    Peng, Philip W H

    2012-01-01

    In the last 2 decades, a growing body of research aimed at investigating the health benefits of Tai Chi in various chronic health conditions has been recognized in the literature. This article reviewed the history, the philosophy, and the evidence for the role of Tai Chi in a few selected chronic pain conditions. The ancient health art of Tai Chi contributes to chronic pain management in 3 major areas: adaptive exercise, mind-body interaction, and meditation. Trials examining the health benefit of Tai Chi in chronic pain conditions are mostly low quality. Only 5 pain conditions were reviewed: osteoarthritis, fibromyalgia, rheumatoid arthritis, low back pain, and headache. Of these, Tai Chi seems to be an effective intervention in osteoarthritis, low back pain, and fibromyalgia. The limitations of the Tai Chi study design and suggestions for the direction of future research are also discussed.

    Tai chi is a complex multicomponent mind-body exercise. Many studies have provided evidence that tai chi benefits patients with a variety of chronic disorders. This form of mind-body exercise enhances cardiovascular fitness, muscular strength, balance, and physical function and seems to be associated with reduced stress, anxiety, and depression and improved quality of life. Thus, despite certain limitations in the evidence, tai chi can be recommended to patients with osteoarthritis, rheumatoid arthritis, and fibromyalgia as a complementary and alternative medical approach. This article overviews the current knowledge about tai chi to better inform clinical decision making for rheumatic patients. Copyright © 2011 Elsevier Inc. All rights reserved.

    This article analyzes the philosophy underpinning Tai Chi practice in light of nursing epistemology. The first half of the article reviews the general characteristics of major Chinese philosophical traditions that have been merged in Tai Chi: Confucianism, Daoism, and Buddhism. In the second half, themes of integration and praxis in Tai Chi are linked with Carper's fundamental patterns of knowing in nursing. Tai Chi is a practical fusion of humanistic philosophy with an experiential dimension of movement in a nondualistic foundation. The author argues that TC philosophy can be applied to integrated knowledge development and nursing praxis.

    Tai-chi chuan is popular worldwide especially in China. People practice tai-chi chuan daily with faith believing that they will be rewarded with health and varieties of other rewords. The Tai Chi Chuan Theory by Master Chang and the Tai Chi Chuan Theory by Master Wang are translated to be the baseline of the tai-chi chuan. The theory described in these two papers clearly shows that the tai-chi power source is the combination of the two antigravity forces distinction by each foot. The ying, yang and hollowed, solid discussed in the papers are the properties and body relationship of the two antigravity forces. The antigravity forces presented inside of body are as air to the balloon termed chi. However chi could be generated by any muscle pressing; only the antigravity forces from feet are called nature chi that has the maximum strength of the person. When a person is soft, as an infant the nature chi will fulfill entire body with no time and effort. The sequence forms were designed for deploying the nature chi in speed and power. The combination of chi and tai-chi form make tai chi chuan supreme than other kinds of martial art. In the training process chi massages whole body many time for a sequence form practice that stimulate all organs and could lead to cure body diseases, lose weight, postpone aging process, and remove the aging symptoms. For the people practicing in the park daily with proper guidance they will fulfill their wishes. Tai chi exercise could also apply to other sports as in dancing and golfing they are discussed at the end of the paper.

    Background. The present study aimed to evaluate and compare the effect of two different types of Tai Chi programs on the Functional Movement Screening (FMS) in older adults. Methods. Ninety older adults (65.5 ± 4.6 years old) who met the eligibility criteria were randomized into three different groups based on a ratio of 1 : 1 : 1: a traditional Tai Chi exercise (TTC), a simplified Tai Chi exercise (TCRT), or a control group (routine activity). The FMS consisted of the deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg rise, trunk stability push-up, and rotatory stability, which was used to measure physical function before the present study and after six months of Tai Chi interventions. Results. Seventy-nine participants completed the present study (control = 27, TTC = 23, and TCRT = 29). Significant improvement on the FMS tests between the baseline and after the six-month intervention was observed in both Tai Chi programs, whereas no significant improvement was observed in the control group. In addition, participants in the TCRT group demonstrated greater improvement than those in the TTC group. Conclusions. The TCRT is more effective in improving the physical function in older adults when compared to the traditional Tai Chi modality, particularly for improving balance.

    2015-01-01

    Background. This study examined whether simplified Tai Chi resistance training is superior to traditional Tai Chi in slowing bone loss in postmenopausal women. Methods. This prospective trial included 119 postmenopausal women (age: 52-65 years). Subjects were randomly assigned to participate in a traditional Tai Chi program (TTC, n = 40), a simplified Tai Chi resistance training program (TCRT, n = 40), or a blank control group (routine activity, n = 39). The TTC involved traditional Yang Style Tai Chi. The primary outcome was the change of lumbar bone mass density (L2-L4) at 12 months over the baseline. Femoral neck and Ward's triangle were also measured using dual-energy X-ray absorptiometry. Results. The L2-L4 density was significantly lower at 12 months in comparison to the baseline in the blank control group. In both the TCRT and TTC groups, the L2-L4 density was comparable to the baseline. There was a trend for less bone loss in the TCRT than in the TTC group. Similar findings were observed with femoral neck and Ward's triangle. Conclusion. Simplified Tai Chi resistance training could slow bone loss in menopausal women. The results also suggested, but did not confirm, superiority to traditional Tai Chi.

    Recently, Tai Chi, which is one of the Chinese traditional martial arts, has been receiving attention. The main feature of Tai Chi is its flowing movements including loosening up, relaxing, and practicing meditation with slow abdominal respiration. Tai Chi is widely taken as part of health-promotion activities or rehabilitation training, and significant mental and physical effects have been reported so far. In this review report, Tai Chi was confirmed to be beneficial not only as a rehabilitation training for old people or patients with various diseases but also as an exercise for healthy people. These findings suggest the potential of Tai Chi as a complementary and alternative therapy.

    2008-12-01

    The objective of this review is to assess the effectiveness of tai chi as a treatment option for Parkinson's disease (PD). We have searched the literature using 21 databases from their inceptions to January 2008, without language restrictions. We included all types of clinical studies regardless of their design. Their methodological quality was assessed using the modified Jadad score. Of the seven studies included, one randomised clinical trial (RCT) found tai chi to be superior to conventional exercise in terms of the Unified PD Rating Scale (UPDRS) and prevention of falls. Another RCT found no effects of tai chi on locomotor ability compared with qigong. The third RCT failed to show effects of tai chi on the UPDRS and the PD Questionnaires compared with wait list control. The remaining studies were either non-randomised (n=1) or uncontrolled clinical trials (n=3). Collectively these data show that RCTs of the tai chi for PD are feasible but scarce. Most investigations suffer from methodological flaws such as inadequate study design, poor reporting of results, small sample size, and publication without appropriate peer review process. In conclusion, the evidence is insufficient to suggest tai chi is an effective intervention for PD. Further research is required to investigate whether there are specific benefits of tai chi for people with PD, such as its potential effect on balance and on the frequency of falls.

    We compared the physiological work, judged by oxygen uptake, esophageal pressure swing and diaphragm electromyography, elicited by Tai Chi compared with that elicited by constant rate treadmill walking at 60% of maximal load in eleven patients with COPD (Mean FEV1 61% predicted, FEV1/FVC 47%). Dynamic hyperinflation was assessed by inspiratory capacity and twitch quadriceps tension (TwQ) elicited by supramaximal magnetic stimulation of the femoral nerve was also measured before and after both exercises. The EMGdi and esophageal pressure at the end of exercise were similar for both treadmill exercise and Tai Chi (0.109±0.047 mV vs 0.118±0.061 mV for EMGdi and 22.3±7.1 cmH2O vs 21.9±8.1 cmH2O for esophageal pressure). Moreover the mean values of oxygen uptake during Tai Chi and treadmill exercise did not differ significantly: 11.3 ml/kg/min (51.1% of maximal oxygen uptake derived from incremental exercise) and 13.4 ml/kg/min (52.5%) respectively, p>0.05. Respiratory rate during Tai Chi was significantly lower than that during treadmill exercise. Both Tai Chi and treadmill exercise elicited a fall in IC at end exercise, indicating dynamic hyperinflation, but this was statistically significant only after treadmill exercise. TwQ decreased significantly after Tai Chi but not after treadmill. We conclude that Tai Chi constitutes a physiologically similar stimulus to treadmill exercise and may therefore be an acceptable modality for pulmonary rehabilitation which may be culturally more acceptable in some parts of the world.

A randomized control trial of two groups (control and Tai Chi group). Northeastern academic medical center. A convenience sample of eleven female nurses (mean age 54.4 years). The Tai Chi group (n = 6) was asked to attend Tai Chi classes once a week offered at their worksite and to practice on their own for 10 minutes each day at least 4 days per week for 15 weeks. Controls (n = 5) received no intervention. SF-36 Health Survey, Nursing Stress Scale (NSS), Perceived Stress Scale (PSS), Sit-and-Reach test, Functional Reach test, the Work Limitations Questionnaire, workplace injury and unscheduled time off. The two study groups were compared descriptively and changes across time in the intervention versus control were compared. The Tai Chi group took no unscheduled time-off hours, whereas, the control group was absent 49 hours during the study period. There was also a 3% increase in work productivity and significant improvement in functional reach (p=0.03) compared to the control group. Other outcomes were not statistically significant. This pilot study demonstrates the feasibility of Tai Chi with older female workers as a cost effective wellness option in the workplace; thus encouraging replication with a larger sample.

    Heart disease is a chronic condition needing lifetime secondary prevention measures to decrease morbidity and mortality, and to improve quality of life. Cardiac rehabilitation exercise training, one aspect of cardiac recovery, traditionally includes some form of aerobic fitness and, more recently, muscle strength training to improve exercise tolerance. Tai chi, widely practiced in China for centuries, is a popular form of exercise among older Chinese persons associated with enhanced well-being and health among traditional Chinese practitioners. Recent research has reported improvement in cardiorespiratory function, balance and postural stability, fall prevention, and stress reduction. A review of the literature suggests potential benefits from tai chi exercise performed as an adjunct to cardiac rehabilitation exercise training. Tai chi is cost-effective and facilitates a lifestyle of health-related behavior practices.

    Tai Chi is a callisthenic exercise form that incorporates aerobic exercise with diaphragmatic breathing. These two aspects alone have been shown to enhance the heart rate variability, warranting research into the effects of Tai Chi on autonomic nervous system modulation and heart rate variability. A low heart rate variability has been shown to be indicative of compromised health. Any methods to enhance the heart rate variability, in particular, non-pharmacological methods, are therefore seen as beneficial to health and are sought after. The aim of this review was to comprehensively summarize the currently published studies regarding the effects of Tai Chi on heart rate variability. Both consistent and inconsistent findings are presented and discussed, and an overall conclusion attained which could benefit future clinical studies. Copyright © 2016 Elsevier Ltd.

    In order to maintain stable upright stance, the postural control system must account for the continuous perturbations to the body's center-of-mass including those caused by spontaneous respiration. Both aging and disease increase "posturo-respiratory synchronization;" which reflects the degree to which respiration affects postural sway fluctuations over time. Tai Chi training emphasizes the coordination of respiration and bodily movements and may therefore optimize the functional interaction between these two systems. The purpose of the project was to examine the effect of Tai Chi training on the interaction between respiration and postural control in older adults. We hypothesized that Tai Chi training would improve the ability of the postural control system to compensate for respiratory perturbations and thus, reduce posturo-respiratory synchronization. Participants were recruited from supportive housing facilities and randomized to a 12-week Tai Chi intervention (n=28; 86 ± 5 yrs) or educational-control program (n=34, 85 ± 6 yrs). Standing postural sway and respiration were simultaneously recorded with a force plate and respiratory belt under eyes-open and eyes-closed conditions. Posturo-respiratory synchronization was determined by quantifying the variation of the phase relationship between the dominant oscillatory mode of respiration and corresponding oscillations within postural sway. Groups were similar in age, gender distribution, height, body mass, and intervention compliance. Neither intervention altered average sway speed, sway magnitude or respiratory rate. As compared to the education-control group, however, Tai Chi training reduced posturo-respiratory synchronization when standing with eyes open or closed (ppostural control or respiration, yet reduced the coupling between respiration and postural control. The beneficial effects of Tai Chi training may therefore stem in part from optimization of this multi-system interaction.

    2012-12-01

    Rheumatologic diseases (e.g., fibromyalgia, osteoarthritis, and rheumatoid arthritis) consist of a complex interplay between biologic and psychological aspects, resulting in therapeutically challenging chronic conditions to control. Encouraging evidence suggests that Tai Chi, a multi-component Chinese mind-body exercise, has multiple benefits for patients with a variety of chronic disorders, particularly those with musculoskeletal conditions. Thus, Tai Chi may modulate complex factors and improve health outcomes in patients with chronic rheumatologic conditions. As a form of physical exercise, Tai Chi enhances cardiovascular fitness, muscular strength, balance, and physical function. It also appears to be associated with reduced stress, anxiety, and depression, as well as improved quality of life. Thus, Tai Chi can be safely recommended to patients with fibromyalgia, osteoarthritis, and rheumatoid arthritis as a complementary and alternative medical approach to improve patient well-being. This review highlights the current body of knowledge about the role of this ancient Chinese mind-body medicine as an effective treatment of rheumatologic diseases to better inform clinical decision-making for our patients.

    2010-03-01

    Full Text Available Abstract Background Post-menopausal osteopenic women are at increased risk for skeletal fractures. Current osteopenia treatment guidelines include exercise, however, optimal exercise regimens for attenuating bone mineral density (BMD loss, or for addressing other fracture-related risk factors (e.g. poor balance, decreased muscle strength are not well-defined. Tai Chi is an increasingly popular weight bearing mind-body exercise that has been reported to positively impact BMD dynamics and improve postural control, however, current evidence is inconclusive. This study will determine the effectiveness of Tai Chi in reducing rates of bone turnover in post-menopausal osteopenic women, compared with standard care, and will preliminarily explore biomechanical processes that might inform how Tai Chi impacts BMD and associated fracture risks. Methods/Design A total of 86 post-menopausal women, aged 45-70y, T-score of the hip and/or spine -1.0 and -2.5, have been recruited from primary care clinics of a large healthcare system based in Boston. They have been randomized to a group-based 9-month Tai Chi program plus standard care or to standard care only. A unique aspect of this trial is its pragmatic design, which allows participants randomized to Tai Chi to choose from a pre-screened list of community-based Tai Chi programs. Interviewers masked to participants' treatment group assess outcomes at baseline and 3 and 9 months after randomization. Primary outcomes are serum markers of bone resorption (C-terminal cross linking telopeptide of type I collagen, bone formation (osteocalcin, and BMD of the lumbar spine and proximal femur (dual-energy X-ray absorptiometry. Secondary outcomes include health-related quality-of-life, exercise behavior, and psychological well-being. In addition, kinetic and kinematic characterization of gait, standing, and rising from a chair are assessed in subset of participants (n = 16 to explore the feasibility of modeling skeletal

    This article describes the authors' experience and strategies in teaching Tai Chi, a gentle exercise derived from an ancient Chinese martial art, to mildly cognitively impaired elders to relieve osteoarthritic knee pain. The 12-form Sun-style Tai Chi, a set of Tai Chi forms endorsed by the American Arthritis Foundation, was used in the program. Teaching Tai Chi to elders with mild cognitive impairment requires particular strategies tailored to their physical and cognitive frailty. When effectively taught, Tai Chi can be a unique and cost-effective intervention for elders with knee pain caused by osteoarthritis.

    The aim of this review was to update and critically evaluate the evidence from randomised clinical trials (RCTs) of tai chi for patients with type 2 diabetes mellitus (T2DM). Twelve databases were searched by August 2014. Fifteen RCTs met all of the inclusion criteria. One RCT compared the effects of tai chi with sham exercise and failed to show the effectiveness of tai chi on fasting blood glucose (FBG), or HbA1c. The other four RCTs tested the effects of tai chi compared with various types of exercise and the meta-analysis failed to show an FBG-lowering effect. Five RCTs compared the effects of tai chi with an anti-diabetic medication and the meta-analysis showed favourable effects of tai chi on FBG. One RCT showed the positive effects of tai chi plus standard care on HbA1c and FBG compared with standard care alone. Four RCTs compared the effects of tai chi to no treatment and the meta-analysis failed to show the positive effects of tai chi on HbA1c. Three RCTs reported superior effects of tai chi on quality of life. In conclusion, the existing trial evidence is not convincing enough to suggest that tai chi is effective for managing patients with T2DM.

    Tai Chi is an ancient Chinese martial art which incorporates elements of strengthening, balance, postural alignment and concentration. The benefits of Tai Chi in the healthy population have been widely examined. In comparison, only three studies have evaluated the effects of Tai Chi in people with chronic obstructive pulmonary disease (COPD). Existing evidence suggests that the exercise intensity of Tai Chi reaches a moderate level in people with COPD. Furthermore, a short-term program of Tai Chi improves exercise capacity, health-related quality of life, balance and quadriceps strength in people with mild to moderate COPD. More studies are warranted to examine the effects of different styles of Tai Chi and the long-term benefits of Tai Chi as an exercise regimen for people with COPD.

    Stress and a sedentary lifestyle are major determinants of cardiovascular disease (CVD). As tai chi involves exercise and can help in stress reduction, it may be effective in the primary prevention of CVD. To determine the effectiveness of tai chi for the primary prevention of CVD. We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 11, 2013); MEDLINE (Ovid) (1946 to November week 3, 2013); EMBASE Classic + EMBASE (Ovid) (1947 to 6 December 2013); Web of Science (Thomson Reuters) (1970 to 6 December 2013); PsycINFO (Ovid) (1806 to December week 1, 2013); Database of Abstracts of Reviews of Effects (DARE); Health Technology Assessment Database and Health Economics Evaluations Database (Issue 4, 2013). We also searched the Allied and complementary Medicine Database (AMED) and OpenGrey (inception to October 2012) and several Asian databases. We searched trial registers and reference lists of reviews for further studies. We applied no language restrictions. Randomised controlled trials of tai chi lasting at least three months involving healthy adults or adults at high risk of CVD. The comparison group was no intervention or minimal intervention. The outcomes of interest were CVD clinical events and CVD risk factors. We excluded trials involving multifactorial lifestyle interventions or focusing on weight loss to avoid confounding. Two review authors independently selected trials for inclusion, abstracted the data and assessed the risk of bias. We identified 13 small trials (1520 participants randomised) and three ongoing trials. All studies had at least one domain with unclear risk of bias, and some studies were at high risk of bias for allocation concealment (one study) and selective reporting (two studies). Duration and style of tai chi differed between trials. Seven studies recruited 903 healthy participants, the other studies recruited people with borderline hypertension or hypertension, elderly

    Cardiac rehabilitation improves physical, cognitive and psychosocial functioning, yet services are greatly underutilized with increasing patterns of attrition over time. Tai Chi has been suggested as a possible adjunct to cardiac rehabilitation exercise training. To describe differences in physical, cognitive and psychosocial functioning among adults ≥ 45 years old attending phase III cardiac rehabilitation, who have or have not self-selected Tai Chi exercise as an adjunct physical activity. A cross-sectional design compared subjects attending group-based Wu style Tai Chi classes plus cardiac rehabilitation, with cardiac rehabilitation only. Subjects had a battery of physical and cognitive functioning tests administered to examine aerobic endurance, balance, strength, and flexibility, verbal retrieval/recall, attention, concentration and tracking. Subjects completed a health survey to ascertain cardiac event information, medical history, and psychosocial functioning (i.e. health-related quality of life, stress, depressive symptoms, social support, and Tai Chi self-efficacy). A total of 51 subjects (75% married, 84% college-educated, 96% White/European-American) participated. Subjects were on average 70 (± 8) years old and had attended cardiac rehabilitation for 45 (± 37) months. Approximately 45% (n = 23) attended Tai Chi classes plus cardiac rehabilitation, while 55% (n = 28) attended cardiac rehabilitation only. Subjects attending Tai Chi plus cardiac rehabilitation had better balance, perceived physical health, and Tai Chi self-efficacy compared to those attending cardiac rehabilitation only (p ≤ 0.03). Tai Chi can be easily implemented in any community/cardiac rehabilitation facility, and may offer adults additional options after a cardiac event.

    [Purpose] The aim of the present study was to seek evidence for the effectiveness of Tai Chi for patients with knee osteoarthritis (KOA). [Subjects and Methods] Systematic searches were conducted of the China Journals Full-text Database, Pubmed, Medline, Science Direct-Online Journals and CINAHL for studies published between 2000 and 2012. Studies were evaluated based on following inclusion criteria: 1) design: randomized control, clinical trial; 2) subjects: patients with a knee osteoarthritis diagnosis; 3) intervention: exercise involving Tai Chi; 4) studies published in English or Chinese. [Results] Six randomized control studies involving Tai Chi and knee osteoarthritis were found. [Conclusion] Tai Chi was an effective way of relieving pain and improving physical function. Further randomized controlled trials with large sample sizes and long training period are needed to compare groups who perform Tai Chi training with other groups who undergo other forms of physical exercise in order to confirm the efficacy of Tai Chi.

    2010-11-01

    To determine the immediate effects of a combined form of Tai chi/yoga. 38 adults participated in a 20-min Tai chi/yoga class. The session was comprised of standing Tai chi movements, balancing poses and a short Tai chi form and 10 min of standing, sitting and lying down yoga poses. The pre- and post- Tai chi/yoga effects were assessed using the State Anxiety Inventory (STAI), EKG, EEG and math computations. Heartrate increased during the session, as would be expected for this moderate-intensity exercise. Changes from pre to post-session assessments suggested increased relaxation including decreased anxiety and a trend for increased EEG theta activity. The increased relaxation may have contributed to the increased speed and accuracy noted on math computations following the Tai chi/yoga class. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Full Text Available Tai chi exercise has been shown to improve physiological and psychosocial functions, well-being, quality of life, and disease conditions. The biological mechanisms by which tai chi exerts its holistic effects remain unknown. We investigated whether tai chi practice results in positive epigenetic changes at the molecular level. Design. The DNA methylation profiles of sixty CpG-dinucleotide marks in female tai chi practitioners (N=237; 45–88 years old who have been practising tai chi for three or more years were compared with those of age-matched control females (N=263 who have never practised tai chi. Results. Six CpG marks originating from three different chromosomes reveal a significant difference (P<0.05 between the two cohorts. Four marks show losses while two marks show gains in DNA methylation with age in the controls. In the tai chi cohort all six marks demonstrate significant slowing (by 5–70% of the age-related methylation losses or gains observed in the controls, suggesting that tai chi practice may be associated with measurable beneficial epigenetic changes. Conclusions. The results implicate the potential use of DNA methylation as an epigenetic biomarker to better understand the biological mechanisms and the health and therapeutic efficacies of tai chi.

    Tai Chi is a part of traditional Chinese culture and a treasure of Chinese Wu Shu. Its excel ent value for health and elegant taste of culture have long been known by people of the world. As the intensified efforts made for the exchange of Chinese and western economic and culture and the world globalization of economic and culture, Tai Chi has been spreaded to the five continents in more than 150 countries and the area, is deeplyloved by people. The Tai Chi faces al kinds of learners from different cultural backgrounds. This paper intends to research the cultural background and historical origin of Tai Chi movements andto explore the translation of Tai Chi, the process of how to deal with its national culture problem.In the first two chapters, the author mainly introduces the definition and characteristics of the Tai Chi and the relationship between Tai Chi and the Chinese culture. The other two chapters focus on the general methods of the translation of Tai Chi movement, and also giving author’s ownsuggestion on how to translate the Tai Chi movement more effectively and transmit Chinese culture.

    [Purpose] Medial knee osteoarthritis, a degenerative joint disease, affects adults. The external knee adduction moment, a surrogate knee-loading measure, has clinical implications for knee osteoarthritis patients. Tai Chi is a promising intervention for pain alleviation in knee osteoarthritis; however, the characteristics of external knee adduction moment during Tai Chi have not been established. [Subjects and Methods] During normal and Tai Chi walking, a gait analysis was performed to compare the external knee adduction moment moment-arm characteristics and paired t-tests to compare moment-arm magnitudes. [Results] A significant difference was observed in the average lateral direction of moment-arm magnitude during Tai Chi walking (-0.0239 ± 0.011 m) compared to that during normal walking (-0.0057 ± 0.004 m). No significant difference was found between conditions in average medial direction of moment-arm magnitude (normal walking: 0.0143 ± 0.010 m; Tai Chi walking: 0.0098 ± 0.014 m). [Conclusion] Tai Chi walking produced a larger peak lateral moment-arm value than normal walking during the stance phase, whereas Tai Chi walking and normal walking peak medial moment-arm values were similar, suggesting that medial knee joint loading may be avoided during Tai Chi walking.

    [Purpose] To investigate the effect of Tai Chi on cognitive and physical function in the elderly. [Subjects and Methods] A randomized trial design was used. A total 150 subjects were enrolled and were divided into Tai Chi and control groups. Subjects in the Tai Chi group participated Tai Chi for 6 months, and subjects in the control group participated in other non-athletic activities. [Results] There were no differences between the groups in the one leg standing time with eyes open, left grip strength, or the Frontal Assessment Battery at bedside after 3 and 6 months of intervention. The Mini-Mental State Examination scores after 3 and 6 months were higher in the Tai Chi group than in the control group. The right grip strength after 3 months increased more in the Tai Chi group than in the control group. Both the 5-m high walking speed and 10-m normal walking speed were significantly lower after 3 and 6 months of Tai Chi practice. [Conclusion] These results suggest that regular Tai Chi practice may improve cognitive and physical function in the elderly.

    Full Text Available It has recently been reported that the practice of Tai Chi reduces oxidative stress (OxS, but it is not clear whether walking or Tai Chi produces a greater antioxidant effect. The aim of the present study was to evaluate the effect of the practice of Tai Chi and walking on markers for OxS. We carried out a quasi-experimental study with 106 older adults between 60 and 74 years of age who were clinically healthy and divided into the following groups: (i control group (n=23, (ii walking group (n=43, and (iii Tai Chi group (n=31. We measured the levels of lipoperoxides (LPO, antioxidant enzymes superoxide dismutase (SOD and glutathione peroxidase (GPx, and total antioxidant status (TAS pre- and post-intervention in all subjects. The data were subjected to a covariant analysis. We found lower levels of LPO in the Tai Chi group compared with the walking group (Tai Chi, 0.261 ± 0.02; walking, 0.331 ± 0.02; control, 0.304 ± 0.023 µmol/L; P=0.05. Likewise, we observed significantly higher SOD activity and lower OxS-score in the Tai Chi group (P<0.05. Our findings suggest that the practice of Tai Chi produces a more effective antioxidant effect than walking.

    Tai Chi, a moving meditation, is examined for its efficacy in post-stressor recovery. Forty-eight male and 48 female Tai Chi practitioners were randomly assigned to four treatment groups: Tai Chi, brisk walking, mediation and neutral reading. Mental arithmetic and other difficult tests were chosen as mental challenges, and a stressful film was used to produce emotional disturbance. Tai Chi and the other treatments were applied after these stressors. After all treatments, the salivary cortisol level dropped significantly, and the mood states were also improved. In general the stress-reduction effect of Tai Chi characterized moderate physical exercise. Heart rate, blood pressure, and urinary catecholamine changes for Tai Chi were found to be similar to those for walking at a speed of 6 km/hr. Although Tai Chi appeared to be superior to neutral reading in the reduction of state anxiety and the enhancement of vigour, this effect could be partially accounted for by the subjects' high expectations about gains from Tai Chi. Approaches controlling for expectancy level are recommended for further assessment.

The objective of this systematic review is to more comprehensively summarize the evidence base of clinical studies of Tai Chi for healthcare. METHODS AND FINDINGS: We searched for all types of clinical studies on Tai chi in PubMed, the Cochrane Library and four major Chinese electronic databases from their inception to July 2013. Data were analyzed using SPSS17.0 software. A total of 507 studies published between 1958 and 2013 were identified, including 43 (8.3% systematic reviews of clinical studies, 255 (50.3% randomized clinical trials, 90 (17.8% non-randomized controlled clinical studies, 115 (22.7% case series and 4 (0.8% case reports. The top 10 diseases/conditions was hypertension, diabetes, osteoarthritis, osteoporosis or osteopenia, breast cancer, heart failure, chronic obstructive pulmonary disease, coronary heart disease, schizophrenia, and depression. Many healthy participants practiced Tai Chi for the purpose of health promotion or preservation. Yang style Tai Chi was the most popular, and Tai Chi was frequently practiced two to three 1-hour sessions per week for 12 weeks. Tai Chi was used alone in more than half of the studies (58.6%, while in other studies Tai Chi was applied in combination with other therapies including medications, health education and other physical therapies. The majority of studies (94.1% reported positive effects of Tai Chi, 5.1% studies reported uncertain effects and 0.8% studies reported negative effects. No serious adverse events related to Tai Chi were reported. CONCLUSIONS: The quantity and evidence base of clinical studies on Tai Chi is substantial. However, there is a wide variation in Tai Chi intervention studied and the reporting of Tai Chi intervention needs to be improved. Further well-designed and reported studies

    This study examined the effects of 24 weeks of Tai Chi Quan on the postural control of elderly women. A total of 43 women aged 55-68 years participated in the study. A Tai Chi group (n = 22) underwent an organized Tai Chi exercise, whereas the control group (n = 21) maintained a habitual, no-regular-exercise lifestyle. A Good Balance tester (Metitur, Finland) was used to measure the time, paths and velocity of the center of pressure (COP) of subjects during stance while shifting COP to targeted positions shown on a monitor. After 24 weeks, the Tai Chi group showed significantly shorter total (18.6%, p = 0.005), mediolateral (21.9%, p = 0.002) and anteroposterior (18.3%, p = 0.002) COP sway paths than the control group. The results indicate that 24 weeks of the Tai Chi exercise improved the efficiency of postural control for elderly women.

    Anxiety has become a global public health problem. Tai chi offers one possible way of reducing anxiety. The purpose of this study was to examine studies from 1989 to March 2014 to assess whether tai chi can be an efficacious approach for managing anxiety. A systematic search of Medline, CINAHL, and Alt HealthWatch databases was conducted for quantitative articles involving applications of tai chi for anxiety. A total of 17 articles met the inclusion criteria. Of these, 8 were from the United States, 2 from Australia, 2 from Japan, 2 from Taiwan, and 1 each from Canada, Spain, and China. Statistically significant results of anxiety reduction were reported in 12 of the studies reviewed. Despite the limitations of not all studies using randomized controlled designs, having smaller sample sizes, having different outcomes, having nonstandardized tai chi interventions, and having varying lengths, tai chi appears to be a promising modality for anxiety management.

    The aim of this study was to analyze the effects of therapeutic Tai Chi on balance, gait, and quality of life in chronic stroke patients. Twenty-two inpatients diagnosed with stroke were divided randomly into two groups: one treated with both general physical therapy and Tai Chi exercise (11 patients) and one treated with only general physical therapy (11 patients). Therapeutic Tai Chi included 10 different movements and was performed for 60 min, twice per week, for 6 weeks. Pretest and post-test measurements were recorded for sway length and sway velocity using Gaitview, the functional reach test, the dynamic gait index, the 10-m walking test, the timed up-and-go test, and SF-36 survey. Both the Tai Chi group and the control group showed a significant improvement in sway length and sway velocity, and the Tai Chi group showed greater improvement than the control group in degree of variation. In addition, only the Tai Chi group showed a significant result for functional reach test, the dynamic gait index, the 10-m walking test, the timed up-and-go test, and the Tai Chi group improved. In the quality of life, the therapeutic Tai Chi group showed a significant improvement in five items (physical function, pain, vitality, general health, mental health) among eight items in SF-36. This study confirmed that therapeutic Tai Chi influences the balance, gait, and life quality of stroke patients. Therefore, therapeutic Tai Chi can be used as an effective exercise in combination with general physical therapy to improve the balance, gait, and quality of life in stroke patients.

