Sensory integration therapy addressing speech and language in children diagnosed with Autism Spectrum Disorder (ASD): scope review

Abstract

Introduction: Autism Spectrum Disorder (ASD) involves challenges in sensory processing. These sensory difficulties can affect the development of speech and language and the Sensory Integration Therapy (SIT) is emerging as an approach to improve communication and social skills in children with ASD. Objective: To analyze, through a scoping review, the available evidence supporting the use of sensory integration therapy in speech and language interventions for individuals with ASD. Methods: A scoping review was conducted following the PRISMA-ScR extension criteria. Studies from various databases—including PubMed, Web of Science, ScienceDirect, Springer, and Academic Search Ultimate—were analyzed, covering articles in Spanish, English, and Portuguese, with no restrictions on publication year. Results: SIT has shown to be an effective approach for treating children with ASD, particularly in areas such as speech and language. Several studies reported improvements in various areas, including children’s pragmatic, semantic, morphosyntactic, and phonological skills. Conclusion: While initial results are promising, current evidence remains limited and lacks studies with consistent methodologies. Additionally, the scarcity of research in Latin America and the urgent need for collaboration between several professionals and family are highlighted to enhance therapeutic outcomes in the communicative development of children with ASD.
