It was hypothesized that a combined Taoist Tai Chi (TTC) and a memory intervention program (MIP) would be superior to a MIP alone in improving everyday memory behaviors in individuals with amnestic mild cognitive impairment (aMCI). A secondary hypothesis was that TTC would improve cognition, self-reported health status, gait, and balance.
A total of 48 individuals were randomly assigned to take part in MIP + TTC or MIP alone. The TTC intervention consisted of twenty 90 min sessions. Outcome measures were given at baseline, and after 10 and 22 weeks.
Both groups significantly increased their memory strategy knowledge and use, ratings of physical health, processing speed, everyday memory, and visual attention. No preferential benefit was found for individuals in the MIP + TTC group on cognition, gait, or balance measures.
Contrary to expectations, TTC exercise did not specifically improve cognition or physical mobility. Explanations for null findings are explored.
研究假设,与单独的记忆干预计划(MIP)相比,将道家太极拳(TTC)与记忆干预计划相结合,能更好地改善遗忘型轻度认知障碍(aMCI)患者的日常记忆行为。第二个假设是,TTC能改善认知、自我报告的健康状况、步态和平衡能力。
共有48名个体被随机分配参与MIP+TTC组或单独的MIP组。TTC干预包括20节90分钟的课程。在基线时以及10周和22周后进行结果测量。
两组在记忆策略知识和运用、身体健康评分、处理速度、日常记忆及视觉注意力方面均显著提高。未发现MIP+TTC组个体在认知、步态或平衡测量方面有明显优势。
与预期相反,TTC锻炼并未特别改善认知或身体活动能力。对无显著结果的原因进行了探讨。
