RESUMO

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.

RESUMO

Metabolic syndrome (MetS) is a cluster of cardiometabolic risk factors. Many people may be unaware of their risk for MetS. A cross-sectional, descriptive study was conducted among hospitalized patients with at least one cardiometabolic risk factor in Mainland China. This study assessed the MetS knowledgelevel(through MetS Knowledge Scale, MSKS) and examined the potential predictors by regression analysis. A total of 204 patients aged 58.5 ± 10.1 years (55% males) participated in this study. The majority of participants had no history of hypertension (54%), dyslipidemia (79%), or diabetes (85%). However, 56% of these participants had at least three cardiometabolic risk factors, indicating the presence of MetS. The average MSKS was very low (mean = 36.7±18.8, possible range = 0⁻100), indicating the urgent needs of MetS education in current practice. Predictors of better MetS knowledge included higher educational level, history of dyslipidemia, and normal high-density lipoprotein cholesterol (F (8, 195) = 9.39, adjusted R² = 0.192, p< 0.001). In conclusion, adults with cardiometabolic risk factors are at risk of developing MetS, but with a low level of knowledge. Specific health education on MetS should be provided, particularly for those with limited formal education or inadequate lipid management.

RESUMO

Background: Age-related cognitive and physical decline can impair safe driving performance. Tai Chi exercise benefits cognitive and physical function and may influence safe driving performance in older adults. The primary aim of this observational study was to compare cognitive processes and physical function related to safe driving performance among older adult Tai Chi practitioners to normative reference values. Secondary aims were to examine relationships between Tai Chi exercise habits, cognitive processes, and physical function related to safe driving performance and to explore potential predictors of safe driving performance. Methods: The DrivingHealth Inventory, the Driving Scenes Test, other driving-related cognitive and physical measures, and self-reported measures including the Mindful Attention Awareness Scale (MAAS) and the Vitality Plus Scale (VPS) were collected from current Tai Chi practitioners (n = 58; age 72.9 ± 5.9 years, mean ± SD) with median >3 years Tai Chi practice. Results: Compared to normative reference values, participants performed better on numerous cognitive measures including the Driving Scenes Test (p < 0.001, d = 1.63), maze navigation (p = 0.017, d = 0.27), the Useful Field of View Test (p < 0.001, r = 0.15), and on physical measures including the Rapid Walk Test (p < 0.001, r = 0.20), and the Right Foot Tapping Test, (p < 0.001, r = 0.35). Participants scored higher than normative reference values on MAAS and VPS (p < 0.001, d = 0.75; p = 0.002, d = 0.38, respectively). Statistically significant correlations were found between several study measures. The digit span backward test was the strongest predictor of safe driving performance (ß = 0.34, p = 0.009). Conclusion: Tai Chi exercise has the potential to impact cognitive processes and physical function related to safe driving performance. Further study using randomized controlled trials, structured Tai Chi exercise doses, and driving simulator or on-road driving performance as outcome measures are warranted.

RESUMO

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.

