Filter by:A randomized controlled trial to assess the efficacy of an app-assisted vestibular rehabilitation in increasing adherence to VR and treatment outcomes
This 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.
Randomized controlled parallel designed clinical study aimed to compare vestibule depth gain and dimensional changes of wound area in individuals who underwent vestibule deepening surgery using diode laser and conventional technique
The purpose of this study was to evaluate vestibular function in children with idiopathic scoliosis as a possible cause of etiopathogenesis of its diagnose.
In this study the investigators propose to apply cognitive training, which has been largely used in the realm of age-related cognitive decline, dementia, and Alzheimer's disease, in a novel clinical context to individuals with vestibular impairment. In prior work the investigators observed that individuals with vestibular loss have evidence of spatial cognitive impairment. The investigators plan to evaluate the preliminary efficacy and feasibility of a cognitive training program in a sample of participants with chronic vestibular impairment who display deficits in spatial ability. The cognitive training program will focus on visuospatial skills and will be used as an adjunct to traditional vestibular physical therapy (VPT).
Study on patients with CNS infections.
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 between 2% - 47%.
"Test-Retest Reliability of ocular vestibular evoked myogenic potentials (oVEMPs) across different electrode montages." The purpose of this project is to compare the response characteristics of the ocular vestibular evoked myogenic potential in patients grouped by decade (i.e. 20's-90's) using two different recording montages and two different stimulus types (i.e. air and bone conducted sound). The long-term goal is to increase the sensitivity and specificity of the oVEMP when used clinically to identify vestibular disorders affecting the utricle and superior portion of the vestibular nerve.
Persons exposed to infrasound - frequencies below 20 Hz - describe a variety of troubling audiovestibular symptoms, but the underlying mechanisms are not understood. Recent animal studies, however, provide evidence that short-term exposure to low frequency sound induces transient endolymphatic hydrops. The existence of this effect has not been studied in humans. The long-term objective of this research is to identify a possible mechanism to describe the effects of infrasound on the human inner ear. The central hypothesis of the proposed study is that short-term infrasound exposure induces transient endolymphatic hydrops in humans. This will be tested by performing electrophysiologic tests indicative of endolymphatic hydrops among normal hearing individuals before and immediately after a period of infrasound exposure. Recordings of infrasound generated by wind turbines in the field have been established and calibrated by this team of engineers, otologist, and hearing and balance scientists. An infrasound generator reproduces the acoustic signature based on these field recordings. Aim 1: Determine the effect of infrasound on the summating potential to action potential (SP/AP) ratio on electrocochleography (ECoG). Hypothesis 1: Infrasound exposure will cause a reversible elevation of the SP/AP ratio. Aim 2: Determine the effect of infrasound on the threshold response curves of ocular and cervical vestibular evoked myogenic potentials. (oVEMP and cVEMP). Hypothesis 2: Infrasound exposure will cause elevation of the oVEMP and cVEMP thresholds at the frequency of best response. Successful completion of the aims will provide evidence for a possible mechanism of the effect of infrasound on the inner ear. This understanding will benefit individuals exposed to environmental infrasound and those in regulatory, research, and advocacy roles when crafting interventions and future policy.
