A sharp distinction should be made between symptoms of motion-sickness per se and phenomena inferred from the symptomatology, which include rates of acquisition and decay of adaptation effects. Foreknowledge of these "derived phenomena" are valuable if it can be shown that they hold true for virtually any motion environment. Recently, we have developed a sudden-stop vestibulovisual interaction test for measuring susceptibility to motion sickness (1). The test procedure involves four successive assessments that provide not only an index of susceptibility to motion sickness but also the rates of acquisition and decay of adaptation effects. The 14 subjects participating in this test had previously served as subjects in parabolic flight experiments and seven of them had also taken part in the assessment of antimotion-sickness remedies in a slow rotation room. The present report examines whether their rates of acquisition and decay of adaptation to stressful motion represent consistent general features of their responses across motion environments. From these comparisons, it appears that an individual's rates of acquiring and losing adaptation are quite consistent in very different situations. The pattern of results also suggests modifications of the sudden-stop vestibulovisual test that should increase its effectiveness as a motion-sickness screening procedure, both for orbital flight and for terrestrial conditions.
晕动病本身的症状与从症状学推断出的现象之间应明确区分,这些现象包括适应效应的获得率和衰退率。如果能够证明这些“衍生现象”在几乎任何运动环境中都成立,那么对它们的预先了解是很有价值的。最近,我们开发了一种突然停止的前庭视觉相互作用测试来测量晕动病易感性(1)。测试程序包括四个连续的评估,这些评估不仅提供晕动病易感性指标,还提供适应效应的获得率和衰退率。参与该测试的14名受试者之前曾作为抛物线飞行实验的受试者,其中7人还参与了在慢速旋转室中对抗晕动病药物的评估。本报告研究了他们对压力运动的适应获得率和衰退率是否代表了他们在不同运动环境中反应的一致普遍特征。从这些比较中可以看出,个体在非常不同的情况下适应的获得率和丧失率相当一致。结果模式还表明,对突然停止的前庭视觉测试进行修改,应该会提高其作为晕动病筛查程序的有效性,无论是在轨道飞行还是地面条件下。
