Development of multisensory reweighting is impaired for quiet stance control in children with developmental coordination disorder (DCD).
<h4>Background</h4>Developmental Coordination Disorder (DCD) is a leading movement disorder in children that commonly involves poor postural control. Multisensory integration deficit, especially the inability to adaptively reweight to changing sensory conditions, has been proposed as a p...
