Dizziness and imbalance are the most common complaints in older people, a growing public health concern. Although causes of dizziness people multifactorial, peripheral vestibular dysfunction is one frequent causes. Every factor associated with maintenance postural stability deteriorates aging. Age-related deterioration function has been demonstrated through quantitative measurements vide head i...

Objectives: This study was performed to evaluate the difference of cervical vestibular evoked myogenic potentials (cVEMP) stimulated by bone-conduction (BC) and air-conduction (AC) in patients with nonspecific dizziness.Methods: Twenty-eight dizzy (56 ears) 15 subjects (30 as normal control enrolled. Responses BC- AC-cVEMP were recorded sequentially both groups. cVEMP parameters including laten...

BACKGROUND The probable cause of Benign Paroxysmal Positional Vertigo (BPPV) is a degeneration of the oto lithic organs (utricle and saccule). The aim of the study is to find possible alterations in Vestibular Evoked Myogenic Potentials (VEMP) recordings in BPPV patients, because the saccule is part of the VEMP pathway. MATERIAL/METHODS 27 BPPV patients (24 unilateral and 3 bilateral) aged 20...

OBJECTIVES This study aims to examine the effects of dental implant surgery on vestibular-evoked myogenic potential (VEMP) responses. PATIENTS AND METHODS Between October 2012 and October 2014, a total of 60 consecutive patients undergoing dental implant surgery at Başkent University Hospital, Department of Otorhinolaryngology were included in the study. The control group consisted of 40 heal...

OBJECTIVES/HYPOTHESIS This study investigated the development of otolithic-ocular reflex in small children (<3 years old) via the ocular vestibular-evoked myogenic potential (oVEMP) test. STUDY DESIGN Prospective study. METHODS Twenty full-term newborns (group A), 15 children aged 1 to 3 years (group B), and 15 children aged 4 to 13 years (group C) were enrolled in this study. All children ...

BACKGROUND The medial vestibulospinal tract (MVST), which descends in the medial longitudinal fasciculus (MLF), may mediate the vestibular evoked myogenic potentials (VEMPs) in the contracting sternocleidomastoid muscle. We report herein abnormal VEMPs in a patient with medial medullary infarction (MMI) that appeared to involve the MLF. CASE REPORT A patient with infarction involving the righ...

OBJECTIVES To evaluate the use of 75 auditory clicks rather than the usual 100-256 for production of the vestibular-evoked myogenic potential (VEMP) response and to assess if the VEMP correlates with measures of cochlear function such as hearing loss (decibels on pure-tone testing) or auditory brainstem response (ABR). SUBJECTS AND METHODS Testing of the VEMP was carried out on 24 subjects: 7...

Electromyograms (EMGs) were recorded from surface electrodes over the sternomastoid muscles and averaged in response to brief (0.1 ms) clicks played through headphones. In normal subjects, clicks 85 to 100 dB above our reference (45 dB SPL: close to perceptual threshold for normal subjects for such clicks) evoked reproducible changes in the averaged EMG beginning at a mean latency of 8.2 ms. Th...
