Peripheral vestibular disorder (PVD) is serious and common. Clinically, giving an accurate diagnosis of PVD can be challenging. Therefore, this study was conducted to enhance the accuracy in diagnosing PVD by investigating two new tests, i.e. VEMP and MVVSS to be compared with caloric test and Dix-Hallpike test (DHT). In this study, 40 normal participants and 65 PVD subjects participated. Sensitivity and specificity of each test was then determined using ROC method. Among VEMP parameters, N1 amplitude of 750 Hz stimulus produced the most ideal sensitivity and specificity. In fact, VEMP was...
