Effects of Tai Chi Chuan on Inhibitory Control in Elderly Women: An fNIRS Study.

ABSTRACT: Background:Inhibitory control is a sub-ability of executive function and plays an important role in the entire cognitive process. However, declines in inhibitory control during aging significantly impair the quality of life of elderly people. Investigating methods to delay the decline of inhibitory control has become a focal point in current research. Tai Chi Chuan (TCC) is one effective method used to delay cognitive declines in older adults. However, the specific effects of TCC on inhibitory control and the mechanisms through which TCC may improve cognition in older adults have not been comprehensively investigated. Objective:The study explores possible neurological mechanisms related to the effects of TCC interventions on inhibitory control in older people using a functional near-infrared spectroscopy (fNIRS) technique and reaction times (RTs). Methods:A total of 26 healthy, elderly people who had not received TCC training completed all study procedures. The subjects were randomized to either the TCC group or the control group. Subjects in the TCC group were taught TCC by a certified instructor and trained for 8 weeks. The control group continued to perform general daily activities. The Flanker task was administered to every participant to evaluate inhibitory control pre- and post-intervention. While participants were performing the Flanker task, fNIRS data were collected. Results:Post-intervention, significant differences for incongruent flankers were found only for the TCC intervention group. Faster RTs were observed for the incongruent flankers in the TCC group than in the control group (p < 0.05). Analysis of the fNIRS data revealed an increase in oxy-Hb in the prefrontal cortex during the incongruent flankers after the TCC exercise intervention. Conclusion:The TCC intervention significantly improved inhibitory control in older adults, suggesting that TCC is an effective, suitable exercise for improving executive function and neurological health in elderly people.

Project description:BackgroundMany elderly individuals who experience sleep disturbances would consider complementary and alternative medicine as an alternative therapeutic option in light of the limitations of traditional treatments. Mindfulness-based interventions (MBIs) and Tai Chi Chuan (TCC) are two alternative forms of complementary and alternative medicine. They both share the common feature of a focus on breathing but represent distinct approaches with different mechanisms and philosophical orientations. The trial described in this protocol aims to evaluate the effects of an integrated form of mindfulness-based Tai Chi Chuan (MBTCC) programme and the underlying mechanisms of the beneficial effects over a 12-month follow-up.MethodsThe planned study is a four-armed randomized controlled trial with repeated measures. A total of 256 community-dwelling older adults with sleep problems will be recruited and randomized into four groups: (1) an MBTCC group, (2) an MBI group, (3) a TCC group, and (4) a sleep hygiene education (SHE) control group. The outcome measures in terms of insomnia severity, interoception, sleep-wake pattern, health status, rumination, and hyperarousal level will be collected at four time points: at baseline (T1), after the 8-week intervention (T2), 6 months after the intervention (T3), and 1 year after the intervention (T4). In addition, qualitative evaluation through focus group interviews will be conducted at the end of the 12-month assessment period (T4).DiscussionThis trial will illuminate the synergetic effect of combining both MBIs and TCC on optimizing improvements in sleep disturbance. The findings from this study can provide empirical support for this integrated treatment, which provides an alternative for healthcare professionals in elderly service to select appropriate practices to treat elderly people with sleep disturbance. It can further help to lessen the growing public health burden of sleep disturbances among the elderly living in the community.Trial registrationClinicalTrials.gov . NCT05396092 .

