Head-shaking nystagmus. Head-Shaking Nystagmus (HSN) is a latent spontaneous vestibular nystagmus provoked by rapid passive head shaking around a vertical axis. HSN is not specific in distinguishing peripheral hypofunction from more central vestibular imbalances. This test is an excellent bedside test for detecting unilateral vestibular hypofunction but further rotatory and caloric testing will...
Modern diagnostic methods such as video head impulse test and cervical and ocular vestibular evoked myogenic potentials allow to measure canal and otolith function quantitatively and objectively. These methods contribute to a complex assessment of the functional integrity of all 5 sensory elements of the vestibular organ for the first time. Moreover, in combination with additional vestibular te...
introduction: evaluation of persistent vertigo in post infarct patients is very important as the management depends on whether the cause is purely of central origin or due to associated vestibular affliction. case report: a patient with left sided dorsolateral medullary syndrome and persistent vestibular symptoms was evaluated. vestibular test battery showed abnormal smooth pursuit, bilateral...
Background and Aim: Children need to have appropriate sensory stimulation, sensory stimulation improve motor skills and competence for the children to school. Such as of these stimulations is vestibular stimulation. Many of the educable mentally disability child are the poor motor coordination and balance that some of these children, who are known as developmental coordination disorder (DCD). T...
OBJECTIVES The aim of the study was to assess the usefulness of bedside examination for screening of vestibular and balance system for occupational medicine purposes. Study group comprised 165 patients referred to Audiology and Phoniatric Clinic due to vestibular and/or balance problems. Caloric canal paresis of 19% was the cut off value to divide patients into 43 caloric-positive vestibular su...
Aim of this study was to determine sensitivity and specificity of the mastoid vibration test in patients who had suffered an attack of vestibular neuritis. Results were compared with the caloric test and two bedside tests of vestibular function (head shaking test and head thrust test). Results are reported in 28 patients who had a residual vestibular deficit 6 months after acute neuritis and in...
INTRODUCTION Cochlear implants are undeniably an effective method for the recovery of hearing function in patients with hearing loss. OBJECTIVE To describe the preoperative vestibular assessment protocol in subjects who will be submitted to cochlear implants. METHODS Our institutional protocol provides the vestibular diagnosis through six simple tests: Romberg and Fukuda tests, assessment f...
BACKGROUND Imbalance from degeneration of vestibular end organs is a common problem in the elderly. However, the decline of vestibular function with aging was revealed in few vestibular function tests such as vestibular autorotation test (VAT). In the current VAT, there are drawbacks of poor test-retest reliability, slippage of the sensor at high-speed rotations, and limited data about the effe...
OBJECTIVE The aim of this study is to show sensitivity and specificity of cervical vestibular-evoked myogenic potential (cVEMP) tuning property test to Ménière's disease (MD) in comparison with healthy controls (HC) and patients with other vestibular diseases. SUBJECTS Totally 92 subjects (50 women and 42 men, 20-77 years of age) were enrolled in this study. Subjects were composed of 38 defin...
Audiological and vestibular testing plays an important role in diagnosis of Menière’s disease,as disease per se and as staging diagnosis. A battery of tests are recommended in order to have a better evaluation of the disease. Audiological testing includes pure tone audiometry, with highlights of bone conduction especially in acute episodes of Menière’s disease, speech audiometry and glycerol te...
