女性膝骨关节炎患者体质参数和肌肉功能状态的对照研究

目的：了解女性膝骨关节炎患者体质参数、肌肉功能的状况。方法：对参加试验的37例女性膝骨关节炎患者与37例正常女性，采用MES系统同步检测体重、体脂百分比、下肢肌肉分布系数、下肢最大肌力等数据，统计采用t检验。结果：患者组患侧肢体与对照肢体比较中，患肢的肌肉分布系数高于对照肢体（P=0．009）；在肢体的肌肉功能状态比较中，患肢的下肢最大肌力，下肢肌肉功能指数，单位体积肌肉肌力都显著弱于对照肢体（P〈0．05）。患者组的双侧下肢最大合力、肌肉功能指数、单位体积肌肉肌力都显著弱于对照组（P〈0．001）；结论：女性膝OA患者中，有效肌力要低于正常女性，而肌力降低主要是由肌肉效能的降低而非量的减少引起。

Control study for muscle force and component of body of female patients with knee osteoarthritis

Objective: To understand the information of female patients with knee osteoarthritis regarding muscle force,constitution parameter. Methods: Thirty-seven cases diagnosed as knee osteoarthritis and 37 controls were examined by MES. T-test was used to analysis two groups differences of muscle force,constitution parameter,et al. Results: Compared between affected limbs and controls limbs in patients revealed that the lower limb muscle distribution index of the affected limbs was higher than the control limbs (P<0.05), but comparison in functional status the lower limb muscle force,muscle functional index and muscle force of unit volume of the affected limbs were lower than the control limbs(P<0.05). Compared between patients group and control group the muscle force of both lower limbs,muscle functional index and muscle force of unit volume were lower than control group(P<0.001). Conclusion: The utility muscle force of lower limbs of female patients with knee osteoarthritis is weaker than healthy female. Muscle function disorder instead of muscle atrophy is the key cause of the weakness .
