The effective of Vestibular stimulation on Improve motor skills in children educable mental retardation with developmental coordination disorder

Background and Aim: Children need to have appropriate sensory stimulation, sensory stimulation improve motor skills and competence for the children to school. Such as of these stimulations is vestibular stimulation. Many of the educable mentally disability child are the poor motor coordination and balance that some of these children, who are known as developmental coordination disorder (DCD). The aim of the present study was to evaluate the effectiveness of vestibular stimulation on improving motor skills in children educable mental retardation with developmental coordination disorder.‌‌‌Materials and Methods: This study is a quasi-experimental(pretest,posttest control group desingn). The statistical population of this study included all children with educable mentally disability in Elementary school in city of Isfahan. The sample included 30 children who were randomly selected from one dual-shift school. Then they were randomly assigned in to 2 equal groups: the experimental and control groups. The material used in this study was: Lincolen- Osertsky Motor test and Developmental Coordination Disorder List (DCD-Q,07; Wilson, 2007). Data were analyzed using Independent t-test and Mancova statistical method. Results: Statistically significant differences were observed in motor skills (Fine and gross) improvement in children with educable mental retardation using Vestibular stimulation (P<0.001). Conclusion: Vestibular stimulation therapy to have important positive effects on child’s ability to improve motor skills in subjects with mental retardation with DCD. Our results also showed that Vestibular stimulation therapy can significantly increase the motor skills perception development in educable mental retardation children.
