Reproducibility (test–retest) of vestibular evoked myogenic potential

Abstract

p13 and n23 latencies and amplitudes of VEMP for tone-burst stimuli at frequencies of 250, 500, and 1000Hz are reproducible.

On the Effectiveness of airborne infrasound in eliciting vestibular-evoked myogenic responses

“…The average p13 and n23 latencies amongst these significant cases were 15.9 ms (SD = 1.6 ms) and 25.9 ms (SD = 2.3 ms), respectively. Both, the average p13-n23 amplitudes and latencies, as well as their SDs, are similar to values reported in the literature for cVEMPs obtained with air-conducted tone bursts 2,39,40 (using linear µV values we obtained a mean amplitude of 74.2 µV (SD = 49.4 µV), which is comparable to the 73.8 µV (SD = 45.5 µV) reported by Basta et al., 39 who proposed normative data for a similar age group and a stimulation level of 115 dB SPL. Their p13 and n23 latencies of 16.2 ms (SD = 2.5 ms) and 24.0 ms (SD = 2.6 ms) are also similar to ours).…”

“…LF/IS cVEMPs. Pure tones of 40,16, and 4 Hz were tested; their levels were set to 112.5, 121 and 132 dB SPL, respectively. These levels were chosen, as they are well above those associated with environmental infrasound, 26,27 and were inspired by the proposed curves by Møller and Pedersen 28 (which were interpolated/extrapolated).…”

“…In each case, measurements started with the right ear and after completing the left ear, the next stimulation type was measured. The order of LF/IS frequencies tested (40,16,4 Hz) was reversed when switching ears. After each single 2 min long recording, subjects were given at least 2 min to relax and gather strength.…”

Assessment of otolith function using vestibular evoked myogenic potential in women during pregnancy

“…The reviews on test-retest reproducibility studies showed that peak to peak amplitude of VEMP responses seems to have good significance. 13 , 14 In the present study, the reduction in peak to peak amplitude of VEMPs in pregnant women may be due to alterations in the otolithic organ, and such alterations in the vestibular system can be attributed to the hormonal milieu changes that occur during pregnancy. Supporting the findings of the present study, there is literature showing that the neurotransmitters released during pregnancy can alter the biochemical control of the inner ear, which possibly triggers an increase in neurotological symptoms.…”

Test-Retest Reliability of Vestibular Evoked Myogenic Potential across Different Age Groups

“…Another study with the feedback method showed excellent reliability for P13 and N23 latencies 6,13 . No significant difference in P13 and N23 latencies across three different sessions for tone burst stimuli 14 . In contrast, studies have reported poor reliability for latencies P13 and fair to good reliability for N23 8,15 .…”
