太极拳对老年膝骨性关节炎患者本体感觉及平衡功能的影响

The Effects of Tai Chi on Balance and Proprioception in Elderly with Knee Osteoarthritis:A Randomized Controlled Study

目的:探讨太极拳规律性锻炼对老年膝骨性关节炎患者本体感觉及平衡的影响。方法:将2014年8月至2015年10月在福建中医药大学附属康复医院骨伤康复科就诊的50例膝骨性关节炎患者随机分为太极拳组和对照组,两组各组25例。太极拳组进行规律性太极拳锻炼,对照组不进行额外健身运动。干预后比较两组的平衡及本体感觉指标。结果:太极拳组在闭眼平衡测试下,A-P方向轨迹长度及M-L方向轨迹长度明显小于对照组(p=0.0001,p=0.002),在睁眼平衡测试下,A-P方向轨迹长度优于对照组(p=0.044)。太极拳组平均错误率指标明显小于对照组(p=0.012)。经过12星期的太极拳训练,太极拳组闭眼A-P方向轨迹长度和项目执行时间明显优于治疗前(p=0.0001,p=0.001)。结论:规律性太极拳练习可改善老年膝骨性关节炎患者的下肢本体感觉及平衡能力。

Objective：The purpose of this study was to explore the effects of Tai chi exercise in older adults with knee osteoarthritis（KOA） in terms of balance and proprioeeption. Methods：A randomized single-blind control trial was conducted to test the effectiveness of Tai chi exercise in elderly with KOA. 50 elderly were recruited from Department of Orthopedic Rehabilitation in Fujian University of Traditional Chinese Medicine Subsidiary Rehabilitation Hospital between August 2014 and October 2015. Partici- pants were randomly assigned to a Tai chi group or a con- trol group by balanced randomization method. Tai chi group received regular Tai chi intervention 3 times a week for 12 weeks,and control group did not attend any additional exercise training during study period. Results：There were significant differences between the Tai chi group and control group in average trace error, anterior-posterior po- sition with open eyes, anterior-posterior position and medium-lateral position with closed eyes, p =0. 012,0. 044, 0. 0001,0. 002, respectively. Compared to baseline, there were significant changes in anterior-posterior position with closed eyes and test time execution, p =0. 0001,0. 001, separately. Conclusions：Regular Tai chi exercise had benefits for older population with KOA on improvement of proprioception of knee joint, balance stability compared with non-practicing group.
