To evaluate the scapulo-humeral rhythm of patients with a clinical condition, not only a quantitative evaluation (range of motion) but also a qualitative evaluation (a structural method that measures scapular upward rotation) is required. This study investigated the effectiveness of an analysis that assessed the scapular-girdle dynamics, in which the direction and translation of the coordinates were analyzed using electromyograms of the scapular muscle activities of the elevated upper limb. Scapula upward rotation did not show a difference during shoulder flexion and abduction. The difference between shoulder flexion and abduction was more prominent when we used a structural method that measured scapular upward rotation including clavicle movement. When considering a structural method that measures scapular upward rotation during shoulder flexion and abduction, the function of the scapular muscle must be taken into account, since it may worsen and develop into a clinical condition. The direction of gravity that acts on the shoulder joint changes when the shoulder position changes during exercise. Therefore, a change is observed in the mechanical energy of the shoulder. It should be possible to design a therapeutic-exercise program that includes exercise positions that improve the function of the scapular and shoulder muscles to treat shoulder disorders.
