Development of an MR safe reach and grasp movement evaluation system to study brain activation patterns after stroke.

An MR safe apparatus is important for the for monitoring of tasks in the magnetic resonance (MR) environment. This paper describes the development of an MR safe movement evaluation system to measure the hand grasp and elbow flexion/extension movements. The system will be used to monitor motor performance in the fMRI environment and assess functional and motor impairment level pre and post robot-assisted therapy.
