Caused by cerebral damage, developmental coordination disorder (DCD) presents with extreme clumsiness when performing gross and fine motor actions. Difficulties in diagnostic consistency have been reported due to ambiguity in the definition of DCD. In the present study, we created a motor development checklist to enable assessment of potential DCD based on children's appearance during every day activities. Checklist validity was investigated through the joint application of a Developmental Voluntary Movement Test in children with intellectual disabilities aged 6 to 12 years in an elementary school special needs class. Findings showed a high correlation between the motor development checklist and developmental test evaluations of voluntary movement for 6 to 9 year olds and a low correlation for 10 to 12 year olds. Correlation was also observed between mental age (MA) and both the motor development checklist and the developmental test of voluntary movement; however, in children with suspected DCD, motor difficulties considerably exceeded those predicted by MA. These findings indicate a relationship between lack of sensory integration and difficulty with movements.