RESUMO

BACKGROUND: Clinical practicum is a major learning component for pre-registration nursing students. Various clinical practicum models have been used to facilitate students' clinical learning experiences, employing both university-based and hospital-based clinical teachers. Considering the strengths and limitations of these clinical practicum models, along with nursing workforce shortages, we developed and tested an innovative clinical partnership model (CPM) in Hong Kong. OBJECTIVE: To evaluate an innovative CPM among nursing students actual and preferred clinical learning environment, compared with a conventional facilitation model (CFM). DESIGN: A non-randomized controlled trial examining students' clinical experiences, comparing the CPM (supervised by hospital clinical teacher) with the CFM (supervised by university clinical teacher). SETTING: One university in Hong Kong. PARTICIPANTS: Pre-registration nursing students (N = 331), including bachelor of nursing (n = 246 year three-BN) and masters-entry nursing (n = 85 year one-MNSP). METHODS: Students were assigned to either the CPM (n = 48 BN plus n = 85 MNSP students) or the CFM (n = 198 BN students) for their clinical practice experiences in an acute medical-surgical ward. Clinical teachers supervised between 6 and 8 students at a time, during these clinical practicums (duration = 4-6 weeks). At the end of the clinical practicum, students were invited to complete the Clinical Learning Environment Inventory (CLEI). Analysis of covariance was used to compare groups; adjusted for age, gender and prior work experience. RESULTS: A total of 259 students (mean age = 22 years, 76% female, 81% prior work experience) completed the CLEI (78% response rate). Students had higher scores on preferred versus actual experiences, in all domains of the CLEI. CPM student experiences indicated a higher preferred task orientation (p = 0.004), while CFM student experiences indicated a higher actual (p < 0.001) and preferred individualization (p = 0.005). No significant differences were noted in the other domains. CONCLUSIONS: The CPM draws on the strengths of existing clinical learning models and provides complementary methods to facilitate clinical learning for pre-registration nursing students. Additional studies examining this CPM with longer duration of clinical practicum are recommended.

RESUMO

BACKGROUND: Social cognitive theory (SCT) proposes that personal and environmental factors influence behavior bidirectionally. Research examining the personal and environmental factors of physical activity (PA) among African Americans (AAs) framed by SCT is scarce. PURPOSE: The purpose of this article is to enhance knowledge of SCT as a foundation for health promotion and PA research, in general, and among AAs. Findings from a previous study provide exemplars for key factors and relationships in SCT. IMPLICATIONS FOR RESEARCH AND PRACTICE: The SCT serves as a good framework for researchers studying health promotion and PA in generalamong AA parents.

RESUMO

INTRODUCTION: Tai Chi is an attractive exercise to improve cardiovascular health. This review aimed to synthesize articles written both in Chinese and in English to evaluate the effects of Tai Chi-based cardiac rehabilitation on aerobic endurance, psychosocial well-being and cardiovascular diseases risk reduction for coronary heart diseases patients. METHODS: PRISMA guidelines were used to search major health databases to identify randomized controlled trials or non-randomized controlled clinical trials that evaluated Tai Chi intervention compared with active or non-active control groups in coronary heart disease patients. When suitable, data were pooled using a random-effects meta-analysis model. RESULTS: Thirteen studies met the inclusion criteria. Tai Chi groups showed a large and significant improvement in aerobic endurance compared with both active and non-active control interventions (standard mean difference (SMD) 1.12; 95% confidence interval (CI): 0.58-1.66; p <0.001). Tai Chi groups also showed a significantly lower level of anxiety (SMD=9.28; CI: 17.46-1.10; p=0.03) and depression (SMD=9.42; CI: 13.59-5.26; p <0.001), and significantly better quality of life (SMD=0.73; 95% CI: 0.39-1.08; p <0.001) compared with non-active control groups. CONCLUSION: Significant effects of Tai Chi have been found in improving aerobic endurance and psychosocial well-being among coronary heart disease patients. Tai Chi could be a cost-effective and safe exercise option in cardiac rehabilitation. However, the effect of Tai Chi on cardiovascular disease risk reduction has not been amply investigated among coronary heart disease patients. Caution is also warranted in view of a small number of studies for this meta-analysis and potential heterogeneity in differences in the varied designs of Tai Chi intervention.

RESUMO

Falls in older adults are the result of several risk factors across biological and behavioral aspects of the person, along with environmental factors. Falls can trigger a downward spiral in activities of daily living, independence, and overall health outcomes. Clinicians who care for older adults should screen them annually for falls. A multifactorial comprehensive clinical fall assessment coupled with tailored interventions can result in a dramatic public health impact, while improving older adult quality of life. For community-dwelling older adults, effective fall prevention has the potential to reduce serious fall-related injuries, emergency room visits, hospitalizations, institutionalization, and functional decline.

