This study employed a 26-week cross-over, randomized control trial design in which each participant was assigned to one of two condition (i.e., 10 participants/cohort, 2 cohorts/condition) sequences at baseline: 1) the Tai Chi intervention condition then the usual care condition; or 2) usual care condition then intervention condition. The intervention condition requested participants participate in remote Tai Chi program for 60 minutes/session 2 times/week beyond their usual care. The usual care condition asked participants to maintain regular activities without Tai Chi and not to change their regular activity routine. Each condition lasted 12 weeks, with a 2-week washout separating treatments. The researchers monitored intervention fidelity via monthly follow-up phone calls.
