Study Notes
- Vestibular Evoked Myogenic Potentials (VEMP) are electromyographic responses generated by vestibular labyrinth stimulation through sound, vibration or electrical stimuli.
- VEMP is a clinical test for otolith organs and related reflex pathways.
- Otolith organs in humans are called utricle and saccule.
- There are two types of VEMP tests: cVEMP and oVEMP.
- cVEMP records the otolith-ocular reflex through the sternocleidomastoid muscle while oVEMP records it through the inferior oblique muscle.
- cVEMP provides information about saccular function while oVEMP provides information about utricular function.
- VEMP waves are biphasic (positive-negative) waves.
- cVEMP is a mid-latency potential evaluating the vestibulo-collic reflex while oVEMP is an early-latency potential evaluating the utriculo-ocular reflex.
- The vestibulo-collic reflex pathway involves receptors (macula and saccule), afferent pathways, central connections, efferent pathways, XI cranial nerve motor nucleus, and affected muscles.
- The utriculo-ocular reflex pathway involves receptors (macula and utricle), afferent pathways, central connections, efferent pathways, III cranial nerve motor nucleus, and inferior oblique muscle.
