The comparison of vestibular functions in hearing and hearing impaired populations

This study investigates possible vestibular dysfunctions in the deaf using a typical clinical assessment battery and discerns whether there is a trend between these disorders in meningitic children as compared to children with unknown origins of deafness.

Comparison of Computerized Dynamic Posturography (CDP) results with subjective visual vertical (SVV) test in patients with and without vestibular dysfunction: effects of horizontal headshaking

The goal of the study was to identify what effect headshaking in the horizontal plane has on Computerized Dynamic Posturography results in normals and patients with unilateral vestibular dysfunction. Additionally, the results were compared to results of the dynamic subjective visual vertical test.

Patient perception of disability following acoustic (vestibular) schwannoma removal via gamma knife and microsurgical techniques

This study evaluates patient's short and long-term balance function after microsurgical tumor removal and gamma knife radiosurgery using an unvalidated qualitative questionnaire and the Dizziness Handicap Inventory.

Comparative study of the Gaze Stabilization Test (GST) and the Dynamic Visual Acuity Test (DVAT) for detecting patients with unilateral vestibular dysfunction

This paper compares the use of two diagnostic tests, Gaze Stabilization Test (GST) and the Dynamic Visual Acuity Test (DVAT) to detect unilateral vestibular dysfunction.

Velocity discrimination of angular motion at different frequencies in individuals with normal vestibular function

The purpose of this study was to evaluate discrimination of angular velocity in individuals with normal vestibular function using a newly developed adaptive psychophysical measure. Vestibular psychophysical testing may complement existing clinical measures in diagnosing and treating patients with imbalance.

Ocular vestibular evoked myogenic potentials (oVEMP) using air conducted sound: Effect of body position on threshold

The primary objective of this research study is to determine if various body positions for ocular vestibular evoked myogenic potential (oVEMP) testing demonstrate differentiation of the saccule and utricle through threshold responses.

Dynamic visual acuity following high-frequency head vibration

In order to evaluate high-frequency VOR function, the effects of different types of motion on visual acuity were evaluated in asymptomatic and symptomatic subjects. A new testing protocol of evaluating vestibular function was developed in an effort to enhance current treatment protocols.

Autonomic dysfunction in patients with migrane associated dizziness (MAD)

The goal of this project is to identify what effect vestibular stimulation has on the reaction of the autonomic nervous system, as measured by blood pressure, blood-oxygen saturation levels, and heart rate monitoring, on subjects with migraine associated dizziness (MAD) as compared to healthy non-MAD subjects.

Behavior in pigeons during regeneration

This paper examines the recovery of the vestibular related head posture and balance ability in pigeons during regeneration of the vestibular system following ototoxic insult.

The effects of gravity on the development of otolith organs in the Japanese quail

This paper examines the detailed embryologic development of the otolith organs, part of the vestibular system responsible for balance, in Japanese quail. The data from this study will provide baseline data for comparison with experiments conducted by NASA during space flight.
