Learning of Predictive Motor Control in Children with Developmental Coordination Disorder

The aim of this study was to examine learning of predictive motor control in children with developmental coordination disorder (DCD).The sampling design was purposive and from (aged 7-12 years) male students of Tabriz, 12 children with DCD by using DCDQ, PMOQ-T, and BOTMP tests, and 12 typically developing (TD) children (age and IQ matched) were selected. Participants were required to track a target moving along a circular path on a rotatory pursuit task by using game controllers. Predictive control was assessed by Variables which reflecting tracking success and behavior with the manual tracking. Results of repeated measure of analysis showed that there was a significant difference between DCD and TD children on measures of predictive control; total time on target (P=0.049), consecutive time on target (P=0.016), distance from the target (P=0.002) and velocity of the cursor (P=0.001). Collectively, probably DCD children had deficits in consolidation and learning of predictive motor control, they may be used feedback-based step-and-hold strategy, and an underlying deficit in the internal modeling was concluded in DCD children.
