In this study activity of muscles was examined to determine the effect of shoulder and arm muscle wearing a shoulder abduction brace during grip exercise using 5 grade Ratings of Perceived Exertion(RPE). 11 female healthy adults over 19 years of age volunteered were assigned and subjects measured the muscle activity with dominant arm through EMG. The muscle activity were analyzed after performing grip exercise in Trapezius, Anterior deltiod, Middle deltiod, Posterior deltoid, Triceps, Biceps, Flexor carpi ulnaris, Extensor carpi radialis. The results show that activity of muscles did not differences the triceps, biceps and flexor carpi ulnaris but the Trapezius, Anterior deltoid, Middle deltiod, posterior deltoid and Extensor carpi radialis was significantly increased the muscles activity. This study found that RPE grades was differences according to activity of the muscles. The data suggest that the early rehabilitation might be prevented the sarcopenia and muscular atrophy when the subjects were performed the exercise of minimum grade that exercise intensity muscle activity to fix a period. In conclusion, the everyday life will be effective to return the recovery of rapid time.
