本文提供了在2009年澳大利亚足病学会议上发表的主题演讲的摘要。本文的目的是回顾最近的研究，采用动态尸体和侵入性运动学研究方法，以更好地了解步态过程中的足部和踝关节运动学。它不打算系统地涵盖与足部和踝关节运动学相关的所有文献（例如使用表面安装标记的研究）。由于本文是基于一个主题演讲，其重点是作者自己的经验和工作的主要，借鉴他人的工作，在适当的两种方法来访问和测量的问题，在脚的个别解剖结构的运动学已经采取，（i）静态和动态尸体模型，（ii）侵入性体内研究。尸体模型的优点是可以完全接近足部的所有组织，但尸体必须以复制足部在体内时表现的方式进行操作和加载。有创体内足部运动学研究的关键价值是足部运动学描述的有效性，但关键困难是如何将这些数据推广到更广泛的人群。通过这些技术，我们学到了很多东西。我们更好地理解了中足和前足关节对足部生物力学的重要贡献，以及踝关节和距下关节如何发挥几乎相似的作用。人与人之间在足部运动学上的差异是高的和正常的。这包括特定关节移动方式和关节组合移动方式的变化。脚继续展示其灵活性，使我们能够通过大量不同的运动学解决方案从A到B。我们不应该继续应用一个建立不充分的足型模型，其基础是使所有的脚都符合机械“理想”或“正常”足的标准，我们应该接受脚之间的差异，并将其视为开发患者特异性足功能临床模型的机会。
This paper provides a summary of a Keynote lecture delivered at the 2009 Australasian Podiatry Conference. The aim of the paper is to review recent research that has adopted dynamic cadaver and invasive kinematics research approaches to better understand foot and ankle kinematics during gait. It is not intended to systematically cover all literature related to foot and ankle kinematics (such as research using surface mounted markers). Since the paper is based on a keynote presentation its focuses on the authors own experiences and work in the main, drawing on the work of others where appropriate Two approaches to the problem of accessing and measuring the kinematics of individual anatomical structures in the foot have been taken, (i) static and dynamic cadaver models, and (ii) invasive in-vivo research. Cadaver models offer the advantage that there is complete access to all the tissues of the foot, but the cadaver must be manipulated and loaded in a manner which replicates how the foot would have performed when in-vivo. The key value of invasive in-vivo foot kinematics research is the validity of the description of foot kinematics, but the key difficulty is how generalisable this data is to the wider population. Through these techniques a great deal has been learnt. We better understand the valuable contribution mid and forefoot joints make to foot biomechanics, and how the ankle and subtalar joints can have almost comparable roles. Variation between people in foot kinematics is high and normal. This includes variation in how specific joints move and how combinations of joints move. The foot continues to demonstrate its flexibility in enabling us to get from A to B via a large number of different kinematic solutions. Rather than continue to apply a poorly founded model of foot type whose basis is to make all feet meet criteria for the mechanical 'ideal' or 'normal' foot, we should embrace variation between feet and identify it as an opportunity to develop patient-specific clinical models of foot function.
