Conditions

Bilateral Cochlear Implants, Unilateral Cochlear Implants

Brief summary

This is a prospective research study talking place at University hospital of Dijon and requiring the inclusion of 20 healthy subjects, 10 patients with unilateral cochlear implants and 10 patients with bilateral cochlear implants to carry out: * an audio-vestibular examination, * a videonystagmoscopic study, * a posturography study and * a movement study. The aim of the study is to evaluate the impact of binaural audition on postural performance and orientation.

Interventions

OTHERAudio-vestibular examination

Vestibular tests (videonystagmoscopy and head video impulse test), the tonal and vocal audiogram and the localigramme to the cochlear implanted subjects. Tonal audiometry and localigramme to the healthy subjects.

OTHERVideonystagmoscopic study

Rotating sound stimulation on a rotatory armchair and a laborer of Fukuda with sound stimulation and questionary before and after examination.

OTHERPosturographies study

(stabilometry, sensory preferences, indications of energy consumption) with stereophonic stimulation and questionnaire before and after the examination.
