Muscle activity of shoulder and scapular surrounding muscles during various push-up plus - Muscle activity of shoulder and scapular surrounding muscles during various push-up plus

In the result of Muscle activity comparison by the posture, in the EPUP posture, the SA muscle activity and PM/SA muscle activity ratio was significantly increased. In the SPUP posture, the SA muscle activity was greater than KPUP posture. On the other hand, PM muscle activity was significantly smaller than EPUP posture. Meanwhile, AD muscle activity was significantly increased than KPUP posture. In the KPUP posture, the SA muscle activity was significantly smaller than other 2 postures. Finding of this study we suggest that PUP exercise beginning with KPUP posture progressing to the SPUP posture, finally the EPUP posture with SW hand position. This progression may assist the particular activation of SA muscle without compensatory activation of PM muscle for patients with shoulder disorder in rehabilitation by gradually.
