Motor skill learning in children with and without Developmental Coordination Disorder

Objective: The question whether children with DCD have motor learning deficits is difficult to answer based on the current body of knowledge. The aim of this study was to examine the impact of practice on motor skill acquisition, retention and transfer in children with and without DCD using a variety of games in a virtual environment. Method: Performance on a criterion task (Wii ski game) and MABC-2 balance subscore was compared between children with DCD (n = 33) and TD children (n = 28) following 10 weeks of playing active video games. Repeated measures ANOVA was used to compare changes in the two groups. Results: The children with DCD demonstrated lower performance on the criterion task than the TD group (p = 0.031). A time by group interaction indicated that the difference in performance on the criterion task became larger over time (p = 0.039). No differences were found in retention between groups. Large improvement (Cohen d 1.11) was observed for the children with DCD on the MABC-2 balance subscore. Conclusion: Based on the criterion task results, typically developing children seem more proficient in learning new skills compared to children with DCD. More research is needed to confirm that children with DCD have a problem to transfer skills to other contexts.
