RESUMO

Exercise-based training decreases hospitalizations in heart failure patients but such patients have exercise intolerance. The objectives of the study were to evaluate the effect of 12 weeks of Tai Chi exercise and lower limb muscles' functional electrical stimulation in older chronic heart failure adults. A total of 1,084 older adults with chronic systolic heart failure were included in a non-randomized clinical trial (n=271 per group). The control group did not receive any kind of intervention, one group received functional electrical stimulation of lower limb muscles (FES group), another group practiced Tai Chi exercise (TCE group), and another received functional electrical stimulation of lower limb muscles and practiced Tai Chi exercise (FES & TCE group). Quality of life and cardiorespiratory functions of all patients were evaluated. Compared to the control group, only FES group had increased Kansas City Cardiomyopathy Questionnaire (KCCQ) score (P<0.0001, q=9.06), only the TCE group had decreased heart rate (P<0.0001, q=5.72), and decreased peak oxygen consumption was reported in the TCE group (P<0.0001, q=9.15) and FES & TCE group (P<0.0001, q=10.69). FES of lower limb muscles and Tai Chi exercise can recover the quality of life and cardiorespiratory functions of older chronic heart failure adults (trial registration: Research Registry 4474, January 1, 2015).

RESUMO

BACKGROUND: Sleep plays a crucial role in the general health of the human body. However, sleep problems become increasingly severe with age, and its incidence is on the rise. Notably, Tai Chi exercise may be an efficacious means to ameliorate sleep problems among older adults. This is especially since Tai Chi has been widely used to manage sleep problems in China for many years, but there is limited evidence regarding its effectiveness. We will conduct this study aiming to investigate the efficacy of Tai Chi as a complementary and alternative therapy for sleep problems in older adults. METHODS: We will systematically search Scopus, Embase, PubMed, Cochrane Library, China National Knowledge Infrastructure, and Wanfang database from their inceptions to August 2019. Only randomized controlled trials of Tai Chi for sleep problems among older adults will be considered for inclusion and the Pittsburgh sleep quality index will be the primary outcome measurement. Moreover, study selection, data extraction, and the evaluation of the methodological quality of trials will each be independently completed by at least 2 researchers. We will employ the software Stata version 12.0 to implement the statistical analysis. RESULTS: The current systematic review and meta-analysis will provide synthesized results of the effectiveness and safety of Tai Chi exercise for sleep problems among older adults. CONCLUSION: This systematic review and meta-analysis will provide high-quality evidence on the effectiveness and safety of Tai Chi exercise for sleep problems in older adults.

RESUMO

BACKGROUND: Mild cognitive impairment (MCI) is an intermediate stage between the cognitive changes of normal aging and early dementia. Tai Chi (TC) may be particularly beneficial to patients with MCI due to its whole-body coordination characteristics. This systematic review protocol aims to outline the methods that will be used to assess the comparative effectiveness and safety of TC for MCI through a systematic review and meta-analysis. METHODS: A systematic review will identify and evaluate randomized controlled trials (RCTs) that examined the effects and safety of TC compared to a placebo, conventional treatment, and no treatment on cognitive function in individuals with MCI. Studies from databases of MEDLINE, PubMed, Embase, Global Health, Cochrane Library, and Scopus from January 1990 to March 2019 reported in English will be searched. Two independent reviewers will screen the studies for inclusion with the eligibility criteria and extract data. Risk of bias of individual studies will be assessed in line with Cochrane risk of bias tool. The overall quality of cumulative evidence will be assessed using selected Grading of Recommendations, Assessment, Development, and Evaluations criteria. Statistics will be used for heterogeneity assessment, sensitivity analysis, data synthesis, generating funnel plots, and subgroup analysis. Meta-analysis will be performed, if sufficiently homogeneous studies are found. A narrative synthesis will be conducted, grouping studies by exposure and outcome definitions, and describing any differences by subgroups. RESULTS: This study will provide practical and targeted evidence in investigating the impact of TC exercise for individuals with MCI. CONCLUSION: The findings of our study will provide updated evidence to determine whether TC is an effective intervention to patients with MCI. TRIAL REGISTRATION NUMBER: International Prospective Register for Systematic Reviews (PROSPERO) number CRD42019125104.

