新型太极拳干预对老年女性膝骨关节炎患者下肢肌力和动态平衡影响

Effects of Innovative Tai Chi on the Lower-extremity Muscle Strength and Dynamic Balance of the Elderly Women with Knee Osteoarthritis

目的:验证6个月的新型太极拳康复方案干预是否可以改善老年女性膝关节炎患者的下肢肌力和动态平衡能力。方法:招募46名老年女性膝骨关节炎患者,随机分为太极组和对照组,进行为期6个月的实验干预。实验前后,通过等速肌力测试仪和动态平衡测试指标,测量所有受试者下肢肌力和动态平衡能力。结果:6个月前后,太极组下肢肌力无显著性差异(P>0.05),但动态稳定性显著性提高(P<0.05)。结论:新型太极拳康复干预可促进女性膝骨关节炎患者动态平衡稳定性,简易有效,易于推广。

Objective： To investigate whether a 6-month innovative Tai Chi （TC） exercise can affect the lower-extremity muscle strength and dynamic balance of the elderly women with knee osteoarthritis （OA）. Methods： A total of 46 elderly women with knee OA were recruited and were randomly divided into a TC group and a control group for an experiment of 6 months. Before and after the experiment, CON-Trex was used to evaluate the subjects＇ lower-extremity muscle strength and BBS, FRT and TUG were applied to evaluate the dynamic balance. Results： After 6-month TC exercise, the knee and ankle muscle strength showed no significant difference in TC group （p 〉 0.05）, but the group members＇ dynamic balance was significantly improved （p 〈 0.05）. Conclusion： The innovative Tai Chi can improve the dynamic balance of the elderly women with OA. It is easy to be promoted due to its simpleness and effectiveness.
