Effects of Baduanjin exercise on cognitive impairment in older adults: a systematic review and meta-analysis.

BACKGROUND

Cognitive impairment in older adults poses a growing burden on global healthcare systems, especially in resource-limited communities. Baduanjin exercise, a low-cost traditional Chinese mind-body exercise, demonstrates considerable potential for assisting older adults in managing cognitive impairment. However, there is no consensus regarding its efficacy. This meta-analysis aimed to assess the feasibility and effectiveness of Baduanjin exercise in ameliorating cognitive impairment in older adults.

METHODS

Randomized controlled trials (RCTs) published through January 30, 2025, were searched in PubMed, Web of Science, Cochrane Library, Embase, ClinicalTrials.gov, and Chinese databases (CSTJ, CNKI, Wanfang). Two reviewers independently conducted trial selection, assessed methodological quality using the Cochrane Risk of Bias tool, and extracted data in accordance with PRISMA guidelines. Seven RCTs involving 539 community-dwelling older adults met the inclusion criteria.

RESULTS

Baduanjin exercise significantly improved global cognitive function [mean difference (MD) = 2.15; 95% CI, 1.53 to 2.76; 0.00001], memory (standardized mean difference = 0.59; 95% CI, 0.38 to 0.80; 0.00001), executive function (SMD = 0.26; 95% CI, 0.07 to 0.44; 0.007), and physical health (MD = -0.86; 95% CI, -0.26 to -0.46; 0.00001). No included study reported adverse effects related to Baduanjin exercise.

CONCLUSION

These findings indicate that Baduanjin exercise can effectively improve cognitive impairment in older adults. Nevertheless, further rigorously designed RCTs are required to confirm these findings.
