RESUMO

BACKGROUND: The aim of the study is to compare a 16-week tai chi and Iyengar yoga program effects on muscle strength, static and dynamic balance, and balance confidence in elderly people. METHODS: A total of 48 participants (≥60 years old) without mobility-impairing neurological disease, dementia, cardiovascular disease/symptoms during moderate exercise, poorly controlled hypertension, or balance-impairing drug use. Participants were divided into a tai chi group, an Iyengar yoga group, and a control group (eight males and eight females per group), using a restricted randomization scheme generated by software. While the former two undertook 16-week exercise programs, the control group received general education. Maximum concentric strength was measured with an isokinetic dynamometer. The one-legged stand with eyes closed, "8 feet up and go," and Activities-specific Balance Confidence (ABC) scale were used to assess static balance, dynamic balance, and balance confidence in daily activities, respectively. RESULTS: Both programs improved all measures significantly with tai chi being more effective for increasing knee flexor strength (P=0.045) and extensor strength (P=0.032) and ABC score (P=0.034); Iyengar yoga was more effective for improving static balance (P=0.014) and dynamic balance (P=0.025; all P values here vs. the other program). CONCLUSIONS: Tai chi and Iyengar yoga can improve strength, balance, and balance confidence among older people. Both are suitable exercise choices for older adults.

RESUMO

BACKGROUND: Stroke is the leading cause of death worldwide. China faces a similar risk of stroke as developed countries because of considerable changes in lifestyle, such as overeating and smoking. Tai Chi is a traditional form of mind-body exercise that has been widely practiced in China for thousands of years. However, there are few studies on the effect of Tai Chi on the cardiopulmonary function of stroke patients in the recovery phase. Therefore, it is necessary to observe the effect of Tai Chi on the cardiorespiratory fitness of patients after stroke. METHODS: This is a parallel-design, two-arm, analyst assessor-blinded, randomized controlled trial. A total of 226 stroke patients in the recovery phase will be recruited and assigned randomly to a control group or Tai Chi group at a 1:1 ratio. The patients in the Tai Chi group will perform the Tai Chi exercise. The patients in the control group will perform walking exercises. Patients in both groups will receive conventional treatments and healthy education. The primary outcomes will be VO2peak and scores on the MOS item short form health survey (SF-36) scale. Secondary outcomes will include vital capacity (VC), ejection fractions (EF), and cardiac output (CO). The assessments of the tests will be performed at three time points (before exercise, at the end of exercise, and 6 weeks after exercise). Adverse events will be recorded faithfully during the study. DISCUSSION: If the results are positive, this study will contribute to the establishment of further guided Tai Chi rehabilitation programs. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR2000034719 . Registered on 16 July 2020.

RESUMO

This study examined the biomechanics of the lower limbs during four typical Tai Chi (TC) movements: wave hand in cloud, leaning fly side, repulse monkey, and brush knee and twist step, in order to provide biomechanical evidence-based recommendations for patients with knee osteoarthritis (OA) practicing TC. Joint angles and joint moments of the hip, knee, and ankle in frontal and sagittal plane as well as ground reaction forces were examined while performing TC and regular walking in an experienced 38 years old TC master. The results showed that relative to walking, the four TC movements are characterized by a wide motion range of lower limbs, slow increase in joint loading, and strong muscle activity during performance. Therefore, these TC movements could be suitable for patients with knee OA to practice for improving the muscle strength of their lower limbs and functional ability.

