Our objective is to evaluate the therapeutic efficacy of robot-aided exercise for recovery of upper limb motor function following stroke. We have developed a robotic system which applies forces to the paretic limb during passive and active-assisted movements. A clinical trial is underway which compares robot-aided exercise with conventional NeuroDevelopmental Therapy (NDT). Preliminary data suggests robot-aided exercise has therapeutic benefits. Subjects who have completed a two month training protocol of robot-aided exercises have demonstrated improvements in active-constrained training tasks, free-reach kinematics, and the Fugl-Meyer assessment of motor function. Integration of robot-aided therapy into clinical exercise programs would allow repetitive, time-intensive exercises to be performed without one-on-one attention from a therapist.
