A Phenomenological Qualitative Exploration of Mind-Body Therapy Use and Effectiveness Among Young, Middle, and Older Adult Cancer Survivors.

BACKGROUND: Having been diagnosed with and treated for cancer can have negative psychosocial repercussions that may differ across the lifespan. Mind-body therapies (MBTs), such as tai-chi/qigong (TCQ) or mindfulness-based cancer recovery (MBCR), have shown promise in decreasing negative psychosocial outcomes in cancer survivors, but few studies have explored potential differences in MBT use and effectiveness across age groups. METHODS: A descriptive phenomenological qualitative design was used. Participants included young (18-39), middle (40-64), and older (65+) adult cancer survivors who were diagnosed with any type of cancer and had participated in Mindfulness-Based Cancer Recovery (MBCR) or Tai Chi/Qigong (TCQ) MBTs. Semi-structured qualitative interviews explored participants' experiences in MBTs and these were analyzed using descriptive phenomenological analysis. RESULTS: Among the interviews (n = 18), young (n = 6), middle-aged (n = 8), and older (n = 4) adults participated. 5 themes emerged: influences in joining the program, unique lifestyles, positive class experiences, use of media, and program impacts. Though all age groups benefitted from MBT participation, variations between age groups with respect to the benefits received and motivations for joining the program were observed. DISCUSSION: MBTs had beneficial physical and mental health effects on survivors of all age groups. These benefits were particularly connected to the ongoing life stresses common to each age cohort, such as relief from work and family roles for young adults or support during retirement transition for older adults. Hence, access to MBT programs may be beneficial as part of the survivorship plan for patients and the recruitment strategies or content can be adapted by MBT providers to better target and support age-specific groups. More research is required with a larger sample.

Effectiveness of Resistance Band Use in Conjunction With Tai Chi Among Older Adults With Prefrailty to Improve Functional Fitness, Quality of Life, and Heart Rate Variability.

PURPOSE: The current randomized controlled trial aimed to bolster the physical fitness of prefrail older adults, potentially delaying their need for admission to care facilities and enhancing their overall well-being. METHOD: The experimental group received a physical fitness intervention comprising resistance band use and tai chi three times per week for 12 weeks, whereas the control group received frailty-related health education. Thirty-four male participants completed the study. RESULTS: A total of seven items had statistically significant differences at 12- and 16-week posttest, respectively: frailty index (p = 0.03; p = 0.03); Instrumental Activities of Daily Living Scale (p < 0.001; p < 0.001); and physical fitness, back (p < 0.001; p < 0.001); physical fitness, arm curl (p = 0.02; p < 0.001); physical activity (p < 0.001; p = 0.009); quality of life, physiological (p = 0.04; p < 0.001); and heart rate variability (p < 0.001; p < 0.001). CONCLUSION: Results revealed substantial improvements in physical fitness, frailty conditions, self-care abilities, and quality of life, but not balance or lower limb flexibility, for the experimental group. Therefore, exercise interventions may effectively improve prefrail older adults' quality of life. [Journal of Gerontological Nursing, 50(5), 19-26.].

Tai Chi Chuan evidence related to impulsivity and impulse related disorders: A scoping review.

BACKGROUND: The purpose of this study was to review the evidence for the potential of Tai Chi Chuan (TCC) as a model of meditative movement in benefiting people with impulsivity related disorders and provide guidance for future research. METHODS: A scoping review of the literature was conducted in five databases. Eligibility criteria were original articles reporting TCC based interventions or included TCC techniques and provided any assessment on impulsivity or related measures, impulse control disorders, or other psychiatric disorders related to impulsivity (e.g., addictive disorders, ADHD, and other conduct disorders). Twenty-eight out of 304 studies initially retrieved were reviewed. The reports concentrated mostly on neurodegenerative conditions, cognitive decline, and substance use disorders (SUD). RESULTS: TCC had several positive effects in cognitive domains resulting in improvements in memory, executive functions, inhibitory control, attention, and verbal fluency. These improvements in memory, executive function, including inhibitory control and attention, and verbal fluency were associated with changes in the brain plasticity, resting activity, and other neurobiological markers. CONCLUSION: Albeit no study was found on the use of TCC in impulse control disorders or impulse related conditions, other than SUD, the findings suggest that considering the behavioral impact of TCC, especially the improvement of executive functions, it could be a valuable therapeutic tool for approaching impulse control related disorders.

Effectiveness of Tai Chi as a non-invasive intervention for mild cognitive impairment in the elderly: A comprehensive review and meta-analysis.

