“…Although earlier studies have compared P1N1 amplitudes of the cVEMPs across single or two frequencies, 8,14,15 the present study is the initial one to compare cVEMPs over four octaves as often suggested in the literature. 16,17,18 Though the findings of the present study were consistent with the study by Özgür et al 26 and Ocal et al 8 it rejected the claim by some other studies. 14,15,24 Wang et al 24 published the first report of CE-chirp eliciting a significantly greater amplitude than 500 Hz tone bursts.…”

“…8,14,15,24 However, the amplitude of NB CE-chirp evoked VEMPs remain equivocal as several researchers have reported significantly higher amplitude responses than tone bursts 14,15,24 while others have rejected the claim. 8,26 Therefore, in the present study, we attempted to compare the effects of NB CE-chirps and tone bursts on cVEMPs at four different octave frequencies in younger adults.…”

Background: Cervical Vestibular Evoked Myogenic Potentials (cVEMPs) are inhibitory myogenic responses that have commonly been elicited using a variety of stimuli. Yet, the comparison of the effects of multi-frequency tone bursts and narrowband Claus Elberling chirps (NB CE-chirps) on cVEMPs has never been studied in homogeneous age groups. Purpose: The present study focused on comparing the effect of multi-frequency NB CE-chirps and tone bursts on the various parameters of cVEMP responses in normal-hearing younger adults. Research Design: A within-group study design was applied, and purposive sampling was utilized for the collection of the data sample. Study Sample: The present study involved the elicitation of NB CE-chirps and tone bursts evoked cVEMPs across four-octave frequencies in 25 normal-hearing younger adults. Results: NB CE-chirps and tone bursts evoked cVEMPs were found to have a 100% response rate for all frequencies except 4000 Hz. Across frequencies, P1 and N1 latencies were seen to be significantly shorter for NB CE-chirps than tone bursts at 500 Hz and 1000 Hz stimulation. No differences were seen in the P1N1 amplitudes and inter-aural asymmetry ratio (IAAR) between the two stimuli across all four-octave frequencies. Further, it was found to have a significantly higher number of ears tuned to NB CE-chirps than tone bursts at 500 Hz. Conclusions: Comparative differences in the latencies of cVEMP responses between and within stimuli could be due to the variation in stimuli duration. Also, the difference in amplitudes across stimulation frequencies might have resulted due to the predominance of saccular responses at lower mechanical resonance frequencies. Thus, the tuning was also seen at 500 Hz and was relatively higher for NB CE-chirps than tone bursts.

Background: It is ascertained that the compressed high-intensity radar pulse (CHIRP) is an effective stimulus in auditory electrophysiology. This study aims to investigate whether Narrow Band Level Specific Claus Elberling Compressed High-Intensity Radar Pulse (NB LS CE-CHIRP) stimulus is an effective stimulus in the vestibular evoked myogenic potentials test. Methods: A case-control study was designed. Fifty-four healthy participants with no vertigo complaints and 50 patients diagnosed with acute peripheral vestibular pathology were enrolled in this study. Cervical and ocular vestibular evoked myogenic potential tests (cervical vestibular evoked myogenic potentials and ocular vestibular evoked myogenic potentials) with 500 Hz tone burst and 500 Hz Narrow Band Level Specific CE-CHIRP stimulations were performed on all participants. In addition, cervical vestibular evoked myogenic potentials and ocular vestibular evoked myogenic potentials tests with 1000 Hz tone burst and 1000 Hz Narrow Band Level Specific CE-CHIRP were performed on 24 Meniere’s disease patients. P1 latency, N1 latency, amplitude, threshold, and the asymmetry ratio of responses were recorded. Results: In healthy participants, with CHIRP stimulus, shorter P1 latency ( P < .001), shorter N1 latency ( P < .001), and lower threshold ( P = .003) were obtained in the cervical vestibular evoked myogenic potentials test; shorter P1 latency ( P < .001), shorter N1 latency ( P < .001), higher amplitude ( P < .001), and lower threshold ( P < .001) were obtained in ocular vestibular evoked myogenic potentials test. In symptomatic ears of patients, with CHIRP stimulus, shorter P1 latency ( P < .001), shorter N1 latency ( P < .001), and lower threshold ( P = .013 in cervical vestibular evoked myogenic potentials; P = .015 in ocular vestibular evoked myogenic potentials) were obtained in cervical vestibular evoked myogenic potentials and ocular vestibular evoked myogenic potentials tests. In asymptomatic ears of patients, with CHIRP stimulus, shorter P1 latency ( P < .001) and shorter N1 latency ( P < .001) were obtained in the cervical vestibular evoked myogenic potentials test; shorter P1 latency ( P < .001), shorter N1 latency ( P < .001), higher amplitude ( P < .001), and lower threshold ( P = .006) were obtained in ocular vestibular evoked myogenic potentials test. Conclusion: Our results suggest that due to higher response rates, shorter latencies, higher amplitude, and lower threshold values, the Narr...

“…The earlier studies have used chirps of different bands-200-10,000Hz by Wang et al (6); 500-4000Hz by Özgür et al (7) and 250-1000Hz by Walther et al (8). All these studies compared the c-VEMP responses of chirp with clicks and 500 Hz tone bursts.…”

The Cervical-Vestibular evoked Myogenic potential(c-VEMP) is a biphasic surface potential recorded from the belly of Sternocleidomastoid muscle (SCM) followed by presenting a short loud sound. Various studies have been done with different stimulus to obtain better VEMP responses. The present study is aimed at comparing the c-VEMP responses (amplitude and latencies) of 500 Hz tone burst with 500Hz octave chirp (360-720Hz). c-VEMP was administered on 60 ears from 30 subjects. After preparation, responses were recorded presenting 500Hz Tone bursts and 500Hz octave chirps. P1-N1 amplitude, P1 and N1 latencies for both stimuli were noted. The chirp was observed to produce significantly larger amplitude and early latencies than tone burst (p<0.01). This study was in search of a stimulus that will produce larger and better response to be used in clinics , Chirp qualifies to be one. Further studies on larger sample size and age groups are required to make generalizations.