RESUMO

BACKGROUND: A majority of lung cancer patients are diagnosed at advanced stages. Although there is considerable evidence of the benefits of aerobic exercise and tai-chi for lung cancer patients, little is known about the comparative effectiveness of the 2 exercise modes in advanced lung cancer patients. OBJECTIVES: To explore the feasibility and preliminary effects of aerobic exercise and tai-chi interventions on survival and well-being among advanced lung cancer patients. METHODS: In an assessor-blinded, exploratory randomized controlled trial, 30 advanced lung cancer patients were randomized to an aerobic exercise group, a tai-chi group (both attending 12-week, twice-weekly supervised sessions), or a self-management control group (receiving written exercise guidelines). The primary outcomes focused on feasibility including intervention completion, exercise adherence, and adverse events, while the secondary outcomes addressed preliminary effects and included 1-year survival, cancer symptoms (Pittsburgh Sleep Quality Index, Hospital Anxiety and Depression Score, Brief Fatigue Inventory), quality of life (EORTC QLQ-C30, QLQ-LC13), physical performance (6-minute walk test, up-and-go, sit-to-stand, 1-leg standing), activity levels (actigraph), and circadian rhythms (salivary cortisol). RESULTS: Intervention feasibility was established with a satisfactory completion rate at post-intervention for the aerobic exercise group (80%) and the tai-chi group (78%). The tai-chi group attained higher adherence than the exercise group in terms of attendance in supervised sessions (89% vs 75% of scheduled classes) and self-practice (225% vs 87% of the prescribed amount). Higher adherence to self-practice in the tai-chi group remained at the 6-month follow-up (81% vs 38% of the prescribed amount). No adverse event as a result of the intervention was reported. Effect-related outcomes did not show statistically significant changes in any group, except an improvement post-intervention in the up-and-go (-2.26, 95% CI: -4.04, -0.48) and sit-to-stand tests (4.52, 95% CI: 2.19, 6.85) in the aerobic exercise group. CONCLUSIONS: The findings support the feasibility of aerobic exercise and tai-chi interventions in advanced lung cancer patients. A future study with a larger sample from multiple sites is recommended to confirm the comparative effects of the 2 exercise interventions relative to the self-management group and to enhance the generalizability of the findings.

RESUMO

The public space of a park is one of the most important carriers of social interaction and cultural practice in urban areas. Taking an ethnography of Taijiquan in Chengdu (China) as a case study, this article explores the production of Taijiquan's "park culture space" (PCS). Our analysis revealed that the development of PCS not only transformed "public space" in the park to a "private space" through Taijiquan practice and exchange but also transformed "material space" in the park into "social space" with identification. We found that working on the process of self-managing Taijiquan's "park culture space" included the democratic operation mechanism of communication and consultation, the cooperative operation mechanism of mutual benefit, and the incentive operation mechanism of balancing interests. Taijiquan's "park culture space" was the reproduction of public space that was not only bonded with Taijiquan practice but was also reconstructed and expanded by Taijiquan practitioners. Furthermore, it involved the return of Taijiquan practitioners' historical memory and collective life experience alongside the construction of Taijiquan practitioners' group identity and the development of self-organization.

RESUMO

Since multispectral images (MSIs) and RGB images (RGBs) have significantly different definitions and severely imbalanced information entropies, the spectrum transformation between them, especially reconstructing MSIs from RGBs, is a big challenge. We propose a new approach, the Taiji Generative Neural Network (TaijiGNN), to address the above-mentioned problems. TaijiGNN consists of two generators, G_MSI, and G_RGB. These two generators establish two cycles by connecting one generator's output with the other's input. One cycle translates the RGBs into the MSIs and converts the MSIs back to the RGBs. The other cycle does the reverse. The cycles can turn the problem of comparing two different domain images into comparing the same domain images. In the same domain, there are neither different domain definition problems nor severely underconstrained challenges, such as reconstructing MSIs from RGBs. Moreover, according to several investigations and validations, we effectively designed a multilayer perceptron neural network (MLP) to substitute the convolutional neural network (CNN) when implementing the generators to make them simple and high performance. Furthermore, we cut off the two traditional CycleGAN's identity losses to fit the spectral image translation. We also added two consistent losses of comparing paired images to improve the two generators' training effectiveness. In addition, during the training process, similar to the ancient Chinese philosophy Taiji's polarity Yang and polarity Yin, the two generators update their neural network parameters by interacting with and complementing each other until they all converge and the system reaches a dynamic balance. Furthermore, several qualitative and quantitative experiments were conducted on the two classical datasets, CAVE and ICVL, to evaluate the performance of our proposed approach. Promising results were obtained with a well-designed simplistic MLP requiring a minimal amount of training data. Specifically, in the CAVE dataset, to achieve comparable state-of-the-art results, we only need half of the dataset for training; for the ICVL dataset, we used only one-fifth of the dataset to train the model, but obtained state-of-the-art results.

