Trunk function during arm elevation movement

Abstract

Arm elevation movement is used in daily living. There are many reports about the functions of the muscle activities and biomechanics of the shoulder joint. However, there are few reports about trunk function during arm elevation movement. We have performed physical therapy for patients without shoulder joint problems who had difficulty with arm elevation movement. We think trunk function is important in arm elevation movement. Therefore, we examined trunk function during arm elevation movement, and describe it in this report.
