Problem to be solved: to provide an apparatus for thoracolumbar orthosis, which can easily be mounted in a short period of time, and can easily maintain the extension position of the thoracolumbar spine, and can easily determine the upper and lower parts of the apparatus.Solution: the left and right shoulder arms 13 and 15, which extend over both shoulders, are connected to the upper part of the back plate 11, and the left and right chest pads 14 and 16 are disposed at the distal end of these arms 13 and 15, and the lower portion of the back plates 14 and 16 are wound on the lower part including the pelvis Waist belt 17 is connected.As a result, the fitting and removal of the fitting 10 including the temporary stop can be easily performed in a short time, and the extension position of the thoracolumbar can be maintained firmly, and the upper and lower discrimination of the apparatus 1 can be easily performed only by visually recognizing the mounting side of the left and right shoulder arms 13 and 15.Diagram【課題】仮止めを含めた装具の装着、取り外しが容易で、これらを短時間ででき、胸腰椎の伸展位を堅固に維持でき、また装具の上下の判別も簡単な胸腰椎用装具を提供する。【解決手段】背面プレート11の上部に、両肩を跨ぐ左,右肩用アーム13,15をそれぞれ連結し、これらのアーム13,15の先端部には左,右胸パッド14,16を配するとともに、この背面プレート14,16の下部には、骨盤を含む腰部に巻き付ける腰ベルト17を連結した。これにより、仮止めを含めた装具10の装着、取り外しが容易かつ短時間で可能であるとともに、胸腰椎の伸展位を堅固に維持でき、また装具1の上下の判別も、左,右肩用アーム13,15の取付側を視認するだけで簡単にできる。【選択図】図1
