INTRODUCTION Individuals with Attention Deficit Hyperactive Disorder (ADHD) often have coexisting Developmental Coordination Disorder (DCD). The positive therapeutic effect of Methylphenidate (MPH) on ADHD symptoms is well documented, but its effects on motor coordination are less studied. We assessed the influence of MPH on motor performance in children with comorbid DCD and ADHD.
MATERIALS & METHODS In study 1 Participants were 18 children (13 boys, mean age 8.3 years) diagnosed with comorbid DCD and ADHD. In study 2 Participants were 30 children (24 boys) aged 5.10 to 12.7 years diagnosed with both DCD and ADHD. Conners' Parent Rating Scale was used to reaffirm ADHD diagnosis and the Developmental Coordination Disorder Questionnaire was used to diagnose DCD. The Movement Assessment Battery for Children-2(MABC-2) and the Online Continuous Performance Test (OCPT) were administrated to all participants twice, with and without MPH. The tests were administered on two separate days in a double-blind design.
RESULTS Motor performance and attention scores were significantly better with MPH than without it (p<0.001 for improvement in the MABC-2and p<0.006 for OCPT scores).
CONCLUSIONS The findings suggest that MPH improves both attention and motor coordination in children with coexisting DCD and ADHD. More research is needed to disentangle the causality of the improvement effect and whether improvement in motor coordination is directly affected by MPH or mediated by improvement in attention.
