内容記述 | This study aimed to assess individual and gender differences in power spectra in the body sway time series and sway velocity time series during a static upright standing posture using 30 preschool children and their spectrum distribution characteristics. The center of pressure (COP) movement for 1 min was measured twice with a 1 min rest on an Anima stabilometer. The data sampling frequency was 20 Hz. A power spectrum was calculated by applying a fast Fourier transform to time series data of X (medial/lateral) and Y (anterior/posterior) directions. The coefficient of variation (CV) over 10.0 of power was large (from 0.06 to 1.4 Hz in both directions), and as the frequency increased, the CV decreased. There were significant gender differences in the low frequency bands (less than 2.0 Hz), and almost all power of body sway time series and velocity time series were found in the low frequency bands (A and B sections) of the international standard. Individual differences were also large. The distribution of power spectra of their time series was different in both directions. These results suggest that the evaluation section of the existing international standard cannot properly evaluate periodic characteristics of body sway time series and sway velocity time series of preschool children. © Springer-Verlag Italia 2008. | |||||
