title: Minimally supervised multimodal exercise to reduce falls risk in economically and educationally disadvantaged older adults.
abstract: 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.
