Objectives:
There exists a deficiency in a distinct understanding of the intervention effects of Traditional Chinese Medicine (TCM) exercise therapies (Tai Chi, Yi Jin Jing, Ba Duan Jin, Liu Zi Jue, Qigong, Wu Qin Xi etc.) on cognitive function and its moderating variables in the elderly. This study aims to systematically evaluate the effects of TCM exercise therapies on the cognitive function of the elderly and further propose the best exercise intervention programme to delay the cognitive decline of the elderly.
Methods:
PubMed, EBSCO host, Web of Science, EMbase, China National Knowledge Infrastructure and Wan Fang databases were searched for the effects of TCM exercise therapies on the cognitive function in older adults until July 2022. A meta-analysis of the included literature was performed using Stata 12.0 software, with a subgroup analysis of seven moderating variables: subject type, intervention content, intervention duration, intervention frequency, intervention period, study type and sample size. A random effects model was used to combine the overall effect sizes and to test for heterogeneity and publication bias across studies.
Results:
A total of 20 publications with 1975 subjects were included. The TCM exercise therapies delayed cognitive decline in older adults (d = 0.83; 95 % CI [0.62-1.04]; P < 0.001). Subgroup analysis found that intervention content, intervention duration, intervention frequency, and intervention period were significant moderating variables influencing the effectiveness of the intervention. Among them, the Ba Duan Jin intervention (d = 0.85; 95 % CI [0.65-1.06]; P < 0.001), the duration of each exercise session of 60 min or more (d = 0.86; 95 % CI [0.71-1.00]; P < 0.001), the frequency of exercise of more than 5 times per week (d = 0.80; 95 % CI [0.64-0.96]; P < 0.001) and exercise cycles of 6-9 months (d = 0.96; 95 % CI [0.80-1.12]; P < 0.001) produced the largest effect sizes.
Conclusion:
TCM exercise therapies can effectively improve the cognitive function of the elderly. The best effect on the cognitive function of the elderly was achieved by choosing Ba Duan Jin and exercising at least five times a week for at least 60 min each time for a total of 6-9 months. The effect size of the TCM exercise therapy interventions on the cognitive function in older adults may be overestimated because of publication bias. In addition, large-sample, multicenter, high-quality randomised controlled trials should be conducted to validate this result.
