This article presents the motor skills and difficulties of children with attention deficit hyperactivity disorder (ADHD). More precisely, this paper refers to important research results in which the gross motor skills of ADHD boys (combined subtype) aged between 8 to 10 years old were investigated. The results show the necessity of motor evaluations in ADHD children that show a 50% prevalence of a developmental coordination disorder (DCD). The discussion suggests that these results can guide clinical applications.
