The present invention relates to move both upper and lower extremities to the left, right, up, and down every direction at his back, also to adjust the distortion of the position and the spine of the shoulder by holding the position, attitude that can be acquired to improve and good attitude of stiff neck to provide the adjustment device. An attitude adjustment device 10, a cylindrical cavity of diameter 1.5~2.5cm using a polyvinyl chloride resin material on both sides of the rail-like in the cylinder between 1.5~5.5cm tie, ethylene - vertical 4.0~8.0cm wrapped in vinyl acetate copolymer resin material, and the horizontal 9.0~16.0cm, in the shape of the length 80~100cm. Both ends are connected with acrylonitrile-butadiene-styrene resin material 11 of the oval. By leave from the head to this attitude adjustment device to the pelvis, pressing the ends of the spine through the left and right of the erector spinae, the bending and twisting further shoulder of the position of the spine while maintaining the physiological curvature of the spine It can be adjusted.FIELD 2【課題】仰向けにて両上下肢を左右上下あらゆる方向に動かし、またその位置を保持することで肩の位置と背骨の歪みを調整し、肩こりの改善や良好な姿勢を獲得できる姿勢調整器具を提供する。【解決手段】姿勢調整器具10は、両側にポリ塩化ビニル樹脂素材を用いた直径1.5~2.5cmの空洞の円柱を円柱間1.5~5.5cmでレール状につなぎ、エチレン-酢酸ビニル共重合樹脂素材で包んだ縦4.0~8.0cm、横9.0~16.0cm、長さ80~100cmの形状をしている。両端は楕円形のアクリロ二トリル・ブタジエン・スチレン樹脂素材11にてつなげている。この姿勢調整器具に頭部から骨盤まで預けることで、左右の脊柱起立筋を介して背骨の両端を押圧し、背骨の生理的弯曲を保持したまま背骨の曲りや捻じれさらには肩の位置を調整できる。【選択図】図2
