About this trial
The purpose of this study is to evaluate the safety, feasibility, and efficacy of an exoskeletal network of passive, multi-joint springs for forearm supination. Also known as the forearm ExoNET, the device is a passive, robotic device that will properly assist forearm supination in the post-stroke adult population.
