Outline of Final Research Achievements

In this study, we actively promoted the role of non-medical professionals and conducted (1) basic research on methods to assess posture and motor function related to locomotor disorders (evaluation of reliability and reproducibility) and (2) applied research to validate the assessment as a screening for locomotor disorders (cross-sectional and longitudinal surveys). In the evaluation of posture and movement, we targeted "mobility of the back (spinal column), basic movements such as crouching and flexibility of the lower limbs, and coordination of the upper and lower limbs," which are factors common to both children with inactivity and children with sports disorders. As a result, the relationship between sports disorders and posture and movement was extracted and evaluated in a simple and convenient manner The results of the study were as follows.

Academic Significance and Societal Importance of the Research Achievements

本研究は医学的及び工学的アプローチを組み合わせて課題の克服をめざし、医療従事者でなくても誰でも日常的に高品質なデータに基づいた早期発見が可能になり、予防医学の発展に寄与できる可能性を示した点で社会的意義が高い。特に、学校教育現場におけるスポーツ活動では、けがに関する専門的知識を有する者が少なく、痛みや違和感が発生してはじめて病院受診をすることが多かったが、リスク要因から発生を予見することで、ダメージを最小限に終えることの可能性を高めることに寄与できた。
