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.

这项生物医学工程研究计划的目标是量化健康成人上肢运动时的个体肌肉力量。这也将有助于解释肌肉共同收缩策略的时间演变，即关节两侧肌肉的相反动作，以及协同作用，即关节同侧肌肉的联合动作，为基础知识和未来在运动、机器人、康复、骨科、人体工程学和/或预防方面的创新应用。该计划包括3个具体目标：1。开发上肢的仿生和个性化动态模型，从而量化运动过程中的肌肉力量。2. 尽可能使用神经运动阻滞来验证它，即局部麻醉选定的肌肉。3. 用它来理解肌肉在屈伸、旋前和指向任务中的过度驱动策略。
