Vestibular reflexes in humans can be assessed by means of acoustically evoked responses of myogenic origin. For the vestibular-collic pathway this is termed the vestibular evoked myogenic potential (or VEMP) and for the vestibular-ocular pathway the ocular VEMP (or OVEMP). Usually VEMPs require an averaging process to obtain a clear response against the background myogenic activity, but dependi...

Todd et al. (2014) have recently demonstrated the presence of vestibular dependent changes both in the morphology and in the intensity dependence of auditory evoked potentials (AEPs) when passing through the vestibular threshold as determined by vestibular evoked myogenic potentials (VEMPs). In this paper we extend this work by comparing left vs. right ear stimulation and by conducting a source...

OBJECTIVES To investigate the clinical utility of VEMPs in patients suffering from unilateral vestibular schwannoma (VS) and to determine the optimal stimulation parameter (air conducted sound, bone conducted vibration) for evaluating the function of the vestibular nerve. METHODS Data were obtained in 63 patients with non-operated VS, and 20 patients operated on VS. Vestibular function was as...

The patho-physiology of inner ear is an intriguing entity, which is yet to be understood in its full entirety. It is an interesting phenomenon to explore the way in which the labyrinth responds to various insults with a myriad of presentations manifesting clinically. Otologists have long wondered for a reasonable explanation as to why Stapedotomy patients may develop intense post-operative vert...

wind speed is one of the characteristics of wind energy which its data is extracted from meteorological stations. in this study, the data obtained from the weather station in the city eqlid during a ten-year period has been used. weibull distribution was chosen as the best distribution function using fitting tests and estimation of some statistical parameters. the results showed that the averag...

background and aim: vestibular migraine is a type of migraine that causes vertigo, dizziness, and imbalance in addition to typical migraine symptoms. in this study, we aimed to investigate vestibular system in these patients by videonystagmography (vng), electrocochleography (ecochg), and vestibular evoked myogenic potential (vemp) testing. methods: this empirical study was conducted on 10 pati...
