A dynamic model of the biomechanics of the index finger for flexion-extension and abduction-adduction motion is introduced. The model takes into account all the tendons in the finger and relates to their varying moment arms during motion. A new set of moment arm coefficients and elongation equations is derived based on experimental measurements of previous studies. Constraint equations using variable coefficients are introduced and an optimization approach used to obtain the tendon forces required for any given motion and external force. The model and optimization approach are tested with data from a rapid pinch experiment as well as a hypothetical disc rotation. Good correlation is obtained with respect to electromyographic data in the literature.
介绍了一种用于食指屈伸和外展-内收运动的生物力学动态模型。该模型考虑了手指中的所有肌腱，并涉及它们在运动过程中变化的力臂。基于先前研究的实验测量，推导了一组新的力臂系数和伸长方程。引入了使用可变系数的约束方程，并采用优化方法来获得任何给定运动和外力所需的肌腱力。该模型和优化方法通过快速捏取实验以及假设的椎间盘旋转数据进行了测试。与文献中的肌电图数据获得了良好的相关性。
