Loss of arm and hand movement is common after stroke, and recovery is often incomplete. By activating the muscles with electrical current, useful arm and hand movements can be produced. An implanted electrical stimulation system (called a neuroprosthesis) may be an effective permanent assistive device to enable stroke patients to move and use their weak arm and hand again for daily tasks. This study presents the first stroke survivor to receive an implanted stimulator with the capability of activating 12 muscles for assisting arm and hand function. The participant experienced gains on several measures of arm and hand movement and function, but the improvement was limited by muscle tone and fatigue.
