【摘要】：目的观察不同角速度膝关节骨性关节炎患者膝屈伸肌群等速肌力变化,为膝关节周围肌群进行精准康复训练提供依据。方法采用随机分组方法将符合纳入标准的观察者30例分别纳入对照组及观察组,每组15例,选用IsoMed2000等速肌力测试训练系统,在30°/s、90°/s、180°/s角速度下以最大力量行膝关节屈伸运动,观察对比两组受试者在不同角速度情况下峰力矩(PT)及其总功(TW)数据指标。结果观察组两侧膝关节的屈伸肌群PT、TW在不同角速度下对比差异有统计学意义(P0.05)。对照组两侧膝关节的屈伸肌群PT、TW在不同角速度下对比差异无统计学意义(P0.05)。观察组右膝关节(患侧)屈伸肌群PT、TW在不同角速度下与对照组同侧膝关节相比差异有统计学意义(P0.05)。观察组左膝关节屈伸肌群PT、TW在不同角速度下与对照组同侧膝关节相比差异无统计学意义(P0.05)。观察组右膝关节(患侧)屈伸肌群PT在30°/s与90°/s、180°/s下两两对比差异有统计学意义(P0.05)。观察组右膝关节(患侧)屈伸肌群PT在90°/s与180°/s下对比差异无统计学意义(P0.05)。结论慢速等速肌力测试更能客观精准地检测出徒手肌力测试所不能分辨的肌力变化指标,利用等速肌力慢速测试对膝关节骨性关节炎患者膝关节运动相关肌群进行动态肌力测试是一项可行的方法,有助于膝关节肌肉运动能力康复计划的制订。
[Abstract]:Objective to observe the isokinetic muscle strength of knee flexion and extensor muscles in patients with knee osteoarthritis at different angular velocities, and to provide evidence for accurate rehabilitation training. Methods Thirty observers who met the inclusion criteria were randomly divided into control group (n = 15) and observation group (n = 15). IsoMed2000 isokinetic muscle strength test system was used at 30 掳/ s to 90 掳/ s. Knee joint flexion and extension motions were performed with maximum force at 180 掳/ s angular velocity. The peak torque (PT) and total work (TW) data of the two groups were observed and compared at different angular velocities. Results the PT,TW of flexion and extensor muscles of both knee joints in the observation group was significantly different at different angular velocities (P0.05). There was no significant difference in PT,TW of knee flexion and extensor muscles at different angular velocities in the control group (P0.05). The PT,TW of the right knee flexion and extensor muscle group in the observation group was significantly different from that in the control group at different angular velocities (P0.05). There was no significant difference in PT,TW of the left knee flexion and extensor muscles between the observation group and the control group at different angular velocities (P0.05). The PT of the right knee flexion and extensor muscle group in the observation group was significantly higher than that in the control group at 30 掳/ s and 90 掳/ s 180 掳/ s (P0.05). There was no significant difference in PT between 90 掳/ s and 180 掳/ s of right knee flexion and extensor muscle group in the observation group (P0.05). Conclusion slow isokinetic muscle strength test can more accurately and objectively detect the index of muscle strength change which can not be distinguished by the unarmed muscle strength test. It is a feasible method to use isokinetic slow muscle test to measure the dynamic muscle strength of knee joint associated with knee joint osteoarthritis, which is helpful to the formulation of rehabilitation plan of knee joint muscle motor ability.
