Outline of Final Research Achievements |
We have demonstrated that the typical developmental process of the spatial and temporal control of anticipatory postural adjustments (APAs) varies with age. Our results suggest that all components of APAs, namely temporal and spatial control, and direction specificities, should be analyzed to capture the pathologic motor development in DCD. Furthermore, we have also demonstrated that mediolateral dynamic balance control during gait gradually improved with increasing age, and is associated with the development of contralateral limb coordination and trunk and pelvic twist coordination. The knowledge of the developmental process of the gait control during childhood is very important to advance effective balance assessment for abnormal development of DCD.

Academic Significance and Societal Importance of the Research Achievements |
本研究では,発達性協調運動障害(DCD)児の予測的姿勢調節(APAs)の特性を解明するための基盤データとなる定型発達児のAPAsの発達過程,および,歩行制御の発達過程について多くの知見を提供する事が出来た.特に,APAsのタイミングを調整する制御とAPAsの活動量を調整する制御の発達過程は異なるとの結果や,歩行時の四肢や体幹・骨盤の協調的な運動の発達が歩行の安定性に関与しているとの結果は,DCD児の姿勢・運動制御の特性を示す上での重要な知見だと考えられる.また,我々がこれまで示してきた分析手法,およびそれらの知見は,DCD児の評価及び治療のために世界的にも参考とされるデータとなると期待される.
