“…Recently, this stimulus was reported to provide larger n1-p1 amplitudes in oVEMPs than with TBs at a frequency of 500 Hz by air conduction in healthy subjects (Mat et al 2021). Two other studies confirmed this observation on oVEMPs by bone and air conduction at 500 Hz (Karaçaylı et al 2020;Çoban et al 2021). Regarding cVEMPs, the advantage of using NB CE-Chirps over TBs is unclear.…”

“…It has already been reported in cVEMPs and oVEMPs. It is probably induced by the presentation time of NB CE-Chirps which is always earlier than for TBs ( Wang et al 2014 ; Karaçayli et al 2020 ; Çoban et al 2021 ; Mat et al 2021 ; Ocal et al 2021 ). It has also been suggested that primary vestibular neurons may have double or triple firing to one TB and the latencies of VEMPs responses might be delayed to this second or third spikes, unlike NB CE-Chirps ( Cheng and Murofushi 2001a ).…”

Objectives: To compare the effects of Narrow band CE-Chirps (NB CE-Chirps) and tone bursts (TBs) at 500 Hz and 1000 Hz on the amplitudes and latencies in cervical vestibular evoked myogenic potentials (cVEMPs).Design: Thirty-one healthy adult volunteers of varying ages were tested by air conduction at 95 dB nHL. Recording conditions were randomized for each participant and each modality was tested twice.Results: NB CE-Chirps showed larger corrected amplitudes than TBs at 500 Hz (p < 0.001) which were themselves larger than NB CE-Chirps and TBs at 1000 Hz (p < 0.001). In older volunteers, NB CE-Chirps 500 and 1000 Hz had significantly higher response rates than TBs 500 Hz (p = 0.039). A negative correlation was observed between the corrected amplitudes and the age of the participants regardless of the stimulus and the frequency studied. The p13 and n23 latencies were not correlated with the age of the subjects.Conclusions: NB CE-Chirps at 500 Hz improved the corrected amplitudes of waveforms in cVEMPs as a result of a better frequency specificity compared with TBs. In the elderly, eliciting cVEMPs at a frequency of 1000 Hz might not be necessary to improve response rates with NB CE-Chirps. Additional studies including a higher number of healthy participants and patients with vestibular disorders are required to confirm these observations.

“… 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 ). The duration of 500 Hz tone burst stimulus is relatively longer than that of clicks and chirps stimuli; saccule and the vestibular nerves are hypothesized to respond effectively when stimulated using a long-duration stimulus ( Cheng et al, 2003 ; Wu et al, 2007 ; Singh and Apeksha, 2014 ).…”

“…For each ear, sound stimuli generated were Narrow Band CE-Chirps (NB CE-Chirps) at the intensity level of 100 dB nHL (normalized hearing level; corresponding to 125,5 dB peak SPL) at the frequency of 500 Hz. NB CE-chirps were chosen because they showed larger amplitudes values in oVEMPs and cVEMPS than Tone Bursts at the frequency of 500 Hz on healthy subjects (14)(15)(16)(17)(18). The duration of the NB CE-Chirps was 9 ms for 500 Hz (range 360-720 Hz).…”

Objective: To compare ocular vestibular evoked myogenic potentials (oVEMPs) obtained with three different electrode montages (infra-orbital vs belly-tendon vs chin) in a group of healthy subjects. To assess the electrical activity recorded at the level of the reference electrode in the belly-tendon and chin montages. Study Design: Prospective study. Setting: Tertiary referral center. Patients: Twenty-five healthy adult volunteers. Intervention(s): Each ear was tested separately via air-conducted sound (500 Hz Narrow Band CE-Chirps at 100 dB nHL) for recording contralateral myogenic responses. Recording conditions were randomized. Main Outcome Measure(s): n1-p1 amplitudes values, interaural amplitude asymmetry ratios (ARs) and response rates. Results: The belly-tendon electrode montage (BTEM) produced larger amplitudes than the chin ( p = 0.008) and the IOEM (infra-orbital electrode montage; p < 0.001). The chin montage displayed larger amplitudes than the IOEM ( p < 0.001). The interaural amplitude asymmetry ratios (ARs) were not affected by the different electrode montages ( p = 0.549). In 100% of cases, oVEMPs were detected bilaterally with the BTEM which is higher than with the chin and the IOEM ( p < 0.001; p = 0.020, respectively). We did not record any VEMP when placing the active electrode on the contralateral internal canthus or the chin and the reference electrode on the dorsum of the hand. Conclusions: The BTEM increased the amplitudes recorded and response rate in healthy subjects. No positive or negative reference contamination was observed with the belly-tendon or chin montages.