    This paper reports a study to examine change in psychosocial status following a 12-week Tai Chi exercise intervention among ethnic Chinese people with cardiovascular disease risk factors living in the United States of America. Regular participation in physical activity is associated with protection against cardioavascular disease, and improvements in physical and psychological health. Increasing amounts of scientific evidence suggests that mind-body exercise, such as Tai Chi, are related to improvements in mental health, emotional well-being, and stress reduction. No prior study has examined the effect of a Tai Chi exercise intervention on psychosocial status among people with cardiovascular disease risk factors. This was a quasi-experimental study. Participants attended a 60-minute Tai Chi exercise class three times per week for 12 weeks. Data were collected at baseline, 6 and 12 weeks following the intervention. Psychosocial status was assessed using Chinese versions of Cohen's Perceived Stress Scale, Profile of Mood States, Multidimensional Scale of Perceived Social Support, and Tai Chi exercise self-efficacy. A total of 39 participants, on average 66-year-old (+/-8.3), married (85%), Cantonese-speaking (97%), immigrants participated. The majority were women (69%), with stress (eta2 = 0.13) were found. In addition, Tai Chi exercise statistically significantly increased self-efficacy to overcome barriers to Tai Chi (eta2 = 0.19), confidence to perform Tai Chi (eta2 = 0.27), and perceived social support (eta2 = 0.12). Tai Chi was a culturally appropriate mind-body exercise for these older adults, with statistically significant psychosocial benefits observed over 12-weeks. Further research examining Tai Chi exercise using a randomized clinical trial design with an attention-control group may reduce potential confounding effects, while exploring potential mechanisms underlying the relaxation response associated with mind-body exercise. In addition, future studies

    Eun-Nam Lee

    2008-01-01

    Full Text Available We investigated the effects of tai chi on disease activity, flexibility and depression in patients with ankylosing spondylitis (AS. We allocated 40 patients to either a tai chi treatment group or a no-treatment control group. The tai chi group performed 60 min of tai chi twice weekly for eight consecutive weeks and 8 weeks of home-based tai chi, after which the group showed significant improvement in disease activity and flexibility compared to the control group. All outcome measures were significantly lower in the tai chi group than they were during pre-treatment, while they did not change in the control group. These findings suggest that tai chi can improve disease activity and flexibility for patients with AS. Tai chi is an easily accessible therapy for patients and, as such, may be an effective intervention for AS. However, we cannot completely discount the possibility that the placebo effect was responsible for the improvement.

    This study examined the effects of tai chi (TC) on biobehavioral factors associated with cardiovascular disease (CVD) risk in women. A randomized trial used a wait-list control group, pretest-posttest design. Data were collected immediately before, immediately after, and 2 months following the intervention. The study was community based in central Virginia. Women aged 35 to 50 years at increased risk for CVD. The 8-week intervention built on prior work and was designed to impact biobehavioral factors associated with CVD risk in women. Biological measures included fasting glucose, insulin, and lipids as well as C-reactive protein and cytokines. Behavioral measures included fatigue, perceived stress, depressive symptoms, social support, mindfulness, self-compassion, and spiritual thoughts and behaviors. A mixed effects linear model was used to test for differences between groups across time. In 63 women, TC was shown to decrease fatigue (∂ [difference in group means] = 9.38, p = .001) and granulocyte colony stimulating factor (∂ = 12.61, p = .052). Consistent with the study model and intervention design, significant changes observed 2 months post intervention indicated that TC may help down-regulate proinflammatory cytokines associated with underlying CVD risk, including interferon gamma (∂ = 149.90, p = .002), tumor necrosis factor (∂ = 16.78, p = .002), interleukin (IL) 8 (∂ = 6.47, p = .026), and IL-4 (∂ = 2.13, p = .001), and may increase mindfulness (∂ = .54, p = .021), spiritual thoughts and behaviors (∂ = 8.30, p = .009), and self-compassion (∂ = .44, p = .045). This study contributes important insights into the potential benefits and mechanisms of TC and, with further research, may ultimately lead to effective strategies for reducing CVD risk in women earlier in the CVD trajectory. © 2016 by American Journal of Health Promotion, Inc.

    The efficacy of Tai Chi (TC) to improve neuromuscular response characteristics underlying dynamic balance recovery in balance-impaired seniors at high risk for falling was examined during perturbed walking. Twenty-two subjects were randomized into TC or control groups. Nineteen subjects (68-92 years, BERG 44 or less) completed the study. TC training incorporated repetitive exercises using TC's essential motor/biomechanical strategies, techniques, and postural components. Control training used axial exercises, balance awareness/education and stress reduction. Groups trained 1.5 h/day, 5 days/week for 3 weeks. After post-testing, controls received TC training. Subjects walked across a force plate triggered to move forward 15 cm at 40 cm/s at heelstrike. Tibialis anterior and medial gastrocnemius responses during balance recovery were recorded from electromyograms. Four clinical measures of balance were also examined. TC subjects, but not controls, significantly reduced tibialis anterior response time from 148.92 +/- 45.11 ms to 98.67 +/- 17.22 ms (p < or = 0.004) and decreased co-contraction of antagonist muscles (p < or = 0.003) of the perturbed leg. All clinical balance measures significantly improved after TC. TC training transferred to improved neuromuscular responses controlling the ankle joint during perturbed gait in balance-impaired seniors who had surgical interventions to their back, hips, knees and arthritis. The fast, accurate neuromuscular activation crucial for efficacious response to slips also transferred to four clinical measures of functional balance. Significant enhancement was achieved with 3 weeks of training.

    It is important to identify effective non-pharmacological alternatives to stimulant medications that reduce symptoms of attention deficit hyperactivity disorder (ADHD). In this study of healthy young adults, we measured the effects of training in tai chi, which involves mindful attention to the body during movement. Using a non-randomized, controlled, parallel design, students in a 15-week introductory tai chi course (n = 28) and control participants (n = 44) were tested for ADHD indicators and cognitive function at three points over the course of the 15-weeks. The tai chi students' self-report of attention, but not hyperactivity-impulsivity, improved compared to controls. At baseline, inattention correlated positively with reaction time variability in an affective go/no-go task across all participants, and improvements in attention correlated with reductions in reaction time variability across the tai chi students. Affective bias changed in the tai chi students, as reaction times to positive- and negative-valenced words equalized over time. These results converge to suggest that tai chi training may help improve attention in healthy young adults. Further studies are needed to confirm these results and to evaluate tai chi as therapy for individuals with ADHD.

    The aim of this systematic review was to evaluate the existing evidence on the effectiveness and safety of Tai chi, which is critical to provide guidelines for clinicians to improve symptomatic management in patients with multiple sclerosis (MS). After performing electronic and manual searches of many sources, ten relevant peer-reviewed studies that met the inclusion criteria were retrieved. The existing evidence supports the effectiveness of Tai chi on improving quality of life (QOL) and functional balance in MS patients. A small number of these studies also reported the positive effect of Tai chi on flexibility, leg strength, gait, and pain. The effect of Tai chi on fatigue is inconsistent across studies. Although the findings demonstrate beneficial effects on improving outcome measures, especially for functional balance and QOL improvements, a conclusive claim should be made carefully for reasons such as methodological flaws, small sample size, lack of specific-disease instruments, unclear description of Tai chi protocol, unreported safety of Tai chi, and insufficient follow-up as documented by the existing literature. Future research should recruit a larger number of participants and utilize the experimental design with a long-term follow-up to ascertain the benefits of Tai chi for MS patients.

    Many people seek alternative treatments to reduce stress and to manage anxiety. To counsel people appropriately, physicians need to understand current evidence and recognize both the value and defects in the facts. To review the effect of Tai Chi interventions on improvement of mental health and to learn lessons from current evidence through various clinical studies. A literature search was performed to identify research studies that assessed Tai Chi's mental health benefits. Selected studies were classified according to research design, outcome measures, and results. They were qualitatively assessed based on Tai Chi's significant influence on mental health in the areas of mood, stress, and anxiety level. After screening in citations that mentioned Tai Chi as an intervention, we found 21 clinical studies, all of which included at least one outcome measure of mental health or a testing system that included a mental health component. Our results show low evidence of recommending Tai Chi intervention to all patients who seek improvement in mental health despite that many positive effects of Tai Chi practice on mood and anxiety were found in different clinical trials. Considering the fact that Tai Chi is a gentle exercise, well suited for people with various physical capabilities, especially the elderly, health care providers may consider recommending it to people with mental health issues and seek alternative treatment besides routine medical care. Nonetheless, clinicians should be aware of the limitations due to incomplete understanding of Tai Chi as an intervention. Better evidence and stronger clinical trial designs are needed to further investigate Tai Chi's role in improving mental health.

    Objective It remains unclear whether Tai Chi is effective for preventing falls in older adults. We undertook this systematic review to evaluate the preventive effect of Tai Chi by updating the latest trial evidence. Design Systematic review and meta-analysis. Methods The Cochrane Library, MEDLINE and EMBASE were searched up to February 2016 to identify randomised trials evaluating Tai Chi for preventing falls in older adults. We evaluated the risk of bias of included trials using the Cochrane Collaboration's tool. Results were combined using random effects meta-analysis. Outcome measures Number of fallers and rate of falls. Results 18 trials with 3824 participants were included. The Tai Chi group was associated with significantly lower chance of falling at least once (risk ratio (RR) 0.80, 95% CI 0.72 to 0.88) and rate of falls (incidence rate ratio (IRR) 0.69, 95% CI 0.60 to 0.80) than the control group. Subgroup analyses suggested that the preventive effect was likely to increase with exercise frequency (number of fallers: p=0.001; rate of falls: p=0.007) and Yang style Tai Chi was likely to be more effective than Sun style Tai Chi (number of fallers: p=0.01; rate of falls: p=0.001). The results might be influenced by publication bias as the funnel plots showed asymmetry. Sensitivity analyses by sample size, risk of bias and comorbidity showed no major influence on the primary results. Conclusions Tai Chi is effective for preventing falls in older adults. The preventive effect is likely to increase with exercise frequency and Yang style Tai Chi seems to be more effective than Sun style Tai Chi. PMID:28167744

    Full Text Available Abstract Background Low back pain persisting for longer than 3 months is a common and costly condition for which many current treatments have low-moderate success rates at best. Exercise is among the more successful treatments for this condition, however, the type and dosage of exercise that elicits the best results is not clearly defined. Tai chi is a gentle form of low intensity exercise that uses controlled movements in combination with relaxation techniques and is currently used as a safe form of exercise for people suffering from other chronic pain conditions such as arthritis. To date, there has been no scientific evaluation of tai chi as an intervention for people with back pain. Thus the aim of this study will be to examine the effects of a tai chi exercise program on pain and disability in people with long-term low back pain. Methods and design The study will recruit 160 healthy individuals from the community setting to be randomised to either a tai chi intervention group or a wait-list control group. Individuals in the tai chi group will attend 2 tai chi sessions (40 minutes/week for 8 weeks followed by 1 tai chi session/week for 2 weeks. The wait-list control will continue their usual health care practices and have the opportunity to participate in the tai chi program once they have completed the follow-up assessments. The primary outcome will be bothersomeness of back symptoms measured with a 0–10 numerical rating scale. Secondary outcomes include, self-reports of pain-related disability, health-related quality of life and global perceived effect of treatment. Statistical analysis of primary and secondary outcomes will be based on the intention to treat principle. Linear mixed models will be used to test for the effect of treatment on outcome at 10 weeks follow up. This trial has received ethics approval from The University of Sydney Human Research Ethics Committee. HREC Approval No.10452 Discussion This study will be the first

    Few remedies effectively treat long-term pain and disability from knee osteoarthritis. Studies suggest that Tai Chi alleviates symptoms, but no trials have directly compared Tai Chi with standard therapies for osteoarthritis. To compare Tai Chi with standard physical therapy for patients with knee osteoarthritis. Randomized, 52-week, single-blind comparative effectiveness trial. (ClinicalTrials.gov: NCT01258985). An urban tertiary care academic hospital. 204 participants with symptomatic knee osteoarthritis (mean age, 60 years; 70% women; 53% white). Tai Chi (2 times per week for 12 weeks) or standard physical therapy (2 times per week for 6 weeks, followed by 6 weeks of monitored home exercise). The primary outcome was Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score at 12 weeks. Secondary outcomes included physical function, depression, medication use, and quality of life. At 12 weeks, the WOMAC score was substantially reduced in both groups (Tai Chi, 167 points [95% CI, 145 to 190 points]; physical therapy, 143 points [CI, 119 to 167 points]). The between-group difference was not significant (24 points [CI, -10 to 58 points]). Both groups also showed similar clinically significant improvement in most secondary outcomes, and the benefits were maintained up to 52 weeks. Of note, the Tai Chi group had significantly greater improvements in depression and the physical component of quality of life. The benefit of Tai Chi was consistent across instructors. No serious adverse events occurred. Patients were aware of their treatment group assignment, and the generalizability of the findings to other settings remains undetermined. Tai Chi produced beneficial effects similar to those of a standard course of physical therapy in the treatment of knee osteoarthritis.

    Full Text Available Objectives. To evaluate the reporting quality of published randomized clinical trials (RCTs in the Tai Chi literature following the publication of the CONSORT guidelines in 2001. Data Sources. The OVID MEDLINE and PUBMED databases. Review Methods. To survey the general characteristics of Tai Chi RCTs in the literature, we included any report if (i it was an original report of the trial; (ii its design was RCT; (iii one of the treatments being tested was Tai Chi; and (iv it was in English. In addition, we assessed the reporting quality of RCTs that were published between 2002 and 2007, using a modified CONSORT checklist of 40 items. The adequate description of Tai Chi interventions in these trials was examined against a 10-item checklist adapted from previous reviews. Results. The search yielded 31 Tai Chi RCTs published from 2002 to 2007 and only 11 for 1992–2001. Among trials published during 2002–2007, the most adequately reported criteria were related to background, participant eligibility and interpretation of the study results. Nonetheless, the most poorly reported items were associated with randomization allocation concealment, implementation of randomization and the definitions of period of recruitment and follow-up. In addition, only 23% of RCTs provided adequate details of Tai Chi intervention used in the trials. Conclusion. The findings in this review indicated that the reporting quality of Tai Chi intervention trials is sub-optimal. Substantial improvement is required to meet the CONSORT guidelines and allow assessment of the quality of evidence. We believe that not only investigators, but also journal editors, reviewers and funding agencies need to follow the CONSORT guidelines to improve the standards of research and strengthen the evidence base for Tai Chi and for complementary and alternative medicine.

    A previous randomized, controlled trial of tai chi showed improvements in objectively measured balance and other motor-related outcomes in patients with Parkinson's disease. This study evaluated whether patient-reported outcomes could be improved through exercise interventions and whether improvements were associated with clinical outcomes and exercise adherence. In a secondary analysis of the tai chi trial, patient-reported and clinical outcomes and exercise adherence measures were compared between tai chi and resistance training and between tai chi and stretching exercise. Patient-reported outcome measures were perceptions of health-related benefits resulting from participation, assessed by the Parkinson's Disease Questionnaire (PDQ-8) and Vitality Plus Scale (VPS). Clinical outcome measures included motor symptoms, assessed by a modified Unified Parkinson's Disease Rating Scale-Motor Examination (UPDRS-ME) and a 50-foot speed walk. Information on continuing exercise after the structured interventions were terminated was obtained at a 3-month postintervention follow-up. Tai chi participants reported significantly better improvement in the PDQ-8 (-5.77 points, P = 0.014) than did resistance training participants and in PDQ-8 (-9.56 points, P tai chi, patient-reported improvement in the PDQ-8 and VPS was significantly correlated with their clinical outcomes of UPDRS-ME and a 50-foot walk, but these correlations were not statistically different from those shown for resistance training or stretching. However, patient-reported outcomes from tai chi training were associated with greater probability of continued exercise behavior than were either clinical outcomes or patient-reported outcomes from resistance training or stretching. Tai chi improved patient-reported perceptions of health-related benefits, which were found to be associated with a greater probability of exercise adherence. The findings indicate the potential of patient perceptions to drive exercise

    [Purpose] Exercise has been shown to improve cardiovascular fitness and cognitive function. Whether the inclusion of mind over exercise would increase parasympathetic control of the heart and brain activities more than general exercise at a similar intensity is not known. The aim of this study was to compare the effects of Tai Chi (mind-body exercise) versus arm ergometer cycling (body-focused exercise) on the heart rate variability and prefrontal oxygenation level. [Subjects and Methods] A Tai Chi master was invited to perform Tai Chi and arm ergometer cycling with similar exercise intensity on two separate days. Heart rate variability and prefrontal oxyhemoglobin levels were measured continuously by a RR recorder and near-infrared spectroscopy, respectively. [Results] During Tai Chi exercise, spectral analysis of heart rate variability demonstrated a higher high-frequency power as well as a lower low-frequency/high-frequency ratio than during ergometer cycling, suggesting increased parasympathetic and decreased sympathetic control of the heart. Also, prefrontal oxyhemoglobin and total hemoglobin levels were higher than those during arm ergometer exercise. [Conclusion] These findings suggest that increased parasympathetic control of the heart and prefrontal activities may be associated with Tai Chi practice. Having a "mind" component in Tai Chi could be more beneficial for older adults' cardiac health and cognitive function than body-focused ergometer cycling.

    [Purpose] The purpose of this study was to investigate the effects of Tai Chi on waist circumference and blood pressure in the elderly. The present study used a nonequivalent control group pretest-posttest design. [Subjects and Methods] Sixty-eight elderly individuals residing in J city were divided into 2 groups: 34 in the experimental group, who received Tai Chi training for 6 weeks, and 34 in the control group, who did not receive Tai Chi training. Simplified Yang style 24-form Tai Chi was used as the intervention, which was conducted for 60 minutes per session, 5 sessions per week, for a total of 6 weeks. In each session, subjects in the experimental group conducted 10 minutes of warm-up exercises, 45 minutes of Tai Chi, and 5 minutes of cool-down exercises. Waist circumference and blood pressure were measured before and after the 6-week intervention. [Results] Waist circumference and blood pressure decreased significantly after the 6-week intervention in the experimental group compared with the control group. [Conclusion] Tai Chi can be used as an effective intervention to improve waist circumference and blood pressure in the elderly.

    Tai Chi is a famous training method in China, and jogging is a popular kind of exercise both in Austria and China. Nevertheless, there is little information concerning online monitoring of biosignals during both training activities in parallel. Within the last years innovative scientific monitoring tools for evaluating features of neurocardial fitness have been developed. The goal of this study was to demonstrate heart rate and heart rate variability analysis for the first time during Tai Chi and jogging. Continuous electrocardiographic monitoring over a period of 75 minutes was performed simultaneously in two healthy volunteers using the same type of equipment (medilog AR12 systems). Two healthy persons (both male, 49 years and 52 years, respectively), both hobby sportsmen, were monitored continuously during two resting periods before and after active sport and also during Tai Chi and jogging, respectively. Data acquisition was performed without any technical problems in both subjects. Poincaré plots of sequential R-R intervals (beat to beat variability) show two ellipses of different shape and magnitude. During resting periods blood pressure effects can be clearly seen in one subject (jogging). The same effects, however reduced, are obvious in the other volunteer during Tai Chi. The present investigations during Tai Chi and jogging highlight the potential value of heart rate and heart rate variability monitoring even under difficult conditions. The innovative kind of analysis helps to show how well the human body reacts to sport, stress and recovery.

    Full Text Available This study examined the effects of Tai Chi, a low-impact mind-body movement therapy, on severity of depression, anxiety, and stress symptoms in centrally obese people with elevated depression symptoms. In total, 213 participants were randomized to a 24-week Tai Chi intervention program or a wait-list control group. Assessments were conducted at baseline and 12 and 24 weeks. Outcomes were severity of depression, anxiety, and stress symptoms, leg strength, central obesity, and other measures of metabolic symptom. There were statistically significant between-group differences in favor of the Tai Chi group in depression (mean difference = −5.6 units, P<0.001, anxiety (−2.3 units, P<0.01, and stress (−3.6 units, P<0.001 symptom scores and leg strength (1.1 units, P<0.001 at 12 weeks. These changes were further improved or maintained in the Tai Chi group relative to the control group during the second 12 weeks of follow-up. Tai Chi appears to be beneficial for reducing severity of depression, anxiety, and stress and leg strength in centrally obese people with depression symptoms. More studies with longer follow-up are needed to confirm the findings. This trial is registered with ACTRN12613000010796.

    Tai Chi, performed either seating or standing, is frequently recommended to improve various aspects of health, including balance, metabolic control, heart rate variability, sleep, or immune response. Many studies exploring mind-body interventions, both with self-reported or biologically-measured outcomes, report significant differences in outcomes among participants. However, neither the physiological or psychological mechanisms behind the variations are understood. The purpose of this study was to determine whether posturography is a useful method to assess physical skill level differences between experts and non-expert Tai Chi practitioners. While standing, participants performed a series of movements from the Tai Chi for Arthritis form based on Sun style (commencement, open/close, single whip and wave hands in cloud). Master trainers and senior trainers were considered experts; all others were considered non-experts. Body sway was assessed by the CAPS™ Professional portable computerized force platform (Vestibular Technologies, LLC.). Center of Pressure motion measures were normalized by the subject's height. While standing, the experts displayed statistically greater displacement excursion and velocity when preforming commencement and wave hands in clouds forms. The results of this pilot study indicated that posturography may be a useful method to assess the quality of Tai Chi movements and potentially link the expertise of Tai Chi practitioners to changes in health related outcomes.

    Full Text Available Background: Spectral analysis of autonomic nervous system activity can provide insight into cardiovascular function. Rate pressure product is the parameter often targeted pharmacologically to decrease the incidence of myocardial events. Aim: The purpose of this study was to investigate whether or not Tai Chi Chuan practitioners would demonstrate autonomic responses that would be more cardioprotective when compared to non-trained controls. Materials and Methods: This was a cross-sectional study that measured the autonomic responses and rate pressure product of 2 groups of subjects; a Tai Chi Chuan trained (n = 13 and non-trained sedentary controls (n = 13 at rest and during 2 stressor phases that simulated functional activities of daily living. Results: The Tai Chi group maintained a greater parasympathetic outflow at rest and during the isometric grip stressor phase (P<0.05. Sympathetic outflow, systolic blood pressure and rate pressure product were significantly lower in the Tai Chi group at rest, during the isometric grip and standing stressor phases (P<0.05. Conclusion: Although a cause-and-effect relationship cannot be concluded in this study, the Tai Chi group was able to demonstrate efficiency of the myocardium with suppressed rate pressure product values and autonomic responses that favored parasympathetic outflow. This type of training may complement non-pharmacological anti-hypertensive therapy.

    This study examined factors affecting adherence in a 16-week tai chi program among multi-ethnic middle-aged and older adults living in a low socioeconomic environment in Toronto. Analysis was based on data collected from three tai chi program cohorts that took place from August 2009 to March 2012. The main outcome variable, adherence, was measured by the total number of sessions attended by each of the participants. Total sample size was 210 participants with a mean age of 68.1 ± 8.6. Based on the regression model, greater adherence was significantly associated with older age, greater perceived stress, higher education, and higher mental and physical scores of Short Form-36 components. Conversely, lower adherence was significantly associated with higher baseline weekly physical activity. Our findings suggest that we target less-educated individuals with poor mental and physical health to optimize adherence for future community-based tai chi programs.

    Full Text Available Abstract Background Knee Osteoarthritis (KOA is a major cause of pain and functional impairment among elders. Currently, there are neither feasible preventive intervention strategies nor effective medical remedies for the management of KOA. Tai Chi, an ancient Chinese mind-body exercise that is reported to enhance muscle function, balance and flexibility, and to reduce pain, depression and anxiety, may safely and effectively be used to treat KOA. However, current evidence is inconclusive. Our study examines the effects of a 12-week Tai Chi program compared with an attention control (wellness education and stretching on pain, functional capacity, psychosocial variables, joint proprioception and health status in elderly people with KOA. The study will be completed by July 2009. Methods/Design Forty eligible patients, age > 55 yr, BMI ≤ 40 kg/m2 with tibiofemoral osteoarthritis (American College of Rheumatology criteria are identified and randomly allocated to either Tai Chi (10 modified forms from classical Yang style Tai Chi or attention control (wellness education and stretching. The 60-minute intervention sessions take place twice weekly for 12 weeks. The study is conducted at an urban tertiary medical center in Boston, Massachusetts. The primary outcome measure is the Western Ontario and McMaster Universities (WOMAC pain subscale at 12 weeks. Secondary outcomes include weekly WOMAC pain, function and stiffness scores, patient and physician global assessments, lower-extremity function, knee proprioception, depression, self-efficacy, social support, health-related quality of life, adherence and occurrence of adverse events after 12, 24 and 48 weeks.

    Tai Chi and Qigong are traditional Chinese exercises that are widely practiced for their health benefits and as martial arts. Evidence suggests that these practices may be effective at treating a range of physical health conditions, and at improving health-related quality of life. There is growing interest in the use of Tai Chi and Qigong to treat mental disorders, because they are noninvasive, exercise-based therapies, and because patients with mental disorders frequently use complementary and alternative medicine. Evidence is promising that these treatments may be effective in reducing depressive symptoms, stress, anxiety, and mood disturbances. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Background. This cross-sectional study examined the effect of aging on performing finger-pointing tasks involving choices and whether experienced older Tai Chi practitioners perform better than healthy older controls in such tasks. Methods. Thirty students and 30 healthy older controls were compared with 31 Tai Chi practitioners. All the subjects performed a rapid index finger-pointing task. The visual signal appeared randomly under 3 conditions: (1 to touch a black ball as quickly and as accurately as possible, (2 not to touch a white ball, (3 to touch only the white ball when a black and a white ball appeared simultaneously. Reaction time (RT of anterior deltoid electromyogram, movement time (MT from electromyogram onset to touching of the target, end-point accuracy from the center of the target, and the number of wrong movements were recorded. Results. Young students displayed significantly faster RT and MT, achieving significantly greater end-point accuracy and fewer wrong movements than older controls. Older Tai Chi practitioners had significantly faster MT than older controls. Conclusion. Finger-pointing tasks with a choice paradigm became slower and less accurate with age. Positive findings suggest that Tai Chi may slow down the aging effect on eye-hand coordination tasks involving choices that require more cognitive progressing.

    Tai Chi and Qigong (TCQG) show promise for improving many health outcomes and are recommended for dissemination to older adults. A simplified, easy-to-replicate version of TCQG, "Tai Chi Easy," was tested using a train-the-trainer method to demonstrate feasibility of dissemination to a widespread population of older adults through community sites and achievement of perceived outcomes. Nonexpert facilitators known as "practice leaders" were trained to implement Tai Chi Easy sessions at 18 sites across the United States. Outstanding facilitator (100%) and participant (94%) adherence was achieved. With 330 completers, mean age 73 years, significant improvements were found for participants' perceived stress levels (P = .003). Sleep quality and energy/vitality were markedly improved. Eighty-nine percent enjoyed the program, 91% were committed to continue, and 67% stated that they had increased their weekly levels of physical activity. A train-the-facilitator model for Tai Chi Easy is easily disseminated to older adults and may promote a sustainable alternative exercise, yielding favorable quality of life benefits.

    The poor health consequences of stress are well recognized, and students in higher education may be at particular risk. Tai Chi integrates physical exercise with mindfulness techniques and seems well suited to relieve stress and related conditions. We conducted a systematic review of the health benefits of Tai Chi for students in higher education reported in the English and Chinese literature, using an evidence hierarchy approach, allowing the inclusion of studies additional to randomized controlled trials. Sixty eight reports in Chinese and 8 in English were included - a combined study sample of 9263 participants. Eighty one health outcomes were extracted from reports, and assigned evidence scores according to the evidence hierarchy. Four primary and eight secondary outcomes were found. Tai Chi is likely to benefit participants by increasing flexibility, reducing symptoms of depression, decreasing anxiety, and improving interpersonal sensitivity (primary outcomes). Secondary outcomes include improved lung capacity, balance, 800/1000m run time, quality of sleep, symptoms of compulsion, somatization and phobia, and decreased hostility. Our results show Tai Chi yields psychological and physical benefits, and should be considered by higher education institutions as a possible means to promote the physical and psychological well-being of their students.

    Moderate-intensity exercise has attracted considerable attention because of its safety and many health benefits. Tai Chi, a form of mind-body exercise that originated in ancient China, has been gaining popularity. Practicing Tai Chi may improve overall health and well-being; however, to our knowledge, no study has evaluated its relationship with mortality. We assessed the associations of regular exercise and specifically participation in Tai Chi, walking, and jogging with total and cause-specific mortality among 61,477 Chinese men in the Shanghai Men's Health Study (2002-2009). Information on exercise habits was obtained at baseline using a validated physical activity questionnaire. Deaths were ascertained through biennial home visits and linkage with a vital statistics registry. During a mean follow-up of 5.48 years, 2,421 deaths were identified. After adjustment for potential confounders, men who exercised regularly had a hazard ratio for total mortality of 0.80 (95% confidence interval: 0.74, 0.87) compared with men who did not exercise. The corresponding hazard ratios were 0.80 (95% confidence interval: 0.72, 0.89) for practicing Tai Chi, 0.77 (95% confidence interval: 0.69, 0.86) for walking, and 0.73 (95% confidence interval: 0.59, 0.90) for jogging. Similar inverse associations were also found for cancer and cardiovascular mortality. The present study provides the first evidence that, like walking and jogging, practicing Tai Chi is associated with reduced mortality.

    Full Text Available Abstract Background Physical activity and exercise appear to improve psychological health. However, the quantitative effects of Tai Chi on psychological well-being have rarely been examined. We systematically reviewed the effects of Tai Chi on stress, anxiety, depression and mood disturbance in eastern and western populations. Methods Eight English and 3 Chinese databases were searched through March 2009. Randomized controlled trials, non-randomized controlled studies and observational studies reporting at least 1 psychological health outcome were examined. Data were extracted and verified by 2 reviewers. The randomized trials in each subcategory of health outcomes were meta-analyzed using a random-effects model. The quality of each study was assessed. Results Forty studies totaling 3817 subjects were identified. Approximately 29 psychological measurements were assessed. Twenty-one of 33 randomized and nonrandomized trials reported that 1 hour to 1 year of regular Tai Chi significantly increased psychological well-being including reduction of stress (effect size [ES], 0.66; 95% confidence interval [CI], 0.23 to 1.09, anxiety (ES, 0.66; 95% CI, 0.29 to 1.03, and depression (ES, 0.56; 95% CI, 0.31 to 0.80, and enhanced mood (ES, 0.45; 95% CI, 0.20 to 0.69 in community-dwelling healthy participants and in patients with chronic conditions. Seven observational studies with relatively large sample sizes reinforced the beneficial association between Tai Chi practice and psychological health. Conclusions Tai Chi appears to be associated with improvements in psychological well-being including reduced stress, anxiety, depression and mood disturbance, and increased self-esteem. Definitive conclusions were limited due to variation in designs, comparisons, heterogeneous outcomes and inadequate controls. High-quality, well-controlled, longer randomized trials are needed to better inform clinical decisions.

