Motor function in adults with Asperger's disorder: a comparative study

In the original description of Asperger's disorder (AD), clumsiness was an associated feature. Several studies of children have shown deficits in motor control, whereas research regarding adults is scarce. The aim of the present study was to compare motor function in adults with AD, with a normal comparison group. Gross and fine motor skills were examined by a standardized, norm referenced test developed for children, but also used in young adults, the Bruininks-Oseretsky Test of Motor Proficiency (BOTMP). In addition, a questionnaire regarding the participants' physical activity during leisure time was administered. We found that adults (age 21-35) with AD (N = 15) performed significantly worse than the normal comparison group (N = 29) in six of eight subtests in the BOTMP. Males with AD were less physically active than males in the comparison group. Among females, physical activity did not differ between the groups. There was a positive association between physical activity and gross motor function in the AD group. Participants with AD were encouraged by the assessments. Physical coaching may be an important future field for improving quality of life in adults with AD.
