Filter by:This is prospective, randomised double-blind study that will be conducted in the emergency department of 3 university hospitals (FB Monastir, Sahloul Sousse, and FH Sousse) to compare the efficacy of two doses of diazepam (Valium®) and placebo for the relief of acute periphery vertigo in the ED
The main objective is to analyze the abnormality of physical condition, mental health and blood examination of the patients with benign paroxysmal positional vertigo (BPPV). Besides, the investigators aim to establish a database of BPPV based on multimodal magnetic resonance imaging data in the brain to identify high-risk patients with residual dizziness (RD) and systematically establish the comprehensive assessment system for the precise diagnosis, treatment and recovery of RD, optimize the tactics of BPPV management in China.
The purpose of this study is to evaluate the sensitivity and specificity of the video head impulse test (vHIT) device, when implemented in the acute ED setting to identify acute ischemic stroke or central pathology vs peripheral vestibular dysfunction in patient's presenting with vertigo. This study will evaluate the implementation of the device, consistency with current diagnostic standards, unnecessary administration of antithrombolytics and will further study the reduction in hospital admissions and overall healthcare costs.
Randomized double blind placebo controlled trial of vitamin D supplements, with or without calcium supplementation, versus placebo in reduction of recurrences in BPPV.
Balance is the ability to control and maintain the body's center of gravity within the support area. One of the important causes of imbalance is right or left sided unilateral vestibular hypofunction. Chronic vestibular hypofunction describes the loss of unilateral peripheral vestibular function lasting more than 3 months. VES is an important method for replacing the sensory afferents lost in the sudden onset of unilateral vestibular hypofunction and for the correct processing of information in the balance center. Regarding the mechanism of action of Vestibular Electrical Stimulation (VES), it is suggested that it generally affects the auditory system at various levels. Study aimed which was planned as a prospective, randomized, single-blind and single-center study, was conducted between 1 September 2022 and 1 July 2023, to Istanbul University, Istanbul Faculty of Medicine, Department of Physical Medicine and Rehabilitation, Vertigo Rehabilitation Outpatient Clinic with chronic vestibular hypofunction and the inclusion criteria. It was planned to include at least 100 matching patients. Participants who meet the inclusion criteria will be randomized into two groups by computer program after they are numbered according to the order of application. VES and exercise therapy will be applied by wearing pinhole glasses to 50 participants selected to Group 1 (G1-Experimental group). VES and exercise therapy without wearing pinhole glasses in 50 participants selected in Group 2 (G2-Control group) will be applied. Before and after the treatment, the severity of dizziness due to vestibular hypofunction, their emotional state, functionality and physical state and balance status will be evaluated. Dizziness severity will be evaluated with a visual analog scale, and emotional status, functionality and physical condition will be evaluated with the Dizziness Disability Inventory (DHI). Balance status will be determined by Tandem Gait Test, Timed Up and Go Test and Berg Balance Test. Evaluations will be made before treatment, at 1 month of treatment, and at 3 months of treatment (1 month after the end of treatment) by another study blind to treatment. With the data provided as a result of the research, it has contributed to both our country and the world literature, besides vestibular electrical stimulation, which can be used in the treatment of vestibular hypofunction, we will draw attention to the effectiveness of the use of pinhole glasses.
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 aim of this study was to investigate the effect of proprioceptive vestibular rehabilitation on balance, functional mobility, posture, sensory profile and quality of life in patients with vertigo due to peripheral vestibular hypofunction.
