目的：准确描述注意缺陷多动障碍(ADHD)儿童在连续作业任务(CPT)中的运动异常。方法：采用结构式访谈(学龄儿童情感障碍和精神分裂症流行病学版)和DSM-IV标准进行诊断。用红外运动分析系统记录18例ADHD患儿(9.3+/-2.4岁)和11例正常对照(8.6+/-1.8岁)的运动模式，跟踪4个标志物的位置50次/秒，分辨率为0.04 mm。结果：ADHD男孩的头部移动频率是正常儿童的2.3倍(p<；.002)，移动距离是正常儿童的3.4倍(p<；.01)，覆盖范围是正常儿童的3.8倍(p<；.001)，并且有更线性和更简单的运动模式(p<；.00004)。他们的反应更慢，在CPT上有更大的变异性。头部运动的复杂性和反应潜伏期的变异性与教师评分显著相关。一个预先定义的运动和注意力组合区分了18名患者中的16名和11名对照组中的11名。结论：ADHD男孩相对不能安静地坐着是可以客观证实的，“坐立不安”似乎包括更频繁、更大幅度的全身运动。
Objective: To precisely describe movement abnormalities in seated children with attention-deficit hyperactivity disorder (ADHD) while they were engaged in a continuous performance task (CPT). Method: Diagnoses were made by using structured interviews (Schedule for Affective Disorders and Schizophrenia for School-Age Children-Epidemiologic Version) and DSM-IV criteria. Movement patterns of 18 boys with ADHD (9.3 +/- 2.4 years) and 11 normal controls (8.6 +/- 1.8 years) were recorded using an infrared motion analysis system that tracked the position of four markers 50 times per second to a resolution of 0.04 mm. Results: Boys with ADHD moved their head 2.3 times more often than normal children (p < .002), moved 3.4 times as far (p < .01), covered a 3.8-fold greater area (p < .001), and had a more linear and less complex movement pattern (p < .00004). They responded more slowly and with greater variability on the CPT. Complexity of head movement and variability in response latency significantly correlated with teacher ratings. A predefined composite of movement and attention discriminated 16 of 18 patients from 11 of 11 controls. Conclusions: The relative inability of boys with ADHD to sit still can be objectively verified, and ''fidgeting'' appears to consist of more frequent, larger amplitude, whole body movements.
