Poster 145 Visuomotor Reaching Behavior to Virtual and Real Targets Depends on Postural Requirements in Healthy Elders

METHODS DISCUSSION Objective: There has been much enthusiasm for the use of virtual environments in rehabilitation settings1,2,3. However, little is known of how rehabilitative outcomes (motoric or cognitive) of virtual reality (VR) compare to those of traditional exercises1. We investigated behavioral and cognitive performance differences in adults as they performed goaldirected arm reaches under two exposure conditions using virtual and real targets, and under varied dynamic balance demands. To determine meaningful differences in performance between target exposures, we would need to hold reaching distances constant across the two exposures. Here, we validate our ability to control for reaching distance through analysis of participant performance across exposures.
