Objective To improve the efficacy of exercise in community-dwelling older persons. Methods Based on the best evidence and barriers to exercise in older community residents, an evidence-based anti-fall group Otago exercise program was developed and implemented in 32 community dwelling older adults. The effect was evaluated after 5 months of the intervention. Results Twenty-nine participants completed the study. Their balance ability, falls efficacy, physical fitness level, falls risk, and satisfaction score and total score were significantly improved after the intervention compared with the baseline assessment (P<0.01 forall). Conclusion Evidence-based group Otago exercise can effectively enhance balance ability and physical fitness of the community elderly, resulting in reducing the risk of falls.
