Analysis of the movement from the sitting position to the supine position

Abstract

Visual observation and electromyographic evaluation of the movement from the sitting position to the supine position were performed. In the movement from the sitting position to the side-lying position, the forearm of the upper limb supports the lateral bending of the trunk after elevation of the pelvis. The pelvis is elevated by the muscle activity of the oblique muscle on the opposite side, which is important.
