Autism spectrum disorder (ASD) is characterized by deficits in the areas of social interaction, social communication, and restricted and repetitive patterns of behavior. The literature shows that most of individuals with ASD, compared with typical development individuals, has deficits in motor skills. One of the motor skills that has been discussed is postural control. Therefore, it is necessary to investigate the relationship between postural control, communication, and socialization in children with ASD. The sample consisted of 46 children and adolescents, 34 (73.9%) of whom were male, aged between 6 and 17 years (M = 12.8; SD = 2.64). The force platform (Triaxial Digital P-6000) and the ABC, Vineland scales and the SON-R 6-40 intelligence test were used. In this way, the participants needed to, on the strength (Force) platform, remain still and in a straight posture, barefoot with their feet apart in the heir feet hipwidth apart, and with arms relaxed along the body for 30 seconds. In the first part of the procedure, it was asked or the participants remained with their eyes open, looking straight ahead at a fixed point 1m in front of them. Then the procedure was repeated with the participant’s eyes closed. For analysis, the sample was divided int 3 groups. The data shows that there was no significant correlation between language development, sex, or age, as well as variable of the COP. The maintenance of postural control seems to suffer more impact when the vision is altered, presenting a greater displacement in both the M/L and the A/P planes, regardless of whether it is on firm ground or in foam.
