From previous experimentation with the MyHand device, the investigators have determined that the device can improve the grasping ability of stroke patients. The investigators now aim to make the controls more intuitive and accurate for the users, to enable subjects to grasp a wider array of objects, to make the donning and doffing of the device easier, and to continue to assess the MyHand as it helps subjects in functional tasks.
