前庭装置是静动分析器,半规管壶腹嵴感受器感受角加速度作用所致的平衡变化,囊斑则感受重力变化和直线加速度作用。前庭功能临床检查最常用者为用定量旋转刺激外半规管,以了解其兴奋性阈值。有三种阈值指标,即:①运动感知阈(TMS):刚有主观运动感时的最小角速度值;②反向转动幻觉阈(TCI):
Vestibular device is a static and dynamic analyzer, semi-regulatory ampulla crest feel the angular acceleration caused by changes in equilibrium, the cyst is to feel the changes in gravity and linear acceleration. The most common clinical test for vestibular function is the use of quantitative rotation of the outer semicircular canal to understand its excitability threshold. There are three threshold indicators, namely: ① motion perception threshold (TMS): the moment of subjective sense of motion when the minimum angular velocity; ② reverse illusion threshold (TCI):
