OBJECTIVE
This study aimed to examine the individual differences and factors affecting balance and gait control during walking (i.e., dynamic equilibrium) in healthy young adults subjected to unilateral caloric vestibular stimulation (CVS).
METHODS
Sixty-six participants completed questionnaires related to motion sickness. All participants were subjected to the head-up tilt test (HUT), which assesses orthostatic dysregulation, followed by inner ear stimulation with cold water (20°C) for 60 s. Subsequently, all participants performed a 6 m walking test with their eyes open.
RESULTS
CVS resulted in horizontal nystagmus. The measured distance of sway from the centerline on the goal line ranged from 0 to 600 cm. Both motion sickness and orthostatic dysregulation (OD) were associated with the distance of sway from the centerline.
CONCLUSIONS
Autonomic dysfunction affects the dynamic equilibrium and might cause individual gait differences. Further study is warranted to quantify the autonomic function and clarify individual variations in dynamic equilibrium, after unilateral CVS.
目的
本研究旨在探讨单侧冷热水前庭刺激（CVS）对健康年轻成年人行走时平衡和步态控制（即动态平衡）的个体差异和影响因素。
方法
66 名参与者完成了与晕动病相关的问卷。所有参与者均接受了头高位倾斜试验（HUT），以评估直立调节障碍，随后用 20°C 的冷水对内耳进行 60 秒刺激。之后，所有参与者睁眼进行 6 米步行测试。
结果
CVS 导致水平性眼球震颤。目标线上从中心线的摆动距离范围为 0 至 600 厘米。晕动病和直立调节障碍（OD）均与中心线的摆动距离有关。
结论
自主神经功能障碍会影响动态平衡，并可能导致个体步态差异。需要进一步研究来量化单侧 CVS 后自主神经功能，并阐明动态平衡的个体差异。
