Abstract

In order to make clear the effect of aging on postural controlling ability in standing, we developed an evaluation system using a force plate and CRT monitor. In the present experiment, 14 young male (age 21∼24), 7 middle-aged male (age 30∼36), 5 middle-aged male (age 40∼45), 16 elderly male (age 59∼70), 17 elderly female (age 57∼70) subjects participated. The subject stood on the force plate in front of CRT monitor, and controlled center of gravity following a target dot which traveled on the CRT monitor. Both the postural sway of the subject and the target dot were displayed simultaneously. The length of postural sway and time course were respectively recorded during the experiment. The current results indicated that 1) the postural controlling ability decreased by aging, 2) all of the subjects showed higher postural controlling ability in forward than in backward, 3) the postural controlling ability in horizontal was the lowest in the elderly subjects, 4) the postural controlling area decreased by aging.
