This study analyzes 65 cases based on diagnostic criteria for acute unilateral vestibulopathy/vestibular neuritis (AUVP/VN) 2022.MethodThrough medical history, physical examinations, and vestibular function tests, including the caloric test, video-head impulse test (v-HIT), and vestibular evoked myogenic potentials (VEMPs), we thoroughly tested vestibular receptor dysfunction of AUVP/VN cases. Patients were divided into two groups: total vestibular nerve branch dysfunction (tVND) and partial vestibular nerve branch dysfunction (pVND). The tVND group was defined as involving all receptors innervated by the superior and/or inferior vestibular nerve. The pVND group was defined as involving any other combination pattern of vestibular receptors (at least one). Sociodemographic and clinical characteristics were analyzed. All patients were followed up for 6 months. Changes in DHI scale scores and residual or new symptoms were investigated.ResultsA total of 65 AUVP/VN patients with vestibular receptor dysfunction were included. There were 51 cases in the pVND group and 14 in the tVND group. Compared to the pVND group, the tVND group showed longer vertigo duration (p < 0.05), higher rates of postural symptoms (p < 0.01), higher rates of abnormal caloric tests (p < 0.05), higher canal paresis values (p < 0.001), and higher rates of deficient vestibulo-ocular reflex (VOR) gain in v-HIT (p < 0.001). After a 6-month follow-up, the pVND group showed lower DHI scores (p < 0.001) and higher cure rate (p < 0.001).ConclusionsIn general, patients in the tVND group showed a more severe disease and worse prognosis than those in the pVND group. The substitution of the term AUVP for VN is appropriate and aligns with the clinical characteristics of the cases. However, the diagnosis of AUVP should be further developed to include otolith organ dysfunction.","PeriodicalId":49960,"journal":{"name":"Journal of Vestibular Research-Equilibrium & Orientation","volume":" ","pages":"73-81"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143460256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the examination, we meticulously recorded and compared the VOR gain values in the six canal planes-right lateral (RL), left lateral (LL), right anterior-left posterior (RALP), and left anterior-right posterior (LARP)-with the camera positioned on the left side first, followed by repositioning on the right side. We evaluated instantaneous gain (40 ms, 60 ms, and 80 ms), 0-100 ms median gain, and regression gain in 0-100 ms for all SCs.Results: For horizontal canals, higher VOR gain values were recorded when the camera was positioned on the same side as the canal being tested. The gain value in LARP was higher when the camera was on the left side than on the right side, while the gain value in RALP was higher when the camera was on the right side than on the left side.Conclusion: This study underscores the importance of camera positioning on VOR gain values for both lateral and vertical canals during vHIT. To mitigate the effects of these variables, standardization of operational procedures and equipment settings is crucial.","PeriodicalId":49960,"journal":{"name":"Journal of Vestibular Research-Equilibrium & Orientation","volume":" ","pages":"9574271251323266"},"PeriodicalIF":2.9,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143494492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Few studies have evaluated physical activity levels in individuals with chronic dizziness, and none have specifically focused on the two most prevalent types: vestibular migraine (VM) and persistent postural perceptual dizziness (PPPD).Objective: Evaluate self-reported physical activity levels in individuals diagnosed with PPPD and VM who are awaiting vestibular rehabilitation.Methods: In a retrospective cross-sectional study, we extracted data from the electronic healthcare records involving 121 individuals presenting either VM or PPPD, referred for vestibular rehabilitation at National Hospital for Neurology and Neurosurgery, University College London. Data on IPAQ (International Physical Activity Questionnaire) and DHI (dizziness handicap inventory) questionnaires were analysed across groups.Results: The total sample consisted of 94 (77.7%) women and 27 (22.3%) men with a median age of 56 years old, ranging from 17 to 81 years (P25 = 41 and P75 = 64). Regarding the total sample, a minority (9.1%) of the individuals scored a high activity level on the IPAQ. We observed a significant difference between VM and PPPD in IPAQ score distribution (p = 0.039, Mann-Whitney). Within the category of high physical activity, a larger proportion of individuals had VM compared to PPPD. An inverse correlation was found between DHI and IPAQ (the lower IPAQ, the higher DHI) in the PPPD group (p<0.003).Conclusions: In a sample of individuals with PPPD and VM referred for vestibular rehabilitation, only a minority demonstrated high physical activity levels on the IPAQ, with PPPD exhibiting lower activity levels compared to those with VM.","PeriodicalId":49960,"journal":{"name":"Journal of Vestibular Research-Equilibrium & Orientation","volume":" ","pages":"9574271251318971"},"PeriodicalIF":2.9,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143460301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vestibulo-ocular reflex gain and incidence of corrective saccades of anterior, horizontal, and posterior SCC (ASCC, HSCC, and PSCC) were examined using vHIT. Pathological vHIT results referred to decreased VOR gain and presence of corrective saccades.Results: (1) The pathological rate of each SCC in RHSD group was the highest. (2) Impairment pattern of SCCs can be divided into 7 types based on vHIT results. The pattern of ASCC + HSCC + PSCC disability was the most common in RHSD patients (12/23, 52.2%). In the VN group, the HSCC deficit alone was the most common (16/44, 36.4%), followed by HSCC + ASCC impairment (13/44, 29.5%). In SHLV patients, the most common type was the PSCC deficit alone (26/70, 37.1%). (3) The system cluster analysis revealed that the injury of all SCCs in RHSD patients, the deficit of HSCC alone in VN patients, and the impairment of PSCC alone in SHLV patients showed the farthest distance from other injury patterns.Conclusion: SCCs deficit showed more severe and extensive vestibular impairment in RHSD compared with VN and SHLV, suggesting these three peripheral acute vestibular disorders may have different pathophysiologic mechanisms.","PeriodicalId":49960,"journal":{"name":"Journal of Vestibular Research-Equilibrium & Orientation","volume":" ","pages":"9574271251313801"},"PeriodicalIF":2.9,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143460285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The walking speed effect was assessed by mixed-effects models, and results were visually compared to previous results.Results: Walking speed affected the means of step length, step time and double support time (p < .0001) but not step width (p = .373) and significantly affected the CoV of all parameters (p < .01). These values, as well as speed-related changes, were comparable between contexts.Conclusions: Concurrent DVA and gait assessment seems promising as an assessment method in people with BVP.
