ABSTRACT

Las enfermedades cardiovasculares están determinadas por ciertos factores de riesgos, la prevalencia y sinergia de éstos genera un de-terminado riesgo cardiovascular que deteriora la calidad de vida de quienes lo padecen. La realización de actividad física es considerada como una herramienta útil para disminuir uno de los factores de riesgo más importantes, la obesidad, medida mediante el índice de masa corporal. Sin embargo, no todos los seres humanos poseen las mismas características y capacidades físicas, por ende, la realización de ejercicio está restringida a éstas. Es en este sentido que se desarrolla el siguiente informe, el cual contempla una revisión sistemática que enfrenta a dos terapias complementarias: Yoga v/s Tai Chi, buscando la evidencia que permita la recomendación de una de ellas para la disminución de IMC en personas mayores con DM2. Los artículos fueron extraídos desde la plataforma académica PubMed, sometidos a 3 cribados de búsqueda, y criterios de inclusión y exclusión, resultando en la obtención de 4 artículos para el análisis, a partir de esta observación se obtiene que la realización de yoga es beneficiosa para la disminución de el IMC al caso índice. Por ende, se recomienda el uso de la terapia complementaria yoga, puesto que esta favorece la reducción del IMC en pacientes con enfermedades crónicas no transmisibles en comparación a la terapia complementaria Tai Chi[AU]

ABSTRACT

ObjectiveTo construct the mental health benefits of physical activity of Tai Chi and framework for college students based on International Classification of Functioning, Disability, and Health (ICF), and to systematically review the effect of physical activity of Tai Chi on anxiety, depression and sleep quality of college students. MethodsRelevant literatures about the health outcomes on anxiety, depression and sleep quality of college students participating in physical activity of Tai Chi were retrieved from databases of Web of Science, PubMed, Medline, Scopus, CNKI, Wanfang data, from the establishment to November 10th, 2022, and screened and reviewed. ResultsTen randomized controlled trials were included finally, from China and U.S., involving 960 participants (aged 16.4 to 40 years). The main sources were from journals about physical activity and health, with publication dates from 2016 to 2021. The quality of the included literatures was evaluated using the Physical Therapy Evidence Database (PEDro) scale with a mean score of 6.3. The main mental health problems of college students mainly focused on depression, anxiety, high stress, and poor sleep quality. The physical activity of Tai Chi included 24 simplified Tai Chi and Chen style Tai Chi. The frequency of physical activity of Tai Chi was mainly 1 to 6 times a week, 45 to 90 minutes (60 minutes mostly) a time, for 4 to 18 weeks. The health benefits of Tai Chi on anxiety, depression, and sleep quality for college students in the ICF were mainly in the affective function (b152), psychomotor function (b147), energy and drive function (b130), and sleep function (b134). The beneficial outcomes of physical activity of Tai Chi involved reducing anxiety, alleviating depressive symptoms and reducing stress. Compared with physical activity of Tai Chi, physical activity of Tai Chi with the addition of a twenty-four-pattern Taijiquan theory course was more effective in improving depression levels in patients with mild and moderate depression. Tai Chi also can help to improve sleep quality, shorten the time to sleep, and reduce sleep disturbances and daytime dysfunction. ConclusionA PICO framework of Tai Chi for the health benefits of college students has been constructed using ICF. Tai Chi engaged in by college students are mainly 24 simplified Tai Chi. The frequency of physical activity of Tai Chi is 45 to 90 minutes (60 minutes mostly) a time, 1 to 6 times a week, for 4 to 18 weeks. The physical activities of Tai Chi can benefit in reducing anxiety and depression of college students and improving the quality of sleep.

ABSTRACT

Lower limb osteoarthritis (OA) is a chronic, multifactorial disease characterized by impaired physical function, chronic pain, compromised psychological health and decreased social functioning. Chronic inflammation plays a critical role in the pathophysiology of OA. Tai Chi is a type of classical mind-body exercise derived from ancient Chinese martial arts. Evidence supports that Tai Chi has significant benefits for relieving lower limb OA symptoms. Using a biopsychosocial framework, this review aims to elucidate the beneficial effects of Tai Chi in lower limb OA and disentangle its potential mechanisms from the perspective of biology, psychology, and social factors. Complex biomechanical, biochemical, neurological, psychological, and social mechanisms, including strengthening of muscles, proprioception improvement, joint mechanical stress reduction, change of brain activation and sensitization, attenuation of inflammation, emotion modulation and social support, are discussed.

