Summary
Brief summary
The current project proposes a multi-center prospective follow-up cohort study aiming to realize an international framework to classify human functioning and disability in Cochlear Implant (CI) recipients using a standardized ICF framework. For this, ICF qualifiers which denote the magnitude of the level of health or severity of the problem will be quantified to enable comparison of data across countries and health-care disciplines. Adult subjects (=18 years old) eligible for cochlear implantation, considering the local criteria of reimbursement, will be assessed one month preoperatively and six months post the activation of the speech processor using three audiological examinations, evaluating the participants' localization abilities, speech recognition and hearing thresholds, and six questionnaires, each evaluating different aspects of daily life functioning and disability in hearing-impaired persons.
