Assessment of Motor Function in Complex Regional Pain Syndrome With Virtual Reality-based Mirror Visual Feedback: A Pilot Case Study
Method: We compared reaching movements of the wrist and elbow during the VR-MVF treatment task. A personal VRMVF system was used for collecting data. Reaching movements were defined as movements from 2 seconds before the grasp of the virtual object to the time at which the object was grasped.
Result: The results showed that healthy participants performed reaching movements with their hand. On the other hand, the patients with CRPS tended to perform reaching movements by moving their elbow instead of their hand. In addition, the results showed that the increase in trajectory length of the patients’ hand relative to their elbow may relate to pain reduction.
Conclusion: In accordance with these results, we suggest that focusing on the movements of the hand and the elbow may be useful for understanding the condition of these patients, and that hand and elbow movements may be used as indices.

NBE is the official journal of the Institute of Complex Medical Engineering (ICME). The journal promotes the best interdisciplinary research in neuroscience and biomedical engineering. NBE welcomes contributions in any domain of neural and biomedical engineering ranging in content from practical/clinical applications through experimental science, technological developments to quantitative and/or statistical methodology discussions. NBE publishes the following article types: original articles, research reviews, and book reviews.
The goal of this journal is to establish a new forum for this interdisciplinary field so neuroscientists and biomedical engineers can publish their research works in one periodical. NBE is devoted to bridge the gap between Neuroscience and Biomedical Engineering , and to foster the mutual understanding in both fields.
