The kinematics of each joint and the force-generating parameters for each muscle were derived from experimental data. The model estimates the muscle–tendon lengths and moment arms for each of the muscles over a wide range of postures. Given a pattern of muscle activations, the model also estimates muscle forces and joint moments. The moment arms and maximum moment generating capacity of each muscle group (e.g., elbow flexors) were compared to experimental data to assess the accuracy of the model. These comparisons showed that moment arms and joint moments estimated using the model captured important features of upper extremity geometry and mechanics. The model also revealed coupling between joints, such as increased passive finger flexion moment with wrist extension.<hr> </hr> <br/><br/>This project includes the following software/data packages: <br/> <ul> <li> <a href="https://simtk.org/frs?group_id=324#pack_494">Upper Extremity Model </a> : SIMM model of the human upper-extremity. </li> </ul>

关于模型：
本上肢模型包括代表肩部、肘部、前臂、腕部、拇指和食指的15个自由度，以及跨越这些关节的50个肌肉腔室。每个关节的运动学和每个肌肉的力生成参数均源自实验数据。模型估算肌肉-肌腱长度和各肌肉的力矩臂在广泛姿势范围内的变化。给定一组肌肉激活模式，模型还能估算肌肉力量和关节力矩。每个肌肉组的力矩臂和最大力矩生成能力（例如，肘部屈肌）与实验数据进行比较，以评估模型的准确性。这些比较表明，使用模型估算的力矩臂和关节力矩能够捕捉上肢几何和力学的重要特征。此外，模型还揭示了关节间的耦合关系，例如，随着腕部的伸展，被动手指屈曲力矩的增加。
