Abstract
The relationship between eye position and body sway was examined. Using goggles equipped with prism lenses of 30 degrees, these goggles produced eye deviation of 17 degrees. Body sway was measured while the subject stood with feet together. The deviation of body sway was expessed as the difference of the center of body sway between the values with and without goggles. During upward gaze, the center of body sway deviated forwards. During rightward gaze the center of body sway deviated leftwards, and during leftward gaze, the center of body sway deviated rightwards. No characteristic pattern was observed during downward gaze. These relationship of eye position to body sway were in accordance with the pattern of tonic neck reflex.
