The long-term goal is to increase the sensitivity and specificity of the oVEMP when...

Vestibular System in Migrainous Vertigo Patients

Do migrainous vertigo patients have more pathology in their vestibular system than migraine patients without vertigo? The aim of this study is to compare the vestibular system of migraine patients with and without vertigo in the symptom-free period by vestibular function tests, videonystagmography, vestibular evoked myogenic potentials, and subjective visual vertical.


Recently, new clinical testing of saccular and utricular function have been developed and validated, the so-called vestibular-evoked myogenic potentials - VEMP (Brantberg et al. 2009, Cornell et al. 2009, Curthoys 2010, Manzari et al. 2012). Among them, the cervical VEMP (cVEMP) are short-latency electromyographic (EMG) modulations of the contracted sternocleidomastoid muscles in responses to vibration applied on the forehead. The clinical literature suggests that cVEMP are alm...

After that they received placebo or caffeine capsule (3...

OVEMP in Myasthenia

Myasthenia gravis is an autoimmune disorder of neuromuscular transmission, characterized by fluctuating muscle weakness and fatigability. In isolated ocular myasthenia, when only the extraocular muscles are involved, most common ancillary tests, such as acetylcholine receptor autoantibodies and repetitive nerve stimulation, are often negative. A simple, quick and non-invasive test for ocular myasthenia based on ocular vestibular evoked myogenic potentials (oVEMP) was recently ...

Vestibular Evoked Myogenic Potentials in Benign Paroxysmal Positional Vertigo (VEMP in BPPV)

Benign Paroxysmal Positional Vertigo (BPPV) is the most frequent cause of vertigo of peripheral vestibular origin with life time incidence of 2.4%. BPPV is characterized by bouts of acute whirling vertigo lasting less than one minute provoked by changes in head position in relation to the gravitational vector. The vertigo is accompanied by typical rotational or horizontal nystagmus that is often demonstrated by the Dix-Hallpike maneuver and less frequently by testing for positi...

Effect of Changing Physiological Conditions on Myogenic Oscillations: Pilot Study

Does Vestibular Rehabilitation Significantly Improve the Level of Vestibular Function Following Vestibular Neuritis?

To investigate which treatment option (corticosteroid treatment alone or combined corticosteroid treatment and vestibular rehabilitation) is the most effective in patients diagnosed with vestibular neuritis.

Effects of a Vestibular Rehabilitation Maneuver

Rotational maneuver is a vestibular rehabilitation method, performed in a supervised manner. Using a rotating chair, subjects are rotated towards the opposite direction of dominant side in order to inhibit this side and simultaneously, stimulate the subordinate side. We propose that the rehabilitative effect is the result of a decrease in the vestibular imbalance, mainly due to a decrease in the response of the dominant vestibular side. Previously, we have shown the short-term ...
