Powered wheelchair is the necessary equipment to support outdoor activities of disable people. In daily living, the drive over various level differences and rough road repeatedly may be caused bad postural change that is impossible of self-controlled balance. In this reason, rehabilitation used powered wheelchair for severely disabled people, especially who are essential to operate it by chin, is trained to be large tilt angle of seat during the drive over them. This study examined postural stability on seat and efficacy of tilt angle of it during level differences. Five subjects with tetraplegia using chin-controller participated in this examination. As a result, it was confirmed to decrease magnitude of postural sway on the sagital plane with increasing tilt angle. In addition, it was affected by not only tilt angle but also its approach speed to level difference.
