Filter by:Resection of the vestibular schwannoma leads to acute peripheral or combined vestibular loss caused by a surgical lesion to the branches of the vestibular nerve and, less frequently also the lesion of the cerebellum. The lesion presents in patients with postural instability, vertigo, oscillopsia, and vegetative symptoms that may accompany it. The organism reacts to this state with the process of central compensation with the significant role of the cerebellum. The goal of the rehabilitation is to support this process and thus to make recovery faster and more efficient since not all patients are capable of complete restoration of the vestibular function. Up to date, rehabilitation includes, apart from the specific vestibular exercise, also the possibility of modern techniques using virtual reality space and prehabituation. Thanks to prehabituation, i.e., chemical labyrinthectomy with intratympanically installed gentamicin, the timing of the origin of the acute vestibular loss and the surgical procedure is separated. Therefore, there is a chance of achieving vestibular compensation before vestibular schwannoma removal. In the last decade, due to the advances in technology in the field of computer games and the applications for smartphones, the tools for virtual reality have become less expensive and more available in common praxis. Virtual reality is a technique for generating an environment that can strengthen three-dimensional optokinetic stimulation, subsequently the process of central compensation. Overall, it may shorten the time of recovery after the surgery and improve patients' quality of life.
This parallel-group randomized controlled trial aims to determine if the location of the lesion(s) in the vestibular system (unilateral versus bilateral, lateral semi-circular canal versus otolith) impacts the effectiveness of adjunct take-home head-mounted display (HMD) virtual reality (VR) therapy in improving patient symptomatology. Fifty patients meeting inclusion criteria will be recruited from the principal investigator's neurotology clinic. Baseline symptomatology questionnaires will be completed, followed by random allocation to virtual reality and control groups. Vestibular rehabilitation and virtual reality protocols will be adhered to for 4 to 8 weeks, followed by symptomatology questionnaires. Data analysis will be conducted to answer the study's objectives.
Comparing severity of diabetic peripheral neuropathy (small and large fibers including autonomic neuroapthy) to postural control and vestibular measurements
Vestibular disorders are among the most common causes of disability in society and affect over 50% of the population over the age of 65 and a significant percentage of the younger population. Vestibular disorders have a dramatic impact on daily life impacting work, relationships, and even activities of daily living.The OtoBand has shown promise and might be beneficial for treating or improving the course of recovery from vestibular disorders. This study seeks to quantify the effect of the study device, the OtoBand, on objective measures of dizziness and vertigo in patients with vestibular dysfunction. The study will be conducted at a single-site and will be a blinded, randomized, placebo-controlled design in which participants do not know if they are receiving bone conducted stimulation 1) at a therapeutic level or 2) at a non therapeutic level.
The vestibular system is a part of the inner ear and functions as a motion sensor. It provides the central nervous system with information about changes of the head position. This information is essential for the proper functioning of the balance system. In particular, it ensures effective postural control and gaze stabilization. Abrupt vestibular deficit is defined as a sudden loss of the vestibular function. In the acute phase the patient presents mainly with intense rotatory vertigo and instability, most often accompanied by nausea. The symptoms are exacerbated by head movements. The diagnosis is made by observation of a spontaneous nystagmus, measurement of a pathological head impulse test and an asymmetric response to caloric tests, in the absence of other neurological symptoms. Although the etiology is unknown, it could be of viral or vascular origin. Symptoms usually regress within a few days or weeks. Vestibular function recovers in about half of the cases, in the other half a central compensation process is set up. The benefit of a 3-week course of corticosteroids has been demonstrated in one study. The dosage has been debated. The aim of this study is to demonstrate the benefit of a 10-day course of oral corticosteroids. The primary objective is to demonstrate a significant reduction in the rate of asymmetry of caloric response and the secondary objective is to demonstrate a significant reduction in the impact of symptoms assessed with the Dizziness Handicap Inventory (DHI) score at 1 year.
The purpose of investigation is to assess the levels of metabolic factors (hydroxyvitamin D, homocysteine) between patients with vestibular dysfunction of peripheral origin (BPPV) and central origin (vestibular migraine). Also we will analyse another factors (such as anxiety and depression) and optimize therapeuthical approach accordingly with the data.
Vestibular neuritis is the second cause of vertigo, it constitutes 5 to 6% of the aetiologies of vertigo in an otoneurological consultation. Infection or reactivation of a neurotropic virus of the herpes group (HSV-1) in the vestibular lymph node is thought to be the cause of the unilateral vestibular deficit. Upper vestibular neuritis is more common than lower, or total involvement. Goebel (2) explains this by an anatomical predisposition of the vestibular nerve canal to inflammation, unlike the singular nerve canal which is shorter and wider giving way to a certain degree of edema without consequence on its contents. However, the innervation territory of the superior vestibular nerve is superimposable on the territory supplied by the anterior vestibular artery. The anterior, lateral semicircular canals and the utricle are affected. Current complementary vestibular and imaging examinations cannot differentiate between inflammatory or vascular involvement in upper vestibular neuritis. The increased presence of cardiovascular risk factors in patients with upper vestibular neuritis would be an argument in favor of ischemic involvement of the anterior vestibular artery.
Gaze stability exercise is a medical procedure for persons with unilateral vestibular disturbances such as vestibular neuritis or persons who have had tumors of their 8th nerve. They are a crucial part of the vestibular dysfunction rehabilitation protocols in health centers. These activities which involve turning one's eyes at different angles while having their eyes focused on an optotype are aimed at helping improve the vestibular ocular reflex (VOR), visual acuity during head movements and also reducing vertigo and dizziness. Study aim: This review will be establishing the effectiveness of applying gaze stability with balance exercises procedure among participants who are suffering vertigo due to vestibular neuritis. Methods: Twenty volunteers between the age of 25-59 years old, diagnosed, and confirmed to be suffering from vestibular neuritis and vertigo will be used in this study. Gaze stability exercises will be performed while patients are in a seated position. Each exercise will last for 30 seconds and be done in phases that included; eyeball movement, saccadic eye movement, pursuit eye movement, vergence eye movement, and vestibular-ocular reflex exercise. Balance exercises will be performed in a standing position including both static and dynamic training with or without closing eyes. The following outcome measures for each participant will be assessed pre-and post-treatment after completing four weeks of intervention. They include; Arabic version of Activities-Specific Balance Confidence Scale (A-ABC scale), Arabic version of Dizziness Handicap Inventory (A-DHI), Berg Balance Scale (BBS), and Katz Index of Independence in Activities of Daily Living (Katz ADL). The findings will then be subjected to statistical methods and data analysis using the SPSS toolkit. In this study we hypothesis that practicing gaze stability and balance exercises will have a positive influence on balance and activities of daily living among vestibular neuritis patients.
The purpose of the study is to create a vHIT- and VOG-model for bilateral vestibular neuronitis, via ethanol administration in healthy human subjects.
Vestibular neuritis is a brutal and continuous dizzying syndrome of peripheral (vestibular) origin without cochlear or other associated involvement. Specifically, vestibular neuritis is inflammation of the nerve that innervates the vestibular canals (the inner ear). It is characterized by the sudden onset of intense and prolonged vertigo accompanied by postural imbalance, nausea and vomiting, without hearing impairment or other neurological symptoms. Vestibular neuritis is the second cause of peripheral vertigo after benign paroxysmal positional vertigo. It represents approximately 7% of patients consulting for vertigo. The purpose of this study is to evaluate if wearing Boarding Ring glasses can be accelerated vestibular compensation.
