Significant potential exists for mechatronic devices to improve assessment and treatment of individuals with a movement disability following stroke, traumatic brain injury, or cerebral palsy. We report the use of a mechatronic device for evaluation of the arm after chronic brain injury. We performed a series of experiments with the device in order to identify the relative contribution of three different motor impairments to decreased active range of motion of reaching in five brain-injured subjects. Our findings were that passive tissue restraint and agonist weakness, rather than antagonist restraint, were the most common contributors to decreased active range of motion. These results demonstrate the feasibility of objective assessment of functional movement using a mechatronic device, and could provide the basis for improved, individualized treatment planning and monitoring following brain injury.
