The purpose of the study was to examine the effect of a sensory integration dance program on motor performance in children with developmental disabilities. Participants were 9 people with developmental disabilities (mean age; 11±2.0 years) by using convenient sampling. The study was designed as a single cohort pre and post-test comparative study. The dance program was performed 12 sessions (12 weeks, with a frequency of 1 times/week for 150 minutes per session). Motor performance was measured by Bruininks-Oseretasky Test of Motor Proficiency (BOT-2). Non-parametric tests, using the Wilcoxon singled-rank test for pairwise comparisons, were performed to evaluate pre- and post-intervention changes. As a result, manual coordination(p=.007), body coordination(p=.007), and total motor performance(p=.008) were significantly increased. Therefore, the sensory integrated dance art education program ‘Dancing artist’ was found to be a dance art education method that can improve the motor performance of children with developmental disabilities. These efforts are expected not only to develop a body that is a subject of sensory experience for children with developmental disabilities, but also to identify creative expression activities, artistic sensibility, achievement, free communication opportunities, and the possibility of growth as a disabled dance artist.
