Cervical vestibular evoked myogenic potential (VEMP) is a short-latency myogenic response recorded from the sternocleidomastoid muscle (SCM) in response to saccular stimulation. The currently understood VEMP was first described by Colebatch and Halmagyi and Colebatch et al. [1, . Since then, VEMPs have become a standard clinical test of otolith function [3, 4, 5, 6, 7, . At present, they are of...

INTRODUCTION The vestibular evoked myogenic potential (VEMP) generated by galvanic vestibular stimulation (GVS) is related to the vestibulo-spinal pathway. The response recorded from soleus muscle is biphasic with onset of short latency (SL) component around 60 ms and medium latency (ML) component around 100 ms. The first component reflects otolith function (sacule and utricle) and the last dea...

OBJECTIVE The aim of this study was to determine the roles of magnetic resonance imaging (MRI), auditory evoked potentials (AEP) and vestibular evoked myogenic potentials (VEMP) in the evaluation of brainstem involvement in multiple sclerosis (MS). PATIENTS AND METHODS Altogether 32 patients with the diagnosis of MS participated in the study. The following data was collected from all patients...

OBJECTIVES For a reliable interpretation of left-right difference in Vestibular evoked myogenic potential (VEMP), the amount of sternocleidomastoid muscle (SCM) contraction has to be considered. Therefore, we can ensure that a difference in amplitude between the right and left VEMPs on a patient is due to vestibular abnormality, not due to individual differences of tonic muscle activity, fatigu...

introduction: vestibular evoked myogenic potential (vemp) has recently been broadly studied in vestibular disorders. as it is evoked by loud sound stimulation, even mild conductive hearing loss may affect vemp results. bone-conducted (bc) stimulus is an alternative stimulation for evoking this response. this study aims to assess the characteristics of bc-vemp in different groups of patients.   ...

it has been shown recently that loud clicks evoke myogenic potentials in the tonically contracting sternocleidomastoid muscles. studies have suggested that these potentials are of vestibular origin, especially of the saccule and inferior vestibular nerve. a pilot study was undertaken in our hospital to record vestibular evoked myogenic potentials (vemp) for the first time in iran. eighteen heal...

introduction: sudden sensorineural hearing loss (ssnhl) has a prevalence of 10 in 100,000. viral infections, vascular obstruction and rupture of the intracochlear membranes are supposed to be its most common etiologies. about 40% of patients experience vertigo or imbalance. the vemp (vestibular evoked myogenic potentials) test is a known approach for detailed study of the labyrinth. the advanta...
