Subjects will be enrolled in the study if they meet eligibility criteria assessed at a screening visit. Once enrolled subjects will be custom fit with a MyoPro Motion-G elbow-wrist-hand orthosis following standard clinical procedures. This process requires up to three visits to cast, trial fit and deliver the orthosis. Subjects will then participate in a standard-of-care motor learning based therapy protocol in conjunction with the PERL ("Push Eat Reach Lift") training program recommended by Myomo, which consists of a 9 week, 18 session training plan. Every second week, there will be one session that will combine therapy/training and outcomes evaluation.
