工作背景：手写技能，这是在学校，沟通和建立孩子的自尊心的成功至关重要，已被观察到是穷人在自闭症患者。关于自闭症儿童笔迹的信息很少，没有描述可能导致缺陷的具体特征。其结果是，具体方面的笔迹，自闭症患者表现出的困难仍然unknow.Methods：从儿童和没有自闭症谱系障碍（ASD）的笔迹样本的病例对照研究进行了明尼苏达手写评估。样本在5个类别中以单个字母为基础进行评分：易读性、形式、对齐、大小和间距。受试者也进行了测试，韦氏智力量表的儿童-IV和身体和神经系统检查微妙（电机）Signs.Results：我们发现，ASD儿童确实表现出整体较差的表现比年龄和智力匹配的控制在手写任务。更具体地说，患有ASD的儿童在形成字母方面表现出更差的质量，但在正确调整字母大小、对齐和间隔的能力方面没有表现出差异。在ASD组，运动技能显着预测的手写性能，而年龄，性别，智商，和visuospatial capabilities weren 't.Conclusions：我们解决了如何不同的元素的笔迹有助于在自闭症儿童中观察到的障碍。我们的研究结果表明，针对字母形成的训练，结合精细运动控制的一般训练，可能是改善自闭症儿童书写表现的最佳方向。神经病学（R）2009; 73：1532-1537
Background: Handwriting skills, which are crucial for success in school, communication, and building children's self-esteem, have been observed to be poor in individuals with autism. Little information exists on the handwriting of children with autism, without delineation of specific features that can contribute to impairments. As a result, the specific aspects of handwriting in which individuals with autism demonstrate difficulty remain unknown.Methods: A case-control study of handwriting samples from children with and without autism spectrum disorders (ASD) was performed using the Minnesota Handwriting Assessment. Samples were scored on an individual letter basis in 5 categories: legibility, form, alignment, size, and spacing. Subjects were also tested on the Wechsler Intelligence Scale for Children-IV and the Physical and Neurological Examination for Subtle ( Motor) Signs.Results: We found that children with ASD do indeed show overall worse performance on a handwriting task than do age- and intelligence-matched controls. More specifically, children with ASD show worse quality of forming letters but do not show differences in their ability to correctly size, align, and space their letters. Within the ASD group, motor skills were significantly predictive of handwriting performance, whereas age, gender, IQ, and visuospatial abilities were not.Conclusions: We addressed how different elements of handwriting contribute to impairments observed in children with autism. Our results suggest that training targeting letter formation, in combination with general training of fine motor control, may be the best direction for improving handwriting performance in children with autism.