ABSTRACT

Resumo O Tai Chi Chuan (TCC) está entre as Práticas Integrativas e Complementares (PICS) mais utilizadas e apresenta, segundo a literatura científica, evidências clínicas para tratamento de diversos problemas de saúde. Entretanto, pouco se sabe sobre o desenvolvimento dessa modalidade no contexto do Sistema Único de Saúde (SUS). Neste sentido, o objetivo do artigo foi compreender a prática terapêutica do TCC em um serviço de referência em PICS no SUS, a partir de um estudo de caso qualitativo com observação participante e entrevistas semiestruturadas com usuários e terapeutas. Observou-se dessemelhanças entre a prática terapêutica do Tai Chi Chuan e as práticas corporais biomédicas, assim como a presença de diretrizes norteadoras de cuidado do SUS, como o acolhimento, a escuta qualificada, o vínculo terapêutico e a integralidade da atenção. Também foi identificada a prevalência de sofrimento mental como motivo de procura pela prática, necessidade de maior apoio financeiro ao serviço e resistência ao uso da Medicina Tradicional Chinesa por parte da rede de apoio de algumas usuárias.


Abstract Tai Chi Chuan (TCC) is among the most used Integrative and Complementary Health Practices (PICS) and, according to the scientific literature, presents clinical evidence for the treatment of various health problems. However, little is known about the development of this practice in the context of the Brazilian National Health System (SUS). In this sense, the objective of the article was to understand the therapeutic practice of TCC in a reference service in PICS in SUS, from a qualitative case study with participant observation and semi-structured interviews with users and therapists. Dissimilarities were observed between the therapeutic practice of TCC and biomedical body practices, as well as the presence of guidelines for SUS care, such as welcoming, qualified listening, therapeutic connection, and comprehensive care. The prevalence of mental distress was also identified as a reason for seeking the practice, as well as the need for greater financial support for the service, and the resistance to the use of Traditional Chinese Medicine by some female users' support network.

ABSTRACT

ABSTRACT Introduction: Tai chi chuan training claims to not only promote the circulation of internal energy in the body to achieve a preventive and healing effect of diseases, but also to improve static and dynamic body balance. While the former claims are not validable, the question about the effectiveness of improving balance remains valid. Objective: Verify the characteristics of lower limb balance during tai chi chuan practice. Methods: Selected volunteers underwent a bioelectricity testing system via noninvasive surface electromyography to evaluate muscle activity during the exercises. The results were collected, cataloged and statistically work on corresponding graphs according to different content of literature research for objective analysis. Results: The variation of the displacement of the center of gravity was controlled within 0.1M, the most unstable time of the center of gravity was about 0.65s before the start of balance. In temporal terms, it is found that the order of discharge of each muscle tested in the vertical balance and unilateral support was as follows: the tibialis anterior muscle discharges first, the rectus femoris and biceps femoris second, finally gastrocnemius, gluteus medius and gluteus maximus joint discharge almost at the same time. Conclusion: Some benefit is perceived in the validity of improving lateral balance velocity, shortening the action completion time, and improving balance stability, improving the quality of action in practitioners of this exercise modality. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.


