Visualization of virtual reality neurological motor rehabilitation of the upper limb — A systematic review

摘要

Most virtual rehabilitation environments rely on visual feedback. However, little is known on the optimum characteristics of these feedbacks. Here, we present first results of a systematic literature review to assess and compare visual feedback types in virtual reality (VR) based neurological motor rehabilitation of the upper limb. Overall we identified 104 relevant publications. Within these some applied multiple visual feedback types. We found six main visualization groups: Avatar Feedback (N=52), Augmented Reality Feedback (N=16), Abstract Feedback (N=40), Tracking Feedback (N=13), Performance Evaluation Feedback (N=2), and Combined Feedback (N=7). However, there is insufficient evidence for the choice of a specific visual feedback in relation to motor outcome. Thus, further research is necessary.