RESUMO

To research the possible role of Tai Chi in preventing cardiovascular disease and improving cardiopulmonary function in adults with obesity aged 50 years and older.Between 2007 and 2012, 120 adults with obesity, aged 50 years and older, were divided into a Tai Chi group and a control group, with 60 participants in each group. The 2 groups were evaluated for weight, waist circumference, hip circumference, blood pressure (BP), body mass index, and incidence of chronic disease during follow-up monitoring.Two- and 6-year follow-up showed that the average BP in the Tai Chi group along with either the systolic or diastolic pressure decreased significantly compared to those in the control group (P < .001). Waist and hip circumference, weight, and body mass index in the Tai Chi group were significantly reduced compared to those in the control group (P < .001). The cardiopulmonary function of the control group and the Tai Chi group changed, with the cardiac index significantly higher in the Tai Chi group than in the control group (P < .05). The Tai Chi group had significantly higher levels of lung function, including vital capacity, maximal oxygen uptake, and total expiratory time, than the control group. The total incidence of complications and mortality in the Tai Chi group were much lower than those in the control group (P < .001). The incidence of cardiovascular and cerebrovascular disease in the Tai Chi group (16.67%) was lower than that in the control group (38.33%).Tai Chi is not only a suitable exercise for elderly people with obesity, but it can also help to regulate BP, improve heart and lung function in these individuals, as well as reduce the incidence of cardiovascular disease and other chronic diseases, helping to improve their quality of life.

RESUMO

BACKGROUND: This is the first systematic review evaluating and statistically synthesis the current studies regarding the effects of Tai Chi on pain and disability in patients with low back pain (LBP). METHODS: Seven electronic databases including PubMed, EMBASE, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang and VIP information from inception to early March 2019 were searched. The Physiotherapy Evidence Database (PEDro) Scale was used to assess quality of all included randomized controlled trials (RCTs). The pooled effect size (weight mean difference, WMD) and 95% confidence interval (CI) were calculated to determine the effect of Tai Chi on pain and disability among LBP patients based on random effects model. RESULTS: The aggregated results of the meta-analysis suggested that Tai Chi significantly decreased pain (WMD = -1.27, 95%CI -1.50 to -1.04, P < .00001, I = 74%) and improve function disability, Oswestry disability index (ODI) subitems: pain intensity (WMD = -1.70, 95% CI -2.63 to -0.76, P = .0004, I = 89%); personal care (WMD = -1.93, 95% CI -2.86 to -1.00, P < .0001, I = 90%); lifting (WMD = -1.69, 95% CI -2.22 to -1.15, P < .0001, I = 66%); walking (WMD = -2.05, 95% CI -3.05 to -1.06, P < .0001, I = 88%); standing (WMD = -1.70, 95% CI -2.51 to -0.89, P < .0001, I = 84%); sleeping (WMD = -2.98, 95% CI -3.73 to -2.22, P < .00001, I = 80%); social life (WMD = -2.06, 95% CI -2.77 to -1.35, P < 0.00001, I = 80%) and traveling (WMD = -2.20, 95% CI -3.21 to -1.19, P < .0001, I = 90%), Japanese Orthopedic Association (JOA) score (WMD = 7.22, 95% CI 5.59-8.86, P < .00001, I = 0%), Medical Outcomes Study Questionnaire Short Form 36 Health Survey (SF-36) physical functioning (WMD = 3.30, 95% CI 1.92-4.68, P < .00001), and Roland-Morris Disability Questionnaire (RMDQ) (WMD = -2.19, 95% CI -2.56 to -1.82, P < .00001). CONCLUSION: We drew a cautious conclusion that Tai Chi alone or as additional therapy with routine physical therapy may decrease pain and improve function disability for patients with LBP. Further trials are needed to be conducted with our suggestions mentioned in the systematic review.

