Abstract

While many studies of motor control in autism have focused on specific motor signs, there has been a lack of research examining the complete range of subtle neuromotor signs. This study compared performance on a neurologic examination standardized for children (PANESS, Physical and Neurological Exam for Subtle Signs, Denckla [1974 Developmental Medicine and Child Neurology, 16(6), 729–741]) between a group of 40 boys aged 6–17 with autism and average range IQs and a group of 55 typically developing boys. The Autism group was shown to have significant impairment on several measures of motor control compared to the Control group. Regression analyses revealed that a model including four PANESS variables offered a high level of discrimination in distinguishing boys with high-functioning autism from controls.
