Treatment by Therapeutic Body Wraps in Children and Adolescents Suffering From Autism With Severe Injurious Behavior.

Overview

Severe injurious behaviors in children with autism spectrum disorder are challenging. First line treatment approaches include behavioral techniques but pharmacotherapy is frequently required despite frequent adverse effects in youths. Therapeutic body wraps has been reported in small series or case reports, but has never been assessed in the context of a randomized controlled trial. The present study is an exploratory, multicenter, randomized, controlled, open label with blinded outcome assessment (PROBE design) trial of the effect of wet versus dry therapeutic body wraps in children presenting with autism spectrum disorder and severe injurious behavior.

Packing therapy has never been assessed, namely in children with severe injurious behavior and autism spectrum disorder. The aim of the present study is to evaluate the beneficial effect of wet versus dry therapeutic body wraps through an exploratory randomized controlled open label blinded outcome assessment approach. The primary objective is the comparison of change in ABC irritability scores from baseline to 3 months between the two groups. According to the potential recruitment, we plan to recruit 30 subjects in each group. This sample size could allow us to detect a minimum effect size of 0.74 between the 2 groups (considered large in literature) with a power of 80% (two-sided test and type I error of 5%). As described elsewhere, wet or dry session will be organized through twice-a-week sessions for a 3-month duration. Comparison in primary outcome (ABC irritability score) between the 2 groups will be performed using Analysis of Covariance (ANCOVA) adjusted for the baseline value. The standardized difference (effect size) will be computed taking into account the adjustment for baseline and its 95% confidence interval will be estimated using a bootstrap resampling. The validity of the ANCOVA model will be checked by examining the model residuals. The same methodology will be used for the secondary outcomes.
