| 摘要： |
| 目的：定量分析膝关节骨性关节炎（knee osteoarthritis,KOA）患者步态运动学参数的变化特点。方法：利用三维动作分析系统对轻病组、重病组膝关节骨性关节炎患者和对照组各30名进行运动学参数测试。结果：两组患者与对照组的时空参数相比，支撑期百分比参数较大（P<0.05）。关节角度方面，轻病组、重病组分别和对照组相比，最大伸髋角度明显减小（P<0.05）；足跟着地期伸膝角度、支撑期最大屈膝角度和支撑期最大伸膝角度等参数均明显减小（P<0.05）；踝关节支撑期最大跖屈角度和最大背屈角度较小（P<0.05），重病组与其他两组的差异较大（P<0.001）。结论：KOA患病组与对照组步态的运动学参数存在明显差异，说明患者为减少患病部位的负荷采取了相应的代偿策略。 |

| Abstract: |
| Objective:To make quantitative analysis of gait kinematics parameters in the knee osteoarthritis patients. Method:Thirty less severe KOA(L) patients,30 more severe KOA(M) patients and 30 control subjects were measured with VICON MX13 motion analysis system respectively. Result:In partly time-space parameters, KOA patients had more percent of stance phase than the control group（P<0.05）. In joint angle, compared with control subjects respectively, L group and M group had less peak hip extensive angle（P<0.05）; Less knee extensive angle during heel strike; Less peak knee flexion angle and less peak knee extensive angle during stance phase（P<0.05）; Less peak plantar flexion angle and less peak dorsiflexion angle of ankle joint during stance phase（P<0.05）. Conclusion:In KOA patients, there are notable differences in gait kinematics parameters analysis. |
