Background and Purpose— Although there is strong evidence on the beneficial effects of virtual reality (VR)-based rehabilitation, it not yet well understood how different aspects these systems affect recovery. Consequently, we do exactly know what features VR neurorehabilitation are decisive in conveying their effects. Methods— To specifically address this issue, developed 3 configurations same VR-based rehabilitation system, Rehabilitation Gaming System, using interface technologies: vision-based tracking, haptics, a passive exoskeleton. Forty-four patients with chronic stroke were randomly allocated to one used system for 35 minutes day 5 days week during 4 weeks. Results— Our results revealed significant within-subject improvements at most standard clinical evaluation scales all groups. Specifically observe that training modulated by use/nonuse compensatory movement strategies specific sensorimotor contingencies presented user, is, visual feedback versus combined haptic feedback. Conclusions— findings suggest such as System treatment depend used. These have implications design future aim maximizing functional outcomes retention. Clinical Trial Registration— This trial was registered because small study evaluates feasibility prototype devices.
