Abstract

This study described the operation of the myoelectrically controlled robotic system designed to assist wrist movement in a horizontal plane for patients after stroke. Electromyographic (EMG) signals from flexor carpi radialis (FCR), extensor carpi radialis (ECR) detecting subject's intention are used to control the mechanical assistance from the robotic system either to assist wrist flexion and wrist extension, This study had recruited five subjects after stroke. The results revealed that the range of motion (ROM) in the five subjects increased with the assistance of the myoelectrically controlled robotic system. The amplitude of agonist EMG signal decreased with the increase of assistance, which might reflect less effort was needed for the subject to perform the movement. This study demonstrates that it is feasible to apply myoelectrically controlled robotic system to provide substantial external torque to the affected wrist joint for subjects after stroke. Its therapeutic effect will be further investigated during stroke rehabilitation.