    Gait dysfunction and postural instability are two debilitating symptoms in persons with Parkinson's disease (PD). Tai Chi exercise has recently gained attention as an attractive intervention for persons with PD because of its known potential to reduce falls and improve postural control, walking abilities, and safety at a low cost. The purpose of this report is to investigate the effect of Tai Chi exercise on dynamic postural control during gait initiation and gait performance in persons with idiopathic PD, and to determine whether these benefits could be replicated in two different environments, as complementary projects. In these two separate projects, a total of 45 participants with PD were randomly assigned to either a Tai Chi group or a control group. The Tai Chi groups in both projects completed a 16-week Tai Chi exercise session, while the control groups consisted of either a placebo (i.e., Qi-Gong) or non-exercise group. Tai Chi did not significantly improve Unified Parkinson's Disease Rating Scale Part III score, selected gait initiation parameters or gait performance in either project. Combined results from both projects suggest that 16 weeks of class-based Tai Chi were ineffective in improving either gait initiation, gait performance, or reducing parkinsonian disability in this subset of persons with PD. Thus the use of short-term Tai Chi exercise should require further study before being considered a valuable therapeutic intervention for these domains in PD.

    The particle paths of the Lagrangian flow field simulate very well the interface curve of the Yin-Yang balance in the ancient Tai-Chi diagram. There are four forms called the "four states" in the Tai-Chi diagram. Of the four states, under Yang are the Major Yang and the Minor Yin, and under Yin are the Major Yin and the Minor Yang. The present study provides the proper positions of the four states in the ancient Tai-Chi diagram. The Fu Xi's Eight Trigrams Chart located along the ancient Tai-Chi diagram is also developed in the present study. The interface curve of Yin-Yang in the ancient Tai-Chi diagram has never been described mathematically. It can now be formulated by the equations describing the particle paths in the Lagrangian flow field.

    This study examined the effects of regular Tai Chi practice and jogging on the neuromuscular activity of the trunk, hip, and ankle joint muscles of older people during lateral postural perturbation. A total of 42 older people participated in the study and formed the Tai Chi, jogging, and sedentary control groups. Electromyography signals were collected from the peroneus longus, anterior tibialis, gluteus medius, and erector spinae during unpredictable mediolateral perturbation. The Tai Chi group exhibited significantly faster latencies of the tibialis anterior and erector spinae than the control group. The jogging group showed a significantly shorter neuromuscular reaction time of the erector spinae than the control group. No significant difference was observed between the Tai Chi and jogging groups. Long-term regular Tai Chi practice enhanced the neuromuscular reaction of the erector spinae and tibialis anterior to lateral perturbation and will help timely posture correction when lateral postural distributions occur.

    Tai chi exercise may have positive effects on bone health in perimenopausal and postmenopausal women. This systematic review is the first to summarize evidence to clarify the efficacy of tai chi exercise in bone health. The benefits of tai chi exercise on bone health remain unclear; further studies are needed. Emerging randomized controlled trials (RCTs) exploring the efficacy of tai chi exercise on bone health among older women, but yielded inconclusive results. Our objective is to conduct a systematic review to evaluate evidence from RCTs to clarify the efficacy of tai chi exercise on bone mineral density (BMD), and bone turnover markers (BTM) in perimenopausal and postmenopausal women. Six electronic databases were searched, and reference lists of systematic reviews and identified studies from the search strategy were also screened. We included all RCTs that investigate tai chi exercise for bone health in perimenopausal and postmenopausal women. Data selection, extraction, and evaluation of risk of bias were performed independently by two reviewers. Ten trials detailed in 11 articles were included. Six of the 11 studies reported positive outcomes on bone health. Results of our meta-analysis showed a significant effect of tai chi exercise on BMD change at the spine compared with no treatment in perimenopausal and postmenopausal women. When tai chi exercise combined with a calcium supplement was compared with the calcium supplement alone, the result of BMD change at the spine showed no significant effect. Because the measurable effect observed was minimal, and due to the low quality of methodology of the studies, we conclude that the result is of limited reliability. Tai chi exercise may have benefits on bone health in perimenopausal and postmenopausal women, but the evidence is sometimes weak, poor, and inconsistent. Consequently, only limited conclusions can be drawn regarding the efficacy of tai chi exercise on bone health. Further well designed studies with

    Cystic fibrosis (CF) is a genetic disorder affecting respiratory and digestive systems. People with CF experience physical symptoms; cough, poor lung ventilation, recurrent infections, poor weight gain, diarrhoea, and malnutrition, as well as lower quality of life. Tai Chi, a Chinese form of meditative movement, may help with the symptoms of CF and help people with CF to exercise. However, there is very little research in this area. To evaluate the feasibility of studying Tai Chi for CF and to compare the effectiveness of Tai Chi to standard care and face-to-face Tai Chi with online Tai Chi for people with CF. This is a comparative effectiveness trial with 72 people with CF over 6 years old and a patient at the Royal Brompton Hospital, London, UK. Participants receive 8 Tai Chi sessions, then home practice with a DVD. Sessions are one-on-one for group A, online for group B. Group B is a no treatment standard care control (first 3 months). At baseline, 3, 6 and 9 months, questionnaires will be used to measure quality of life, mindfulness and sleep, and medical data health and respiratory function. At Tai Chi sessions and at 4 follow-up points, the Borg Scale and healthcare use data will be collected. At 9 months online focus groups will assess participants' experience, Tai Chi feasibility, perceived health impact, and study participation. Recruitment will use adverts in hospital clinics and website, and letter/phone for non-regularly attending patients. Block randomisation will use random number tables. The two groups will be compared for: weeks 1 to 12 (Tai Chi vs. standard care); before and after intervention (differences in delivery method); week 1 (of intervention) to month 9 (long-term impact). Qualitative data will use Framework analysis. We believe this is the first trial of Tai Chi for CF. Tai Chi may help with the physiological symptoms of CF and increase levels of exercise by providing a self-management technique and low stress activity. This study will

    This article provides a description of a clinical project that used combined Tai Chi and mindfulness-based stress reduction as an educational program. The 5-week program demonstrated that sustained interest in this material in middle school-aged boys and girls is possible. Statements the boys and girls made in the process suggested that they experienced well-being, calmness, relaxation, improved sleep, less reactivity, increased self-care, self-awareness, and a sense of interconnection or interdependence with nature. The curriculum is described in detail for nurses, teachers, and counselors who want to replicate this type of instruction for adolescent children. This project infers that Tai Chi and mindfulness-based stress reduction may be transformational tools that can be used in educational programs appropriate for middle school-aged children. Recommendations are made for further study in schools and other pediatric settings.

    Full Text Available Objective. Patients with schizophrenia residing at institutions often suffer from negative symptoms, motor, and functional impairments more severe than their noninstitutionalized counterparts. Tai-chi emphasizes body relaxation, alertness, and movement coordination with benefits to balance, focus, and stress relief. This pilot study explored the efficacy of Tai-chi on movement coordination, negative symptoms, and functioning disabilities towards schizophrenia. Methods. A randomized waitlist control design was adopted, where participants were randomized to receive either the 6-week Tai-chi program and standard residential care or only the latter. 30 Chinese patients with schizophrenia were recruited from a rehabilitation residency. All were assessed on movement coordination, negative symptoms, and functional disabilities at baseline, following intervention and 6 weeks after intervention. Results. Tai-chi buffered from deteriorations in movement coordination and interpersonal functioning, the latter with sustained effectiveness 6 weeks after the class was ended. Controls showed marked deteriorations in those areas. The Tai-chi group also experienced fewer disruptions to life activities at the 6-week maintenance. There was no significant improvement in negative symptoms after Tai-chi. Conclusions. This study demonstrated encouraging benefits of Tai-chi in preventing deteriorations in movement coordination and interpersonal functioning for residential patients with schizophrenia. The ease of implementation facilitates promotion at institutional psychiatric services.

    The effects of long-term Tai Chi exercise on body stability of the elderly during stair ascent under high and low illumination were investigated. Forty-five healthy elderly women were divided into three groups, namely, Tai Chi exercise group, brisk walking group and no-exercise control group. All the participants ascended a staircase, during which force platforms and a motion capture system collected the data. Under the high illumination, Tai Chi exercise participants exhibited higher loading rate and anteroposterior centre of pressure (COPap) displacement as well as a lower braking impulse than no-exercise group. Under the low illumination, Tai Chi exercise participants demonstrated higher COPap and mediolateral centre of pressure (COPml) displacements as well as lower braking and lateral impulses compared with no-exercise participants. The centre of mass (COM)ml sway in Tai Chi and no exercise participants were higher, the loading rates in Tai Chi and walking participants were higher, and the lateral impulse in no exercise participants was higher under low illumination than under high illumination. Thus, low illumination increases the risk of falling. Tai Chi participants increased their foot clearance, head inclination angle and COPap displacement under low illumination to increase their stability during stair ascent.

    We report the first controlled study of Tai Chi effects on the P300 event-related potential, a neuroelectric index of human executive function. Tai Chi is a form of exercise and moving meditation. Exercise and meditation have been associated with enhanced executive function. This cross-sectional, controlled study utilized the P300 event-related potential (ERP) to compare executive network neural function between self-selected long-term Tai Chi, meditation, aerobic fitness, and sedentary groups. We hypothesized that because Tai Chi requires moderate aerobic and mental exertion, this group would show similar or better executive neural function compared to meditation and aerobic exercise groups. We predicted all health training groups would outperform sedentary controls. Fifty-four volunteers (Tai Chi, n=10; meditation, n=16; aerobic exercise, n=16; sedentary, n=12) were tested with the Rockport 1-mile walk (estimated VO2 Max), a well-validated measure of aerobic capacity, and an ecologically valid visuo-spatial, randomized, alternating runs Task Switch test during dense-array electroencephalographic (EEG) recording. Only Tai Chi and meditation plus exercise groups demonstrated larger P3b ERP switch trial amplitudes compared to sedentary controls. Our results suggest long-term Tai Chi practice, and meditation plus exercise may benefit the neural substrates of executive function.

    This study aimed to test the efficacy of Tai Chi for treating chronic neck pain. Subjects with chronic nonspecific neck pain were randomly assigned to 12 weeks of group Tai Chi or conventional neck exercises with weekly sessions of 75 to 90 minutes, or a wait-list control. The primary outcome measure was pain intensity (visual analogue scale). Secondary outcomes included pain on movement, functional disability, quality of life, well-being and perceived stress, postural and interoceptive awareness, satisfaction, and safety. Altogether, 114 participants were included (91 women, 49.4 ± 11.7 years of age). After 12 weeks Tai Chi participants reported significantly less pain compared with the wait list group (average difference in mm on the visual analogue scale: -10.5; 95% confidence interval, -20.3 to -.9; P = .033). Group differences were also found for pain on movement, functional disability, and quality of life compared with the wait list group. No differences were found for Tai Chi compared with neck exercises. Patients' satisfaction with both exercise interventions was high, and only minor side effects were observed. Tai Chi was more effective than no treatment in improving pain in subjects with chronic nonspecific neck pain. Because Tai Chi is probably as effective as neck exercises it may be considered a suitable alternative to conventional exercises for those with a preference toward Tai Chi. This article presents results of a randomized controlled trial comparing Tai Chi, conventional neck exercises, and no treatment for chronic nonspecific neck pain. Results indicate that Tai Chi exercises and conventional neck exercises are equally effective in improving pain and quality of life therefore representing beneficial interventions for neck pain.

    The primary objective of this study was to provide preliminary evaluation of the feasibility, safety, and efficacy of a newly developed Tai Chi-based exercise program for older adults with Parkinson's disease (PD). Using a one-group pretest-posttest design, 17 community-dwelling adults (mean age 71.51 years) with mild to moderate idiopathic PD (Stage I, II, or III on the Hoehn and Yahr scale) and stable medication use completed a 5-day, 90-min/day Tai Chi exercise-evaluation program. Outcome measures included face-to-face exit interviews on appropriateness and safety and physical performance (i.e., 50-ft speed walk, up-and-go, functional reach). At the end of this brief intervention, exercise adherence was 100% and the program was shown to be safe. Exit interviews indicated that the program was well received by all participants with respect to program appropriateness, participant satisfaction and enjoyment, and intentions to continue. Furthermore, a significant pretest-to-posttest change was observed at the end of the 5-day program in all three physical-performance measures (p Tai Chi is an appropriate physical activity for older adults with PD and might also be useful as a therapeutic exercise modality for improving and maintaining physical function. These preliminary findings warrant further investigation.

    Full Text Available Background: Several studies have shown that Tai Chi Chuan can improve cardiac function in patients with heart disease. Objective: To conduct a systematic review of the literature to assess the effects of Tai Chi Chuan on cardiac rehabilitation for patients with coronary artery disease. Methods: We performed a search for studies published in English, Portuguese and Spanish in the following databases: MEDLINE, EMBASE, LILACS and Cochrane Register of Controlled Trials. Data were extracted in a standardized manner by three independent investigators, who were responsible for assessing the methodological quality of the manuscripts. Results: The initial search found 201 studies that, after review of titles and abstracts, resulted in a selection of 12 manuscripts. They were fully analyzed and of these, nine were excluded. As a final result, three randomized controlled trials remained. The studies analyzed in this systematic review included patients with a confirmed diagnosis of coronary artery disease, all were clinically stable and able to exercise. The three experiments had a control group that practiced structured exercise training or received counseling for exercise. Follow-up ranged from 2 to 12 months. Conclusion: Preliminary evidence suggests that Tai Chi Chuan can be an unconventional form of cardiac rehabilitation, being an adjunctive therapy in the treatment of patients with stable coronary artery disease. However, the methodological quality of the included articles and the small sample sizes clearly indicate that new randomized controlled trials are needed in this regard.

    Full Text Available In order to promote the scientific standardization of Tai-chi-chuan teaching and training, a Tai-chi-chuan auxiliary training system based on Kinect motion capture technology and extraction of the angle feature and speed feature is proposed and designed. The dynamic time planning algorithm (DTW sampling corresponding frame is applied to replace the traditional method of sampling the key frame. The auxiliary training system consists of learning module, action acquisition module and action scoring module. Learning module with stan-dard action teaching video, to meet the requirements of students learning; action acquisition module uses Microsoft developed Kinect equipment to realize data acquisition of the spatial coordinates of the human skeleton in Tai-chi-chuan action, and through filtered noise reduction and the occlusion point data processing the skeleton data is saved. The scoring module constructs the test sequence based on the 16 angle features of eight key joint nodes and the instantaneous velocity characteristics of 20 joint nodes. By comparing with the standard sequence in real time, the original scoring rules is used to achieve the scoring function, which provides students with intuitive and reliable training recommendations, so as to improve the efficiency of learning. By increasing the number of sensors, further designing and optimizing data fusion and filtering algorithm, combining with Microsoft’s Kinect2.0 version, the system can also be applied to medical rehabilitation, physical training analysis and evaluation, virtual reality and human-computer interaction, etc.

    Recent dual-task studies suggest that Tai Chi practitioners displayed better control of standing posture and maintained a quicker response time of postural muscle activation during a stepping down activity. Whether this effect extends to voluntary balance control, specifically the limits of excursion of the center of pressure, remains to be examined. The purpose of this study was to evaluate the cognitive-motor interference pattern by examining the effects of a concurrently performed cognitive task on attention of voluntary balance control in older adults who are long-term practitioners of Tai Chi. Ten older Tai Chi practitioners and 10 age-matched nonpractitioners performed a voluntary balance task that required them to shift their weight to reach a preset target in the forward and backward directions, with (single task, ST) and without (dual task, DT) a secondary cognitive task, which was the counting backward task. The counting backward task required the individual to compute and verbalize a series of arithmetic differences between a given pair of randomly generated numbers. The cognitive task was also performed independently (cognitive-ST). All trials were performed in a random order. Balance outcomes included reaction time, movement velocity, and maximal excursion of the center of pressure provided by the NeuroCom system. Cognitive outcome was the number of correct responses generated within the 8-second trial during the ST and DT conditions. Outcome variables were analyzed using a 2-factor, group by task, analysis of variance. DT costs for the variables were calculated as the relative difference between ST and DT conditions and were compared between the 2 groups using independent t tests. Tai Chi practitioners displayed shorter reaction times (P motor and cognitive resources than older nonpractitioners during a fairly complex (dynamic) postural equilibrium task while performing a verbal working memory task. They exhibited lesser cognitive-motor interference

    To determine whether Tai Chi Chuan or ballroom dancing promotes better performance with respect to postural balance, gait, and postural transfer among elderly people. We evaluated 76 elderly individuals who were divided into two groups: the Tai Chi Chuan Group and the Dance Group. The subjects were tested using the NeuroCom Balance Master¯ force platform system with the following protocols: static balance tests (the Modified Clinical Tests of Sensory Interaction on Balance and Unilateral Stance) and dynamic balance tests (the Walk Across Test and Sit-to-stand Transfer Test). In the Modified Clinical Test of Sensory Interaction on Balance, the Tai Chi Chuan Group presented a lower sway velocity on a firm surface with open and closed eyes, as well as on a foam surface with closed eyes. In the Modified Clinical Test of Sensory Interaction on Unilateral Stance, the Tai Chi Chuan Group presented a lower sway velocity with open eyes, whereas the Dance Group presented a lower sway velocity with closed eyes. In the Walk Across Test, the Tai Chi Chuan Group presented faster walking speeds than those of the Dance Group. In the Sit-to-stand Transfer Test, the Tai Chi Chuan Group presented shorter transfer times from the sitting to the standing position, with less sway in the final standing position. The elderly individuals who practiced Tai Chi Chuan had better bilateral balance with eyes open on both types of surfaces compared with the Dance Group. The Dance Group had better unilateral postural balance with eyes closed. The Tai Chi Chuan Group had faster walking speeds, shorter transfer times, and better postural balance in the final standing position during the Sit-to-stand Test.

    Observe the effect of Tai Chi in combination with auricular plaster therapy on treating obesity patient with secondary hyperlipidemia. Select 45 patients who suffer from simple obesity and secondary hyperlipidemia and then adopt random digital table to divide them into a Tai Chi group, an auricular plaster therapy group and a combination group. Each group consists of 15 patients. The patients in Tai Chi group are trained with Tai Chi twice a day, while those in auricular plaster therapy are treated with auricular plaster therapy 3-5 times a day and those in the combination group are trained with Tai Chi and auricular plaster therapy twice a day. BMI, body fat percentage and blood lipid indexes are respectively detected for the selected patients in the three groups before treatment and after 180 days' treatment. After 180 days' treatment, BMI index and body fat percentage of Tai Chi group are significantly improved in comparison with those before treatment (Pplaster therapy group are not improved obviously in comparison with those before the treatment (P>0.05) but the blood lipid index is improved significantly (Pplaster therapy can show the obvious synergistic therapeutic effect and thus the combined curative effect is obviously superior to that of the single therapy method.

    Several studies reported that Tai Chi showed potential effects for chronic pain, but its role remains controversial. This review assessed the evidence regarding the effects of Tai Chi for chronic pain conditions. 18 randomized controlled trials were included in our review. The aggregated results have indicated that Tai Chi showed positive evidence on immediate relief of chronic pain from osteoarthritis (standardized mean difference [SMD], -0.54; 95% confidence intervals [CI], -0.77 to -0.30; P Tai Chi practice for osteoarthritis may be more than 5 weeks. And there were some beneficial evidences regarding the effects of Tai Chi on immediate relief of chronic pain from low back pain (SMD, -0.81; 95% CI, -1.11 to -0.52; P osteoporosis (SMD, -0.83; 95% CI, -1.37 to -0.28; P = 0.003). Therefore, clinicians may consider Tai Chi as a viable complementary and alternative medicine for chronic pain conditions.

    Objective. The purpose of this systematic review is to evaluate the evidence on the effect of Tai Chi for Parkinson's disease (PD). Methods. Six electronic databases up to June 2014 were searched. The methodological quality was assessed with PEDro scale. Standardised mean difference and 95% confidence intervals of random-effects model were calculated. Results. Nine studies were included in our review. The aggregated results are in favor of Tai Chi on improving motor function (P = 0.002) and balance (P Tai Chi on improving gait velocity (P = 0.11), stride length (P = 0.21), or quality of life (P = 0.40). And there is no valid evidence in follow-up effects of Tai Chi for PD. Conclusion. The current results suggest that Tai Chi can significantly improve the motor function and balance in patients with PD, but there is indeed not enough evidence to conclude that Tai Chi is effective for PD because of the small treatment effect, methodological flaws of eligible studies, and insufficient follow-up. Consequently, high-quality studies with long follow-up are warranted to confirm current beneficial findings.

    Full Text Available The aim of this study was to determine whether performing Tai Chi Chuan on a customized vibration platform could enhance balance control and lower extremity muscle power more efficiently than Tai Chi Chuan alone in an untrained young population. Forty-eight healthy young adults were randomly assigned to the following three groups: a Tai Chi Chuan combined with vibration training group (TCV, a Tai Chi Chuan group (TCC or a control group. The TCV group underwent 30 minutes of a reformed Tai Chi Chuan program on a customized vibration platform (32 Hz, 1 mm three times a week for eight weeks, whereas the TCC group was trained without vibration stimuli. A force platform was used to measure the moving area of a static single leg stance and the heights of two consecutive countermovement jumps. The activation of the knee extensor and flexor was also measured synchronously by surface electromyography in all tests. The results showed that the moving area in the TCV group was significantly decreased by 15.3%. The second jump height in the TCV group was significantly increased by 8.14%, and the activation of the knee extensor/flexor was significantly decreased in the first jump. In conclusion, Tai Chi Chuan combined with vibration training can more efficiently improve balance control, and the positive training effect on the lower extremity muscle power induced by vibration stimuli still remains significant because there is no cross-interaction between the two different types of training methods.

    Full Text Available Tai chi exercise has been recommended as suitable for the improvement of health in the elderly. The purpose of this study was to investigate the effects of tai chi on lower urinary tract symptoms (LUTSs, quality of life (QoL, and sex hormone levels in patients with benign prostate hypertrophy (BPH. The elderly patients with BPH were randomized to receive tai chi or usual care. Fifty-six participants were randomized into either the tai chi group (n=28 or the control group (n=28. After 12 weeks of treatment, the tai chi group showed significant improvement in LUTS and QoL. There was a significant effect of tai chi on testosterone but no significant effect on insulin or glucose. No serious adverse events were observed during the study period. In conclusion, our results suggest that 12 weeks of tai chi may improve LUTS and QoL in elderly patients with BPH.

    Though previous research has shown that Tai Chi reduces falls risk in older adults, no studies have examined underlying neural mechanisms responsible for balance improvement. We aimed to determine the efficacy of Tai Chi training in improving neuromuscular response characteristics underlying balance control in balance-impaired older adults. Twenty-two balance-impaired older adults were randomly divided into Tai Chi (TC) or control groups. Nineteen subjects (age 68-92, BERG 44 or less) completed the study. TC training included repetitive exercises using TC motor and biomechanical strategies, techniques, and postural elements. Control training included axial mobility exercises, balance/awareness education and stress reduction. Groups trained 1.5 hours/day, 5 days/week for 3 weeks. After post-testing the control group received TC training. Subjects walked across a force plate triggered to move forward 15 cm at 40 cm/sec at heel strike. Tibialis anterior (TA) and medial gastrocnemius (GA) responses during balance recovery were measured with electromyograms (EMGs). Four clinical measures of balance were also recorded. TC subjects, but not controls, significantly reduced both TA response time from 148.92 +/- 45.11 ms to 98.67 +/- 17.22 ms (p < or = 0.004) and occurrence of co-contraction of antagonist muscles (p < or = 0.003) of the perturbed leg. Clinical balance measures also significantly improved after TC. TC enhanced neuromuscular responses controlling the ankle joint of the perturbed leg. Fast, accurate neuromuscular activation is crucial for efficacious response to slips or trips.

    Workplace computer use has increased dramatically in recent years and has been linked to musculoskeletal disorders, a leading cause of work disability and productivity losses in industrialized nations. Tai Chi is a simple, convenient workplace intervention that may promote musculoskeletal health without special equipment or showering, yet no study has investigated Tai Chi as a workplace physical exercise for health promotion. To examine the effects of a workplace Tai Chi (TC) intervention on musculoskeletal fitness and psychological well-being among female university employees who are computer users. The exercise program consisted of two 50 minute TC classes per week for 12 consecutive weeks during the months of May-August 2007. Fifty-two participants were enrolled in a class conducted on campus by a professional TC practitioner during the lunch hour. Socio-demographic characteristics, including information on age, marital status, ethnicity, job category and perceived overall health were collected from all participants. Fitness testing conducted by qualified personnel was assessed pre- and post-program. The tests included resting heart rate, resting blood pressure, anthropometric measures, musculoskeletal fitness and back fitness. Psychological well-being was assessed by the Perceived Stress Scale pre- and post-program. There were significant positive results in several areas including resting heart rate, waist circumference and hand grip strength. Results showed that the TC program was effective in improving musculoskeletal fitness and psychological well-being. Significant improvements in physiological and psychological measures were observed, even at the large class sizes tested here, suggesting that TC has considerable potential as an economic, effective and convenient workplace intervention.

    Full Text Available Introduction Asian natural health practices are increasingly present in the physical and sporting habits of the Western population. In particular, the Tai Chi Chuan (TCC and Qigong (QG have become an everyday activity that can be performed both in parks and sports facilities in Western cities. The impact of these activities on a global level is very difficult to measure, however, given the lack of statistics on the number of practitioners, associations and existing schools. The degree of acceptance that these disciplines have achieved can be measured by the number of informative publications about them. According to the study by Perez and Gutierrez (2008, 215 (62.3 % of the 345 papers published between 1960 and 2006 on Chinese martial arts were on QG, and 115 (33.3 % papers were on TCC, implying that both practices represented 95.6 percent of these publications. More importantly, during the 1990-1999 and 2000-2006 time periods, TCC came to occupy the top of monographs published, ahead of the rest of all forms of Chinese, Japanese and Korean martial arts; during the last time period, QG represented the third most published. According to the authors, the rise of this activity can be attributed to motivation changes for sports. Health, personal development, education, and socialization, as opposed to competition, have become increasingly important goals, which both TCC and QG fit perfectly.

    This systematic review aimed to critically appraise published clinical trials designed to assess the effect of Tai Chi on psychosocial well-being. Databases searched included MEDLINE, CINAHL, EMBASE, HEALT, PsycINFO, CISCOM, the Cochrane Central Register of Controlled Trials of the Cochrane Library, and dissertations and conference proceedings from inception to August 2008. Methodological quality was assessed using a modified Jadad scale. A total of 15 studies met the inclusion criteria (i.e. English publications of randomized controlled trials with Tai Chi as an intervention and psychological well-being as an outcome measure), of which eight were high quality trials. The psychosocial outcomes measured included anxiety (eight studies), depression (eight studies), mood (four studies), stress (two studies), general mental health three studies), anger, positive and negative effect, self-esteem, life satisfaction, social interaction and self-rated health (one study each). Tai Chi intervention was found to have a significant effect in 13 studies, especially in the management of depression and anxiety. Although the results seemed to suggest Tai Chi is effective, they should be interpreted cautiously as the quality of the trials varied substantially. Furthermore, significant findings were shown in only six high quality studies. Moreover, significant between group differences after Tai Chi intervention was demonstrated in only one high quality study (the other three significant results were observed in non-high quality studies). Two high quality studies in fact found no significant Tai Chi effects. It is still premature to make any conclusive remarks on the effect of Tai Chi on psychosocial well-being.

    The chronic and prevalent natures of schizophrenia result in long-term institutionalization for the patients. Conventional treatment of anti-psychotic medication on management of psychotic symptoms often brings on severe side effects and reduces patients' well-being. Tai-chi is a mind-body exercise that underscores motor coordination and relaxation. This 3-arm randomized controlled trial investigated the psychophysiological benefits of Tai-chi on 153 chronic schizophrenia patients, who were recruited from a mental health rehab complex and randomized into Tai-chi, exercise, or waitlist control groups. Both intervention groups received 12weeks of specific intervention plus standard medication received by the controls. All participants completed psychiatric interviews, self-report questionnaires, performance tasks, and salivary cortisol measures at baseline, 3-month, and 6-month follow-up on psychotic symptoms, motor coordination, memory, daily living function, and stress. Multigroup latent growth modeling was used to evaluate the intervention effects on the outcomes. Compared to controls, the Tai-chi group showed significant decreases in motor deficits and increases in backward digit span and mean cortisol, while the exercise group displayed significant decreases in motor deficits, negative and depression symptoms and increases in forward digit span, daily living function, and mean cortisol. The two interventions did not show significantly different therapeutic effects, except for fewer symptom manifestations in the exercise group. These results suggest psychophysiological benefits for Tai-chi on chronic schizophrenia patients in terms of motor coordination and memory. Though both Tai-chi and exercise groups tended to manifest fewer symptoms than the control group, the exercise group showed better symptoms management than the Tai-chi group.

    Tai chi, also called taiji or tai chi chuan, is a form of mind-body exercise that originated from China. It combines Chinese martial arts and meditative movements that promote balance and healing of the mind and body, involving a series of slowly performed, dance-like postures that flow into one another. As it comprises mental concentration, physical balance, muscle relaxation, and relaxed breathing, tai chi shows great potential for becoming widely integrated into the prevention and rehabilitation of a number of medical and psychological conditions. A growing body of clinical research has begun to evaluate the efficacy of tai chi as a therapy for a variety of health issues. A systematic review and meta-analysis were carried out on randomized controlled trials (RCTs) and quasi-experimental (Q-E) trials that studied the effects of tai chi on psychological well-being. Drawn from English and Chinese databases, 37 RCTs and 5 Q-E studies published up to May 31, 2013 were included in the systematic review. The methodological quality of the RCTs was evaluated based on the following criteria: adequate sequence generation, allocation concealment, blinding, completeness of outcome data, selective reporting, and other potential biases. Statistical analyses were performed using Review Manager version 5.0. The studies in this review demonstrated that tai chi interventions have beneficial effects for various populations on a range of psychological well-being measures, including depression, anxiety, general stress management, and exercise self-efficacy. Meta-analysis was performed on three RCTs that used depression as an outcome measure (ES=-5.97; 95% CI -7.06 to -4.87), with I2=0%. In spite of the positive outcomes, the studies to date generally had significant methodological limitations. More RCTs with rigorous research design are needed to establish the efficacy of tai chi in improving psychological well-being and its potential to be used in interventions for populations with

    Patients suffering from Multiple Sclerosis (MS) experience a wide array of symptoms, including balance problems, mobility impairment, fatigue and depression. Physical exercise has recently been acknowledged as a treatment option complementary to medication. However, information regarding putative effects of structured exercise programs on neurological symptoms is sparse. Tai Chi, a Chinese martial art incorporating physical exercise and mindfulness training, has been shown to yield health benefits in various neurological groups. It seems particularly suitable for patients with motoric deficits as it challenges coordination and balance. The purpose of the current study was to explore the therapeutic value of structured Tai Chi training for coordination, balance, fatigue and depression in mildly disabled MS patients. A sample of 32 MS patients (Expanded Disability Status Scale, EDSS < 5) was examined. A structured Tai Chi course was devised and a Tai Chi group participated in two weekly sessions of 90 minutes duration for six months, while a comparison group received treatment as usual (TAU). Both groups were examined prior to and following the six-months interval with regards to balance and coordination performance as well as measures of fatigue, depression and life satisfaction. Following the intervention, the Tai Chi group showed significant, consistent improvements in balance, coordination, and depression, relative to the TAU group (range of effect-sizes: partial η2 = 0.16 - 0.20). Additionally, life satisfaction improved (partial η2 = 0.31). Fatigue deteriorated in the comparison group, whereas it remained relatively stable in the Tai Chi group (partial η2 = 0.24). The consistent pattern of results confirms that Tai Chi holds therapeutic potential for MS patients. Further research is needed to determine underlying working mechanisms, and to verify the results in a larger sample and different MS subgroups.

