In this experimental study, we present the results of user motor responses with and without the use of Tracking Feedback to complete correct movements in Virtual Rehabilitation Therapy. To carry out this study, we used a VRT system for standing balance rehabilitation. We applied it under two different conditions to twenty patients (with and without tracking feedback). We then analyzed their motor responses. By means of this analysis, we have confirmed the importance of Tracking Feedback in the achievement of rehabilitation goals. We also tested the possibility of eliminating the tracking components from the system to lower cost to make the integration of Virtual Rehabilitation systems available to more patients. Our results indicate that is currently not feasible.
