聽覺刺激對前庭眼反射增益的影響

// Auditory Stimuli Influence on Vestibulo-Ocular Reflex Gains

本研究探討聽覺刺激對前庭眼動反射（VOR）增益的影響｜40名成人接受靜音及不同強度聲音測試，結果顯示高強度音調脈衝與白噪音減少側及前半規管的VOR增益｜低強度聲音及後半規管則無顯著影響，顯示聽覺主要經由上前庭神經調節VOR，且這項方法有助臨床前庭功能評估。

// This study investigated how auditory stimuli affect the vestibulo-ocular reflex (VOR) gain using a video head impulse test with controlled sounds. Forty adults underwent tests in silence and with various sounds presented at two intensity levels, including their individualized vestibular evoked myogenic potential (VEMP) threshold. Results showed that high-intensity sounds, particularly tone bursts and white noise, reduced VOR gain in the lateral and anterior canals, while lower-level sounds had no effect and the posterior canal was unaffected. The findings suggest auditory input modulates VOR mainly via the superior vestibular nerve, and the auditory-vHIT method could aid clinical vestibular assessments.
