In order to test the hypothesis that attention deficit hyperactivity disorder (ADHD) is related to deficits in somatosensory processing, 49 ADHD male children and 49 matched controls were tested on a wide range of tactile tasks, and somatosensory evoked potentials (SEP) were also recorded. In addition, parents' and teachers' ratings on the children's typical responses to tactile stimuli were obtained. The results show that the ADHD children were less skilled on suprathreshold, but not on threshold tasks than were the controls. Further, a larger percentage of ADHD children were 'tactile defensive'. Finally, the ADHD children showed larger-than-normal amplitudes of late, but not early components of the SEP. These data suggest that some aspects of somatosensory processing by ADHD children are deficient.
为了检验注意力缺陷多动障碍（ADHD）与体感加工缺陷有关这一假设，对49名患有ADHD的男童和49名匹配的对照组儿童进行了一系列触觉任务测试，并记录了体感诱发电位（SEP）。此外，还获得了家长和教师对儿童对触觉刺激的典型反应的评分。结果显示，与对照组相比，ADHD儿童在阈上任务中的技能较差，但在阈限任务中并非如此。此外，有更大比例的ADHD儿童表现为“触觉防御”。最后，ADHD儿童SEP的晚期成分而非早期成分的波幅大于正常。这些数据表明，ADHD儿童的体感加工在某些方面存在缺陷。
