Abstract

When we keep sitting for a long time, we end up with pain due to changes in the curvature in the waist. This study examined impacts from the wearing of a SPINE-GUARD(belt for the waist stabilization) on a cross-legged sit on variations of the Cobb's angle, lower back pain and trunk flexion angle. 15 men for the examination have watched movies or attended lectures while wearing a belt for 90 minutes per round for every five rounds for two weeks. The Cobb's angle showed a significant decrease from $48.36{\pm}14.57$ before wearing to $28.09{\pm}11.63$ after wearing (p<0.05). Pain decreased from $4.53{\pm}2.36$ before wearing to $2.733{\pm}2.153$ after wearing (p<0.05). The trunk flexion angle also showed a significant decrease from $82.33{\pm}20.30$ before wearing to $70.2{\pm}19.43$ after wearing (p<0.05). Given these findings, the wearing of a SPINE-GUARD seems to affect variations of the Cobb's angle and trunk flexion angle, and decrease of lower back pain.

앉은 자세를 장시간 유지하면 허리의 만곡에 변화가 오면서 통증이 발생하게 된다. 본 연구에서는 양반 앉은자세에서 SPINE-GUARD(허리 안정화 벨트) 착용이 허리뼈의 코브각과 허리통증 그리고 몸통 굽힘각도의 변화에 미치는 영향에 대해 알아보았다. 대상자 15명(남자)은 2주 동안 주 5회 매회 90분씩 벨트를 착용한 채로 영화를 감상하거나 강의를 들었다. 허리뼈의 코브각은 착용전 $48.36{\pm}14.57$에서 착용후 $28.09{\pm}11.63$로 유의한 감소를 보였다(p<0.05). 통증은 착용전 $4.53{\pm}2.36$이고, 착용후 $2.733{\pm}2.153$로 유의하게 감소하였다(p<0.05). 몸통의 굽힘각도 또한 착용전 $82.33{\pm}20.30$에서 착용 후 $70.2{\pm}19.43$로 유의한 감소를 보였다(p<0.05). 이것으로 보아 SPINE-GUARD의 착용은 허리뼈의 코브각 및 몸통굽힘각도의 변화 그리고 통증의 감소에 영향을 주는 것으로 사료된다.
