Model simulation of FES for the treatment of shoulder subluxation

Recently, functional electrical stimulation (FES) has been applied for the treatment of the shoulder subluxation. The purpose of this study is to design a musculo-skeletal dynamic model for hemiplegic shoulder subluxation with which can perform FES effectively as well as the simulation of shoulder motion by FES. We installed the muscle models into the skeletal model. In this model, scapula and clavicle are fixed, and only gleno-humeral joint can move. We set up muscle activation, and stimulate deltoideus and supuraspinatus. As a result of simulation, we can confirm the reduction of shoulder subluxation.
