[Problems] Knee, the supporter for use in joints such as elbows, and thereby maintain the joint is deformed by weakening or the like of muscle strength in a normal state to provide those with the effect of enhancing the motor functions themselves. A and also respectively provided with a compression attachable elastic band 3 in the vertical position across the joints of the mounting object, the inner position of the stretching band, by providing a muscular compression pad portion 2 corresponding to a plurality of muscle positions , to give a stimulus to the muscle groups sandwiching the joint site at the time of supporters wearing, stimulus same stimulus to adjacent muscle (muscle co-contraction action: Matthew and pressurize the part of a muscle that muscle and joint segments, the joint but by providing a) also acts on the muscles, better to work each muscle group.BACKGROUND 2.【課題】膝、肘等の関節に使用するサポーターにおいて、筋力の衰え等によって変形する関節を正常状態に維持させて運動機能自体を高める作用を備えたものを提供する。【解決手段】装着対象の関節を挟んだ上下位置でそれぞれ圧迫装着可能な伸縮バンド3を備えると共に、前記伸縮バンドの内側位置に、複数の筋肉位置と対応する筋肉圧迫用パッド部2を設けて、サポーター装着時に関節部位を挟んだ筋肉群に対して刺激を与え、同刺激が隣接筋肉にも刺激(筋共収縮作用:ある筋肉の一部を加圧するとその筋肉及び関節分節、関節を跨いだ筋肉にも作用する)を与えることによって、各筋群を良好に働かせる。【選択図】図2