RESUMO Introdução: O treinamento do tai chi chuan alega não só promover a circulação de energia interna no corpo para alcançar um efeito preventivo e curador de doenças, mas também aprimorar o equilíbrio estático e dinâmico corporal. Enquanto as primeiras afirmações não são validáveis, o questionamento sobre a eficácia no aprimoramento do equilíbrio permanece válido. Objetivo: Verificar as características do equilíbrio nos membros inferiores durante a prática do tai chi chuan. Métodos: Voluntários selecionados passaram por um sistema de testes com bioeletricidade via eletromiografia superficial não invasiva para avaliar a atividade muscular durante os exercícios. Os resultados foram coletados, catalogados e estatisticamente trabalhos sobre gráficos correspondentes, de acordo com diferentes conteúdos de pesquisa literária, para análise objetiva. Resultados: A variação do deslocamento do centro gravitacional foi controlada dentro de 0,1M, o tempo mais instável do centro de gravidade foi cerca de 0,65s antes do início do equilíbrio. Em termos temporais, constata-se que a ordem de descarga de cada músculo testado no equilíbrio vertical e apoio unilateral foi a seguinte: o músculo tibial anterior descarrega primeiro, o reto femoral e bíceps femoral em segundo lugar, finalmente conjunto gastrocnêmico, glúteos médios e glúteo máximo descarregam quase ao mesmo tempo. Conclusão: Percebe-se algum benefício na validade de aprimorar a velocidade de balanço lateral, encurtar o tempo de conclusão da ação e melhorar a estabilidade do equilíbrio, melhorando a qualidade da ação em praticantes dessa modalidade de exercício. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.

ABSTRACT

Objective:To observe any effect of Yun shou tai chi training with visual feedback on the balance of persons who have survived a stroke.Methods:Fifty-six stroke survivors were randomly divided into an observation group and a control group, each of 28. Both groups were given routine balance function training, while the observation group was additionally given Yun shou tai chi training with visual feedback. Before and after the four weeks of training, the subjects′ balance and posture were evaluated using a Nomex visual feedback balance system. Lower limb strength was evaluated with a microFET2 portable muscle strength tester. The Berg Balance Scale (BBS), Timed Up and Go Test (TUGT), 10-metre walk times (10MWTs) and the modified Barthel Index (MBI) were also applied.Results:After the training the average BBS, TUGT, 10MWT and MBI results of the observation group had improved significantly. Among the control group only TUGT times and MBI scores had improved significantly, but even then the average MBI score of the observation group was significantly higher. The training improved the strength of the trainees′ quadriceps femoris (QUA), tibialis anterior (TA) and gastrocnemius (GAS) on the hemiplegic side. Their hamstrings and GAS on the non-hemiplegic side were also significantly stronger, on average. The improvement in the QUA of the hemiplegic side in the observation group was significantly better than the control group′s average improvement. The path length (PL) and the covered area (CA) in the observation group had decreased significantly after the training, while among the controls only the CA had decreased significantly. The average PL in the observation group was therefore significantly shorter than in the control group.Conclusion:Yun shou tai chi training with visual feedback can promote the recovery of balance function after a stroke. Such training is worthy of clinical promotion and application.

ABSTRACT

ABSTRACT Introduction: Exercise can retard the effects of aging and improve the physical function of the elderly. Tai Chi is a widespread exercise practice among the elderly in China. Although studies show the positive effects of Tai Chi practice, there is no consensus about compared studies. Objective: Evaluate the impact of regular Tai Chi exercise on neuromuscular stability in the lower limbs of elderly people, comparing the results of practitioners between sedentary and walking elderly groups. Methods: Twenty-two Tai Chi practitioners were selected, with a mean age of 59.3±3.5 years and a mean practice time of 18.4±13.2 years. This experiment mainly tests the balance ability compared to individuals practicing walking and other sedentary individuals. Results: The muscle strength of the knee flexors and extensors in the Tai Chi group was significantly greater than in the sedentary group (p=0.001 to 0.00160°/sec; P=0.002 to 60°/sec extensors; p=0.002 to 120°/sec; 120°/sec flexors, p=0.003). Similarly, there was a significant difference in muscle strength between the Tai Chi group and the walking group (the P values of the flexors and extensors at both speeds were less than 0.001). Conclusion: Tai Chi, as a regular exercise, can increase muscle strength of the general knee flexors and extensors and improve the neuromuscular stability of lower limbs in the elderly. Evidence Level II; Therapeutic Studies - Investigating the result.


RESUMO Introdução: Exercícios podem retardar os efeitos do envelhecimento e melhorar a função física dos idosos. O Tai Chi é uma prática popular de exercício entre os idosos na China.

