Background Motor development allows infants to gain knowledge of the world but its vital role in social development is often ignored. Method A systematic search for papers investigating the relationship between motor and social skills was conducted, including research in typical development and in Developmental Coordination Disorder, Autism Spectrum Disorders and Specific Language Impairment. Results The search identified 43 studies, many of which highlighted a significant relationship between motor skills and the development of social cognition, language and social interactions. Conclusions This complex relationship requires more attention from researchers and practitioners, allowing the development of more tailored intervention techniques for those at risk of motor, social and language difficulties.
