Abstract
Objectives:To determine the effectiveness of auditory integration training (AIT) or other methods of sound therapy in individuals with autism spectrum disorders (ASD).
Study design:We completed a systematic review of randomised controlled trials (RCTs) of adults or children with ASD treated with auditory integration therapy (AIT) or similar sound therapies. Meta-analysis was attempted.
Results:Six RCTs of AIT, including one cross-over trial, were identified with a total of 171 participants aged 3-39 years. Four trials had fewer than 20 participants. Seventeen different outcome measures were used. Only two outcomes were used by three or more studies. Meta-analysis was not possible due to very high heterogeneity, or presentation of data in unusable forms. Three studies did not demonstrate any benefit of AIT over control conditions. Three studies reported improvements at 3 months for the AIT group for total mean scores of the ABC, which is of questionable validity. Of these, one study also reported improvements at 3 months in the AIT group for ABC subgroup scores. No significant adverse effects of AIT were reported.
Conclusion:At present there is not sufficient evidence to support its use.
