To investigate visual influence on aging in postural control, contact pressure distribution were analyzed by both photoelastic method in 38 subjects aged from 19 to 78 and gravity-movement drawer device in 80 subjects aged from 2 to 69. When their eyes were closed, the position of the center of contact pressure (CCP) between feet and floor was shifted significantly backwards in aged people in 70', whereas it shifted forwards in those below 60'. Body sway velocity became stable at 10', however it became unstable over 70'. These results suggest that central postural control matures at 10', and became unstable over 70'. Elderly people need more visual information to stabilize their posture as compared to young people so that sufficient light at night can help elderly people to prevent fall at home.
