Summary
Electrically evoked stapedius reflex thresholds (eSRT) effectively create cochlear implant programs for children. This method showed high correlation with behavioral testing and positive parent feedback, proving viable for difficult-to-test pediatric populations.
Area of Science:
- Audiology
- Biomedical Engineering
- Speech-Language Pathology
Background:
- Electrically evoked stapedius reflex thresholds (eSRT) show promise for programming cochlear implants in adults.
- Behavioral testing for cochlear implant programming can be challenging in pediatric populations.
Purpose of the Study:
- To evaluate the efficacy of eSRT for programming cochlear implants in children.
- To compare eSRT-derived programs with behaviorally derived programs in pediatric cochlear implant users.
Main Methods:
- Seven children with cochlear implants participated.
- Most comfortable levels (MCL) were determined using both eSRT and behavioral testing.
- Parental feedback was collected on program preference.
Main Results:
- A high correlation (r(2) = 0.789) was found between eSRT and behavioral MCLs.
- No significant difference was observed between the two programming methods.
- Parents reported the eSRT program was equally or more effective than the behavioral program.
Conclusions:
- eSRT is a viable and safe method for programming cochlear implants in children, especially those difficult to test.
- Further research is recommended for initial fitting periods in new cochlear implant users.
