The equations of equilibrium are set up for the thoracic and lumbar spine and involve body weight, external load, muscle forces, and intervertebral reactions. These equations are solved using a linear programming technique that minimizes the total force in the system. The solution gives numeric values for the muscle forces and intervertebral reactions. The results for a subject in progressive forward flexion and in lateral bend are presented. Also examined are the effects of three different orthotic devices on the muscle forces of a patient with a scoliotic spine.
针对胸椎和腰椎建立了平衡方程，这些方程涉及体重、外部负荷、肌肉力量和椎间反应。使用线性规划技术求解这些方程，该技术可使系统中的总力最小化。该解决方案给出了肌肉力量和椎间反应的数值。给出了一名受试者在渐进性前屈和侧弯时的结果。还研究了三种不同的矫形器械对脊柱侧弯患者肌肉力量的影响。
