Outline of Final Research Achievements

Several studies show that children with attention deficit/hyperactivity disorder (ADHD) have gait abnormalities attributed to deficits of attention and executive function. To clarify the gait characteristics in children with ADHD using kinematic and kinetic parameters. By using a 3-D motion analysis system, we compared gait parameters in children with ADHD (n=19; mean age, 9.7 years) and children with typical development (TD) (n=21; mean age, 10.7 years). Regarding pelvis kinematics, the ADHD group exhibited a significantly higher anterior pelvic angle than the TD group. In the hip joint kinematics, peak extension and flex angle were significantly higher in the ADHD group than in the TD group. In multiple regressions, anterior pelvic angle also showed an association with severity of ADHD symptoms and cognitive abilities, but not with other psychiatric traits. Therefore, anterior pelvic angle might affect the gait characteristics in children with ADHD.
