Body sway responses evoked by a horizontal acceleration of a level and firm support surface are particular in that the vestibular information on body-space angle BS resembles the proprioceptive information on body-foot angle BF. We compared corresponding eyes-closed responses of vestibular-able (VA) and vestibular-loss (VL) subjects, postulating a close correspondence. In contradistinction to previous studies, we used an unpredictable (pseudorandom) stimulus and found that the eyes-closed and eyes-open responses of the VA closely resembled those of the VL subjects, as expected. We further conclude that the vestibular signals coding head linear translation in VA subjects has in this case too little functional relevance to cause a notable difference between the subject groups.

由水平和牢固支撑表面的水平加速度引起的摇摆响应特别之处在于，关于体空间角BS的前庭信息类似于关于体脚角BF的本体感受信息。我们比较了前庭能力（VA）和前庭损失（VL）受试者的相应闭眼反应，推测出密切的对应关系。与以前的研究相反，我们使用了不可预测的（伪随机）刺激，发现VA的闭眼和睁眼反应与预期的VL受试者非常相似。我们进一步得出结论，在这种情况下，VA受试者中编码前脑线性翻译的前庭信号的功能相关性太低，无法在受试者组之间产生显着差异。
