Using cortical auditory-evoked potential responses to verify the objective benefit of aural rehabilitation in adult cochlear implant users

Cortical auditory-evoked potential (CAEP) responses are used clinically to assess auditory processing and support cochlear implant (CI) mapping procedures post-implantation. This study aims to examine CAEP responses as an objective measure of neurophysiological changes following a structured Aural Rehabilitation Program (ARP) in long-term adult CI users, with poor baseline speech perception performance....

CAEPs show promise as an objective tool for verifying rehabilitation benefit in adult CI users; audiologists working in CI programs may consider integrating CAEP measurement into outcomes tracking, though broader validation is still needed before routine adoption.

Objective, electrophysiological confirmation of aural rehabilitation benefit could strengthen clinical decision-making, guide therapy intensity, and provide measurable outcomes data for CI programs.

1. 01CAEPs (brain responses to sound measured from scalp electrodes) were used to objectively measure rehab benefit in adult CI users.
2. 02Objective measures could reduce reliance on self-report and behavioral tests alone.
3. 03Study focused on post-implantation aural rehabilitation outcomes, a recognized gap in CI clinical protocols.
4. 04Published in Frontiers in Neuroscience; evidence level and sample size will determine generalizability.
5. 05Could inform standardization of CI rehabilitation outcome measurement if replicated in larger studies.
