Background and Objectives (Cervical vestibular evoked myogenic potentials (cVEMP) test has been widely used to assess the function of the saccule and inferior vestibular nerve. Electrode location and stimulating sound are important factors which might affect the test results. Today those parameters are usually selected to maximize the waveform response. In this study, we tried to find the optimal condition to minimize the range of normal value of cVEMP. Subjects and Method Thirteen normal subjects (26 ears) were included. We placed electrodes at five different locations over the sternocleidomastoid muscle (SCM) and used four different stimulation sounds. Variances of parameters, including interpeak amplitude, interaural difference (IAD) and normal value were analyzed and compared. Results When using the classical condition (mid point of SCM and 500 Hz) without rectification, IAD ratio was 20.8±14.2% and the range of normal value was 39%. When we used 2000 Hz tone burst sound at the classical electrodes site, IAD ratio and normal value were minimized, resulting in 18.7±14.3% and 31% respectively. After the rectification, when using the classical condition, IAD ratio was 26.4±22.3% and the range of normal value was 49%. The minimum IAD ratio was measured as 17.4±13.7% when we used click sound at SCM at the level of mandibular angle. And the minimum normal value of 32% was measured when we used 1000 Hz tone burst sound at SCM at the level of mandibular angle. Conclusion Although the condition was not optimal for maximizing the interpeak amplitude, we could alternatively use the condition to minimize the normal value.
