Filter by:Although cochlear implants can restore hearing to individuals who have lost cochlear hair cell function, there is no widely available, adequately effective treatment for individuals suffering chronic imbalance, postural instability and unsteady vision due to bilateral vestibular hypofunction. Prior research focused on ototoxic cases has demonstrated that electrical stimulation of the vestibular nerve via a chronically implanted multichannel vestibular implant can partially restore vestibular reflexes that normally maintain steady posture and vision; improve performance on objective measures of postural stability and gait; and improve patient-reported disability and health-related quality of life. This single-arm open-label study extends that research to evaluate outcomes for up to 8 individuals with non-ototoxic bilateral vestibular hypofunction, yielding a total of fifteen adults (age 22-90 years at time of enrollment) divided as equally as possible between ototoxic and non-ototoxic cases.
The study evaluates the implementation of evidence-based practice for the management of patients with dizziness in the emergency department (ED) within a large integrated health care system. The clinical focus is on benign paroxysmal positional vertigo (BPPV), unilateral vestibulopathy (e.g., vestibular neuritis), and stroke - which are disorders with established evidence-base practices for evaluation and management. Evidence-based practices for these clinical topics have not properly disseminated regarding dizziness visits, and this results in missed opportunities for effective and efficient care delivery. The investigators propose a hybrid type 3 effectiveness-implementation trial to evaluate an enhanced BPPV-centric implementation strategy and clinical intervention. The overall strategy, initially developed in Dizziness Treatment through Implementation & Clinical strategy Tactics-1 (DIZZTINCT-1), will be improved to increase generalizability, convenience, exposures, sustainability, and dissemination. We use an innovative design of a stepped-wedge trial for the ED-level implementation strategy and an embedded randomized patient-level dissemination strategy. As a result, we can closely assess the individual and additive impact of study components. We will evaluate effectiveness of the implementation strategy and also confirm clinical outcomes.
The investigators have developed a self-administered rehabilitation tool that incrementally guides the user to increase head motion to mitigate motion sickness and enhance postural recovery following centrifugation or unilateral vestibular nerve deafferentation surgery.
The aim of this study is to test whether when using the Vestibular Rehabilitation App older patients perform rehabilitation in a similar manner as when directly instructed by a clinician. A secondary goal is to evaluate usability and enjoyment of the app.
Vestibular loss can co-occur with hearing loss causing dual sensory deficits. This project examines vestibular loss as a contributing factor to reading difficulties for children with hearing loss, where previously only the effects of hearing loss and subsequent language difficulties have been considered. These results are expected to influence the identification and habilitation of vestibular loss in children with hearing loss.
Intractable symptoms of Meniere's disease will be treated with intratympanic steroids. At the same time intratympanic dexamethasone will be used to rescue hearing
This study has three main goals (1) to explore the effects of electrical stimulations of the peripheral vestibular system(2) to assess the potential of this technique to rehabilitate basic vestibular functions in patients with severe bilateral vestibulopathy, and (3) to take advantage of the unprecedented experimental paradigm provided by the vestibular implant to increase our fundamental knowledge on the contribution of peripheral vestibular function to posture, gait and higher order sensory functions, mechanisms that remain poorly understood.
Vestibular hypofunction is a heterogeneous clinical entity that arises after a vestibular pathway injury, which if not properly compensated becomes chronic, and very often disabling, presenting with postural instability, blurred vision with cephalic movement, oscillopsia, and subjective sensation of dizziness and imbalance. People diagnosed with vestibular hypofunction, because of their clinical condition, often tend to reduce physical activity and lead to a sedentary life, despite the fact that exercise has been shown to improve postural stability, and it is a determining factor in recovery after vestibular injury. Physical activity improves the quality of life and reduces the risk of falls. Supervised exercise is, therefore, among the potentially beneficial adjuvant programs in this population, although little has been studied in comparison with other pathologies. Furthermore, in vestibular hypofunction, there is insufficient evidence on specific interventions in specific clinical situations, the amount of exercise, and the optimal duration of the programs. Therefore, the aims of the study are 1) to analyze the effects on balance by an 8-week period of a supervised exercise program in people with a diagnosis of bilateral or unilateral vestibular hypofunction and 2) to examine the effect of six-months detraining subsequent to intervention. Secondary objectives are to examine the additional effect of the intervention on health-related quality of life, psychological well-being, cardiorespiratory fitness, body composition, blood pressure, physical activity level, sedentary behavior, and sleep quality.
There are only a few cases of isolated lateral canal deficit described in the literature. This study would focus on this group of patients in order to establish an evolving profile, a recovery behavior that we could compare to that in the literature. In addition, the evolving profile as well as the other clinical criteria identified would allow investigators to make hypotheses as to the pathology responsible for a given evolutionary profile. The population studied is represented by adult patients admitted by the emergency consultation service of otolaryngology of the University Hospitals of Strasbourg for an acute unilateral vestibular deficit whose examination at the VHOT shows a reduced and isolated gain of a lateral semicircular canal.
Incidence: Dizziness or vertigo is a very prevalent complaint in the general population, and a common reason for seeking medical attention. In Denmark, 20-30 % have experienced dizziness/vertigo to a degree that has led to disability, sick leave, or medical contact(1). In the United States, dizziness is estimated to account for partly 2.6-4.4 million visits to emergency departments (EDs) each year, partly 4 % of main symptoms in patients admitted to EDs (2). In Germany, the estimated prevalence of dizziness is 20-30 % with an annual incidence about 11 % (3). Terminology and definition: Dizziness or vertigo is not a disease itself but rather a symptom of various underlying disorders. Thus, vestibular, neurological, cardiovascular, metabolic, and psychiatric diseases may be associated with dizziness/vertigo as well as medical side effects. Patients (and professionals) often use the two terms dizziness and vertigo synonymously, which may cause some confusion in the choice of diagnostics. Vertigo is characteristic for vestibular disorders and is defined as sensation of self-motion when no self-motion occurs, or sensation of distorted self-motion during an otherwise normal head movement, whereas dizziness is a feeling of more general unsteadiness. 1. Is implementation of HINTS and v-HIT in an ED able to reduce the number of undiagnosed and misdiagnosed cases of acute onset vertigo as well as diagnostic delay ? 2. What are the effects of immediate and systematic balance training in case of acute vestibular diseases ? 3. What is the cost-effectiveness of implementation of HINTS and v-HIT as up front diagnostics, and systematic balance training in patients with acute vestibular diseases ?
