Children who are dyscoordinated have difficulty with successfully performing activities of daily living at school and at home. When performing activities they exhibit timing impairments, notably inaccuracy and inconsistency. Additionally, an estimated 50% of children with DCD also exhibit cooccurring attention deficit hyperactivity disorder (ADHD). The purposes of this study were to determine if children who are dyscoordinated are able to improve accuracy and consistency in a timing task and attention and to examine if, following synchronized motor timing training (STT), they are able to maintain accuracy and consistency and selective attention even after an interval without practice. Thirteen participants ages 9-12 identified by their parents as having coordination difficulties consistent with those with Developmental Coordination Disorder were recruited.
