電腦化旋轉前庭功能檢查之臨床經驗
Computerized Rotational Vestibular Test in Clinical Practice
摘要
背景：前庭功能試驗中，電腦化旋轉前庭檢查為一定量性之分析，經由準確之生理性刺激，同時引發丙水平半規管作用，藉前庭眼反射來評估前庭功能異常與否。臨床上較常使用之電腦化旋轉椅檢查，最主要以正弦諧波式加速試驗(sinusoidal harmonic acceleration test,SHAT) 及速度階段式試驗(velocity step test)為主。 方法：本部經過1年的臨床應用，除收集40名正常人接受電腦化旋轉前庭檢查外，並對不同臨床診斷之病患實施檢查以研究追蹤。 結果：由於各驗室不同之軟、硬體設備，所分析之數捙嚴所差異，本實驗室之標準正常數值範圍，與先前文獻報告相近，本研究在正常人正弦諧波式加速試驗檢查中增益值(gain)之變異性係數約為36%，並舉6例臨床病例進一步說明其臨床用途。 結論：電腦化旋轉前庭功能檢查已成為前庭功能查中之重要項目，本文建立本實驗室之標準正常值範圍，以作為檢查結果判讀與分析之重要參考依據。(中耳醫誌 1997;32:430-436)

Background: Among the quantitative vestibular testing, the computerized rotational vestibular test is widely used due to theprecise and physiological stimulus to evaluate the vestibule-ocular reflex function of the horizontal semicircular canals. It includes two major components: sinusoidal harmonic acceleration test (SHAT) and velocity step telst. Methods: this analysis includes 40 normal adults and six patients with the diagnosis of various vestibular discorders at the Tri-Service General Hospital during the past one year. Results: The normative data established in our study are similar to other reports in the literature. The coefficient of gain of SHAT is 36% in our study. Conclusions: By our clinical practice experience, many problems were found during the establishment of normative data and the examinations of the patients.
