During vestibular function tests using the pendulum chair, electronystagmography has repeatedly shown that a tonic ocular deviation precedes the change in nystagmus. This tonic movement may be anticipated in respect to the change in the sinusoidal movement of the chair. Greiner, Conraux, Collard and more recently J.B. Causse, have proposed a hypothesis based on the own periodicity of the vestibular system. J. Max explained this phenomenon in terms of a difference in phase with the electronic system. Our investigation suggests another explanation of this phenomenon. Each half-period consists of a acceleration phase and a decelaration phase. Thus within half-period alone there are two successive forms of nystagmus induced. The succession of half-periods gives the usual systagmus response. We consider that the tonic response of the eyes is not an anticipated one in respect to the change in sinusoidal movement of the chair, but rather a delayed one in respect to the reversal in the direction of acceleration.
在使用摆椅进行前庭功能测试期间，眼震电图反复显示，在眼球震颤变化之前存在一种紧张性眼偏斜。就椅子的正弦运动变化而言，这种紧张性运动是可以预期的。格雷纳、孔罗、科拉尔以及最近的J.B. 科斯提出了一种基于前庭系统自身周期性的假说。J. 马克斯从与电子系统的相位差异方面解释了这一现象。我们的研究提出了对这一现象的另一种解释。每个半周期由一个加速阶段和一个减速阶段组成。因此，仅在半周期内就会诱发两种连续形式的眼球震颤。半周期的连续出现产生了通常的眼球震颤反应。我们认为，眼睛的紧张性反应并非相对于椅子正弦运动变化的预期反应，而是相对于加速度方向反转的延迟反应。
