Abstract

This study was designed to quantify postural sway in healthy elderly females during the Clinical Test for Sensory Interaction in Balance. Sixteen females who ranged in age from 65 to 83 participated. Each individual performed three trials of the test on the Balance Master{dollar}\sp\circler{dollar}, which recorded percent postural sway area. Sway values from the third trial were used in data analysis.; Using a repeated measures ANOVA (F(5,75) = 33.38, p {dollar}<{dollar}.01), statistical significance was found between conditions. The post hoc Tukey's determined increased postural sway in conditions 5 and 6 (M = 1.8175 and 1.7425 respectively, p {dollar}<{dollar}.05). Results indicated postural sway increased with intersensory conflict (altered somatosensation and altered or eliminated vision) leading to the conclusion that healthy elderly females relied heavily on somatosensory and visual input for maintenance of standing balance.
