Spectral analysis of body sway

, : Spectral analysis of body sway. Orl; Journal for Oto-Rhino-Laryngology and Its Related Specialties 39(6): 330-337

The frequency spectrum of the center of gravity in normal [human] subjects while standing was recorded by using a platform-strain gauge system and a digital computer. Individual differences of the spectral patterns resulted in the classification of 3 types. Averaged divisional frequency of each type was calculated in the range below 1 Hz in which the main change between the values with eyes open and those with eyes closed appeared as the frequency shift.
