摘要

摘要目的研究年轻健康女性在月经周期不同阶段的前庭反射(VOR)增益功能和VOR增益不对称性。该研究还旨在描述在月经周期的不同阶段是否存在纠正性扫视。方法29名年轻健康女性参与研究。在月经周期的各个阶段分别在侧、左前、右后、右前、左后平面进行视频头脉冲测试(vHIT),观察VOR增益函数的变化和VOR增益不对称比的变化。结果经方差检验的重复测量分析,所有受试者在月经周期各阶段的VOR增益函数和VOR增益不对称比均未出现显著的主效应。结果表明,健康女性在月经周期内,其VOR增益函数和VOR不对称比无明显变化。此外,在月经周期的各个阶段,整个参与者组都没有出现扫视现象。结论由于年轻健康女性的VOR增益函数在月经周期的各个阶段没有变化,因此在vHIT测试中对女性参与者进行测试时无需考虑月经周期的各个阶段。

Effects of Menstrual Cycles on VOR Gain Functions
Abstract Purpose The aim of the present study was to assess the vestibuloocular reflex (VOR) gain function and VOR gain asymmetry during the various phases of the menstrual cycle in young healthy female participants. The study also aimed to characterize the presence or absence of corrective saccades during the various phases of the menstrual cycle. Method Twenty-nine young healthy females participated in the study. The video head impulse test (vHIT) was performed in lateral, left anterior right posterior, and right anterior left posterior plane during the various phases of the menstrual cycle to see the changes in VOR gain function and VOR gain asymmetry ratio changes. Results A repeated measure analysis of variance test did not show any significant main effect for the VOR gain function and VOR gain asymmetry ratio in various phases of the menstrual cycle in all the participants. The result suggested no changes in VOR gain function and VOR asymmetry ratio in healthy females during the menstrual cycle. Also, there was an absence of saccades in the entire participants group during the various phases of the menstrual cycle. Conclusions As the VOR gain function does not change during the various phases of the menstrual cycle in young healthy females, there is no need to consider the various phases of the menstrual cycle while testing any female participant during the vHIT test.
