Bilateral loss of the vestibular (BV) function leads to chronic imbalance and oscillopsia. This condition has a significant negative impact on quality of life, indicating a need to remedy the lack of effective treatment. The concept of the vestibular implant (VI) has emerged, it consists of a modified cochlear implant stimulator with one up to three additional electrodes positioned in contact with the vestibular nerve. An external processor, fed with motion information captured by a head-fixed motion sensor, is connected to the implanted stimulator. Finally motion modulated electrical stimulation is delivered to the vestibular nerve. Up to now, 13 patients with a BV loss have been implanted. We demonstrated that it is possible to significantly improve or in certain cases to normalize the vestibulo-ocular reflex (VOR) gains. We further showed that the vestibulo-collic reflex could be elicited and that controlled postural responses could be obtained. Finally, the dynamic visual acuity (DVA) while walking has been significantly improved, or even normalized, in 6 subjects. This was the first demonstration of a functional rehabilitation. The presented results reflect the potential of the VI towards a clinically useful device. Moreover, by providing selective stimulations of the vestibular system, the VI opens doors to push the vestibular research beyond the traditional boundaries.
