运动是人类最重要的功能之一，为生存，进步和互动服务。步态需要肢体和肌肉的运动学和动力学协调、多感觉融合和鲁棒的控制机制。由脚与行走表面的相互作用产生的力刺激是人类步态的重要部分。虽然已经有许多研究试图破译步态的负载反馈机制，但需要开发一种能够推进研究并提供新功能的通用系统。在本文中，我们提出了一种新的系统，称为可变刚度跑步机（VST）的设计和表征。该装置能够通过真实的实时调节行走表面刚度来控制负载反馈刺激。VST的一些独特特征包括可用刚度的高范围、设备的分辨率和准确性以及在行走的站立阶段内调节刚度的能力。我们目前的实验与健康受试者，以证明我们的设备的概念和初步研究结果的影响，改变刚度步态运动学。所开发的系统构成了一个独特的有用的研究工具，它可以提高我们对步态的理解，并创造步态分析和康复研究的新途径。
Locomotion is one of the human's most important functions that serve survival, progress and interaction. Gait requires kinematic and dynamic coordination of the limbs and muscles, multi-sensory fusion and robust control mechanisms. The force stimulus generated by the interaction of the foot with the walking surface is a vital part of the human gait. Although there have been many studies trying to decipher the load feedback mechanisms of gait, there is a need for the development of a versatile system that can advance research and provide new functionality. In this paper, we present the design and characterization of a novel system, called Variable Stiffness Treadmill (VST). The device is capable of controlling load feedback stimulus by regulating the walking surface stiffness in real time. The high range of available stiffness, the resolution and accuracy of the device, as well as the ability to regulate stiffness within the stance phase of walking, are some of the unique characteristics of the VST. We present experiments with healthy subjects in order to prove the concept of our device and preliminary findings on the effect of altered stiffness on gait kinematics. The developed system constitutes a uniquely useful research tool, which can improve our understanding of gait and create new avenues of research on gait analysis and rehabilitation.
