Self-training to improve UE function at the chronic stage post-stroke: a pilot randomized controlled trial.

AbstractBackground and purpose: On-going practice and use of the weaker upper extremity (UE) are important for maintaining and improving function in individuals with chronic stroke. The effectiveness of two self-training programs for UE function and daily-use was compared.Methods: In this pilot, single-blinded clinical trial, individuals with chronic stroke were randomized to video-games or traditional self-training (1-hour/day, 6-times/week, 5 weeks). Assessments were performed pre-intervention (an average of two assessments), post-intervention, and at 4-week follow-up. The primary outcome was the functional ability of the upper extremity [The Action Research Arm Test (ARAT)]. Secondary measures were the daily use of the upper extremity [Motor Activity Log (MAL)] and manual dexterity (Box and Block Test). Repeated measures ANOVA was used to test the effectiveness and estimate effect sizes.Results: Twenty-four of the 142 participants screened by phone were randomized to video-games [N = 13, mean (SD) age ...
