Abstract: This thesis presents a custom virtual reality (VR) rehabilitation system designed for upper extremity (UE) motor function, composed of three virtual activities of daily living (ADLs) and an Oculus Rift and Touch System. A custom biomechanical model designed to estimate UE joint angles and the Oculus Touch pose was also presented. Six healthy participants completed 10 repetitions of each VR task while the VR system and an optoelectronic motion capture system collected kinematic data simultaneously. The VR system successfully prompted consistent motion, and motion primarily in the designed spatial directions for each task. Varying linear relationships existed between the measured Oculus Touch pose and UE joints among tasks, however, the Oculus Touch’s measured position in each task’s primary direction was significantly related to elevation angle and elbow flexion. Results indicate that a task-specific approach be applied when developing constraints to simplify model estimation of UE joints during dynamic motion.