RESUMO

Contributing to Taijiquan studies, this research uses spatial analysis tools in ArcGIS 10.3 and SPSS 23.0 to map out the spatial distributional pattern of the Taijiquan organizations in London, and then explores factors attributing to the spatial distribution of Taijiquan culture. The result shows that the distribution of Taijiquan organizations in London generally presents a spatial distribution structure of "dense center + sparse periphery"; the spatial distribution is unbalanced, showing a cohesive distribution; the directional distribution tends to be obvious in areas that are proximate to urban traffic arteries and afforestation in London. Through multivariate hierarchical regression analysis, the study explores the influential factors for the spatial distribution of Taijiquan organizations in London. The results show that: population size, economic level, and education level have little influence on the spatial distribution of Taijiquan organizations; however, the population density of people over 65 years old, the accessibility of public service facilities such as green spaces, and public urban traffic has a significant impact on the spatial distribution of Taijiquan organizations.

RESUMO

INTRODUCTION: The fatigue-sleep disturbance-depression symptom cluster (FSDSC) is one of the most common and debilitating side effects in patients with breast cancer (BC) throughout their treatment trajectory. Tai chi has been supported as a promising non-pharmacological intervention for the individual symptom relief of cancer-related fatigue, sleep disturbance and depression. However, relevant evidence of using tai chi for FSDSC management in patients with BC has been lacking. METHODS: This study will be a two-arm, single-blinded pilot randomised controlled trial involving an 8-week intervention and a 4-week follow-up. Seventy-two patients with BC experiencing the FSDSC will be recruited from two tertiary medical centres in China. The participants will be randomised to either a tai chi group (n=36) or a control group (n=36). The participants in the tai chi group will receive an 8-week tai chi intervention in addition to standard care, while the participants in the control group will receive standard care only consisting of a booklet on the self-management of cancer symptoms. The primary outcomes will include a series of feasibility assessments of the study protocol in relation to the study's methodological procedures, including subject recruitment and follow-up process, completion of study questionnaires and the feasibility, acceptability and safety of the intervention. The secondary outcomes will be the clinical outcomes regarding the effects of tai chi on the FSDSC and quality of life, which will be evaluated by the Brief Fatigue Inventory, the Pittsburgh Sleep Quality Index, the Hospital Anxiety and Depression Scale and the Functional Assessment of Cancer Therapy-Breast questionnaires. ETHICS AND DISSEMINATION: Ethics approval was obtained from relevant sites (H19094, KY2019133, 201932). The findings of the study will be published in peer-reviewed scientific journals and at conferences. TRAIL REGISTRATION NUMBER: NCT04190342; Pre-results.

