The gait1415+2 OpenSim Musculoskeletal Model of Osseointegrated Transfemoral Amp

This short communication presents the gait1415+2 musculoskeletal model, that has been developed in OpenSim to describe the lower-extremity of a human subject with transfemoral amputation wearing a generic lower-limb bone-anchored prosthesis. The model has fourteen degrees of freedom, governed by fifteen musculotendon units (placed at the contralateral and residual limbs) and two generic actuators (one placed at the knee joint and one at the ankle joint of the prosthetic leg). Even though the model is a simplified abstraction, it is capable of generating a human-like walking gait and, specifically, it is capable of reproducing both the kinematics and the dynamics of a person with transfemoral amputation wearing a bone-anchored prosthesis during normal level-ground walking. The model is released as support material to this short communication with the final goal of providing the scientific community with a tool for performing forward and inverse dynamics simulations, and for developing computationally-demanding control schemes based on artificial intelligence methods for lower-limb prostheses.Refer to this article: https://doi.org/10.1016/j.medengphy.2023.104091 <br/><br/>This project includes the following software/data packages: <br/> <ul> <li> <a href="https://simtk.org/frs?group_id=2786#pack_2420">Gait1415+2 Models </a> </li> </ul>

本篇简报介绍了在 OpenSim 平台开发的 gait1415+2 肌肉骨骼模型，该模型旨在描述穿戴通用下肢骨锚定假肢的截肢者的人体下肢。该模型具备十四个自由度，由十五个肌腱单元（位于对侧肢体和残肢）及两个通用驱动器（分别置于假肢膝关节和踝关节）所控制。尽管该模型为简化的抽象，但能够生成类似人类的行走步态，特别是能够再现截肢者穿戴骨锚定假肢在正常地面上行走时的运动学和动力学特性。该模型作为本篇简报的辅助材料发布，旨在为科学界提供一种进行正向和逆向动力学模拟的工具，并基于人工智能方法开发计算密集型控制方案，以用于下肢假肢。请参阅相关文章：https://doi.org/10.1016/j.medengphy.2023.104091。本项目包括以下软件/数据包：
