BACKGROUND AND PURPOSE: A debated subject in @entity64 rehabilitation relates to the best type of training approach for motor recovery. First, we analyzed the effects of repetitive movement practice in 2 feedback conditions (knowledge of results [KR]; knowledge of performance, [KP]) on reacquisition of reaching. Second, we evaluated the impact of @entity73 on motor relearning ability. METHODS: A randomized controlled clinical trial was conducted in Montreal-area rehabilitation centers between 1998 and 2003 with 37 @entity1 with chronic @entity1269 . @entity1 were randomly assigned to 3 groups: (1) KR (n=14) practiced a reaching task involving 75 repetitions per day, 5 days per week for 2 weeks, with 20% KR about movement precision; (2) KP (n=14) trained on the same task and schedule as KR but with faded KP about joint motions; and (3) control (C; n=9) practiced a nonreaching task. Physical (motor impairment, function) and kinematic (movement time, precision, segmentation, variability) variables were assessed before and after (immediately, 1 month) practice. Cognitive functions (memory, attention, mental flexibility, planning) were also evaluated. RESULTS: Kinematic gains in KR (precision) and KP (time, variability) exceeded those in C and depended on memory and @entity51 . In KP, more severely impaired @entity1 made the most clinical gains (>2xC), which were related to memory and planning abilities. CONCLUSIONS: Use of KP during repetitive movement practice resulted in better motor outcomes. @entity64 severity together with @entity73 are important factors for choosing motor rehabilitation interventions after @entity64 .
