Abstract

OBJECTIVE:

The aim of the study was to investigate motor performance in children with ADHD using a size-scaling handwriting task.

METHOD:

In all, 14 male children with ADHD and 14 typically developing (TD) children (age 7-15) wrote 10-mm and 40-mm cursive letter "l."

RESULTS:

Children with ADHD were unable to maintain their writing accurately at 40 mm, falling short by several millimeters; this was not evident in the TD children. Children with ADHD also had slightly faster and more fluent writing than TD children.

CONCLUSION:

It was concluded that children with ADHD have difficulties scaling handwriting movement in the larger 40-mm condition that may reflect poor planning and modulation of movement, despite having faster and more fluent movements.

KEYWORDS:

ADHD; comorbidity; motor control