Project description:Background: Tai Chi Chuan(TCC), as a mind-body exercise, may have a positive impact on physical function and psychological well-being in breast cancer patients. The latest systematic review and meta-analysis of TCC for breast cancer was made 4 years ago and some new clinical trials about it were published. We remade a systematic review and meta-analysis to evaluate the effect of TCC in breast cancer patients. Methods: In this systematic review and meta-analysis, we searched MEDLINE (via PubMed), EMBASE (via embase.com), CENTRAL, CNKI, COVIP, Wanfang, Chaoxing, CiNii, J-SSTAGE, DBpia, and ThaiJO with no language restrictions from inception to December 31, 2018 (updated on February 16, 2020), for randomized clinical trials comparing TCC with non-exercised therapy in breast cancer patients. The primary outcome was quality of life in patients with breast cancer and data pooled by a random-effects model. Subgroup analyses were conducted to estimate the effect of different durations of TCC for breast cancer patients. This study was registered in PROSPERO, number CRD 4201810326. Results: Fifteen articles involving a total of 885 breast cancer participants were included in this review. Compared with non-exercised therapy, TCC had a significant effect on quality of life in breast cancer patients (SMD = 0.37, 95% CI 0.15-0.59, p = 0.001), and subgroup analysis found that TCC showed beneficial effect in 12 weeks and 25 weeks (12 weeks: SMD = 0.40, 95% CI 0.19-0.62, p = 0.0003; 25 weeks: SMD = 0.38, 95% CI 0.15-0.62, p = 0.002). Meta-analyses of secondary outcomes showed that 3 weeks TCC increased shoulder function (SMD = 1.08, 95% CI 0.28-1.87, p = 0.008), 12 weeks TCC improved pain (SMD = 0.30, 95% CI 0.08-0.51, p = 0.007), shoulder function (SMD = 1.34, 95% CI 0.43-2.25, p = 0.004), strength of arm (SMD = 0.44, 95% CI 0.20-0.68, p = 0.0004), and anxiety (MD = -4.90, 95% CI -7.83 to -1.98, p = 0.001) in breast cancer patients compared with the control group. Conclusions: TCC appears to be effective on some physical and psychological symptoms and improves the quality of life in patients with breast cancer. Additional randomized controlled trials with a rigorous methodology and low risk of bias are needed to provide more reliable evidence.

Project description:BackgroundRheumatoid arthritis (RA) has been known to be associated with increased risk of cardiovascular disease (CVD). The aim of this study was to investigate the effects of Tai Chi exercise on CVD risk in elderly women with RA.MethodIn total, 56 female patients with RA were assigned to either a Tai Chi exercise group (29 patients) receiving a 3-month exercise intervention once a week or a control group (27 patients) receiving general information about the benefits of exercise. All participants were assessed at baseline and at 3 months for RA disease activity (Disease Activity Score 28 and Routine Assessment of Patient Index Data 3), functional disability (Health Assessment Questionnaire), CVD risk factors (blood pressure, lipids profile, body composition, and smoking), and three atherosclerotic measurements: carotid intima-media thickness, flow-mediated dilatation (FMD), and brachial-ankle pulse wave velocity (baPWV).ResultsFMD, representative of endothelial function, significantly increased in the Tai Chi exercise group (initial 5.85 ± 2.05 versus 3 months 7.75 ± 2.53%) compared with the control group (initial 6.31 ± 2.12 versus 3 months 5.78 ± 2.13%) (P = 1.76 × 10(-3)). Moreover, baPWV, representative of arterial stiffness, significantly decreased in the Tai Chi exercise group (initial 1693.7 ± 348.3 versus 3 months 1600.1 ± 291.0 cm/s) compared with the control group (initial 1740.3 ± 185.3 versus 3 months 1792.8 ± 326.1 cm/s) (P = 1.57 × 10(-2)). In addition, total cholesterol decreased significantly in the Tai Chi exercise group compared with the control group (-7.8 ± 15.5 versus 2.9 ± 12.2 mg/dl, P = 2.72 × 10(-2)); other changes in RA-related characteristics were not significantly different between the two groups. Tai Chi exercise remained significantly associated with improved endothelial function (FMD; P = 4.32 × 10(-3)) and arterial stiffness (baPWV; P = 2.22 × 10(-2)) after adjustment for improvement in total cholesterol level.ConclusionTai Chi exercise improved endothelial dysfunction and arterial stiffness in elderly women with RA, suggesting that it can be a useful behavioral strategy for CVD prevention in patients with RA.
