思春期側弯症腰椎カーブに足底挿板療法を用い，側弯の改善をみた1例

Improvement of Scoliosis by Arch Support Therapy to Treat Lumbar Curve in Adolescent Scoliosis. Case Report

　骨盤傾斜および扁平足を伴っている思春期側弯症に対し，足底挿板療法による治療を経験したので報告する．足底挿板療法の即時効果として内側縦アーチの左右差が減少し，足底挿板装着前Cobb角が29°であったが，足底挿板装着4週間後に14°，6カ月後には10°に改善した．また骨盤傾斜をみるpelvic coronal reference line(PCRL)は足底挿板装着前が6°であったが，足底挿板4週間後に4°と改善し，6カ月後には3°に改善した．足部から腰部への運動連鎖を考慮して治療を行うことで側弯症の改善が得られる可能性が示唆された．

　In this communication we report our experience with the use of arch support therapy in the treatment of an adolescent patient with scoliosis associated with pelvic inclination and flat feet.　The immediate effects of the arch support therapy in our patient were a decrease in the laterality of the medial longitudinal arch of the foot and a favorable change in the Cobb angle from 29° before wearing the arch support, to 14° at 4 weeks after starting to wear the arch support, and, finally, to 10° at 6 months.　The pelvic coronal reference line, which showed a pelvic inclination of 6° before wearing the arch support, had improved to 4° at 4 weeks after starting to wear the arch support, and to 3° at 6 months.　These findings suggested that scoliosis can be improved by treatment that takes into account the kinetic chain from the foot to the lumbar region.