Background and Rationale: Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo, affecting 2.4% of the general population and 30% of those over 70 years old. The main symptom is the perceived sensation of movement of the surrounding or self, without actual such movement, triggered by changes in position (positional vertigo). It can be dangerous as repetitive symptoms can lead to falls and depression, particularly in the elderly. Additionally, at least half of those with initial symptoms of BPPV will have ongoing symptoms if not treated. The Epley maneuver is a particle-repositioning maneuver that is used to treat posterior semicircular canal BPPV, the most common type of BPPV, after a diagnosis has been made on physical examination. In-office administration of the Epley maneuver by a specialist yields a 90% success rate at treating the condition; however, at-home administration is much less successful. In a previous paper we demonstrated the development and face validation of a Virtual Reality Epley Maneuver System (VREMS) for performing the Epley maneuver correctly. In this study we aim to apply VREMS treatment in patients who have been diagnosed with BPPV. Research Question and Objectives: PICO (Patient/Population Intervention Compare Outcome): In adult patients diagnosed with posterior canal BPPV by a specialist, does VREMS, as compared to self-performed Epley maneuver using an instructional handout (IH) result in improved or resolved symptoms? Methods: Vertigo patients referred to the Neurovestibular Clinic will be evaluated by an Ear, Nose and Throat (ENT) specialist. Those who are diagnosed with posterior canal BPPV after history and physical examination including the Dix-Hallpike test will be approached to be recruited into the study. Patients who consent to participating in the study will be allocated to either the VREMS cohort or the control cohort. Those in the control cohort will be provided an instructional handout (IH) to help them perform the Epley maneuver. Patients in the VREMS cohort will be provided with the VREMS device, which will help guide them through the Epley maneuver in a virtual reality environment. All participants will be asked to rate the severity of their symptoms before undergoing the Epley maneuver. Subsequently, patients will be supervised as they perform the Epley maneuver - VREMS assisted or based on reading the IH. In both groups, once the patient has performed the Epley maneuver (whether with VREMS assistance or with the IH), they will be asked to rate their symptom severity after undergoing the Epley maneuver. All patients will also be asked to complete the NASA Task Load Index (NASA-TLX) to gauge their perceived mental workload. They will also be given an opportunity to give free-text feedback. For any patient with residual BPPV symptoms following Epley maneuver with VREMS or IH, the ENT specialist/vestibular physiotherapist will perform the Epley maneuver to ensure resolution of symptoms if possible prior to discharge from the clinic. The primary outcome of the study will be the improvement in and resolution of BPPV symptoms with VREMS use as compared to IH. Secondary outcome will be mental workload in each of the study arms.
The specific aims of this pilot project are: Aim #1: Determine the extent to which sensory integration strategies differ between 28 individuals with unilateral vestibular hypofunction and 28 age-matched peers. Participants' postural sway will be recorded as they experience two levels of moving stars10 and white noise, while standing on the floor or a compliant surface. Our working hypothesis is that patients with vestibular hypofunction utilize substitution strategies such that they will demonstrate greater visual and auditory reliance compared with controls, particularly when somatosensory cues are reduced via the support surface. We will then explore whether these mechanism changes after training. Aim #2: Develop the protocol and establish the feasibility of a randomized controlled trial (RCT) comparing C.S.I. training to standard vestibular rehabilitation. Following the assessment, the 28 patients will be randomized into standard vestibular rehabilitation vs. C.S.I. training. This pilot study will enable us to test the feasibility of our recruitment, randomization procedures, establish attrition rate, and test the training protocol. Aim #3: Generate pilot data for sample size calculation for a properly powered RCT. The follow up RCT will test the effect of C.S.I. training on: Visual Vertigo Analog Scale (VVAS), Functional Gait Analysis (primary); balance confidence, overall disability (descriptive). In our preliminary study, 8 patients met the inclusion criteria for the current proposal. Following the C.S.I. training, they had a large effect size of 1.17 on the VVAS. The current study will allow us to identify the between-group effect size for the VVAS and for a functional gait outcome.
Vertigo is a common complaint in the Emergency Department (ED). The differential diagnosis of central and peripheral vertigo is a difficult issue that directly affects mortality. Magnetic resonance imaging (MRI) is the preferred diagnostic tool, but may not be suitable in all patients due to logistic and economic conditions. In this study, the investigators evaluated the role of thiol/disulfide homeostasis (TDH) parameters and ischemia modified albumin (IMA) levels to assist in the value of being used instead of MRI.
