Insights
Cortical auditory evoked potentials (CAEPs) like P1 and MMN offer objective insights into hearing and speech rehabilitation for children with cochlear implants (CIs). These measures correlate with rehabilitation progress, aiding evaluation, especially for non-verbal children.
Area of Science:
- Neuroscience
- Audiology
- Speech-Language Pathology
Background:
- Cochlear implants (CIs) are crucial for hearing restoration in children.
- Evaluating auditory and speech rehabilitation effectiveness in pediatric CI users presents challenges.
- Objective measures are needed to complement subjective assessments.
Purpose of the Study:
- To investigate the relationship between cortical auditory evoked potential (CAEP) characteristics and auditory-speech rehabilitation outcomes in children with CIs.
- To assess the utility of objective CAEP measures alongside subjective evaluations.
Main Methods:
- 19 children with CIs underwent CAEP and MMN recordings.
- Auditory and speech abilities were assessed using standardized questionnaires (LEAQ, CAP, SIR, IT-MAIS, MUSS).
- Correlation analyses were performed between CAEP parameters and questionnaire scores.
Main Results:
- CAEP P1 and MMN showed a negative correlation with the duration of CI usage.
- CI duration and auditory-verbal assessment scores were significantly related.
- Questionnaire scores were inversely associated with P1 and MMN latency.
Conclusions:
- CAEP components (P1, MMN) can serve as objective indicators of CI rehabilitation effectiveness.
- These objective measures provide valuable guidance for evaluating progress, particularly in children unable to provide subjective feedback.
Objectives:
This study aimed to explore the correlation between the characteristics of cortical auditory evoked potential (CAEP) of children with cochlear implants (CIs) and auditory and speech rehabilitation performance by an objective evaluation technique and subjective auditory and speech skills measurements.
Methods:
All participants were recruited from Beijing Children's Hospital, Beijing, China. 19 children with CIs had their responses to the CAEP and MMN recorded. The LittlEARs® Auditory Questionnaire (LEAQ), Categories of Auditory Performance (CAP), Speech Intelligibility Rating Scale (SIR), Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS), and Meaningful Use of Speech Scale (MUSS) measures were taken to assess the children's speech and hearing abilities.
Results:
P1 and MMN of CAEP were negatively related to the duration of CI usage. The duration of CI usage and scores of auditory-verbal assessment questionnaires all showed significant relationships. Additionally, scores of these questionnaires were significantly inversely associated with the latency of P1 and MMN.
Conclusion:
P1 and MMN could be used as objective methods to evaluate the effectiveness of hearing and speech rehabilitation in children with CIs. In particular to those who cannot give effectively feedback of auditory and verbal effects, these methods might have a certain guiding significance.
