"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...
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.
The aim of this study is to assess risky infants (or diagnosed infants) with Infant Motor Profile, and analyze interrater and intrarater reliability of this test.
Do migrainous vertigo patients have more pathology in their vestibular system than migraine patients without vertigo? The aim of this study is to compare the vestibular system of migraine patients with and without vertigo in the symptom-free period by vestibular function tests, videonystagmography, vestibular evoked myogenic potentials, and subjective visual vertical.
Recently, new clinical testing of saccular and utricular function have been developed and validated, the so-called vestibular-evoked myogenic potentials - VEMP (Brantberg et al. 2009, Cornell et al. 2009, Curthoys 2010, Manzari et al. 2012). Among them, the cervical VEMP (cVEMP) are short-latency electromyographic (EMG) modulations of the contracted sternocleidomastoid muscles in responses to vibration applied on the forehead. The clinical literature suggests that cVEMP are alm...
Nasopharyngeal carcinoma (NPC) is usually treated with chemoradiotherapy. While the effects of this treatment on cochlear function is well characterized, its effect on vestibular function is not well studied. In this study the investigators will study the vestibular function of 50 patients undergoing chemoradiotherapy for NPC both before and after treatment in order to better define its effects. All patients will undergo a validated questionnaire (dizziness handicap index), ...
Objective: Assess the effect of caffeine in the following vestibular function tests: Cervical Vestibular Evoked Potential (cVEMP), Ocular Vestibular Evoked Potential(oVEMP) and Caloric Test. Methods: Randomized, prospective triple-blind, placebo controlled clinical trial. All participants underwent otoscopy, tympanometry, responded to the Profile of Mood State (POMS), submitted to the cVEMP, oVEMP and caloric tests. After that they received placebo or caffeine capsule (3...
Myasthenia gravis is an autoimmune disorder of neuromuscular transmission, characterized by fluctuating muscle weakness and fatigability. In isolated ocular myasthenia, when only the extraocular muscles are involved, most common ancillary tests, such as acetylcholine receptor autoantibodies and repetitive nerve stimulation, are often negative. A simple, quick and non-invasive test for ocular myasthenia based on ocular vestibular evoked myogenic potentials (oVEMP) was recently ...
We will conduct a faculty development workshop with intent to improve interrater reliability and rater accuracy. Outcomes will include interrater reliability, accuracy, and workshop evaluations.
Benign Paroxysmal Positional Vertigo (BPPV) is the most frequent cause of vertigo of peripheral vestibular origin with life time incidence of 2.4%. BPPV is characterized by bouts of acute whirling vertigo lasting less than one minute provoked by changes in head position in relation to the gravitational vector. The vertigo is accompanied by typical rotational or horizontal nystagmus that is often demonstrated by the Dix-Hallpike maneuver and less frequently by testing for positi...
Spontaneous myogenic oscillations will be studied under general anesthesia using finger photoplethysmography. This pilot study will explore potential physiological conditions that will effect the amplitude and/or frequency of myogenic oscillations.
The ASA-PS classification, a subjective classification system of the patients' preoperative health status, contains a certain problem concerning its interrater reliability. A comparison between anesthesiologic and surgical assessment of the preoperative patient condition has not yet been extensively investigated. The aim of this study is to examine the latter in a prospective, monocentric, observational study.
The aim of the study was to determine construct validity, discriminant validity and intra- and interrater reliability of the Selective Control of the Upper Extremity Scale (SCUES).
Overall, the purpose of this dissertation research is to investigate trunk control in young children with DS. This will be done in three studies: 1. The purpose of the first study is to determine the reliability of the SATCo in young children with DS. The hypothesis is that the SATCo will demonstrate good (κ > 0.8) interrater and intrarater reliability. 2. The purpose of the second study is to examine the validity of the SATCo with the GMFM-66 and de...
Multimodal Evoked potentials (mmEP) reflect disease course of multiple sclerosis (MS) and are potentially suited as a biomarker for disease progression. The acquisition of evoked potentials (EP) in this observatory trial is to evaluate the feasibility and test-retest reliability of motor and somato-sensory EP (MEP and SSEP) in an international multicenter setting in healthy subjects and subjects with multiple sclerosis (MS).
To investigate which treatment option (corticosteroid treatment alone or combined corticosteroid treatment and vestibular rehabilitation) is the most effective in patients diagnosed with vestibular neuritis.
To prospectively evaluate the tools, environment and resources to compare the effectiveness of two different standard of care vestibular rehabilitation approaches in a military cohort with post-concussive vestibular symptoms.
OBJECTIVES: I. Evaluate whether vestibular rehabilitation training is of value in reducing anxiety symptoms in patients with panic disorder with or without agoraphobia who have vestibular dysfunction as identified by clinical vestibular tests.
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 v...
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.
Nearly 2 out of 3 patients with Alzheimer's disease (AD) experience problems with balance and mobility, which places such patients at increased risk of falling. The vestibular (inner ear balance) system plays an important role in balance stability, and vestibular therapy (VT) is well-known to improve balance function in healthy older adults. In this study, the investigators will conduct a first-in-kind randomized clinical trial to evaluate whether vestibular therapy improves ba...
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...
To evaluate the vestibular function and vestibular rehabilitation in sudden sensorneural hearing loss(SSHL) with vertigo
Initially, a written consent was obtained from each participant. Then they became familiar with the procedure. For intrarater reliability, the first rater assessed the strength of pinch grip, elbow flexion and shoulder abduction in three different sessions at short intervals on same day in same environmental conditions. All the assessments were performed on the same day in three sessions. Assessment duration of all the sessions was 5 minutes. For inter-rater reliability, Befo...
