Outline of Final Research Achievements

The purpose of this study was to obtain spatiotemporal parameters, arch structure, and plantar pressure distribution data during gait, and to attempt to evaluate changes in gait and quality of gait with growth based on the relationship between spatiotemporal parameters expressed as dimensionless quantities and plantar pressure distribution. The subjects were 944 male and female children and students. Plantar pressure distribution and movement during walking were measured, and walking behavior was evaluated in consideration of development. As a result, the plantar pressure distribution pattern with developmental progression showed changes in pressure at three sub-area in the hindfoot and forefoot regions. The velocity of the center of foot pressure did not affect the development of the medial longitudinal arch structure. The corrected spatiotemporal parameters during gait did not differ between ages, suggesting that the children had already acquired an adult gait at the age of 4 years.

Academic Significance and Societal Importance of the Research Achievements

歩行中の普遍的な足底圧分布パターンを確立することは，運動実践指導やトレーナーの所見だけではなく，ある一定の基準に沿った歩行評価のエビデンスが明らかになる．そのために歩行速度，時空間パラメーターを無次元量によって評価し，更に足底圧分布変数を合わせて分析することにより新たな評価方法が確立できる可能性がある．普遍的な足底圧分布パターンの定量化から平均値から個人のデータがどれくらい離れているのか，またどのようにすれば歩容が変えられるのか，具体的な目標値を設置することを可能にすると考えられ、本研究の結果は医療やリハビリテーションなど治療のための新たな歩行評価の可能性が期待される。
