An effective way to avoid invading or injuring the subjects is to use the musculoskeletal model when studying the dynamic properties of muscles in vivo. So, we put forward a joint coordinate system-based method, which mainly focuses on the coordinate's transformation of corresponding muscle attachment points, respectively, in the model and the subject in order to reproduce the movement of the subject on the model. As muscle moment arm is usually used to evaluate the dynamic properties of muscles, the moment arms in elbow flexion for each of the major muscles crossing the elbow in 50 healthy subjects (25 males and 25 females), ranging in height from 1.50 to 1.80 m (mean 1.6542 m) are calculated and compared with the measured data obtained from anatomical studies reported in the literature. The trends of the value basically coincide with each other. So, this novel method can be valid.
在体内研究肌肉动态特性时，避免侵入或伤害受试者的一种有效方法是使用肌肉骨骼模型。因此，我们提出了一种基于关节坐标系的方法，该方法主要关注模型和受试者中相应肌肉附着点的坐标变换，以便在模型上重现受试者的运动。由于肌肉力臂通常用于评估肌肉的动态特性，我们计算了50名健康受试者（25名男性和25名女性）中跨越肘部的每块主要肌肉在肘部屈曲时的力臂，这些受试者身高在1.50至1.80米之间（平均1.6542米），并将其与文献中报道的解剖学研究获得的测量数据进行比较。这些值的趋势基本相互一致。因此，这种新方法可能是有效的。
