Differing response properties of cervical and ocular vestibular evoked myogenic potentials evoked by air-conducted stimulation
OBJECTIVE To determine the amplitude changes of vestibular evoked myogenic potentials (VEMPs) recorded simultaneously from the neck (cVEMPs) and eyes (oVEMPs) in response to 500 Hz, 2 ms air-conducted sound pips over a 30 dB range. METHODS Fifteen healthy volunteers (mean age 29, range 18-57 years old) and one patient with unilateral superior canal dehiscence (SCD) were studied. The stimulus ...
متن کاملCervical and ocular vestibular evoked myogenic potentials in multiple sclerosis participants
Background: Multiple sclerosis (MS) is a chronic neurological disease that affects brain and spinal cord. The infratentorial region contains the cerebellum and brainstem. Vestibular evoked myogenic potentials (VEMPs) are short-latency myogenic responses. Cervical vestibular evoked myogenic potential (cVEMP) is a manifestation of vestibulocolic reflex and ocular vestibular evoked myogenic pote...
متن کاملVestibular evoked myogenic potentials (VEMPs) evoked by air- and bone-conducted stimuli in vestibular neuritis
OBJECTIVE To compare and characterise abnormalities for short latency vestibular evoked myogenic potentials (VEMPs) elicited by air- (AC) and two differing types of bone-conducted (BC) stimuli during vestibular neuritis (VN). METHODS AC (500Hz short tone bursts) and two BC stimuli (500Hz at the forehead and impulses at the mastoids) were used to evoke cervical and ocular potentials (cVEMPs an...
متن کاملOcular Vestibular Evoked Myogenic Potentials
Introduction Diagnostic testing of the vestibular system is an essential component of treating patients with balance dysfunction. Until recently, testing methods primarily evaluated the integrity of the horizontal semicircular canal, which is only a portion of the vestibular system. Recent advances in technology have afforded clinicians the ability to assess otolith function through vestibular ...
متن کاملOcular vestibular evoked myogenic potentials in response to air conducted stimuli: clinical application in healthy adults.
OBJECTIVES This study aims to determine the normal values for ocular vestibular evoked myogenic potentials in response to air conducted stimuli in healthy adults. PATIENTS AND METHODS Thirty-six healthy adult participants with no ear complaints were enrolled. Ocular vestibular evoked myogenic potential tests were performed to all participants. Latency and amplitude values of the waves were re...
