Amplitude-Modulated Cvemp (Amcvemps) Versus Transient Cvemp Response Properties: Possible Implications, Andrew Thorne

Dissertations, 2020-current

Cervical vestibular evoked myogenic potentials (cVEMPs) elicited by steady-state amplitude-modulated (AM) tones yield different information than conventional cVEMPs elicited by transient tonebursts, such as signal-to-noise ratio (SNR) and phase coherence (PC). This study systematically examined the effects of tonic EMG activation on AMcVEMP response properties versus conventional transient cVEMPs. Thirty five young, healthy adults (ages 19–23) with normal audiograms and no known vestibular lesions participated in this study. AMcVEMPs were elicited with bone-conducted tones with a carrier frequency of 500 Hz and an amplitude modulation frequency of 37 Hz, and transient cVEMPs were elicited by 4-0-4 Blackman-gated 500 Hz tonebursts …
