[Computer-based auditory training for hearing rehabilitation of adult cochlear implant users]

Digitalization has become a part of everyday life and digital applications offer an opportunity to promote health. In Germany, hearing rehabilitation after cochlear implantation (CI) typically takes place in specialized audiology centers. However, a variety of new auditory training programs have been developed and although most are for hearing aid users, some are suitable for CI patients. The purpose of this study is to give an overview of CBAT schedules and their effectiveness.

Currently available English and German CBAT programs for adult CI users identified in searches of Google, Google App Store, and Google Play Store were analyzed. A systematic literature search on studies dealing with CBAT in adult CI recipients from 2000 to 2019 was performed in PubMed, LIVIVO, and Google Scholar.

German and English CBAT for adult hearing aid and CI users are generally intended to complement face-to-face therapies. The content of the programs differs primarily in terms of complexity and quantity of tasks, graphic design, allowed time and the device used. In contrast to the nine available German programs, some of the English CBAT include advanced concepts of adaptivity and feedback. Studies on the effectiveness of CBAT have mainly been conducted for the English versions and generally analyze only individual therapeutic subfunctions. All investigations show a short-term improvement of the auditory subfunction shortly after training. Unfortunately, the quality of the studies is low and follow-up results are only available in two cases.

CBAT programs might be an effective option for auditory rehabilitation in CI patients. However, suitable German-language programs conceived as an alternative to face-to-face training and studies on longterm effects of CBAT are still lacking.
