Center Of Mass Control And Multi-Segment Coordination In Children During And After Whole-Body Vibration, Huaqing Liang, Jianhua Wu

Physical Therapy Faculty Research

Maintaining upright posture under external perturbations requires the coordination between the nervous system and the musculoskeletal system, and it is a milestone of motor development in early childhood. Whole-body vibration (WBV) has acute effect on postural control and muscular activation during standing, resulting in an increased sway velocity and sway area of center-of-mass (COM), and the residual effect usually vanishes within 20 minutes after the vibration exposure. In quiet standing, a human body can be considered as a multi-segment linked system, and an uncontrolled manifold (UCM) approach has been used to examine how this multi-joint motor redundancy is utilized to …
