Autism spectrum disorder (ASD) is a complex neurological development with onset in infancy or early childhood. Atypical sensory processing has been widely reported in ASD, and recent literature suggest that this abnormality extends across the life span, with consequent important implications in every-day life of autistic individuals and their families. Multisensory environments have been used in children with ASD precisely as a function of this particular difference in sensory processing and some studies have highlighted potential benefits. Therefore, the aim of our study is to verify feasibility and efficacy of an integrated treatment program with the multisensory room compared to as usual treatment in patients with ASD.
