Effects of Tai Chi on Balance Function in Community-Dwelling Older Adults: A Randomized Controlled Trial Examining the Predictive and Modifying Roles of Circadian Age, With Multi-Omics and Brain Function Assessments

This study investigates the effects of a 12-week Tai Chi intervention on balance function in community-dwelling older adults. Participants are randomly assigned to either a Tai Chi exercise group or a health education control group. The primary outcome is balance function measured by the Berg Balance Scale. Secondary outcomes include physical function, psychological well-being, cognitive function, and sleep quality. The study also explores the predictive and modifying roles of baseline circadian age on intervention outcomes.
