The aim of the study was to investigate motor performance in children with ADHD using a size-scaling handwriting task.
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."
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.
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.
本研究旨在通过一项大小缩放的书写任务来调查多动症儿童的运动表现。
总共14名患有多动症的男性儿童和14名发育正常（TD）的儿童（年龄7 - 15岁）书写10毫米和40毫米的连笔字母“l”。
患有多动症的儿童在书写40毫米的字母时无法准确保持，会短几毫米；而在发育正常的儿童中则不明显。患有多动症的儿童书写速度也比发育正常的儿童稍快且更流畅。
得出的结论是，患有多动症的儿童在40毫米的较大书写条件下难以缩放书写动作，这可能反映出动作规划和调节能力较差，尽管他们的动作更快且更流畅。
