肌肉和关节力的数学预测需要肌肉起源和插入的定量知识。提出了一种基于标记三具尸体（六肢）的起源和插入的模型。从右到左的生物变异和/或犯错误有时是显著的，但它们很少导致力臂计算的变异大于20%，通常变异小于10%。正如预期的那样，小尸体和大尸体之间的肌肉起源和插入差异很大，使用单个样本或平均数据将导致肌肉力预测的大误差。提出了一种能有效减小误差的标度方案。发展直线肌肉模型的固有局限性包括：1)从右到左的生物变异和/或标记错误；2)当实际起始点或插入点的位置不能准确反映肌肉功能时，难以确定“有效”的起始点或插入点；3)不能用简单的标度方案来解释的主体间变异性。
The mathematical prediction of muscle and joint force requires a quantitative knowledge of muscle origins and insertions. A model is presented based upon marking the origins and insertions in three cadavers (six limbs). Right-to-left biological variations and/or making errors are sometimes significant, but they rarely result in moment arm calculation variations of greater than 20 percent and usually the variations are less than 10 percent. The muscle origin and insertion differences between small and large cadavers is great, as would be expected, and the use of single specimen or average data will result in large errors in muscle force predictions. A scaling scheme is presented which substantially reduces those errors. The inherent limitations of developing a straight line muscle model include: 1) right-to-left biological variations and/or marking errors; 2) difficulties in establishing “effective” origins or insertions when the locations of the actual origin or insertion do not accurately reflect muscle function; and 3) intersubject variability which cannot be accounted for by simple scaling schemes.
