PURPOSE
To investigate effects of a short 8-form Tai Chi exercise on physical function, fear of falling, and depression in pre-frail elderly people living in senior communities.
METHODS
This 8-week randomized controlled trial was conducted in senior living communities with qualified pre-frail elderly subjects in a Tai Chi group (TCG, n= 32) and a control group (CG, n = 33). The TCG received TC intervention: three times/week, 60 min each; while the CG did usual care only. Assessments of the 30-s chair rise test (CRT), 4.5-m walking speed (WS), fear of falling (FOF), and Geriatric Depression Scale (GDS), were all applied at baseline, end of 4th week, and end of 8th week.
RESULTS
Between-group comparison at the 4th week showed significantly better outcomes in CRT (TCG: 14.56 ± 1.87; CG: 11.48 ± 2.83; P< .001) and WS (TCG: 4.28 ± 0.69; CG: 5.11 ± 1.16; P = .001) in the TCG than those in the CG, but not in FOF (TCG: 0.56 ± 0.56; CG: 0.79 ± 0.89; P = .228) and GDS (TCG: 7.91 ± 5.54; CG: 9.58 ± 6.85; P = .285). However, at the 8th week, significant differences (P< .001) were found in all four assessments: (1) CRT: TCG vs CG: 17.28 ± 2.00 vs 11.36± 2.94; (2) WS: TCG vs CG: 3.94 ± 0.59 vs 5.17 ± 1.22; (3) FOF: TCG vs CG: 0.16 ± 0.37 vs 1.00 ± 0.90; and (4) GDS: TCG vs CG: 3.84 ± 3.60 vs 9.97 ± 6.80, and the intervention effect of 8 weeks was better than at 4 weeks. For within-group comparison of the TCG, significant improvements were identified in CRT (P< .001), WS (P = .008), and FOF (P = .002); but not in GDS, P = .121 at the 4th week, and also in CRT (P< .001), WS (P< .001), FOF (P< .001), and GDS (P< .001) at the 8th week. On the other hand, there were no significant differences in the CG for pre- and post-comparison (CRT: P = .891; WS: P = .984; FOF: P = .636; GDS: P = .822).
CONCLUSION
This short-form TC exercise could improve physical function (the lower limbs' strength and gait speed), fear of falling, and depression.
目的
探讨短期 8 式太极拳锻炼对居住在老年社区的虚弱前期老年人的身体功能、跌倒恐惧和抑郁的影响。
方法
本 8 周随机对照试验在有合格虚弱前期老年人的老年社区进行，太极拳组（TCG，n=32）和对照组（CG，n=33）接受 TC 干预：每周 3 次，每次 60 分钟；而 CG 仅接受常规护理。在基线、第 4 周结束和第 8 周结束时，所有参与者都接受了 30 秒椅子起立测试（CRT）、4.5 米步行速度（WS）、跌倒恐惧（FOF）和老年抑郁量表（GDS）的评估。
结果
第 4 周时，TCG 在 CRT（TCG：14.56±1.87；CG：11.48±2.83；P<.001）和 WS（TCG：4.28±0.69；CG：5.11±1.16；P=.001）方面的结果明显优于 CG，但在 FOF（TCG：0.56±0.56；CG：0.79±0.89；P=.228）和 GDS（TCG：7.91±5.54；CG：9.58±6.85；P=.285）方面则无差异。然而，在第 8 周时，四项评估均存在显著差异（P<.001）：（1）CRT：TCG 与 CG 比较：17.28±2.00 与 11.36±2.94；（2）WS：TCG 与 CG 比较：3.94±0.59 与 5.17±1.22；（3）FOF：TCG 与 CG 比较：0.16±0.37 与 1.00±0.90；（4）GDS：TCG 与 CG 比较：3.84±3.60 与 9.97±6.80，且 8 周的干预效果优于 4 周。对于 TCG 的组内比较，CRT（P<.001）、WS（P=.008）和 FOF（P=.002）均有显著改善；但 GDS 无差异，P=.121 为第 4 周，CRT（P<.001）、WS（P<.001）、FOF（P<.001）和 GDS（P<.001）在第 8 周也有显著改善。另一方面，CG 在前后比较中无显著差异（CRT：P=.891；WS：P=.984；FOF：P=.636；GDS：P=.822）。
结论
这种短期的 TC 运动可以改善身体功能（下肢力量和步态速度）、跌倒恐惧和抑郁。
