Abstract
본 연구는 산업 및 업무 현장의 환경에서의 요통 발생률을 최소화하고자 현재 지속적으로 연구되어지는 골반 자세와 요통 예방 치료를 위해 사용되어지는 허리벨트를 사용하여 요부의 척추기립근에 대한 근활성 정도를 알아보고자 하였고, 그 결과 벨트 미착용 시 근 활성이 유의하게 높게 나타났으며, 골반 전방경사시 더 높은 근활성을 나타냈다. 따라서 요부를 안전하고 요통의 위험요인 들로부터 예방하기에 적합한 요추 전만자세의 필요성을 알게 되었고, 허리벨트의 사용으로 인해 보다 올바른 물건 들기 자세를 교육할 수 있음을 알 수 있었다. The purpose of this study were to examine the effect of two different pelvic alignments and the back belt on electromyographic(EMG) activity of the erector spinae during lifting. The results were as follows: 1) EMG activity of erector spinae was greater when the pelvis was tilted anteriorly than when the pelvis was tilted posteriorly during lifting. 2) EMG activity of erector spinae was greater when the back belt than when without the back belt during lifting. These results suggest that the greater EMG activity of erector spinae with an anterior pelvic tilt position and with back belt during lifting may ensure optimal muscular support for the spine while handling loads.