    [Purpose] This study was to examine the effects of 12 weeks of Tai Chi (TC) exercise on antioxidant capacity, and DNA damage/repair in young females who did not perform regular physical exercise. [Subjects and Methods] Ten female students from a Chinese university voluntarily participated in this program. All of them practiced the 24-form simplified Tai Chi, 5 times weekly, for 12 weeks. Plasma levels of superoxide dismutase (SOD), glutathione peroxidase (GPx), malondialdehyde (MDA), glutathione (GSH), hydroxyl radical inhibiting capacity (OH·-IC), 8-hydroxy-2'-deoxyguanosine (8-OHdG), and 8-oxoguanine DNA glycosylase (OGG1) were measured at 0, 8, and 12 weeks. Heart rate (HR) was monitored during the last set of the training session at 4, 8, and 12 weeks. [Results] Plasma SOD and OH·-IC levels were increased at 8 and 12 weeks compared to the baseline (0 weeks). Gpx and GSH levels did not change significantly throughout the study period. The plasma MDA level was decreased significantly at 8 weeks but not at 12 weeks compared to the baseline value. While the plasma 8-OHdG level did not change throughout the study period, the plasma OGG1 level was significantly increased at 8 and 12 weeks compared to the baseline value. [Conclusion] TC practice for 12 weeks efficiently improved the oxidative stress response in young females who did not perform regular physical exercise. The TC exercise also increased the DNA repairing capacity.

    At least 40% of patients with Parkinson's disease (PD) use one or more forms of alternative therapy (AT) to complement standard treatments. This article reviews the commonest forms of AT for PD, including acupuncture, tai chi, yoga, mindfulness, massage, herbal medicine, and cannabis. We discuss the current evidence for the clinical efficacy of each AT and discuss potential mechanisms, including those suggested by animal and human studies. With a few notable exceptions, none of the treatments examined were investigated rigorously enough to draw definitive conclusions about efficacy or mechanism. Tai chi, acupuncture, Mucuna pruriens, cannabinoids, and music therapy have all been proposed to work through specific mechanisms, although current evidence is insufficient to support or refute these claims, with the possible exception of Mucuna pruriens (which contains levodopa). It is likely that most ATs predominantly treat PD patients through general mechanisms, including placebo effects, stress reduction, and improved mood and sleep, and AT may provide patients with a greater locus of control regarding their illness.

    Bayesian inference provides a formal framework for updating knowledge by combining prior knowledge with current data. Over the past 10 years, the Bayesian paradigm has become a popular analytic tool in health research. Although the nursing literature contains examples of Bayes' theorem applications to clinical decision making, it lacks an adequate introduction to Bayesian data analysis. Bayesian data analysis is introduced through a fully Bayesian model for determining the efficacy of tai chi as an illustrative example. The mechanics of using Bayesian models to combine prior knowledge, or data from previous studies, with observed data from a current study are discussed. The primary outcome in the illustrative example was physical function. Three prior probability distributions (priors) were generated for physical function using data from a similar study found in the literature. Each prior was combined with the likelihood from observed data in the current study to obtain a posterior probability distribution. In each case, the posterior distribution showed that the probability that the control group is better than the tai chi treatment group was low. Bayesian analysis is a valid technique that allows the researcher to manage varying amounts of data appropriately. As advancements in computer software continue, Bayesian techniques will become more accessible. Researchers must educate themselves on applications for Bayesian inference, as well as its methods and implications for future research.

    The purpose of this study was to determine the effect of Tai Chi Chuan on the strategies of obstacle-crossing behavior in older adults aged over 65 years. Fifteen Tai Chi group (TCG) participants were compared with 15 general group (GG) participants. Kinematic parameters (by Vicon motion analysis system) and ground reaction forces (by Kistler force plates) were synchronously recorded. A two-way mixed-design ANOVA (α = 0.05) was used to test the effects of the group and the obstacle height. The TCG performed significantly faster stride velocities, longer stride lengths, and shorter stride times than GG while crossing the obstacles. TCG could also produce significantly larger forward ground reaction forces to propel the body and were able to make a significantly greater flexion angle of the hip of the leading leg compared with the GG. It was concluded that the TCG adopted a different strategy with GG to cross the obstacles and completed the crossing behavior more effectively.

    Falls in older adults, which often result from decreased balance and mobility, are an important public health issue. The American College of Sports Medicine recommends multidimensional balance and mobility training to prevent falls. In the past 20 years, Tai Chi Chu'an (tai chi) has been found to be effective in improving balance, reducing falls and fear of falling for older adults. Efficient use of time devoted to exercise is critical; therefore, more research is needed into the underlying mechanisms of balance and mobility improvements in older adults as a result of tai chi practice, so that these interventions can be most targeted and efficient. The purpose of this integrative review is twofold. First, evidence is presented to show that balance and mobility have been improved by tai chi in older adults. Second, potential mechanisms of balance improvement from research conducted in longtime tai chi practitioners, and from clinical research conducted in older adults, are offered. A PubMed search with the terms "tai chi" and "balance" entered simultaneously was conducted. Articles were included if they were systematic reviews, pilot or clinical trials, related to both balance and tai chi, and/or specifically related to determining the mechanisms potentially underlying tai chi's effects. The systematic reviews and meta-analyses show that aspects of tai chi research findings remain equivocal. In spite of the inconclusiveness of these review findings, many researchers have considered tai chi worthy of further investigation. Furthermore, practitioners in the clinic and those who deliver exercise in the community have evidently embraced tai chi as an appropriate exercise for older adults. This review, spanning 2 decades, suggests that tai chi has impacted the health and health behaviors of many older adults. Going forward, informing novel balance and mobility rehabilitation by uncovering mechanisms of tai chi's effects definitively may be the most important area of

    Chronic obstructive pulmonary disease (COPD) is a chronic, progressively debilitating condition that is prevalent in the US and worldwide. Patients suffer from progressive dyspnea and exercise intolerance. Physical exercise is beneficial, but conventional pulmonary rehabilitation programs are underutilized. There remains a need for novel interventions that improve symptoms, quality-of-life, and functional capacity. Tai chi is an increasingly popular mind-body exercise that includes physical exercise, breathing training, mindful awareness, and stress management--components that are essential to the self-management of COPD. There are, however, limited data on the effectiveness of tai chi as a therapeutic intervention in this population. The Primary Aims are to evaluate the efficacy, safety, and feasibility of a 12-week tai chi program for patients with COPD. We utilize a randomized controlled trial design, with participants assigned in a 2:1 ratio to either a group tai chi program (N = 63) or a time/attention-matched education control (N = 31). Our primary outcomes are COPD-specific quality-of-life and exercise capacity. Secondary outcomes include dyspnea, mood, functional status, self-efficacy, and lung function. Cardiopulmonary exercise testing is done in a subset of patients (N = 50). To explore optimal training duration, a subgroup of patients in tai chi are randomly assigned to complete an additional 12 weeks training (total 24 weeks) (Exploratory Aim 1). To explore the impact of a simplified seated intervention including only a subset of tai chi's training components, a third randomly assigned group (N = 31) receives a 12- week mind-body breathing program (N = 31) (Exploratory Aim 2). Results of the BEAM study (Breathing, Education, Awareness, Movement) will provide preliminary evidence regarding the value of tai chi for improving quality of life and exercise capacity in patients with COPD, including information regarding optimal duration. They will also inform

    2001-01-01

    This paper develops a physical model describing the Yin-Yang balance in the tai-chi diagrain via the melting and freezing processes taking place in a rotating device. First, a physical model is established for a melting and freezing rotating device applied for transferring heat from a heat source to a heat sink. The device consists of two concentric cylinders with a phase change material being filled between them. During the melting process, heat is supplied from the heat source to the device, and the phase change material in the device melts. The melting process is equivalent to yang in the tai-chi diagram. During the freezing process, heat is discharged from the device to the heat sink, and the phase change material in the device freezes. The freezing process is equivalent to yin in the tai-chi diagram. The moving phase boundaries of the melting and freezing processes form two curves,representing the interface curves between the yin and yang in the tai-chi diagram. The variation of the thermal strength in the heat source and heat sink represents the variation of the yin -yang balance in the tai-chi diagram.

    Tai Chi has frequently been used as a preventive measure against falling in at-risk populations. However, studies have yielded contradictory results, and literature reviews have considered only a small number of trials and have not addressed some key aspects, such as sources of heterogeneity and publication bias. This study includes 13 controlled trials published before June 2015 that analyzed the effectiveness of Tai Chi in fall prevention in populations of frail and at-risk adults. The effect measure used in this meta-analysis was absolute risk reduction (ARR) with a 95% confidence interval (CI). According to our findings, practice of Tai Chi significantly prevents the risk of falling (ARR, [Formula: see text]; 95% CI: [Formula: see text], [Formula: see text]). The heterogeneity of results across the trials was low, with a reduced risk of publication bias, and no significant effect differences were observed between studies comparing Tai Chi with other interventions or non-treatment. We therefore conclude that Tai Chi is more effective than other measures, or no intervention, for fall prevention in at-risk populations. Further research is warranted to analyze the consequences of falls and to study the episodes rather than the cases of falls.

    Cognitive impairment is one of the most common problem saffecting older adults. In this study, we investigated whether Tai Chi Chuan and Baduanjin practice can modulate mental control functionand the resting state functional connectivity (rsFC) of the cognitive control network in older adults. Participants in the two exercise groups practiced either Tai Chi Chuan or Baduanjin for 12 weeks, and those in the control group received basic health education. Memory tests and fMRI scans were conducted at baseline and at the end of the study. Seed-based (bilateral dorsolateral prefrontal cortex, DLPFC) rsFC analysis was performed. We found that compared to the controls, 1) both Tai Chi Chuan and Baduanjin groups demonstrated significant improvements in mental control function; 2) the Tai Chi Chuan group showed a significant decrease in rsFC between the DLPFC and the left superior frontal gyrus (SFG) and anterior cingulate cortex; and 3) the Baduanjin group showed a significant decrease in rsFC between the DLPFC and the left putamen and insula. Mental control improvement was negatively associated with rsFC DLPFC-putamen changes across all subjects. These findings demonstrate the potential of Tai Chi Chuan and Baduanjin exercises in preventing cognitive decline. PMID:28169310

    Patients with schizophrenia are characterized by high prevalence rates and chronicity that often leads to long-term institutionalization. Under the traditional medical model, treatment usually emphasizes the management of psychotic symptoms through medication, even though anti-psychotic drugs are associated with severe side effects, which can diminish patients' physical and psychological well-being. Tai-chi, a mind-body exercise rooted in Eastern health philosophy, emphasizes the motor coordination and relaxation. With these potential benefits, a randomized controlled trial (RCT) is planned to investigate the effects of Tai-chi intervention on the cognitive and motor deficits characteristic of patients with schizophrenia. A 3-arm RCT with waitlist control design will be used in this study. One hundred and fifty three participants will be randomized into (i) Tai-chi, (ii) exercise or (iii) waitlist control groups. Participants in both the Tai-chi and exercise groups will receive 12-weeks of specific intervention, in addition to the standard medication and care received by the waitlist control group. The exercise group will serve as a comparison, to delineate any unique benefits of Tai-chi that are independent of moderate aerobic exercise. All three groups will undergo three assessment phases: (i) at baseline, (ii) at 12 weeks (post-intervention), and (iii) at 24 weeks (maintenance). All participants will be assessed in terms of symptom management, motor coordination, memory, daily living function, and stress levels based on self-perceived responses and a physiological marker. Based on a promising pilot study conducted prior to this RCT, subjects in the Tai-chi intervention group are expected to be protected against deterioration of motor coordination and interpersonal functioning. They are also expected to have better symptoms management and lower stress level than the other treatment groups. The trail has been registered in the Clinical Trials Center of the

    To examine the effects of a 10-week Tai Chi (TC) program on neuropsychological, psychological, and physical health of female cancer survivors. Twenty-three women with a history of cancer participated in 60-min TC classes two times/week for 10-weeks. Before and after the intervention, participants completed neuropsychological tests (memory, executive functioning, language, and attention); 5 tests of balance; and self-report questionnaires of neuropsychological complaints, stress and mood, and fatigue. After the 10-week session, participants evidenced fewer neuropsychological complaints and enhanced neuropsychological functioning. They also demonstrated improved balance and reported better psychological functioning. Results suggest that TC may promote gains in neuropsychological functioning, in addition to previously demonstrated improvements in physical and psychological health. These findings support the need for controlled trials examining the potential benefits of TC on neuropsychological functioning after cancer. Copyright © 2011 Elsevier Ltd. All rights reserved.

    This study examined the effects of regular Tai Chi (TC) exercise on the kinaesthesia of the knee and ankle joints of older women. A total of 43 women aged 55-68 years participated in this study. In a 24-week study period, the TC group (n = 22) underwent an organized TC exercise, whereas the control group (n = 21) maintained a sedentary lifestyle. Customized instruments were used to measure the threshold for the detection of the passive motion of the knee and ankle joints. After 24 weeks, the TC group showed a significantly smaller threshold for the detection of passive motion of knee extension (31.4%, p = 0.009), knee flexion (27.0%, p = 0.044), and ankle dorsal flexion (28.9%, p = 0.014) than the control group. Other comparisons showed no significant differences. The 24-week TC exercise benefited the lower-limb kinaesthesia of the knee joint flexion and extension and ankle dorsal flexion.

    The risk of accidental falls and fall-related injuries increases with age. Regular physical exercises can delay the age-related changes affecting postural balance and reduce the risk of falls. Although Tai Chi (TC) has become a popular exercise among the elderly, does regular TC exercise lead to fewer falls and fall-related injuries? Who would receive the most benefit from TC exercise? What style of TC is best for fall risk reductions? What is the minimum amount of TC exercise needed before its positive effect is observed? How does the effect of TC exercise compare to other physical exercises? The goal of this study is to conduct a systematic review of recent literature on TC's effectiveness for reducing fall risks in elders. A summary and analysis is provided for the following variables: targeted subject population, TC curriculum, comparative effect, and outcome measures.

    Arthralgia is common and debilitating for a significant proportion of breast cancer survivors (BCSs) and leads to poor adherence to aromatase inhibitors (AIs). Despite increased recognition of the negative impact of arthralgia on function and the poor adherence that results, very few interventions have been developed to target this side effect. This study aimed to determine the feasibility of tai chi to improve well-being for women experiencing AI-associated arthralgias (AIAAs). The study was a pilot to (1) demonstrate the feasibility of recruitment and retention for a tai chi trial, (2) determine the safety of tai chi, and (3) identify the outcomes (function, pain, and quality of life[QOL]) that tai chi may impact. The study took place at the Gilda's Club South Jersey in Linwood, NJ, USA. Postmenopausal women with a history of stage I-III breast cancer reporting AIAA were enrolled. Group tai chi was practiced for 1 h 2 ×/wk for 8 wks. Functional outcomes included (1) sit-and-reach (SR), (2) functional reach (FR), (3) the Berg Balance Scale (BBS), and (4) timed up-and-go (TUG). The following patient-reported outcomes (PROs) were evaluated pre- and postintervention: (1) the Hospital Anxiety and Depression Scale (HADS), (2) the Functional Assessment of Cancer Therapy-Breast (FACT-B), (3) the Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-Fatigue), (4) the Brief Pain Inventory (BPI), (5) the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT-GOG-Ntx), and (6) the Functional Assessment of Chronic Illness Therapy- Spiritual Well-being Scale (FACIT-Sp). Participants also recorded their tai chi experiences in a journal. For the 12 participants, adherence to the classes was 75%, with no adverse events reported. Participants experienced significant improvement from baseline to follow-up for the HADS anxiety (P = .003) and depression (P = .020) scales, the emotional well-being scale of the FACT-B (P = .027), the FACIT

    Stress is common in junior secondary school students (JSSS). This study aimed to determine the feasibility and effectiveness of a Chen-style Tai Chi programme for stress reduction in JSSS. A non-equivalent pre-test/post-test control group design was adopted, and a convenience sample of 69 JSSS was recruited. The experimental group (n = 32) joined a Chen-style Tai Chi programme, which included 10 sessions of 80-minute Tai Chi training (one session per week). The control group (n = 37) proceeded with self-study. Participants' stress levels were assessed using the Perceived Stress Scale. Feasibility was determined as the percentage of participants completing and attending the programme. Effectiveness was measured as the significant difference in changes in stress levels before and after the intervention between the two groups. Results preliminarily supported that the programme was feasible for JSSS. Completion rate was 100%, and attendance rate was 90%. However, no significant difference was noted in changes in stress levels before and after the intervention between the two groups. The potential health benefits of Tai Chi could not be detected owing to the restrictions imposed by the research setting and study limitations. The present study represents initial efforts in this direction and serves as reference for future study. Copyright © 2012 John Wiley & Sons, Ltd.

    Full Text Available Recently, several studies assessed the effectiveness of Tai Chi for Parkinson's disease (PD, but the role of Tai Chi in the management of PD remained controversial. Therefore, the purpose of this systematic review is to evaluate the evidence on the efficacy of Tai Chi for PD.Six English and Chinese electronic databases, up to April 2014, were searched to identify relevant studies. The risk of bias in eligible studies was assessed by Cochrane Collaboration's tools. The primary outcomes were motor function, balance and gait in individuals with PD. Standardized mean difference (SMD and 95% confidence intervals (CI of random-effect model were calculated. And heterogeneity was assessed based on the I2 statistic.7 randomized controlled trials and 1 non-randomized controlled trial were eligible. The aggregated results suggested that Tai Chi showed beneficial effects in improving motor function (SMD, -0.57; 95% CI -1.11 to -0.04; p = 0.03, balance (SMD, 1.22; 95% CI 0.80 to 1.65; p<0.00001 and functional mobility (SMD, 1.06; 95% CI 0.68 to 1.44; p<0.00001 in patients with PD, but not in improving gait velocity (SMD, -0.02; 95% CI -0.58 to 0.54; p = 0.94, step length (SMD, -0.00; 95% CI -0.57 to 0.56; p = 0.99, or gait endurance (SMD, 0.53; 95% CI -0.07 to 1.12; p = 0.08. Comparing with other active therapies, however, Tai Chi only showed better effects in improving balance (SMD, 0.74; 95% CI 0.38 to 1.10; p<0.0001.Tai Chi should be a valid complementary and alternative therapy for PD, especially in improving motor function and balance. However, more studies with long follow-up are warrant to confirm the current finding of Tai Chi for PD.

    Abstract Falls amongst older people is a global public health concern. Whilst falling is not a typical feature of ageing, older people are more likely to fall. Fall injuries amongst older people are a leading cause of death and disability. Many older people do not do regular exercise so that they lose muscle tone, strength, and flexibility which affect balance and predispose them to falls. The management of falls in residential care settings is a major concern with strategies for prevention and monitoring a focus in this setting. Yoga and tai chi have shown potential to improve balance and prevent falls in older adults. They also have potential to improve pain and quality of life. The aim of this study was to determine the feasibility of conducting a 3-arm RCT with frail older people in a residential care setting to test the hypothesis that a 14 week modified tai chi or yoga program is more effective than usual care activity in improving balance function, quality of life, pain experience and in reducing number of falls. There were no statistically significant differences between the three groups in the occurrence of falls. Yoga demonstrated a slight decrease in fall incidence; quality of life improved for the tai chi group. Only the yoga group experienced a reduction in average pain scores though not statistically significant. The findings of the study suggest it is possible to safely implement modified yoga and tai chi in a residential care setting and evaluate this using RCT design. They show positive changes to balance, pain and quality of life and a high level of interest through attendance amongst the older participants. The results support offering tai chi and yoga to older people who are frail and dependent with physical and cognitive limitations.

    Full Text Available Abstract Background Vestibular rehabilitation (VR is a well-accepted exercise program intended to remedy balance impairment caused by damage to the peripheral vestibular system. Alternative therapies, such as Tai Chi (TC, have recently gained popularity as a treatment for balance impairment. Although VR and TC can benefit people with vestibulopathy, the degree to which gait improvements may be related to neuromuscular adaptations of the lower extremities for the two different therapies are unknown. Methods We examined the relationship between lower extremity neuromuscular function and trunk control in 36 older adults with vestibulopathy, randomized to 10 weeks of either VR or TC exercise. Time-distance measures (gait speed, step length, stance duration and step width, lower extremity sagittal plane mechanical energy expenditures (MEE, and trunk sagittal and frontal plane kinematics (peak and range of linear and angular velocity, were measured. Results Although gait time-distance measures were improved in both groups following treatment, no significant between-groups differences were observed for the MEE and trunk kinematic measures. Significant within groups changes, however, were observed. The TC group significantly increased ankle MEE contribution and decreased hip MEE contribution to total leg MEE, while no significant changes were found within the VR group. The TC group exhibited a positive relationship between change in leg MEE and change in trunk velocity peak and range, while the VR group exhibited a negative relationship. Conclusion Gait function improved in both groups consistent with expectations of the interventions. Differences in each group's response to therapy appear to suggest that improved gait function may be due to different neuromuscular adaptations resulting from the different interventions. The TC group's improvements were associated with reorganized lower extremity neuromuscular patterns, which appear to promote a faster

    The risk of oxidative stress-related metabolic diseases increases with menopause and physical inactivity. We hypothesized that an 8-week Tai Chi (TC) training program (2 sessions in class; 2 sessions at home; 1-1:15/session) would improve antioxidant capacity and reduce cardiovascular risks in both pre- (n = 8) and postmenopausal (n = 7) sedentary women. Selected measures of physical fitness and blood parameters were analyzed before and after the program. Besides the well-known effects of TC on balance, flexibility, and maximum leg extensor strength, TC (1) increased erythrocyte glutathione peroxidase activity-an aerobic training-responsive antioxidant enzyme-and plasma total antioxidant status and (2) decreased plasma total homocysteine, a cardiovascular risk marker. In addition to being a low-velocity, low-impact, and relatively safe, TC is a suitable physical activity design for pre- and postmenopausal women to increase antioxidant defenses. Investigating breathing effects during TC movements would be an interesting area for further research in diseases prevention.

    Tai chi chuan (TCC) has been used as a mind-body practice in Asian culture for centuries to improve wellness and reduce stress and has recently received attention by researchers as an exercise intervention. A review of the English literature on research in TCC published from 1989 to 2006 identified 20 prospective, randomized, controlled clinical trials in a number of populations, including elderly participants (7 studies), patients with cardiovascular complications (3 studies), patients with chronic disease (6 studies), and patients who might gain psychological benefit from TCC practice (2 studies). However, only the studies of TCC in the elderly and 2 studies of TCC for cardiovascular disease had adequate designs and size to allow conclusions about the efficacy of TCC. Most (11 studies) were small and provided limited information on the benefit of TCC in the settings tested. There is growing awareness that cancer survivors represent a population with multiple needs related to physical deconditioning, cardiovascular disease risk, and psychological stress. TCC as an intervention may provide benefit to cancer survivors in these multiple areas of need based on its characteristics of combining aspects of meditation and aerobic exercise. However, little research has been conducted to date to determine the benefit of TCC in this population. We propose a model to study the unique characteristics of TCC compared to physical exercise that may highlight characteristic features of this mind-body intervention in cancer survivors.

    Although numerous studies have linked t'ai chi chuan (TCC) practice with benefits for balance, reduction in the number of falls, and in the fear of falling, most of them did not address the causes of these benefits in depth. Some studies, however, sought to determine the causes from the biomechanical point of view. This article aims to thoroughly describe and critically review recent papers on foot-ground contact in TCC practice, one of the parameters involved in balance biomechanics in TCC performance. No previous review on this subject has been found. Nine electronic databases were searched for publications between 1996 and 2013. Studies were excluded if they were not published in English or were abstracts, posters, or summaries from conferences. From a total of 195 articles identified, 4 randomized controlled trials and 3 non-randomized controlled trials were eligible for the analysis. The number of studies that assessed foot-ground contact in TCC and effects on normal gait, postural control improvement, and fall prevention is still quite small. These studies were based on intervention protocols and used populations that were too heterogeneous to allow reliable comparisons. According to the studies analyzed, TCC practice clearly improved parameters associated with foot-ground contact. Nevertheless, the manner in which these benefits are transferred to daily displacement habits still remains unclear.

    [Purpose] To explore the changes in heart-rate variability (HRV) of survivors of nasopharyngeal cancer (NPC) before, during, and after a Tai Chi (TC) Qigong exercise. [Subjects and Methods] Eleven survivors of NPC participated voluntarily in the study. The heart rate of each participant was measured continuously for 1 minute before the TC Qigong intervention, during the 5-minute TC Qigong intervention, and for 1 minute after the intervention, using a Polar heart-rate monitor. Spectral HRV was expressed in terms of normalised low frequency (LF) power, normalised high frequency (HF) power, and the low frequency/high frequency (LF/HF) power ratio. [Results] Both the LF-power and the HF-power components had significant time effects. However, the time effect of the LF/HF power ratio was not significant. Post hoc contrast analysis revealed a significant decrease in LF power and a concomitant increase in HF power during the 4th minute and 5th minute of the TC Qigong exercise. [Conclusion] Five minutes of TC Qigong exercise was found to improve HRV by increasing HF power and decreasing LF power, but these effects were transient. TC Qigong might be an appropriate exercise for improving the ANS function and psychological and cardiac health of survivors of NPC.

    Tai Chi Chuan (TCC) practice is currently intentionally applied in clinical populations, especially those with cardiovascular diseases because of its potential benefits on the autonomic nervous system. The long-term effect of TCC practice on heart rate variability (HRV) remains largely unknown. In this study, we recruited 23 TCC practitioners whose experience averaged approximately 21 years and 19 controls matched by age, sex and education to examine the effect of TCC practice on the autonomic nervous system during a resting state and during an abdominal breathing state. HRV was measured by traditional electrocardiogram (ECG) recording. The results showed that the low frequency, total power frequency, and normalized low frequency components and the low-frequency/high-frequency ratio were significantly higher, whereas the normalized high frequency was significantly lower in the TCC practitioners relative to controls during the abdominal breathing state. However, we did not detect any significant difference in the HRV measures during the resting state between the two groups. Additionally, TCC experience did not correlate with HRV components either in the abdominal state or the resting state in the TCC group. Considering all of these findings, we suggest that TCC improves vagal activity and the balance between sympathetic and parasympathetic activity during the relaxation state. This study also provides direct physiological evidence for the role of TCC practice in relaxation.

    Full Text Available Both the incidence and severity of herpes zoster (HZ or shingles increase markedly with increasing age in association with a decline in varicella zoster virus (VZV-specific immunity. Considerable evidence shows that behavioral stressors, prevalent in older adults, correlate with impairments of cellular immunity. Moreover, the presence of depressive symptoms in older adults is associated with declines in VZV-responder cell frequency (VZV-RCF, an immunological marker of shingles risk. In this review, we discuss recent findings that administration of a relaxation response-based intervention, tai chi chih (TCC, results in improvements in health functioning and immunity to VZV in older adults as compared with a control group. TCC is a slow moving meditation consisting of 20 separate standardized movements which can be readily used in elderly and medically compromised individuals. TCC offers standardized training and practice schedules, lending an important advantage over prior relaxation response-based therapies. Focus on older adults at increased risk for HZ and assay of VZV-specific immunity have implications for understanding the impact of behavioral factors and a behavioral intervention on a clinically relevant end-point and on the response of the immune system to infectious pathogens.

    Full Text Available Whether Tai Chi Chuan (TCC can influence the intrinsic functional architecture of the human brain remains unclear. To examine TCC-associated changes in functional connectomes, resting-state functional magnetic resonance images were acquired from 40 older individuals including 22 experienced TCC practitioners (experts and 18 demographically matched TCC-naïve healthy controls, and their local functional homogeneities across the cortical mantle were compared. Compared to the controls, the TCC experts had significantly greater and more experience-dependent functional homogeneity in the right postcentral gyrus (PosCG and less functional homogeneity in the left anterior cingulate cortex (ACC and the right dorsal lateral prefrontal cortex (DLPFC. Increased functional homogeneity in the PosCG was correlated with TCC experience. Intriguingly, decreases in functional homogeneity (improved functional specialization in the left ACC and increases in functional homogeneity (improved functional integration in the right PosCG both predicted performance gains on attention network behavior tests. These findings provide evidence for the functional plasticity of the brain’s intrinsic architecture toward optimizing locally functional organization, with great implications for understanding the effects of TCC on cognition, behavior and health in aging population.

    Full Text Available In Parkinson's disease (PD, wearing off and side effects of long-term medication and complications pose challenges for neurologists. Although Tai Chi is beneficial for many illnesses, its efficacy for PD remains uncertain. The purpose of this review was to evaluate the efficacy and safety of Tai Chi for PD.Randomized controlled trials (RCTs of Tai Chi for PD were electronically searched by the end of December 2013 and identified by two independent reviewers. The tool from the Cochrane Handbook 5.1 was used to assess the risk of bias. A standard meta-analysis was performed using RevMan 5.2 software.Ten trials with PD of mild-to-moderate severity were included in the review, and nine trials (n = 409 were included in the meta-analysis. The risk of bias was generally high in the blinding of participants and personnel. Improvements in the Unified Parkinson's Disease Rating Scale Part III (mean difference (MD -4.34, 95% confidence interval (CI -6.67--2.01, Berg Balance Scale (MD: 4.25, 95% CI: 2.83-5.66, functional reach test (MD: 3.89, 95% CI: 1.73-6.04, Timed Up and Go test (MD: -0.75, 95% CI: -1.30--0.21, stride length (standardized MD: 0.56, 95% CI: 0.03-1.09, health-related quality of life (standardized MD: -1.10, 95% CI: -1.81--0.39 and reduction of falls were greater after interventions with Tai Chi plus medication. Satisfaction and safety were high. Intervention with Tai Chi alone was more effective for only a few balance and mobility outcomes.Tai Chi performed with medication resulted in promising gains in mobility and balance, and it was safe and popular among PD patients at an early stage of the disease. This provides a new evidence for PD management. More RCTs with larger sample size that carefully address blinding and prudently select outcomes are needed.

