The vestibular-evoked myogenic potential (VEMP) is a short-latency potential evoked through activation of vestibular receptors using sound or vibration. It is generated by modulated electromyographic signals either from the sternocleidomastoid muscle for the cervical VEMP (cVEMP) or the inferior oblique muscle for the ocular VEMP (oVEMP). These reflexes appear to originate from the otolith organs and thus complement existing methods of vestibular assessment, which are mainly based upon canal function. This review considers the basis, methodology, and current applications of the cVEMP and oVEMP in the assessment and diagnosis of vestibular disorders, both peripheral and central.
前庭诱发肌源性电位（VEMP）是一种通过声音或振动激活前庭感受器而诱发的短潜伏期电位。它由调制的肌电信号产生，对于颈前庭诱发肌源性电位（cVEMP）来说，信号来自胸锁乳突肌；对于眼前庭诱发肌源性电位（oVEMP）来说，信号来自下斜肌。这些反射似乎起源于耳石器官，因此补充了现有的前庭评估方法，现有方法主要基于半规管功能。本文综述了cVEMP和oVEMP在评估和诊断外周及中枢前庭疾病方面的基础、方法和当前应用。
