一个肩关节肌肉功能模型

Muscle function model of human shoulder

建立了一个人体肩关节三维肌肉功能模型,利用多刚体系统动力学原理,将肩关节节律导入模型之中;用欧拉角描述肩部各环节相对人体绝对坐标系的相对位置,得出不同位形下各骨标志点、肌肉附着点的全局坐标值及各肌肉肌拉力线的方向.本模型能更好得体现肩关节运动模式下的个体差异,为进一步的生物力学分析提供科学的理论依据.

In this paper, a muscle function model of human shoulder joint is developed. Base on the theory of multi-rigid-body system, the shoulder rhythm is implemented and the relationship of relative movement between the shoulder and the sternum are described by a set of Euler angles, absolute coordinates of each bone mark point and muscle attachment site are calculated, and the muscle lines-of-action are obtained accordingly. The model can better represent the individual difference of human shoulder kinematics, provided a academic base for further biomechanics investigation.
