[Have we made progress in the development of a vestibular implant?].

The concept of a vestibular implant to restore balance in patients suffering from bilateral loss of function is similar to that of a cochlear implant. Motion sensors will capture head movements and this information will be transmitted to the central nervous system via electrodes implanted in the vestibular system. However, several key questions must be answered before such prosthesis could be used in humans. One is to restore a baseline neural activity in the system that can be then adequately modulated by the prosthesis, without causing unbearable symptoms. We showed that this is possible in human. This is an important prerequisite for the feasibility of a vestibular implant.
