Hearing loss profoundly affects individuals’ quality of life, limiting participation in social, professional, and communicative domains. Cochlear implants (CIs) restore access to auditory input for postlingually deafened adults, but understanding speech through a CI relies heavily on neuroplastic adaptation. While many CI users regain the ability to follow conversations in quiet environments, speech-in-noise (SPiN) perception remains a major challenge. Music training has been shown to enhance shared auditory and cognitive neural networks and to improve auditory-motor coupling, which may facilitate SPiN perception in both normal-hearing and hearing-impaired individuals. These findings provide a rationale for using multi-modal Neurologic Music Therapy (NMT™) to support auditory rehabilitation in adult CI users. However, research to date has focused primarily on passive music listening, leaving the effects of structured, active music training largely unexplored. This randomized controlled clinical trial investigates the effects of short-term targeted multi-modal music training on SPiN and working memory (WM) in postlingually deafened adult CI users. Additionally, the study examines neurophysiological mechanisms of change using electroencephalography (EEG), specifically focusing on alpha oscillation modulations during auditory-cognitive tasks. Thirty-six adult CI users are enrolled in a 4-week NMT™ training program, randomly assigned to pitch, rhythm, or timbre-focused conditions. Behavioral outcomes are assessed pre- and post-training using the sentence-final-word-identification-and-recall (SWIR) test; EEG is recorded during all SWIR tasks. Presented will be behavioral results from 36 participants on SPiN perception and WM performance between training types. So far, only behavioral data have been analyzed; EEG analysis is ongoing and will be reported as available. Early findings, based on a small and heterogeneous sample, show promising trends. Further EEG analysis is expected to provide deeper insight into neuroplastic changes, including modulation of alpha activity, potentially supporting music-based strategies to enhance auditory performance and life quality in CI users.
