PROBLEM TO BE SOLVED: To provide a compact stepper (a 3D stepper) for three-dimensional leg swinging exercise, having a high effect on softening of ankles, and being effective on the brain plasticity.SOLUTION: This three-dimensional stepper is configured to make the opening of the toes larger than that of the heels and, moreover, add a twist thereto based on the moving conditions of the legs of a human body by stepping, so that, when massaging the ankle which is hardened by stopping the exercise for a long period of time due to palsy, this stepper can provide an optimal driving without using other power. Further, the exercise is commanded using own intention and own hand so as to have a high spontaneity, so that this stepper has promising effects on the promotion of brain plasticity. Furthermore, this stepper has a moderately small size, can be combined with complex rehabilitation equipment that has been previously presented by the inventor so as to reduce an occupation area in use.COPYRIGHT: (C)2012,JPO&INPIT【課題】コンパクトで足首の軟化に効果が高く、脳の可塑性にも効果的な立体的足揺動運動用のステッパー(3Dステッパー)を実現する。【解決手段】本発明の3Dステッパーは、ステップを踏むことにより人体の足の動きの状況に基づき踵側より足先の開度を大きくしてある上、捻りも加えてあるので、麻痺などにより長期間動きを止めて硬くなった足首を揉み解すには、他の動力を使わない最適な駆動が実現できる。しかもこの運動は自分の意思および自分の手を用いて指示できるので自発性が強く、脳の可塑性促進に一層の効果的が期待できる。また装置の大きさは適度に小さく、更には本発明者の既出特許である複合リハビリ機器にも本発明を複合できるので、使用にあたっての占有面積を小さくできる。【選択図】図1
