Full-body musculoskeletal model with calibrated passive muscle forces

A full-body musculoskeletal model based on the model described by Rajagopal et al. (2016) with calibrated passive muscle force curves and improved hip abductor muscle paths. Changes to the Rajagopal model are described in our manuscript Uhlrich et al. (2022). The code for calibrating the forces is here: https://github.com/stanfordnmbl/PassiveMuscleForceCalibration.Passive muscle force curves were calibrated to match experimental data published by Silder et al. (2007). Hip abductor muscle paths were adapted to more closely align with MRI and experimental data.Rajagopal A, et al. "Full-Body Musculoskeletal Model for Muscle-Driven Simulation of Human Gait."

本数据集基于Rajagopal等人在2016年描述的全身体格肌肉模型，并对其进行了校准的被动肌肉力曲线以及优化的髋关节外展肌路径的改进。关于对Rajagopal模型的修改，已在Uhlrich等人的手稿（2022年）中进行详细描述。校准力的代码可在以下链接找到：https://github.com/stanfordnmbl/PassiveMuscleForceCalibration。被动肌肉力曲线的校准旨在与Silder等人（2007年）发表的实验数据进行匹配。髋关节外展肌路径的调整旨在更紧密地与MRI和实验数据相吻合。Rajagopal A等人的论文《全身体格肌肉模型：用于肌肉驱动的人步态模拟》发表于《IEEE生物医学工程汇刊》第63卷第10期（2016年）：2068-2079。（2016年）Uhlrich SD等人的论文《受肌肉骨骼模拟启发的肌肉协调再训练可减少膝关节接触力》发表于《科学报告》第12卷，文章编号9842。（2022年）https://doi.org/10.1038/s41598-022-13386-9Silder A等人的论文《下肢被动弹性关节力矩-角度关系的识别》发表于《生物力学杂志》第40卷第12期：2628-2635。（2007年）
