Background: Balance is the basic component to reach a higher stage of development. Sixty-five percent of children with ASD experience an impairment motor. Motor impairment that is often found in children with ASD is a disturbance of balance. The given balance training usually focuses on vestibular, musculoskeletal and visual. Therefore, additional propioceptive stimulation is needed to improve the balance of children with ASD. Objective: The purpose of this study to determine balance training and propioceptive stimulation can improve the dynamic balance in children with ASD. Methods: This research was included in the Randomized Pre and Post Test Control Group Design. The sample in this research were 30 ASD children in Denpasar Autism Service Center (PLA) which divided into two groups. Fifteen children in the Control Group were not given treatment, 15 children in the Treatment Group were given balance training and propioceptive stimulation. The dynamic balance was measured by Four square step test. The time when doing a Four-Square step test was measured with a stopwatch. The longer the time it takes then the dynamic balance got worse. Result: The result of descriptive analysis of dynamic balance in Treatment Group before treatment was 15,33±2,87 second, and dynamic balance became better after treatment with mean of 11,47±2,45 second. The result of hypothesis test using Independent sample t-test in Control Group after treatment with Treatment Group after treatment got p = 0,002 (p <0,05) so Ha was accepted. Conclusion: Balance training and propioceptive stimulation improved the dynamic balance in children with ASD.