RESUMO

Current medical treatments for Parkinson's disease (PD) are mainly palliative, though research indicates Tai Chi exercise improves physical function and well-being. An electronic database search of PubMed, CINAHL, Web of Science, Cochrane Library, PsycINFO and Embase was conducted, to examine current scientific literature for potential benefits of Tai Chi on physical function and well-being among persons with PD. A total of 11 studies met the inclusion criteria: 7 randomized clinical trials and 4 quasi-experimental studies. PD participants (n = 548) were on average age 68 years old and 50% women. Overall, participants enrolled in Tai Chi had better balance and one or more aspect of well-being, though mixed results were reported. Further research is needed with more rigorous study designs, larger sample sizes, adequate Tai Chi exercise doses, and carefully chosen outcome measures that assess the mechanisms as well as the effects of Tai Chi, before widespread recommendations can be made.

RESUMO

OBJECTIVES: Conduct a systematic review to evaluate the effects of Tai Chi on physical and psychosocial function among individuals with Multiple Sclerosis. METHODS: An electronic literature search of 12 databases using controlled vocabulary function and keywords from inception through August 2016. All Tai Chi intervention studies assessing physical and psychosocial function among persons with Multiple Sclerosis were included. Study quality was scored using an established tool examining 16 study elements (range=0-32). RESULTS: A total of 91 articles were retrieved, with 3 additional articles identified through reviewing bibliographies of relevant articles. A total of 8 studies (randomized controlled trials, n=3; quasi-experimental, n=5) enrolled 193 participants with Multiple Sclerosis. Studies were conducted in the USA (n=3), Europe (n=3), Iran, (n=1), and India (n=1). A total of 3 studies reported using the Yang style of Tai Chi (not specified, n=5 studies). The Tai Chi intervention averaged 27 sessions over 11 weeks. Study quality scores for the randomized controlled trials had a mean score of 23 (range 19-26), while quality scores for quasi-experimental studies had a mean score of 20 (range 13-26). Overall, participants enrolled in Tai Chi had better balance, gait and flexibility, less fatigue and depression, and better quality of life after the intervention; though mixed results were reported. CONCLUSION: The results indicate that Tai Chi is likely safe and may provide physical and psychosocial benefits in individuals with Multiple Sclerosis. Further research is needed using more rigorous study designs to assess the benefits of Tai Chi for individuals with Multiple Sclerosis.

RESUMO

PURPOSE: The objectives of this pilot study for women breast cancer survivors with lymphedema was 1) to evaluate recruitment rates, retention rates, adherence to Bowenwork (a noninvasive complementary therapy involving gentle muscle movements), home exercises, safety and comfort; 2) determine the effect of Bowenwork on quality of life (QOL), functional status, perceived pain, range of motion (ROM), arm/ankle circumference (to assess for localized and systemic changes). METHODS: Participants received 4 Bowenwork sessions with home exercises. Initial and post assessments included QOL, functional status, and pain. ROM, arm/ankle circumference and pain measures were recorded before each session. RESULTS: Twenty-one women enrolled in the study; 95% completion; adherence 100%; home exercises 95%; no adverse events. The intervention improved mental health (SF-36-MCS); breast cancer-related functional (FACT-B); increased ROM; reduced arm circumferences. P value set at <0.05. CONCLUSIONS: The Bowenwork intervention was safe and acceptable for women breast cancer survivors with lymphedema.

