Comparison of Chirp Versus Tone Burst– and Click-Evoked Masseteric Vestibular Evoked Myogenic Potentials in Normal-Hearing Adults

Abstract

Purpose: This study aimed at comparing narrowband Claus Elberling level-specific chirp (NB CE-Chirp)–, click-, and tone burst–evoked masseteric vestibular evoked myogenic potentials (mVEMPs). Method: Within-group study design and purposive sampling were performed. A total of 25 normal-hearing individuals participated in the study. The zygomatic electrode montage was used to elicit ipsilateral mVEMP responses using a 500-Hz NB CE-Chirp, a click of 100-μs duration, and a 500-Hz tone burst stimulus. Each of the responses was analyzed based on the absolute peak latency of P11 and N21, the electromyography-scaled peak-to-peak amplitude of the P11–N21 complex, and the interaural asymmetry ratio. Results: A total of 50 ears were tested and had 100% mVEMP responses. The latencies of click-evoked and 500-Hz NB CE-Chirp–evoked mVEMPs were significantly shorter than those of 500-Hz tone burst–evoked mVEMPs ( p < .05) for both ears. It revealed a significantly superior P11–N21 amplitude of the 500-Hz NB CE-Chirp and tone burst than clicks for both ears. Intraclass correlation coefficient revealed moderate to excellent test–retest reliability for mVEMP parameters across three different stimulations. Conclusion: The present study supports 500 Hz NB CE-Chirps as effective and reliable stimuli as tone bursts in eliciting mVEMP responses.

Exploring the Relationship between Masseter and Cervical Vestibular-Evoked Myogenic Potentials in Young Adults with Hearing Thresholds Less Than or Equal to 15 dB HL

“…In the study, 100% of the participants had 500 Hz tone burst-evoked mVEMP and cVEMP response parameters. Similar findings have been reported previously for mVEMPs (Vignesh et al 22 ; Vinayagar et al 23 ; Neupane et al 24 )…”

Masseter Vestibular evoked myogenic potentials: A new tool to assess the vestibulomasseteric reflex pathway

“… Neupane et al (2023) reported that the latencies of p11-n21 are shorter when elicited using clicks and 500Hz NB CE-Chirps than compared to those obtained with 500Hz tonebursts. 500Hz NB CE-Chirps tend to have earlier stimulus onset time compared to tonebursts and this could be the reason for the presence of early latencies when chirps were procured ( Çoban et al, 2021 ; Karaçaylı et al, 2020 ; Mat et al, 2021 ).…”

“…Clicks, Chirp and tone-burst stimuli have been primarily used to record mVEMP ( Deriu et al, 2005 , 2007 ; Ginatempo et al, 2013 ; Vignesh et al, 2021 ; Romero et al, 2022 ; Sangu Srinivasan et al, 2022 ; Thirusangu and Sinha, 2022 ; Neupane et al, 2023 ; Vinayagar and Sinha, 2023 ). Vignesh et al (2021) compared the mVEMP responses obtained using tone bursts with that of those obtained with clicks in a study by de Natale et al (2015b) .…”

“…Earlier studies have employed repetition rate of 3Hz to elicit mVEMP ( Deriu et al, 2005 , 2007 ), whereas recent researchers have studied mVEMP responses using 5Hz stimulation rates irrespective of the stimuli used i.e. clicks, chirps or tonebursts ( Kilinc et al, 2023 ; Neupane et al, 2023 ; Vinayagar and Sinha, 2023 ; Xie et al, 2022 ). 5Hz repetition rates have been reported to produce comparatively better morphology and replicability of the waveforms in cervical VEMPs since there is a noticeable intersubject difference in the responses to using higher repetition rates ( Wu et al, 1999 ).…”