    Osteoporosis is a major health problem in postmenopausal women. Evidence suggests the importance of oxidative stress in bone metabolism and bone loss. Tea consumption may be beneficial to osteoporosis due to its antioxidant capability. However, lack of objective data characterizing tea consumption has hindered the precise evaluation of the association between tea ingestion and bone mineral density in previous questionnaire-based epidemiological studies. On the other hand, although published studies suggest that Tai Chi (TC) exercise can benefit bone health and may reduce oxidative stress, all studies were conducted using a relatively healthy older population, instead of a high-risk one such as osteopenic postmenopausal women. Therefore, this study was designed to test an intervention including green tea polyphenol (GTP) and TC exercise for feasibility, and to quantitatively assess their individual and interactive effects on postmenopausal women with osteopenia. One hundred and forty postmenopausal women with osteopenia (defined as bone mineral density T-score at the spine and/or hip between 1 to 2.5 SD below the reference database) were randomly assigned to 4 treatment arms: (1) placebo group receiving 500 mg medicinal starch daily, (2) GTP group receiving 500 mg of GTP per day, (3) placebo+TC group receiving both placebo treatment and TC training (60-minute group exercise, 3 times per week), and (4) GTP+TC group receiving both GTP and TC training for 24 weeks. The outcome measures were bone formation biomarker (serum bone alkaline phosphatase), bone resorption biomarker (serum tartrate resistant acid phosphatase), and oxidative DNA damage biomarker (urinary 8-hydroxy-2'-deoxyguanosine). All outcome measures were determined at baseline, 4, 12, and 24 weeks. Urinary and serum GTP concentrations were also determined at baseline, 4, 12, and 24 weeks for bioavailability.

    Full Text Available BACKGROUND: Currently, several studies assessed the role of Tai Chi (TC in management of chronic obstructive pulmonary disease, but these studies have wide variation of sample and convey inconclusive results. We therefore undertook a meta-analysis to assess the effects of TC. METHODS: A computerized search through electronic databases was performed to obtain sample studies. The primary outcomes were 6-min walking distance (6MWD and dyspnea. Secondary outcomes included health-related quality of life and pre-bronchodilator spirometry. Weighted mean differences (WMDs and 95% confidence intervals (CIs were calculated and heterogeneity was assessed with the I(2 test. A random-effects meta-analysis model was applied. RESULTS: Eight randomized controlled trials involving 544 patients met the inclusion criteria. The pooled WMDs were 34.22 m (95% CI 21.25-47.20, P<0.00001 for 6 MWD, -0.86 units (95% CI -1.44--0.28, P = 0.004 for dyspnea, 70 ml (95% CI 0.02-0.13, P = 0.01 for FEV1, 120 ml (95% CI 0.00-0.23, P = 0.04 for FVC. TC significantly improved the Chronic Respiratory Disease Questionnaire total score, and the St George's Respiratory Questionnaire score except impact score. CONCLUSIONS: Findings suggest that TC may provide an effective alternative means to achieve results similar to those reported following participation in pulmonary rehabilitation programs. Further studies are needed to substantiate the preliminary findings and investigate the long-term effects of TC.

    Full Text Available Background. Tai Chi is a traditional Chinese medicine exercise used for improving neuromuscular function. This study aimed to investigate the effects of Tai Chi versus proprioception exercise program on neuromuscular function of the ankle in elderly people. Methods. Sixty elderly subjects were randomly allocated into three groups of 20 subjects per group. For 16 consecutive weeks, subjects participated in Tai Chi, proprioception exercise, or no structured exercise. Primary outcome measures included joint position sense and muscle strength of ankle. Subjects completed a satisfaction questionnaire upon study completion in Tai Chi and proprioception groups. Results. (1 Both Tai Chi group and proprioception exercise group were significantly better than control group in joint position sense of ankle, and there were no significant differences in joint position sense of ankle between TC group and PE group. (2 There were no significant differences in muscle strength of ankle among groups. (3 Subjects expressed more satisfaction with Tai Chi than with proprioception exercise program. Conclusions. None of the outcome measures on neuromuscular function at the ankle showed significant change posttraining in the two structured exercise groups. However, the subjects expressed more interest in and satisfaction with Tai Chi than proprioception exercise.

    Full Text Available The aims of this article were to (a investigate whether practicing Tai Chi has an effect on stress, self-esteem, and perceived life expectancy and (b contrast a structural model of relation between the three latter variables taking into account age. One scale to assess stress, another scale to assess perceived life expectancy, and the 10-item Rosenberg’s Self-Esteem Scale were administrated to a nonprobability sample of 86 Tai Chi practitioners and 91 sedentary persons. Tai Chi practitioners had a lower level of stress, a greater self-esteem, and a greater perceived life expectancy than sedentary persons. Self-esteem had an effect on stress and perceived life expectancy, and stress had an effect on perceived life expectancy in both Tai Chi practitioners and sedentary persons. Age was correlated to self-esteem among sedentary persons, but not among Tai Chi practitioners. Age had a direct effect on perceived life expectancy among Tai Chi practitioners, but not among sedentary persons. It is concluded that Tai Chi practice has a beneficial effect on stress, perceived life expectancy, and self-esteem.

    Objective To examine feasibility, qualitative feedback and satisfaction associated with a 4-session introduction to Tai Chi for veterans with post-traumatic stress symptoms. Design We observed and reported recruitment and retention rates, participant characteristics, adherence, and satisfaction across 2 cohorts. We also examined qualitative feedback provided by questionnaires, focus groups and individual interviews. Main outcome measures Rates of recruitment and retention, focus group and individual feedback interviews, self-reported satisfaction. Participants 17 veterans with post-traumatic stress symptoms. Results Almost 90% (17/19) of those eligible following the telephone screen enrolled in the programme. Three-quarters (76.4%) of the participants attended at least 3 of the 4 Tai Chi sessions. Qualitative data analysis revealed themes indicating favourable impressions of the Tai Chi sessions. In addition, participants reported feeling very engaged during the sessions, and found Tai Chi to be helpful for managing distressing symptoms (ie, intrusive thoughts, concentration difficulties, physiological arousal). Participants also reported high satisfaction: 93.8% endorsed being very or mostly satisfied with the programme. All participants (100%) indicated that they would like to participate in future Tai Chi programmes and would recommend it to a friend. Conclusions Tai Chi appears to be feasible and safe for veterans with symptoms of post-traumatic stress disorder (PTSD), is perceived to be beneficial and is associated with high rates of satisfaction. This study highlights the need for future investigation of Tai Chi as a novel intervention to address symptoms of PTSD. PMID:27899398

  6. Efficacy of Tai Chi on pain, stiffness and function in patients with osteoarthritis: a meta-analysis.

    Jun-Hong Yan

    Full Text Available BACKGROUND: Whether Tai Chi benefits patients with osteoarthritis remains controversial. We performed a meta-analysis to assess the effectiveness of Tai Chi exercise for pain, stiffness, and physical function in patients with osteoarthritis. METHODS: A computerized search of PubMed and Embase (up to Sept 2012 was performed to identify relevant studies. The outcome measures were pain, stiffness, and physical function. Two investigators identified eligible studies and extracted data independently. The quality of the included studies was assessed by the Jadad score. Standard mean differences (SMDs and 95% confidence intervals (CIs were calculated and pooled using a random effects model. The change in outcomes from baseline was compared to the minimum clinically important difference. RESULTS: A total of seven randomized controlled trials involving 348 patients with osteoarthritis met the inclusion criteria. The mean Jadad score was 3.6. The pooled SMD was -0.45 (95% CI -0.70--0.20, P = 0.0005 for pain, -0.31 (95% CI -0.60--0.02, P = 0.04 for stiffness, and -0.61 (95% CI -0.85--0.37, P<0.00001 for physical function. A change of 32.2-36.4% in the outcomes was greater than the minimum clinically important difference. CONCLUSIONS: Twelve-week Tai Chi is beneficial for improving arthritic symptoms and physical function in patients with osteoarthritis and should be included in rehabilitation programs. However, the evidence may be limited by potential biases; thus, larger scale randomized controlled trials are needed to confirm the current findings and investigate the long-term effects of Tai Chi.

    The biochemical mechanisms involving oxidative stress to explain the relationship between exercise and healthy aging are still unclear. Tai Chi participants and matched sedentary volunteers age 45 and above were enrolled. Glutathione peroxidase (GPx), superoxide dismutase (SOD), and catalase (CAT) activities; levels of DNA damage using the comet assay; and malondialdehyde (MDA) and advanced glycation end products (AGE) were determined at 0, 6, and 12 months. Tai Chi subjects had decreased normal and increased mildly damaged DNA with elevated GPx activity after 6 months (n=25). Plasma MDA and AGE concentrations decreased significantly after 12 months (n=15) accompanied by increased SOD activity. This may be attributed to the hormesis effect, whereby mild induction of oxidative stress at the first 6 months of exercise resulted in stimulation of antioxidant defenses. These parameters were unchanged in the sedentary subjects in the first 6 months (n=27) except for elevated SOD activity. After 12 months, the sedentary subjects (n=17) had decreased normal DNA and increased severely damaged DNA with unaltered MDA and AGE levels while SOD and GPx activities were significantly elevated. Regular Tai Chi exercise stimulated endogenous antioxidant enzymes and reduced oxidative damage markers.

    [Purpose] This study aimed to determine the correlation between center of pressure and functional balance in non-faller elderly practitioners of Tai Chi. [Subjects and Methods] For the study, nine non-faller elderly practitioners of Tai Chi who were able to maintain a standing posture and walk independently were recruited. Timed one-leg standing and timed up-and-go tests were used as functional balance tests and force platform to measure the center of pressure. The Pearson correlation coefficient was calculated for the timed up-and-go/timed one-leg standing test scores and center of pressure parameter values. [Results] None of the correlations was statistically significant, but moderate correlations were observed between the pairs timed one-leg standing/sway area of center of pressure, timed one-leg standing/standard deviation of center of pressure in the mediolateral direction, timed one-leg standing/mean velocity of center of pressure in the anteroposterior direction, and timed up-and-go test sway area of center of pressure. [Conclusion] Timed one-leg standing is more appropriate than timed up-and-go test for the measurement of functional balance in non-faller elderly practitioners of Tai Chi.

Patients and methods: “Hidden elderly” is a term used to describe older adults who are socially isolated and refuse social participation. This pilot randomized controlled trial recruited 48 older adults aged 60 or above who did not engage in any social activity. They were randomized into tai chi qigong (n=24 and standard care control (n=24 groups. The former group underwent a three-month program of two 60-minute sessions each week, with the socially active volunteers paired up with them during practice. Standard care included regular home visits by social workers. Primary outcomes were assessed by means of the Lubben social network and De Jong Gieveld loneliness scales, and by a revised social support questionnaire. Secondary outcomes were covered by a mental health inventory and the Rosenberg self-esteem scale, and quality of life by using the 12-Item Short Form Health Survey. Data was collected at baseline, and at three and six months thereafter. Results: The generalized estimating equations model revealed general improvement in outcomes among participants on the tai chi qigong program. In particular, participants reported a significantly greater improvement on the loneliness scale (B=-1.32, 95% confidence interval [CI] -2.54 to -0.11, P=0.033 and the satisfaction component of the social support questionnaire (B=3.43, 95% CI 0.10–6.76, P=0.044 than the control group. Conclusion: The pilot study confirmed that tai chi qigong with elderly neighborhood volunteers is a safe and feasible social intervention for hidden elderly. Its potential benefits in

    Full Text Available This study was designed to determine the relationship between physical activity and the task-switching aspect of executive function by investigating the modulating roles of age, modality of physical activity, and type of cognitive function using behavioral and event-related potential (ERP assessments. Sixty-four participants were assigned to one of four groups based on age and history of physical activity: older adults performing endurance exercise (OEE, older adults practicing Tai Chi Chuan (OTC, older adults with a sedentary lifestyle (OSL, and young adults (YA. Study participants completed a task-switching task under homogeneous and heterogeneous conditions while ERPs were recorded. The results revealed that YA had shortest reaction times compared with the three older adults groups, with OSL exhibiting the longest reaction time. YA also exhibited shorter P3 latency than OSL. No differences were observed in P3 amplitude between YA, OEE, and OTC; however, all three groups had a significantly larger P3 amplitude compared with OSL in both task conditions. In conclusion, age and participation in physical activity influence the relationship between physical activity and task-switching, and a positive relationship was observed regardless of the modality of physical activity and type of cognitive function. Our ERP findings support the model of the scaffolding theory of aging and cognition and suggest that regular participation in endurance exercise and Tai Chi Chuan may have equivalent beneficial effects on cognition at the behavioral and neuroelectric levels.

    Full Text Available Tai Chi (TC is a slow-motion contemplative exercise that is associated with improvements in sensorimotor measures, including decreased force variability, enhanced tactile acuity, and improved proprioception, especially in elderly populations. Here, we carried out two studies evaluating the effect of TC practice on measures associated with sensorimotor processing. In study 1, we evaluated TC’s effects on an oscillatory parameter associated with motor function, beta rhythm (15-30 Hz coherence, focusing specifically on beta rhythm intermuscular coherence (IMC, which is tightly coupled to beta corticomuscular coherence (CMC. We utilized electromyography (EMG to compare beta IMC in older TC practitioners with age-matched controls, as well as novices with advanced TC practitioners. Given previous findings of elevated, maladaptive beta coherence in older subjects, we hypothesized that increased TC practice would be associated with a monotonic decrease in beta IMC, but rather discovered that novice practitioners manifested higher beta IMC than both controls and advanced practitioners, forming an inverted U-shaped practice curve. This finding suggests that TC practice elicits complex changes in sensory and motor processes over the developmental lifespan of TC training. In study 2, we focused on somatosensory (e.g., tactile and proprioceptive responses to the Rubber Hand Illusion (RHI in a middle-aged TC group, assessing whether responses to the illusion became dampened with greater cumulative practice. As hypothesized, TC practice was associated with decreased likelihood to misattribute tactile stimulation during the RHI to the rubber hand, although there was no effect of TC practice on measures of proprioception or on subjective reports of ownership. These studies provide preliminary evidence that TC practice modulates beta network coherence in a non-linear fashion, perhaps as a result of the focus on not only efferent motor but also afferent sensory

    Tai Chi exercise, an ancient Chinese martial art, has drawn more and more attention for its health benefits. The purpose of the study was to identify the effects of a Sun-style Tai Chi exercise on arthritic symptoms (joint pain and stiffness), motivation for performing health behaviors, and the performance of health behaviors among older women with osteoarthritis. Total of 72 women with the mean age of 63 years old were recruited from outpatients clinic or public health centers according to the inclusion criteria and assigned randomly to either the Tai Chi exercise group or the control. A Sun-style Tai Chi exercise has been provided three times a week for the first two weeks, and then once a week for another 10 weeks. In 12 weeks of study period, 22 subjects in the Tai Chi exercise group and 21 subjects in the control group completed the posttest measure with the dropout rate of 41%. Outcome variables included arthritic symptoms measured by K-WOMAC, motivation for health behavior, and health behaviors. At the completion of the 12 week Tai Chi exercise, the Tai Chi group perceived significantly less joint pain (t=-2.19, p=0.03) and stiffness (t=-2.24, p=0.03), perceived more health benefits (t=2.67, p=0.01), and performed better health behaviors (t=2.35, p=0.02), specifically for diet behavior (t=2.06, p=0.04) and stress management (t=2.97, p=0.005). A Sun-style Tai Chi exercise was found as beneficial for women with osteoarthritis to reduce their perceived arthritic symptoms, improve their perception of health benefits to perform better health behaviors.

    The aim of this randomized trial was to compare the effects of Tai Chi with and without CBI on a primary outcome of reducing the fear of falling, and on secondary outcomes including encouraging better social engagement, improving self-perceived personal wellbeing, and achieving better mobility among elderly people with fear of falling. One hundred and twenty-two community-dwelling elderly people aged ≥ 65 were randomly assigned to either a Tai Chi or a Tai Chi plus CBI group. Participants' level of fear of falling, physical mobility, self-perceived personal wellbeing and social participation were compared before and after completing the 8-week intervention and then at a 2-month follow-up. The findings showed that Tai Chi both with and without CBI had a similar effect on reducing elderly people's fear of falling, but only Tai Chi plus CBI had a positive effect on participants' self-perceived personal wellbeing. Tai Chi both with and without CBI had no effect on participants' self-perceived social participation and mobility. Apart from a slight improvement in participants' self-perceived personal wellbeing, other outcome effects were similar for Tai Chi with and without CBI. This finding raises a question about the additive effects of combined intervention over Tai Chi alone in reducing elderly people's fear of falling. In view of the higher demand for resources and manpower to implement a combined intervention, further study is still required to confirm the potential additional benefits of this combined intervention prior to recommending it to community services.

    Previous studies provide evidence that aging is associated with the decline of memory function and alterations in the hippocampal (HPC) function, including functional connectivity to the medial prefrontal cortex (mPFC). In this study, we investigated if longitudinal (12-week) Tai Chi Chuan and Baduanjin practice can improve memory function and modulate HPC resting-state functional connectivity (rs-FC). Memory function measurements and resting-state functional magnetic resonance imaging (rs-fMRI) were applied at the beginning and the end of the experiment. The results showed that (1) the memory quotient (MQ) measured by the Wechsler Memory Scale-Chinese Revision significantly increased after Tai Chi Chuan and Baduanjin practice as compared with the control group, and no significant difference was observed in MQ between the Tai Chi Chuan and Baduanjin groups; (2) rs-FC between the bilateral hippocampus and mPFC significantly increased in the Tai Chi Chuan group compared to the control group (also in the Baduanjin group compared to the control group, albeit at a lower threshold), and no significant difference between the Tai Chi Chuan and Baduanjin groups was observed; (3) rs-FC increases between the bilateral hippocampus and mPFC were significantly associated with corresponding memory function improvement across all subjects. Similar results were observed using the left or right hippocampus as seeds. Our results suggest that both Tai Chi Chuan and Baduanjin may be effective exercises to prevent memory decline during aging.

    Physical inactivity is one of the major modifiable lifestyle risk factors for cardiovascular disease (CVD). This protocol aims to evaluate the effectiveness of Tai Chi versus brisk walking in reducing CVD risk factors. This is a randomized controlled trial with three arms, namely, Tai Chi group, walking group, and control group. The Tai Chi group will receive Tai Chi training, which consists of two 60-min sessions each week for three months, and self-practice for 30 min every day. The walking group will perform brisk walking for 30 min every day. The control group will receive their usual care. 246 subjects with CVD risk factors will be recruited from two outpatient clinics. The primary outcome is blood pressure. Secondary outcomes include fasting blood for lipid profile, sugar and glycated haemoglobin (HbA1c); body mass index, waist circumference, body fat percentage; perceived stress level and quality of life. Data collections will be conducted at baseline, 3-month, 6-month and 9-month. Generalized estimating equations model will be used to compare the changes in outcomes across time between groups. It is expected that both the Tai Chi and walking groups could maintain better health and have improved quality of life, and that Tai Chi will be more effective than brisk walking in reducing CVD risk factors.

    Full Text Available Objective. The purpose of this systematic review is to evaluate the evidence on the effect of Tai Chi for Parkinson’s disease (PD. Methods. Six electronic databases up to June 2014 were searched. The methodological quality was assessed with PEDro scale. Standardised mean difference and 95% confidence intervals of random-effects model were calculated. Results. Nine studies were included in our review. The aggregated results are in favor of Tai Chi on improving motor function (P=0.002 and balance (P<0.00001 in patients with PD. However, there is no sufficient evidence to support or refute the value of Tai Chi on improving gait velocity (P=0.11, stride length (P=0.21, or quality of life (P=0.40. And there is no valid evidence in follow-up effects of Tai Chi for PD. Conclusion. The current results suggest that Tai Chi can significantly improve the motor function and balance in patients with PD, but there is indeed not enough evidence to conclude that Tai Chi is effective for PD because of the small treatment effect, methodological flaws of eligible studies, and insufficient follow-up. Consequently, high-quality studies with long follow-up are warranted to confirm current beneficial findings.

    Knee osteoarthritis (OA) causes pain and long-term disability with annual healthcare costs exceeding $185 billion in the United States. Few medical remedies effectively influence the course of the disease. Finding effective treatments to maintain function and quality of life in patients with knee OA is one of the national priorities identified by the Institute of Medicine. We are currently conducting the first comparative effectiveness and cost-effectiveness randomized trial of Tai Chi versus a physical-therapy regimen in a sample of patients with symptomatic and radiographically confirmed knee OA. This article describes the design and conduct of this trial. A single-center, 52-week, comparative effectiveness randomized controlled trial of Tai Chi versus a standardized physical-therapy regimen is being conducted at an urban tertiary medical center in Boston, Massachusetts. The study population consists of adults ≥ 40 years of age with symptomatic and radiographic knee OA (American College of Rheumatology criteria). Participants are randomly allocated to either 12 weeks of Tai Chi (2x/week) or Physical Therapy (2x/week for 6 weeks, followed by 6 weeks of rigorously monitored home exercise). The primary outcome measure is pain (Western Ontario and McMaster Universities WOMAC) subscale at 12 weeks. Secondary outcomes include WOMAC stkiffness and function domain scores, lower extremity strength and power, functional balance, physical performance tests, psychological and psychosocial functioning, durability effects, health related quality of life, and healthcare utilization at 12, 24 and 52 weeks. This study will be the first randomized comparative-effectiveness and cost-effectiveness trial of Tai Chi versus Physical Therapy in a large symptomatic knee OA population with long-term follow up. We present here a robust and well-designed randomized comparative-effectiveness trial that also explores multiple outcomes to elucidate the potential mechanisms of mind

    To examine feasibility, qualitative feedback and satisfaction associated with a 4-session introduction to Tai Chi for veterans with post-traumatic stress symptoms. We observed and reported recruitment and retention rates, participant characteristics, adherence, and satisfaction across 2 cohorts. We also examined qualitative feedback provided by questionnaires, focus groups and individual interviews. Rates of recruitment and retention, focus group and individual feedback interviews, self-reported satisfaction. 17 veterans with post-traumatic stress symptoms. Almost 90% (17/19) of those eligible following the telephone screen enrolled in the programme. Three-quarters (76.4%) of the participants attended at least 3 of the 4 Tai Chi sessions. Qualitative data analysis revealed themes indicating favourable impressions of the Tai Chi sessions. In addition, participants reported feeling very engaged during the sessions, and found Tai Chi to be helpful for managing distressing symptoms (ie, intrusive thoughts, concentration difficulties, physiological arousal). Participants also reported high satisfaction: 93.8% endorsed being very or mostly satisfied with the programme. All participants (100%) indicated that they would like to participate in future Tai Chi programmes and would recommend it to a friend. Tai Chi appears to be feasible and safe for veterans with symptoms of post-traumatic stress disorder (PTSD), is perceived to be beneficial and is associated with high rates of satisfaction. This study highlights the need for future investigation of Tai Chi as a novel intervention to address symptoms of PTSD. Published by the BMJ Publishing Group Limited.

    Full Text Available Obesity is a major health problem in the USA, especially in minority populations over the age of 60 years, and the aging process can cause adverse effects on physical function. Previous research has shown that Tai Chi, resistance training (RT, and diet result in overall health improvements. However, the combination of these specific interventions has yet to be translated to obese older women in an urban setting. The purpose of this study was to examine a combined intervention on the primary outcomes of physical function and body composition. Using a nonrandomized design, 26 obese women (65.2±8.1 years completed a 12-week intervention; participants were assigned to an intervention (EXD group or a control (CON group. The EXD group (n=17 participated in Tai Chi, RT, and a dietary session. The CON group (n=9 was asked to continue their normal lifestyle. Timed up and go (TUG time was reduced by 0.64±2.1 seconds (P=0.04 in the EXD group while the CON group saw a borderline significant increase of 0.71 sec (P=0.051. The combined intervention helped improve performance on TUG time, but there were no significant increases in other body composition or function measures.

    Objective. To investigate the effects of sitting Tai Chi on muscle strength, balance control, and quality of life (QOL) among survivors with spinal cord injuries (SCI). Methods. Eleven SCI survivors participated in the sitting Tai Chi training (90 minutes/session, 2 times/week for 12 weeks) and eight SCI survivors acted as controls. Dynamic sitting balance was evaluated using limits of stability test and a sequential weight shifting test in sitting. Handgrip strength was also tested using a hand-held dynamometer. QOL was measured using the World Health Organization's Quality of Life Scale. Results. Tai Chi practitioners achieved significant improvements in their reaction time (P = 0.042); maximum excursion (P = 0.016); and directional control (P = 0.025) in the limits of stability test after training. In the sequential weight shifting test, they significantly improved their total time to sequentially hit the 12 targets (P = 0.035). Significant improvement in handgrip strength was also found among the Tai Chi practitioners (P = 0.049). However, no significant within and between-group differences were found in the QOL outcomes (P > 0.05). Conclusions. Twelve weeks of sitting Tai Chi training could improve the dynamic sitting balance and handgrip strength, but not QOL, of the SCI survivors.

    Full Text Available Peripheral neuropathy and loss of somatosensation in older adults with type 2 diabetes can increase risk of falls and disability. In nondiabetic older adult population Tai Chi has been shown to enhance balance and fitness through improvements in somatosensation and neuromuscular control, and it is unclear if Tai Chi would elicit similar benefits in older adults with diabetes. Therefore, the purpose of this study was to investigate the effects of an 8-week, three-hour-per-week Tai Chi intervention on peripheral somatosensation in older adults with type 2 diabetes. Participants were eight Hispanic older adults with type 2 diabetes who participated in the Tai Chi intervention and a convenience sample of Hispanic older adults as a referent group. Baseline and postintervention assessments included ankle proprioception, foot tactile sense, plantar pressure distribution, balance, and fitness. After intervention, older adults with type 2 diabetes showed significant improvements in ankle proprioception and fitness and decreased plantar pressure in the forefoot, with no statistical effect noted in balance or tactile sensation. Study results suggest that Tai Chi may be beneficial for older adults with diabetes as it improves ankle proprioception; however, study findings need to be confirmed in a larger sample size randomized controlled trial.

    Cardiovascular disease (CVD) is a leading cause of morbidity and mortality worldwide. Psychological risk factors such as stress, anxiety and depression are known to play a significant and independent role in the development and progression of CVD and its risk factors. Tai Chi has been reported to be potentially effective for health and well-being. It is of value to assess the effectiveness and safety of Tai Chi on psychological well-being and quality of life in people with CVD and/or cardiovascular risk factors. We will include all relevant randomised controlled trials on Tai Chi for stress, anxiety, depression, psychological well-being and quality of life in people with CVD and cardiovascular risk factors. Literature searching will be conducted until 31 December 2016 from major English and Chinese databases. Two authors will conduct data selection and extraction independently. Quality assessment will be conducted using the risk of bias tool recommended by the Cochrane Collaboration. We will conduct data analysis using Cochrane's RevMan software. Forest plots and summary of findings tables will illustrate the results from a meta-analysis if sufficient studies are identified. Ethics approval is not required as this study will not involve patients. The results of this study will be submitted to a peer-reviewed journal for publication, to inform both clinical practice and further research on Tai Chi and CVDs. This review will summarise the evidence on Tai Chi for psychological well-being and quality of life in people with CVD and their risk factors. We anticipate that the results of this review would be useful for healthcare professionals and researchers on Tai Chi and CVDs.

    Stress is a major problem in today's fast-paced society and can lead to serious psychosomatic complications. The ancient Chinese mind-body exercise of Tai Chi may provide an alternative and self-sustaining option to pharmaceutical medication for stressed individuals to improve their coping mechanisms. The protocol of this study is designed to evaluate whether Tai Chi practice is equivalent to standard exercise and whether the Tai Chi group is superior to a wait-list control group in improving stress coping levels. This study is a 6-week, three-arm, parallel, randomized, clinical trial designed to evaluate Tai Chi practice against standard exercise and a Tai Chi group against a nonactive control group over a period of 6 weeks with a 6-week follow-up. A total of 72 healthy adult participants (aged 18-60 years) who are either Tai Chi naïve or have not practiced Tai Chi in the past 12 months will be randomized into a Tai Chi group (n = 24), an exercise group (n = 24) or a wait-list group (n = 24). The primary outcome measure will be the State Trait Anxiety Inventory with secondary outcome measures being the Perceived Stress Scale 14, heart rate variability, blood pressure, Short Form 36 and a visual analog scale. The protocol is reported using the appropriate Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) items.

    Osteoporosis is a degenerative bone disease predominantly in postmenopausal women. Green tea polyphenols (GTP) and Tai Chi (TC) have been shown to be beneficial on human bone health. This study examined the efficacy of GTP and TC on mitigation of oxidative damage in postmenopausal women with osteopenia. A 6-month randomized and placebo-controlled clinical trial was conducted in 171 postmenopausal women with osteopenia, who were recruited from Lubbock County, Texas. These participants were treated with placebo, GTP (500 mg daily), placebo + TC (60-minute group exercise, 3 times/week), or GTP (500 mg daily) + TC (60-minute group exercise, 3 times/week), respectively. Their blood and urine samples were collected at the baseline, 1-, 3- and 6-months during intervention for assessing levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG), an oxidative DNA damage biomarker, and concentrations of serum and urine GTP components. The elevated concentrations of serum and urinary GTP components demonstrated a good adherence for the trial. A significant reduction of urinary 8-OHdG concentrations was found in all three treated groups during 3-month (Pstress, a putative mechanism for osteoporosis in postmenopausal women, and more importantly, working in an additive manner, which holds the potential as alternative tools to improve bone health in this population.

    The aim of this study was to compare experts to naïve practitioners in rating the beauty and the technical quality of a Tai Chi sequence observed in video-clips (of high and middle level performances). Our hypothesis are: i) movement evaluation will correlate with the level of skill expressed in the kinematics of the observed action but ii) only experts will be able to unravel the technical component from the aesthetic component of the observed action. The judgments delivered indicate that both expert and non-expert observers are able to discern a good from a mediocre performance; however, as expected, only experts discriminate the technical from the aesthetic component of the action evaluated and do this independently of the level of skill shown by the model (high or middle level performances). Furthermore, the judgments delivered were strongly related to the kinematic variables measured in the observed model, indicating that observers rely on specific movement kinematics (e.g. movement amplitude, jerk and duration) for action evaluation. These results provide evidence of the complementary functional role of visual and motor action representation in movement evaluation and underline the role of expertise in judging the aesthetic quality of movements.

    [Purpose] The purpose of this study was to examine the effects of Tai Chi (TC)-based exercise on dynamic postural control during obstacle negotiation by subjects with mild or moderate Parkinson's disease (PD). [Subjects] Twelve subjects (mean age, 65.3±6.1 years) diagnosed with idiopathic PD were enrolled for this study. [Methods] All the subjects were tested a week before and 12 weeks after the initiation of the TC exercise. In the test, they were instructed to negotiate an obstacle from the position of quiet stance at a normal speed. They were trained with TC exercise that emphasized multidirectional shift in weight bearing from bilateral to unilateral support, challenging the postural stability, three times per week for 12 weeks. Center of pressure (COP) trajectory variables before and after TC exercise were measured using two force plates. [Results] A comparison of the results between pre- and post-intervention showed a statistically significant improvement in anteroposterior and mediolateral displacement of COP. [Conclusion] Twelve weeks of TC exercise may be an effective and safe form of stand-alone behavioral intervention for improving the dynamic postural stability of patients with PD.