RESUMO

BACKGROUND: Degenerative osteoarthritis (OA) often leads to pain and stiffness of the affected joints, which may affect the physical performance and decrease the quality of life of people with degenerative knee OA. Compared to traditional exercise, tai chi is a safe exercise with slow movements which can facilitate physical functioning and psychological well being, and might be suitable for improving the physical activities of older adults with knee OA. Therefore, this study investigated the impacts of tai chi exercise on the functional fitness of community-dwelling older adults with degenerative knee OA. METHODS: Sixty-eight community-dwelling older adults with knee OA were recruited from the local community to participate in this randomized controlled clinical trial. All subjects were randomly assigned to either an TCE group that practiced tai chi exercise (TCE) (n = 36) or a control group (CON) (n = 32) that received regular health education programs twice per week for 12 weeks. Outcome measurements were determined using functional fitness tests before and after the intervention, including a 30-s chair stand (number of repeats), 30-s arm-curl (number of repeats), 2-min step (number of steps), chair sit-and-reach (reaching distance, cm), back-scratch flexibility (distance between hands, cm), single-leg stand (time, s), functional reach (reaching distance, cm), 8-foot up-and-go (time, s), and 10-m walk tests (time, s). Pre-post comparisons of functional fitness were analyzed using the ANCOVA test with SPSS software version 18.0. RESULTS: Results revealed that participants' functional fitness in the TCE group had significantly higher adjusted mean post-tests scores than that in the CON group after the intervention, including the 8-foot up-and-go (s) (mean difference [MD]=-2.92 [-3.93, -1.91], p = 2.39*10- 7), 30-s arm curl (MD = 4.75 (2.76, 6.73), p = 1.11*10- 5), 2-min step (MD = 36.94 [23.53, 50.36], p = 7.08*10- 7), 30-s chair stand (MD = 4.66 [2.97, 6.36], p = 6.96*10- 7), functional-reach (MD = 5.86 [3.52, 8.20], p = 4.72*10- 6), single-leg stand with eyes closed (MD = 3.44 [1.92, 4.97], p = 2.74*10- 5), chair sit-and-reach (MD = 3.93 [1.72, 6.15], p = 0.001), and single-leg stand with eyes opened (MD = 17.07 [6.29, 27.85], p = 0.002), with large effect sizes (η²=0.14 ~ 0.34). CONCLUSIONS: Community-dwelling older adults with knee OA in the TCE group had better functional fitness performances after the 12-week tai chi intervention than those receiving only health education.

RESUMO

BACKGROUND: Previous studies have reported that C reactive protein (CRP), tumor necrosis factor-alpha (TNF-alpha), and interleukin-6 (IL-6) in Coronavirus disease 2019 (COVID-19) patients are significantly increased, and their progressive increases are clinical warning indicators of severe and critical severity. The purpose of this meta-analysis is to evaluate the efficacy of Tai Chi on CRP, TNF-alpha and IL-6, and provide a basis for complementary treatment of COVID-19. METHODS: Five English databases (PubMed, Web of Science, Physiotherapy Evidence Database, Cochrane Library and Embase) and four Chinese electronic databases (CNKI, Wanfang, China Science and Technology Journal Database and SinoMed) were searched from inception to April 1st, 2020. Combination MeSH and free text terms were used to make up search strategy. Interventions in RCTs were Tai Chi with or without comparison (usual care, health education, drug therapy, psychosocial therapy). Revman version 5.3 was used to analyze the extracted data. Continuous outcomes were described by SMD, and the I2 test was used to assess heterogeneity. Revised Physiotherapy Evidence Database scale was used to assess methodological quality. RESULTS: Nine RCTs involving 571 participants met the inclusion criteria, and the sample size ranged from 19 to 100 per study. Tai Chi can significantly reduce TNF-alpha (Tai Chi intervention: SMD =-0.92, 95% CI: -1.32 to -0.53; Tai Chi plus drug treatment intervention: SMD =-0.63, 95% CI: -1.15 to -0.11), moreover, it could reduce the amount of IL-6 (Tai Chi intervention: SMD =-0.62, 95% CI: -1.00 to -0.23; Tai Chi plus drug treatment intervention: SMD =-2.17, 95% CI: -3.69 to -0.64) and CRP (Tai Chi plus drug treatment intervention: SMD =-1.98, 95% CI: -2.47 to -1.50) while with a high exercise amount. A low exercise amount of Tai Chi showed poor efficacy on CRP (Tai Chi intervention: SMD =-0.18, 95% CI: -0.61 to 0.25; Tai Chi plus drug treatment intervention: SMD =-0.15, 95% CI: -0.47 to 0.16) and IL-6 (Tai Chi intervention: SMD =0.15, 95% CI: -0.24 to 0.55). DISCUSSION: The strength of evidence might be limited due to relatively low methodological quality, heterogeneity and indirectness. The overall results elucidate that Tai Chi could significantly reduce TNF-alpha while it did not show the same effects in IL-6 and CRP. After subgroup analysis, Tai Chi with a high exercise amount can reduce IL-6 and CRP. Tai Chi with a high exercise amount could be suggested as a complementary intervention for people with COVID-19. TRIAL REGISTRATION: PROSPERO CRD42020177655.

