This exploratory analysis examined articulation and phonological processing in 21 children aged 4.7–13.1 years with cochlear implants and deficits in these skills, enrolled in a 2-year waitlist-deferred randomized controlled trial of image-guided cochlear implant programming (IGCIP). Articulation improved relative to age norms over time, whereas phonological processing did not. IGCIP had no statistically significant effect on either outcome during the first year. However, children who received IGCIP in that year showed larger, clinically meaningful articulation-score improvements than those who did not, a finding requiring confirmation in a larger sample.
Key findings
- Articulation, but not phonological processing, improved relative to age norms over time.
- IGCIP had no statistically significant first-year effect on articulation or phonological processing.
- Children receiving IGCIP in the first year had larger, clinically meaningful articulation-score improvements than those not receiving it.
Why it matters
The findings distinguish the developmental course of articulation from phonological processing in children with cochlear implants, suggesting these outcomes may not change in parallel. The possible articulation benefit associated with IGCIP is clinically relevant but remains exploratory: the analysis involved a small subset, and the first-year treatment effect was not statistically significant.
What to keep in mind
The analysis included only 21 children from the trial, and the exploratory IGCIP findings were not statistically significant in the first year.
