Weighted vests used as part of sensory integration therapy may not work for all children with autism spectrum disorders (ASD). This review article examined seven studies using weighted vests on children between the ages of 2-11 years old. Five of the seven studies reported some improvements in behavior of children with ASD. Weighted vests seemed to reduce stereotypic (repetitive) behaviors in some of the children. The vests increased attention or on-task time for some children. However, these were small studies and could not measure behaviors reliably. Therefore, the use of weighted vests in sensory integration therapy, in general, may not lead to consistent benefits for children with ASD.
