| 目的探讨膝关节骨关节炎患者屈、伸膝肌练习效果的差异性。 方法18例膝关节骨关节炎患者（26个患膝）进行3～6周、每周3次的肌力练习，伸膝肌和屈膝肌练习的程度相同。练习前、后测定60°/s、120°/s和180°/s等速运动的峰力矩、单次最佳做功和力矩加速能。 结果屈膝肌参数（包括60°/s的单次最佳做功，120°/s的峰力矩、单次最佳做功和力矩加速能，180°/s的峰力矩和力矩加速能）均较伸膝肌参数有显著增加。 结论膝关节骨关节炎患者的伸膝肌和屈膝肌的练习效果不同，屈膝肌力改善程度好于伸膝肌。伸膝肌在功能性活动中起的作用更大，必须更注重伸膝肌的练习。 |

| Objective Muscle strengthening exercise can reduce the muscle inhibition of knee osteoarthritis (OA). The selective inhibition of knee extensors and flexors exists at spinal level so that doing extensors and flexors exercises equally should have unequal effects. The study tried to analyze whether the selection exists. MethodsEighteen knee OA patients (26 involved limbs)was involved in a muscle exercise procedure for 3-6 weeks (3 times per week), which exerted equal intensity on both knee extensors and flexors. The peak torque (PT), best work repetition (BWR) and torque acceleration energy (TAE) were tested at 60°/s, 120°/s and 180°/s before and after the exercise. ResultsFor knee flexors,the increase of parameters such as BWR at 60°/s, PT,BWR and TAE at 120°/s, PT and TAE at 180°/s were better than those for extensors significantly. ConclusionMuscle selection of the exercise effects was shown in knee OA patients that knee flexors strength increased more significantly than extensors strength. As the knee extensors play a more important role in the knee function than the flexors, much more attention should be paid on knee extensors exercise. |
