This cohort included 50 males (mean age 41.11 ± 15.98) and 55 females (mean age 35.52 ± 15.07), with no statistically significant age difference between the genders (<i>P</i> = 0.078). Participants were categorized into six age brackets: 11-20, 21-30, 31-40, 41-50, 51-60, and 61-70. For each test, the recording device was consistently positioned on the left side of the goggles, and the tests were conducted by a right-handed operator.ResultsThe average regression gain for left anterior-right posterior canals (LARP) was 1.44 ± 0.19, significantly surpassing that of right anterior-left posterior canals (RALP) at 1.09 ± 0.13 (<i>p</i> < 0.001) and horizontal semicircular canals (HSC) at 1.11 ± 0.07 (<i>p</i> < 0.001). No significant difference was observed between the VOR gains of RALP and HSC (<i>p</i> = 0.1077). Additionally, VOR gain values did not show significant variation across different age groups. In a gender-based analysis, a marginally higher HSC gain was observed in females (1.13 ± 0.07) compared to males (1.11 ± 0.07; <i>p</i> = 0.042), while no significant gender disparity was noted for RALP gains (females: 1.09 ± 0.11; males: 1.10 ± 0.14; <i>p</i> = 0.641).

JF calculates unilateral weakness (UW) by subtracting the weaker ear (WE) response from the stronger ear (SE) and using the sum of both responses as a reference. However, the result is unwieldy and may mislead clinicians if interpreted as an indication of how much weaker the response of the WE is compared to the contralateral SE as a percentage. Through mathematical analysis, we examined what question JF answers and explored, for each vestibular test, alternative asymmetry equations for a more meaningful assessment of vestibular asymmetry. JF has three key limitations. First, its nonlinear nature leads to an underestimation of paresis, particularly when the WE response is near 41% of SE, where the calculated UW is capped at 18%. Second, JF derives the asymmetry from a \"symmetry point\", splitting the difference between both sides, with the average response in the middle, rather than directly quantifying UW as clinicians understand it. Instead, JF answers two separate questions: \"How much is the WE response below the average\" and \"How much is the SE response above the average.\" To address these issues, a linear paresis calculation using only the SE response as a reference was later introduced. However, this approach did not resolve JF's third limitation: artificially inflated values and sensitivity to small variations in WE when both ears are affected. Unlike the caloric test, the vHIT already relies on head velocity as an absolute reference for gain calculation, eliminating the need for SE in asymmetry calculation. Employing an ideal gain of 1, asymmetry can be expressed as a simple side-to-side gain difference, preventing inflated results in bilateral deficits and easing clinical calculation.</p>","PeriodicalId":49960,"journal":{"name":"Journal of Vestibular Research-Equilibrium & Orientation","volume":" ","pages":"3-14"},"PeriodicalIF":3.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12664924/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144030255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies involving numerical simulations of hydrops in the vestibule, cochlea, or both were included.ResultsEight studies on hydrodynamics in hydrops using numerical simulations were included. In cochlear models, hydrops affect basilar membrane mechanics, causing low-frequency hearing loss, auditory distortions, and frequency shifts. Vestibular models revealed increased static pressure in the horizontal semicircular canal, explaining abnormal vHIT findings in hydrops patients. Models also suggested chaotic fluid dynamics in dilated labyrinthine structures during caloric tests.
