Insights
This study shows that an auditory training protocol improved auditory skills in children with Central Auditory Processing Disorder (CAPD), enhancing their perception of these abilities.
Area of Science:
- Audiology
- Neuroscience
- Pediatrics
Background:
- Central Auditory Processing Disorder (CAPD) affects auditory skills crucial for development.
- Early intervention is key for managing CAPD in children.
- Standardized assessments are vital for diagnosing and tracking CAPD progression.
Purpose of the Study:
- To introduce and evaluate an auditory training protocol for children diagnosed with CAPD.
- To assess the efficacy of the protocol in improving specific auditory processing skills.
- To measure changes in self-perceived auditory abilities post-intervention.
Main Methods:
- Nine children (ages 9-12) with normal hearing participated.
- Initial assessments included behavioral CAP tests and a self-perception questionnaire.
- An eight-session auditory training protocol with four distinct activities was administered.
- Post-training assessments replicated the initial behavioral tests and questionnaire.
Main Results:
- Statistically significant improvements were noted in key CAP behavioral tests, including Dichotic Digit Test (DDT) and Competing Dissyllable Test (SSW).
- Improvements were observed in binaural integration, figure-ground, and temporal resolution skills.
- Participants reported enhanced self-perception of their auditory abilities after training.
Conclusions:
- The auditory training protocol demonstrated effectiveness in improving auditory skills in children with CAPD.
- While not achieving complete normalization, the protocol led to measurable gains in auditory processing and self-perception.
- This protocol offers a promising approach for auditory rehabilitation in pediatric CAPD.
Purpose:
To present an auditory training protocol in children with Central Auditory Processing Disorder (CAPD).
Methods:
The study included nine children aged from 9 to 12, with five females and four males. Only children with auditory thresholds within the normal range and bilateral type A tympanometric curves were selected. Initially, a behavioral assessment of Central Auditory Processing (CAP) was conducted, and a self-perception questionnaire was administered. Subsequently, eight sessions of auditory training were conducted following a defined protocol with four specific activities per session, aimed at training distinct auditory skills. In a third phase, a new CAP behavioral assessment was carried out, and the questionnaire was reapplied.
Results:
The quantitative analysis of the pre- and post-training behavioral tests showed statistically significant improvements in the Left Dichotic Digit Test (DDT), the Left Competing Dissyllable Test (SSW), the Left Synthetic Sentence Identification with Ipsilateral Competing Message Test (SSI), and the Random Gap Detection Test (RGDT). An improvement in auditory behavioral perception of the participants was also observed, as indicated by the self-perception questionnaire responses.
Conclusion:
Although the auditory training protocol did not result in complete normalization in the Central Auditory Processing (CAP) Behavioral Assessment tests, an improvement in the auditory skills of binaural integration, figure-ground and temporal resolution of participants was observed, as well as in their personal perception of these abilities.
