Development of Myoelectric Prostheses with Elbow Joint

The purpose of this study is to develop a myoelectric prosthesis that can move the elbow joint arbitrarily. The elbow joint angle intended by the user is estimated from the myoelectric potential, and the elbow joint prosthesis follows the angle to achieve voluntary and responsiveness. The upper limb musculoskeletal model is used for this estimation. In the musculoskeletal model, the myoelectric potential of the upper arm during elbow joint movement is input and the elbow joint angle is output, and the effectiveness of the elbow joint angle estimation method using this model is experimentally verified. In order to verify the effectiveness of the actual machine, a motor-driven elbow joint mechanism is manufactured and implemented.
