Incremental Velocity Error as a New Treatment in Vestibular Rehabilitation

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...


Falls in the elderly population are a major public health problem because of their frequency and their consequences, notably in terms of dependence their cost to society. In most cases, balance disorders related to an impaired vestibular system are blamed, even though there is no formal evidence that this is the case. Vestibular tests in routine otoneurological practice are based on the exploration of vestibulo-ocular or even vestibulo-cortical reflexes. They are not particula...

Hearing Loss, Vestibular Loss and Cognitive Performance

Hearing loss is an established independent risk factor for dementia. Likewise, recent research demonstrated cognitive deficits in subjects with vestibular loss. However, in these studies data have not been adjusted for the hearing status of the enrolled study subjects. As hearing loss prevalence is high in patients with vestibular loss, this could be a major confounder. Therefore, in this study the investigators investigate cognition in patients with bilateral vestibulopathy wi...

Three-dimensional Virtual Reality Procedures in Vestibular Rehabilitation

The aim of the present study will be to discover possible (i) improvements achievable in unilateral vestibular hypofunction patients using a self-assessed head-mounted device (HMD)-based gaming procedure when combined with a classical vestibular rehabilitation protocol (HMD group) as compared with a group undergoing only vestibular rehabilitation and (ii) HMD procedure-related side effects. Main outcomes will be: otoneurological testing (vestibulo-ocular reflex gain study by me...

Multichannel Vestibular Implant Early Feasibility Study

Although cochlear implants can restore hearing to individuals who have lost cochlear hair cell function, there is no adequately effective treatment for individuals suffering chronic imbalance, postural instability and unsteady vision due to loss of vestibular hair cell function. Preclinical studies have demonstrated that electrical stimulation of the vestibular nerve via a chronically implanted multichannel vestibular prosthesis can partially restore vestibular reflexes that ma...

The Effect of Vestibulo-ocular Reflex Improving Exercise on Gait and Balance Among Post Stroke Sub Acute Patients

This study evaluate the effect of Vestibular rehabilitaion program as part of physical therapy during rehabilitation post stroke. half of participants will recieve cestibular exercise as part of the Physiotherpy session, while the other half will recive a conservative physiotherapy session.

Correlation of Radiological Lesions With Vestibular Function in Patients With Bilateral Vestibulopathy

In 2014 radiologic lesions were detected at one or more semicircular canals using CT and MR imaging of temporal bone in subjects carrying the p.P51S mutation in COCH. These lesions are believed to present at more advanced stages of the hearing and vestibular deterioration. Since then, other authors have described similar lesions in advanced non-genetic hearing and vestibular impairment as well. The purpose of this study is therefore to assess the radiologic investigation using...

Covert-saccades, Dynamic Visual Acuity and Quality of Life

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 co...

Safety and Efficacy of the BrainPort™ Balance Device to Improve Balance in Bilateral Vestibular Hypofunction

The purpose of this study is to determine whether the BrainPort™ balance device is safe and effective in the treatment of balance disorders in patients with Bilateral Vestibular Dysfunction.

Prospective Assessment of Peripheral-vestibular Function After Skull Base Surgery

Due to its localization in the cerebello-pontine angle, the vestibulo-cochlear nerve is at risk to damage during surgery performed nearby. In most cases, peripheral-cochleovestibular hypofunction recovers over the following weeks as the mechanism of damage is rather demyelination than axonal damage. The rate, intensity and extent of recovery of such perioperative peripheral-vestibular damage is not known.

Reactivity of the Vestibular System to Caloric Vestibular Stimulation in Schizophrenia

This study aims to determine if individuals with schizophrenia have greater reactivity to vestibular stimulation than healthy controls. The physiological response of vestibular stimulation will be assessed with electronystagmography, which provides a measure of the intensity of the nystagmus via PSPV. Positive results would suggest greater vestibular system reactivity to vestibular stimulation may be a biomarker of schizophrenia. Pathophysiologically, increased vestibular react...

