Abstract
Objective
To evaluate Tai Chi´s effectiveness on balance and strength in the elderly across different intervention durations.
Methods
We conducted a comprehensive meta-analysis of 37 randomised controlled trials (RCTs) on balance and 22 RCTs on strength. The databases were searched in February 2023: AMED, CINAHL Plus, Medline, Web of Science, and Embase.
Results
Tai Chi significantly improved balance (SMD = 0.40; 95 % CI: 0.05 to 0.75; P = 0.03) and strength (SMD = 0.43; 95 % CI: 0.01 to 0.84; P = 0.04) in the elderly, especially in medium-term interventions (8–16 weeks). Long-term effects were not statistically significant, indicating variability in the sustained impact of Tai Chi.
Conclusions
Tai Chi is effective in improving balance and strength among the elderly, particularly with medium-term interventions. The variability in results across different study durations suggests a need for further research to optimise Tai Chi protocols and maximise its benefits in elderly care.
