We have created a graphics-based software system that enables users to develop and analyze musculoskeletal models without programming. To define a model using this system one specifies the surfaces of the bones, the kinematics of the joints and the lines of action and force-generating parameters of the muscles. Once a model is defined, the function of each muscle can be analyzed by computing its length, moment arms, force and joint moments. The software has been implemented on a computer graphics workstation so that users can view the model from any perspective and graphically manipulate the joint kinematics and musculoskeletal geometry. Models can also be animated to visualize the results of motion analysis experiments. Since the software can be used to study models of many different musculoskeletal structures, it can enhance the productivity of investigators working on diverse problems in biomechanics.
我们创建了一个基于图形的软件系统，该系统能让用户无需编程即可开发和分析肌肉骨骼模型。要使用此系统定义一个模型，需指定骨骼的表面、关节的运动学以及肌肉的作用线和力生成参数。一旦定义了一个模型，就可以通过计算每块肌肉的长度、力臂、力和关节力矩来分析其功能。该软件已在计算机图形工作站上实现，以便用户能从任何角度查看模型，并以图形方式操纵关节运动学和肌肉骨骼几何结构。模型还可以制作动画，以可视化运动分析实验的结果。由于该软件可用于研究许多不同肌肉骨骼结构的模型，因此它可以提高从事生物力学各种问题研究的人员的工作效率。
