A Study on the Muscle Activity During Asymmetric Load Handling
허리의 비틀림 각도에 따른 근육 활동 분석
Abstract
Low back pain has been known as the most frequent musuculoskeletal disorders in modern industrial society and cost by low back pain is increasing mon and more. The asymmetric lifting has been identified as a major risk factor of low back pain. In this study, the muscle activity and muscle exertion level during asymmetric load handling (without trunk flexion) was estimated. The results of normalized MVC measurement were decreased about 16%, 24%, 34% respectively as the asymmetric angle was
