Previous investigations suggest strong similarities between aftereffects of an 1.5-hour 3 gx centrifuge run (Sickness Induced by Centrifugation; SIC) and the Space Adaptation Syndrome (SAS). Head movements proved to be especially nauseogenic in both cases. Until recently, during SIC experimentation, the performance of head movements was not adequately operationalized, which hampered a statistical evaluation. For this purpose, a test was designed by which head movements in four directions (left, right, up, and down) were provoked and registered, once before and once after a 1-h 3 g centrifuge run. Subjects had to execute these head movements in order to perform well on a psychomotor task. The results indicate that the test described is sensitive in discriminating between subjects who are seriously affected after a long duration centrifugation and those who are not. Because differences in performance were found only on those parts of the task in which head movements were involved, objective evidence is obtained in favour of a vestibular cause in the etiology of SIC.
先前的研究表明，1.5小时3G的离心机运行后效（离心诱导疾病；SIC）与太空适应综合征（SAS）之间有很强的相似性。在这两种情况下，头部运动都被证明特别容易引发恶心。直到最近，在SIC实验期间，头部运动的表现没有得到充分的操作化，这妨碍了统计评估。为此，设计了一项测试，通过该测试在1小时3G离心机运行之前和之后各激发并记录一次四个方向（左、右、上和下）的头部运动。受试者必须执行这些头部运动，以便在一项心理运动任务中表现良好。结果表明，所描述的测试在区分长时间离心后受到严重影响的受试者和未受影响的受试者方面很敏感。由于仅在涉及头部运动的任务部分发现了表现差异，因此获得了客观证据，支持SIC病因中的前庭原因。