RESUMO

Older people face difficulty engaging in conventional rehabilitation exercises for improving physical functions over a long time period due to the passive nature of the conventional exercise, inconvenience, and cost. This study aims to develop and validate a dynamic time warping (DTW) based algorithm for assessing Kinect-enabled home-based physical rehabilitation exercises, in order to support auto-coaching in a virtual gaming environment. A DTW-based algorithm was first applied to compute motion similarity between two time series from an individual user and a virtual coach. We chose eight bone vectors of the human skeleton and body orientation as the input features and proposed a simple but innovative method to further convert the DTW distance to a meaningful performance score in terms of the percentage (0-100%), without training data and experience of experts. The effectiveness of the proposed algorithm was validated through a follow-up experiment with 21 subjects when playing a Tai Chi exergame. Results showed that the algorithm scores had a strong positive linear relationship (r = 0.86) with experts' ratings and the calibrated algorithm scores were comparable to the gold standard. These findings suggested that the DTW-based algorithm could be effectively used for automatic performance evaluation of an individual when performing home-based rehabilitation exercises.

RESUMO

PURPOSE: The aim of the study was to assess the feasibility, safety, and preliminary estimates of effectiveness of Tai Chi on functional outcomes in stroke survivors. DESIGN: A mixed-method study with a single-group repeated-measure design and in-depth interviews. METHODS: Fourteen stroke survivors with hemiplegia were recruited to participate in a Tai Chi program, twice weekly for 12 months. Outcomes included physical function, self-efficacy, and activity of daily living measured at 3-month intervals for 12 months. FINDINGS: Ten participants (mean age, 68.5 years) completed all assessments with significantly improved balance (χ = 14.08, p = .007), flexibility (χ = 11.70, p = .020), and self-efficacy (χ = 21.84, p < .001) over 12 months. Qualitative results highlighted the positive impact on physical improvement, psychological well-being, social support, and improved confidence in performing activities of daily living. CONCLUSION: An adapted Tai Chi program was safe, feasible, and well received in community-dwelling stroke survivors. CLINICAL RELEVANCE: The Tai Chi-based rehabilitation program shows promise for improving function and balance outcomes related to fall prevention in stroke survivors.

RESUMO

Purpose: This systematic review examines intervention studies using Tai Chi in the early stages of dementia to determine the effectiveness of Tai Chi for the short-term improvement of cognitive functions for elderly persons with the disease. Methods: A keyword search was done in PubMed/MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Excerpta Medica Database (EMBASE), and Cochrane Library databases using keywords such as Tai Chi, Dementia*, and cognition. A secondary search strategy consisting of a manual search in the reference lists of selected articles was also used. Results: A total of nine studies were reviewed including six randomized controlled trials, two non-randomized controlled trials, and one non-randomized prospective study. The studies suggest Tai Chi has impacts on global cognitive functions, visuospatial skills, semantic memory, verbal learning/memory, and self-perception of memory. The effects of Tai Chi on overall cognition for people with mild cognitive impairment are comparable to those in control groups which engaged in exercise. Conclusion: The studies reviewed affirm the potential of Tai Chi to improve short-term cognitive function in the elderly at the onset of dementia.

