An Investigation of Bilateral Coordination of Children with Specific Learning Disorder

The importance of perceptual skills development is in the lake or improvement in children’s motor function. The motor learning is the base of learning and higher mental processes created after the adequate development of motor and perceptual systems. This reason shows the importance of perpetual-motor impairment in learning deficits. According to the prevalence of learning disorder, this study was performed to evaluate the perceptual- motor skills in children with learning disorder.
This study was cross-sectional and case-control. The target group consisted of 38 children aged 7 to 9 years old studying in ordinary schools in city of Semnan who were diagnosed with learning disability as measured by the educational department. The control group consisted of 38 children without LD who were classmate with the LD group. For the evaluation of the bilateral coordination skills, the bilateral coordination subtest from the Bruininks-Oseretsky Test of Motor Proficiency was employed. The obtained data were analyzed by descriptive and inferential statistics and SPSS and Mann-withney software.
Statistical analysis showed that children with LD obtained lower scores in bilateral coordination subtest compared with normal children (P According to the results of this study, it seems that the overall performance of bilateral coordination in LD children is weaker than the children in the control group. Since the controllers of bilateral movement are the Motor cortex, cerebellum and basal ganglia and according to the role of basal ganglia and frontal lobe (that is closely in association with the motor cortex) in memory and learning, it seems that we can improve memory and learning ability with improving bilateral coordination movements .
