Health examination using stabilometry was studied to check the health condition from the standpoint of body equilibrium.Using a stabilometer, sway of the center of gravity in upright standing was recorded with eyes open and closed for 60 seconds. The parameters measured were the area, locus length, right-left and forward-backward deviation of the center of sway, power spectrum, position and velocity vectors and standard deviation, skewness and kurtosis of amplitude histogram. Each measurement value was compared with standard values in healthy subjects and evaluated as stable (normal) or unstable (abnormal). The stabilometry was carried out in 1179 subjects of the ages 19-87.1. The relationship of the parameters measured to the detection rate of the abnormal indicated that stabilometry evaluating area and right-left deviation was suitable for health checkup.2. The number of subjects evaluated as abnormal in the stabilometry among care staff was significantly more than that among office staff.3. The number of subjects with hypertension, high arteriosclerosis index and low glucose tolerance in the abnormal group in the stabilometry was significantly more than that in the normal group.Stabilometry evaluating area and right-left deviation was useful for checking on health condition and detecting dangerous factors of cerebral vascular disorders.
