Virtual reality environments (VEs) are new tools to improve functional recovery in stroke survivors. Elements essential to maximize motor learning, can be optimized in VEs. Study objectives were: (a) to determine whether training in VE with enhanced feedback about movement patterns, leads to greater gains in arm movement quality, motor performance and decreased compensation compared to training in a similarly designed Physical environment (PE); (b) to estimate whether impairments in cognitive functioning affected the changes observed after training. Twelve stroke survivors practiced 72 pointing movements in VE or PE for 10 sessions with enhanced feedback. Kinematic analysis of pointing task, evaluations of arm impairment and function were carried out pre-post training. After training, VE group had increased shoulder flexion (p<0.05), increased shoulder horizontal adduction and decreased compensation, compared to PE group. Use of feedback correlated with fewer deficits in cognitive functioning. Training in VEs may lead to greater gains in movement quality.