To compare the shoulder mobility, muscular strength, and quality of life (QOL among breast cancer survivors with and without Tai Chi (TC Qigong training to those of healthy individuals and to explore the associations between shoulder impairments and QOL in breast cancer survivors with regular TC Qigong training. Methods. Eleven breast cancer survivors with regular TC Qigong training, 12 sedentary breast cancer survivors, and 16 healthy participants completed the study. Shoulder mobility and rotator muscle strength were assessed by goniometry and isokinetic dynamometer, respectively. QOL was assessed using the Functional Assessment of Cancer Therapy-Breast (FACT-B questionnaire. Results. Goniometric measurements of the active range of motion in the flexion, abduction, and hand-behind-the-back directions were similar among the three groups. The TC Qigong-trained breast cancer survivors had significantly higher isokinetic peak torques of the shoulder rotator muscles (at than untrained survivors, and their isokinetic shoulder muscular strength reached the level of healthy individuals. Greater shoulder muscular strength was significantly associated with better functional wellbeing in breast cancer survivors with TC Qigong training. However, no significant between-group difference was found in FACT-B total scores. Conclusions. TC Qigong training might improve shoulder muscular strength and functional wellbeing in breast cancer survivors.

    One of the effects of diabetes mellitus (DM), peripheral neuropathy, affects the sensation in the feet and can increase the chance of falling. The purpose of the study was to investigate the effect of 8 weeks of Tai Chi (TC) training combined with mental imagery (MI) on improving balance in people with diabetes and an age matched control group. Seventeen healthy subjects and 12 diabetic sedentary subjects ranging from 40-80 years of age were recruited. All subjects in both groups attended a Yang style of TC class using MI strategies, 2 sessions a week for 8 weeks. Each session was one hour long. Measures were taken using a balance platform test, an Activities-specific Balance Confidence (ABC) Scale, a one leg standing test (OLS), functional reach test (FRT) and hemoglobin A1C. These measures were taken twice, pre and post-study, for both groups. Both groups experienced significant improvements in ABC, OLS, FRT (Pbalance platform test demonstrated improvement in balance in all different tasks with no significant change between groups. There was no significant change in HbA1C for the diabetic group. All results showed an improvement in balance in the diabetic and the control groups; however, no significant difference between the groups was observed. Since the DM group had more problems with balance impairment at baseline than the control, the diabetic group showed the most benefit from the TC exercise.

    Objectives :To examine the effects of 16 - week Tai Chi (TC) training on postural stability and associated physiological factors in older subjects,forty elderly individuals (aged ≥ 60 years) living in the community were randomly placed into either the TC intervention group ( n = 22) or the control group (n = 18). The former underwent a supervised TC exercise program for 16 weeks, while the latter received general education for a comparable time period. Measurements:Postural stability was assessed by timed stance tests in single - leg stance with the eyes open (SLO) or closed (SLC), and tandem stance with the eyes closed (TSC). Proprioceptive function was evaluated by measuring ankle and knee kinesthesia. The maximum concentric strength of the knee flexors and extensors,ankle plantarflexors and dorsiflexors was measured by isokinetic dynamometer. Moreover, the reaction time of different muscles in the lower extremity was also examined by measuring the onset latency of the muscles to perturbations on the ankle joint using an electromyography system. Results :After the 16-week TC intervention, significant TC training effects were gained on knee kinesthesia, knee flexor strength, latency of semitendinous muscle, and postural stability in SLO. For the other measures,no significant training effects were found. Conclusions: The 16 - week TC intervention was found to be beneficial for the improvement of postural stability and associated physiological factors. However, there are discrepancies in TC training effects on different factors in the sensorimotor system.

    Full Text Available Abstract Background Falls are a significant public health problem. Thirty to fifty percent of the elderly of 65 years and older fall each year. Falls are the most common type of accident in this age group and can result in fractures and subsequent disabilities, increased fear of falling, social isolation, decreased mobility, and even an increased mortality. Several forms of exercise have been associated with a reduced risk of falling and with a wide range of physiological as well as psychosocial health benefits. Tai Chi Chuan seems to be the most promising form of exercise in the elderly, but the evidence is still controversial. In this article the design of a randomized clinical trial is presented. The trial evaluates the effect of Tai Chi Chuan on fall prevention and physical and psychological function in older adults. Methods/Design 270 people of seventy years and older living at home will be identified in the files of the participating general practitioners. People will be asked to participate when meeting the following inclusion criteria: have experienced a fall in the preceding year or suffer from two of the following risk factors: disturbed balance, mobility problems, dizziness, or the use of benzodiazepines or diuretics. People will be randomly allocated to either the Tai Chi Chuan group (13 weeks, twice a week or the no treatment control group. The primary outcome measure is the number of new falls, measured with a diary. The secondary outcome measures are balance, fear of falling, blood pressure, heart rate, lung function parameters, physical activity, functional status, quality of life, mental health, use of walking devices, medication, use of health care services, adjustments to the house, severity of fall incidents and subsequent injuries. Process parameters will be measured to evaluate the Tai Chi Chuan intervention. A cost-effectiveness analysis will be carried out alongside the evaluation of the clinical results. Follow

    A growing number of cancer survivors suffer high levels of distress, depression and stress, as well as sleep disturbance, pain and fatigue. Two different mind-body interventions helpful for treating these problems are Mindfulness-Based Cancer Recovery (MBCR) and Tai Chi/Qigong (TCQ). However, while both interventions show efficacy compared to usual care, they have never been evaluated in the same study or directly compared. This study will be the first to incorporate innovative design features including patient choice while evaluating two interventions to treat distressed cancer survivors. It will also allow for secondary analyses of which program best targets specific symptoms in particular groups of survivors, based on preferences and baseline characteristics. The design is a preference-based multi-site randomized comparative effectiveness trial. Participants (N=600) with a preference for either MBCR or TCQ will receive their preferred intervention; while those without a preference will be randomized into either intervention. Further, within the preference and non-preference groups, participants will be randomized into immediate intervention or wait-list control. Total mood disturbance on the Profile of mood states (POMS) post-intervention is the primary outcome. Other measures taken pre- and post-intervention and at 6-month follow-up include quality of life, psychological functioning, cancer-related symptoms and physical functioning. Exploratory analyses investigate biomarkers (cortisol, cytokines, blood pressure/Heart Rate Variability, telomere length, gene expression), which may uncover potentially important effects on key biological regulatory and antineoplastic functions. Health economic measures will determine potential savings to the health system. Copyright © 2017 Elsevier Inc. All rights reserved.

    Stress can affect health. There is a growing need for the evaluation and application of professional stress management options, i.e, stress reduction. Mind/body medicine serves this goal, e.g, by integrating self-care techniques into medicine and health care. Tai Chi (TC) can be classified as such a mind/body technique, potentially reducing stress and affecting physical as well as mental health parameters, which, however, has to be examined further. We conducted a prospective, longitudinal pilot study over 18 weeks for the evaluation of subjective and objective clinical effects of a Yang style TC intervention in young adults (beginners) by measuring physiological (blood pressure, heart rate, saliva cortisol) and psychological (SF-36, perceived stress, significant events) parameters, i.e, direct or indirect indicators of stress and stress reduction, in a non-randomised/-controlled, yet non-selected cohort (n=21) by pre-to-post comparison and in follow-up. SF-36 values were also compared with the age-adjusted norm population, serving as an external control. Additionally, we measured diurnal cortisol profiles in a cross-sectional sub-study (n=2+2, pre-to-post), providing an internal random control sub-sample. Only nine participants completed all measurements. Even so, we found significant (pstress reduction. A significant decrease in perceived mental stress (post) proved even highly significant (pstress perception declined to a much lesser degree. Significant improvements were also detected for the SF-36 dimensions general health perception, social functioning, vitality, and mental health/psychological well-being. Thus, the summarized mental health measures all clearly improved, pointing towards a predominantly psychological impact of TC. Subjective health increased, stress decreased (objectively and subjectively) during TC practice. Future studies should confirm this observation by rigorous methodology and by further combining physical and psychological measurements

    Full Text Available BACKGROUND: Osteoporosis is a degenerative bone disease predominantly in postmenopausal women. Green tea polyphenols (GTP and Tai Chi (TC have been shown to be beneficial on human bone health. This study examined the efficacy of GTP and TC on mitigation of oxidative damage in postmenopausal women with osteopenia. METHODS: A 6-month randomized and placebo-controlled clinical trial was conducted in 171 postmenopausal women with osteopenia, who were recruited from Lubbock County, Texas. These participants were treated with placebo, GTP (500 mg daily, placebo + TC (60-minute group exercise, 3 times/week, or GTP (500 mg daily + TC (60-minute group exercise, 3 times/week, respectively. Their blood and urine samples were collected at the baseline, 1-, 3- and 6-months during intervention for assessing levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG, an oxidative DNA damage biomarker, and concentrations of serum and urine GTP components. RESULTS: The elevated concentrations of serum and urinary GTP components demonstrated a good adherence for the trial. A significant reduction of urinary 8-OHdG concentrations was found in all three treated groups during 3-month (P<0.001 and 6-month (P<0.001 intervention, as compared to the placebo group. The significant time- and dose-effects on mitigation of the oxidative damage biomarker were also found for GTP, TC, and GTP+TC intervened groups. CONCLUSION: Our study demonstrated that GTP and TC interventions were effective strategies of reducing the levels of oxidative stress, a putative mechanism for osteoporosis in postmenopausal women, and more importantly, working in an additive manner, which holds the potential as alternative tools to improve bone health in this population.

This study aimed to test the efficacy of the “Tai Chi for Diabetes” form, developed to address health-related problems in diabetes, including mobility and physical function. Thirty-eight older adults with stable type 2 diabetes were randomized to Tai Chi or sham exercise, twice a week for 16 weeks. Outcomes included gait, balance, musculoskeletal and cardiovascular fitness, self-reported activity and quality of life. Static and dynamic balance index (−5.8 ± 14.2; p = 0.03 and maximal gait speed (6.2 ± 11.6%; p = 0.005 improved over time, with no significant group effects. There were no changes in other measures. Non-specific effects of exercise testing and/or study participation such as outcome expectation, socialization, the Hawthorne effect, or unmeasured changes in health status or compliance with medical treatment may underlie the modest improvements in gait and balance observed in this sham-exercise-controlled trial. This Tai Chi form, although developed specifically for diabetes, may not have been of sufficient intensity, frequency, or duration to effect positive changes in many aspects of physiology or health status relevant to older people with diabetes.Keywords: Tai Chi, Type 2 diabetes, physical function

    Full Text Available Tai Chi and walking are both moderate-intensity physical activity (PA that can be easily practiced in daily life. The objective of the study was to determine the effects of these two PAs on weight loss, metabolic syndrome parameters, and bone mineral density (BMD in Chinese adults. We randomized 374 middle-aged subjects (45.8 ± 5.3 years into 12-week training (45 minutes per day, 5 days per week of Tai Chi (n=124 or self-paced walking (n=121 or control group (n=129. On average, Tai Chi and walking groups lost 0.50 and 0.76 kg of body weight and 0.47 and 0.59 kg of fat mass after intervention, respectively. The between-group difference of waist circumference (WC and fasting blood glucose (FBG was −3.7 cm and −0.18 mmol/L for Tai Chi versus control and −4.1 cm and −0.22 mmol/L for walking versus control. No significant differences were observed regarding lean mass, blood pressure, triglycerides, total cholesterol, high-density and low-density lipoprotein cholesterol, and BMD compared to control. Change in lean mass, not fat mass or total weight loss, was significantly correlated to the change in BMD. Our results suggest that both of these two PAs can produce moderate weight loss and significantly improve the WC and FBG in Hong Kong Chinese adults, with no additional effects on BMD.

    Purpose To test the feasibility and preliminary effectiveness of a tai chi qigong program with the assistance of elderly neighborhood volunteers in strengthening social networks and enhancing the psychosocial well-being of hidden elderly. Patients and methods “Hidden elderly” is a term used to describe older adults who are socially isolated and refuse social participation. This pilot randomized controlled trial recruited 48 older adults aged 60 or above who did not engage in any social activity. They were randomized into tai chi qigong (n=24) and standard care control (n=24) groups. The former group underwent a three-month program of two 60-minute sessions each week, with the socially active volunteers paired up with them during practice. Standard care included regular home visits by social workers. Primary outcomes were assessed by means of the Lubben social network and De Jong Gieveld loneliness scales, and by a revised social support questionnaire. Secondary outcomes were covered by a mental health inventory and the Rosenberg self-esteem scale, and quality of life by using the 12-Item Short Form Health Survey. Data was collected at baseline, and at three and six months thereafter. Results The generalized estimating equations model revealed general improvement in outcomes among participants on the tai chi qigong program. In particular, participants reported a significantly greater improvement on the loneliness scale (B=−1.32, 95% confidence interval [CI] −2.54 to −0.11, P=0.033) and the satisfaction component of the social support questionnaire (B=3.43, 95% CI 0.10–6.76, P=0.044) than the control group. Conclusion The pilot study confirmed that tai chi qigong with elderly neighborhood volunteers is a safe and feasible social intervention for hidden elderly. Its potential benefits in improving social and psychological health suggest the need for a full-scale randomized controlled trial to reveal its empirical effects. PMID:28115837

    Aging is typically associated with progressive multi-system impairment that leads to decreased physical and cognitive function and reduced adaptability to stress. Due to its capacity to characterize complex dynamics within and between physiological systems, the emerging field of complex systems biology and its array of quantitative tools show great promise for improving our understanding of aging, monitoring senescence, and providing biomarkers for evaluating novel interventions, including promising mind-body exercises, that treat age-related disease and promote healthy aging. An ongoing, two-arm randomized clinical trial is evaluating the potential of Tai Chi mind-body exercise to attenuate age-related loss of complexity. A total of 60 Tai Chi-naïve healthy older adults (aged 50-79) are being randomized to either six months of Tai Chi training (n=30), or to a waitlist control receiving unaltered usual medical care (n=30). Our primary outcomes are complexity-based measures of heart rate, standing postural sway and gait stride interval dynamics assessed at 3 and 6months. Multiscale entropy and detrended fluctuation analysis are used as entropy- and fractal-based measures of complexity, respectively. Secondary outcomes include measures of physical and psychological function and tests of physiological adaptability also assessed at 3 and 6months. Results of this study may lead to novel biomarkers that help us monitor and understand the physiological processes of aging and explore the potential benefits of Tai Chi and related mind-body exercises for healthy aging.

    Objective was to investigate the effects of Tai Chi exercise on nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H2S) levels, and blood pressure (BP) in patients with essential hypertension (EH). EH patients were assigned to the Tai Chi exercise group (HTC, n = 24), and hypertension group (HP, n = 16) by patients' willingness. Healthy volunteers matched for age and gender were recruited as control (NP, n = 16). HTC group performed Tai Chi (60 min/d, 6 d/week) for 12 weeks. Measurements (blood glucose, cholesterol, NO, CO, H2S and BP) were obtained at week 0, 6, and 12. SBP, MAP, and low-density lipoprotein cholesterol levels decreased, and high-density lipoprotein cholesterol levels increased by week 12 in the HTC group (all p < 0.05 versus baseline). Plasma NO, CO, and H2S levels in the HTC group were increased after 12 weeks (all p < 0.05 versus baseline). SBP, DBP and MAP levels were significantly lower in the HTC than in the HP group (all p < 0.05). However, no changes were observed in the HP and NP groups. Correlations were observed between changes in SBP and changes in NO, CO and H2S (r = -0.45, -0.51 and -0.46, respectively, all p < 0.05), and between changes in MAP and changes in NO, CO and H2S (r = -0.36, -0.45 and -0.42, respectively, all p < 0.05). In conclusion, Tai Chi exercise seems to have beneficial effects on BP and gaseous signaling molecules in EH patients. However, further investigation is required to understand the exact mechanisms underlying these observations, and to confirm these results in a larger cohort.

    Although SARS had been with a controversial topic for a decade at the time of this study, numerous SARS survivors had not yet physically, psychologically or socially recovered from the aftermath of SARS. Among chronically ill patients, the use of complementary and alternative medicine (CAM) is reported to be widespread. However, extremely little is known about the use of CAM by SARS survivors in the post-SARS period and even less is known about how the use of CAM is related to the unpleasant social and medical-treatment experiences of SARS survivors, their eagerness to re-establish social networks, and their awareness to prepare for future epidemics. To investigate the motivations for practising tai chi among SARS survivors in post-SARS Hong Kong. Using a qualitative approach, I conducted individual semi-structured interviews with 35 SARS survivors, who were purposively sampled from a tai chi class of a SARS-patient self-help group in Hong Kong. Health concerns and social experiences motivated the participants to practise tai chi in post-SARS Hong Kong. Experiencing health deterioration in relation to SARS-associated sequelae, coping with unpleasant experiences during follow-up biomedical treatments, a desire to regain an active role in recovery and rehabilitation, overcoming SARS-associated stigmas by establishing a new social network and preparing for potential future stigmatization and discrimination were the key motivators for them. The participants practised tai chi not only because they sought to improve their health but also because it provided a crucial social function and meaning to them. © 2014 John Wiley & Sons Ltd.

    [Purpose] There is insufficient evidence related to exercise programs that are safe and efficacious for pregnant women with abnormal glucose metabolism. Tai Chi Yuttari-exercise is an exercise program with validated safety and efficacy in improving physical function in the elderly. In this study, we investigated this program’s inhibitory effects on plasma glucose elevation when it was adapted to a pregnancy model. [Subjects and Methods] Twelve 18- to 19-year-old females without a history of pregnancy were randomly assorted into two groups: an intervention group, for which six subjects were outfitted with mock-pregnancy suits and asked to perform Tai Chi Yuttari-exercise, and a control group who did not perform exercise. The intervention group had a mean Borg Scale score of 11.1 ± 0.9 during the exercise. [Results] No significant intragroup differences were observed in fasting, baseline, or post-intervention/observation plasma glucose levels. On the other hand, the intergroup change in plasma glucose levels after intervention/observation was significant when comparing the intervention and control groups: −1.66 ± 7.0 and 9.42 ± 6.57 mg/dl, respectively. [Conclusion] Tai Chi Yuttari-exercise appears to effectively inhibit plasma glucose elevation at intensity and movement levels that can be safely applied to pregnant women with abnormal glucose metabolism.

    Full Text Available One of the most fragile stratums of every society is the people with certain disabilities, especially educable mentally retarded children. Some of the most tangible difficulties of these people are seen in their perceptual and motional abilities (coordination, balance, atmospheric awareness, time awareness, physical awareness and sense of direction. Overcoming these inabilities requires the integration of environmental information and decision making for performance of a special function. The objective of the present research is to investigate the effects of eight weeks of Tai-Chi exercises on status parameters of Kyphosis and balance among educable mentally retarded children. The research sample is consisted of 30 educable mentally retarded children suffering from Kyphosis abnormality. The sample individuals were selected from welfare centers of Tehran. After selection of samples, prior and post to execution of the protocol, the individuals were measured in terms of Kyphosis angle, chest expansion, coefficient of Delmas, spine extension and static and dynamic balances respectively through flexible rulers, tape measure, stoke test and Y test. The educable mentally retarded children were assigned to two 15 individual groups of experimental (age average of 11.6 years; average height of 142.30; average weight of 39.26kg and control (age average of 11.06; height average of 139.83 and weight average of 35.86kg. The subjects of the experimental group were participated in an 8 week course of Tai-Chi exercises in three weekly 45 minute sessions. These exercises included a 10 minute warm-up, 30 minutes of Tai-Chi movements and 5 minutes of cool-down. During this time, the subjects of the control group were not incorporated into any exercise. By the use of the Shapiro-Wilk test, the normality of data distribution was investigated and approved. Also the Leon test was used for investigation of equality of the variances.

    Given the current necessity of retaining qualified nurses, a self-care program consisting of Yoga, Tai Chi, Meditation classes, and Reiki healing sessions was designed for a university-based hospital. The effectiveness of these interventions was evaluated using self-care journals and analyzed using a Heideggerian phenomenological approach. Outcomes of the self-care classes described by nurses included: (a) noticing sensations of warmth, tingling, and pulsation which were relaxing, (b) becoming aware of an enhanced problem solving ability, and (c) noticing an increased ability to focus on patient needs. Hospitals willing to invest in self-care options for nurses can anticipate patient and work related benefits.

    2012-12-01

    Full Text Available Abstract Background Women with cancer are significantly more likely to fall than women without cancer placing them at higher risk of fall-related fractures, other injuries and disability. Currently, no evidence-based fall prevention strategies exist that specifically target female cancer survivors. The purpose of the GET FIT (Group Exercise Training for Functional Improvement after Treatment trial is to compare the efficacy of two distinct types of exercise, tai chi versus strength training, to prevent falls in women who have completed treatment for cancer. The specific aims of this study are to: 1 Determine and compare the efficacy of both tai chi training and strength training to reduce falls in older female cancer survivors, 2 Determine the mechanism(s by which tai chi and strength training each reduces falls and, 3 Determine whether or not the benefits of each intervention last after structured training stops. Methods/Design We will conduct a three-group, single-blind, parallel design, randomized controlled trial in women, aged 50–75 years old, who have completed chemotherapy for cancer comparing 1 tai chi 2 strength training and 3 a placebo control group of seated stretching exercise. Women will participate in supervised study programs twice per week for six months and will be followed for an additional six months after formal training stops. The primary outcome in this study is falls, which will be prospectively tracked by monthly self-report. Secondary outcomes are maximal leg strength measured by isokinetic dynamometry, postural stability measured by computerized dynamic posturography and physical function measured by the Physical Performance Battery, all measured at baseline, 3, 6 and 12 months. The sample for this trial (N=429, assuming 25% attrition will provide adequate statistical power to detect at least a 47% reduction in the fall rate over 1 year by being in either of the 2 exercise groups versus the control group.

    The particle paths of the Lagrangian flow field between two cylinders simulate well the spiral arms of Galaxy M51 image [1] and the interface curve of the Yin-Yang balance in the ancient Tai-Chi diagram [2]. The particle paths of the Lagrangian flow field involve four parameters. The normalization of the system of equations signifi-cantly simplifies the formulation of the flow process and reduces the original four parameters to only one pa-rameter. Furthermore it provides the similarity between the formulation of the spiral arms of Galaxy M51 and that of the interface curve of the Yin-Yang balance in the ancient Tal-Chi diagram.

    Secondary analysis of a randomized controlled trial. This secondary analysis aims to examine associations of improvement of chronic neck pain with patients' and intervention-related characteristics. Previous research has found that Tai Chi and neck exercises significantly improved chronic nonspecific neck pain; however, the factors for treatment success remain unclear. Subjects with chronic nonspecific neck pain were randomly assigned to 12 weeks of group Tai Chi or conventional neck exercises, and they attended 12 weekly sessions of 60 to 90 minutes. The interventions included exercises to improve body awareness, that is, interoceptive and postural awareness. A linear forward stepwise regression analysis was conducted to examine associations with improvements in neck pain intensity. Potential predictor variables included baseline pain, age, sex, the type of intervention, attendance rate and home practice duration, and changes in psychological well-being, perceived stress, and postural and interoceptive awareness during the study. Overall 75 patients were randomized into Tai Chi or conventional exercises, with the majority being women (78.7%). Participants reported an average pain intensity of 50.7 ± 20.4 mm visual analog scale at baseline, and the average reduction of pain intensity in both groups was 21.4 ± 21.3 mm visual analog scale. Regression analysis revealed that reductions in pain intensity from baseline to 12 weeks were predicted by higher pain intensity at baseline (r = 0.226, P < 0.001), a decrease in anxiety (r = 0.102, P = 0.001), and an increase in postural awareness (r = 0.078, P = 0.0033), explaining a total of 40.6% of variance. Neck pain improvement was significantly associated with changes in postural awareness in subject with chronic nonspecific neck pain independent of treatment characteristics. Training of postural awareness might be an important mechanism of action of different exercise-based interventions

    2010-01-01

    The purpose of this integrative review is to analyze the current research literature on Tai Chi (TC) and its potential effect on balance and prevention of falls in older adults. The evidence for improving balance is somewhat conflicting because few research studies identify which balance exercises are effective. The question of how TC achieves improvements in balance remains. To promote functional independence and improve quality of life in the later years of one's life, it is important to improve balance and prevent falls in older adults. TC poses challenges related to the complexity of the practice. By reviewing the current research literature on TC focusing on balance and falls in older adults, strategies may be developed to incorporate TC to improve balance and modify the known risk factors for falling. This article also discusses potential applications and limitations of the current research.

    Obesity, metabolic syndrome, dyslipidemia, and poor quality of life are common conditions associated with hypertension, and incidence of hypertension is age dependent. However, an effective program to prevent hypertension and to improve biomedical factors and quality of life has not been adequately examined or evaluated in Chinese older adults. This study aims to examine the effectiveness of a Tai Chi program to improve health status in participants with hypertension and its related risk factors such as dyslipidemia, hyperglycemia, and quality of life in older adults in China. A randomized study design was used. At the conclusion of the intervention, 266 patients remained in the study. Blood pressure and biomedical factors were measured according to the World Diabetes Association standard 2002. A standardized quality-of-life measure was used to measure health-related quality of life. It was found that a Tai Chi program to improve hypertension in older adults is effective in reducing blood pressure and body mass index, maintaining normal renal function, and improving physical health of health-related quality of life. It did not improve existing metabolic syndrome levels, lipid level (dyslipidemia) or fasting glucose level (hyperglycemia), to prevent further deterioration of the biomedical risk factors. In conclusion, Tai Chi is effective in managing a number of risk factors associated with hypertension in Chinese older adults. Future research should examine a combination of Tai Chi and nutritional intervention to further reduce the level of biomedical risks.

    In recent decades, the evidence supporting the physical and mental health benefits of holistic movement practices such as yoga and t'ai chi have become increasingly established. Consequently, investigating the participation prevalence and patterns of these practices is a relevant pursuit in the public health field. Few studies have provided population-level assessment of participation rates, however, and even fewer have focused on patterns over time. The purpose of this study was to examine participation prevalence and trends in yoga/Pilates and t'ai chi/qigong over a ten-year period in a nationally representative sample of Australians aged 15 years and over, with particular attention to sex and age. A secondary purpose was to juxtapose these findings with participation trends in traditional fitness activities over the same period. Data comprised modes and types of physical activity, age, and sex variables collected through the Exercise, Recreation and Sport Survey (ERASS), a series of independent cross-sectional Australia-wide surveys conducted yearly between 2001 and 2010. For each year, weighted population estimates were calculated for those participating in yoga/Pilates, t'ai chi/qigong, and fitness activities (e.g. aerobics, calisthenics). Linear regression and multiple logistic regression analyses were used to examine trends in prevalence rates over time and differences among sex and age (15-34; 35-54; 55+ years) groups, respectively. Average prevalence rates between 2001 and 2010 were 3.0% (95% CI 2.9-3.1) for yoga/Pilates, 0.6% (95% CI 0.5-0.6) for t'ai chi/qigong, and 19.2% (95% CI 18.9-19.4) for fitness activities. Across the decade, overall participation rates remained relatively stable for yoga/Pilates and t'ai chi/qigong, while increasing linearly for fitness activities. For both genders and in all three age groups, participation in fitness activities increased, whereas only in the 55+ age group was there a significant increase in yoga

    The physical and mental health of college-age youths tends to continuously decline around the world. It is therefore important to promote health during this period. As a traditional Chinese mind-body exercise, Tai Chi Chuan (TCC) may be an available selection. However for the college student population, the evidence is unclear as to whether TCC can be recommended as an effective exercise for promoting their physical and psychological wellbeing. Therefore high quality, rigorous, prospective, and well-controlled randomized trials are needed to further understand TCC serving as a psychological and physical intervention in college age populations. We designed a randomized, single-blind, parallel-controlled trial with a sample size of 206 participants. All the participants who meet the inclusion criteria come from Fujian University of Traditional Chinese Medicine (FJTCM). Participants of the TCC training group will receive TCC training at a frequency of five days per week for one hour per day for 12 weeks. No specific exercise will be administered on the participants in the control group. Both physical and mental health outcomes, including balance ability, lower limb proprioception, flexibility, physical fitness, self-efficacy, psychological symptoms, attention span, stress, self-esteem, mood and mindfulness, quality of life, and quality of sleep. Safety outcomes will be evaluated by blinded operators at baseline, 12 and 24-weeks post-intervention. This protocol presents an objective design of a randomized, single-blind trial that will test the effectiveness and safety of TCC on the physical and psychological wellbeing of college students. If the outcome is positive, the results will provide higher quality evidence of TCC on the physical and mental health of college age populations.

    Purpose. The aim of the study was to examine the effects of Tai Chi (TC) training on postural control when upright standing was perturbed by upper limb movement. Methods. Three groups, TC, Brisk walk (BW), and sedentary (SE), of thirty-six participants aged from 65 to 75 years were recruited from local community centers. Participants performed static balance task (quiet standing for 30 s with eyes open and closed) and fitting task (two different reaching distances X three different opening sizes to fit objects through). During tasks, the COP data was recorded while standing on the force plate. Criteria measures calculated from COP data were the maximum displacement in anterior-posterior (AP) and medial-lateral (ML) directions, the 95% confidence ellipse area (95% area), and the mean velocity. Results. No significant effect was observed in the static balance task. For fitting tasks, the group effect was observed in all directions on COP 95% area (p < 0.05) and the TC group showed reduced area. The tests of subject contrasts showed significant trends for reaching different distances and fitting different openings conditions in all directions, the 95% area, and the mean velocity (p < 0.05). Conclusion. Compared to the other two groups, long-term TC exercise helps in reducing the effects of upper body perturbation as measured by posture sway. PMID:28042306

    2008-01-01

    Tai Chi (TC) is the focus of a growing body of literature both qualitative and empirical. Yet there is a paucity of literature on teaching TC to either adolescents or children ages 10-13 presumably because of the level of attention and concentration TC requires. In the pediatric setting, TC appears best combined with other practice activities like mindfulness-based stress reduction (MBSR) that complement the practice of TC, sustain interest and synergistically enhance the benefits TC has been shown to produce in older populations. The literature on the effects of (MBSR) practices with children and teens are also limited. However, the corpus of TC studies suggests significant benefits could be transgenerational if presented in novel ways and taught in developmentally appropriate approaches to children. This chapter explores combining MBSR exercises with TC as one practice that can potentially accomplish this synergy. The chapter includes recommendations for a course design based on two projects created by the author integrating TC and MBSR for ages 11-14 in the inner city of Boston, Mass., USA.

    Tai Chi Chuan (TCC) is a traditional Chinese medicine practice and martial art with biopsychosocial aspects. This study aimed to examine the impact of participation in TCC on multiple domains of Quality of Life (QoL) and to assess the involvement of the psychological factors of self-efficacy, Locus of Control (LoC) and Hope in these effects. A total of 68 participants from the general community (13 males and 55 females) aged between 18 and 68 (M=43.55 years) and not currently suffering from a mental or physical illness took part in the study. It was found that TCC participants, as a group, scored significantly better than those in sedentary (book club) and active (gym exercise) control conditions on Psychological and Physical QoL, and that the Physical QoL benefits of TCC continue to accrue with years of practice. The three psychological factors were shown to variously mediate (self-efficacy) and moderate (internal LoC and Hope) this latter relationship. Whilst the results bear limitations (in particular small sample sizes), it is hoped that these findings will encourage further research into TCC, and consideration of TCC as part of the range of treatment options available in community-based mental and physical health management.

