Objectives We retrospectively evaluated a chart review of 3,525 patients for any acute disturbance. A total 1,504 with vestibular syndrome (AVS) received an instrumental assessment within 72 h from the onset symptoms using simultaneously combination ocular vestibular-evoked myogenic potential (oVEMPs), cervical (cVEMPs), video head-impulse test (vHIT), and subjective visual vertical (SVV) were ...

Aim:To evaluate vestibular evoked myogenic potentials in patients with multiple sclerosis as method of diagnostic support. Study design: Case-control. Material and Method: We studied a group of normal individuals (n=15) and a Studied group (n=15) that comprised patients with diagnosis of multiple sclerosis. Both groups were submitted to vestibular evoked myogenic potential exam. In each ear it ...

OBJECTIVE Galvanic vestibular stimulation (GVS) delivered as zero-mean current noise (noisy GVS) has been shown to improve static and dynamic postural stability probably by enhancing vestibular information. The purpose of this study was to examine the effect of an imperceptible level noisy GVS on ocular vestibular-evoked myogenic potentials (oVEMPs) in response to bone-conducted vibration (BCV)...

Vestibular Evoked Myogenic Potentials (VEMPs) have recently become a popular component of the audiovestibular test battery of many neurology, otolaryngology, and audiology laboratories and clinics. Traditional VEMPs, resulting from the vestibulo-collic reflex, are evoked by intense acoustic stimuli presented via air or bone conduction and recorded from the activated ipsilateral neck musculature...

Extracellular single neuron recording and labelling studies of primary vestibular afferents in Scarpa's ganglion have shown that guinea-pig otolithic afferents with irregular resting discharge are preferentially activated by 500 Hz bone-conducted vibration (BCV) and many also by 500 Hz air-conducted sound (ACS) at low threshold and high sensitivity. Very few afferent neurons from any semicircul...

OBJECTIVE Electrical stimulation of the utricular and saccular portions of the vestibular nerve improves stability in patients suffering from vestibular dysfunction. The main objective of this study was to evaluate a new technique, vestibular response telemetry (VRT), for measuring the electrically evoked vestibular compound action potential (saccular and utricular) after stimulating the otolit...

  Background :Preterm birth is a significant global health problem with serious short- and long-term consequences. This study examined the long term effects of preterm birth on vestibular evoked myogenic potentials (VEMPs) among preschool-aged children.   Methods : Thirty-one children with preterm and 20 children with term birth histories aged 5.5 to 6.5 years were studied. Each child underwent...

OBJECTIVE To determine the amplitude changes of vestibular evoked myogenic potentials (VEMPs) recorded simultaneously from the neck (cVEMPs) and eyes (oVEMPs) in response to 500 Hz, 2 ms air-conducted sound pips over a 30 dB range. METHODS Fifteen healthy volunteers (mean age 29, range 18-57 years old) and one patient with unilateral superior canal dehiscence (SCD) were studied. The stimulus ...
