Studies using computerized dynamic posturogaphy reported abnormal postural balance in children with autism generally but, it was only clinically significant when somato sensory input was disrupted alone or in combination with other sensory challenges. Objective: To assess the postural control system in autistic children and trying to correlate their age and C.A.R.S score with their postural control. Methods: 1-Computerized Dynamic posturography was performed in 20 autistic children with (IQ<70) between ages 5 and 15 years and 15 age-matched healthy children.2- Childhood Autism Rating Scale (CARS) was performed in 20 autistic children with (IQ<70) between ages 5 and 15 years. Results: A significant difference was found between autisticandnormal children as regards their postural stability in all SOT conditions and also in VISandVEST ratios in sensory analysis results. There was statistically significant positive correlation between age in both the study and control groups and SOT results in all SOT conditions. As regards the degree of autism, this study comprised of 20 autistic children diagnosed by CARS and their CARS values ranged from 30to46 with a mean (31.8±5.94). In our study we found that there was statistically significant negative correlation between CARS score in the study group and SOT results in all conditions except in SOT1.Conclusions: There is significant affection of posture in the autistic children when compared to healthy children. Psychiatric rehabilitation of the study group has significantly improved their postural control