RESUMO

While studies on the health benefits of Tai Chi have sprung up over the past four decades, few have engaged in collecting global data, estimating the developing trends, and conducting reviews from the perspective of visualization and bibliometric analysis. This study aimed to provide a summary of the global scientific outputs on Tai Chi research from 1980 to 2020, explore the frontiers, identify cooperation networks, track research trends and highlight emerging hotspots. Relevant publications were downloaded from the Web of Science Core Collection (WoSCC) database between 1980 and 2020. Bibliometric visualization and comparative analysis of authors, cited authors, journals, co-cited journals, institutions, countries, references, and keywords were systematically conducted using CiteSpace software. A total of 1078 publications satisfied the search criteria, and the trend of annual related publications was generally in an upward trend, although with some fluctuations. China (503) and Harvard University (74) were the most prolific country and institution, respectively. Most of the related researches were published in the journals with a focus on sport sciences, alternative medicine, geriatrics gerontology, and rehabilitation. Our results indicated that the current concerns and difficulties of Tai Chi research are "Intervention method", "Targeted therapy", "Applicable population", "Risk factors", and "Research quality". The frontiers and promising domains of Tai Chi exercise in the health science field are preventions and rehabilitations of "Fall risk", "Cardiorespiratory related disease", "Stroke", "Parkinson's disease", and "Depression", which should receive more attention in the future.

RESUMO

OBJECTIVES: This systematic review evaluated the effects of Tai Chi on health outcomes among community-dwelling adults with or at risk of metabolic syndrome (MetS). METHODS: Randomized controlled trials (RCTs) were searched in 10 databases. Data were statistically pooled for meta-analysis. RESULTS: Twenty RCTs were included. One study involved adults with MetS, and the other 19 studies involved adults with at least one risk factor for MetS. Tai Chi was found to reduce waist circumference and increase high-density lipoprotein cholesterol in obese adults. Tai Chi also reduces waist circumference, body mass index, blood glucose level, insulin resistance, and increases the quality of life (QoL) in adults with elevated blood glucose/type 2 diabetes (T2DM). Among participants with hypertension, Tai Chi improves blood pressure, lipid profiles, anxiety, depression, and physical QoL. CONCLUSIONS: Tai Chi may be effective for enhancing the physiological and psychosocial wellbeing of community-dwelling adults at risk of MetS. Further RCTs are needed to examine its effects in adults with MetS and identify optimal regimes.

RESUMO

The ongoing coronavirus 2019 (COVID-19) pandemic has posed a significant threat to both people's physical and mental health. Physical inactivity, sedentary behavior, and negative emotions among the general population have been significantly increased because of COVID-19 home confinement. These are major risk factors associated with higher incidences of morbidity and mortality. Therefore, effective exercise management should be proposed as a prevention strategy to improve both physical and mental health while diminishing the effects of COVID-19. Tai Chi as a low-to-moderate aerobic exercise combines physical and mental training and plays a positive impact on human health. Here we aim to outline the effects of Tai Chi on the immune system, inflammatory responses, pulmonary function, and emotional control. The benefits of Tai Chi practice for individuals coping with COVID-19 are stated here which include immune system promotion, inflammation response reduction, rehabilitation in respiratory diseases, and emotional improvement. This statement has been supported by available clinical, physiological, and biological research. As a result, we hope to introduce Tai Chi as an effective exercise intervention for people coping with COVID-19 and as a beneficial exercise for maintaining an active lifestyle during a pandemic.

