Amidst several publications reporting the effects of stimulus-related parameters on ocular vestibular evoked myogenic potential (oVEMP), the effect of the repetition rate on oVEMP responses has largely gone unexplored. Studies have used a repetition rate of ~5.1 Hz mainly due to a presumption that oVEMP, like cervical VEMP, should produce best responses for ~5 Hz, although there is paucity of e...

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 ...

There are differences in the recording methods for cVEMP used across institutions. However, impact of head and body positions on results testing is yet to be determined patients with dysequilibrium. We assessed effects three recordings results, demonstrated advantages disadvantages each position. Three were recordings; A. supine/head rotated; B. semi-recumbent/head rotated elevated; C. elevated...

INTRODUCTION Otosclerosis one of the most common causes of conductive hearing loss is more common in females and in their middle ages. It is usually a bilateral and progressive disease. Surgical operation is suggested as the exclusive management of otosclerosis. This study aims to evaluate the hearing results after stapedectomy in otosclerotic patients in Ahwaz. MATERIALS AND METHODS In this ...

UNLABELLED The vestibular evoked myogenic potential (VEMP) is a clinical test that assess the vestibular function by means of an inhibitory vestibulo-neck reflex, recorded in body muscles in response to high intensity acoustic stimuli. AIM To check and analyze the different methods used to record VEMPs in humans and in guinea pigs. MATERIALS AND METHODS We researched the following databases...

OBJECTIVE The ocular vestibular-evoked myogenic potential (oVEMP), a recently documented otolith-ocular reflex, is considered to reflect the central projections of the primary otolithic afferent fibers to the oculomotor nuclei. The aim of our study is to define air-conducted sound oVEMP abnormality in patients with acute brainstem lesions and to determine the brainstem structures involved in th...

diabetes mellitus type ι is a metabolic disorder that affects multiple systems including the inner ear. patients with diabetes mellitus commonly complain about dizziness, floating sensation, tinnitus and sweating. the aim of this study was to compare vestibular evoked myogenic potentials (vemps) between diabetic patients with or without neuropathy. subjects included 14 patients with diabetes me...

Background The vestibular system interacts with various cognitive functions, including spatial navigation processes, perception, body representation, mental images, attention, memory, risk perception and social cognition. Studies inform that impairment is an important factor for changes in motor performance balance. Method Cross-sectional, observational analytical study. sample consisted of 38 ...
