基于最优化的腰部肌肉力量预测模型被用于研究和人体工学实践,通常作为工作分析软件包的子程序。为了合理地选择一组满足力矩平衡的肌力,已经提出了各种优化准则,包括肌肉收缩强度的立方和,以及最小化脊柱压缩力和最大肌肉收缩强度的双线性规划方法。进行了一项实验室研究,以确定这两种模型公式是否对动态不对称提举的脊柱力产生显著不同的估计。尽管在两个模型的预测之间发现了统计学上的显著差异,但脊柱最大压缩力的差异仅为1.1%。
Optimization-based muscle force prediction models of the lumbar region are used in research and ergonomic practice, usually as a subroutine of a job analysis software package. Various optimization criteria have been put forward for use in rationally selecting a set of muscle forces to satisfy moment equilibrium, including the sum of cubed muscle contraction intensities and a double linear programming procedure for minimizing the spinal compression force and maximum muscle contraction intensity. A laboratory study was conducted to determine whether these two model formulations produce significantly different estimates of spinal forces for a dynamic asymmetric lift. Although statistically significant differences were found between the predictions of the two models, the difference in peak spinal compression force was only 1.1%.
