Effect of Peripheral Vestibular Disease Location on Outcomes Following Home-based Virtual Reality...
Peripheral Vestibular DisorderBenign Paroxysmal Positional Vertigo5 moreThis 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.
Human Visual and Vestibular Motion Perception Study
Vestibular DiseaseThe purpose this study is to measure sensitivity to visual and vestibular or balance motion. It is hoped that the results may help researchers better understand how aging and disease affect motion perception.
The Effect of Computerized Vestibular Function Assessment and Training System Combined With Cognitive/Motor...
Vestibular Function DisorderCognitive Decline2 moreThis study aims to investigate the effect of computerized vestibular function assessment and interactive training system, combined with cognitive/motor dual-task for the elderly with dizziness. The investigators will compare the movement abilities among older adults with different cognitive level, and further establish an assessment module that can evaluate participants' dual-task performance in both vestibular and cognitive tasks. Finally, leveraging the advantages of sensor detection technology and computerized feedback, an appropriate dual-task rehabilitation approach for vestibular function and cognition will be developed.
Genotype-phenotype Correlation Study of Presymptomatic and Symptomatic DFNA9 Patients
Vestibular DiseasesDFNA9DFNA9 (Deafness Autosomal Dominant 9) is an autosomal dominant hereditary hearing loss which is associated with vestibular deterioration. The most recent genotype-phenotype correlation studies have been conducted more than 15 years ago. Meanwhile, emerging and valuable vestibular tests have been added to the vestibular test battery. These tests were not available at the time of the correlation studies. The aim of this study is to carry out a prospective cross-sectional study on symptomatic and presymptomatic affected carriers of the Pro51Ser (P51S) Coagulation Factor C Homology (COCH) mutation in order to correlate vestibular data using the complete vestibular test battery with the known data on hearing and vestibular function in relation to age.
New Rehabilitation Protocol for Patients With PPPD
RehabilitationBalance2 moreThe investigators will test a new rehabilitation protocol on patients with persistent postural perceptual dizziness (PPPD). The investigators hypothesize that patients with PPPD, in the absence of vestibular deficits, do not benefit from standard vestibular rehabilitation but instead need a rehabilitation that acts on visual and postural stability, through training of saccadic movements in dynamic contexts of cognitive-motor dual-task and rehabilitation of postural stability.
Association Between Severe-to-profound Hearing Loss and the Balance Function of the Inner Ear
Hearing LossSensorineural5 moreSevere-to-profound hearing loss can have a major impact on patients´ lives leading to social isolation and decreased quality of life. Most commonly the hearing loss is caused by damage to the inner ear or cochlear nerve. Since the vestibular system which is central for our balance is located in the inner ear it can be suspected that patients with severe-to-profound hearing loss also might have an impaired vestibular function. This impairment may lead to a feeling of dizziness or vertigo. This study aims to investigate if patients with severe-to-profound hearing loss also have impaired vestibular function. The vestibular function will be measured with caloric irrigation, video head impulse test and vestibular evoked myogenic potential.
Menier's Disease - Bone Density Study
Meniere DiseaseOsteoporosis3 moreMeniere's disease is a progressive and debilitating inner ear disease characterised by vertigo and hearing loss. Several studies have linked Menierws disease with lower bone density and lower vitamin D levels. In the current prospective study definite Meniere's patients will be followed over a period of 2 year, during which repetitive measurements of bone density, vitamin D plasma levels, blood pressure as well as hearing and vestibular tests will be made. Results will be compared to healthy controls.
Analysis of Vestibular Compensation Following Clinical Intervention for Vestibular Schwannoma
MigraineVestibular Migraine4 moreMultiple sensory cues are typically generated by discrete events, and while they do not reach the cerebrum simultaneously, the brain can bind them temporally if they are interpreted as corresponding to a single event. The temporal binding of vestibular and non-vestibular sensory cues is poorly understood and has not been studied in detail, despite the fact that the vestibular system operates in an inherently multimodal environment. In this study, the researchers are investigating the physiology and pathophysiology of vestibular temporal binding by studying normal subjects, patients with peripheral and central vestibular dysfunction, and patients with vestibular and cochlear signals provided by prosthetic implants in the inner ear.
Isolated Deficits of the Lateral Semicircular Canal
Peripheral Vestibular DisorderThere 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.
BALANCED GROWTH: The Involvement of the Vestibular System in a Child's Cognitive and Motor Development...
Vestibular DisorderNeurodevelopmental DisordersWhen a vestibular dysfunction occurs at birth or in early stages of life, one might expect that this may have an enormous impact on a child's development. It is known that a severe congenital or early acquired vestibular deficit in children results in delayed psychomotor milestones. Later in life, children with a vestibular dysfunction may have difficulties with several balance tasks and additional cognitive, motor and/or psychosocial performances. While a few authors have suggested that there is indeed an influence of a vestibular dysfunction upon these different developmental domains (cognitive, motor, educational and psychosocial development), which can be supported by findings in clinical practice as well, literature concerning this topic remains fairly limited. On the other hand, several studies have shown that children with known difficulties in motor and/or cognitive functions have more difficulties in vestibular performances in comparison with their unaffected peers. Although more frequently discussed, the literature on this population is rather scarce too. Therefore, the current project aims to investigate the relationship with and the involvement of the vestibular system in the motor and cognitive development of school-aged children.