    Age-related cognitivee decline is a growing public health concern worldwide. More than a quarter of adults with cognitive impairment experience sleep disturbance. The objective of this pilot study was to evaluate the preliminary effects of tai chi qigong (TCQ) on improving the night-time sleep quality of older adults with cognitive impairment. Older adults with cognitive impairment who complain of sleep disturbance. A randomized controlled trial with two groups. Fifty-two subjects were recruited from two district elderly community centers and randomly assigned to either the TCQ group (n=27) or the control group (n=25). The intervention group received TCQ training consisting of two 60-minute sessions each week for 2 months. The control group was advised to maintain their usual activities. Sleep quality was measured by the Chinese Pittsburgh Sleep Quality Index. Quality of life was measured by Short-form 12, cognitive functions measured by mini-mental state examination, and subjective memory deficits measured by the memory inventory for Chinese. Data were collected at baseline, 2 months, and 6 months. Significant results were noted at 6 months in the Chinese Pittsburgh Sleep Quality Index global score (P=0.004), sleep duration (P=0.003), habitual sleep efficiency (P=0.002), and the Short-form 12 mental health component (P<0.001). The TCQ participants reported better sleep quality and a better (quality of life) mental health component than the control group. TCQ can be considered a useful nonpharmacological approach for improving sleep quality in older adults with cognitive impairment. CUHK_CCT00448 (https://www2.ccrb.cuhk.edu.hk/registry/public/287).

    Most cancer patients suffer from both the disease itself and symptoms induced by conventional treatment. Available literature on the clinical effects on cancer patients of acupuncture, Tuina, Tai Chi, Qigong, and Traditional Chinese Medicine Five-Element Music Therapy (TCM-FEMT) reports controversial results. The primary objective of this meta-analysis was to evaluate the effect of acupuncture, Tuina, Tai Chi, Qigong, and TCM-FEMT on various symptoms and quality of life (QOL) in patients with cancer; risk of bias for the selected trials also was assessed. Studies were identified by searching electronic databases (MEDLINE via both PubMed and Ovid, Cochrane Central, China National Knowledge Infrastructure, Chinese Scientific Journal Database, China Biology Medicine, and Wanfang Database). All randomized controlled trials (RCTs) using acupuncture, Tuina, Tai Chi, Qigong, or TCM-FEMT published before October 2, 2014, were selected, regardless of whether the article was published in Chinese or English. We identified 67 RCTs (5465 patients) that met our inclusion criteria to perform this meta-analysis. Analysis results showed that a significant combined effect was observed for QOL change in patients with terminal cancer in favor of acupuncture and Tuina (Cohen's d: 0.21-4.55, P effect on QOL of breast cancer survivors (P > 0.05). The meta-analysis also demonstrated that acupuncture produced small-to-large effects on adverse symptoms including pain, fatigue, sleep disturbance, and some gastrointestinal discomfort; however, no significant effect was found on the frequency of hot flashes (Cohen's d = -0.02; 95% CI = -1.49 to 1.45; P = 0.97; I(2) = 36%) and mood distress (P > 0.05). Tuina relieved gastrointestinal discomfort. TCM-FEMT lowered depression level. Tai Chi improved vital capacity of breast cancer patients. High risk of bias was present in 74.63% of the selected RCTs. Major sources of risk of bias were lack of blinding, allocation concealment, and incomplete

    Full Text Available Diminished control of standing balance, traditionally indicated by greater postural sway magnitude and speed, is associated with falls in older adults. Tai Chi (TC is a multisystem intervention that reduces fall risk, yet its impact on sway measures vary considerably. We hypothesized that TC improves the integrated function of multiple control systems influencing balance, quantifiable by the multi-scale "complexity" of postural sway fluctuations.To evaluate both traditional and complexity-based measures of sway to characterize the short- and potential long-term effects of TC training on postural control and the relationships between sway measures and physical function in healthy older adults.A cross-sectional comparison of standing postural sway in healthy TC-naïve and TC-expert (24.5±12 yrs experience adults. TC-naïve participants then completed a 6-month, two-arm, wait-list randomized clinical trial of TC training. Postural sway was assessed before and after the training during standing on a force-plate with eyes-open (EO and eyes-closed (EC. Anterior-posterior (AP and medio-lateral (ML sway speed, magnitude, and complexity (quantified by multiscale entropy were calculated. Single-legged standing time and Timed-Up-and-Go tests characterized physical function.At baseline, compared to TC-naïve adults (n = 60, age 64.5±7.5 yrs, TC-experts (n = 27, age 62.8±7.5 yrs exhibited greater complexity of sway in the AP EC (P = 0.023, ML EO (P<0.001, and ML EC (P<0.001 conditions. Traditional measures of sway speed and magnitude were not significantly lower among TC-experts. Intention-to-treat analyses indicated no significant effects of short-term TC training; however, increases in AP EC and ML EC complexity amongst those randomized to TC were positively correlated with practice hours (P = 0.044, P = 0.018. Long- and short-term TC training were positively associated with physical function.Multiscale entropy offers a complementary

    2012-01-01

    Full Text Available Abstract Background Tai Chi (TC is a mind-body exercise that shows potential as an effective and safe intervention for preventing fall-related fractures in the elderly. Few randomized trials have simultaneously evaluated TC's potential to reduce bone loss and improve fall-predictive balance parameters in osteopenic women. Methods In a pragmatic randomized trial, 86 post-menopausal osteopenic women, aged 45-70, were recruited from community clinics. Women were assigned to either nine months of TC training plus usual care (UC vs. UC alone. Primary outcomes were changes between baseline and nine months of bone mineral density (BMD of the proximal femur and lumbar spine (dual-energy X-ray absorptiometry and serum markers of bone resorption and formation. Secondary outcomes included quality of life. In a subsample (n = 16, quiet standing fall-predictive sway parameters and clinical balance tests were also assessed. Both intent-to-treat and per-protocol analyses were employed. Results For BMD, no intent-to-treat analyses were statistically significant; however, per protocol analyses (i.e., only including TC participants who completed ≥ 75% training requirements of femoral neck BMD changes were significantly different between TC and UC (+0.04 vs. -0.98%; P = 0.05. Changes in bone formation markers and physical domains of quality of life were also more favorable in per protocol TC vs. UC (P = 0.05. Changes in sway parameters were significantly improved by TC vs. UC (average sway velocity, P = 0.027; anterior-posterior sway range, P = 0.014. Clinical measures of balance and function showed non-significant trends in favor of TC. Conclusions TC training offered through existing community-based programs is a safe, feasible, and promising intervention for reducing multiple fracture risks. Our results affirm the value of a more definitive, longer-term trial of TC for osteopenic women, adequately powered to detect clinically relevant effects of TC on

    The incidence of strokes in industrialized nations is on the rise, particularly in the older population. In Canada, a minority of individuals who have had a stroke actually receive intensive rehabilitation because most stroke patients do not have access to services or because their motor recovery was judged adequate to return home. Thus, there is a considerable need to organize home-based rehabilitation services for everyone who has had a stroke. To meet this demand, telerehabilitation, particularly from a service center to the patient's home, is a promising alternative approach that can help improve access to rehabilitation services once patients are discharged home. This non-inferiority study will include patients who have returned home post-stroke without requiring intensive rehabilitation. To be included in the study, participants will: 1) not be referred to an Intensive Functional Rehabilitation Unit, 2) have a Rankin score of 2 or 3, and 3) have a balance problem (Berg Balance Scale score between 46 and 54). Participants will be randomly assigned to either the teletreatment group or the home visits group. Except for the delivery mode, the intervention will be the same for both groups, that is, a personalized Tai Chi-based exercise program conducted by a trained physiotherapist (45-minute session twice a week for eight consecutive weeks). The main objective of this research is to test the non-inferiority of a Tai Chi-based exercise program provided via telerehabilitation compared to the same program provided in person at home in terms of effectiveness for retraining balance in individuals who have had a stroke but do not require intensive functional rehabilitation. The main outcome of this study is balance and mobility measured with the Community Balance and Mobility Scale. Secondary outcomes include physical and psychological capacities related to balance and mobility, participants' quality of life, satisfaction with services received, and cost

    Tai Li Chi engaged in the study of amalgam magnetism with his mentor, the famous physicist L.F. Bates when he studied in University of London in 1934. Tai Li Chi and L.F. Bates measured the magnetic susceptibility of the known components of bismuth, chromium, copper, and manganese amalgam using the Gouy method. They found that, in addition to copper, metals that were diamagnetic in the solid state exhibited paramagnetism in the amalgam state;the susceptibility of manganese-amalgam showed temperature hysteresis. In addition, they studied the titration method in magnetic susceptibility measurements. A review and analysis of the experimental research of Tai Li Chi is presented based on his dissertation, files and papers in the 1930s, which may help us to understand the status of this field in China and also know Tai's studies in UK ac-cording to the new historical data.%戴礼智于1934年留学英国伦敦大学,师从著名磁学家贝茨从事汞合金磁性研究。戴礼智与导师合作,运用古埃(Gouy)法对已知成分的铋、铬、铜、锰等汞合金的磁化率进行测量,发现除铜外,在固态下显示抗磁性的金属,其汞合金均显示顺磁性;发现锰-汞合金的磁化率具有温度滞后现象;此外,还研究了滴定法磁化率测量。文章以戴礼智的博士论文、档案及发表论文为基础,回顾并分析了上世纪30年代戴礼智在汞合金磁性方面的实验研究工作,以了解当时中国物理学界在此方面的贡献。新的史料也提供了戴礼智在英国留学的情形。

    in $K$-user single-input single-output (SISO) frequency selective fading interference channels, it is shown that the achievable multiplexing gain is almost surely $K/2$ by using interference alignment (IA). However when the signaling dimensions is limited, allocating all the resource to all the users simultaneously is not optimal. According to this problem, a group based interference alignment (GIA) scheme is proposed and a search algorithm is designed to get the group patterns and the resource allocation among them. Analysis results show that our proposed scheme achieves a higher multiplexing gain when the resource is limited.

    This cross-sectional exploratory study aimed to compare the one-leg-stance time and the six-minute walk distance among TC Qigong-trained NPC survivors, untrained NPC survivors, and healthy individuals. Twenty-five survivors of NPC with TC Qigong experience, 27 survivors of NPC without TC Qigong experience, and 68 healthy individuals formed the NPC-TC Qigong group, NPC-control group, and healthy-control group, respectively. The one-leg-stance (OLS) timed test was conducted to assess the single-leg standing balance performance of the participants in four conditions: (1) standing on a stable surface with eyes open, (2) standing on a compliant surface with eyes open, (3) standing on a stable surface with eyes closed, and (4) standing on a compliant surface with eyes closed. The six-minute walk test (6MWT) was used to determine the functional balance performance of the participants. Results showed that the NPC-control group had a shorter OLS time in all of the visual and supporting surface conditions than the healthy control group (P Qigong-NPC group was comparable to that of the healthy control group in the somatosensory-challenging condition (condition 3) (P = 0.168) only. Additionally, there was no significant difference in the 6MWT distance among the three groups (P > 0.05). TC Qigong may be a rehabilitation exercise that improves somatosensory function and OLS balance performance among survivors of NPC.

  10. Precise Point Positioning for TAI Computation

    Directory of Open Access Journals (Sweden)

    Gérard Petit

    2008-01-01

    Full Text Available We discuss the use of some new time transfer techniques for computing TAI time links. Precise point positioning (PPP uses GPS dual frequency carrier phase and code measurements to compute the link between a local clock and a reference time scale with the precision of the carrier phase and the accuracy of the code. The time link between any two stations can then be computed by a simple difference. We show that this technique is well adapted and has better short-term stability than other techniques used in TAI. We present a method of combining PPP and two-way time transfer that takes advantage of the qualities of each technique, and shows that it would bring significant improvement to TAI links.

    At 17:47 UT on 20 September 1999, a large earthquake of magnitude Mw 7.6 struck the central Taiwan near a small town of Chi-Chi. The ground-based receivers of the global positioning system (GPS) in the Taiwan area detected coseismic ionospheric disturbances (CIDs) in the total electron content (TEC) triggered by the Chi-Chi earthquake. When the CIDs travel away from the origin on the Earth surface and then propagate into the ionosphere, their amplitudes and periods generally become smaller and longer, respectively. Moreover, two global grid searches, adapting the ray-tracing and the beam-forming techniques, have been used to analyze the observed GPS TEC. We have not only estimated the average speed of the CIDs propagating in the atmosphere and ionosphere but also determined the location of CID origin on the Earth surface by using the two techniques. The results show that the observed CIDs result from shock-acoustic waves triggered by sudden and large vertical motions of the Chi-Chi earthquake.

    Falls are associated with morbidity, loss of independence, and mortality. While land-based group exercise and Tai Chi programs reduce the risk of falls, aquatic therapy may allow patients to complete balance exercises with less pain and fear of falling; however, limited data exist. The objective of the study was to pilot the implementation of an aquatic group based on Ai Chi principles (Aquabalance) and to evaluate the safety, intervention acceptability, and intervention effect sizes. Pilot observational cohort study. Forty-two outpatients underwent a single 45-minute weekly group aquatic Ai Chi-based session for eight weeks (Aquabalance). Safety was monitored using organizational reporting systems. Patient attendance, satisfaction, and self-reported falls were also recorded. Balance measures included the Timed Up and Go (TUG) test, the Four Square Step Test (FSST), and the unilateral Step Tests. Forty-two patients completed the program. It was feasible to deliver Aquabalance, as evidenced by the median (IQR) attendance rate of 8.0 (7.8, 8.0) out of 8. No adverse events occurred and participants reported high satisfaction levels. Improvements were noted on the TUG, 10-meter walk test, the Functional Reach Test, the FSST, and the unilateral step tests (p < 0.05). The proportion of patients defined as high falls risk reduced from 38% to 21%. The study was limited by its small sample size, single-center nature, and the absence of a control group. Aquabalance was safe, well-attended, and acceptable to participants. A randomized controlled assessor-blinded trial is required.

    Jackson, Robert H.; Freund, Henry P.; Pershing, Dean E.; Taccetti, J. M.

    1993-11-01

    A magnetic wiggler design has been developed for applications in free-electron lasers which is scalable to small periods with high field amplitude, high beam current acceptance, and excellent transverse focusing and beam propagation properties. The Coaxial Hybrid Iron (CHI) wiggler design consists of a coaxial arrangement of alternating ferromagnetic and non- ferromagnetic rings with the central portion of the coax shifted by one half period. The entire arrangement is immersed in a solenoidal field which results in a cylindrically symmetric periodic field. A key advantage of this wiggler configuration is its capacity to handle very high beam currents with excellent focusing and transport properties. FEL configuration using the CHI wiggler design have the potential for high power, high frequency coherent generation in relatively compact systems. Analytic and simulated characteristics of the CHI wiggler are presented.

  19. CHY formula and MHV amplitudes

    CERN Document Server

    Du, Yi-jian; Wu, Yong-shi

    2016-01-01

    In this paper, we study the relation between the Cachazo-He-Yuan (CHY) formula and the maximal-helicity-violating (MHV) amplitudes of Yang-Mills and gravity in four dimensions. We prove that only one special rational solution of the scattering equations found by Weinzierl support the MHV amplitudes. Namely, localized at this solution, the integrated CHY formula reproduces the Parke-Taylor formula for Yang-Mills amplitudes as well as the Hodges formula for gravitational amplitudes. This is achieved by developing techniques, in a manifestly M\\"obius covariant formalism, to explicitly compute relevant reduced Pfaffians/determinants. We observe and prove two interesting properties (or identities), which facilitate the computations. We also check that all the other $(n-3)!-1$ solutions to the scattering equations do not support the MHV amplitudes, and prove analytically that this is indeed true for the other special rational solution proposed by Weinzierl, that actually supports the anti-MHV amplitudes.

  20. Phylogenetic invariants for group-based models

    CERN Document Server

    Donten-Bury, Maria

    2010-01-01

    In this paper we investigate properties of algebraic varieties representing group-based phylogenetic models. We give the (first) example of a nonnormal general group-based model for an abelian group. Following Kaie Kubjas we also determine some invariants of group-based models showing that the associated varieties do not have to be deformation equivalent. We propose a method of generating many phylogenetic invariants and in particular we show that our approach gives the whole ideal of the claw tree for 3-Kimura model under the assumption of the conjecture of Sturmfels and Sullivant. This, combined with the results of Sturmfels and Sullivant, would enable to determine all phylogenetic invariants for any tree for 3-Kimura model and possibly for other group-based models.

    In this paper, we develop a rather general way to reduce integrands with polarisation involved in the Cachazo-He-Yuan formulae, such as the reduced Pfaffian and its compactification, as well as the new object for F3 amplitude. We prove that the reduced Pfaffian vanishes unless on a certain set of solutions. It leads us to build up the 4d CHY formulae using spinors, which strains off many useless solutions. The supersymmetrization is straightforward and may provide a hint to understanding ambitwistor string in 4d.

    Full Text Available Background. Stroke is a major healthcare problem with serious long-term disability and is one of the leading causes of death in the world. Prevention of stroke is considered an important strategy. Methods. Seven electronic databases were searched. Results. 36 eligible studies with a total of 2393 participants were identified. Primary outcome measures, TCC exercise combined with other intervention had a significant effect on decreasing the incidence of nonfatal stroke (n=185, RR = 0.11, 95% CI 0.01 to 0.85, P=0.03 and CCD (n=125, RR = 0.33, 95% CI 0.11 to 0.96, P=0.04. For the risk factors of stroke, pooled analysis demonstrated that TCC exercise was associated with lower body weight, BMI, FBG level, and decreasing SBP, DBP, plasma TC, and LDL-C level regardless of the intervention period less than half a year or more than one year and significantly raised HDL-C level in comparison to nonintervention. Compared with other treatments, TCC intervention on the basis of the same other treatments in patients with chronic disease also showed the beneficial effect on lowering blood pressure. Conclusion. The present systematic review indicates that TCC exercise is beneficially associated with the primary prevention of stroke in middle-aged and elderly adults by inversing the high risk factors of stroke.

    Full Text Available Falls in older adults are a significant public health issue and a particularly significant health risk in Minnesota. With accumulating research evidence suggesting that falls can be prevented through exercise, there is an increased public health effort among organizations serving older adults to translate and disseminate evidence-based programs into the community. Such efforts, however, face additional challenges if they are implemented in communities with older adults from different cultural backgrounds and languages. This paper briefly describes a pilot community-based dissemination project, including the initiation, implementation, process, and outcomes, of an evidence-based fall prevention (Tai Ji Quan: Moving for Better Balance formerly known as Tai Chi: Moving for Better Balance through a local Area Agency on Aging in the Minneapolis/St. Paul metropolitan area in Minnesota (USA. Overall, the program was successfully implemented resulting in adoption by local community organizations serving Asian and, to a lesser degree, East African non-English speaking older adults. Bilingual community instructors were trained to lead the classes resulting in broad participation and improved physical performance by the older adults targeted for the intervention. The results from this pilot study indicate that Tai Ji Quan: Moving for Better Balance can be implemented with positive results in non-English speaking community settings using bilingual leaders.

    Full Text Available Tai Ji Quan, developed as a martial art, has traditionally served multiple purposes, including self-defense, competition/performance, and health promotion. With respect to health, the benefits historically and anecdotally associated with Tai Ji Quan are now being supported by scientific and clinical research, with mounting evidence indicating its potential value in preventing and managing various diseases and improving well-being and quality of life in middle-aged and older adults. The research findings produced to date have both public health significance and clinical relevance. However, because of its roots in the martial arts, transforming traditional Tai Ji Quan movements and training approaches into contemporary therapeutic programs and functional applications is needed to maximize its ultimate utility. This paper addresses this issue by introducing Tai Ji Quan: Moving for Better Balance, a functional therapy that involves the use of Tai Ji Quan principles and Yang-style-based movements to form an innovative, contemporary therapeutic approach that integrates motor, sensory, and cognitive components to improve postural control, gait, and mobility for older adults and those who have neurodegenerative movement impairments. It provides a synergy of traditional and contemporary Tai Ji Quan practice with the ultimate goal of improving balance and gait, enhancing performance of daily functional tasks, and reducing incidence of falls among older adults.

  9. RecBCD Enzyme "Chi Recognition" Mutants Recognize Chi Recombination Hotspots in the Right DNA Context.

    Amundsen, Susan K; Sharp, Jake W; Smith, Gerald R

    2016-09-01

    RecBCD enzyme is a complex, three-subunit protein machine essential for the major pathway of DNA double-strand break repair and homologous recombination in Escherichia coli Upon encountering a Chi recombination-hotspot during DNA unwinding, RecBCD nicks DNA to produce a single-stranded DNA end onto which it loads RecA protein. Conformational changes that regulate RecBCD's helicase and nuclease activities are induced upon its interaction with Chi, defined historically as 5' GCTGGTGG 3'. Chi is thought to be recognized as single-stranded DNA passing through a tunnel in RecC. To define the Chi recognition-domain in RecC and thus the mechanism of the RecBCD-Chi interaction, we altered by random mutagenesis eight RecC amino acids lining the tunnel. We screened for loss of Chi activity with Chi at one site in bacteriophage λ. The 25 recC mutants analyzed thoroughly had undetectable or strongly reduced Chi-hotspot activity with previously reported Chi sites. Remarkably, most of these mutants had readily detectable, and some nearly wild-type, activity with Chi at newly generated Chi sites. Like wild-type RecBCD, these mutants had Chi activity that responded dramatically (up to fivefold, equivalent to Chi's hotspot activity) to nucleotide changes flanking 5' GCTGGTGG 3'. Thus, these and previously published RecC mutants thought to be Chi-recognition mutants are actually Chi context-dependence mutants. Our results fundamentally alter the view that Chi is a simple 8-bp sequence recognized by the RecC tunnel. We propose that Chi hotspots have dual nucleotide sequence interactions, with both the RecC tunnel and the RecB nuclease domain.

    Energy Technology Data Exchange (ETDEWEB)

    Goldsmith, S.Y.; Phillips, L.R.; Spires, S.V.

    1998-12-17

    We have completed and exercised a communication framework called CHI (CLOS to HTML Interface) by which agents can communicate with humans. CHI follows HTTP (HyperText Transfer Protocol) and produces HTML (HyperText Markup Language) for use by WWW (World-Wide Web) browsers. CHI enables the rapid and dynamic construction of interface mechanisms. The essence of CHI is automatic registration of dynamically generated interface elements to named objects in the agent's internal environment. The agent can access information in these objects at will. State is preserved, so an agent can pursue branching interaction sequences, activate failure recovery behaviors, and otherwise act opportunistically to maintain a conversation. The CHI mechanism remains transparent in multi-agent, multi-user environments because of automatically generated unique identifiers built into the CHI mechanism. In this paper we discuss design, language, implementation, and extension issues, and, by way of illustration, examine the use of the general CHI/HCHI mechanism in a specific international electronic commerce system. We conclude that the CHI mechanism is an effective, efficient, and extensible means of the agent/human communication.

    Full Text Available The relationship between physical activity (PA and cognition has received much attention recently. While evidence of improved cognition following PA has consistently been observed, the majority of studies have spotlighted aerobic exercise and the effects of other modes of PA, such as Tai Ji Quan, on cognition have received limited attention. This article provides a brief review of the literature concerning the influence of Tai Ji Quan on cognition in older adults, including those with intact cognition and those with cognitive impairment. In addition, this review proposes potential mechanisms (cardiovascular fitness, motor fitness, movement coordination, social interaction, and meditation statuses as well brain structure and function evaluated from a neuroimaging perspective that may explain the Tai Ji Quan–cognition relationship. Finally, we present suggestions for future research. In conclusion, Tai Ji Quan, with its multi-faceted characteristics, shows promise as a mode of PA for enhancing cognition, as well as brain health, in older adults. Based on the findings in this review, further exploration of the effects of Tai Ji Quan on cognition in older adults is warranted.

    Trait affect scales have been a mainstay of the assessment literature for more than 50 years. These scales have demonstrated impressive construct validity, including substantial relations with personality, satisfaction, and psychopathology. However, the accumulating evidence has exposed several limitations, including (a) problems associated with retrospective biases, (b) lower temporal stability because of enhanced susceptibility to transient error, and (c) reduced self-other agreement. These limitations motivated the creation of the Temperament and Affectivity Inventory (TAI), which uses a traditional personality format (i.e., full sentences rather than single words or short phrases). The 12 TAI scales were created based on factor analyses in two samples and validated in four additional samples. The scales are internally consistent, highly stable over time, and show strong convergent, discriminant, and incremental validity in relation to self-report and interview-based measures of personality and psychopathology. Thus, the TAI provides a promising new approach to assessing trait affectivity.

Broadband Ultrsonic Attenuation (BUA) and velocity of sound (VOS), bone formation marker Osteocalcin (OSTN) and bone resorption markers urinary Pyridum crosslinks (PYR and D-PYR) were studied before and after four months of Tai Ji exercise. Improved bone structure and increased bone density in menopausal women were reflected by BUA results. The increased BUA appears to be associated with increased bone formation rather than decreased bone resorption.

    To examine the effects of long-term Tai Ji Quan (Chinnese Traditional Exercise) on automatic nervous modulation in the elders. The 18 subjects from Tai Ji Quan exercise class in Liaoning University of Retired Veteran Cadres were assigned into long-term Tai Ji Quan exercise group including 10 subjects and novice group including 8 subjects. Electrocardiography, respiratory and blood pressure data were collected on the following time points: at rest before Tai Ji Qhuan exercise and 30 min or 60 min after Tai Ji Quan exercise. The subjects at rest state in the long-term Tai Ji Quan exercise group showed higher than the subjects in the novice group in resperitory rate (RR), standard deviations of normal to normal intervals (SDNN), total power (TP), low frequency power (LFP), high frequency power (HFP), normalized high frequency power (nHFP), but lower in LFP/HFP, systolic and diastolic blood pressure, and heart rate. At rest state the respiratory rate of subjects in long-term Tai Ji Quan exercise group was significantly lower than the novices. After Tai Ji Quan exercise, TP, nHFP, LFP/HFP, heart rate and systolic pressure showed significantly changes, and the change level of Tai Ji Quan on these indices was larger in Tai Ji Quan exercise group than that in the novice group. Long-term Tai Ji Quan exercise can improve vagal modulations, and tend to reduce the sympathetic modulations.

    Ambient conditions have the potential to cause changes in liquid scintillator detector gain that vary with time and temperature. These gain shifts can lead to poor resolution in both energy as well as pulse shape discrimination. In order to correct for these shifts in the Chi-Nu high energy array, a laser system has been developed for calibration of the pulse height signals.

  7. Effect of near-fault earthquake on bridges: lessons learned from Chi-Chi earthquake

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    The objective of this paper is to describe the lessons learned and actions that have been taken related to the seismicdesign of bridge structures after the Chi-Chi, Taiwan earthquake. Much variable near-fault ground motion data was collected fromthe rupture of Chelungpu fault during the Chi-Chi earthquake, allowing the seismic response of bridge structures subjected to thesenear-fault ground motions to be carefully examined. To study the near-fault ground motion effect on bridge seismic design codes, atwo-level seismic design of bridge structures was developed and implemented. This design code reflects the near-fault factors in theseismic design forces. Finally, a risk assessment methodology, based on bridge vulnerability, is also developed to assist in decisionsfor reducing seismic risk due to failure of bridges.

    Full Text Available ULF emission data at Lunping (epicentral distance, 120 km have been analysed for the Chi-Chi earthquake (with magnitude 7.6 and depth of 11 km in Taiwan which occurred on 21 September 1999. Simple intensity analyses have not yielded any significant results but we have found, based on the analysis of polarization (the ratio of vertical magnetic field component Z to the horizontal component G, that the polarization (Z/G showed a significant enhancement for two months before the earthquake. This kind of temporal evolution of polarization seems to be very similar to previous results, so that it is highly likely that this phenomenon may be associated with the Chi-Chi earthquake. Also, the comparison of the results of polarization analyses, by changing the signal threshold, has given us an approximate intensity of the seismogenic emission of the order of the monthly mean value.

We present numerical results appropriate for the Fermilab Tevatron.

    Cardona, Carlos; Gomez, Humberto

    2016-10-01

    Recently, we proposed a new approach using a punctured Elliptic curve in the CHY framework in order to compute one-loop scattering amplitudes. In this note, we further develop this approach by introducing a set of connectors, which become the main ingredient to build integrands on {M}_{1,n} , the moduli space of n-punctured Elliptic curves. As a particular application, we study the Φ3 bi-adjoint scalar theory. We propose a set of rules to construct integrands on {M}_{1,n} from Φ3 integrands on {M}_{0,n} , the moduli space of n-punctured spheres. We illustrate these rules by computing a variety of Φ3 one-loop Feynman diagrams. Conversely, we also provide another set of rules to compute the corresponding CHY-integrand on {M}_{1,n} by starting instead from a given Φ3 one-loop Feynman diagram. In addition, our results can easily be extended to higher loops.

  11. Barbed congruence of the asymmetric chi calculus

    Institute of Scientific and Technical Information of China (English)

    DONG Xiao-ju; FU Yu-xi

    2006-01-01

    The chi calculus is a model of mobile processes. It has evolved from the pi-calculus with motivations from simplification and communication-as-cut-elimination. This paper studies the chi calculus in the framework incorporating asymmetric communication. The major feature of the calculus is the identification of two actions:x/x and τ. The investigation on the barbed bisimilarity shows how the property affects the observational theory.Based on the definition of the barbed bisimilarity, the simulation properties of the barbed bisimilarity are studied. It shows that the algebraic properties of the barbed bisimilarity have changed greatly compared with the chi calculus. Although the definition of the barbed bisimilarity is very simple, the property of closeness under contexts makes it difficult to understand the barbed bisimilarity directly. Therefore an open style definition of the barbed bisimilarity is given, which is a context free description of barbed bisimilarity. Its definition is complex,but it is a well-behaved relation for it coincides with the barbed bisimilarity. It also helps to build an axiomatization system for the barbed congruence. Besides the axioms for the strong barbed bisimilarity, the paper proposes a new tau law and four new update laws for the barbed congruence. Both the operational and algebraic properties of the enriched calculus improve the understanding of the bisimulation behaviors of the model.

    A complementary strategy of utilizing ππ* excited state of alkene instead of nπ* excited state of the carbonyl chromophore in a "transposed Paternò-Büchi" reaction is evaluated with atropisomeric enamides as the model system. Based on photophysical investigations, the nature of excited states and the reactive pathway was deciphered leading to atropselective reaction. This new concept of switching of excited-state configuration should pave the way to control the stereochemical course of photoreaction due to the orbital approaches required for photochemical reactivity.

    Using a sample of 9.7 million B meson pairs collected with the CLEO detector, we study B decays to the chi_c1 and chi_c2 charmonia states, which are reconstructed via their radiative decays to J/psi. We first measure the branching fraction for inclusive chi_c1 production in B decays to be Br(B->chi_c1 X)=(4.14+-0.31+-0.40)*10^-3, where the first uncertainty is statistical and the second one is systematic. We derive the branching fractions for direct chi_c1 and chi_c2 production in B decays by subtracting the known contribution of the decay chain B->psi(2S)X with psi(2S)->chi_c1,2 gamma. We obtain Br[B->chi_c1(direct) X]=(3.83+-0.31+-0.40)*10^-3. No statistically significant signal for chi_c2 production is observed in either case. Using the Feldman-Cousins approach, we determine the 95% confidence intervals to be [0.2, 2.0]*10^-3 for Br(B->chi_c2 X), [0.0,1.7]*10^-3 for Br[B->chi_c2(direct) X], and [0.00,0.44] for the ratio Br[B->chi_c2(direct) X]/Br[B->chi_c1(direct) X].

