目的探讨中心和家庭太极联合训练是否能提高老年遗忘性轻度认知障碍（a-MCI）患者的认知能力，降低生理性跌倒风险。设计随机对照试验。泰国清迈。参与者年龄在60岁及以上，符合彼得森多域a-MCI标准（N = 66）。干预：3周中心训练，12周家庭训练（每次50分钟，每周3次）。测量：认知测试，包括逻辑记忆（LM）延迟回忆、块设计、向前和向后数字广度、轨迹测试B-A部分（TMT B-A），以及使用生理特征评估（PPA）的跌倒风险指数。结果在试验结束时，在调整基线测试性能后，太极组在LM、Block Design和TMT B-A方面的表现明显优于对照组。太极拳组的PPA综合评分和PPA参数评分：膝关节伸展强度、反应时间、体位摆动和下肢本体感觉也明显更好。结论中心和家庭太极联合训练每周三次，持续15周，可显著改善老年多域a-MCI患者的认知功能，并适度降低生理性跌倒风险。太极拳可能对患有这种疾病的老年人特别有益。
ObjectivesTo examine whether combined center- and home-based Tai Chi training can improve cognitive ability and reduce physiological fall risk in older adults with amnestic mild cognitive impairment (a-MCI).DesignRandomized controlled trial.SettingChiang Mai, Thailand.ParticipantsAdults aged 60 and older who met Petersen's criteria for multiple-domain a-MCI (N = 66).InterventionThree weeks center-based and 12 weeks home-based Tai Chi (50 minutes per session, 3 times per week).MeasurementsCognitive tests, including Logical Memory (LM) delayed recall, Block Design, Digit Span forward and backward, and Trail-Making Test Part B-A (TMT B-A), and fall risk index using the Physiological Profile Assessment (PPA).ResultsAt the end of the trial, performance on LM, Block Design, and TMT B-A were significantly better for the Tai Chi group than the control group after adjusting for baseline test performance. The Tai Chi group also had significantly better composite PPA score and PPA parameter scores: knee extension strength, reaction time, postural sway, and lower limb proprioception.ConclusionCombined center- and home-based Tai Chi training three times per week for 15 weeks significantly improved cognitive function and moderately reduced physiological fall risk in older adults with multiple-domain a-MCI. Tai Chi may be particularly beneficial to older adults with this condition.
