“…The caloric test (CT), the headshaking test (HST) [ 7 ], and the video-head impulse test (vHIT) refer to low-frequency (≤0.03 Hz), medium-frequency (1–2 Hz), and high-frequency (2–5 Hz) testing of the vestibular semicircular canal, respectively. The vestibular myogenic evoked potential is what is used to evaluate the function of the utricle and saccule.…”

Objective. To analyse the vestibular function characteristics of patients with Meniere's disease and acute hypophonic sensorineural hearing loss in order to find more reliable and objective ancillary tests that will reduce misdiagnosis and missed diagnoses. Methods. From January 2021 to December 2021, 60 healthy adults who underwent physical examination in our hospital were included in the control group, 60 patients with Meniere's disease were included in Study Group A, and 60 patients with acute low-tone sensorineural hearing loss were recruited in Study Group B. All participants underwent the caloric test (CT), video-head impulse test (vHIT), headshaking test (HST), and vestibular-evoked myogenic potential (VEMP) testing, which includes ocular vestibular-evoked myogenic potential (oVEMP) and cervical vestibular-evoked myogenic potential (cVEMP). Results. Statistical analyses of unilateral weakness and directional preponderance (DP) in the two groups of patients found no significant differences between the two groups ( P > 0.05 ). There was no statistically significant difference in the abnormal rate of vHIT and HST results between the two study groups ( P > 0.05 ). There was no significant difference in the wave latencies, interwave intervals, and amplitudes of cVEMP and oVEMP, among the three groups ( P > 0.05 ). Conclusion. This study found that factors affecting CT, vHIT, HST, and VEMP results included age, head posture and position during testing, stimulus type, manipulation method, and control of muscle tone, and also those that are related to the testing instrument, statistical software, and manipulation procedures, resulting in different excitation rates and testing parameters. The small sample size prevented a comprehensive assessment of the differences in vestibular function between patients with Meniere's disease and acute hypotonic sensorineural hearing loss, and a larger sample size will be investigated in the future to provide useful insight into the diagnosis, treatment and differentiation of Meniere’s disease, and acute hypotonic sensorineural hearing loss.

“…As with the VOR gain, the saccades velocity indicates the vestibular impairment ( Leigh and Zee, 2015 ). Furthermore, saccades on the healthy side of vestibular neuritis and MD may be due to position errors, an intuitive process ( de Brouwer et al., 2002 ; Du et al., 2021 , 2022b ). The combined input of oculomotor and cervical proprioception is another saccadic trigger factor ( MacDougall and Curthoys, 2012 ; Van Nechel et al., 2018 ).…”

“…Reduced vestibular ocular reflex (VOR) gain and overt or covert catch-up saccades are the two pathological signs of vHIT [ 28 ]. Patients with unilateral vestibular loss (UVL) have a reduced VOR gain of less than 0.7 during the head turn to their affected ear [ 29 ].…”

Background Migraine, vestibular migraine (VM) and tension-type headache (TTH) are the most common disorders in dizziness and headache clinics, associated with dizziness or vertigo and postural imbalance, causing a substantial burden on the individual and the society. The objective of this research was to examine the presence of spontaneous nystagmus, comorbidity of benign paroxysmal positional vertigo (BPPV), and Tumarkin fall in patients; additionally, the study focused on assessing the patients’ responses to bithermal caloric irrigation and video head impulse test (vHIT). Methods Consecutive patients diagnosed with migraine, VM, and TTH according to the International Classification of Headache Disorders, third edition (beta version (ICHD-3β)), who were referred to Dizziness and Headache Clinic were enrolled. BPPV and Tumarkin fall were assessed by questionnaires. The presence of BPPV was further evaluated through Dix-Hallpike or head roll maneuver, while spontaneous nystagmus was monitored using video-oculography during interictal period. Lastly, patients’ responses to bithermal caloric irrigation and vHIT were analyzed. Results There was a significantly higher incidence of spontaneous nystagmus in VM compared to both migraine and TTH. The drop attack episodes were slightly more frequent in VM than in TTH and migraine, though not statistically significant. The prevalence of BPPV was significantly higher in VM than in migraine and TTH. Unilateral vestibular paresis was more common in the VM group than in migraine and TTH. There was profound unilateral weakness (UW) in VM patients than in migraine, but no significant difference was found between VM and TTH. In VM, the percentage of saccades along with reduced vHIT gain was significantly higher than in migraine. Lastly, the percentage of abnormal response in vHIT was significantly lower than the percentage of abnormal UW in caloric irrigation across all groups. Conclusions In VM patients, the prevalences of decompensated peripheral damage and BPPV were higher than in migraine and TTH patients as disclosed by the presence of peripheral spontaneous nystagmus and abnormal vHIT during the interictal period. Our findings suggest that the peripheral vestibular system acts as a significant mechanism in the pathogenesis of VM, and it might also be involved in migraine and TTH cases without vertigo symptoms.
