PROBLEM TO BE SOLVED: To provide an insole for the treatment of a lower limb disorder, capable of reliably fixing a sole board to a foot joint part so as to effectively prevent the rocking, effectively and conservatively treating lower limb disorder while keeping normally stable walking, and also effectively preventing damage due to the wear of the sole board, or the like.SOLUTION: The insole for the lower limb disorder treatment includes: a base board 1 formed in a substantially sole shape an elastic long belt 3 freely removably attached onto the base board 1 so as to be orthogonal to the board 1 and the wedge shape sole board 6 freely removably attached onto the base board 1 across the belt 3. The sole board 6 is set beneath the sole, and also both ends of the belt 3 are wound around the foot joint part 9 while being put on an instep in a cross state, for mounting.COPYRIGHT: (C)2009,JPO&INPIT【課題】本発明は、足底板を足関節部に確実に固定してその揺動を有効に防止せしめ、常に安定した歩行を保持せしめつつ下肢疾患の保存的治療を効果的に行うことが出来るのみならず、足底板の摩耗などに伴う損傷を有効に防止することが出来る、下肢疾患治療用足底装具を提供するものである。【解決手段】略足底形状とされた基板1と、該基板1上に直交して着脱自在に取付けられた弾性を有する長尺状ベルト3と、基板1上に該ベルト3を挟んで着脱自在に取付けられた楔形足底板6とよりなり、上記足底板6を足裏にセットせしめると共に、ベルト3両端を甲に交差状に当てがいつつ足関節部9に巻付けて装着せしめるべく構成されている。【選択図】図1
