In order to develop a quantitative evaluation method for motion sickness, physiological signals were recorded during motion sickness. Thirteen normal subjects were provided with Coriolis cross-cupled rotation (sinusoidal vertical rotation during continuous horizontal rotation of the whole body) for up to 20 minutes. Electrodermogram (EDG) was recrded between the forehead (anode) and the ear lobe (cat6hode). Tidal air was continuously sampled, and respiratory periods and endotidal CO_2 concentrtion were measred. The severity of motion sickness was evauated by the subjects every minute by means of the sbsolute judgment method. EDG in the thermal sweating area (i .e. Forehead), which negatively polarized in the normal condition, depolarized during motion sickness. Respiratory period did not change in average, but ts variance enlarged. Endotidal CO_2 concetration remarkably diminished. The depolarization of EDG and the drop of endotidal CO_2 concentration were significantly correlated with the severity of motion sickness

为了建立一种定量评价晕动病的方法，对晕动病患者的生理信号进行了记录。13名正常受试者进行科里奥利交叉耦合旋转（全身连续水平旋转的同时进行正弦垂直旋转），时间长达20分钟。记录前额（阳极）和耳垂（阴极）之间的皮肤电图（EDG）。连续采样潮汐空气，测量呼吸周期和潮内CO_2浓度。采用绝对判断法对被试每分钟的晕动病严重程度进行评价。热汗区EDG(即：前额)，在正常情况下呈负极化，在晕动病期间去极化。呼吸期平均变化不大，但方差增大。潮内CO_2浓度显著降低。EDG去极化和潮内CO_2浓度下降与晕动病严重程度显著相关
