中文摘要
目的： 在健康成人中，使用气导500 Hz短纯音刺激，比较三种电极配置——眶下（标准）、颏部和腹-腱——用于眼部前庭诱发肌源性电位（oVEMP）。
方法： 在50名年龄22-55岁的健康志愿者（100耳）中进行了一项观察性横断面研究。所有志愿者均使用三种随机顺序的电极配置记录oVEMP。分析N1和P1潜伏期、峰间振幅和不对称比。
结果： 与眶下和颏部配置相比，腹-腱配置与更短的N1和P1潜伏期相关（p < 0.05），未观察到峰间振幅或不对称比的显著差异。未发现耳侧或性别差异，但注意到年龄与波间振幅之间存在显著负相关。
结论： 虽然腹-腱配置表现出更短的N1和P1潜伏期，但所有三种配置提供了可比的振幅和不对称比值。这些发现表明，电极配置的选择可能优先考虑患者舒适度、检查者经验和解剖特征。
英文摘要
OBJECTIVE: To compare three electrode montages - infraorbital (standard), chin and belly-tendon - for ocular Vestibular Evoked Myogenic Potential (oVEMP), using air-conducted 500 Hz tone burst stimulation in health adults.
METHODS: An observational cross-sectional study was conducted in 50 healthy volunteers (100 ears) aged 22‒55. oVEMP was recorded using three randomized electrode montages in all volunteers. N1 and P1 latencies, peak-to-peak amplitudes and asymmetry ratios were analyzed.
RESULTS: Belly-tendon montage was associated with shorter N1 and P1 latencies compared to both infraorbital and chin montages (p < 0.05) and no significant differences in peak-to-peak amplitudes or asymmetry ratios were observed. No ear side or sex differences were found, while a significant negative correlation between age and interamplitude was noted.
CONCLUSIONS: While the belly-tendon montage demonstrated shorter N1 and P1 latencies, all three configurations provided comparable amplitude and asymmetry ratio values. These finds suggest that electrode montage choice may prioritize patient comfort, examiner experience and anatomical characteristics.
