Tailored Sitting Tai Chi Program for Subacute Stroke Survivors: A Randomized Controlled Trial.

BACKGROUND: The initiation of exercise during rehabilitation at the subacute stage could provide stroke survivors with an approach to recovery that capitalizes on unique physiological conditions and promotes spontaneous recovery. We aimed to examine the effects of a tailored sitting Tai Chi program on recovery outcomes among subacute stroke survivors. METHODS: We conducted a 12-week assessor-blind randomized controlled trial in China. Subacute stroke survivor-caregiver dyads were recruited and randomly assigned to either the sitting Tai Chi group (n=80) or attention control group (n=80). Outcomes including upper limb function (Fugl-Meyer Assessment Upper Extremity & Wolf Motor Function Test), balance control (Berg Balance Scale), sitting balance control (Trunk Impairment Scale), depressive symptoms (Geriatric Depression Scale Short Form), shoulder range of motion, shoulder pain (ShoulderQ), activities of daily living (Modified Barthel Index), and quality of life (Stroke Specific Quality of Life Scale) were measured at baseline, in-process, immediately post, and 4-week postintervention. RESULTS: Immediately postintervention, the sitting Tai Chi group (n=69) showed significant upper limb function improvement in the primary outcomes including the performance time (regression coefficient of the group-by-time interaction, B=-21.415 [95% CI, -31.000 to -11.831]) and functional ability (B=10.146 [95% CI, 4.886-15.406]) domains of the Wolf Motor Function Test, balance control (B, 4.972 [95% CI, 1.356-8.588]), and sitting balance control (B=4.397 [95% CI, 2.699-6.096]). Compared with the control group (n=65), improvements were also observed in secondary outcomes including depressive symptoms (B=-1.626 [95% CI, -2.304 to -0.948]), shoulder extension (B=4.518 [95% CI, 0.893-8.144]), activities of daily living (B=5.510 [95% CI, 0.450-10.569]), and quality of life (B=15.680 [95% CI, 7.255-24.105]). CONCLUSIONS: The results support the effectiveness of a tailored sitting Tai Chi program in improving recovery outcomes among subacute stroke survivors and provide additional knowledge to support the clinical implementation of such a program.

Group- plus home-based Tai Chi program improves functional health among patients with coronary heart disease: a randomized controlled trial.

AIMS: Tai Chi is a promising exercise option in cardiac rehabilitation to manage coronary heart disease (CHD). Increasing attention was paid on home-based cardiac rehabilitation to improve participation rate, but no study has yet emphasized the effect of home-based Tai Chi. A single-blinded randomized controlled trial is used to examine the effects of a group- plus home-based Tai Chi program on functional health. METHODS AND RESULTS: Ninety-eight community-dwelling patients with CHD were randomly assigned to the Tai Chi and control groups. Participants in the Tai Chi group attended 6-week group- plus 6-week home-based Tai Chi program. Outcome measures included physical functions, cardiovascular risk factors, and exercise self-efficacy. Data were collected at baseline, 6-week, 12-week, and 24-week. Intervention effects were analysed using the generalized estimating equation model. Compared with changes in the control group, the intervention group achieved significant improvements in aerobic endurance, lower-body strength, agility and dynamic balance, diastolic blood pressure, and exercise self-efficacy over the 24-week study period (all Ps < 0.05). Intervention adherence was high (79.6% of participants attending >75% of all Tai Chi sessions). CONCLUSIONS: This Tai Chi program significantly improved the functional health of patients with CHD, indicating that Tai Chi could be taught in group sessions and then continued independently as a home exercise routine for health promotion.

Psychometric Properties of the Translated Tai Chi Exercise Self-Efficacy Scale for Chinese Adults with Coronary Heart Disease or Risk Factors.

Tai Chi is an effective exercise option for individuals with coronary heart disease or its associated risk factors. An accurate and systematic assessment of a Mandarin-speaking adults' self-efficacy in maintaining Tai Chi exercise is lacking. Mandarin Chinese has the most speakers worldwide. This study aimed to translate the Tai Chi Exercise Self-Efficacy scale and examine its psychometric properties. The 14-item Tai Chi Exercise Self-Efficacy scale was translated from English into Mandarin Chinese using a forward-translation, back-translation, committee approach, and pre-test procedure. Participants with coronary heart disease or risk factors (n = 140) enrolled in a cross-sectional study for scale validation. Confirmatory factor analysis indicated a good fit of the two-factor structure (Tai Chi exercise self-efficacy barriers and performance) to this sample. The translated scale demonstrated high internal consistency, with a Cronbach's α value of 0.97, and good test-retest reliability, with an intra-class correlation coefficient of 0.86 (p < 0.01). Participants with prior Tai Chi experience reported significantly higher scores than those without (p < 0.001), supporting known-group validity. A significant correlation was observed between the translated scale and total exercise per week (r = 0.37, p < 0.01), providing evidence of concurrent validity. The Mandarin Chinese version of the Tai Chi Exercise Self-Efficacy scale is a valid and reliable scale for Chinese adults with coronary heart disease or risk factors.