The aging population warrants the increase of mild cognitive impairment (MCI) prevalence, a condition that could progress to dementia. Efforts have been made to improve the MCI and prevent its progression, including the introduction of Tai Chi, a Chinese traditional exercise. The aim of this systematic review and meta-analysis was to evaluate the efficacy of Tai Chi in attenuating MCI among the elderly population. Records investigating the effect of Tai Chi exercise intervention on cognitive function among elderly patients were searched systematically from PubMed, ScienceDirect, Google Scholar, and Europe PMC as of April 13, 2023. The risk of bias (RoB 2.0) quality assessment was employed in the quality appraisal of the studies included. Review Manager 5.4.1 was used for data extraction and meta-analysis, where the standard mean difference (SMD) and 95% confidence interval (95%CI) were computed. Eight randomized control trials with a total of 1379 participants were included in this meta-analysis. Six trials assessed Montreal Cognitive Assessment scores, where its pooled analysis suggested that Tai Chi was as effective as conventional exercise (SMD=0.15, 95%CI: -0.11 to 0.40, p=0.26). However, pooled analysis of the Mini-Mental Status Examination suggested that Tai Chi intervention more effectively improved cognitive function and reduced the rate of cognitive impairment in elderly patients (SMD=0.36, 95%CI: 0.18 to 0.54, p<0.01) as compared to the control group. This systematic review and meta-analysis suggest that, in some extent, Tai Chi is efficacious in improving cognitive function and slowing down the rate of cognitive impairment among elderly patients.

Efficacy of exercise treatments for chronic obstructive pulmonary disease: A systematic review.

OBJECTIVE: To review the efficacy of exercise treatments on chronic obstructive pulmonary disease (COPD). DATA SOURCES: PubMed, Scopus, Science Direct, Ebscohost, SPORTDiscus, ProQuest, Web of Science. REVIEW METHODS: A systematic review was performed to identify the relevant studies published from 2011 to 2023. Studies were selected using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 5170 articles were retrieved and assessed using the Physiotherapy Evidence Database (PEDro) scale. The risk of bias in individual studies was assessed with the Cochrane risk of bias tool. RESULTS: A total of 38 eligible studies were included. Eight studies evaluated the effects of Tai Chi, followed by Liuzijue (five studies) and yoga (three studies). The duration of the exercise programmes ranged from 8 weeks to 3 years, and the frequency was between 2 and 7 times a week. Exercise sessions lasted between 20 and 90 min. Low-intensity exercise improved lung function after six months. Whole-body exercise improved dyspnea more than local exercise. Water-based exercise improved physical endurance more than land exercise, and quality of life was unaffected by long-term exercise. CONCLUSION: This systematic review highlights the benefit of exercise treatments as a potential adjunct treatment for COPD patients.

Tai chi, irisin and cognitive performance: a clinical and biological investigation in older adults.

BACKGROUND: Skeletal muscle is the main source of circulating irisin, both at rest and during physical activity. Previous studies have suggested that irisin can improve cognitive abilities. AIMS: We explored whether six months of Tai Chi (TC) practice can modulate such a relationship in healthy older persons. METHODS: This is a prospective clinical study to evaluate the effects of TC practice as compared with low intensity exercise (LI) and no exercise (NE) control groups on plasmatic irisin levels and cognitive performance. Forty-two healthy older persons were stratified into three groups according to physical activities. Biochemical assay and cognitive functions were assessed at the baseline and after six months. RESULTS: A significant change was found in circulating irisin levels in TC as compared with NE group (p = 0.050) across time. At six months in TC group irisin levels significantly correlated with a verbal memory test (p = 0.013) controlled by age and education. CONCLUSION: Our results suggest the potential benefits for cognitive health of TC practice by irisin levels modulation.

Effects of mind-body exercise on perimenopausal and postmenopausal women: a systematic review and meta-analysis.

