这项研究创建了牛津脚模型 (OFM) 的开源Python版本,以提高透明度. 结果显示openOFM v1.0准确地复制了ViconOFM,验证了其用于足部运动分析的用途.
科学领域:
- 生物力学 生物力学
- 整形外科 整形外科 整形外科
- 运动分析 运动分析
背景情况:
- 牛津足模型 (OFM) 对于足部运动分析至关重要.
- 之前的定制实现未能重现ViconOFM的结果,这表明缺乏透明度.
研究的目的:
- 创建一个ViconOFM (openOFM v1.0) 的开源Python复制.
- 根据OFM原始出版物开发第二个版本 (openOFM v1.1).
- 为了突出ViconOFM和原来的OFM描述之间的差异.
主要方法:
- 复制ViconOFM使用Python进行开源分发.
- 根据OFM原始文献开发了openOFM v1.1.
- 在健康和病态步行数据上使用规范化根平均平方误差 (NRMSE) 评估的实现.
主要成果:
- 在ViconOFM和openOFM v1.0之间,NRMSE的平均值为0.0012.
- 维康OFM的差异源于集成的平滑/空隙填充和细分定义变化.
- 微不足道的差异支持开放OFM的并发有效性.
结论:
- openOFM v1.0证明了与ViconOFM在健康和病态步行的同时有效性.
- openOFM v1.1 澄清了 ViconOFM 和原始 OFM 出版物之间的差异.
- 提供两个开放的OFM版本可以提高模型的可访问性,并促进进一步的研究.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