RESUMO

Objective: The aim of this meta-analytic review was to quantitatively examine the effects of traditional Chinese exercises (TCE) on pain intensity and back disability in individuals with low back pain (LBP). Methods: Potential articles were retrieved using seven electronic databases (Medline, Embase, Cinahl, Web of Science, Cochrane library, China National Knowledge Infrastructure, and Wanfang). The searched period was from inception to 1 March 2019. Randomized controlled trials (RCTs) assessing the effect of TCE on pain intensity and back disability in LBP patients were included. Pooled effect sizes were calculated using the random-effects models and 95% confidence interval (95% CI). Results: Data from eleven RCTs (886 individuals with LBP) meeting the inclusion criteria were extracted for meta-analysis. Compared with the control intervention, TCE induced significant improvements in the visual analogue scale (VAS) (Hedge's g = -0.64, 95% CI -0.90 to -0.37, p < 0.001), Roland-Morris Disability Questionnaire (RMDQ) (Hedge's g = -0.41, 95% CI -0.79 to -0.03, p = 0.03), Oswestry Disability Index (ODI) (Hedge's g = -0.96, 95% CI -1.42 to -0.50, p < 0.001), and cognitive function (Hedge's g = -0.62, 95% CI -0.85 to -0.39, p < 0.001). In a meta-regression analysis, age (ß = 0.01, p = 0.02) and total exercise time (ß = -0.0002, p = 0.01) were associated with changes in the VAS scores, respectively. Moderator analyses demonstrated that Tai Chi practice (Hedge's g = -0.87, 95% CI -1.38 to -0.36, p < 0.001) and Qigong (Hedge's g = -0.54, 95% CI -0.86 to -0.23, p < 0.001) reduced VAS scores. Interventions with a frequency of 1-2 times/week (Hedge's g = -0.53, 95% CI -0.98 to -0.07, p = 0.02) and 3-4 times/week (Hedge's g = -0.78, 95% CI -1.15 to -0.42, p < 0.001) were associated with reduced VAS scores, but this significant reduction on this outcome was not observed in the weekly training frequency of ≥5 times (Hedge's g = -0.54, 95% CI -1.16 to 0.08, p = 0.09). Conclusions: TCE may have beneficial effects for reducing pain intensity for individuals with LBP, regardless of their pain status.

RESUMO

OBJECTIVE: To systematically synthesize and critically evaluate evidence on the effects of tai chi for patients with type 2 diabetes mellitus. DATA SOURCES: Seven electronic databases (Wan Fang, SinoMed, China National Knowledge Infrastructure, VIP, PubMed, Embase, and Cochrane Library) were systematically searched from their inception to March 2018. STUDY SELECTION: Randomized controlled trials investigating the effects of tai chi on individuals with type 2 diabetes mellitus were eligible. DATA EXTRACTION: Biomedical outcomes (fasting plasma glucose, glycosylated haemoglobin (HbA1c), fasting insulin, insulin resistance, body mass index, total cholesterol, blood pressure) as well as balance and quality of life-related outcomes were extracted independently by 2 reviewers. Stata 12.0 software was used to synthesize data if there was no or moderate heterogeneity across studies. Otherwise, narrative summaries were performed. DATA SYNTHESIS: A total of 23 studies (25 articles) involving 1,235 patients were included in this meta-analysis. Significant changes in tai chi-related effects were observed in lowering fasting plasma glucose (standardized mean difference; SMD -0.67; 95% confidence interval (95% CI) -0.87 to -0.47; p <0.001), HbA1c (mean difference; MD-0.88%; 95% CI -1.45% to -0.31%; p =0.002) and insulin resistance (MD -0.41; 95% CI -0.78 to -0.04; p = 0.029). Beneficial effects of tai chi were also found in decreasing body mass index (MD -0.82 kg/m2; 95% CI -1.28 to -0.37 kg/m2; p < 0.001) and total cholesterol (SMD -0.59; 95% CI -0.90 to -0.27; p < 0.001). In addition, tai chi reduced blood pressure (systolic blood pressure (MD -10.03 mmHg; 95% CI -15.78 to -4.29 mmHg; p = 0.001), diastolic blood pressure (MD -4.85 mmHg; 95% CI -8.23 to -1.47 mmHg; p = 0.005)) and improved quality of life-related outcomes (physical function (MD 7.07; 95% CI 0.79-13.35; p = 0.027), bodily pain (MD 4.30; 95% CI 0.83-7.77; p = 0.015) and social function (MD 13.84; 95% CI 6.22-21.47; p < 0.001)). However, no impact was exerted on fasting insulin (SMD -0.32; 95% CI -0.71 to 0.07; p = 0.110) or balance (MD 2.71 s; 95% CI -3.29 to 8.71 s; p = 0.376). CONCLUSION: Tai chi is effective in controlling biomedical outcomes and improving quality of life-related outcomes in individuals with type 2 diabetes mellitus, although no effects were observed on balance and fasting insulin. Further high-quality research is needed to elucidate the effects of different types of tai chi, the long-term effects of tai chi, the impact on respiratory function, and the association between tai chi and the risk of developing type 2 diabetes mellitus in healthy individuals.

