In this study, we aimed to determine whether a new measure of fine motor skills, the Pen Stroke Test (PST), can discriminate between children with and without attention-deficit/hyperactivity disorder (ADHD). Twelve children with ADHD and 12 controls age 8-11 were asked to produce handwriting strokes on a digitizer. The sigma-lognormal model derived from the Kinematic Theory of rapid human movements was used to analyze the strokes. Standard measurements of fine motor skills and handwriting were also obtained. Children with ADHD demonstrated poorer motor planning (t, D) and execution (nbLog) and greater variability in motor control (SNR/nbLog) than did controls. Parameters extracted from the PST were significantly correlated with performance on other motor and handwriting measures. This study provides preliminary evidence that the PST may be useful as a tool for rapidly detecting motor skill problems in the context of ADHD.
在本研究中，我们旨在确定一种新的精细运动技能测量方法——笔触测试（PST）能否区分患有和未患有注意力缺陷多动障碍（ADHD）的儿童。我们让12名患有ADHD的儿童和12名8至11岁的对照儿童在数字转换器上进行书写笔画。利用从快速人类运动运动学理论推导出来的西格玛对数正态模型对笔画进行分析。同时还获得了精细运动技能和书写的标准测量值。与对照组相比，患有ADHD的儿童表现出更差的运动规划（t，D）和执行能力（nbLog），以及更大的运动控制变异性（SNR/nbLog）。从PST中提取的参数与其他运动和书写测量的表现显著相关。本研究提供了初步证据，表明PST可能作为一种在ADHD背景下快速检测运动技能问题的工具。
