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.
Comparing severity of diabetic peripheral neuropathy (small and large fibers including autonomic neuroapthy) to postural control and vestibular measurements
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.
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.
The objective for this study is to compare outcome measures from vestibular rehabilitation (VPT) delivered in a traditional method against a new device Incremental Velocity Error (IVE) that improves physiologic performance of the vestibulo-ocular reflex. Participants include active duty service members with mild traumatic brain injury (mTBI) and civilians with peripheral vestibular hypofunction. The investigators will use a clinical trial cross-over design with randomization to either the control (VPT) or experimental (IVE) group and measure vestibulo-ocular reflex function as well as subjective and functional outcomes in order to investigate the best means to improve delivery of vestibular rehabilitation.
The pathophysiology of vertigo is complex and usually requires specialist involvement. During the diagnostic process, patients commonly undergo tests which assess the integrity of the gaze and posture stabilisation mechanisms involving the inner ear (vestibular system), the visual systems and the subconscious neural pathways that interconnect them. Whilst these tests are useful they fail to provide information concerning the neural connections to the cortex and therefore neglect the perceptual aspects of disequilibrium. At present the possibility of routine examination of these higher projections remains elusive as no practical alternatives to the expensive functional magnetic resonance imaging systems exist. However, recently a novel method of recording cortical vestibular evoked potentials (CVEPs) has been described. CVEPs utilise an existing method used to interrogate cortical projections from the auditory system in which sound waves stimulate the inner ear and the resulting electrical responses from the brain are recorded. The recent breakthrough is in the realisation that these responses also contain information from the balance organs and therefore are a direct measure of cortical processing of the vestibular inputs. Current evidence shows that CVEPs are present in the normal population and absent in patients with no vestibular function. The primary aim for this study is to extend the patient cohort to include those who have a vestibular injury but retain residual function. Patients going through standard testing will have also have CVEPs on both ears providing seminal information into the effect of injury to the peripheral vestibular system on the cortical pathways. Furthermore, by following the cohort through their complete management pathway it will be possible to ascertain if the CVEP can be used to predict rehabilitation outcome success.
Aim of present study is to determine whether corticosteroids and vestibular exercises are equal effective in the recovery of balance in patients with acute vestibular neuritis.