RESUMO

Child development and wellness are strictly dependent on several factors among them physical activity, a proper nutrition and, of critical importance, a healthy mind. Psychopathologies like attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD) and conduct disorder (CD) have a direct negative impact on social, academic or occupational functioning of the affected children. If left untreated, these pathologies may progress to adulthood, thus requiring research strategies on conventional and nonconventional modalities of treatment. In this pilot study, conducted during the academic year 2015/2016, a combination of exercises of TaijiQuan (TJQ) and Qi Gong (QG) were taught to four selected children, three males and one female, aged between 6 and 10, suffering from the above mentioned behavioural disorders. The main goal was to understand if it is possible to achieve any kind of improvement in their condition, by evaluating the scores of the Achenbach Teacher's Report Form (TRF) in the beginning and ending of the experimental period. Results showed very interesting improvements in symptoms of CD, ODD and ADHD-HI (hyperactive-impulsive), while ADHD-PI (predominantly inattentive) showed only minor improvements. The overall symptom improvement was 43% across pathologies, which demonstrates that TJQ and QG may be a promising treatment of symptoms for children with behavioural disorders. More research is needed with controlled experimental designs and statistically representative samples in order to fully comprehend the versatility of these modalities.

RESUMO

This study examines altered resting state functional connectivity (rsFC) of the cognitive control network (CCN) in fibromyalgia patients as compared to healthy controls, as well as how an effective mind-body intervention, Tai Chi, can modulate the altered rsFC of the CCN. Patients with fibromyalgia and matched healthy subjects were recruited in this study. Fibromyalgia patients were scanned 12 weeks before and after intervention. The bilateral dorsolateral prefrontal cortex (DLPFC) was used as a seed to explore the rsFC of the CCN. Data analysis was conducted with 21 patients and 20 healthy subjects. Compared to healthy subjects, fibromyalgia patients exhibited increased rsFC between the DLPFC and the bilateral rostral anterior cingulate cortex (rACC) and medial prefrontal cortex (MPFC) at baseline. The rsFC between the CCN and rACC/MPFC further increased after Tai Chi intervention, and this increase was accompanied by clinical improvements. This rsFC change was also significantly associated with corresponding changes in the Overall Impact domain of the Revised Fibromyalgia Impact Questionnaire (FIQR). Further analysis showed that the rACC/MPFC rsFC with both the PAG and hippocampus significantly decreased following Tai Chi intervention. Our study suggests that fibromyalgia is associated with altered CCN rsFC and that effective mind-body treatment may elicit clinical improvements by further increasing this altered rsFC. Elucidating this mechanism of enhancing the allostasis process will deepen our understanding of the mechanisms underlying mind-body interventions in fibromyalgia patients and facilitate the development of new pain management methods.

RESUMO

This study aims to investigate the effects of Tai Chi Chuan (TCC) and brisk walking (BW) on balance and training duration for the two exercises to significantly improve balance. A total of 48 elderly women were randomly divided into three groups. The TCC and BW groups completed a 60-min intervention training program with five sessions weekly for 16 weeks. Single-leg standing balance was tested every 4 weeks. Results showed that all the variables with eyes open improved on the eighth week (p < .05) in the TCC group and on the 12th week (p < .01) in the BW group. All variables with eyes closed improved on the 12th week (p < .01) in the TCC group and on the 16th week (p < .05) in the BW group. The results showed that 12 and 16 weeks of TCC and BW, respectively were essential to improve balance with eyes closed among the women aged 60-70 years.

