Evaluation of Upper Limb Muscle Activation Using Musculoskeletal Model with Wearable Assistive Device

Figure 4

Subject wearing an assistive device performing maximum shoulder flexion and extension. This movement acquires the subject to flex the elbow to the close to 90 deg, and then the upper arm will be brought to the upper limit of the arm’s reachable motion and then return to the initial position. Data (b) shows measured elbow flexion angle, shoulder flexion angle, and tension force versus time.
