PROBLEM TO BE SOLVED: To provide an electro-stimulating device which achieves both of the fixation of a joint and the suppression of decrease of muscular strength.SOLUTION: The electro-stimulating device comprises a support 20 which is worn on parts of a human body including joint-bridging muscles which are muscles that bridge between joints. The support 20 is provided with a plurality of electrode sections 31-33 for applying electric current to joint bridging muscles. Each electrode section 31-33 is provided so as to correspond with the joint bridging muscles of the thigh 60 and the lower leg 70.COPYRIGHT: (C)2013,JPO&INPIT【課題】関節の固定と筋力の低下の抑制とを両立することのできる電気刺激装置を提供する。【解決手段】この電気刺激装置は、関節を跨ぐ筋肉である関節跨坐筋を含む人体の部位に装着するためのサポータ20を含む。サポータ20には関節跨坐筋に電流を流すための複数の電極部31~33が設けられている。各電極部31~33はそれぞれ、大腿60および下腿70の関節跨坐筋に対応する位置に設けられている。【選択図】図4