IMPORTANCE: The increasing attention to the management of perimenopausal and postmenopausal women parallels the growth of the aging population. Although hormone therapy is commonly used to alleviate menopausal symptoms, it carries a potential risk of cancer. Recently, mind-body exercises have emerged as innovative approaches for improving menopausal symptoms and bone health. However, research findings have needed to be more consistent, highlighting the significance of this study's systematic review of mind-body exercise effects on perimenopausal and postmenopausal women. OBJECTIVE: This study aims to evaluate the impact of mind-body exercises, including tai chi, yoga, Pilates, qigong, baduanjin, and mindfulness-based stress reduction, on bone mineral density, sleep quality, anxiety, depression, and fatigue among perimenopausal and postmenopausal women. EVIDENCE REVIEW: Four electronic databases-PubMed, Embase, Cochrane Central Register of Controlled Trials, and Web of Science-were systematically searched from inception until July 2023. The search focused exclusively on randomized controlled trials to examine the impact of mind-body exercise interventions on perimenopausal and postmenopausal women. The methodological quality of the included studies was evaluated using the Cochrane Bias Risk Assessment tool. FINDINGS: A total of 11 randomized controlled trials, comprising 1,005 participants, were included in the analysis. Traditional meta-analysis indicated that mind-body exercise significantly enhanced bone mineral density in perimenopausal and postmenopausal women compared with control groups, with a standardized mean difference (SMD) of 0.41 (95% CI, 0.17 to 0.66; P = 0.001, I2 = 7%). In addition, significant improvements were observed in sleep quality (SMD, -0.48; 95% CI, -0.78 to -0.17; P = 0.002, I2 = 76%), anxiety reduction (SMD, -0.80; 95% CI, -1.23 to -0.38; P = 0.0002, I2 = 84%), depressive mood (SMD, -0.80; 95% CI, -1.17 to -0.44; P < 0.0001, I2 = 79%), and fatigue (SMD, -0.67; 95% CI, -0.97 to -0.37; P < 0.0001, I2 = 0%). CONCLUSIONS AND RELEVANCE: The findings of this meta-analysis demonstrate that mind-body exercise positively influences bone mineral density, sleep quality, anxiety, depression, and fatigue among perimenopausal and postmenopausal women.

Multicomponent Intervention on Improving the Cognitive Ability of Older Adults with Mild Cognitive Impairment: A Pilot Randomized Controlled Trial.

This pilot randomized controlled trial aimed to evaluate the feasibility and potential outcomes of an innovative 16-session multicomponent intervention model to improve cognitive abilities in older adults with mild cognitive impairment (MCI) by promoting healthy lifestyle, cognitive skills, tai chi and mindfulness practices. This study was a multicentre, randomized controlled, two-arm, parallel-group, unblinded trial in Hong Kong. 57 Chinese older adults with MCI recruited from three local elderly centers were randomly assigned to either the control or intervention group. The study results support the feasibility and efficacy of the multicomponent intervention, and recommend future larger-scale randomized control trials.

The effects of different types of Tai Chi exercises on preventing falls in older adults: a systematic review and network meta-analysis.

OBJECTIVES: Few studies comparing the effects of different types of Tai Chi exercises on preventing falls in older adults. We compared the effects for finding an optimal intervention. METHODS: We searched 12 databases, including PubMed, EMBASE, Cochrane Library, Chinese National Knowledge Infrastructure (CNKI) and so on, from their inception to January 13, 2023. Randomized controlled trials incorporating different types of Tai Chi for preventing falls in older adults were included. The outcome measures were the incidence of falls and Berg Balance Scale (BBS). Network meta-analysis (NMA) was conducted using Stata 15.1 based on a frequentist framework. RESULTS: Seventeen trials were eligible, including 3470 participants and four types of Tai Chi. They were 24-form simplified Tai Chi (24-form), Yang style Tai Chi (Yang style), Sun style Tai Chi (Sun style) and Tai Chi exercise program (TCEP). In paired meta-analysis, for incidence of falls, 24-form (Relative Risk (RR) = 0.59, 95% confidence interval (CI) [0.40, 0.86]) was more efficient than the control group. For BBS outcome, 24-form (MD (mean difference) = 2.32, 95% CI [1.42, 3.22]) was better than the control group. In the NMA, the results of incidence of falls were as follows: 24-form > Yang style > Sun style > control > TCEP. The rank probability of BBS was as follows: 24-form > TCEP > Yang style > control. CONCLUSION: Among the four types of Tai Chi studied, the 24-form simplified Tai Chi has shown better efficacy than other types.

Acute effects of different Tai Chi practice protocols on cardiac autonomic modulation.

Tai Chi serves as an effective exercise modality for enhancing autonomic regulation. However, a majority of existing studies have employed the single routine (SR) protocol as the basis for health interventions. The extent to which the gong routine application (GRA) protocol achieves similar levels of exercise load stimulation as traditional single practice routines remains uncertain. Therefore, this study the distinct characteristics of autonomic load stimulation in these different protocols, thus providing a biological foundation to support the development of Tai Chi health promotion intervention programs. we recruited a cohort of forty-five university students to participate in the 15 min GRA protocol and SR protocol. We collected heart rate and heart rate variability indicators during periods of rest, GRA protocol, and SR protocol utilizing the Polar Scale. Additionally, we assessed the mental state of the participants using the BFS State of Mind Scale. In summary, the autonomic load is lower in the GRA protocol compared to the SR protocol, with lower sympathetic activity but higher parasympathetic activity in the former. Results are specific to college students, additional research is necessary to extend support for frail older adults. It is advised to incorporate GRA protocol alongside SR protocol in Tai Chi instruction. This approach is likely to enhance Tai Chi skills and yield greater health benefits.

