As the lumbar region of the spine is particularly predisposed to musculoskeletal disorders, the aim of this article was to assess lumbar spine load on the basis of an accurate model of this part of the body. The model was developed with the finite element method and the energy criterion for optimising muscle work. Computer calculations confirmed that stresses and compression forces in intervertebral discs increased with an increase in the load force and that they were significantly larger in the bent forwards posture than in the erect posture. This result clearly shows that lifting light objects and the erect posture are important elements in minimising spine load.
由于脊柱的腰部区域特别容易出现肌肉骨骼疾病，因此本文旨在基于该身体部位的精确模型来评估腰椎的负荷。该模型是使用有限元方法和用于优化肌肉做功的能量标准开发的。计算机计算证实，椎间盘的应力和压缩力随负载力的增加而增加，并且在向前弯曲姿势下比在直立姿势下大得多。这一结果清楚地表明，提起轻物体和保持直立姿势是减轻脊柱负荷的重要因素。
