Summary
Cochlear implants benefit deaf children with motor development delay (MDD) as much as those without. This study shows similar speech perception and intelligibility improvements in both groups after implantation.
Area of Science:
- Audiology
- Pediatric Medicine
- Neurosurgery
Background:
- Cochlear implantation is increasingly considered for deaf children with additional disabilities.
- This study investigates outcomes in children with and without motor development delay (MDD).
Purpose of the Study:
- To evaluate the impact of cochlear implants on speech perception and intelligibility in deaf children with and without MDD.
Main Methods:
- A cohort study compared outcomes in 262 deaf children (pre-lingual profound hearing loss).
- 28 children had MDD (GMFC levels 1-3); severe motor or cognitive delays were excluded.
- Speech perception (CAP) and intelligibility (SIR) were assessed pre-surgery and 24 months post-activation.
Main Results:
- Cochlear implants significantly improved CAP scores in all children (P=0.001).
- Post-surgery CAP scores were 5.03 for MDD and 5.77 for NMD children.
- Post-surgery SIR scores were 2.53 for MDD and 2.66 for NMD children.
- No significant differences in CAP or SIR scores were found between MDD and NMD groups (P>0.05).
Conclusions:
- Children with hearing loss and concomitant MDD benefit from cochlear implantation.
- Outcomes are comparable to those with normal motor development, supporting cochlear implant candidacy for this population.
