Development of 2-DOF robotic exoskeleton for upper limb rehabilitation after stroke

This paper presents the development of 2-DOF robotic exoskeleton for upper limb rehabilitation after stroke. We focused on the powered exoskeleton which consists of a cable-driven mechanism actuated by brushless motors. Strain gages measured torques which loaded elbow flexion/extension and wrist pronation/supination axes. To begin each trials, sEMG (surface Electromyography) was used to detect the voluntary movements of subjects.
