Tai Chi Easy (TCE) is a low-impact, meditative movement practice that is feasible for breast cancer survivors, even in the face of post-treatment symptoms, and may even serve as a gateway into developing an active lifestyle and improving overall physical activity (PA). In the context of a randomized controlled trial testing effects of an 8-week TCE intervention on breast cancer survivors' symptoms, we examined the short- (8-week) and long-term (9-month) impact on total PA compared to an educational control group.
Participants were recruited from two hospital systems, local community organizations, and different media platforms. Eligible participants were predominant non-Hispanic White (82%), college educated (92%), and middle- to high-income (65%), and most commonly reported stage 1 (40%) or 2 breast cancer (38%). After baseline assessments, participants were randomized to the 8-week TCE intervention (N=51) or education control (N=53). Weekly intervention TCE classes were led by a trained instructor. Weekly educational control classes focused on a series of readings and group discussions. Total PA and steps were objectively measured via accelerometry, and the international physical activity questionnaire was used to measure self-reported total PA.
Multilevel mixed-effects linear regression models revealed no significant short- or long-term changes in objectively measured total PA or steps in either group; however, participants in the intervention reported short- and long-term changes in self-reported total PA.
TCE is an appropriate PA strategy for survivors that may lead to modest improvements in PA; however, more research is needed to examine the long-term impact on PA as well as other physical and psychological outcomes (i.e., flexibility, mobility, stress).
Low-impact, low-intensity activities like meditative movement practices are needed to assist survivors in overcoming post-treatment physical and psychological limitations to initiate a more active lifestyle.
简易太极拳（TCE）是一种低强度的冥想运动练习，即使面对治疗后的症状，乳腺癌幸存者也可行，甚至可能成为培养积极生活方式和改善总体身体活动（PA）的切入点。在一项随机对照试验中，测试了为期8周的TCE干预对乳腺癌幸存者症状的影响，我们将其与教育对照组相比，研究了对总身体活动的短期（8周）和长期（9个月）影响。
参与者从两个医院系统、当地社区组织和不同媒体平台招募。符合条件的参与者主要是非西班牙裔白人（82%），受过大学教育（92%），中高收入（65%），最常见的报告为1期（40%）或2期乳腺癌（38%）。在基线评估后，参与者被随机分为为期8周的TCE干预组（N = 51）或教育对照组（N = 53）。每周的TCE干预课程由一名训练有素的指导员带领。每周的教育对照课程侧重于一系列阅读材料和小组讨论。通过加速度计客观测量总身体活动和步数，并使用国际身体活动问卷来测量自我报告的总身体活动。
多水平混合效应线性回归模型显示，两组中客观测量的总身体活动或步数在短期或长期均无显著变化；然而，干预组的参与者报告了自我报告的总身体活动的短期和长期变化。
TCE是一种适合幸存者的身体活动策略，可能会使身体活动有适度改善；然而，需要更多研究来考察其对身体活动以及其他身体和心理结果（即灵活性、活动能力、压力）的长期影响。
需要低强度、低影响的活动，如冥想运动练习，以帮助幸存者克服治疗后的身体和心理限制，从而开始更积极的生活方式。
