Auditory-cognitive training for adult cochlear implant recipients: a study protocol for a randomised controlled trial

Area of Science:

• Neuroscience
• Audiology
• Cognitive Psychology

Background:

• Adults undergoing cochlear implant surgery often experience a decline in cognitive function.
• There is a critical need for effective therapies to enhance cognitive abilities post-surgery.
• This research focuses on improving memory and thinking skills in this population.

Purpose of the Study:

• To evaluate the efficacy of at-home computer-based brain training in adults receiving their first cochlear implant.
• To compare adaptive computerized cognitive training with a non-adaptive (placebo) version, alongside auditory training.
• To assess improvements in cognition, sound and speech perception, mood, and quality of life.

Main Methods:

• A single-blind, head-to-head, randomized controlled trial (RCT) design.
• Participants aged 18+ meeting cochlear implant criteria were recruited.
• Intervention involved auditory training plus either adaptive or non-adaptive computerized cognitive training.

Main Results:

• The trial will determine if combined auditory and adaptive cognitive training yields greater improvements compared to placebo.
• Outcomes measured include cognitive function, auditory perception, speech understanding, mood, and quality of life.
• Results are expected to clarify the benefits of specific cognitive training protocols.

Conclusions:

• The findings are anticipated to inform clinical practice for adult cochlear implant recipients.
• This research may lead to new therapeutic strategies for post-cochlear implant cognitive rehabilitation.
• The study aims to provide evidence-based recommendations for enhancing patient outcomes.
