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 …

Whole body vibration (WBV) has acute effects on postural control strategy. The degree of impact depends on the amplitude, frequency, and duration of WBV, and the difficult level of balance task as well as the reliability of sensory information to the individual [1, 2, 3]. Healthy young adults can return to the baseline level of postural sway for a simple balance task within 20 minutes after repeated exposure to WBV [4]. Little is known about the acute and residual effects of WBV on the center-of-mass (COM) movement after a single bout of WBV. This study aimed to understand the COM …
