Additional Exercises Improve Trunk Performance After Stroke: A Pilot Randomized Controlled Trial:

Background. Sitting balance and the ability to perform selective trunk movements are important predictors of functional outcome after stroke. However, studies evaluating the effect of exercises aimed at improving trunk performance are sparse. Objective. To examine the effect of additional trunk exercises on trunk performance after stroke. Methods. An assessor-blinded randomized controlled trial was carried out at an inpatient stroke rehabilitation center. In total 33 participants were assigned to an experimental group (n = 17) or a control group (n = 16). In addition to conventional therapy, the experimental group received 10 hours of individual and supervised trunk exercises; 30 minutes, 4 times a week, for 5 weeks. Trunk performance was evaluated by the Trunk Impairment Scale (TIS) and its subscales of static and dynamic sitting balance and coordination. A general linear repeated measures model was used to analyze the results of our study. Results. No significant differences were found pretreatment betw...
