Cervical vestibular-evoked myogenic potential (cVEMP) and ocular VEMP (oVEMP) stimuli can be used to measure otolith function using air (AC) and bone conducted (BC) stimuli. Cervical VEMPs reflect saccular function and can be recorded using air conduction (AC), whereas oVEMPs reflect probably predominantly utricular function. Air- and bone-conducted vibration can be used, because AC oVEMP methodology seems to be fast and simple in clinical practice to measure otolith function. In this study we discuss the advantages and problems of AC oVEMP stimulation. AC oVEMP can be easily and quickly obtained within a few seconds. N10 (first negative peak) and p15 (first positive peak) latencies may be used as parameters for clinical interpretation but amplitude fluctuations are relatively large. For daily clinical use of VEMP visualization in a normogram seems feasible. Especially the AC oVEMP methodology (100 dB nHL, tone burst 500 Hz) is fast and efficient in clinical practice to measure otolith function, predominantly utricular function.
颈前庭诱发肌源性电位（cVEMP）和眼前庭诱发肌源性电位（oVEMP）刺激可用于通过气导（AC）和骨导（BC）刺激来测量耳石功能。颈VEMP反映球囊功能，可通过气导记录，而oVEMP可能主要反映椭圆囊功能。气导和骨导振动均可使用，因为在临床实践中，AC oVEMP方法似乎快速且简单，可用于测量耳石功能。在本研究中，我们讨论了AC oVEMP刺激的优点和问题。AC oVEMP可在几秒钟内轻松快速获得。N10（第一个负峰）和p15（第一个正峰）潜伏期可用作临床解读的参数，但幅度波动相对较大。对于VEMP在常态图中的日常临床应用似乎是可行的。特别是AC oVEMP方法（100 dB nHL，500 Hz短纯音）在临床实践中快速且高效，可用于测量耳石功能，主要是椭圆囊功能。
