“…The findings of this study are consistent with previous reports that have shown that subjects practicing regular physical exercise are associated with better cognitive test performance, and there is a positive correlation between cardiovascular and mind–body exercise and cognitive function among the Chinese elderly 3,15. These exercises, however, might not be effective for the elderly suffering from moderate and severe dementia, who are likely to be immobile or even bed-bound.…”

“…Practicing regular physical exercise was found to be associated with better cognitive test performance and decreased arousal 3,24. A moderate exercise program followed twice a week significantly slowed, by one-third, the progressive deterioration in ability to perform activities of daily living in people with Alzheimer’s disease living in nursing homes 25.…”

“…Mind–body exercises produce effects similar to those of regular cardiovascular exercises, suggesting an alternative model of exercise for the elderly, who are less able to exercise vigorously, to lower the risk of sport-related injuries and cardiac hazards 15. Elderly people with the habit of regular physical exercise have been shown to be associated with socialization and environmental enrichment, which may also help attenuate the rate of cognitive decline 3. Tai Chi, a well-known mind–body exercise, employs cognitive tools of both visualization and focused internal awareness to strengthen, relax, and integrate the body and mind 26.…”

Background:Studies on the effect of a low intensity coordination exercise on the elderly with limited mobility are sparse. This prospective study attempted to compare the effectiveness of a customized coordination exercise and a strength exercise in improving the cognitive functioning and physical mobility on the elderly.Methods:Participants from two centers for the elderly were allocated to practice either an 8-week coordination training (CT) program or an 8-week towel exercise (TE) program. The Chinese Mini-Mental State Examination and Chinese Dementia Rating Scale (CDRS) were used to measure cognitive functioning of participants, and Timed Up-and-Go test for physical mobility. These assessments were administered before and after the program.Results:Paired t-tests showed that the CDRS scores of the CT group improved significantly from 114.8 at pre-test to 119.3 after training (P = 0.045). The CDRS scores of the TE group also improved from 114.9 at pre-test to 116.9 after training.Conclusion:Findings from this prospective study demonstrated that low-intensity level mind-body exercise could be beneficial to the cognitive functioning of older adults.

OBJECTIVES-Summarize and critically evaluate research on the effects of Tai Chi on cognitive function in older adults. DESIGN-Systematic review with meta-analysis. SETTING-Community and residential care.PARTICIPANTS-Individuals aged 60 and over (with the exception of one study) with and without cognitive impairment. MEASUREMENTS-Cognitive ability using a variety of neuropsychological testing.RESULTS-Twenty eligible studies with a total of 2,553 participants were identified that met inclusion criteria for the systematic review: 11 of the 20 eligible studies were randomized Conflict of Interest:The editor in chief has reviewed the conflict of interest checklist provided by the authors and has determined that the authors have no financial or any other kind of personal conflicts with this paper.Author Contributions: Peter M. Wayne conceived the idea for this study. In addition, Peter M. Wayne wrote the first draft, extracted data, and evaluated studies for methodological quality and risk of bias. Jacquelyn N. Walsh contributed to the first draft and extracted data. Ruth E. Taylor-Piliae conducted meta-analyses and contributed to the manuscript. Gloria Y. Yeh extracted data, evaluated studies for methodological quality and risk of bias, and contributed to the manuscript. Rebecca E. Wells, Kathryn V. Papp, and Nancy J. Donovan all contributed to the manuscript. NIH Public Access NIH-PA Author ManuscriptNIH-PA Author Manuscript NIH-PA Author Manuscript controlled trials (RCTs), 1 was a prospective non-randomized controlled study, 4 were prospective non-controlled observational studies, and 4 were cross-sectional studies. Overall quality of RCTs was modest, with 3 of 11 trials categorized as high risk of bias. Meta-analyses of outcomes related to executive function in RCTs of cognitively healthy adults indicated a large effect size when Tai Chi was compared to non-intervention controls (Hedge's g=0.90; p=0.043) and moderate effect size when compared to exercise controls (Hedge's g=0.51; p=0.003). Meta-analyses of outcomes related to global cognitive function in RCTs of cognitively impaired adults, ranging from mild cognitive impairment to dementia, showed smaller but statistically significant effects when Tai Chi was compared to both non-intervention controls (Hedge's g=0.35; p=0.004) and other active interventions (Hedge's g=0.30; p=0.002). Findings from non-randomized studies add further evidence that Tai Chi may positively impact these and other domains of cognitive function. CONCLUSION-TaiChi shows potential to enhance cognitive function in older adults, particularly in the realm of executive functioning and in those individuals without significant impairment. Larger and methodologically sound trials with longer follow-up periods are needed before more definitive conclusions can be drawn.
