Then present recommend of therapy treatment is based on findings. This research is divided into two parts. First, to find out effective shoulder movement direction that may be more effective therapy, emphasized on influence of range of shoulder motion. Second, indicate and estimate movement direction when and how shoulder muscles are used. Therefore, those findings in this paper can help us to avoid further hurts and can improve effect of therapy treatment. The experiment includes 5 groups, 50 normal people with healthy shoulders, are observed, aging from 40 to 60. There are 5 different kinds of shoulder movement direction, including shoulder abduction, forward flexion, backward extension, shoulder external rotation, and shoulder internal rotation. Based on individual group, patients would do one assigned shoulder movement direction, 3 to 5 minutes a time, twice a day, and total 4 weeks. Results indicate that there is interaction of treatment between shoulder abduction and forward flexion. In other words, when shoulder abduction is effective, range of motion of shoulder abduction increases, as well as range of motion of forward flexion. Doing flexion also increases range of motion of forward flexion and shoulder abduction. On the other hand, there is also interactive rotation and shoulder internal rotation. The results of EMG indicate that not only fewer muscles are used, but also smaller powers are released, because observed estimated IEMG become smaller. Therefore, muscles become stronger.
