Abstract:
A musculoskeletal (MSK) model is an important tool for analysing human motions, calculating joint torques during movement, enhancing sports activity, and developing exoskeletons and prostheses. To enable biomechanical investigation of human motion, this work presents an open-source lower body MSK model. The MSK model of the lower body consists of 7 body segments (pelvis, left/right thigh, left/right leg, and left/right foot). The model has 20 degrees of freedom (DoFs) and 28 muscle torque generators (MTGs), which are developed from experimental data. The model can be modified for different anthropometric measurements and subject body characteristics, including sex, age, body mass, height, physical activity, and skin temperature. The model is validated by simulating the torque within the range of motion (ROM) of isolated movements; all simulation findings exhibit a good level of agreement with the literature.
摘要:
肌肉骨骼(MSK)模型是分析人体运动的重要工具,计算运动过程中的关节扭矩,加强体育活动,开发外骨骼和假体。为了能够对人体运动进行生物力学研究,这项工作提出了一个开源的下体MSK模型。下半身的MSK模型由7个身体节段(骨盆,左/右大腿,左/右腿,和左/右脚)。该模型具有20个自由度(DoF)和28个肌肉扭矩发生器(MTG),这是根据实验数据开发的。该模型可以针对不同的人体测量和受试者身体特征进行修改,包括性,年龄,体重,高度,身体活动,和皮肤温度。通过模拟孤立运动的运动范围(ROM)内的扭矩来验证模型;所有模拟结果均与文献表现出良好的一致性。
