摘要：This paper presents the pilot study of wobble seat on trunk muscles activity and kinematics. For this study the wobble board and wobble board on bearing surface were used to compare muscles activity and body segments kinematics on these different platforms. Two pelvic motions were performed: anterior – posterior and side to side. During this study the electromyography (sEMG) of trunk muscles and motion capture analysis were done. Results showed that sitting on wobble board placed on bearing surface leaded to increment of the activity of deep muscles with smaller pelvic movement in anterior – posterior pelvic motion.
