Effect of Visual Information on Postural Control in Children with Autism Spectrum Disorder

Visual information is crucial for postural control. Visual processing in children with autism spectrum disorder (ASD) was hypothesized to be less efficient and thus they would display a less stable standing posture than typically developing children. The present study compared the static standing responses and attentional demands of 15 children with ASD and 18 control participants in conditions of eyes open and eyes closed. The results showed that postural responses and attention invested in standing were similar between the participant groups in the two visual conditions. Both groups displayed a more stable posture when their eyes were open in comparison to eyes closed. The finding suggests that normal postural control development could occur in children with ASD.
