股四头肌等长等张收缩锻炼在治疗膝骨关节炎中的作用

Quadriceps isometric isotonic contraction in the role of exercise in the treatment of knee osteoarthritis

目的观察通过股四头肌等长、等张收缩练习治疗膝骨性关节炎中的临床效果,并建立膝骨性关节炎运动处方。方法将60例膝关节骨性关节炎患者同期分为观察组30例(透明质酸钠关节腔注射+股四头肌等长等张收缩训练)、对照组30例(透明质酸钠关节腔注射),治疗前及治疗后、3个月、6个月、1年用Lysholms膝关节功能评分方法观察膝关节功能及临床疗效。结果两组治疗均可减轻疼痛,改善患膝功能,同治疗前相比差异有统计学意义(P<0.05);组间对比,观察组疗效优于对照组,差异有统计学意义(P<0.05)。结论坚持等长、等张收缩练习,能有效缓解关节疼痛,增强关节稳定性,改善关节功能,其远期效果优于玻璃酸钠。

Objective To observe clinical effects of knee osteoarthritis with the treatment of the isometric quadricepsfemoris contraction exercises, which aims at establishing the exercise prescription of knee osteoarthritis, and promotingits clinical application. Methods 60 patients with knee osteoarthritis were divided into two groups according to visitingsequence. There were 30 patients in the therapeutic group. The patients were treated with intra-articular injection ofsodium hyaluronate and isometric quadriceps femoris contraction exercises for treatment. There were 30 patients in thecontrol group. The patients were treated with conventional intra-articular injection of sodium hyaluronate. In our study,by measuring the diameter, daily function and HSS score to evaluate the clinical effect of treatment and make statisticalanalysis in pretreatment group and posttreatment groups at 3 and 6 months. Results Treatment of two groups reducedpain and improved knee function. Compared with pre-treatment difference was statistically significant （P 〈 0.05）. Comparison between groups, observation group was better than the control group, the difference was statisticallysignificant （P 〈 0.05）. Conclusion The isometric quadriceps femoris contraction exercises has obvious effect instrengthening the joint stability, improving joint function and alleviating the pain. Its long-term effect is better thanthat of control group.
