Tone Burst Masseter Vestibular Evoked Myogenic Potentials: Normative Values and Test–Retest Reliability

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 in age range 18 50 years participated study. Data Collection Analysis All underwent testing 500 Hz tone-burst stimuli at 125 dB peSPL. Ten second within 1 month initial estimate reliability. Results Tone showed robust responses all participants. There were significant ear sex differences on any parameter (p > 0.05); however, males had significantly higher EMG normalized peak-to-peak amplitude than females. Intraclass correlation coefficient (ICC) excellent (ICC >0.75) ipsilateral contralateral p11 latency, p11-n21 peak amplitude, asymmetry ratio. Fair good (0.4 < ICC 0.75) was observed n21 Conclusion reliable test evaluating functional integrity vestibulomasseteric reflex pathway.
