Participants with attention-deficit/hyperactivity disorder (ADHD) are often impaired in visuomotor tasks. However, little is known about the contribution of modal impairment in motor function relative to central processing deficits or whether different processes underlie the impairment in ADHD combined (ADHD-C) versus ADHD inattentive (ADHD-I) subtype. The present study analyzes performance on the Visual Motor Integration Test relative to less effortful motor tests as well as on measures of energetics. Both ADHD groups showed evidence of impaired motor function on both visual-motor integration (VMI) and the less effortful motor tests. The ADHD-C group performed below the ADHD-I group on VMI, but their performance correlated highly with the measures of the energetic pools of arousal and effort. Different mechanisms may underlie impaired fine motor skills in ADHD. Central processing deficits contribute significantly to the deficit of ADHD-C but do not explain the motor impairment in ADHD-I.
参与者患有注意力缺陷/多动障碍（ADHD），通常在视动任务中受到损害。然而，对于运动功能的模态损伤相对于中枢处理缺陷的贡献，或者不同的过程是否为 ADHD 合并（ADHD-C）与 ADHD 注意力不集中（ADHD-I）亚型的损伤提供基础，知之甚少。本研究分析了视觉运动整合测试相对于低努力运动测试的表现，以及能量学测量。两个 ADHD 组在视觉运动整合（VMI）和低努力运动测试上都表现出运动功能受损的证据。ADHD-C 组在 VMI 上的表现低于 ADHD-I 组，但他们的表现与唤醒和努力的能量池的测量高度相关。不同的机制可能是 ADHD 精细运动技能受损的基础。中枢处理缺陷对 ADHD-C 的缺陷有显著贡献，但不能解释 ADHD-I 的运动障碍。
