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

Figure 5

Subject wearing an assistive device performing maximum shoulder flexion and extension to the initial position. The arm’s initial position was kept in front of the inner side of the frontal body of the subject. The elbow was flexed to the maximum and returned to the initial position. Data (b) shows measured elbow flexion angle, shoulder flexion angle, and tension force versus time.