RESUMO

BACKGROUND: Self-management after a stroke is a challenge because of multifaceted care needs and complex disabling consequences that cause further hindrance to patient participation. A 13-week stroke patient empowerment intervention (Health Empowerment Intervention for Stroke Self-management [HEISS]) was developed to enhance patients' ability to participate in self-management. PURPOSE: To examine the effects of the empowerment intervention on stroke patients' self-efficacy, self-management behavior, and functional recovery. METHODS: This is a single-blind randomized controlled trial with stroke survivors assigned to either a control group (CG) receiving usual ambulatory rehabilitation care or the HEISS in addition to usual care (intervention group [IG]). Outcome data were collected at baseline (T0), 1 week (T1), 3 months (T2), and 6 months (T3) postintervention. Data were analyzed on the intention-to-treat principle. The generalized estimating equation model was used to assess the differential change of self-efficacy in illness management, self-management behaviors (cognitive symptom management, communication with physician, medication adherence, and self-blood pressure monitoring), and functional recovery (Barthel and Lawton indices) across time points (baseline = T0, 1 week = T1, 3 months = T2, and 6 months = T3 postintervention) between the two groups. RESULTS: A total of 210 (CG =105, IG =105) Hong Kong Chinese stroke survivors (mean age =69 years, 49% women, 72% ischemic stroke, 89% hemiparesis, and 63% tactile sensory deficit) were enrolled in the study. Those in IG reported better self-efficacy in illness management 3-month (P=0.011) and 6-month (P=0.012) postintervention, along with better self-management behaviors at all follow-up time points (all P<0.05), apart from medication adherence (P>0.05). Those in IG had significantly better functional recovery (Barthel, all P<0.05; Lawton, all P<0.001), compared to CG. The overall dropout rate was 16.7%. CONCLUSION: Patient empowerment intervention (HEISS) may influence self-efficacy in illness management and improve self-management behavior and functional recovery of stroke survivors. Furthermore, the HEISS can be conducted in parallel with existing ambulatory stroke rehabilitation services and provide added value in sustaining stroke self-management and functional improvement in the long term.

RESUMO

As the number of older adults in the United States grows, the number of automobile drivers over the age of 65 will also increase. Several cognitive processes necessary for automobile driving are vulnerable to age-related decline. These include declines in executive function, working memory, attention, and speed of information processing. The benefits of physical activity on physical, psychological and particular cognitive processes are well-documented; however few studies have explored the relationship between physical activity and driving ability in older adults or examined if cognitive processes mediate (or moderate) the effect of physical activity on driving ability. The purpose of this paper is to review the existing literature regarding physical activity, cognition and automobile driving. Recommendations for further research and utility of the findings to nursing and the health care team are provided.

RESUMO

BACKGROUND: Few studies of the association between prospective falls and sensor-based measures of motor performance and physical activity (PA) have evaluated subgroups of frailty status separately. OBJECTIVE: To evaluate wearable sensor-based measures of gait, balance, and PA that are predictive of future falls in community-dwelling older adults. METHODS: The Arizona Frailty Cohort Study in Tucson, Arizona, followed community-dwelling adults aged 65 years and over (without baseline cognitive deficit, severe movement disorders, or recent stroke) for falls over 6 months. Baseline measures included Fried frailty criteria: in-home and sensor-based gait (normal and fast walk), balance (bipedal eyes open and eyes closed), and spontaneous daily PA over 48 h, measured using validated wearable technologies. RESULTS: Of the 119 participants (36% non-frail, 48% pre-frail, and 16% frail), 48 reported one or more fall (47% of non-frail, 33% of pre-frail, and 47% of frail). Although balance deficit and PA were independent fall predictors in pre-frail and frail groups, they were not sensitive to predict prospective falls in the non-frail group. Even though gait performance deteriorated as frailty increased, gait was not a predictor of prospective falls when participants were stratified based on frailty status. In pre-frail and frail participants combined, center of mass sway [odds ratio (OR) = 5.9, 95% confidence interval (CI) 2.6-13.7], PA mean walking bout duration (OR = 1.1, 95% CI 1.0-1.2), PA mean standing bout duration (OR = 0.94, 95% CI 0.91-0.99), and a fall in previous 6 months (OR = 7.3, 95% CI 1.5-36.4) were independent predictors of prospective falls (area under the curve: 0.882). CONCLUSION: This study suggests that independent predictors of falls are dependent on frailty status. Among sensor-derived parameters, balance deficit, longer typical walking episodes, and shorter typical standing episodes were the most sensitive predictors of prospective falls in the combined pre-frail and frail sample. Gait deficit was not a sensitive fall predictor in the context of frailty status.