RESUMO

Stroke survivors suffer from disease-associated symptoms. Tai Chi can be a beneficial approach to provide an adapted form of intervention to manage their symptoms. The study aimed to determine the effects of a Tai Chi-based stroke rehabilitation program on symptom clusters, physical and cognitive functions, and stroke-specific quality of life among stroke survivors in Korea. Thirty-four stroke survivors were randomly assigned to receive either the Tai Chi-based program or the stroke-symptom management program. The feasibility of the program and its effects on the outcomes were assessed at baseline, 3 months, and 6 months. Repeated measures ANOVA showed that most symptoms improved in both groups during the 6-month period, but swallowing-related symptoms improved significantly in the Tai Chi group. Based on the interaction effect, Tai Chi was more effective on flexor muscle strength, ambulation, and activities of daily living and cognitive function over 6 months than their counterparts. Among SS-QOL dimensions, the Tai Chi group showed significant improvements in the thinking and self-care dimensions. The Tai Chi-based stroke rehabilitation program was feasible and safely applicable to stroke survivors in the community settings. This program could improve symptoms, physical and cognitive function, leading to improvements in the self-care dimension of the SS-QOL among stroke survivors.

RESUMO

In our randomized controlled trial, we investigated whether Wu-style Tai Chi (Tai Chi combined with Daoyin) as a potential exercise prescription is more effective than simplified Tai Chi in the prevention and treatment of hypertension and hyperlipidemia in the middle-aged and elderly. We randomly assigned 66 patients with hypertension and hyperlipidemia to one of the two groups: the Wu-style Tai Chi group or the simplified Tai Chi group; the simplified Tai Chi group only exercised simplified Tai Chi three times a week for 6 weeks. The Wu-style Tai Chi group participated in 60 min of Wu-style Tai Chi three times a week for 6 weeks. Serum biochemical tests were conducted at baseline and at the end of the study. Measurements of blood pressure were performed at the same time. Primary outcomes were compared within and between groups at baseline and at 6 weeks. The participants in the Wu-style Tai Chi group performed, at 6 weeks, significantly better than baseline on all of the primary outcomes (p value ≤ 0.05). The results also show significant difference within the simplified Tai Chi group from baseline to 6 weeks in TCHO (mmol/L), SBP (mmHg), and LDL-C (mmol/L) (p value < 0.05). From baseline to 6 weeks, the Wu-style Tai Chi group had significant differences at more test indexes in serum and blood pressure than the simplified Tai Chi group. At 6 weeks, the Wu-style Tai Chi group had a significantly greater mean improvement in the SBP (mmHg) than did the simplified Tai Chi group (mean between-group difference, -5.80 (mmHg) [95% CI, -14.01 to 2.41]; p = 0.007). The results showed that, compared with simplified Tai Chi, Wu-style Tai Chi had a better effect on hypertension in the middle-aged and elderly. At 6 weeks in LDL-C (mmol/L), the Wu-style Tai Chi group had significantly greater improvement between the two groups (means between-group difference, -0.45 (mmol/L) [95% CI, -0.89 to -0.17]; p = 0.03). The results showed that Wu-style Tai Chi protected the cardiovascular system of the middle-aged and elderly in improving LDL-C (mmol/L), and was more significant than simplified Tai Chi. After 6 weeks of exercise, Wu-style Tai Chi could effectively improve hyperlipidemia and hypertension. The total effective rate of cardiovascular disease was 90.00%. There was significant difference in the treatment effect of hypertension and hyperlipidemia between the two groups during 6 weeks (p = 0.039), showing that, in a small population of middle-aged and elderly subjects, Wu style Tai Chi could be useful in managing important CV risk factors, such as hypertension and hyperlipidemia.

