“…Analyzing the male and female populations, we did not find significant differences for p13 and n23 absolute latencies between the right and left ears, which corroborates previous studies, using stimuli at the frequencies of 1,000 Hz 18 , 500 Hz 21 and for click stimuli 22,23 . In the sample studied, we did not find differences between the genders, for all VEMP parameters, as per seen in a previous study 24 , for tone burst stimuli of 250, 500, 750 and 1000 Hz. In other studies (500 Hz tone bursts), there were no reports of changes in VEMP for the absolute latency; nonetheless, we noticed differences in the p13-n23 22,25 amplitudes.…”

“…In our data, we noticed a lower p13 value, the most used parameter in the VEMP analysis 24,27 . For the amplitude parameter analysis, we chose to calculate the asymmetry index, because the absolute amplitude values have very little intra and intersubject reproducibility and are dependent on factors such as age, intensity and frequency of the stimulus and muscle tonus contraction.…”

Vest ibular evoked myogenic potentials are vestibulocervical reflexes resulting from sacculus stimulation with strong intensity sounds. Normality parameters are necessary for young normal individuals, using low frequency stimuli, which configure the most sensitive region of this sensory organ. Aim:To establish vestibular evoked myogenic potential standards for low frequency stimulation.Material and Method: Vestibular evoked myogenic potential was captured from 160 ears, in the ipsilateral sternocleidomastoid muscle, using 200 averaged tone-burst stimuli, at 250 Hz, with an intensity of 95 dB NAn.Case Study: Clinical observational cross-sectional. Results:Neither the student's t-test nor the Mann-Whitney test showed a significant difference in latency or vestibular evoked myogenic potential amplitudes, for p ≤ 0.05. Irrespective of gender, we found latencies of p13-n23 and p13-n23 interpeaks of 13.84 ms (± 1.41), 23.81 ms (±1.99) and 10.62 ms (± 6.56), respectively. Observed values for amplitude asymmetry between the ears were equal to 13.48% for females and 3.81% for males. Conclusion:Low frequency stimuli generate vestibular evoked myogenic potentials, with adequate morphology and amplitude, thereby enabling the establishment of standard values for normal individuals at this frequency.

“…Previous studies have shown that both short tone bursts (STBs) and clicks can evoke myogenic potentials [9], but some studies described that VEMP response is better to clicks than STBs [10], while others have shown that 500 and 750 Hz STBs evoked larger amplitudes compared to 250 Hz STBs and clicks [11,12]. Although the reliability of STB-induced VEMPs has been investigated [13][14][15][16][17], a comparative study of individual responses to STB-and clicks-induced VEMPs in a group of healthy subjects has not been carried out and there is no rationale for using either click or STB.…”

Our aim is to compare short tone burst (STB)--and clicks--stimuli to evoke vestibular-evoked myogenic potentials (VEMPs) in healthy controls. A cross-sectional study in which VEMPs were measured in two sets of 185 and 55 normal volunteers by an air-conducted 500 Hz STBs and clicks, respectively. The test-retest reliability between different sessions was assessed in two subsets of 35 individuals. Moreover, 53 individuals were examined with both stimuli within the same session. Intraclass correlation coefficients (ICC) were used to assess reliability for P1 and N1 latencies, corrected amplitude and asymmetry ratio (AR). The results included that STBs produced a reliable response between different sessions (N = 35; [ICC] = 0.61-0.94, all p < 0.0001). Although clicks produced a reliable response for P1 and N1 latencies and corrected amplitudes (ICC = 0.62-0.74, all p < 0.0001), the amplitude ratio showed a lower reliability [ICC = 0.32 (-0.10 to 0.59)]. The amplitude of VEMP was consistently larger with 500 Hz STBs than clicks for a given sound pressure level. Within the same session, STBs evoked a response in 52/53 subjects (98%) whereas clicks evoked VEMPs only in 44/53 individuals (83%). Conclusions revealed that a 500 Hz STBs elicited consistently larger amplitudes, better reliability across recording sessions and fewer missing responses compared with click-induced VEMPs.

OBJECTIVE:The objective of this study was to explore the usefulness of 1000-Hz tone burst (TB) stimuli for detecting cervical vestibular-evoked myogenic potential (cVEMP) abnormalities in patients with a cochlear implant (CI). MATERIALS and METHODS:Thirty asymptomatic patients who received unilateral CI because of severe bilateral sensorineural hearing loss were assessed for cVEMP produced by TB stimuli at two frequencies (500 and 1000 Hz) in the airway. VEMPs were recorded when the devices were switched to the on (CI-on) and off (CI-off ) positions. RESULTS:At the CI-on position, the surgical side (SS) 500-Hz response rates (15/30) were significantly higher than the SS 1000-Hz response rates (9/30) (p=0.031), while the non-operated control side (CS) 500-Hz response rates (20/30) were higher than the CS 1000-Hz response rates (18/30), but the difference was not significant (p=0.50). At the CI-on position, the SS 500-Hz response rates (15/30) were lower than the CS 500-Hz response rates (20/30), but the difference was not significant (p=0.063). However, the SS 1000-Hz response rates (9/30) were significantly lower than the CS 1000-Hz response rates (18/30) (p=0.004). When there was no significant difference between the 500-Hz amplitudes on either side, the SS 1000-Hz amplitudes were found to be significantly lower (p=0.04). CONCLUSION:CIs have the potential to cause mechanical damage and electrical stimulation to the vestibular system. Possible implant-mediated mechanical damage and electrical stimulation in the high-frequency region affecting the cVEMP response could be found by a 1000-Hz stimulus.
