Effectiveness of Central Auditory Processing Rehabilitation Program on Dyslexic Student's Auditory Perception

Auditory processing disorder and dyslexia are shown to be related in many researches and they are known to have high comorbidity. Most of dyslexic students have some problems in auditory perception. The purpose of the present study was to investigate the effectiveness of central auditory processing rehabilitation program on the dyslexic students’ auditory perception.

A controlled clinical trial was conducted. The population involved dyslexic elementary school students studying in a learning disorder center in Tehran. Using convenience sampling method, 30 dyslexic students with central auditory processing disorder were selected and were divided into experimental and control groups. Central auditory processing rehabilitation program was designed in 12 steps together with different practices for dyslexic students. Auditory perception test for hearing impaired was conducted in the pretest. The experimental group received 15 sessions of central auditory processing rehabilitation program. Auditory perception test for hearing impaired was conducted in the posttest again and follow up was administered five weeks later.

The data analysis using the multi-variable variance analysis with repeated measures indicated a significant difference between the mean scores of auditory perception in the experimental and in control groups in posttest (P= 0.05).

According to the results, the effectiveness of the rehabilitation program on dyslexic students’ auditory perception was confirmed and follow up showed that effectiveness was stable.
