Resumen
Objective: to explore the specifility of impaired praxis and postural knowlegde to austin by examining three samples of children, includining those with austim spectrum disorder (ASD), attention-déficit hyperactivity disorder (ADHD), and typically developing (TD) children. Method: twenty-four children with ASD, 24 children with ADHD, and 24 TD children, ages 8 13, completed mesaures assesing basic motor control (the Physical and Neurological Exam for subtle Signs; PANESS), praxis (performance of skilled gestures to command, with imitation, and tool use) and the ability to regonize correct hand postures necesary to perform skilled gestures (the postural knowledge test; PKT). Results: Children with ASD performed significantly worse than TD children on all three assessments. In contrast, children with ADHD performed significantly worse than TD controls on PANESS. Conclusions: Whereas both children with ADHD and children with ASD show impairments in basic motor control, impairments in performance and recognition of skilled motor gestures, consistent with dyspraxia, appear, to be specific to development of skilled gestures and other goal directed behavior is specific to austim; whereas, impaired basic motor control may be a more generalized finding.
