Vestibular evoked myogenic potentials. The testing of Vestibular Evoked Myogenic Potentials has become a well-established approach for the exploration of sacculocollic pathways. Two types of tests have been described: VEMP induced by high intensity sound (click or tone burst) and VEMP induced by galvanic stimulation. We describe a method for recording the VEMP using both types of stimulation, and how to interpret them, and we report several clinical applications. Each of these techniques activates the vestibular afferents in different ways, and is a complementary tool for testing vestibular function at the level of the saccule or the inferior vestibular nerve.
