不同运动方式对骨性关节炎关节功能恢复的防治效果

The Effect of Different Movements on Recovering the Function of OA Joints

目的 :了解不同运动方式对骨性关节炎 (OA)关节功能改善的影响 ,以评价运动对OA防治效果。方法 :采用新西兰白兔左后膝长腿石膏管型伸直位固定的方法建立OA动物模型 ,依运动方式不同按随机分组原则进行分组 ,观察关节X线变化、活动度改善和关节周围韧带生物力学特性改变。结果 :X线表现示关节适宜运动有助于OA病情逆转 ,运动对恢复OA的关节活动度具有重要作用 ,可显著增强关节周围韧带抗张强度的恢复。结论 :运动可明显改善OA关节功能 ,延缓病情发展 。

To appraise the preventive and improvable effects of different movements on OA joints,animal models by fixing the left posterior knee joint in extention using plaster cast for 8 weeks in Newzealand rabbits were carried out. The rabbits were randomly divided into different groups, and the X-RAY、range of motion and ligament biomechanical features of the joint were observed.The results showed that proper movement improved the range of motion, restored tensile strength of the ligament around the OA joint.It is evident that movement improves the function of the OA joint and delays the OA exacerbation.The combination of active and passive movement is the best way to achieve good result.
