Abstract

The purpose of the present study was to investigate the influences of three visual conditions on postural control among young and older adults and between males and females. The visual conditions were: eyes closed; eyes open with constant visual fixation; and eyes open with random visual fixation. Older adults demonstrated a significantly greater magnitude of lateral sway than younger adults, substantiating an age-related deterioration in postural control. Also, normalized data supported an age-related difference. Males demonstrated significantly greater lateral sway than females. This difference was not noted when lateral sway was normalized to support base width. No statistically significant gender-related differences were noted for antero-posterior sway. The visual contribution to postural control was the same for younger and older adults and for males and females. Constant visual fixation was the condition which provided the most stabilization for all groups. All groups demonstrated a destabilizing effect in the lateral plane of sway for random visual fixation and for eyes closed. (Abstract shortened by UMI.)Dept. of Kinesiology.
