Although there is general agreement that a high degree of variability exists between subjects in their autonomic nervous system responses to motion sickness stimulation, very little evidence exists that examines the reproducibility of autonomic responses within subjects during motion sickness stimulation. Our objectives were to examine the reliability of autonomic responses and symptom levels across five testing occasions using the (1) final minute of testing, (2) change in autonomic response and the change in symptom level, and (3) strength of the relationship between the change in symptom level and the change in autonomic responses across the entire motion sickness test. The results indicate that, based on the final minute of testing, the autonomic responses of heart rate, blood volume pulse, and respiration rate are moderately stable across multiple tests. Changes in heart rate, blood volume pulse, respiration rate, and symptoms throughout the test duration are less stable across the tests. Finally, autonomic responses and symptom levels are significantly related across the entire motion sickness test.
尽管人们普遍认为，在自主神经系统对晕动病刺激的反应方面，个体之间存在高度变异性，但几乎没有证据检验晕动病刺激期间个体自主反应的可重复性。我们的目标是使用以下方法，在五个测试时段检验自主反应和症状水平的可靠性：(1) 测试的最后一分钟；(2) 自主反应的变化和症状水平的变化；(3) 在整个晕动病测试中，症状水平变化与自主反应变化之间的关系强度。结果表明，基于测试的最后一分钟，心率、血容量脉搏和呼吸频率的自主反应在多次测试中具有中等稳定性。在整个测试过程中，心率、血容量脉搏、呼吸频率和症状的变化在各次测试中稳定性较差。最后，在整个晕动病测试中，自主反应和症状水平显著相关。
