Autism spectrum disorder is known as one of the most prevalent psychological disorders in children, which affects biomechanics of walking skills. The present study was conducted to compare the characteristics of the stance phases of walking in autistic children to their healthy peers. Forty children 7-12 years entered into two groups of children with autism and healthy. Timing of sub-phases, foot progression angle and total time of the stance phases was measured with foot scan device in walk way. The results indicated that in autistic children versus control group had more in forefoot contact and push-off phases, total time of the stance and foot progression angle and had lesser in the initial contact and foot flattening phases (P≤0/05). These findings suggested that autistic children had different strategies for body mass support at different stance phases.
