The purpose of this study is to determine the normal range of stabilometry in children and the characteristics of upright standing posture. A group of 111 healthy children aged 4 to 15 years were tested. Each child was instructed to stand with feet close together at the center of a stabilometer with the eyes open and closed for 60 seconds, respectively. The sway of the center of gravity was sampled at 50 msec intervals by an analog-digital converter and stored in a microcomputer. From the stored data, the length of the sway, maximum diameter of forward-backward and right-left sways, area and center of the sway, probability density distribution of amplitude, velocity of sway and power spectrum were calculated with a specially designed program. 1. The length, maximum diameter, area, standard deviation of the probability density distribution of amplitude, and the velocity of the sway decreased with age. 2. The differences in the mean values of these measurements with the eyes open and with the eyes closed were large in children aged 4 to 8 years. 3. The center of sway was located further behind the center of the soles in children than in adults, and it moved forward with age. 4. The normal ranges of each parameter of stabilometry were described for each age-group.
