un programme d'exercices fonctionnels assistés de stimulations sensorielles est plus efficace pour l'amélioration du maintien de l'équilibre en position debout chez les sujets atteints d'un AVC qu'un programme d'exercices fonctionnels conventionnnel Objective : To investigate the effect of community-based ambulation training on walking function of patients with post-stroke hemiparesis . Design : R and omized , single-blind , controlled pilot study . Setting : Inpatient rehabilitation hospital . Subjects : Twenty-five subjects were r and omly assigned to either the experimental group or the control group , with 13 and 12 subjects , respectively . Interventions : All subjects received a routine physical therapy . The subjects in the experimental group also received community-based ambulation training , which was performed for an hour , once a day , three times a week for a four-week period . Main measures : Ten-metre walk test , 6-minute walk test , community walk test , walking ability question naire and activities-specific balance confidence scale before and after the intervention . Results : The change values of the 10-m walk test ( 0.21 ± 0.12 m/s versus 0.07 ± 0.10 m/s ) , community walk test ( −13.61 ± 10.31 minutes versus −3.27 ± 11.99 minutes ) , walking ability question naire ( 6.15 ± 3.60 score versus 2.75 ± 2.38 score ) and activities-specific balance confidence scale ( 17.45 ± 11.55 score versus 2.55 ± 10.14 score ) were significantly higher in the experimental group than in the control group ( P < 0.05 ) . At post-test , the 10-m walk test was significantly higher in the experimental group than in the control group ( 0.72 ± 0.24 m/s versus 0.50 ± 0.23 m/s ) ( P < 0.05 ) . In the experimental group , there were significant differences for all variables between pre-test and post-test ( P < 0.01 ) , whereas the subjects of the control group showed a significant difference in only the walking ability question naire ( P < 0.01 ) . Conclusions : The findings demonstrate that community-based ambulation training can be helpful in improving walking ability of patients with post-stroke hemiparesis and may be used as a practical adjunct to routine rehabilitation therapy Background and Purpose — Balance impairment is common after stroke ; modified yoga may be able to improve balance and other important poststroke variables . Scientific- evidence is needed to support such treatment interventions . The purpose of this study was to assess the impact of a yoga-based rehabilitation intervention on balance , balance self-efficacy , fear of falling ( FoF ) , and
