Abstract

Background: Motion sensitivity, or motion sickness, is common in modern vehicular and visually stimulating environments. Several studies have shown a relationship between motion sensitivity and decreased postural stability. We aimed to evaluate the effects of head motion (horizontal and vertical) on postural stability in healthy adults with and without chronic motion sensitivity (CMS).

Methods: Sixty healthy adult men and women (age, 20-40 years) with CMS (CMS group, n = 30) and without CMS (non-CMS group, n = 30) participated in the study. Postural stability was assessed during three conditions (static, horizontal head motion, and vertical head motion) using computerized dynamic posturography. Group and condition-related differences in equilibrium scores were evaluated.

Results: There was no significant group x condition interaction (F2,114 = 0.9, partial ƞ2 = 0.04, p = 0.35). However, significant condition-related differences in equilibrium scores were observed (F2,114 = 26.4, partial ƞ2 = 0.31, p < 0.001). Equilibrium scores were significantly worse in the horizontal and vertical head motion conditions compared to those in the static condition (p < 0.001), but were comparable in vertical and horizontal head motion conditions (p = 0.27).

Conclusions: Postural stability was lower in the horizontal and vertical conditions compared to the static condition. However, horizontal and vertical head motions had comparable effects on postural stability in both CMS and non-CMS groups, contrary to our expectations.

头部运动对慢性运动敏感的健康青年体位稳定性的影响。
背景:运动敏感或晕动病在现代车辆和视觉刺激环境中很常见。几项研究表明,运动敏感性和姿势稳定性下降之间存在关系。我们的目的是评估头部运动(水平和垂直)对有和没有慢性运动敏感(CMS)的健康成年人姿势稳定性的影响。方法:60名患有CMS (CMS组,n = 30)和未患有CMS(非CMS组,n = 30)的健康成年男女(年龄20 ~ 40岁)参与研究。在三种情况下(静态、水平头部运动和垂直头部运动),使用计算机动态姿势术评估姿势稳定性。评估各组和条件相关的平衡得分差异。结果:x组无显著相互作用(f2114 = 0.9,偏ƞ2 = 0.04, p = 0.35)。然而,在平衡得分上观察到显著的条件相关差异(f2114 = 26.4,偏ƞ2 = 0.31, p p p = 0.27)。结论:与静态状态相比,水平和垂直状态下的姿势稳定性较低。然而,水平和垂直头部运动对CMS组和非CMS组的姿势稳定性有相当的影响,与我们的预期相反。
