In 2012, a randomized controlled trial, researchers Manh Hung Nguyen and Andreas Kruse have uncovered compelling evidence supporting the benefits of Tai chi for elderly individuals. Conducted in Vinh city, Vietnam, the study aimed to evaluate the effects of Tai chi on balance, sleep quality, and cognitive performance among community-dwelling seniors.

The trial involved 102 elderly participants who were randomly assigned to either a Tai chi group or a control group. Over six months, the Tai chi group engaged in regular Tai chi training, while the control group continued with their usual daily activities.

Researchers employed several standardized tools to measure outcomes: the Falls Efficacy Scale (FES) for balance, the Pittsburgh Sleep Quality Index (PSQI) for sleep quality, and the Trail Making Test (TMT) for cognitive performance.

The results were striking. Participants in the Tai chi group demonstrated significant improvements in cognitive performance, as evidenced by better scores in both parts of the TMT (TMT part A: F[1, 71] = 78.37, P < 0.001; TMT part B: F[1, 71] = 175.00, P < 0.001) compared to the control group. Furthermore, the Tai chi group reported substantial enhancements in balance (FES: F[1, 71] = 96.90, P < 0.001) and sleep quality (PSQI: F[1,71] = 43.69, P = 0.001).

The study concludes that Tai chi is a valuable practice for improving the balance, sleep quality, and cognitive abilities of elderly individuals. These findings suggest that integrating Tai chi into daily routines could offer significant health benefits for the aging population.