RESUMO

PURPOSE: To evaluate the feasibility of Tai Chi (TC) and electronic tablet (ET) interventions on older adults' cognition and health and to explore participants' perceptions of intervention activities. DESIGN: An emergent embedded experimental mixed methods design was used in which the qualitative strand helped explain intervention results. METHOD: Older adults who participate in TC classes will have improved cognition and health compared with older adults who participate in ET classes. Twenty-six participants from two assisted living residences were recruited and randomized to receive nine TC or ET classes. The Modified Mini Mental State Exam was used to measure cognition and the SF-12v2 assessed perceived health before and after the intervention. Participants were invited to share perceptions of the two interventions. Institutional review board approval was obtained and participants provided signed consent for both quantitative and qualitative strands. FINDINGS: There was no significant difference within or between groups on cognition and health scores. CONCLUSIONS: TC and ET use are activities that can be delivered in the community and have the potential to promote compensatory scaffolding as described by the revised scaffolding theory of aging and cognition. Future research should involve larger samples and teaching methods that promote learning postures.

RESUMO

PURPOSE: To contribute to the treatment fidelity literature by providing real-world examples and suggestion for future research and potential clinical application, this article reports on implementation, assessment, and evaluation of treatment fidelity in mind-body self-care approaches in at-risk women. METHOD: Aligning with best practices, treatment fidelity was integrated into three randomized clinical trials. The first examined the effects of a tai chi intervention designed to decrease cardiometabolic risk factors in women; the second examined the effects of a tailored guided imagery intervention on pregnancy outcomes in African American women; and the third explored effects of a mindful physical activity intervention (yoga) on psychological outcomes in women with moderate to severe depressive symptoms. FINDINGS: Each of the studies successfully designed, implemented, and evaluated strategies to address recommended treatment fidelity components. These strategies provided qualitative and quantitative data that informed intervention refinement, directions for future research, and application in clinical practice. CONCLUSIONS: The treatment fidelity framework used here is based on best practices and was a feasible and reliable approach for ensuring and reporting on treatment fidelity, which is contributing to future research to foster translation of potentially effective mind-body self-care approaches into practice.

RESUMO

BACKGROUND Tai Chi is an ancient form of physical activity that has been shown to improve cardiovascular function, but to date there had been no comprehensive systematic review on the effect of Tai Chi exercise on balance function of patients with stroke. This study evaluated the effect of Tai Chi exercise on balance function in stroke patients. MATERIAL AND METHODS PubMed, Cochrane library, and China National Knowledge Information databases and the Wan Fang medical network were searched to collect the articles. The random-effects model was used to assess the effect of Tai Chi exercise on balance function of stroke patients. RESULTS Six studies were chosen to perform the meta-analysis according to the inclusion and exclusion criteria. There were significant improvements of balance on Berg Balance Scale score (MD=4.823, 95% CI: 2.138-7.508), the standing balance with fall rates (RR=0.300, 95%CI: 0.120-0.770), functional reach test and dynamic gait index in Tai Chi intervention group compared to the control intervention group. However, the short physical performance battery for balance (SPBB) showed Tai Chi did not significantly improve the ability of balance for stroke patients (MD=0.293, 95%CI: -0.099~0.685). CONCLUSIONS Tai Chi exercise might have a significant impact in improving balance efficiency by increasing BBS score and reducing fall rate.

RESUMO

BACKGROUND: Tai Chi (TC) is a Chinese mind-body exercise with proven physical and psychological benefits. A modified TC via virtual reality (VR) may be suitable for the elderly owing to the immediate guidance and feedback regarding movement accuracy. This study explored the cognitive and physical effects of a VR-based TC (VRTC) exercise program on older adults with cognitive impairment (CI). METHODS: Sixty older adults with CI were cluster-assigned to either the VRTC or the control group; the intervention was conducted twice weekly for 6 months. Outcomes included cognitive and physical functions. The movement accuracy score and attendance were recorded. Generalized estimating equation (GEE) and multiple regression analyses were performed. RESULTS: Adjusted GEE analysis showed significant interaction effects in the 6-min walk test, 30-s sit-to-stand test, functional reach, 5-m gait speed, and abstract thinking and judgment. Overall, medium to large effect sizes (d = 0.50-0.82) were found in favor of the VRTC group. The average movement accuracy score in the first 3 months significantly predicted improvement in cognitive performance (p = 0.011). CONCLUSIONS: The VRTC exercise posed a protective effect for some cognitive and physical functions in older adults with CI. The more engaging the program, the greater the improvement in the cognitive performance.

