OBJECTIVE To investigate saccular function using vestibular evoked myogenic potentials in children with congenital or early acquired sensorineural hearing loss. DESIGN Retrospective cohort study. SETTING Pediatric tertiary referral center. PATIENTS Twenty-three children with bilateral sensorineural hearing loss (severe to profound in 22 cases, moderate in 1 case) underwent evaluation of s...

OBJECTIVES The aim of this study was to evaluate latencies and corrected p13-n23 cervical vestibular evoked myogenic potentials (cVEMP) and n10-p13 ocular vestibular evoked myogenic potentials (oVEMP) amplitudes in patients with relapsing remitting multiple sclerosis (MS). METHODS This was a prospective, case-control study. Thirty patients with MS and 15 healthy controls were included. Cervic...

BACKGROUND Multiple sclerosis (MS) is a chronic neurological disease that affects brain and spinal cord. The infratentorial region contains the cerebellum and brainstem. Vestibular evoked myogenic potentials (VEMPs) are short-latency myogenic responses. Cervical vestibular evoked myogenic potential (cVEMP) is a manifestation of vestibulocolic reflex and ocular vestibular evoked myogenic potenti...

Vestibular reflexes in humans can be assessed by means of acoustically evoked responses of myogenic origin. For the vestibular-collic pathway this is termed the vestibular evoked myogenic potential (or VEMP) and for the vestibular-ocular pathway the ocular VEMP (or OVEMP). Usually VEMPs require an averaging process to obtain a clear response against the background myogenic activity, but dependi...

This is a review of recently published papers showing that bone-conducted vibration of the head causes linear acceleration stimulation of both inner ears and this linear acceleration is an effective way of selectively activating otolithic afferent neurons. This simple stimulus is used in a new test to evaluate clinically the function of the otoliths of the human inner ear. Single neuron studies...
