The qualitative and quantitative correspondence between the degree of motion discomfort and the skin potential reflex (SPR) was examined in four subjects. Head movement was provided three times during body rotation at three different angular velocities (Coriolis stimulus) to induce motion discomfort, and at rest as a control. SPRs were caused in the arousal sweat area by head movement. The wave form, latency, time-to-peak, and amplitude of SPR were analyzed. The amplitude of the depolarizing response (P response) of SPR increased proportionally to the angular velocity of body rotation and decreased in the course of repetitive Coriolis stimulation. It was revealed that the amplitude of P response of SPR in the arousal sweat area corresponds to the degree of transient motion discomfort.
在四名受试者中研究了运动不适程度与皮肤电位反射（SPR）之间的定性和定量对应关系。在身体以三种不同角速度旋转时（科里奥利刺激），头部运动进行三次以诱发运动不适，并在休息时作为对照。头部运动在觉醒出汗区域引发了SPR。分析了SPR的波形、潜伏期、峰值时间和幅度。SPR去极化反应（P反应）的幅度与身体旋转的角速度成比例增加，并在重复的科里奥利刺激过程中降低。结果表明，觉醒出汗区域SPR的P反应幅度与短暂运动不适程度相对应。
