Outline of Final Research Achievements

In order to clarify the characteristics and causes of poor motor skills in children with ADHD patients, motion analysis using a 3D motion analysis device and MR image analysis were performed . The motion analysis revealed the difference in the posture pattern during walking in chidlren with ADHD. It was also shown that the difficulties of motor skills observed in daily life are not peculiar to ADHD symptoms and may be influenced by the traits of autism spectrum disorder. Furthermore, although MRI analysis could not determine the brain region related to movement disorders in ADHD, correlation with the inferior parietal lobe and superior cerebellar peduncle was observed, so the possibility that is developmental delay of the brain region and nerve fiber fragility are involved.

Academic Significance and Societal Importance of the Research Achievements

ADHDを有する児童の多くは、学校や家での日常生活において運動面での苦手さから、親から怒られたり、周りと比べ自信をなくしたりするきっかけになっている。我々の結果より、ADHD児は運動機能そのものが低いことに加え、体の使い方や社会性の障害の影響を受けている可能性を示すことができた。また運動機能の低さは脳の発達遅延の影響も少なからず受けていることが推察され、ADHDを有する児童への運動や日常生活指導のあり方の一助となる根拠を示せたと考えている。