We illustrate these rules by computing a variety of $\\Phi^3$ one-loop Feynman diagrams. Conversely, we also provide another set of rules to compute the corresponding CHY-integrand on $\\mathfrak{M}_{1,n}$ by starting instead from a given $\\Phi^ 3$ one-loop Feynman diagram. In addition, our results can easily be extended to higher loops.

    Recently, we proposed a new approach using a punctured Elliptic curve in the CHY framework in order to compute one-loop scattering amplitudes. In this note, we further develop this approach by introducing a set of connectors, which become the main ingredient to build integrands on M{sub 1,n}, the moduli space of n-punctured Elliptic curves. As a particular application, we study the Φ{sup 3} bi-adjoint scalar theory. We propose a set of rules to construct integrands on M{sub 1,n} from Φ{sup 3} integrands on M{sub 0,n}, the moduli space of n-punctured spheres. We illustrate these rules by computing a variety of Φ{sup 3} one-loop Feynman diagrams. Conversely, we also provide another set of rules to compute the corresponding CHY-integrand on M{sub 1,n} by starting instead from a given Φ{sup 3} one-loop Feynman diagram.

  2. 3-D Numerical Investigation of the Tsaoling Landslide Induced by Chi-Chi Earthquake, Taiwan.

    2004-12-01

    Large landslides occurred in the mountainous area near the epicenter of the Sept. 21st, 1999, Chi-Chi earthquake in central Taiwan. These landslides were triggered by the Mw = 7.6 earthquake, which resulted in more than 2,400 human casualties and widespread damage. The 1999 Chi-Chi earthquake triggered a catastrophic Tsaloing landslide, which mobilized about 0.125 km3 of rock and soil that slid across the Chingshui River and created a 5 km long natural dam. One fifth of the landslide mass dropped into the Chingshui River, the rest jumped over the river. At least five large landslides occurred in Tsaoling area are induced by big earthquake and heavy rainfalls since 1862 to 1999. Geological investigation shows that the prevailing attitude of sedimentary formation is about N45W with a dipping angle of 12S. First we used Remark Method to calculate the stability of slope. The bottom of slope has been eroded by Chingshui stream, and the PGA (Peak Ground Acceleration) in Chi-Chi earthquake was exceeded the yield acceleration along the sliding surface. The landslide mechanism may be including flowing, rolling, bouncing and sliding. The rock on the fault plane during faulting can generate pseudotachylyte resulted from melted rock by frictional heat energy along the sliding surface. The frictional melted rocks were found out in the Chiu-Fen-Erh-Shan collapses. However, we didn¡¦t found out the frictional melted rock in Tsaoling area. If we calculated the kinetic energy which was converted to heat energy, the increase of temperature was enough to melt the rocks on sliding surface. When the rocks on the sliding surface had been melted, the friction on the sliding surface must be decrease. Therefore, the 0.125 km3 debris had sufficient kinetic energy to across Chingshui River to the other side of the river. Using 3D distinct-element modeling (PFC3d code), we try to simulate kinematic process of Tsaoling landslide. Our numerical model was compose of about 10,000 spherical

    In this study, the authors attempted to determine factors associated with earthquake deaths in the great Chi-Chi Earthquake that occurred on September 21, 1999, in Taiwan. An isoseismal map was used to identify life-threatening hazards. The vertical peak ground acceleration of ground motion intensity was deemed the most appropriate index for the evaluation of building collapse and mortality. Mortality increased with the increase in earthquake intensity, and building collapse, approaching the epicenter. The greatest number of collapsed buildings and human deaths occurred between the Chelungpu Fault and the Shuantun Fault. Individuals 65 yr of age and older were the most vulnerable to the impact. The authors' findings suggest that improvements in earthquake-resistant building design and construction, as well as improved medical rescue for the elderly, could reduce the level of exposure to earthquake hazards.

    Co-seismic deformation due to the 1999 Chi-Chi earthquake, Mw=7.6, was measured from SPOT satellite images in combination to available co-seismic GPS data. Surface ruptures clearly show off in the measured horizontal displacement field allowing for a detailed cartography and measurement of co-seismic slip along the fault trace. The strike-perpendicular component varies smoothly and indicates 4-5 m thrust on average. The strike-parallel component of about 3-4 m to the south, near the epicenter, gradually increases northward to reach about 7-8 m. This pattern is associated with a general clockwise deviation of surface displacements to the north. Displacements and strain are much larger in the hanging wall than in the footwall. The zone of large co-seismic surface displacement fall within the Sun Moon Lake seismic gap and is bounded to the east by the range front where intense micro-seismic activity was taking place before the earthquake. Co-seismic deformation was modelled using elastic dislocations. The fault geometry was constrained from structural geology. Its geometry and the slip distribution were adjusted to fit both horizontal surface displacements measured from SPOT and vertical displacements measured from GPS. The fault plane makes shallow 20-35o east dipping ramp and roots into a décollement at a depth of 6 to 8 km. The data are satisfactorily adjusted, assuming a nearly constant slip azimuth on the main fault plane close to the azimuth of plate convergence (N305oE +/-5o) and with most of the co-seismic slip being confined (near the surface) on the shallow ramp. The northward rotation of displacements are well reproduced from the model and thus appear to be an edge effect due to oblique direction of thrusting and to the eastward bend of the fault trace at its northern end. Based on these data, we suggest that the model proposed for the Himalaya of Nepal also apply to some extent to the central range of Taiwan. In the inter-seismic period, aseismic shear

    In this article we perform a second order perturbation analysis of the gravitational metric theory of gravity $ f(\\chi) = \\chi^{3/2} $ developed by Bernal et al. (2011). We show that the theory is capable to account exactly for two observational facts: (1) the phenomenology of flattened rotation curves through the Tully-Fisher relation observed in spiral galaxies, and (2) the details of observations of gravitational lensing in galaxies and groups of galaxies, without the need of any dark matter. We show how all dynamical observations on flat rotation curves and gravitational lensing can be synthesised in terms of the empirically required metric coefficients of any metric theory of gravity. We construct the corresponding metric components for the theory presented at second order in perturbation, which are shown to be perfectly compatible with the empirically derived ones. It is also shown that, in order to obtain a complete full agreement with the observational results, a specific signature of Riemann's tensor...

  7. Observations of changes in waveform character induced by the 1999 M w7.6 Chi-Chi earthquake

    We observe changes in the waveforms of repeating earthquakes in eastern Taiwan following the 1999 Mw7.6 Chi-Chi earthquake, while their recurrence intervals appear to be unaffected. There is a clear reduction in waveform similarity and velocity changes indicated by delayed phases at the time of the Chi-Chi event. These changes are limited to stations in and paths that cross the 70 ?? 100 km region surrounding the Chi-Chi source area, the area where seismic intensity and co-seismic surface displacements were largest. This suggests that damage at the near-surface is responsible for the observed waveform changes. Delays are largest in the late S-wave coda, reaching approximately 120 ms. This corresponds to a path averaged S wave velocity reduction of approximately 1%. There is also evidence that damage in the fault-zone caused changes in waveform character at sites in the footwall, where source-receiver paths propagate either along or across the rupture. The reduction in waveform similarity persists through the most recent repeating event in our study (November 15, 2007), indicating that the subsurface damage induced by the Chi-Chi earthquake did not fully heal within the first 8 years following the Chi-Chi earthquake. ?? 2011 by the American Geophysical Union.

    Overcoming the conflicts between protecting water resource heritage features and the sustainable development of modern society is a major undertaking. Lougangs (rivulets) and polders are Lake-Tai-Basin-specific water resource engineering projects that hold a significant historic position. This paper presents background on water resource heritage features, based on the origins and evolution of Lougangs along Lake Tai. Through analysis of their value and current standing, we propose countermeasures for protection and development of the Lougang water resource heritage features along Lake Tai.

    Falls are the main cause of accidental death in the elderly people, which is associated with balance control ability and flexibility of the older adults. The purpose of this study was to evaluate the effect of TCC on the balance control and flexibility of the older adults. We searched the PubMed, Embase and Cochrane library with the deadline of May 15th, 2014. This meta-analysis was performed using RevMan5.0 software. The overall weighted mean difference (WMD) and its 95% confidence interval (CI) were calculated. A total of 7 randomized controlled trials including 1088 participants (544 TCC practitioners and 544 participants with other interventions) were considered in this meta-analysis. The pooled estimate of Get up and Go test (WMD=1.04; 95%CI: 0.67-1.41; Pbalance) test (WMD=2.86; 95%CI: 1.91-3.81; Pbalance control ability of older adults. In conclusion, TCC practice was beneficial to improve the balance control ability and flexibility of older adults, which may be the reason of preventing falls. Copyright © 2014 Elsevier Ireland Ltd.

    Using a sample of 3 x 10^6 psi(2S) decays collected by the CLEO III and CLEO_c detector configurations, we present results of a study of \\chi_{c0} and \\chi_{c2} decays into eta-eta, eta-etaprime, and etaprime-etaprime final states. We find B(chi_{c0} -> eta-eta)= (0.31+-0.05+-0.04+-0.02)%, B(chi_{c0} -> eta-etaprime) etaprime-etaprime) = (0.17 +- 0.04 +-0.02 +-0.01)%. We also present upper limits for the decays of \\chi_{c2} into these final states. These results give information on the decay mechanism of \\chi_c states into pseudoscalars.

  5. Where are $\\chi_{cJ}(3P)$?

    CERN Document Server

    Chen, Dian-Yong

    2016-01-01

    In the present work, we propose the $Y(4140)$ as the $\\chi_{c1}(3P)$ state by studying the $\\chi_{c1} \\pi^+ \\pi^-$ invariant mass spectrum of the $B\\to K \\chi_{c1} \\pi^+ \\pi^-$ process. In the $D\\bar{D}$ invariant mass spectrum of the $B\\to K D\\bar{D}$ process, we find a new resonance with the mass and width to be $ (4083.0 \\pm 5.0) $ and $ (24.1 \\pm 15.4) $ MeV, respectively, which could be a good candidate of the $\\chi_{c0}(3P)$ state. The theoretical investigations on the decay behaviors of the $\\chi_{cJ}(3P)$ in the present work support the assignments of the $Y(4140)$ and $Y(4080)$ as the $\\chi_{c1}(3P)$ and $\\chi_{c0}(3P)$ states, respectively. In addition, the $\\chi_{c2}(3P)$ state is predicted to be a very narrow state. The results in the present work could be tested by further experiments in the LHCb and forthcoming Belle II.

  6. Model Waveform Accuracy Requirements for the $\\chi^2$ Discriminator

    CERN Document Server

    Lindblom, Lee

    2016-01-01

    This paper derives accuracy standards for model gravitational waveforms required to ensure proper use of the $\\chi^2$ discriminator test in gravitational wave (GW) data analysis. These standards are different from previously established requirements for detection and waveform parameter measurement based on signal-to-noise optimization. We present convenient formulae both for evaluating and interpreting the contribution of model errors to measured $\\chi^2$ values. Motivated by these formula, we also present an enhanced, complexified variant of the standard $\\chi^2$ statistic used in GW searches. While our results are not directly relevant to current searches (which use the $\\chi^2$ test only to veto signal candidates with extremely high $\\chi^2$ values), they could be useful in future GW searches and as figures of merit for model gravitational waveforms.

  7. When are emotions related to group-based appraisals? A comparison between group-based emotions and general group emotions.

    Science.gov (United States)

    Kuppens, Toon; Yzerbyt, Vincent Y

    2014-12-01

    In the literature on emotions in intergroup relations, it is not always clear how exactly emotions are group-related. Here, we distinguish between emotions that involve appraisals of immediate group concerns (i.e., group-based emotions) and emotions that do not. Recently, general group emotions, measured by asking people how they feel "as a group member" but without specifying an object for these emotions, have been conceptualized as reflecting appraisals of group concerns. In contrast, we propose that general group emotions are best seen as emotions about belonging to a group. In two studies, general group emotions were closely related to emotions that are explicitly measured as belonging emotions. Two further studies showed that general group emotions were not related to appraisals of immediate group concerns, whereas group-based emotions were. We argue for more specificity regarding the group-level aspects of emotion that are tapped by emotion measures.

  8. Dynamic rupture process of the 1999 Chi-Chi,Taiwan, earthquake

    Haiming Zhang; Xiaofei Chen

    2009-01-01

    In this study, we preliminarily investigated the dynamic rupture process of the 1999 Chi-Chi, Taiwan, earthquake by using an extended boundary integral equation method, in which the effect of ground surface can be exactly included. Parameters for numerical modeling were carefully assigned based on previous studies. Numerical results indicated that, although many simplifications are assumed, such as the fault plane is planar and all heterogeneities are neglected, distribution of slip is still consistent roughly with the results of kinematic inversion, implying that for earthquakes in which ruptures run up directly to the ground surface, the dynamic processes are controlled by geometry of the fault to a great extent. By taking the common feature inferred by various kinematic inversion studies as a restriction, we found that the critical slip-weakening distance Dc should locate in a narrow region [60 cm, 70 cm], and supershear rupture might occur during this earthquake, if the initial shear stress before the mainshock is close to the local shear strength.

    2001-11-01

    We examine the mortality and morbidity associated with earthquakes in the Chi-Chi earthquake in Taiwan in 1999. Crude casualty data were collected from the reports of the government, local health bureaus, and 97 hospitals. The demographic data from the annual report of the Department of Interior were also employed for data analysis. Cross tables showing incidence of deaths and injuries by age, sex, time, and geographic distribution were generated to compare the mortality among different subgroups. Multiple regression models were established to explore the risk factors related to the mortality caused by earthquakes. The following results were found: the mortality rate increased with proximity to the epicenter, mortality was higher among the elderly than among young people, 30% of the victims died from head injuries caused by the collapse of dwellings, and the peak of medical demand was 12 hours after the earthquake and significantly increased demand for care lasted as long as 3 days. Furthermore, the regression model indicated that 78.5% of the variation of locality-age-sex-specific mortality was explained by the intensity of the earthquake, age, population density, distance to epicenter, medical beds per 10,000 people, and physicians per 10,000 people. The results implied that fragile minorities, specifically the elderly and children, require special consideration and attention in regard to disaster rescue and emergency medical care allocation. Epidemiologic analysis can guide disaster response and preparation.

    Bernal, Tula; Mendoza, Sergio

    2015-01-01

    In this article we perform a fourth order perturbation analysis of the gravitational metric theory of gravity \\( f(\\chi) = \\chi^{3/2} \\) developed by \\citet{bernal11a} and \\citet{mendoza13}. We show that the theory accounts in detail for the mass from the observations of 12 {\\textit{Chandra}} X-ray clusters of galaxies, without the need of dark matter. The dynamical observations can be synthesised in terms of the metric coefficients of the metric theory of gravity to the fourth order of approximation \\(O(4)\\), in perturbations of $v/c$. In this sense, we calculate the first relativistic correction of the theory, which is relevant at the outer regions of clusters of galaxies, in order to reproduce the observations. Also, we extended the computational MEXICAS (Metric EXtended-gravity Incorporated through a Computer Algebraic System) code, publicly available, developed for its usage in the Computer Algebraic System (CAS) Maxima for working out perturbations on any metric theory of gravity.

    2015-04-01

    Full Text Available Applied researchers have employed chi-square tests for more than one hundred years. This paper addresses the question of how one should follow a statistically significant chi-square test result in order to determine the source of that result. Four approaches were evaluated: calculating residuals, comparing cells, ransacking, and partitioning. Data from two recent journal articles were used to illustrate these approaches. A call is made for greater consideration of foundational techniques such as the chi-square tests.

    Full Text Available Tai Ji Quan is considered to be a part of traditional Chinese Wushu (a martial art and comprises various styles that have evolved historically from the Chen, Yang, Wǔ, Wú, and Sun families (schools. Recent simplification of the original classic styles has made Tai Ji Quan easier to adopt in practice. Thus, the traditional legacy of using Tai Ji Quan for self-defense, mindful nurturing of well-being, and fitness enhancement has been expanded to more contemporary applications that focus on promoting physical and mental health, enhancing general well-being, preventing chronic diseases, and being an effective clinical intervention for diverse medical conditions. As the impact of Tai Ji Quan on physical performance and health continues to grow, there is a need to better understand its historical impact and current status. This paper provides an overview of the evolution of Tai Ji Quan in China, its functional utility, and the scientific evidence of its health benefits, as well as how it has been a vehicle for enhancing cultural understanding and exchanging between East and West.

    We investigate in detail the linear regime of the modulational instability (MI) properties of the plane waves of the nonlocal model for chi((2))- media formulated in Nikolov et al. [N.I. Nikolov, D. Neshev, O. Bang, W.Z. Krolikowski, Quadratic solitons as nonlocal solitons, Phys. Rev.

We also show that the MI analysis for the nonlocal model is applicable in the finite walk-off case. Finally, we show that the plane waves of the nonlocal chi((2))-model...... of the nonlocal chi((2))-model, by using the singular perturbational approach. The other branch of the plane waves (i.e. the nonadiabatic branch or the optical branch) is always modulationally unstable. We compare the MI results for the adiabatic branch with the predictions obtained from the full chi((2))-model...

  14. Chi-square test and its application in hypothesis testing

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available In medical research, there are studies which often collect data on categorical variables that can be summarized as a series of counts. These counts are commonly arranged in a tabular format known as a contingency table. The chi-square test statistic can be used to evaluate whether there is an association between the rows and columns in a contingency table. More specifically, this statistic can be used to determine whether there is any difference between the study groups in the proportions of the risk factor of interest. Chi-square test and the logic of hypothesis testing were developed by Karl Pearson. This article describes in detail what is a chi-square test, on which type of data it is used, the assumptions associated with its application, how to manually calculate it and how to make use of an online calculator for calculating the Chi-square statistics and its associated P-value.

    DNA rigidity is an important physical property originating from the DNA three-dimensional structure. Although the general DNA rigidity patterns in human promoters have been investigated, their distinct roles in transcription are largely unknown. In this paper, we discover four highly distinct human promoter groups based on similarity of their rigidity profiles. First, we find that all promoter groups conserve relatively rigid DNAs at the canonical TATA box [a consensus TATA(A/T)A(A/T) sequence] position, which are important physical signals in binding transcription factors. Second, we find that the genes activated by each group of promoters share significant biological functions based on their gene ontology annotations. Finally, we find that these human promoter groups correlate with the tissue-specific gene expression.

    Chi-square discriminatory veto is a computationally expensive signal based veto as it requires lots of computing time. This veto is applied to the triggers surviving the second stage of the pipeline in the inspiral searches. We shall make an attempt to understand the nature of this veto and whether we can predict the chi-square values of triggers surviving this computationally expensive veto. This veto helps us to discriminate real signals from those arising due to noise transients by measuring the goodness of fit quantity. We discuss here two separate approaches. One is purely analytical which is based on the power accumulated in a given frequency bin due to the presence of non-stationary and non-Gaussian noise. We know that sum of squares of Gaussian random variables follow a central chi-square distribution whereas in case on non-Gaussian noise they obey a non-central chi-square distribution and hence the mean value has a contribution from central part non-central parameter λ. We shall show that this non-central parameter λ is a function of signal to noise ratio (SNR) of the triggers. Thus enabling us to model the expected chi-square values of the triggers using the SNR. The second approach I will talk involves trying to obtain a parabolic fit to the measured chi-squared distribution for a range of values as a function of signal to noise ratio.

    Full Text Available Tai people are widely distributed in Thailand, Laos and southwestern China and are a large population of Southeast Asia. Although most anthropologists and historians agree that modern Tai people are from southwestern China and northern Thailand, the place from which they historically migrated remains controversial. Three popular hypotheses have been proposed: northern origin hypothesis, southern origin hypothesis or an indigenous origin. We compared the genetic relationships between the Tai in China and their "siblings" to test different hypotheses by analyzing 10 autosomal microsatellites. The genetic data of 916 samples from 19 populations were analyzed in this survey. The autosomal STR data from 15 of the 19 populations came from our previous study (Lin et al., 2010. 194 samples from four additional populations were genotyped in this study: Han (Yunnan, Dai (Dehong, Dai (Yuxi and Mongolian. The results of genetic distance comparisons, genetic structure analyses and admixture analyses all indicate that populations from northern origin hypothesis have large genetic distances and are clearly differentiated from the Tai. The simulation-based ABC analysis also indicates this. The posterior probability of the northern origin hypothesis is just 0.04 [95%CI: (0.01-0.06]. Conversely, genetic relationships were very close between the Tai and populations from southern origin or an indigenous origin hypothesis. Simulation-based ABC analyses were also used to distinguish the southern origin hypothesis from the indigenous origin hypothesis. The results indicate that the posterior probability of the southern origin hypothesis [0.640, 95%CI: (0.524-0.757] is greater than that of the indigenous origin hypothesis [0.324, 95%CI: (0.211-0.438]. Therefore, we propose that the genetic evidence does not support the hypothesis of northern origin. Our genetic data indicate that the southern origin hypothesis has higher probability than the other two hypotheses

  20. Effects of the hanging wall and footwall on peak acceleration during the Jiji (Chi-Chi), Taiwan Province, earthquake

    2001-01-01

    The M=7.6 Jiji (Chi-Chi) earthquake, Taiwan Province, on September 21, 1999 (local time) is a thrust fault style earthquake. The empirical attenuation relations of the horizontal and vertical peak ground accelerations (PGA) for the Jiji (Chi-Chi) earthquake are developed by regression method. By examining the residuals from the Jiji (Chi-Chi) earthquake-specific peak acceleration attenuation relations, it is found that there are systematic differences between PGA on the hanging-wall and footwall. The recorded peak accelerations are higher on the hanging-wall and lower on the footwall. The clear asymmetry of PGA distribution to the surface rupture trace can also be seen from the PGA contour map. These evidences indicate that the PGA attenuates faster on the hanging-wall than on the footwall. In the study of near-source strong motion, seismic hazard assessment, scenario earthquake and seis-mic disaster prediction, the style-of-faulting must be considered in order that the attenuation model can reflect the characteristic of ground motion in various seismic environmental regions.

    The purpose of this study is to analyze variability in rainfall threshold for debris flow (critical rainfall for debris flow triggering) after the ML 7.3 Chi-Chi earthquake in central Taiwan in 1999.Two study sites with different geological conditions were surveyed in the earthquake area. Streambed surveys were conducted to continuously monitor debris flows between 1999 and 2006. During the 7-year study period, every debris flow event was identified, and the streambed characterized. Results show that the rainfall threshold for debris flow was remarkably lower just after the Chi-ChiEarthquake, but gradually recovered. To date, this rainfall threshold is still lower than the original level prior to the earthquake. This variability in rainfall threshold is closely related to the amount of sediment material in the initiation area of debris flow, which increased rapidly due to landslides resulting from the earthquake. With the increase in sediment material, the rainfall threshold was lowered severely during the first year following the Chi-Chi earthquake. However, heavy rainfalls mobilized the sediment material, causing debris flows and transporting sediment downstream. With the decrease in sediment material, the rainfall threshold recovered gradually over time. Furthermore,debris flows occurred only in the subbasins that had sufficient sediment material to cause significant movement. Hence, these results confirm that the sediment material in the initiation area of debris flow is a crucial component of the rainfall threshold for debris flow.

    Traditional patch-based sparse representation modeling of natural images usually suffer from two problems. First, it has to solve a large-scale optimization problem with high computational complexity in dictionary learning. Second, each patch is considered independently in dictionary learning and sparse coding, which ignores the relationship among patches, resulting in inaccurate sparse coding coefficients. In this paper, instead of using patch as the basic unit of sparse representation, we exploit the concept of group as the basic unit of sparse representation, which is composed of nonlocal patches with similar structures, and establish a novel sparse representation modeling of natural images, called group-based sparse representation (GSR). The proposed GSR is able to sparsely represent natural images in the domain of group, which enforces the intrinsic local sparsity and nonlocal self-similarity of images simultaneously in a unified framework. In addition, an effective self-adaptive dictionary learning method for each group with low complexity is designed, rather than dictionary learning from natural images. To make GSR tractable and robust, a split Bregman-based technique is developed to solve the proposed GSR-driven ℓ0 minimization problem for image restoration efficiently. Extensive experiments on image inpainting, image deblurring and image compressive sensing recovery manifest that the proposed GSR modeling outperforms many current state-of-the-art schemes in both peak signal-to-noise ratio and visual perception.

    Full Text Available Packet classification is a ubiquitous and key building block for many critical network devices. However, it remains as one of the main bottlenecks faced when designing fast network devices. In this paper, we propose a novel Group Based Search packet classification Algorithm (GBSA that is scalable, fast, and efficient. GBSA consumes an average of 0.4 megabytes of memory for a 10 k rule set. The worst-case classification time per packet is 2 microseconds, and the preprocessing speed is 3 M rules/second based on an Xeon processor operating at 3.4 GHz. When compared with other state-of-the-art classification techniques, the results showed that GBSA outperforms the competition with respect to speed, memory usage, and processing time. Moreover, GBSA is amenable to implementation in hardware. Three different hardware implementations are also presented in this paper including an Application Specific Instruction Set Processor (ASIP implementation and two pure Register-Transfer Level (RTL implementations based on Impulse-C and Handel-C flows, respectively. Speedups achieved with these hardware accelerators ranged from 9x to 18x compared with a pure software implementation running on an Xeon processor.

  5. Strong ground motion in the Taipei basin from the 1999 Chi-Chi, Taiwan, earthquake

    The Taipei basin, located in northwest Taiwan about 160 km from the epicenter of the Chi-Chi earthquake, is a shallow, triangular-shaped basin filled with low-velocity fluvial deposits. There is a strong velocity contrast across the basement interface of about 600 m/sec at a depth of about 600-700 m in the deeper section of the basin, suggesting that ground motion should be amplified at sites in the basin. In this article, the ground-motion recordings are analyzed to determine the effect of the basin both in terms of amplifications expected from a 1D model of the sediments in the basin and in terms of the 3D structure of the basin. Residuals determined for peak acceleration from attenuation curves are more positive (amplified) in the basin (average of 5.3 cm/ sec2 compared to - 24.2 cm/sec2 for those stations outside the basin and between 75 and 110 km from the surface projection of the faulted area, a 40% increase in peak ground acceleration). Residuals for peak velocity are also significantly more positive at stations in the basin (31.8 cm/sec compared to 20.0 cm/sec out). The correlation of peak motion with depth to basement, while minor in peak acceleration, is stronger in the peak velocities. Record sections of ground motion from stations in and around the Taipei basin show that the largest long-period arrival, which is coherent across the region, is strongest on the vertical component and has a period of about 10-12 sec. This phase appears to be a Rayleigh wave, probably associated with rupture at the north end of the Chelungpu fault. Records of strong motion from stations in and near the basin have an additional, higher frequency signal: nearest the deepest point in the basin, the signal is characterized by frequencies of about 0.3 - 0.4 Hz. These frequencies are close to simple predictions using horizontal layers and the velocity structure of the basin. Polarizations of the S wave are mostly coherent across the array, although there are significant

    Full Text Available The aim of this paper is to identify and evaluate the underlying factors affecting consumer acceptance of functional foods. The contribution of this study is to better understand customer willingness to buy such products in Ho Chi Minh City by shedding light on how socio-demographic, cognitive and attitudinal determinants affect consumer's choices of foods. We conducted a survey using 217 respondents from Ho Chi Minh City. Next, we develop a binary-probit model to quantify the impact of each factor on consumer acceptance. The results show that having a sick relative, beliefs in health benefits positively affect acceptance level. Other than that, old people in Ho Chi Minh City tend to reject the use of functional foods. However, when they are provided with enough knowledge, they are the most intensive buyers of these products. Implications and further researches are also discussed.

  8. So much research, so little application: Barriers to dissemination and practical implementation of Tai Ji Quan

    Full Text Available Despite the large number of articles published in the medical literature advocating the use of Tai Ji Quan for a wide variety of health-related outcomes, there has been little systematic broad-scale implementation of these programs. It may be argued that the lack of funding from organizations capable of implementing and overseeing large-scale programs, such as governmental health agencies or national non-governmental organizations concerned with healthcare for older adults, is to blame. However, the evidence these organizations need to justify underwriting such programs is in short supply because of conflicting priorities and standards related to determining the efficacy and effectiveness of Tai Ji Quan. Establishing efficacy through acceptable designs such as randomized controlled trials involves strict protocols to ensure meaningful internal validity but different approaches are needed to demonstrate meaningful effectiveness (external validity outside the study setting. By examining the quality, quantity, and relative proportions of the randomized controlled trials, systematic reviews, and dissemination studies reported in the medical literature, this paper highlights the disparity in emphasis between efficacy and effectiveness research that has impeded the development of a cohesive literature on Tai Ji Quan and concludes that until more researchers develop a systematic, long-range commitment to investigating its health-related benefits, the research related to Tai Ji Quan will remain fractured and sporadic, limiting the incentive of large funding agencies to support its wide-spread use.

    2014-08-01

    This is a review of the physiology and endocrinology of the estrous cycle and how ovarian physiology can be manipulated and controlled for timed artificial insemination (TAI) in beef and dairy cattle. Estrus detection is required for artificial insemination (AI), but it is done poorly in dairy cattle and it is difficult in beef cattle. Protocols that synchronize follicle growth, corpus luteum regression and ovulation, allowing for TAI, result in improved reproductive performance, because all animals are inseminated whether they show estrus or not. As result, TAI programs have become an integral part of reproductive management in many dairy herds and offer beef producers the opportunity to incorporate AI into their herds. Gonadotropin-releasing hormone-based protocols are commonly used in North America for estrus synchronization as part of a TAI program. Protocols that increase pregnancy rates in lactating dairy cows and suckling beef cows have been developed. Protocols that improve pregnancy rates in heifers, acyclic beef cows, and resynchronized lactating dairy cows are also discussed.

  13. A CHI wiggler ubitron amplifier experiment: Wiggler characterization

    A 35 GHz CHI (Coaxial Hybrid Iron) wiggler ubitron amplifier experiment is under construction at the Naval Research Laboratory. The CHI wiggler configuration has the potential of generating high wiggler magnetic fields at short periods with excellent beam focusing and transport properties. This makes it a desirable configuration for the generation of high power coherent radiation in relatively compact systems. The CHI wiggler consists of alternating rings of magnetic and non-magnetic materials concentric with a central rod of similar alternating design but shifted along the axis by half a period. Once inserted in a solenoidal magnetic field, the CHI structure deforms the axial field to create a radial field oscillating with the same periodicity as the rings. An annular electron beam is propagated through the coaxial gap where the oscillating radial field imparts an azimuthal wiggle motion. The principal goals of the experiment are to investigate the performance tradeoffs involved in the CHI configuration for high frequency amplifiers operating at low voltages with small wiggler periods. The nominal design parameters are a center frequency of 35 GHz, wiggler period of 0.75 cm, and beam voltage of approximately 150 kV. Calculations have shown an intrinsic (untapered) efficiency of {approximately} 7% when operating at 6.3 kG axial field (wiggler field, B{sub w}{approximately}1270 G). The calculated gain was 36 dB, saturating at a distance of 46 cm. These parameters yield an instantaneous amplifier bandwidth of {approximately} 25%. There appears to be room for further improvement in efficiency, a matter which will be scrutinized more closely in the final design. A prototype CHI wiggler is presently being fabricated for use in conjunction with an existing 30 kG superconducting solenoid. The performance properties of the prototype will be characterized and compared with linear and non-linear calculations.
