This study investigated the effect of eye gaze and head position on vestibular-evoked potentials (VsEPs). Head position would be expected to affect myogenic sources, and eye position is known to affect ocular myogenic responses (ocular vestibular-evoked myogenic potentials), whereas a neurogenic source should behave otherwise. Eleven healthy subjects were recruited, and VsEPs, using 72-channel ...

OBJECTIVE To use a combination of electrophysiological techniques to determine the extent of preserved muscle activity below the clinically-defined level of motor-complete spinal cord injury. METHODS Transcranial magnetic stimulation and vestibular-evoked myogenic potentials were used to investigate whether there was any preserved muscle activity in trunk, hip and leg muscles of 16 individual...

background and aim: caffeine at low doses blocks adenosine receptors. these receptors are present in all parts of the body including auditory and vestibular system. this study aimed to evaluate the effects of caffeine on cervical vestibular evoked myogenic potential (cvemp). methods: in this interventional double-blind study, 40 cases (20 females and 20 males) aged 18-25 years were randomly ass...

Meniere’s disease is a disorder of the inner ear resulting in symptoms episodic vertigo, tinnitus, hearing loss and aural pressure. Although exact etiology uncertain, it associated with raised pressure endolymph (endolymphatic hydrops). The diagnosis Meniere's based on clinical setting patient. This usually presents unilateral but can be also bilateral. attacks are random (approximately 6-11 pe...
