Variation between individuals in sensorimotor feedback control of standing balance

Abstract
This study details naturally occurring intersubject variation in healthy adults' balance control. Experimental surface tilts evoked postural sway and sensorimotor modeling defined feedback control parameters. We determined the relation between intersubject variation in feedback control (vestibular and proprioceptive reliance, neural time delay, sensory-to-motor scaling) and intersubject variation in postural sway between planes of motion and between stimulus amplitudes.