Tai Chi in Chinese adults with metabolic syndrome: A pilot randomized controlled trial.

OBJECTIVE: To determine the feasibility, acceptability and effects of a 12-week Tai Chi exercise program on cardiometabolic risk factors and quality of life in community-dwelling Chinese adults with metabolic syndrome. DESIGN: A single blind, pilot randomized controlled trial. SETTING/LOCATION: A general outpatient clinic of a community-based hospital in Hong Kong. SUBJECTS: Ethnic Chinese, 18 years and older, who had at least three of the five criteria of metabolic syndrome defined by the National Cholesterol Education- Adult Treatment Panel III. INTERVENTION: The Tai Chi group attended a 1 -h Tai Chi class, twice a week for 12 weeks, plus 30-minutes home practice three-times per week. The control group maintained their usual daily activities. OUTCOME MEASURES: Primary outcomes were feasibility and acceptability of the Tai Chi intervention. Secondary outcome measures were cardiometabolic risk factors, quality of life, stress and Tai Chi exercise self-efficacy. RESULTS: Study retention rate was 65% (n = 35). Overall satisfaction of completers with the Tai Chi intervention was 4.5 ±â€¯0.63 (possible range = 1-5). When compared to controls, the Tai Chi group had significantly lower systolic blood pressure (p = 0.037) at 12-weeks. Significant within group changes for the Tai Chi group included lower diastolic blood pressure (p = 0.015), higher fasting blood glucose (p = 0.009), higher waist circumference (females only, p = 0.007), and better perceived mental health (p = 0.046); while controls had significantly higher fasting blood glucose (p = 0.031), and higher waist circumference (females only, p = 0.003). CONCLUSION: The study intervention was feasible and acceptable for Chinese adults with metabolic syndrome. While not powered to find statistically significant differences, positive and negative changes were observed in some cardiometabolic risk factors and quality of life. Further investigation with a larger sample size and longer study period is needed to explore potential environmental factors that may have influenced the study results.

Tai Chi exercise is more effective than brisk walking in reducing cardiovascular disease risk factors among adults with hypertension: A randomised controlled trial.

BACKGROUND: Physical inactivity is a major modifiable lifestyle risk factor associated with cardiovascular disease. Tai Chi is a safe and popular form of physical activity among older adults, yet direct comparisons are lacking between Tai Chi and brisk walking in their ability to reduce cardiovascular disease risk factors and improve psychosocial well-being. METHODS: 246 adults (mean age = 64.4 ± 9.8 years, age range = 30-91 years, 45.5% men) with hypertension and at least two but not more than three modifiable cardiovascular disease risk factors (diabetes, dyslipidaemia, overweight, physical inactivity and smoking) were randomly assigned to either Tai Chi (n = 82), brisk walking (n = 82) or control (n = 82) groups. The Tai Chi and brisk walking groups engaged in moderate-intensity physical activity 150 min/week for 3 months; daily home-based practice was encouraged for another 6 months. The primary outcome was blood pressure. Secondary outcomes were fasting blood sugar, glycated haemoglobin, total cholesterol, triglycerides, high- and low-density lipoprotein, body mass index, waist circumference, aerobic endurance, perceived stress, quality of life and exercise self-efficacy. Data were collected at baseline, post-intervention at 3 months and follow-up assessments at 6 and 9 months. Generalised estimating equation models were used to compare the changes in outcomes over time between groups. RESULTS: At baseline, the participants had an average blood pressure = 141/81 and average body mass index = 26; 58% were diabetics, 61% presented with dyslipidemia and 11% were smokers. No significant difference was noted between groups. Tai Chi significantly lowered blood pressure (systolic -13.33 mmHg; diastolic -6.45 mmHg), fasting blood sugar (-0.72 mmol/L), glycated haemoglobin (-0.39%) and perceived stress (-3.22 score) and improved perceived mental health (+4.05 score) and exercise self-efficacy (+12.79 score) at 9 months, compared to the control group. In the Tai Chi group, significantly greater reductions in blood pressure (systolic -12.46 mmHg; diastolic -3.20 mmHg), fasting blood sugar (-1.27 mmol/L), glycated haemoglobin (-0.56%), lower perceived stress (-2.32 score), and improved perceived mental health (+3.54 score) and exercise self-efficacy (+12.83 score) were observed, compared to the brisk walking group. No significant changes in the other cardiovascular disease risk indicators were observed over time between groups. CONCLUSION: Nurses play a key role in promoting exercise to reduce cardiovascular disease risk and foster a healthy lifestyle among adults. Tai Chi is better than brisk walking in reducing several cardiovascular disease risk factors and improving psychosocial well-being, and can be recommended as a viable exercise for building a healthy life free of cardiovascular disease.
