Abstract Background Masseter vestibular evoked myogenic potential (mVEMP) is a recent tool for the assessment of and trigeminal pathways. Though few studies have recorded mVEMP using click stimuli, there are no reports these potentials more conventional VEMP eliciting tone bursts. Purpose The aim study to establish normative values determine test–retest reliability burst mVEMP. Research Design research design type design. Study Sample Forty-four healthy participants without hearing deficits...
Objective The present study aimed to investigate the findings of cervical, ocular and masseter vestibular evoked myogenic potentials (cVEMP, oVEMP mVEMP) among Multiple sclerosis (MS) correlate with clinical MRI findings.Design Standard group comparison research designStudy sample Individuals relapsing-remitting MS (n = 45) age-sex-matched controls were participants. All them underwent case history, neurological examination, cVEMP, mVEMP testing. was obtained only for participants.Results...
Benign paroxysmal positional vertigo (BPPV) is a unilateral peripheral vestibular pathology, mostly involving the semicircular canals and otolith organs. Although equivocal findings exist on utility of cervical vestibular-evoked myogenic potential in identifying BPPV-associated changes saccule, ocular (oVEMP), which primarily utricular response, has sparingly been explored this population. Hence, present study aimed at examining oVEMP individuals with BPPV comparing them healthy to...
Several parameters of ocular vestibular-evoked myogenic potential (oVEMP) have been used to identify Meniere's disease. Nonetheless frequency-amplitude ratio (FAR), which is the amplitude between two frequencies, one among that has failed attract researchers' attention despite proving its worth in diagnosis disease when conjunction with cervical VEMP. Thus, present study aimed at investigating utility FAR oVEMP identifying and finding out an optimum frequency pair for diagnosis.Using a...
Objective: Inconsistencies regarding frequency tuning of ocular vestibular evoked myogenic potentials (oVEMP) prompted the present study to aim at characterizing oVEMP in healthy individuals. Design: Normative study. Study sample: The was conducted obtain responses from 54 individuals age range 18–30 years. were acquired for tone-bursts octave and mid-octave frequencies 250 2000 Hz inferior oblique muscle using contralateral electrode placement. compared amplitude threshold. Results: oVEMPs...
Video head impulse test (vHIT) is widely accepted as a for the assessment of functional integrity semicircular canals (SCCs). It allows evaluation functioning all six SCCs independent each other. works on principle vestibulo-ocular reflex (VOR). In individuals with vestibular pathologies, VOR impaired, and hence, use vHIT may provide vital information about status pathway originating from them.In recent past, studies reported excellent test-retest reliability in healthy individuals. However,...
The involvement of otolith organs in motion sickness has long been debated; however, equivocal findings exist literature. present study thus aimed at evaluating the functioning individuals with sickness. Cervical and ocular vestibular evoked myogenic potentials were recorded from 30 sickness, professional drivers healthy individuals. results revealed no significant difference latencies amplitudes between groups (p>0.05). Nonetheless, thresholds significantly elevated inter-aural asymmetry...
The normal process of aging is mostly associated with global decline in almost all sensory aspects the human body. While affects 500-Hz tone burst-evoked ocular vestibular-evoked myogenic potentials (oVEMPs) by reducing amplitudes and prolonging latencies, its interaction oVEMP responses at other frequencies has not been studied. Therefore, present study aimed investigating impact advancing age on frequency tuning oVEMP.Using a cross-sectional research design, oVEMPs were recorded for burst...
Amidst several publications reporting the effects of stimulus-related parameters on ocular vestibular evoked myogenic potential (oVEMP), effect repetition rate oVEMP responses has largely gone unexplored. Studies have used a ~5.1 Hz mainly due to presumption that oVEMP, like cervical VEMP, should produce best for ~5 Hz, although there is paucity experimental evidence support this hypothesis. 52 healthy individuals in age range 17-35 years underwent air-conduction elicited by 500 tone-bursts...
Utility of frequency tuning ocular vestibular evoked myogenic potential (oVEMP) for evaluation utricular function in individuals with Meniere's disease is a recent development. However, there dearth studies regarding its utility differential diagnosis from other pathologies.The present study aimed at investigating the feasibility oVEMP discriminating benign paroxysmal positional vertigo (BPPV).Static group comparison.oVEMPs were acquired 36 individuals, each unilateral and BPPV. Thirty-six...
Literature on clinical utility of cervical vestibular-evoked myogenic potential (cVEMP) has been increasing rapidly, though not without inconsistencies in spite involving similar populations. Close examination methods across studies exposed the use variable stimulus parameters, especially rise/fall time (R/FT) and plateau (PT) as possible reason. However effect variation R/FT PT cVEMP response parameters largely uncharted.The study aimed at evaluating impact cVEMPs elicited by 500-Hz short...
Cervical vestibular evoked myogenic potential (cVEMP) is a biphasic recorded from the Sternocleidomastoid muscle in response to loud acoustic stimulation and assesses intactness of Sacculocolic pathway. The literature on clinical utility cVEMP has been growing rapidly, though not without inconsistencies despite involving alike population. A close scrutiny methods across such studies revealed an inconsistent use stimulus parameters; especially rise/fall times (RFTs). However effect RFTs...
Auditory neuropathy is characterized by a unique pattern of hearing loss, absent or severely distorted ABR, preserved OAE, and measurable cochlear microphonics. As the vestibular branches are parts same fiber bundle system called vestibulocochlear nerve, it likely that in one (cochlear branch) might also form feature other (vestibular branch). But none these tests able to explain involvement cases. Thus, present study was undertaken explore this aspect determine: (1) pathway cases with...
Objective: This study aimed to correct the notion regarding efficacy of cervical vestibular evoked myogenic potentials (cVEMP) in identifying benign paroxysmal positional vertigo (BPPV)-associated changes peripheral system. Study design: A static group comparison research design was used compare cVEMP results a individuals with BPPV age range 30–60 years against age- and gender-matched healthy individuals. The were recorded tone bursts 500 Hz gated using Blackman window. 95dB nHL presented...
