Vestibular Implants Tested in Human Subjects
Vestibular Disorder, Vestibular Ataxia, Vestibular Loss, Bilateral
About this trial
This is an interventional basic science trial for Vestibular Disorder focused on measuring eye movements, perception, vestibular, dizziness, sensory integration, prosthesis
Eligibility Criteria
Inclusion Criteria:
- scheduled for cochlear implant CI surgery because of deafness
- minimum of five year history of documented absence of auditory & vestibular function, based on review of their audiograms & vestibular tests
- Specific vestibular criteria are: peak ice water caloric response of less than 3 deg/s for each ear; yaw VOR time constant < 3.0 sec and gain < 0.25; and reduced head impulse gain (<0.25) for all canal planes.
- Specific audiographic criteria: 80dB or greater sensorineural hearing loss in both ears
Exclusion Criteria:
- pregnant
- not scheduled for cochlear implant/vestibular implant surgery
- unable to walk 50m
- other neurological disorder (other than migraine), otologic disease (other than presbycusis)
Sites / Locations
- Massachusetts Eye and Ear Infirmary
- Ohio State University
- Universite de Geneve Hospital (UNIGE)
