Fig. 3From: Three-dimensional alignment changes of the shoulder girdle between the supine and standing positionsThree-dimensional angular rotations of the clavicle and scapula in the supine and standing positions. a Three-dimensional angular rotations of the clavicle. Compared with the supine position, the clavicle shows significantly less elevation and greater retraction in the standing position. ***P < .001. b Three-dimensional angular rotations of the scapula. Compared with the supine position, the scapula shows less upward rotation, anterior tilting, and internal rotation in the standing position. **P < .01. ***P < .001Back to article page
