人体关节的数学建模需要有关人体测量参数的准确信息，如肌肉横截面积和肌肉力矩臂。本研究的目的是计算与脊柱屈伸有关的腹直肌(RA)和竖脊肌(ES)脊柱周围肌力矩臂的平均横截面积、平均体积和长度。这项研究的材料来自28名活着的受试者的档案计算机断层扫描。肌肉轮廓被数字化，瞬间手臂计算为前后躯干深度的百分比。RA平均横截面积为10.5cm2，ES平均横截面积为31.75cm2。RA和ES的平均体积分别为356.16 cm~3和843.46 cm~3。ES的肌力矩臂比为0.29，而男性和女性的RA分别为0.50和0.40。计算机断层扫描是一种允许精确计算内部人体测量参数的方法，这些参数将在数学建模中使用。《矫形外科运动物理杂志》1985；6(5)：278-280。
Mathematical modeling of human joints requires accurate information concerning anthropometric parameters such as muscle cross-sectional areas and muscle moment arms. The purpose of this study was to calculate the average crosssectional area, average volume, and length of the muscle moment arms about the spinal column for the rectus abdominis (RA) and the erector spinae (ES) for those portions of the muscles that are involved in spinal flexion and extension. Materials for this study came from archival computed tomography scans of 28 living subjects. The muscle outlines were digitized and the moment arms calculated as a percentage of anteroposterior trunk depth. The average cross-sectional area of the RA was 10.5 cm2, and 31.75 cm2 for the ES. The average volumes for the RA and ES were 356.16 cm3 and 843.46 cm3, respectively. The muscle moment arm ratio was 0.29 for the ES, while the males and females had ratios of 0.50 and 0.40, respectively, for the RA. Computed tomography scanning is a method that allows the accurate calculation of internal anthropometric parameters that will be of use in mathematical modeling.
