Research questions the effectiveness of stimulation rate changes on perception in cochlear implant users, indicating a need for caution in clinical practice.
Research exploring the impact of stimulation rate modifications on perception in cochlear implant users continues to expand. The existing body of research remains contradictory, making it difficult to establish a clear consensus that could inform clinical recommendations. In this context, this article aims to question the usefulness of such adjustments as a clinical intervention beyond the initial fitting, particularly for optimizing non-speech processing. To do so, we combined an overview of the existing literature on the effects of stimulation-rate changes on speech and non-speech processing with a discussion of observational data. The current evidence base is sparse, often contradictory, and affected by interoperability challenges that limit cross-study comparability. Consequently, it is not possible to formulate robust, evidence-based clinical recommendations at this time. Clinicians should be cautious about implementing stimulation-rate adjustments beyond the initial fitting and should wait for more robust evidence to emerge before considering such changes.
