Robotic Training for Stroke Neurorehabilitation

The overall goal is to further develop a robotic exoskeleton for neurorehabilitation of arm function after stroke. The investigators previously developed a novel training protocol that combined the ARMin and HandSOME exoskeletons. This is one of only a few arm exoskeletons that allow coordinated whole limb training in reach and grasp tasks with both virtual and real objects. However, the robot has a very large inertia and friction, and only gross grasp patterns are available. In development work, the investigators will significantly modify the AMRin and HandSOME to deliver a state-of-the-art lightweight robotic exoskeleton capable of retraining a wide range of functional activities. In the subsequent testing phase, a clinical trial will examine the effects of robotic training in chronic stroke subjects.
