Multibody dynamic modeling of the upper limb for the quantification of muscle force co-contraction and synergy strategies during motion

这个生物医学工程研究项目的目标是量化健康成年人上肢运动过程中的个体肌肉力量。这也将能够解释共同收缩的肌肉策略的时间演变，即关节两侧肌肉的相反动作，以及协同作用，即关节同一侧肌肉的联合动作，用于运动，机器人，康复，矫形外科，人体工程学和/或预防中的基础知识和未来创新应用。该计划包括三个具体目标：1。开发上肢的生物力学和个性化动态模型，从而能够量化运动过程中的肌肉力量。2.尽可能使用神经运动阻滞，即局部麻醉选定的肌肉。3.使用它来了解屈曲/伸展，旋前/旋后和指向任务期间的肌肉过度驱动策略。

The goal of this biomedical engineering research program is to quantify individual muscle forces during upper limb motion in healthy adults. This will also enable to explain the temporal evolution of muscle strategies of co-contraction, i.e. opposite actions of muscles on each side of a joint, and synergy, i.e. joint actions of muscles on the same side of a joint, for fundamental knowledge and future innovative applications in sports, robotics, rehabilitation, orthopedics, ergonomics and/or prevention. The program includes 3 specific objectives: 1. Develop a biofidelic and personalized dynamic model of the upper limb, enabling to quantify muscle forces during motion. 2. Validate it as far as possible using nerve motor blocs, i.e. locally anesthetizing selected muscles. 3. Use it to understand the muscle overactuation strategies during flexion/extension, pronation/supination, and pointing task.