Objetivo: Avaliar o efeito do exercício regular de Tai Chi sobre a estabilidade neuromuscular nos membros inferiores em idosos, comparando os resultados dos praticantes entre grupos idosos de sedentários e praticantes de caminhada. Métodos: Foram selecionados vinte e dois praticantes de Tai Chi, com idade média de 59,3±3,5 anos com tempo médio de prática de 18,4±13,2 anos. Este experimento testa principalmente a capacidade de equilíbrio comparando aos indivíduos que praticam caminhada e outros sedentários. Resultados: A força muscular dos flexores e extensores do joelho no grupo Tai Chi foi significativamente maior do que no grupo sedentário (p=0,001 a 0,00160°/s; P=0,002 a extensores de 60°/s; p=0,002 a 120°/s; flexores de 120°/seg, p=0,003). Similarmente, houve uma diferença significativa na força muscular entre o grupo Tai Chi e o grupo de caminhada (os valores P dos flexores e extensores em ambas as velocidades foram inferiores a 0,001). Conclusão: Exercícios regulares, como o Tai Chi, podem alterar a força muscular dos flexores e extensores gerais do joelho, e melhorar a estabilidade neuromuscular dos idosos nos membros inferiores. Nível de evidência II; Estudos Terapêuticos - Investigação de Resultados.

ABSTRACT

Tai Chi and Qigong (TCQ) are regarded as major therapies of complementary and alternative medicine (CAM), and welcomed by increasing practitioners worldwide for their efficacy in various health issues. To better learn about the popularity of TCQ in the United States, the related data collected from 2007, 2012 and 2017 questionnaires of the National Health Interview Survey (NHIS) were examined and analyzed. The result showed that adult TCQ practitioners in the US increased substantially from 2007-2017, the percentage of Tai Chi practitioners in adult population was 1.0% in 2007, and Qigong practitioners 0.3%; Tai Chi practitioners was 1.1% in 2012, and Qigong practitioners 0.3%; in 2017, Tai Chi practitioners was 1.5%, and Qigong practitioners 0.5%. The top three reasons for using TCQ were: 82.4% for general wellness or disease prevention, 64.6% to improve or enhance energy, and 35.1% recommended by family, friends or co-workers. The health benefits of TCQ, the demand for complementary therapies and increasing research evidences were positive factors for the growth, while there are also challenges including insufficiencies in scientific researches and lacking of standardized teaching system. To promote the future development of TCQ in the US and oversea countries, we should optimize the research methods and standardize the teaching system, encourage the exchange and training of TCQ related professionals, and promote the integration of TCQ into conventional medical system and other related industries.

ABSTRACT

Objective To analyze muscle pre-activation and surface electromyography (sEMG) characteristics of knee and ankle joints of long-term Tai Chi practitioners during brush-knee twist-step and normal walking, and explore the neuromuscular control strategies of Tai Chi to prevent falls. Methods Vicon motion capture system, Kistler force plate, and Noraxon sEMG system were synchronously used to collect the EMG signals of the rectus femoris, biceps femoris, tibialis anterior muscle, lateral head of gastrocnemius and body posture information during brush-knee twist-step and normal walking. The pre-activation and co-contraction of knee and ankle joints were calculated by integrated EMG of the rectus femoris/biceps femoris, tibial anterior/lateral gastrocnemius muscles. Results Compared with normal walking, the average time of brush-knee twist-step in four phases was significantly increased. There was a significant difference in the percentage of time in four phases. The knee joint co-contraction level and pre-activation level decreased, and the ankle joint co-contraction level and pre-activation level increased. Conclusions Long-term Tai Chi exercises may increase the activation level of the muscles around knee joints and enhance the synergy in muscle groups to help stabilize the joint. The results provide references for rehabilitation assessment and training of neuromuscular control disorders.

