PROBLEM TO BE SOLVED: To conveniently and easily evaluate the dynamic characteristics of each foot.SOLUTION: The evaluation system includes: a load measuring means 6 capable of measuring the load of a foot when a subject is in a sitting position and the load of the foot when the subject is in a standing position an imaging means 2 for acquiring an image of the side portion of inside of the foot when the subject is in the sitting position and an image of the side portion of the inside of the foot when the subject is in the standing position and an arithmetic means 3 for computing an amount A of a vertical change of a navicular bone of the foot of the subject from the images of the side portion of the inside of the foot in sitting and standing positions, which are acquired by the imaging means 2, and an amount B of a change in load between the load when the subject is in the sitting and standing positions. The arithmetic means 3 computes a value of B/A as arch rigidity, and evaluates the degree of standing of each of the feet of the subject on the basis of the value of the arch rigidity.COPYRIGHT: (C)2013,JPO&INPIT【課題】簡易かつ容易に足の動的特性を評価することができるようにする。【解決手段】被測定者の座位における足の荷重と、被測定者の立位における足の荷重とを測定可能な荷重測定手段6と、被測定者の座位における足の内側の側部の画像と、被測定者の立位における足の内側の側部の画像とを取得する撮像手段2と、撮像手段2によって得られる座位及び立位における足の内側の側部の画像から被測定者の足の舟状骨鉛直変化量Aと、被測定者における座位の荷重と立位の荷重との荷重変化量Bとを演算する演算手段3と、を備え、さらに、演算手段3は、B/Aの値をアーチ剛性として演算しかつこのアーチ剛性の値に基づいて、被測定者の足の着地衝撃度合いを評価する。【選択図】図1
