1. A Study to Evaluate Electrophysiological Measurements in Cochlear Implant Patients

   Rochester, Minn.

   The purpose of this study is to perform electrophysiological (inner ear) measurements to assess hearing function in cochlear implant patients.

    

    

2. A Study to Determine the Feasibility of Doppler Ultrasound of Large Arterial Systems of the Brain as Vascular Involvement Markers in Presbyacusis and Presbyvestibulopathy

   Jacksonville, Fla.

   The purpose of this study is to benchmark the feasibility of carotid artery biomechanical analysis and vertebral-basilar Transcranial Doppler (TCD) as markers of vascular involvement in presbyacusis and presbyvestibulopathy.

3. Hearing Genomics

   Rochester, Minn.

   Aims, purpose, or objectives:

   1) Develop hypotheses related to how the human genome and genetic variants affect hearing loss in children and adults.

   2) Understand phenotypes of hearing loss on a deeper level by combining and analyzing information from audiometric, genetic, and radiologic data.

   3) Explore genetic variants with an unknown significance to develop an understanding of their potential significance and explore other genes may influence an individual's hearing ability.

4. A Study to Evaluate A Tinnitus Implant System to Treat Chronic Severe Tinnitus

   Rochester, Minn.

   The purpose of this study is to evaluate the feasibility of implementing a novel Tinnitus Implant System for suppression of chronic intractable tinnitus.

5. Study to Compare Middle Ear Mechanics in Individuals with Unilateral Otosclerosis, and Unilateral and Bilateral Cochlear Implant Recipients

   Rochester, Minn.

   The purpose of this study is to measure the changes in the middle ear mechanics or the transfer function in cochlear implant recipients and compare those changes with the middle ear transfer function measured in individuals with unilateral otosclerosis.

6. A Study to Determine if the Video Head Impulse Test has Sufficient Sensitivity and Specificity for Adding to Routine Clinical Practice

   Rochester, Minn.

   The present study is designed to examine the sensitivity and specificity of the video head impulse test.  The testing performed for this study is routinely ordered by referring physicians and widely used in clinical practice. It is a purpose of this study to determine whether the video head impulse test has sufficient sensitivity and specificity to warrant adding this device to routine clinical practice. 

7. Study of Auditory Function through Intra- and Post-operative Measurements

   Rochester, Minn.

   The purpose of this study is to determine if electrocochleography (ECochG) measurements performed during cochlear implant surgery can be used to monitor cochlear structures and minimize electrode insertion trauma.

8. A Study to Evaluate Ability of Hearing Aids and Wearable Sensors to Detect Falls

   Rochester, Minn.

   The purpose of this study is to evaluate the sensitivity and specificity of Livio© hearing aids and Apple Watch© to detect falls when subjects with normal/abnormal vestibular function experience controlled, postural disturbances on a treadmill. We will also assess the interaction mechanism of vestibulocolic and vestibulospinal reflex in fall prevention.

9. A Study to Evaluate Impedance Monitoring in Cochlear Implants

   Rochester, Minn.

   The purpose of this study is to determine changes in cochlear implant electrode impedances as a function over a period of time.

10. A Study to Evaluate the Effect of Electrode Impedance Fluctuations on Cochlear Implants

    Rochester, Minn.

    The purpose of this study is to determine the effect of fluctuating electrode impedances on speech perception in cochlear implants.
