Feasibility of remotely delivered Tai Chi on older adults' 24-hour movement behaviors: A crossover randomized controlled trial
Abstract
BACKGROUND AND PURPOSE
The feasibility of remotely delivered Tai Chi (TC) interventions and their potential influence on 24-h movement behaviors (physical activity, sedentary time, and sleep) to promote health is limited. Thus, this study tested the feasibility of a remote TC program among community-dwelling older adults and examined its preliminary effects on 24-h movement behavior outcomes.
MATERIALS AND METHODS
A crossover randomized controlled trial enrolled 44 older adults assigned to either the AB sequence (12 weeks of remotely delivered TC followed by a 2-week washout and 12 weeks of usual care), or the BA sequence (the reverse order). Study feasibility was assessed by recruitment and retention rates, whereas intervention feasibility included intervention adherence, fidelity, and acceptability. The 24-h movement behaviors were tracked by a wearable sensor.
RESULTS
Forty-one participants (mean age = 70.8 ± 5.6; 78% women) completed the study and were included in the data analysis. Recruitment and retention rates were 76% and 93%, respectively. Results showed that 85% of participants completed ≥18 of 24 TC sessions, and 94% reported the acceptability of TC as "good" or "excellent". The linear mixed-effects models using period-level change scores showed no statistically significant treatment effects for steps, sleep time, sedentary time, lightly active time, or active time.
CONCLUSION
The findings demonstrate that a remotely delivered TC program is feasible, acceptable…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 44 participants or records.