Prognosis of Vestibular Dysfunction in Patients With Idiopathic Sudden Sensorineural Hearing Loss

Idiopathic sudden sensorineural hearing loss (ISSNHL) refers to idiopathic sensorineural hearing loss of at least 30 dB over at least three test frequencies occurring over a 72-hour period. Vertigo has been considered a risk factor of poor prognosis in patients with ISSNHL. However, the clinical outcome and development of vestibular function in these patients have not been reported yet. We'd like to conduct a study on the problem whether these patients resulted in a complete re...

Vestibular Cochlear Implant Hearing Impaired Child

Cochlear implantation (CI) is a well-known surgical procedure to rehabilitate patients with severe to profound sensorineural hearing loss. Indications for this surgery have expanded in the last 10 years including bilateral CI. Although CI has been described as a safe procedure with few major complications, it may have an adverse effect on the vestibular functions and produce dizziness. Prevalence of postoperative dizziness varies widely in the literature and is said to affect b...

Simultaneous Recordings of Cervical and Ocular Vestibular-evoked Myogenic Potentials

To lower the threshold for clinical application by reducing the testing time for recording vestibular-evoked myogenic potentials (VEMPs), we evaluated whether a simultaneous recording of ocular and cervical VEMPs after unilateral or bilateral stimulation can be achieved without a loss in diagnostic sensitivity.

Non Invasive Vestibular Stimulation in Modulation of Vestibular and Balance Function

Background: Patients with bilateral vestibular hypofunction (BVH) frequently presented with dysequilibrium, dizziness and oscillopsia, leading to increased risk for fall. The mainstream for treatment of vestibular hypofunction remains to be vestibular rehabilitation, yet the effects can be limited in certain cases. Through the application of minimal amount of electrical stimulation, galvanic stimulation can induce polarization in the vestibular nerve, stimulating the saccule, u...


Vestibular Function and Vestibular Rehabilitation in SSHL With Vertigo

To evaluate the vestibular function and vestibular rehabilitation in sudden sensorneural hearing loss(SSHL) with vertigo

VOR Suppression in Non-Gymnast Adults

The researchers hypothesize that there is a correlation between Vestibulo-ocular reflex (VOR) performance and innate athletic skill level. A similar study was conducted in female, young adult gymnasts where a correlation was shown between VOR performance and gymnastic skill level. However, the results from this study did not suggest that VOR differences develop as a result of practice; rather that the differences in VOR may simply allow some individuals to become better perform...

Genotype-phenotype Correlation Study of Presymptomatic and Symptomatic DFNA9 Patients

DFNA9 (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 10 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...

Advances in Vestibular Rehabilitation

Vestibular rehabilitation therapy (VRT) is an exercise-based programme to encourage central nervous system (CNS) compensation for vestibular dysfunction. There is moderate to strong evidence to support VRT as a safe, effective management in reducing dizziness, vertigo, associated falls and improving quality of life in people with a unilateral and bilateral peripheral vestibular disorder. However, the evidence to discriminate between differing forms of treatment is unclear and, ...

A Pilot Clinical Trial of Sympathetic Blockade With Botulinum Toxin Type A to Treat Complex Regional Pain Syndrome (CRPS): a Randomized, Double-Blind, Controlled, Crossover Trial.

Lumbar sympathetic blocks are part of the standard of care for treating patients with sympathetically-maintained pain (e.g. in complex regional pain syndrome or reflex sympathetic dystrophy- RSD). In these patients lower extremity pain can be reduced or abolished temporarily by blocking sympathetic nerves by doing a lumbar sympathetic block. Patients who respond only transiently to sympathetic blocks often choose between potentially dangerous lumbar sympathetic block with neuro...

Vertigo Perception and Quality of Life in Patients After Surgical Treatment of Vestibular Schwannoma

Surgical removal of vestibular schwannoma causes acute vestibular symptoms, including postoperative vertigo and oscilopsia due to nystagmus. In general, the dominant symptom postoperatively is vertigo. Preoperative chemical vestibular ablation can reduce vestibular symptoms postoperatively.
