The frequency spectrum of the center of gravity in normal 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 three 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.
使用平台应变仪系统和数字计算机记录正常受试者站立时重心的频谱。频谱模式的个体差异导致分为三种类型。计算了每种类型在1Hz以下范围内的平均划分频率，在该范围内，睁眼和闭眼时的值之间的主要变化表现为频率偏移。
