摘要：

背景：膝骨关节炎与生物力学因素密切相关。文献中应用现代步态分析方法对膝骨关节炎患者足底压力分布的研究报道较少。
目的：分析不同膝骨关节炎患者自然行走过程中的步态特征，试图探讨患者行走过程中不稳定的成因。
方法：采用footscan® SCSI 高频平板测试系统对22例中老年膝骨性关节炎患者进行了平地常速行走时步态特征的测试。
结果与结论：左膝疼、右膝疼和双膝疼患者的健侧和患侧的步态分期参数、足底各区域与地面的接触时间以及足的平衡参数存在着不同程度的差异。膝骨关节炎患者的步态参数反映了他们行走过程中存在着不稳定因素。

Abstract:

BACKGROUND: Knee osteoarthritis (KOA) is closely correlated with biomechanics. Modern gait analysis for sole pressure distribution of KOA patients is little.
OBJECTIVE: To analyze the gait characters of patients with different KOA during walking with normal speed and to investigate the cause for walking instability.
METHODS: To test the gait parameters of 22 patients in KOA when walking using the footscan® SCSI high frequency plate system.
RESULTS AND CONCLUSION: Differences were found in the parameters of the patients in left knee pain, right knee and double knees pain including the gait phase, the contacting time between every plantar area and ground and foot balance. The gait parameters of the KOA patients reflect the unstable factors in walking.
