Global interest in applying virtual reality (VR) in research and medicine has grown significantly, with potential benefits for patients suffering from balance disorders, instability, and a high risk of falling. This exploratory study assesses the impact of immersive VR (IVR) delivered through a head-mounted display (HMD) on balance and explores the feasibility of using the HMD VR unit as a standalone posturography tool. Using the Meta Quest 2 HMD and a mid-range Android smartphone equipped with standard sensors, the research employed a VR environment that simulated a ship at sea, with thirty-eight healthy participants with no otoneurologic abnormalities.

The main aim of this study is to answer the question whether a simple and short test such as rotation about a vertical axis can be an objective method of assessing balance dysfunction in patients with unilateral vestibular impairments. A 360˚ rotation test was performed using six MediPost devices.

The study included 202 participants divided into two groups, one consisting of 133 patients with canal paresis CP > 19% and one of 69 healthy subjects. Participant was tested according to the standard protocol of static posturography (SP), and with head movements of 0.

This mobility test has never before been investigated as a sole source of data for fall risk assessment. It can be performed in a very limited space and needs only minimal additional equipment, yet provides large amounts of information, as the presented system can obtain much more data than traditional observation by capturing minute details regarding body movement.

(1) Objectives: The evaluation of dizzy patients is difficult due to nonspecific symptoms that require a multi-specialist approach. The Dizziness Handicap Inventory (DHI) is widely used in the assessment of dizziness-related disability, but its clinical efficacy needs further expansion. The aim of this study was to identify the subscales of DHI that may correlate with some vestibular or nonvestibular dysfunctions.

Body movements are detected through the use of force platforms that assess static and dynamic balance (conventional posturography). In recent years, new technologies like wearable sensors (mobile posturography) have been applied during complex dynamic activities to diagnose and rehabilitate balance disorders.

Uncompensated vestibular hypofunction requires vestibular rehabilitation, but access to this form of treatment remains limited. Therefore, innovative methods of rehabilitation utilizing new technologies, which could promote this therapy, are searched for.

Serum samples obtained from 66 patients with LSCC were compared with 100 healthy control subjects. Additionally, miRNA levels were evaluated to identify possible correlations with clinicopathological features.

Introduction: The aim of the study was to investigate the mRNA expression and protein levels of matrix metalloproteinases (MMP) 2 (MMP-2), 9 (MMP-9), 7 (MMP-7) and their tissue inhibitor TIMP-2 in patients with laryngeal squamous cell carcinoma and control subjects and additionally to evaluate a possible correlation with clinicopathological features.
Material And Methods: The expression levels of MMP-2, MMP-9, MMP-7, and TIMP-2 mRNA were detected by the real-time quantitative real time polymerase chain reaction method in 96 cases of laryngeal carcinoma vs. non-tumor tissue.
Background: Recently, two types of movement sensors have been introduced into Virtual Reality (VR) therapy: motion trackers and force-plate platforms. Combining these two methods could produce better rehabilitation outcomes. Such devices, encompassing motion trackers and force platforms, are referred to as "hybrid" VR units.
