| Outline of Final Research Achievements |
In order to measure in real time the ground reaction force, the center of plantar pressure and the arch of sole, we have developed an inexpensive and simple gait measurement insole system by combining two or more commercially available inexpensive thin-film force sensors. Several mechanical properties, such as compressive load, shear force and bending stress, were made to evaluate the performance of commercially available inexpensive thin-film force sensors and a new designed triaxial shear force sensor. In addition, the estimating results of ground reaction force waveform and trajectory of the center of plantar pressure were verified experimentally over different footwear and walking pace on a group of subjects. It will be expected that the research results have been contributed to sports instruction and walking rehabilitation in the field.

| Academic Significance and Societal Importance of the Research Achievements |
研究成果は，日常的に「歩き方」や「走り方」を把握することは勿論のこと，スポーツ指導の現場での利用，歩行リハビリテーションでの下肢機能の評価，術前・術後の比較分析を行う場面で貢献する。さらに，本研究で開発した歩行計測システムの有用性を，方向転換，段差歩行など日常動作で起こり得る突発的な動作や，高齢者や障害者のような下肢疾患者で確認できれば，高齢者の躓き・転倒メカニズムの解明や高齢者のための生活空間や住宅設計にも貢献すると考えられる。