RESUMO

Purpose: This study evaluates the feasibility of delivering a virtual (online) falls prevention intervention for older adults with mild cognitive impairment (MCI). Methods: Community-dwelling older adults with MCI (mean age = 76.2 years, 72% women) were randomized to either a Tai Ji Quan (n = 15) or stretching group (n = 15) and participated in 60-minute virtual exercise sessions, via Zoom, twice weekly for 24 weeks. The primary outcome was the incidence of falls. Secondary outcomes were the number of fallers and changes from baseline in the 4-Stage Balance Test, 30-second chair stands, and Timed Up and Go Test under both single- and dual-task conditions. Results: The intervention was implemented with good fidelity, an overall attendance rate of 79%, and 13% attrition. Compared with stretching, Tai Ji Quan did not reduce falls (incidence rate ratio = 0.58; 95% confidence interval [CI], 0.32 to 1.03) or the number of fallers (relative risk ratio = 0.75; 95% CI, 0.46 to 1.22) at week 24. The Tai Ji Quan group, however, performed consistently better than the stretching group in balance (between-group difference in change from baseline, 0.68 points; 95% CI, 0.12 to 1.24), 30-second chair stands (1.87 stands; 95% CI, 1.15 to 2.58), and Timed Up and Go under single-task (-1.15 seconds; 95% CI, -1.85 to -0.44) and dual-task (-2.35; 95% CI, -3.06 to -1.64) conditions. No serious intervention-related adverse events were observed. Conclusion: Findings from this study suggest the feasibility, with respect to intervention fidelity, compliance, and potential efficacy, of implementing an at-home, virtual, interactive Tai Ji Quan program, delivered in real-time, as a potential balance training and falls prevention intervention for older adults with MCI.

RESUMO

INTRODUCTION: The development and well-being of children are directly linked to several aspects. Among those aspects, physical activity, an adequate nutrition, and a healthy mind, seem to be of crucial importance. Psychopathologies, such as anxiety and depression, have a negative impact on life, especially when co-occurring (mixed-anxiety depression disorder/cothymia), and the clinical implications include a higher risk of suicide and psychiatric hospitalization, elevated disability, decreased compliance with medical treatment, and considerably increased usage of medical services. Thus, research in conventional and nonconventional modalities is necessary to address this issue. The main objective of this study was to understand if TJQ and QG could be effective as a mindfulness cognitive-behavioural based therapeutic tool with body movement, for the treatment of children suffering from cothymia. METHODS: In this small study, six selected children, four males and two females aged between 7 and 11 years old, were taught a set of exercises of TaijiQuan (TJQ) and Qi Gong (QG). To obtain the results, the Achenbach Teacher's Report Form (TRF) was applied at the beginning of the experimental period, as well as at the ending of the experimental period. The resulting scores were analysed to observe the difference between both moments of evaluation. RESULTS: Results showed some improvements in symptoms, with an average improvement of 46%. CONCLUSION: TJQ and QG seem to be a promising complementary therapeutic tool in cognitive-behavioural approaches for children who suffer from cothymia, as well as prevention and control for children who may not display symptoms at a clinical level. However, further research is needed in order to understand the full potential of these therapeutic exercises.

RESUMO

BACKGROUND: Central obesity is a major manifestation of metabolic syndrome, which is a common health problem in middle-aged and older adults. OBJECTIVE: To examine the therapeutic efficacy of tai chi for management of central obesity. DESIGN: Randomized, controlled, assessor-blinded trial. (ClinicalTrials.gov: NCT03107741). SETTING: A single research site in Hong Kong between 27 February 2016 and 28 February 2019. PARTICIPANTS: Adults aged 50 years or older with central obesity. INTERVENTION: 543 participants were randomly assigned in a 1:1:1 ratio to a control group with no exercise intervention (n = 181), conventional exercise consisting of aerobic exercise and strength training (EX group) (n = 181), and a tai chi group (TC group) (n = 181). Interventions lasted 12 weeks. MEASUREMENTS: Outcomes were assessed at baseline, week 12, and week 38. The primary outcome was waist circumference (WC). Secondary outcomes were body weight; body mass index; high-density lipoprotein cholesterol (HDL-C), triglyceride, and fasting plasma glucose levels; blood pressure; and incidence of remission of central obesity. RESULTS: The adjusted mean difference in WC from baseline to week 12 in the control group was 0.8 cm (95% CI, -4.1 to 5.7 cm). Both intervention groups showed reductions in WC relative to control (adjusted mean differences: TC group vs. control, -1.8 cm [CI, -2.3 to -1.4 cm]; P < 0.001; EX group vs. control: -1.3 cm [CI, -1.8 to -0.9 cm]; P < 0.001); both intervention groups also showed reductions in body weight (P < 0.05) and attenuation of the decrease in HDL-C level relative to the control group. The favorable changes in WC and body weight were maintained in both the TC and EX groups, whereas the beneficial effect on HDL-C was only maintained in the TC group at week 38. LIMITATIONS: High attrition and no dietary intervention. CONCLUSION: Tai chi is an effective approach to reduce WC in adults with central obesity aged 50 years or older.

