Several causes may result in motor impairment that affects or causes the motions disabilities of the upper limb, among them are spinal cord injury, stroke and wrist drop. Various causes result in the above conditions, so the need for rehabilitation therapy was of most importance. Generally, the researchers interested in and focus on the designing and construction of the lower limb systems for rehabilitation purposes rather than that for upper limbs. This paper focuses on designing and construction of a low cost, two degree freedom (DOF) (including flexion/extension and adduction/abduction), a portable robotic exoskeleton for wrist rehabilitation which designed and constructed with 3D printer technique using polylactic acid (PLA) material and Solid Works software program and controlled with EMG myoware and gyroscope sensors. A significant accurate range of motion and velocity is provided. Moreover, the proposed design of the robotic exoskeleton is comfort, lightweight, simple and economic as well.