ABSTRACT

ABSTRACT BACKGROUND: Rheumatoid arthritis (RA) is a chronic disease with higher prevalence among women aged between 30 and 50 years and general prevalence of 1% worldwide. Interventions promoting improvement of quality of life for individuals with RA are required. Tai Chi appears to be a low-cost alternative, with studies showing positive results from this technique. However, regarding aspects of RA such as pain and sensitivity, studies remain inconclusive. OBJECTIVES: To compare the effectiveness of the Tai Chi method for treating patients diagnosed with rheumatoid arthritis, among systematic reviews. DESIGN AND SETTING: Overview of systematic reviews with Cochrane and non-Cochrane methodology. METHODS: Systematic reviews involving quasi-randomized and randomized clinical trials (RCTs) on use of Tai Chi, with no restrictions regarding the date and language of publication, were included. RESULTS: Three systematic reviews were included. The effects of Tai Chi associated with education and stretching exercises versus education and stretching were evaluated in these reviews. They showed that improvements in the variables of mood, depression and functional index were associated with use of Tai Chi. CONCLUSIONS: The findings suggest that clinical improvement was achieved, although not statistically significant with regard to pain and disease pattern, as assessed using the ACR20 measurement. Improvements relating to disability and quality of life were also seen. There was a low level of evidence and therefore caution in data analysis is recommended. The three studies included showed poor reliability for providing an accurate and complete summary of use of Tai Chi among people diagnosed with rheumatoid arthritis. PROSPERO: CRD42019125501.

ABSTRACT Introduction: The population of older adults is increasing and an emergent need to implement strategies aimed at recovering or maintaining their health is observed. In this sense, techniques such as Tai Chi could contribute because they have demonstrated bringing diverse benefits for those who practice them, including improvements in the concentration, memory, gait, and equilibrium, a reduction in the risk of falls, a strengthening of the cardiovascular system, and a reduction of stress and depression, among other benefits. Objective: To analyze the scientific evidence on the use of Tai Chi as a health promoter and preserver among older adults. Development: This bibliographic review was conducted during 2013-2019 on the Pubmed, Dialnet, SciELO, LILACS, ScienceDirect and Academic Google databases. The keywords used were Tai Chi Chuan, Tai Ji Quan, and Tai Chi. After filtering through the eligibility criteria, 29 articles were selected for the review. Results: An important percentage of the articles were focused on the attention to physical symptoms which impair the mobility of older adults; nevertheless, some studies addressed psychological issues such as stress, anxiety, sleep disorders, depression, and anger-tension, as well. In these studies, the practice of Tai Chi was associated with health improvements among older adults. Conclusions: Tai Chi is an alternative therapy to promote and maintain health among older adults. This technique is easy to learn, and its practice is not expensive. No adverse reactions during or after the practice of this technique were reported in the studies of this literature review. Therefore, the nursing professional can recommend Tai Chi practice to be implemented as a complementary healthcare measure for older adults.

ABSTRACT

BACKGROUND@#Sleep disorders are common in older adults and have a negative influence on their physical and mental health. General aerobic exercises (GAEs) have long been used in the treatment of sleep disorders as a non-pharmacological measure. However, there is no consensus on the efficacy of traditional Chinese exercises (TCEs) for treating sleep disorders in older adults and the difference between TCEs and GAEs.@*OBJECTIVE@#This study assessed the effects of TCEs and GAEs on the sleep quality of older adults and the differences between these two interventions.@*SEARCH STRATEGY@#PubMed, Embase, Cochrane Library, Web of Science, China Biology Medicine disc, China National Knowledge Infrastructure, China Science Journal Database and Wanfang Data were searched from their inception to August 2020.@*INCLUSION CRITERIA@#Randomized controlled trials (RCTs) that evaluated the effects of TCEs and GAEs on older adults with sleep disorders were included.@*DATA EXTRACTION AND ANALYSIS@#Data were extracted by two researchers working independently. The risk bias of included studies was assessed using the Cochrane Handbook for Systematic Reviews of Interventions 5.1.0 and the quality of evidence was assessed using the Grades of Recommendation, Assessment, Development and Evaluation approach. The Pittsburgh Sleep Quality Index (PSQI) was used to estimate sleep quality. Meta-analyses were performed to assess the total PSQI score of the exercise intervention as the primary outcome, and the scores of subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleep medication and daytime dysfunction were assessed as secondary outcomes. Subgroup, sensitivity, and meta-regression analyses were conducted to assess the contribution of covariables to heterogeneity.@*RESULTS@#A total of 22 RCTs (including 1747 participants) were included in the meta-analysis. The results indicated that TCEs (weighted mean difference [WMD] = -2.14, 95% confidence interval [CI] [-2.82, -1.46], P < 0.001; heterogeneity: P < 0.001, I@*CONCLUSION@#Current evidence shows that both TCEs and GAEs, as complementary and non-pharmacological approaches, help to improve the sleep quality in older adults with potentially clinical implications; however, there was not enough evidence to conclude the difference between them. More rigorous and high-quality RCTs are needed to arrive at reliable conclusions.

