Effects of group motor skill intervention on five- to six-year-old children with developmental coordination disorder

The purpose of this study was to determine whether group motor skill intervention is an effective form of treatment when added to consultative services in 5- to 6-year-old children with developmental coordination disorder (DCD). An experimental group of DCD children (n = 17) was compared with a DCD control group without intervention (n = 20). The intervention was conducted once a week for 10 weeks. No significant differences between the groups in either Movement ABC motor test or the Movement ABC checklist were found before or after this intervention. When subgroups with different categories of motor difficulties were compared, significantly more children with borderline motor difficulties in the experimental group than in the control group had changed (improved) their category after intervention. It is concluded that children with definite motor difficulties do not benefit from this type of intervention. Future research should include comparison of well-defined subgroups of children with DCD.
