疑似发育障碍的儿童通常有书写困难，并表现出头部和上肢运动控制的问题，但尚未进行详细检查。本研究旨在探讨疑似发展障碍及书写困难儿童的运动控制特点。19右撇子男性谁是在资源室接受支持的手写困难（SDD组）进行了比较，17右撇子年龄匹配的男性控制。两组人都完成了两项手写任务。主要措施是颠簸和关节角度的变化，这是由一个三维运动分析系统测量。与对照组相比，SDD组的头部、前臂和手部的挺举平均值显著更高，两项手写任务中颈部屈曲关节角度的变化显著更大。疑似发育障碍和书写困难的儿童前臂运动不太平稳，头部运动更固定。
Children with suspected developmental disabilities often have handwriting difficulties and show problems with motor control of the head and upper limbs, but it has not been examined in detail. The purpose of this study was to examine the characteristics of motor control in children with suspected developmental disabilities and writing difficulties. Nineteen right-handed males who were receiving support in the resource room for handwriting difficulties (SDD group) were compared with 17 right-handed age-matched male controls. Both groups completed two handwriting tasks. The main measures were jerk and changes in joint angle, which were measured by a 3D motion analysis system. The SDD group had significantly higher mean values of jerk in the head, forearms, and hands and significantly greater changes in the joint angle of neck flexion in both handwriting tasks compared to the control group. Children with suspected developmental disabilities and handwriting difficulties had less smooth forearm movements and greater fixed head movements.
