Two techniques of frequency analysis were performed to find pathognomonic characteristics of body sway in patients with equilibrium disorders or ataxia.A stabilometer using the straingauge technique was used to obtain, from a subject standing normally on the platform, a continuous record of the movement in the horizontal plane. The data was at the same time supplied to a data recorder, which separately stored the data of lateral and antero-posterior movements on the tape. The recorded data on the tape was fed into a digital computer for the spectral analysis and the calculation of averaged divisional frequencies.Careful investigation proved that the peak frequencies and the calculated averaged divisional frequencies are reliable indicators of frequency characteristics of the body sway, suggesting the possibility of their clinical application.
