title: [Graphomotor functions in children with attention deficit hyperactivity disorder (ADHD)].
abstract: The present article is a review of studies concerning graphomotor functions (handwriting) in children with attention deficit hyperactivity disorder (ADHD) and the stimulant-induced (methylphenidate) alterations of both qualitative and quantitative aspects of handwriting. This review indicates an interaction between attentional functions and handwriting in ADHD children treated with methylphenidate. The comparison of writing movements of children on and off methylphenidate revealed that medication resulted in improved handwriting. However, kinematic analysis showed a deterioration in handwriting fluency on methylphenidate. A number of studies have demonstrated that children with ADHD display deficits regarding attentional functions. Treatment with methylphenidate has been shown to induce improvements of various attentional functions. Children with ADHD may use their increased attentional capacities to focus on skills (e.g. handwriting) that are independent of conscious control or may even be disturbed by attention.
