运动疗法对社区中老年膝关节骨性关节炎患者下肢功能及肌力的影响

Effect of Exercise Therapy on Lower Limb Function and Muscle Strength of Elderly Patients with Knee Osteoarthritis in Community

目的:观察膝关节骨性关节炎中老年患者通过太极拳运动结合肌肉锻炼,其关节功能及肌力的变化。方法:在成都市武侯区簇锦社区中选取100例中老年膝骨关节炎患者,按照随机、对照法分为运动疗法干预组(简称:干预组)和对照组,每组50例。对照组给予健康宣教及口服塞来昔布胶囊,干预组在对照组基础上增加运动疗法,持续4周。分别于干预前、干预第2周、干预第4周及干预结束后第8周随访,比较两组间及组内干预前后WOMAC(Western Ontario and McMaster University Osteoarthritis Index)评分、股四头肌肌力的变化。结果:在干预第2、4周两组WOMAC评分均明显降低,干预组评分低于对照组(P<0.05),在干预结束后第8周随访时,两组WOMAC评分较治疗后均上升,但干预组依然低于对照组(P<0.05);在干预第2周时组间组内肌力均无明显变化,在第4周及干预后第8周随访时仅干预组较干预前好转,优于对照组(P<0.05)。结论:运动疗法明显改善社区中老年KOA患者的膝关节功能及股四头肌肌力,且具有良好的长期疗效。

Objective:To observe the changes in joint function and muscle strength of middle-aged and elderly patients with knee osteoarthritis through tai chi exercise combined with muscle exercise.Methods:In the community of Wuhou District of Chengdu,100 patients with middle-aged and elderly knee osteoarthritis were selected and divided into exercise therapy intervention group(referred to as intervention group)and control group according to random and control method,with 50 cases per group.The control group was provided with health education and oral celexib capsules,and the intervention group increased exercise therapy on the basis of the control group for 4 weeks.Follow-up was followed before intervention,week 2 of intervention,week 4 of intervention and week 8 after intervention,and the changes before and after two groups of WOMC scores,biceps strength and in-group intervention were compared.Results:①WOMAC score:The WOMAC scores of the two groups were significantly reduced at the 2nd and 4th weeks of intervention,but the reduction of the scores of the intervention group was significantly better than that of the control group(P<0.05).At the follow-up of 8 weeks after the intervention,the WOMAC scores of the two groups were compared with the treatment Both of them increased before,but the intervention group was still better than the control group when comparing between groups(P<0.05);②Quadriceps muscle strength:There was no significant change in muscle strength between the groups at the 2nd week of intervention,at 4th In the follow-up week and the 8th week after the intervention,only the intervention group improved compared with that before the intervention,and was significantly better than the control group(P<0.05).Conclusion:It clearly reflects that exercise therapy significantly improves the knee function and quadriceps muscle strength of middle-aged and elderly KOA patients in the community,and has good long-term effects.
