Active clinical trials for "Vestibular Diseases"

Disorders of vestibular function and balance are an important component of many conditions that commonly affect veterans, such as inner ear diseases, diabetes, and traumatic brain injury. Veterans with vestibular impairment have reduced quality of life, limitations on work and physical activities, and an increased risk of falls. The goal of this research is to develop a more engaging and effective interactive tool for vestibular rehabilitation to improve the lives of affected veterans. The first steps in this process will be to test the ability of the application to facilitate vestibular learning and to test its feasibility in vestibular patients. The hypothesis is that computer-game-based adaptation will induce robust VOR motor learning and will provide an engaging platform for vestibular rehabilitation. Ultimately, our application has the potential to provide more flexible vestibular exercises that will allow therapy to be customized for each patient. It will also have the ability to track a patient's progress over time and to advance exercises as function improves.

Patients with chronic bilateral vestibular hypofunction may suffer from a visual instability during head movement called oscillopsia. Visual consequence of vestibular deficit can lead to a severe impairment of their quality of life. However, correcting saccades during rapid head movement, called covert-saccades, have been more recently identified. These saccades, which occur during the head movement in patients with vestibular hypofunction, present a very short latency. They could compensate for the lack of vestibular-ocular reflex and greatly decrease oscillopsia and visual impairment. The objective of this study is to evaluate the potential functional benefice of these compensatory movements in a population of 20 patients with chronic bilateral areflexia, in a cross-sectional study.

The purpose of this study is to study the relationship between the vestibular system and chronobiology

This study will utilise an assessor blinded, randomised controlled design to investigate the acceptability and feasibility of providing a novel tele-rehabilitation balance training system (HOLOBalance) for community dwelling older adults at risk for falls. Older adults (age 65-80) who meet the inclusion criteria (e.g. independently living, no neurological conditions) will be recruited from falls services and from the wider community (via AgeUK) and will be randomly allocated to receive either a prescribed exercise programme delivered by: 1) the HOLOBalance tele-rehabilitation system or 2) an exercise booklet (The OTAGO Home Exercise Programme). Participants will be required to perform a series of prescribed exercises each day (duration of up to 30 minutes per day) for the entirety of the 8-week exercise programme. These exercises will be provided via the HOLOBalance tele-rehabilitation system (intervention arm) or by written instructions (control arm). Primary objectives for this study are to assess recruitment rate, compliance with exercise programmes (exercise diaries) and drop-out rates within the intervention group and a control group undertaking standard practice, home based balance rehabilitation (the OTAGO Home Exercise Programme) to explore whether HOLOBalance is acceptable to participants. Furthermore, acceptability to older adults will also be investigated via exit interviews performed within the HOLOBalance tele-rehabilitation intervention arm. Feasibility will be assessed by documenting adverse events (and SAE's), adverse device effects (and SADE's), deviations from protocol and feedback from treating clinicians. Implementation issues such as technology break down, service delivery and usability issues will also be documented. Secondary outcomes to explore trends for effectiveness will investigate performance of both groups at baseline and after the 8 week intervention across a range of outcome measures associated with balance function and falls risk, cognitive function, Physical activity and social participation, and subjective report of mobility and balance.

Specific aim: To determine whether optokinetic stimulation can improve gait abnormalities. Hypothesis: Optokinetic stimulation stimulates the vestibular system and can improve vestibular induced gait disorders.

This study evaluates the vestibular activity in major depression patients and healthy controls using the rotatory test and electronystagmography.

Dizziness, loss of balance, and unsteadiness of gait are common symptoms reported by Emergency Department (ED) patients. The incidence of acute vestibular syndrome (AVS) is increasing and reaches 2-4% of ED visits. In the ED of the Paris Saint Joseph Hospital Group, its incidence was 5% during the year 2019 and 2% during the year 2020 (COVID-19 pandemic period). Emergency medicine is based on a dichotomous principle for any acute pathology in the initial phase. For AVS, the diagnostic dilemma for emergency physicians is usually to differentiate a benign vestibular cause from a potentially serious cerebral cause such as ischemic stroke of the vertebro-basilar territory. The majority of AVS are related to acute vestibulopathies, yet it is necessary to recognize and distinguish a benign paroxysmal positional vertigo (BPPV) from a vestibular neuritis, a vestibular migraine, or a labyrinthine hydrops, to exclude with certainty a cerebral involvement. However, posterior fossa strokes mimic 5% of BPPV and 25% of vestibular neuritis. Among these strokes, about 20% are therefore revealed by a VAS without associated localizing neurological sign. In the absence of a clear neurological sign, the emergency physician must therefore decide whether to treat the patient as an outpatient when he or she suspects a AVS of "peripheral" origin (otolaryngology), or as an inpatient when he or she suspects a "central" origin, in particular a stroke.

The overall aim of this study is to elucidate the impact of a vestibular dysfunction on the cognitive and motor performance by means of an extensive test protocol, evaluating the vestibular, cognitive and motor function using single as well as dual-task paradigms.

There is currently no score in French for evaluating disorders of the child's balance. Only one questionnaire was validated in the child in English in 2016, the " Pediatric Vestibular Symptom Questionnaire ". The objective of the research is to validate the French translation of this questionnaire.

No studies have explored how patients with chronic dizziness react to a diagnosis of Persistent Postural Perceptual Dizziness (3PD) and their beliefs and representations of the diagnostic label. Investigating the experience of diagnostic labelling from the perspective of patients will allow clinicians to recognise whether this is a helpful term to adopt and ways to improve the clinical consultation. This is a qualitative study that will consist of semi-structured interviews with people with a new diagnosis of 3PD. The main objective of the study is to explore how patients react to this diagnostic label, what they understand about their diagnosis and how their own meanings affect their expectations and illness perceptions. Between 12-15 patients will be recruited from the balance clinic at Guy's Hospital, London, UK. The qualitative data will be analysed using thematic analysis which will draw on pragmatic interpretive descriptive methodology.
