Description

The standard for evaluating basic movements is hard to be systematized. In the present study, paying attention to a rising motion among those basic movements, we examined the effect of location of the shoulder joint on the rising motion. Subjects were 10 healthy males (average age: 21.3 ± 1.77 years, average height: 171.3 ± 3.97 cm, average weight: 66.5 ± 10.4 kg). For comparison with patients who had experienced cerebral vascular accident, two female subjects also participated in the study. The surface electrodes were placed on teres major muscle, infraspinous muscle, rhomboid muscle, and straight muscle of abdomen, and the activities of periarticular muscle of shoulder joint and trunk flexors were measured. The measurements were made in rising motions both with the shoulder joint abducted at a specified degree and with the normal position of shoulder joint, and the results were compared. The abduction angles of shoulder joint were 10, 30, 60, 90 and 120 degrees, and data were statistically analyzed using the Spearman's order correlation test followed by the χ2-test. In healthy male subjects, as for relationship between specified degree and activities of periarticular muscle, muscular activities of rhomboid muscle and infraspinous muscle were found biased(p<0.05), and in female subjects muscular activities tended to be lower in normal position of shoulder joint than in order positions. In the patients, each muscle tended to show a specific pattern of activity, which suggests that muscle activities are affected by the abduction degree of shoulder joint in the starting posture.
