背景。作者的目的是评估6个月太极拳干预对减少老年人跌倒次数和跌倒风险的效果。这项随机对照试验包括256名年龄在70至92岁之间（平均年龄77.48岁，标准差4.95岁）的社区居民，他们从波特兰的一个患者数据库中招募。俄勒冈州。参与者被随机分为每周三次的太极组和为期6个月的拉伸对照组。主要结局指标是跌倒次数；次要结果测量包括功能平衡（伯格平衡量表、动态步态指数、功能延伸和单腿站立）、身体表现（50英尺快走、UpMGo）和对跌倒的恐惧，在基线、3个月、6个月（干预终止）和干预后6个月随访时进行评估。在6个月的干预结束时，与拉伸对照组相比，太极拳组明显减少了跌倒（n = 38 vs 73; p = 0.007），摔倒的比例更低（28% vs 46%; p = 0.01），伤害性跌倒（7% vs 18%; p = 0.03）。在调整基线协变量后，太极拳组的多次跌倒风险比拉伸组低55%（风险比，0.45；95%可信区间，0.30 ~ 0.70）。与拉伸组的参与者相比，太极拳组的参与者在所有功能平衡、身体表现和减少跌倒恐惧方面都有显著改善（p < 0.001）。在干预后6个月的随访中，太极拳组在这些措施中的干预效果保持不变。每周三次，为期6个月的太极项目对减少跌倒次数、跌倒风险和对跌倒的恐惧有效，并能改善70岁或以上缺乏运动的人的功能平衡和身体表现。
Background. The authors' objective was to evaluate the efficacy of a 6-month Tai Chi intervention for decreasing the number of falls and the risk for falling in older persons.Methods. This randomized controlled trial involved a sample of 256 physically inactive, community-dwelling adults aged 70 to 92 (mean age, 77.48 years; standard deviation, 4.95 years) who were recruited through a patient database in Portland. Oregon. Participants were randomized to participate in a three-times-per-week Tai Chi group or to a stretching control group for 6 months. The primary outcome measure was the number of falls; the secondary outcome measures included functional balance (Berg Balance Scale, Dynamic Gait Index, Functional Reach, and single-leg standing), physical performance (50-foot speed walk, UpMGo), and fear of falling, assessed at baseline, 3 months, 6 months (intervention termination), and at a 6-month postintervention follow-up.Results. At the end of the 6-month intervention, significantly fewer falls (n = 38 vs 73; p = .007), lower proportions of fallers (28% vs 46%; p = .01), and fewer injurious falls (7% vs 18%; p = .03) were observed in the Tai Chi group compared with the stretching control group. After adjusting for baseline covariates, the risk for multiple falls in the Tai Chi group was 55% lower than that of the stretching control group (risk ratio,.45; 95% confidence interval, 0.30 to 0.70). Compared with the stretching control participants, the Tai Chi participants showed significant improvements (p < .001) in all measures of functional balance, physical performance, and reduced fear of falling. Intervention gains in these measures were maintained at a 6-month postintervention follow-up in the Tai Chi group.Conclusions. A three-times-per-week, 6-month Tai Chi program is effective in decreasing the number of falls, the risk for falling, and the fear of falling, and it improves functional balance and physical performance in physically inactive persons aged 70 years or older.