RESUMO

BACKGROUND: Type 2 diabetes is an emergent worldwide health crisis, and rates are growing globally. Aerobic exercise is an essential measure for patients with diabetes, which has the advantages of flexible time and low cost. Aerobic exercise is a popular method to reduce blood glucose. Due to the lack of randomized trials to compare the effects of various aerobic exercises, it is difficult to judge the relative efficacy. Therefore, we intend to conduct a network meta-analysis to evaluate these aerobic exercises. METHODS: According to the retrieval strategies, randomized controlled trials on different aerobic exercise training will be obtained from China National Knowledge Infrastructure, WanFang, SinoMed, PubMed, Web of Science, EMBASE, and Cochrane Library, regardless of publication date or language. Studies were screened based on inclusion and exclusion criteria, and the Cochrane risk bias assessment tool will be used to evaluate the quality of the literature. The network meta-analysis will be performed in Markov Chain Monte Carlo method and carried out with Stata14 and OpenBUGS software. Ultimately, the evidentiary grade for the results will be evaluated. RESULTS: Eighteen literatures with a total of 1134 patients were included for the meta-analysis. In glycemia assessment, Tennis (standard mean difference = 3.59, credible interval 1.52, 5.65), had significantly better effects than the named control group. Tennis (standard mean difference = 3.50, credible interval 1.05, 5.59), had significantly better effects than the named Taiji group. CONCLUSION: All together, these results suggest that tennis may be the best way to improve blood glucose in patients with type 2 diabetes. This study may provide an excellent resource for future control glycemia and may also serve as a springboard for creative undertakings as yet unknown.

RESUMO

INTRODUCTION: Acute ischaemic stroke (AIS) is not only seriously damaging to the physical and mental health of patients, but also has become a major social public health problem. Effective dyskinesia rehabilitation treatment in convalescence is of great significance for AIS patients' prognosis and quality of life. Tai Chi (TC) shows great potential in improving motor function. This trial aims to evaluate the clinical efficacy of modified TC postural training (TPT), and to explore the related central-peripheral neurotransmitter mechanisms. METHODS/DESIGN: The proposed study will be a multicentre randomised controlled trial. The trial will randomise 120 eligible AIS patients in a 1:1 ratio to receive TPT or Bobath rehabilitation training. Each training session will last 40 min and will be implemented once a day and five times per week (from Monday to Friday) in a duration of 4 weeks. After finishing the 4-week treatment, another 3-month follow-up period will be seen. Root mean square generated from the surface electromyogram (sEMG) will be the primary outcome. Other sEMG time-domain parameters and frequency-domain parameters and clinical scales assessment will be the secondary outcomes. Peripheral blood samples will be collected at baseline and at the end of 4-week treatment, which will be used to explore the related therapeutic mechanisms. Intention-to-treat analysis and per-protocol analysis will both be implemented in this trial. ETHICS AND DISSEMINATION: The study has been approved by Ethics Committee of Dongzhimen Hospital Affiliated to Beijing University of Chinese Medicine, being granted approval numbers DZMEC-KY-2020-22. The research results will be disseminated through (open access) peer-reviewed publications and presentations at conferences. TRIAL REGISTRATION NUMBER: ChiCTR2000032999.
