Randomized trial design
A total of 60 Tai Chi‐naïve healthy older adults, aged 50–79, were randomized to receive 6 months of Tai Chi training in addition to usual care or to usual health care alone (control group). Participants randomized to usual care were offered a 3‐month course of Tai Chi as a courtesy following the trial. Randomization was stratified by age (50–59 years, 60–69 years, and 70–79 years) and utilized a permuted‐blocks randomization scheme with randomly‐varying block sizes. All outcomes were assessed at baseline, 3 months, and 6 months; primary staff overseeing assessment and analysis of gait‐related outcomes were blinded to treatment assignment. Further details related to the design of the RCT component of this study are reported elsewhere (Wayne et al.,
