Intervention approaches and children with developmental coordination disorder.

Children with Developmental Coordination Disorder (DCD) have a marked impairment in the performance of functional motor skills required to succeed at school. Longitudinal studies show that without intervention children with DCD often do not improve with development and the poor motor behaviour appears to have a detrimental effect on other aspects of functioning such as school achievement, behaviour and self esteem. Outside of clinical situations, there are only a small number of controlled empirical investigations, and from this small number two types of approaches emerge. The first concentrates on processes underlying motor skills and purports to improve areas such as kinesthesis or sensory motor processes. The second concentrates on teaching functional tasks aiming to specifically intervene in the deficient areas. Evaluations of these approaches show that they both work, producing significant improvements over control groups but show no differences between other approaches. It is hypothesized that more general learning principles are producing the effect, such as accurate assessment and tailoring activities to meet the needs of any individual child. Further, it is suggested that work with non-specialists in the motor area, such as teachers and parents, is a way forward with all but the most severely affected children.
