Abstract: [Abstract] This study investigated the nature of the hyperactivity component of attention deficithyperactivity disorder (ADHD) by comparing the number of movements made by boys with ADHD with a subjective evaluation of their hyperactive behavior. Fifteen boys with combined-type ADHD and 18 age-matched healthy boys wore an actigraph while attending elementary school, and the mean number of movements during formal in-seat classes and intervening free recess periods were compared between the two groups. In addition, the Japanese version of the ADHD Rating Scale-IV was dministered to each boy with ADHD by the teacher in charge in the morning at the end of the study period. No significant difference was seen between the twogroups in the mean number of movements during either formal in-seat classes or free recess periods ; however, the mean hyperactivity impulsivityscores on the teacher's ADHD rating scale exceeded the cutoff score of the 93rd percentile in both situations. Given these findings, an increased number of movements may not constitute a core component of hyperactivity in ADHD but rather an additional component in which increases occur only in specific situations. Additional studies are needed to investigate the intensity and variability of movements as well as the number of movements at school and home and compare them with a subjective evaluation of hyperactivity.
