Abstract
The stabilometric velocity vector has been evaluated qualitatively by sway pattern and/or partially quantitatively by Romberg's coefficient. We examined distributions of the statistical parameters of stabilometric velocity vectors in 89 normal subjects. Each subject had 36 vectors measured with the stabilometer, into which were divided by 10 degrees from 0° to 360°. From these 36 data, we calculated, for each subject, the parameters: coefficient of variation (C. V.), skewness and kurtosis. The skewness was subject to normal distribution. The C. V. and the kurtosis were log-normal distribution. These parameters can quantitatively represent the comprehensive characteristics of the velocity vector.
