Who can take part
AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with profound deafness who are getting or already have a cochlear implant (a hearing device placed in the inner ear). It tests hearing training programs after implantation.
- Age
- Over 18 years.
- Sex
- All sexes can join.
- Disease stage
- Deafness that started after learning to speak. Either deafness in one ear with near normal or moderate hearing in the other ear (under 60dB), or profound deafness in both ears.
- Earlier treatment
- People deaf in one ear: implant placed but not yet switched on. People deaf in both ears: already use one cochlear implant and are candidates for a second one.
Main reasons for not taking part
- People under legal protection or guardianship
- Other neurological or neurodegenerative conditions (diseases of the brain or nerves)
- Major changes in the ear bone on CT scan that may block placing the implant
- Not covered by social security

Who can take part
- Age>18
- Unilaterally postlingually-deafened adult cochlear implanted candidates (IC-Uni)
- Person with almost normal or moderate contralateral hearing ( under 60dB)
- Cochlear implanted person whose activation has not yet been performed
- Cochlear implanted subjects with bilateral post-lingual profound deafness, who already benefit from a unilateral cochlear implant and candidates to a bilateral cochlear implant
- Affiliated to social security
Who cannot take part
- Significant anatomical changes on CT scan of the temporal bone that may interfere with the insertion of the cochlear implant
- Subjects with associated neurological or neurodegenerative conditions
- - Subjects under juridical protections or tutelage measure

About the trial
What the trial wants to find out
In the past two decades, the selection criteria for cochlear implantation have been greatly relaxed so that about 60-70% of present cochlear implant (CI) candidates have significant residual hearing in their contralateral ear. However, contralateral hearing is often not considered in rehabilitation programs, mainly due to the lack of scientific evidence on the role it may play. The present project aims to better understand the mechanisms of perceptual learning of CI-processed speech after implantation and to develop and test rehabilitation strategies for CI users.
