Ocular vestibular evoked myogenic potentials in superior canal dehiscence [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 2008
Patients with superior canal dehiscence (SCD) have large sound-evoked vestibular reflexes with pathologically low threshold. We wished to determine whether a recently discovered measure of the vestibulo-ocular reflex-the ocular vestibular evoked myogenic potential (OVEMP)-produced similar high-amplitude, low-threshold responses in SCD, and could ...

Ocular and cervical vestibular evoked myogenic potentials in multiple sclerosis patients

Clinical Neurophysiology, 2012
Vestibular evoked myogenic potentials (VEMPs) are thought to provide useful information about brainstem functions, as the neural pathways of both ocular and cervical VEMPs pass through the brainstem. The aim of this study was to investigate the clinical value of ocular and cervical VEMP tests in the evaluation of brainstem involvement in multiple ...

Asymmetric Ocular Vestibular Evoked Myogenic Potentials in Pediatric Vestibular Migraine

Otology & Neurotology, 2023
Objective Although ocular vestibular evoked myogenic potentials (oVEMP) abnormalities have been associated with vestibular migraine (VM) in adults, no studies have evaluated this in pediatric patients with VM. oVEMP asymmetry with normal cervical VEMP (cVEMP) findings may be a reliable VM biomarker in adults.

Normal Characteristics of the Ocular Vestibular Evoked Myogenic Potential

Journal of the American Academy of Audiology, 2011
Background:Stimulus-evoked electromyographic changes can be recorded from the extraocular muscles. These short-latency negative-polarity evoked myogenic potentials are called ocular vestibular evoked myogenic potentials (oVEMPs). To date there has not yet been a large-scale study examining the effects of age on the amplitude, latency, threshold, and ...

Aging Effect on the Ocular Vestibular-Evoked Myogenic Potentials

Otology & Neurotology, 2010
This study applied ocular vestibular-evoked myogenic potential (oVEMP) tests in healthy subjects of various ages to measure the effect of aging on oVEMPs quantitatively.Prospective study.University hospital.Seventy healthy subjects with the ages ranging from 24 to 76 years were divided into 6 groups by decade.

Ocular and Cervical Vestibular Evoked Myogenic Potentials in Patients With Vestibular Migraine

Otology & Neurotology, 2018
Objective:To evaluate the relationship between normal and abnormal ocular vestibular evoked myogenic potentials (oVEMP) and cervical vestibular evoked myogenic potentials (cVEMP) in patients with and without vestibular migraine (VM).Study Design:Retrospective review of oVEMP and cVEMP results in patients with vestibular disorders who were assessed ...

Ocular vestibular evoked myogenic potentials are abnormal in internuclear ophthalmoplegia

Clinical Neurophysiology, 2011
The cervical vestibular evoked myogenic potential (cVEMP) is sensitive to lower brainstem lesions affecting the vestibulo-collic pathway. We wished to determine whether the ocular VEMP (oVEMP), a recently-described otolith-ocular reflex, is also abnormal in patients with brainstem lesions.

Frequency tuning properties of ocular vestibular evoked myogenic potentials

NeuroReport, 2009
Loud air-conducted sound or bone-conducted vibration produces vestibular-dependent electromyographic responses both in the cervical muscles (cervical vestibular evoked myogenic potentials) and in the extraocular muscles (ocular vestibular evoked myogenic potentials; oVEMPs).
