“…Affected cVEMP responses in the asymptomatic ears of individuals were also reported previously [47][48][49]. The postmortem studies on the temporal bones of individuals with Meniere's disease demonstrated the presence of saccular hydrops in nearly 35% of the asymptomatic ears [50], which further substantiates the findings of the present study.…”

“…However, an inherent constraint in the recording of CHAMP arises from the use of only 60 dB nHL for click intensity. It is well known that the nHL thresholds obtained using the auditory brainstem response to clicks are 10 to 20 dB higher than the behavioral auditory thresholds in HL [47,57]. This would mean that for losses exceeding moderate degree, an auditory brainstem response to 60 dB nHL clicks would be absent since ABR thresholds for clicks have been reported to be 10-20 dB higher than the actual behavioral threshold.…”

“…Thus CHAMP would appear to be useful only up to a moderate degree of hearing loss. On the contrary, the degree of sensorineural hearing loss does not impact the VEMP responses in anyway [47]. Therefore, it would be useful for evaluating patients of Meniere's disease with any degree of hearing loss.…”

Cervical vestibular evoked myogenic potential (cVEMP) and cochlear hydrops analysis masking procedure (CHAMP) have both shown sensitivity in identifying Meniere's disease. However none of the previous reports have compared the two tests for their relative efficacy in identifying Meniere's disease. Hence the present study aimed to compare the efficiency of cVEMP and CHAMP in evaluating Meniere's disease. The study included 58 individuals with unilateral definite Meniere's disease and an equal number of age and gender matched healthy individuals. cVEMP corresponding to 500 Hz tone burst was recorded from ipsilateral sternocleidomastoid muscle and CHAMP was acquired from the conventional electrode sites for single channel auditory brainstem response recording using a default protocol of the Biologic Navigator Pro evoked potential system. Both cVEMP and CHAMP showed statistically significant differences between the groups ( < 0.05). The receiver operating curves revealed 100% sensitivity and specificity for CHAMP as against 70.7% sensitivity and 100% specificity for cVEMP in identifying Meniere's disease. Therefore, CHAMP appears to be the test of choice provided the degree of hearing loss does not exceed a moderate degree. cVEMP could be used for all degrees of hearing losses, but with slight constraint on the sensitivity.

“…Although the reasons for such changes in vHIT within or beyond the five days interval are not quite clear, they might be a plausible explanation. Furthermore, such findings in the unaffected ears could be possible because of the ''latent'' or ''occult'' MD in the unaffected ears, which has been reported using a number of tests including cervical vestibular evoked myogenic potentials (cVEMP) (Ribeiro et al, 2005;Lin et al, 2006;Fouly et al, 2012), electrocohleography (Visu and Singh, 2012), and oto-acoustic emissions (Magliulo et al, 2004) previously. The discrepancy among sessions was also observed in two cases with BPPV, one unilateral, and one bilateral.…”

Test–Retest Reliability of Video Head Impulse Test in Healthy Individuals and Individuals with Dizziness

Video head impulse test (vHIT) is widely accepted as a test for the assessment of functional integrity of semicircular canals (SCCs). It allows for the evaluation of the functioning of all six SCCs independent of each other. It works on the principle of the vestibulo-ocular reflex (VOR). In individuals with vestibular pathologies, the VOR is impaired, and hence, the use of vHIT may provide vital information about the functional status of SCCs and the VOR pathway originating from them.In the recent past, studies reported excellent test–retest reliability of vHIT in healthy individuals. However, these studies used analysis of variance or the nonparametric counterpart Wilcoxon signed-rank test, which are insufficient statistical methods for conclusions about test–retest reliability. Further, because vHIT assesses VOR function in individuals with vestibular pathologies, it is important to assess test–retest reliability in the pathological group as well. Therefore, the present study aimed to evaluate test–retest reliability of vHIT in healthy individuals and individuals with vestibular pathology.Repeated measures.Twenty healthy individuals with no history of vestibular pathology and 20 individuals with known vestibular pathology were included.Each participant underwent vHIT testing for all three SCCs of both sides on four different occasions. VOR gain and the presence of pathological saccades were noted and analyzed for each recording.Intraclass correlation coefficient (ICC) revealed excellent test–retest reliability for VOR gain in both groups (ICC ≥ 0.76). Kappa coefficient analysis for the presence of refixation saccades demonstrated moderate to excellent agreement between test sessions (K ≥ 0.63) for the lateral canal. For the anterior and posterior SCC, there was large variability between sessions for refixation saccades.This study provides evidence about test–retest reliability of VOR gain and refixation saccades assessed using vHIT in healthy individuals and individuals with vestibulopathies. These findings suggest that both measures are highly reliable and replicable across test sessions, except refixation saccades in vertical canals which varied between sessions in some individuals.

“…The previous studies in this regard did not attempt to compare the individual participant's frequency tuning data between the groups (Sandhu et al, 2012;Winters et al, 2012;Jerin et al, 2014). Nonetheless, the finding of higher proportion of unaffected ears showing frequency tuning at 1000 Hz than the healthy controls could be due to the existence of the "occult" or "latent" endolymphatic hydrops in the unaffected ear which was shown previously through the use of tests like cVEMP (Ribeiro et al, 2005;Lin et al, 2006;Fouly et al, 2012), electrocochleography (Visu and Singh, 2012), oto-acoustic emissions (Magliulo et al, 2004), and postmortem studies (Tsuji et al, 2000).…”
