General vestibular testing.
A dysfunction of the vestibular system is commonly characterized by a combination of phenomena involving perceptual, ocular motor, postural, and autonomic manifestations: vertigo/dizziness, nystagmus, ataxia, and nausea. These 4 manifestations correlate with different aspects of vestibular function and emanate from different sites within the central nervous system. The diagnosis of vestibular s...
متن کاملA Study on Physical Factors Stimulating the Semicircular Canals Receptors (Cupola)
SUMMARY Although sciences and techniques have been significantly developed, many patients are still suffering from diagnostic and therapeutic problems of vestibular system, specially vertigo. Perhaps, these problems are not solved yet mostly because the neurophysiology of vestibular system and the stimulation mechanisms of the receptors are not known. This difficulty, intum, causes some a mbig...
متن کاملمقایسه نتایج آزمون ویدئویی ایمپالس سر در افراد مبتلا به تومورهای سیستم دهلیزی محیطی و مرکزی
Background and purpose: Vestibular Schwannoma (VS) is a lesion in peripheral vestibular system that leads to reduction of Vestibulo Ocular Reflex (VOR) gain and incidence of corrective saccades. Researches showed that the result of Video Head Impulse Test (VHIT) is positive in peripheral vestibular system disorders and negative in central vestibular system disorders. The aim of this study was t...
متن کاملA trail of artificial vestibular stimulation: electricity, heat, and magnet.
The interaction between the magnetic field of a magnetic resonance imaging (MRI) machine and ion currents within the inner-ear endolymph results in a Lorentz force. This force produces a pressure that pushes on the cupula within the semicircular canals causing nystagmus and vertigo. Here I discuss several implications of this unique and noninvasive way to stimulate the vestibular system in expe...
متن کاملRelative diagnostic value of ocular vestibular evoked potentials and the subjective visual vertical during tilt and eccentric rotation.
OBJECTIVE We compared vibration-induced ocular vestibular evoked myogenic potentials (OVEMPs) with the visual vertical during whole-body roll tilt and eccentric rotation in healthy subjects and patients with unilateral vestibular loss, to determine which test was most sensitive in discriminating impaired utricle function. METHODS OVEMPs and the visual vertical were measured in 11 patients and...
