前庭诱发肌源电位（VEMP）是通过声音或振动激活前庭受体而诱发的一种短潜伏期电位。它是由调节的肌电信号产生的，或来自胸锁乳突肌的颈VEMP (cemp)，或来自下斜肌的眼VEMP （oVEMP）。这些反射似乎源于耳石器官，因此补充了现有的主要基于耳道功能的前庭评估方法。本文综述了cemp和oVEMP在评估和诊断外周和中枢前庭疾病中的基础、方法和当前应用。
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 cervicalVEMP (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.
