Background: Gait imbalance and oscillopsia are frequent complaints of bilateral vestibular loss (BLV). Video-head-impulse testing (vHIT) of all six semicircular canals (SCCs) has demonstrated varying involvement of the different canals. Sparing of anterior-canal function has been linked to aminoglycoside-related vestibulopathy and Menière’s disease. We hypothesized that utricular and saccular i...

We investigated how vestibulo-spinal reflexes (VSRs) and vestibulo-ocular reflexes (VORs) measured through vestibular evoked myogenic potentials (VEMPs) and video head impulse test (vHIT) outcomes, respectively, are modulated during standing under conditions of increased postural threat. Twenty-five healthy young adults stood quietly at low (0.8 m from the ground) and high (3.2 m) surface heigh...

OBJECTIVE To propose an etiology for a syndrome of bilateral vestibular hypofunction and sound and/or pressure-evoked eye movements with normal hearing thresholds. DESIGN Retrospective case series. SETTING Tertiary care referral center. PATIENTS Four patients with bilateral vestibular hypofunction, sound and/or pressure-evoked nystagmus and normal hearing thresholds were identified over a...

The vestibular system responds to head acceleration by producing compensatory reflexes in the eyes and postural muscles. In this study, we investigated the effect of brief interaural acceleration on the vestibular evoked myogenic potential (VEMP) in 10 normal subjects and 10 patients with bilateral (bVL) or unilateral vestibular loss (uVL). The stimuli were delivered with a handheld minishaker ...

diabetes mellitus type ι is a metabolic disorder that affects multiple systems including the inner ear. patients with diabetes mellitus commonly complain about dizziness, floating sensation, tinnitus and sweating. the aim of this study was to compare vestibular evoked myogenic potentials (vemps) between diabetic patients with or without neuropathy. subjects included 14 patients with diabetes me...

UNLABELLED The most important for the diagnosis of vestibular schwannoma is MRI technic, which allows assessing its size and shape. The gold diagnostic standard includes also PTA, SD and ABR, nystagmography with calorics and VEMP. Nystagmography with calorics reflects the status of superior vestibular nerve. The sensitivity of calorics amounts to 61-87%. VEMPs reflect the status of interior ves...

OBJECTIVES/HYPOTHESIS To evaluate vestibular function in patients with the mitochondrial A3243G mutation. STUDY DESIGN Data from patients with the A3243G mutation attending an academic tertiary referral center were prospectively recorded. METHODS The clinical histories of 13 unrelated patients with the mitochondrial A3243G mutation (six mitochondrial encephalomyopathy, lactic acidosis, and ...

A number of electrophysiological tests have been proposed for the initial diagnostic assessment or for the follow-up phase of patients affected by Ménière disease. The most common are: (i) vestibular evoked myogenic potentials (VEMPs); (ii) electrocochleography (ECochG); and (iii) otoacoustic emissions (OAEs). This paper presents the latest clinical developments with these 3 testing modalities....

BACKGROUND It is well-known that ocular vestibular evoked myogenic potentials (oVEMPs) predominantly reflect utricular function whilst cervical vestibular evoked myogenic potentials (cVEMPs) reflect saccular function. To date, there are no published reports on the systemic evaluation of utricular and saccular function in benign paroxysmal positional vertigo (BPPV), nor are there any reports on ...
