Objective: This study aimed to develop and evaluate a novel software tool for robust analysis of the Visually Enhanced Vestibular-Ocular Reflex (VVOR) and video head impulse test (vHIT) saccades.
Methods: A retrospective study was conducted on 94 patients with Meniere's Disease (MD), unilateral vestibular hypofunction (UVH), and vestibular migraine (VM). The MATLAB-based VVOR Analysis System and Saccades All in One software were utilized for data processing. New techniques, VVOR_diff and VVOR_cycle, were deployed for saccade parameter extraction.
Results: Saccade incidence rates, examined through vHIT, VVOR_diff, and VVOR_cycle, exhibited distinct patterns in MD, UVH, and VM patients. Frequent instances of multiple saccades within a single cycle were noted on the affected side in MD and UVH patients. Statistically significant differences in saccade gain and incidence rates between the affected and unaffected sides were evident in MD and UVH patients. Notably, high inter-method and intra-method correlations suggested consistency across different methods and potential interactions within one.
Conclusion: The software proved effective in extracting saccades and reducing noise in VVOR data, thereby enhancing the evaluation of vestibular function and potentially improving diagnostic accuracy for vestibular disorders.

Aim: To explore the full spectrum of symptoms and impacts associated with chronic unilateral vestibular hypofunction (UVH), and to assess whether these symptoms and impacts are fully covered by patient-reported outcome measures (PROMs) within the International Classification of Functioning, Disability and Health (ICF) framework.
Methods: A qualitative study was conducted using semi-structured interviews, which were recorded, transcribed, and analyzed by two independent reviewers through a consensus approach. Data collection continued until thematic saturation was reached.

: Vagus nerve stimulation (VNS) is a frequently used neuromodulation method in recent years. While the mechanism of improvement in diseases such as epilepsy, dementia, and depression is being studied, its potential effect on vestibular dysfunction is also being investigated. The aim of our study was to investigate the effect of transcutaneous auricular VNS (taVNS) on the vestibular symptoms of unilateral vestibular hypofunction (UVH).

Objective: This study aimed to compare the efficacy of medication combined with personalized vestibular rehabilitation training (VRT) versus medication alone in unilateral vestibular hypofunction (UVH) and identify predictors of long-term symptom progression.
Methods: Forty-eight UVH patients were randomized into a VRT group (n = 23, medication combined with personalized VRT) and a control group (n = 25, medication alone). Bithermal caloric tests, Dizziness Handicap Inventory (DHI), Vestibular Rehabilitation Benefit Questionnaire (VRBQ), Visual Analog Scale (VAS), Activities-specific Balance Confidence Scale (ABC), and Self-Rating Anxiety Scale (SAS) were assessed at baseline, 2 weeks, and 4 weeks.

PurposeBalance and vestibular disorders have a profound impact on quality of life. Anxiety (ANX) and depression (DEP) are common with dizziness, vertigo, or imbalance. It is unclear whether self-reported anxiety or depression depends on perceived physical function for individuals participating in vestibular rehabilitation (VPT).

Aims: Ventricular relaxation creates an intraventricular pressure difference (IVPD) and resultant diastolic suction. Non-invasive estimation by echocardiographic techniques would allow to clinically evaluate IVPD as an important component of diastolic functional assessment. The aims of the current study were to evaluate the accuracy of IVPD estimation based on Blood Speckle Tracking (BST) echocardiography compared with invasive pressure measurements and to clinically apply the method in children with univentricular hearts (UVH) and controls.
