Abstract:
Bilateral loss of vestibular sensation from injuries of vestibular hair cells causes individuals suffering poor vision during head movement, postural instability, chronic disequilibrium, and cognitive distraction. A vestibular prosthesis analogous to cochlear implants but designed to modulate vestibular nerve activity during head movement should improve quality of life for these chronically dizzy individuals. An implantable prosthesis that partly restores normal activity on branches of the vestibular nerve should improve quality of life for individuals disabled by this disorder. There have been many efforts to develop and restore 3-dimensional angular vestibule-ocular reflex and the Johns Hopkins vestibular neuro-engineering laboratory has been developing a head-mounted multichannel vestibular prosthesis that restores sufficient semicircular canal function to partially recreate a normal 3-dimensional angular vestibulo-ocular reflex. In this review, their results are described.
