Understanding the effect of each muscle activation on the joint rotation is important for biomechanicst, clinicians, physical therapists, and sports coaches. However, it is difficult to intuitively understand each muscle action on the joint rotation, because a muscle action changes in a complicated manner depending on two aspects of human body structure i.e., 1) musculoskeletal geometry and 2) inertial property of the kinematic chain distal to the focused joint. Since textbooks of the anatomy describe only the effect of the muscle geometry, this study develops an interactive graphic tool that could help to understand each muscle action considering both the muscle geometry and inertial property. This study will show that the anterior deltoid muscle can act as the external rotator, although textbooks of the anatomy describe that the muscle act as the flexor, abductor, adductor, and internal rotator.
