Then the researcher-made test of fundamental movement is administered on them. Data are analyzed using multivariate analysis of variance. Results: The findings show a significant difference in the grasping, pulling& releasing movements between two groups. According to the findings, it can be concluded that the grasping, pulling& releasing movements of children with specific learning disorder are defective compared to normal children.
