ABSTRACT
Purpose
Analyze and correlate the auditory performance in the evaluation stage in the chosen software and electrophysiological responses pre and post computer-based auditory training.
Methods
This is a longitudinal, comparative, clinical and experimental study, performed after the approval of the ethics committee. The sample consisted of seven children, aged 7 to 8 years and 11 months, from both genders, diagnosed with auditory processing disorder. The therapeutic intervention was based on the training with the Escuta Ativa® software and composed of 12 sessions, perforned twice a week, lasting approximately 30 minutes each. The score in the evaluation stage in the chosen software and the findings of the electrophysiological measurement on Long-Latency Potential Evoked Auditory, specifically P3 component, pre and post-training, were analyzed through an adequate statistical study.
Results
Among the three stages of the evaluation by the software, there was no statistically significant post-training result. As for the P3 component, 3 out of the 4 children started to have it post-intervention therapy. In the search for correlation between behavioral and electrophysiological results, there was no statistical significance in either moments of the evaluation.
Conclusion
It was not possible to verify a significant difference between the pre and post-training periods in the evaluation stage of the software itself, showing the need for further studies to verify the use of this evaluation tool in a clinical setting. An effect of post-training plasticity with the appearance of P3 component was noted in some children. There was no correlation between the evaluation steps by the software and the electrophysiological measurement.
