Abstract
[Purpose] The purpose of this study was to investigate the movement of the shoulder girdle and scapula on the rib cage and trunk in lateral tilt sitting. [Subjects and Methods] The angle of the upper and lower trunk, tilt angle of the shoulder girdle, and the angle of scapula rotation on the rib cage in sitting, and sitting with right and left lateral tilt of 15 healthy adults were measured. The measured angles were compared among 3 positions. [Results] In bilateral tilt sitting, contralateral bending of the upper and lower trunk toward the tilted side, and lower rotation of the scapula on the rib cage of the tilted side were observed, but there was no significant difference in the angle of the shoulder girdle. [Conclusion] The angle of the shoulder girdle did not change in lateral tilt sitting because of lateral bending of the upper and lower trunk, and lower rotation of the scapula on the rib cage.
