Background: The aim of present study is to evaluate the Effectiveness of Sensory-motor stimulation on improving direction and movement localization in mental retarded children with developmental coordination disorder (DCD). Methods: The study design was tentative. Statistical population of this study included all educable mental retarded children in elementary school in Isfahan province. The sample included 30 children who randomly selected from one dual-shift school. Then, they were randomly assigned into 2 equal groups: the experimental and control groups. Materials that used in this study are: Lincolen– Osertsky Motor test and Developmental Coordination Disorder List. Data analyzed by ANCOVA statistical method. Results: Statistically, significant differences observed in improvement of direction and movement localization in educable mental retarded children that using Sensory-motor stimulation (P<0.001). Conclusion: Sensory-motor stimulation therapy has important positive effects on child’s ability to improve motor coordination in subjects with mental retardation with DCD. Results also show that Sensory-motor stimulation intervention can significantly increase the motor coordination in educable mental retarded children.
