The efficacy of formal auditory training in children with (central) auditory processing disorder: behavioral and electrophysiological evaluation

摘要

Long Latency Auditory Evoked Potentials can be used to monitor changes in the Central Auditory Nervous System after Auditory Training. AIM: The aim of this study was to investigate the efficacy of Auditory Training in children with (Central) Auditory Processing Disorder, comparing behavioral and electrophysiological findings before and after training. MATERIAL AND METHODS: twenty nine individuals between eight and 16 years of age with (Central) Auditory Processing Disorder - diagnosed by behavioral tests - were involved in this research. After evaluation with the P300, the subjects were submitted to an Auditory Training program in acoustic booth and, at the end, a new evaluation of (central) auditory processing and a new recording of P300. RESULTS: The comparison between the evaluations made before and after the Auditory Training showed that there was a statistically significant difference among P300 latency values and also among behavioral test mean values in evaluation of (central) auditory processing. CONCLUSION: P300 appears to be a useful tool to monitor Central Auditory Nervous System changes after Auditory Training, and this program was effective in the rehabilitation of the auditory skills in children with (Central) Auditory Processing Disorder.
