Creating a Reachable Workspace Model With 3D Motion Capture to Track Adult Brachial Plexus Injury Recovery: A Representative Case Report

We describe the treatment of a patient recovering after reconstruction surgery for brachial plexus injury (BPI), which causes damage to the nerves of the arm. We used 3D motion capture to create a 3D "map" of the patient's reachable workspace-that is, how far the patient could reach within his own environment as a measure of how well his arm functioned-and tracked changes over a 2-year period. We also describe the patient's self-reported outcomes and compare them to the workspace measurement.