RESUMO

BACKGROUND: Falls are a public health issue for the older adult population and more so for people with dementia (PWD). Compared with their cognitively intact peers, PWD are at higher risk of falls and injurious falls. This randomised controlled trial aims to test the clinical and cost effectiveness of Tai Chi to improve postural balance among community-dwelling PWD and to assess the feasibility of conducting a larger definitive trial to reduce the incidence of falls among PWD. METHODS: A 3-centre parallel group randomised controlled trial with embedded process evaluation. One hundred and fifty community-dwelling dyads of a person with dementia and their informal carer will be recruited and assessed at baseline and at six-month follow-up. Dyads will be randomised in a 1:1 ratio to either usual care or usual care plus a Tai Chi intervention for 20 weeks. The Tai Chi intervention will consist of weekly classes (45 min' Tai Chi plus up to 45 min for informal discussion, with up to 10 dyads per class) and home-based exercises (20 min per day to be facilitated by the carer). Home practice of Tai Chi will be supported by the use of behaviour change techniques with the Tai Chi instructor at a home visit in week 3-4 of the intervention (action planning, coping planning, self-monitoring, and alarm clock reminder) and at the end of each class (feedback on home practice). The primary outcome is dynamic balance measured using the Timed Up and Go test, coinciding with the end of the 20-week intervention phase for participants in the Tai Chi arm. Secondary outcomes for PWD include functional balance, static balance, fear of falling, global cognitive functioning, visual-spatial cognitive functioning, quality of life, and falls. Secondary outcomes for carers include dynamic balance, static balance, quality of life, costs, and carer burden. DISCUSSION: This trial is the first in the UK to test the effectiveness of Tai Chi to improve balance among PWD. The trial will inform a future study that will be the first in the world to use Tai Chi in a trial to prevent falls among PWD. TRIAL REGISTRATION: NCT02864056 .

RESUMO

BACKGROUND: Traditional Tai Chi is too complex for most elderly individuals. There have been few reports regarding the development of simplified Tai Chi programs to suit the physical needs of elderly adults. However, these programs were not individualized according to the participants' balance control abilities. OBJECTIVE: Purpose of this study is to develop an individualized Tai Chi program and report the feasibility of the program. METHODS: Phase 1: Five Tai Chi masters performed the Tai Chi movements on a force platform. Based on the results of center of pressure displacement and the individual's balance abilities, an individualized program was developed.Phase 2: Ten community-dwelling older adults received 24 half-hour-sessions, using the individualized Tai Chi exercise program. The Berg Balance Scale (BBS) score, Timed Up & Go (TUG) test, forward reach, and strength of the knee extensor were determined before and after intervention. RESULTS: Participants achieved improved performance on balance control as measured with BBS (p≤0.001), TUG (p = 0.004) and forward reach (p = 0.035) as well as knee extensor strength (p = 0.002) after the program. CONCLUSIONS: This preliminary result suggests that the individualized Tai Chi program is potentially effective to improve balance function and knee extensor strength of the elderly.

RESUMO

BACKGROUND AND AIM: Physical activity can improve the mental and physical functioning of older people. This study investigated the impact of Tai Chi exercise on the quality of life of older men. METHODS: This randomized controlled clinical trial was conducted on 132 older men in an urban area of Iran. The subjects were randomly assigned into two groups: a Tai Chi intervention group and a control group (n = 66 per group). Quality of life was evaluated using the Leiden-Padua quality of life questionnaire before and after the intervention. Data analysis was performed using analytical statistics via the SPSS software. RESULTS: After eight weeks of Tai Chi exercise, the mean scores of quality of life in different areas demonstrated a statistically significant difference between the two groups (p < 0 0.05). CONCLUSION: This study illustrated that the 8-week Tai Chi intervention had a positive effect on quality of life in older men.
