As part of a program to develop a treatment for motion sickness based on self-regulation of autonomic nervous system (ANS) activity, this study examined the stability of an individual's pattern of ANS responses to motion sickness stimulation on repeated occasions. Motion sickness symptoms were induced in 58 people during 2 rotating chair tests. Physiological responses measured were heart rate, finger pulse volume, respiration rate, and skin conductance. Using standard scores, we examined stability of responses of specific magnitudes across both tests. Correlational analyses, analysis of variance, and a components of variance analysis all revealed marked, but quite stable, individual differences in ANS responses to both mild and severe motion sickness. These findings confirm our prior observation that people are sufficiently unique in their ANS responses to motion sickness provocation to make it necessary to individually tailor self-regulation training. Further, these data support our contention that individual ANS patterns are sufficiently consistent from test to test so as to serve as an objective indicator of individual motion sickness malaise levels.
作为基于自主神经系统(ANS)活动自我调节开发晕动病治疗方法项目的一部分,本研究考察了个体对晕动病刺激的ANS反应模式在重复测试时的稳定性。在2次转椅测试中,对58人诱发了晕动病症状。测量的生理反应包括心率、手指脉搏容积、呼吸频率和皮肤电导率。使用标准分数,我们考察了两次测试中特定强度反应的稳定性。相关分析、方差分析和方差成分分析均显示,在对轻度和重度晕动病的ANS反应中存在显著但相当稳定的个体差异。这些发现证实了我们之前的观察结果,即人们对晕动病激发的ANS反应具有足够的独特性,因此有必要进行个性化的自我调节训练。此外,这些数据支持了我们的观点,即个体的ANS模式在不同测试之间具有足够的一致性,可作为个体晕动病不适程度的客观指标。
