Stair negotiation provides an important yet different paradigm to study environment navigation. As one has constantly move himself up while adjusting step length and foot placement due to the stair constraints, this paradigm is ideal to study motor strategy and adaptation in children with and without disabilities. Down syndrome (DS) is the most common genetic condition and causes significant delays in motor and cognitive development. Children with DS show poor postural control and less efficient gait patterns. When negotiating obstacles, they often select a more conservative strategy (i.e. crawling instead of walking). This study aimed to examine motor strategy and …

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 …
