Filter by:The aim of this study was to investigate of the effect of web-based System with oculomotor and optokinetic stimulation on rehabilitation in vestibular hypofunction. In the literature, studies on vestibular rehabilitation in unilateral hypofunction are very limited and there is no study about it.
The aim of this study was to compare the efficacy of home based vestibular rehabilitation program, posturographic biofeedback training and whole body vibration therapy on balance, fall risk, functional mobility, vertigo symptom severity and functions in patients with unilateral vestibular weakness.
This study evaluates the use of vibrotactile feedback to traditional vestibular treatment protocols. Half the patients will have vibrotactile feedback added to their treatment protocols while the other half will undergo traditional vestibular treatment without vibrotactile feedback.
The purpose of this study is to explore the diagnostic values associated with both a positive and negative Skull Vibration Induced Nystagmus Test (SVINT) performed in room light (with fixation). The hypotheses include: 1. A positive room light SVINT will be identified in individuals with moderate to severe vestibular asymmetries. 2. A positive room light SVINT will be present when 10 beats or more (counted over 10 seconds) of nystagmus are found with fixation blocked.
Background: - Neurofibromatosis type II (NF2) is associated with tumors of the nerves, brain, and spinal cord. Most people with NF2 develop vestibular schwannomas, or tumors on the hearing and balance nerves. As they grow, vestibular schwannomas can cause hearing loss and balance problems. If they grow very large they can cause more serious problems, such as seizures, loss of eyesight, weakness, speech problems, and problems with the sense of touch. More research is needed into NF2 because researchers do not completely understand why these tumors occur or what makes them grow over time. - Currently, tumor size is measured with magnetic resonance imaging (MRI) scans. However, MRI scans cannot predict how fast a tumor will grow. By using positron emission tomography (PET) scanning, researchers hope to be able to predict sudden growth spurts of tumors associated with NF2 and develop better treatment methods for this type of cancer. Objectives: - To use magnetic resonance imaging and positron emission tomography to better understand the growth of brain tumors in people with neurofibromatosis type II. Eligibility: - Individuals between 18 and 50 years of age who have been diagnosed with NF2 and have at least three untreated intracranial tumors. Design: - This study requires an initial set of outpatient visits to the NIH Clinical Center that will last 7 to 10 days. - Participants will have a physical and neurological examination and blood tests at the first visit. Participants will then have the following imaging studies to examine the tumors: - MRI scans of the brain - PET scans of the brain, combined with a computed tomography (CT) scan. The PET scans will be performed on separate days. Different contrast agents will be used for both scans, so researchers will inform participants if they need to fast or follow other procedures before having the scan. - After the initial imaging studies, participants will have additional MRI scans every 6 months for 2 years to track tumor growth.
This study is being done because the investigators would like to know how effective the Liberatory maneuver is in treating benign paroxysmal positional vertigo (BPPV).
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.
This study will try to identify the genetic causes of hereditary hearing loss or balance disorders. People with a hearing or balance disorder that affects more than one family member may be eligible for this study. They and their immediate family members may undergo some or all of the following procedures: - Medical and family history, including questions about hearing, balance and other ear-related issues, and review of medical records. - Routine physical examination. - Blood draw or buccal swab (brushing inside the cheek to collect cells) - Tissue is collected for DNA analysis to look for changes in genes that may be related to hearing loss. - Hearing tests - The subject listens for tones emitted through a small earphone. - Balance tests to see if balance functions of the inner ear are associated with the hearing loss In one test the subject wears goggles and watches moving lights while cold or warm air is blown into the ears. A second test involves sitting in a spinning chair in a quiet, dark room. - Photograph - A photograph may be taken as a record of eye shape and color, distance between the eyes, and hair color. - Computed tomography (CT) and magnetic resonance imaging (MRI) scans - These tests show the structure of the inner ear. For CT, the subject lies still for a short time while X-ray images are obtained. For MRI, the patient lies on a stretcher that is moved into a cylindrical machine with a strong magnetic field. The magnetic field and radio waves produce images of the inner ear. The radio waves cause loud thumping noises that can be muffled by the use of earplugs.
