Abstract

We have united an immersive virtual environment with support surface motion to record biomechanical and physiological responses to combined visual, vestibular, and proprioceptive inputs. We have examined age-related differences during peripheral visual field motion and with a focal image projected on to the moving virtual scene. Our data suggest that the postural response is modulated by all existing sensory signals in a non-additive fashion. An individual's perception of the sensory structure appears to be a significant component of the postural response in these protocols. We will discuss the implications of these results to clinical interventions for balance disorders.
