Abstract
Frailty is a complex geriatric syndrome and serves as an indicator for functional degradation in older adults. Regular exercise intervention could reduce the level of frailty and improve general physical fitness. The aim of this study was to test the effects of the Vitality Acupunch (VA) exercise on the promotion of physical fitness and the improvement of frailty status among frail older adults in long-term care facilities. This study was a cluster-randomized controlled trial adopted a pretest-posttest design. Using convenience sampling, 81 frail adults older than 65years of age from 10 long-term care facilities participated in this study. The older adults were cluster-randomized by facility into an intervention group (5 long-term care facilities, n=40) and a control group (5 long-term care facilities, n=41). The intervention group engaged in the VA exercise 3 times a week, each lasting 40min, for 24weeks. The control group maintained regular activities of daily living. The outcome measures for physical fitness were assessed before study began (pretest), at the 12th week (posttest 1), and at the 24th week (posttest 2) in the study. After a 24-week intervention, the frail older adults who engaged in the VA exercise program showed significant improvements in handgrip strength, upper-limb muscle endurance, lung function, shoulder flexibility, forward flexion, shoulder joint flexion, and shoulder joint abduction (all p<0.05) but not in lower-limb muscle endurance (p=0.502) compared against their pretest data. The intervention group had significantly better physical fitness and positive changes in frailty status than the control group (all p<0.001), except for the lower-limb muscle endurance (p=0.557). Regular engagement in the VA exercise program for 24weeks significantly improved the physical fitness and frailty status of frail older adults in long-term care facilities.
