膝关节外收力矩（EKAM）与膝关节骨关节炎（OA）的存在、进展和严重程度密切相关。然而，目前缺乏方便实用的方法来实时估计和跟踪膝关节OA患者的EKAM，以进行临床评估和步态训练，特别是在步态实验室之外。开发了一种实时EKAM估计方法，并应用于跟踪和调查健康受试者和膝关节OA患者在踏上椭圆机期间的EKAM和其他膝关节力矩。在膝关节OA患者的踏步过程中，观察到EKAM和其他膝关节力矩的实质性变化。这是第一个研究开发和测试的EKAM的实时跟踪方法的可行性，对膝关节OA患者使用3-D逆动力学。该研究为我们提供了一种准确、实用的方法来实时评估膝关节OA相关的关键EKAM，有望帮助我们对膝关节OA患者进行诊断和评估，并为患者提供实时的EKAM反馈康复训练。
The external knee adduction moment (EKAM) is closely associated with the presence, progression, and severity of knee osteoarthritis (OA). However, there is a lack of convenient and practical method to estimate and track in real-time the EKAM of patients with knee OA for clinical evaluation and gait training, especially outside of gait laboratories. A real-time EKAM estimation method was developed and applied to track and investigate the EKAM and other knee moments during stepping on an elliptical trainer in both healthy subjects and a patient with knee OA. Substantial changes were observed in the EKAM and other knee moments during stepping in the patient with knee OA. This is the first study to develop and test feasibility of real-time tracking method of the EKAM on patients with knee OA using 3-D inverse dynamics. The study provides us an accurate and practical method to evaluate in real-time the critical EKAM associated with knee OA, which is expected to help us to diagnose and evaluate patients with knee OA and provide the patients with real-time EKAM feedback rehabilitation training.
