摘　　要：目的 明确太极拳练习对功能性踝关节不稳(functional ankle instability, FAI)患者单脚支撑平衡控制能力影响,并进一步观察踝关节注意焦点的追加效应。方法 46名FAI患者随机分为踝关节焦点组(n=16),自由焦点组(n=15)和对照组(n=15)。踝关节焦点组和自由焦点组进行为期10周的太极拳练习,其中踝关节焦点组在练习时将注意力集中于踝关节,自由焦点组无注意焦点要求;对照组保持原有的生活方式,不进行专门的体育活动。使用三维测力台和Y平衡测试(Y balance test, YBT)对干预前后单脚站立的静态(睁眼和闭眼)、动态(即刻和持续)平衡控制能力进行测量。结果 踝关节焦点组和自由焦点组睁眼和闭眼单脚站立的足底压力中心(centre of pressure, COP)前后、左右晃动距离均显著减小,YBT 3个方向的伸触距离均显著提升;踝关节焦点组跳跃落地单脚支撑时左右方向稳定指数和总体稳定性指数显著减小。在运动干预后,踝关节焦点组和自由焦点组睁眼单脚站立的COP左右晃动距离小于对照组;踝关节焦点组闭眼单脚站立的COP左右晃动距离小于自由焦点组和对照组;踝关节焦点组YBT后内、后外侧方向的伸触距离大于自由焦点组和对照组。结论 太极拳练习可以全面提高FAI患者单脚支撑站立时静、动态平衡控制能力,而追加踝关节注意焦点的太极拳练习更加有效,尤其表现在闭眼静态和持续动态单脚支撑站立时左右方向的平衡控制。Objective To determine the effect of Tai Chi practice on balance control ability of the individuals with functional ankle instability(FAI)in single-leg stance(SLS),and further observe the augmented effect from attention focus on ankle.Methods A total of 46 individuals with FAI were randomly divided into ankle focus group,free focus group and control group.The ankle focus group and free focus group performed Tai Chi practice for 10 weeks;the ankle focus group focused their attention on the ankle joint,while the free focus group didn’t require attention focus;the control group maintained the origin lifestyle and didn’t engage in special physical activities.The three-dimensional force plate and Y balance test(YBT)were used to evaluate the static(with eyes open and closed)and dynamic(instant and continuous)balance ability of individuals with FAI.Results For ankle focus group and free focus group,the anterior-posterior(AP)and medial-lateral(ML)sway distances of center of pressure(COP)in SLS with eyes open and closed were significantly reduced,and the reach distance in YBT in three directions were increased.For the ankle focus group,the ML stability index and the dynamic postural stability index were significantly reduced during single-leg drop landing.The ankle focus group and free focus group had a significantly smaller ML COP sway distance than control group in SLS with eyes open;the ankle focus group had a significantly smaller ML COP sway distance than free focus group and control group in SLS with eyes closed;and the reach distance of ankle focus group in posterior-medial&posterior-lateral direction in YBT was longer than that of free focus group and control group.Conclusions Tai Chi practice can comprehensively improve static and dynamic balance control ability of the individuals with FAI in SLS,and ankle attention-focused Tai Chi practice is more effective,especially for the enhancement of their ML control ability in static state with eyes closed and in continuous dynamic SLS.
