OBJECTIVES/HYPOTHESIS To determine if vestibular potentials could be elicited with electrical stimulation from cochlear implants. STUDY DESIGN Prospective cohort study. METHODS Vestibular responsiveness to electrical stimulation from cochlear implants was assessed via vestibular evoked myogenic potential (VEMP) testing in 53 pediatric and young adult patients. RESULTS Thirty-one participa...

Small electrodynamic shakers are becoming increasingly popular for diagnostic investigations of the human vestibular system. More specifically, they are used as mechanical stimulators for eliciting a vestibular evoked myogenic potential (VEMP). However, it is largely unknown how shakers perform under typical measurement conditions, which considerably differ from the normal use of a shaker. Here...

We investigated how vestibulo-spinal reflexes (VSRs) and vestibulo-ocular reflexes (VORs) measured through vestibular evoked myogenic potentials (VEMPs) and video head impulse test (vHIT) outcomes, respectively, are modulated during standing under conditions of increased postural threat. Twenty-five healthy young adults stood quietly at low (0.8 m from the ground) and high (3.2 m) surface heigh...

Vestibular involvements have long been observed in otosclerotic patients. Among vestibular structures saccule has the closest anatomical proximity to the sclerotic foci, so it is the most prone vestibular structure to be affected during the otosclerosis process. The aim of this study was to investigate the saccular function in patients suffering from otosclerosis, by means of Vestibular Evoked ...

INTRODUCTION A considerable high number of SNHL patients also suffer from dizziness and related vestibular symptoms. OBJECTIVE To evaluate the association of vestibular dysfunction and sensorineural hearing loss (SNHL) in adult patients. METHODS Prospective, double-blinded, controlled studies composed by 63 adult patients without any vestibular symptoms or diagnosed vestibular diseases. Aud...

Recebido em 27.03.2008. Revisado em 15.06.2008; 29.07.2008. Aceito para Publicação em 21.10.2008. Abstract Background: the Vestibular Evoked Myogenic Potential (Vemp) is formed by myogenic neurophysiologic responses activated by high-intensity sound stimulation. The response is registered through surface electromyography of the cervical muscles during muscle contraction. The acoustic stimuli ac...

Métodos Estudo longitudinal, quase experimental analítico, realizado entre dezembro de 2019 julho 2022, com 50 idosos disfunção ve...

Objectives: Inferior oblique muscle overaction (IOOA) is a common ocular motility disorder. Ocular Vestibular Evoked Myogenic Potentials (oVEMP) are tests that evaluate the reflex pathway between utricular macula and inferior to detect vestibular diseases. Our study of great importance as it first in literature effect on oVEMP parameters. Methods: Thirty-five patients with unilateral (IOOA grou...
