migraine is a neurologic disease, which often is associated with a unilateral headache. vestibular abnormalities are common in migraine. vestibular evoked myogenic potentials (vemps) assess otolith function in particular functional integrity of the saccule and the inferior vestibular nerve. we used vemp to evaluate if the migraine headache can affect vemp asymmetry parameters. a total of 25 pat...

OBJECTIVE To assess vestibular function in a large group of vestibular schwannoma patients so that we could determine whether simple vestibular exercises speed vestibular dysfunction recovery after tumor removal surgery. STUDY DESIGN A prospective investigation of the vestibular dysfunction experienced by patients in the first 12 weeks after surgery. SETTING Vestibular investigation unit at...

background and aim: motion sickness (ms) is usually generated when there is a mismatch between the senses which serve balance. one of these senses is related to vestibular system, so it is highly possible that ms reflects in vestibular test results. but there are some conflicts in correlation between vestibular findings and ms. thus, the objective of this study was to provide an overview of ves...

OBJECTIVE: 1) To correlate caloric results with sinusoidal and step-velocity rotary chair gain, phase, asymmetry and time constant values in all patients; 2) To evaluate sensitivity, specificity, positive predictive value and negative predictive value of both tests in patients with vestibular dizziness. STUDY DESIGN: Retrospective case review. SETTING: Academic tertiary care vestibular function...

OBJECTIVE We investigated the potential of galvanic vestibular stimulation (GVS) to quantify lateralised asymmetry of the vestibulospinal pathways by measuring balance responses to monaural GVS in 10 subjects with vestibular schwannoma and 22 healthy control subjects. METHODS Subjects standing without vision were stimulated with 3 s, 1 mA direct current stimuli delivered monaurally. The mean ...

Introduction: The majority of the daily life activities involve the concurrent performance of simultaneously challenging motor and cognitive activities, such as talking while walking, which requires the vestibular system for balance. Functional balance allows the brain to interpret and integrate the sensory information from our physical and social environment. This study aimed to investig...

BACKGROUND Dizziness is the most common symptom in elderly patients and has been identified as a risk factor for falls. While BPPV is the most common cause of dizziness among elderly, multisensory deficits is the second, with visual, vestibular and proprioceptive reduced function. Asymmetric vestibular function is overrepresented in elderly persons with hip fractures and wrist fractures and can...

The symmetry of primary and secondary optokinetic afternystagmus (OKAN I and OKAN II, respectively) was studied in 14 patients with vestibular neuritis, as well as in 50 normals. The patients were examined at onset of symptoms and at follow-up 3 and 12 months later. At onset, OKAN was found mainly to reflect the spontaneous nystagmus. Although the spontaneous nystagmus disappeared in all patien...

The human vestibular system comprises five motion detectors, being the three semicircular canals for rotation detection and two otolith organs for linear acceleration detection. Whereas Unilateral Centrifugation (UC) [1] is used for over a decade to evaluate the utricle, the ocular vestibular evoked myogenic potential (oVEMP) test is a very recent test, claiming to be also a utricular test. The...

Vertigo symptoms and subclinical vestibular dysfunctions may occur in migraine. The Minimal Caloric Test (MCT), an easy-to-perform, convenient and yet informative procedure was used to test the vestibular function in 30 vertigo-free migraine patients outside attacks and 30 paired controls. Although not statistically significant, a right-to-left nystagmus duration asymmetry greater than 25% was ...
