Currently, robust evidence is lacking to support one exercise type over another in the prevention of physical and cognitive decline and falls among older adults, primarily because of the lack of comparative trials of proven interventions. Therefore, a 12-month randomized, single-blind, comparative effectiveness trial is conducted, in which 142 older adults at high risk for falls are randomized (1:1) to receive an evidence-based Dalcroze Eurhythmics (DE) exercise program (once weekly, group-based) or an evidence-based multicomponent (MULTI) exercise program incorporating balance, functional, and strength training activities (twice weekly, group- and home-based), for 12 months. The primary outcome is gait variability under dual-task at 12 months. At 12 months, the DE group has significant improvements compared with MULTI group on gait under both dual-task (adjusted β for stride variability: -2.3, 95%CI, -3.1 to -1.4; p < 0.001) and single-task, and on a variety of secondary physical and cognitive/executive function outcomes. The adjusted hazard ratio for falls is 0.58 (95%CI, 0.37 to 0.93) for the DE group compared with MULTI group. In conclusion, DE exercise is more effective than MULTI exercise in improving physical and cognitive function and reducing falls in older adults. The mechanisms underlying DE exercise-induced benefits remain to be fully elucidated.
目前,缺乏有力证据支持某一种运动类型优于另一种运动类型可预防老年人身体和认知功能衰退及跌倒,主要原因是缺乏对已证实干预措施的比较试验。因此,开展了一项为期12个月的随机、单盲、比较有效性试验,将142名跌倒高风险老年人随机分组(1:1),一组接受循证的达克罗兹韵律操(DE)运动计划(每周一次,基于小组),另一组接受循证的多组分(MULTI)运动计划,该计划包含平衡、功能和力量训练活动(每周两次,基于小组和家庭),为期12个月。主要结局是12个月时双任务状态下的步态变异性。12个月时,与MULTI组相比,DE组在双任务(步幅变异性的调整β值:-2.3,95%CI,-3.1至-1.4;p<0.001)和单任务状态下的步态,以及各种次要身体和认知/执行功能结局方面均有显著改善。与MULTI组相比,DE组跌倒的调整风险比为0.58(95%CI,0.37至0.93)。总之,在改善老年人身体和认知功能以及减少跌倒方面,DE运动比MULTI运动更有效。DE运动带来益处的潜在机制仍有待充分阐明。