ABSTRACT

OBJECTIVE@#To study the effect of Tai Chi (TC) and resistance training (RT) with different intensity on the cancer-related fatigue (CRF) and quality of life (QoL) of middle-aged and elderly cancer patients.@*METHODS@#Totally 120 cancer patients were enrolled and randomly assigned to 4 groups by a random number table, including TC group, high-intensity 60% one repetition maximum (1-RM) RT group (HIRT), low-intensity (30% 1-RM) RT group (LIRT) and control group, 30 patients in each group. Participants in the TC group received 24-form simplified Yang-style TC training at a frequency of 40 min per day, 3 days per week for 12 weeks. Patients in the two RT groups received 10 sessions, 6 designated movements per day, 3 days per week for 12 weeks. The 1-RM of 6 muscle groups, fat mass (FM), lean body mass (LBM), along with the scores of Brief Fatigue Inventory (BFI), QoL questionnaire for Chinese cancer patients receiving chemobiotherapy (QLQ-CCC), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9) and Pittsburgh Sleep Quality Index (PSQI) were measured before and after training. The adverse effect was also observed.@*RESULTS@#After 12-week intervention, patients in both TC and RT groups showed significant improvements in CRF and QLQ-CCC compared to pre-treatment (P<0.05). Compared with the LIRT and TC groups, patients in the HIRT group improved more significantly in increasing muscle strength and LBM, and reducing in FM (P<0.05). Patients in the TC group significantly increased in lower limb muscle strength compared with the LIRT group (P<0.05). In addition, patients in the TC group showed more significant improvements in scores of GAD-7, PHQ-9 and PSQI than 2 RT groups (P<0.05).@*CONCLUSIONS@#TC and RT, both low- and high-intensity training, can significantly increase muscle strength, reduce CRF and improve QoL in the middle-aged and elderly cancer patients. TC has a better effect than RT in terms of sleep quality and mental health. The long-term application is needed to substantiate the effect of TC as an alternative exercise in cancer patients.

ABSTRACT

The purpose of this study is to analyze the biomechanics of ankle cartilage and ligaments during a typical Tai Chi movement-Brush Knee and Twist Step (BKTS). The kinematic and kinetic data were acquired in one experienced male Tai Chi practitioner while performing BKTS and in normal walking. The measured parameters were used as loading and boundary conditions for further finite element analysis. This study showed that the contact stress of the ankle joint during BKTS was generally less than that during walking. However, the maximum tensile force of the anterior talofibular ligament, the calcaneofibular ligament and the posterior talofibular ligament during BKTS was 130 N, 169 N and 89 N, respectively, while it was only 57 N, 119 N and 48 N during walking. Therefore, patients with arthritis of the ankle can properly practice Tai Chi. Practitioners with sprained lateral ligaments of the ankle joint were suggested to properly reduce the ankle movement range during BKTS.

ABSTRACT

Objective To investigate the influence of Tai Chi posture on knee joint load and the strategy of coordinated muscle contraction. Methods Twenty Tai Chi practitioners with more than 3 years of Tai Chi practice was recruited. By using high-speed motion capture system andthree-dimensional force plate, the adduction angle, tibial angle, joint force, joint torque of the supporting leg during the Tai Chi step lunge movement were collected, and the quadriceps and gastrocnemius muscle strength were obtained through simulation method. The muscle strength performance, recruitment mode and activation method of baseline step, toe-out step and toe-in step were compared. ResultsThe tibial angle and adduction force increased in the toe-out step but those parameters in the toe-in step remained unchanged; the strength of the medial femoris, semimembranosus, semitendinosus and lateral gastrocnemius muscle increased in the toe-out step; the external femoral muscle and medial gastrocnemius muscle increased in the toe-in step. The gastrocnemius muscle was preferentially activated than the quadriceps muscle, and the way of muscle recruitment changed. Conclusions Tai Chi posture will change the way of muscle force recruitment and affect the knee joint function. Standardized movements can be used as the reference for osteoarthritis exercise therapy and have some significance in clinical application.
