Few studies have evaluated the benefit of providing exercise to underprivileged older adults at risk for falls. Economically and educationally disadvantaged older adults with previous falls (mean age 79.06, SD = 4.55) were randomized to 4 mo of multimodal exercise provided as fully supervised center-based (FS, n = 45), minimally supervised home-based (MS, n = 42), or to nonexercise controls (C, n = 32). Comparing groups on the mean change in fall-relevant mobility task performance between baseline and 4 mo and compared with the change in C, both FS and MS had significantly greater reduction in timed up-and-go, F(2,73) = 5.82, p = .004, η2 p = .14, and increase in tandem-walk speed, F(2,73) = 7.71, p < .001 η2 p = .17. Change in performance did not statistically differ between FS and MS. In community-dwelling economically and educationally disadvantaged older adults with a history of falls, minimally supervised home-based and fully supervised center-based exercise programs may be equally effective in improving fall-relevant functional mobility.
很少有研究评估为有跌倒风险的贫困老年人提供锻炼的益处。将经济和教育处于劣势且有跌倒史的老年人(平均年龄79.06,标准差 = 4.55)随机分为三组:4个月的多模式锻炼组,其中完全监督的中心锻炼组(FS,n = 45)、最低限度监督的家庭锻炼组(MS,n = 42),以及非锻炼对照组(C,n = 32)。比较各组在基线和4个月时与跌倒相关的移动任务表现的平均变化,并与对照组的变化进行比较,结果显示FS组和MS组在计时起立行走测试中的减少幅度均显著更大,F(2,73) = 5.82,p = .004,η2 p = .14;在串联步行速度方面的增加也显著更大,F(2,73) = 7.71,p < .001,η2 p = .17。FS组和MS组在表现变化上无统计学差异。在有跌倒史的社区居住的经济和教育处于劣势的老年人中,最低限度监督的家庭锻炼计划和完全监督的中心锻炼计划在改善与跌倒相关的功能移动性方面可能同样有效。
