Astronauts, particularly in Skylab flights, experienced varying degrees of motion sickness lasting 3-5 d. One possible mechanism for this motion sickness adaptation is believed to be a reduction in otolith sensitivity with an attendant reduction in sensory conflict. In an attempt to determine if this hypothesis is valid, a ground-based pilot study was conducted on a vertical linear accelerator. The extent of habituation to accelerations which initially produced motion sickness was evaluated, along with the possible value of habituation training to minimize the space motion sickness problem. Results showed that habituation occurred for 6 of the 8 subjects tested. However, in tests designed to measure dynamic and static otolith function, no significant differences between pre- and post-habituation tests were observed. Cross habituation effects to a standard Coriolis acceleration test were not significant. It is unlikely that ground-based pre-habituation to linear accelerations of the type examined would alter susceptibility to space motion sickness.
宇航员，尤其是在天空实验室飞行任务中的宇航员，经历了持续3至5天不同程度的晕动病。这种晕动病适应的一种可能机制被认为是耳石敏感性降低以及随之而来的感觉冲突减少。为了确定这一假设是否成立，在一台垂直线性加速器上进行了一项地面飞行员研究。评估了对最初会引发晕动病的加速度的适应程度，以及适应训练对于将太空晕动病问题降至最低的可能价值。结果显示，在接受测试的8名受试者中，有6人出现了适应现象。然而，在旨在测量动态和静态耳石功能的测试中，未观察到适应前和适应后测试之间存在显著差异。对标准科里奥利加速度测试的交叉适应效应并不显著。对所研究类型的线性加速度进行地面预适应，不太可能改变对太空晕动病的易感性。
