摘　　要：目的:观察不同程度膝关节骨性关节炎患者的步态和下肢主要关节的运动学参数的变化,为膝关节骨性关节炎发病机制及康复治疗提供实验证据。方法:利用测力台和三维运动动作分析系统对照组(n=10)、轻患病组(n=13)、重患病组(n=9)膝关节骨性关节炎患者和进行步态分析和运动学参数测试。结果:两组患者步态周期中的支撑百分比显著大于对照组(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、踝关节支撑期最大跖屈角度、最大背屈角度和最大伸髋角度显著小于对照组(P<0.05)。结论:骨性关节炎患者明显的步态改变开始于足跟着地前,这不仅影响膝关节内外侧面承受的负荷,还可能导致现有病情的加重。患病组下肢主要关节参数明显异于对照组,提示存在一种代偿作用,但这种策略很可能只对轻患病组有效。Objective：The purpose of the present study is to explore the mechanism of knee osteoarthritis and supply experiment evidences to rehabilitation through observing the changes of gait and kinematics analysis of lower limb joints.Methods： By comparing gait and kinematics variables of control group（n=10）,less sever group（n=13） and sever group（n=9） using the force platform and motion analysis system.Results： The stance phase of the two osteoarthritis group is significantly higher than control group（P0.05）.The heel land phase maximal extensive and genuflex angle,peak ankle flex and dorsiflexion angle and peak hip extensive angle of the osteoarthritis groups is significantly smaller than control group respectively.Conclusions： the gait changes of osteoarthritis patients are before heel land phase,which do not only affect the load of internal and external side of knee joint,but also aggravate the symptoms.The results indicate that there is a compensation effect which lower limb joint of parameters are significantly different among those parameters,but the compensation effect may only have positive effect on the less sever osteoarthritis group.
