Motor impairments following an upper motor lesion such as stroke include weakness, loss of motor control, and fatigability, as well as characteristics associated with increased levels of involuntary activity: spasticity, increased tendon reflexes, clonus associated reactions, spasms, and coactivation during movement. Subsequent to the initial insult, limb movement may be impaired by mechanical changes, including shortening and increased stiffness of muscles and soft tissue around joints leading to contracture. These combined impairments may affect the individuals ability to move effectively and perofrm the functional tasks. Imporved understanding of patients' specific impairment may aid in optimizing individualized theraputic interventions, and in assessing progress in rehabilitation. The current work presents an experimental rig that aims to measure patients ability to track a target by moving their wrist, and some of the first results on assessing tracking performance and co-activation of flexor and extensor muscles.