The effect of Tai Chi lower extremity exercise on the balance control of older adults in assistant living communities.

BACKGROUND: Although Tai Chi (TC) is an evidence-based fall prevention training for older adults, its effective movements remain unclear, which may limit the practice of TC. The purpose of this study was to compare the effectiveness of TC lower extremity exercise (TC LEE), the 8-form Tai Chi (8-form TC), and a stretching control intervention for improving balance and functional mobility among older adults. METHODS: This was a randomized controlled trial. A total of 102 participants (79 ± 6 years old) were recruited from assisted living facilities. All participants were randomly assigned to the TC LEE (n = 40), 8-form TC (n = 31), and stretching (n = 31) groups in which they received the respective interventions for 16 weeks. The Berg Balance Scale (BBS), Timed Up and Go (TUG) test, and center of pressure (COP) measurements during quiet stance were collected prior to and following the 16-week interventions. Comparisons on all measurements were conducted among all groups. RESULTS: Significant improvements were found in BBS (P = 0.002), TUG test (P = 0.001), root mean square amplitude of COP displacement in the anterior-posterior (P = 0.001) and medial-lateral (P = 0.001) directions, and average COP speed in the anterior-posterior (P = 0.001) and medial-lateral (P = 0.001) directions after training in the TC intervention groups compared with the stretching group. The upper limit of the 95% confidence interval (CI) of differences in change scores on the BBS (-0.8 - 1.3 points) between the TC LEE group and the 8-form TC group was within equivalence margins (1.8 points), while the upper limit of the 95% CI of differences in change scores on the TUG test (0.1 - 2.1 s) exceeded the equivalence margin (0.7 s) with the TC LEE group having the larger change scores. CONCLUSION: TC LEE can improve balance and functional mobility in older adults, and may have greater effect than the 8-form TC on improving functional mobility as measured by the TUG test. TRIAL REGISTRATION: ChiCTR2300070600 retrospectively registered.

Estrategias de intervención motora sobre el control postural en niños y jóvenes con trastorno del espectro autista: una revisión sistemática / Motor intervention strategies on postural control in children and youth with autism spectrum disorder: A systematic review

El trastorno del espectro autista (TEA) posee características variadas con un impacto a nivel social, comunicativo y sensoriomotor (SM). Una característica SM son los problemas sobre el control postural (CP). Variadas son las estrategias de intervención motora (EIM), pero el beneficio sobre el CP es algo que se ha analizado de forma menos amplia. El objetivo fue describir las EIM y sus resultados sobre el CP de niños y adolescentes con TEA. Se realizó una búsqueda en PubMed, Scopus, Web of Science y Cochrane. Un total de ocho artículos cumplieron con los criterios de elegibilidad. Todas las EIM mostraron resultados beneficiosos sobre el mejoramiento del CP y fueron de diferente naturaleza (práctica de bailes, actividad física personalizada, videojuegos, Tai Chi Chuan, Taekwondo y realidad virtual). Es necesario mejorar los diseños y considerar los riesgos de sesgos, pues limitan el alcance de los resultados.(AU)

Autism spectrum disorder (ASD) has varied characteristics with an impact at the social, communicative and sensorimotor (SM) level. An SM feature is postural control (PC) problems. There are various motor intervention strategies (MIS), but the benefit over LC is something that has been analyzed less extensively. The objective was to describe the MIS and its results on the PC of children and adolescents with ASD. A search of PubMed, Scopus, Web of Science and Cochrane was performed. A total of eight articles met the eligibility criteria. All MIS showed beneficial results on the improvement of PC. The MIS were of a varied nature (dance practice, personalized physical activity, video games, Tai Chi Chuan, Taekwondo and virtual reality). It is necessary to improve the designs and consider the risks of bias, since they limit the scope of the results.(AU)

Metabolic impairments associated with type 2 diabetes mellitus and the potential effects of exercise therapy: An exploratory randomized trial based on untargeted metabolomics.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a common condition that is characterized by metabolic impairments. Exercise therapy has proven effective in improving the physiological and psychological states of patients with T2DM; however, the influence of different exercise modalities on metabolic profiles is not fully understood. This study first aimed to investigate the metabolic changes associated with T2DM among patients and then to evaluate the potential physiological effects of different exercise modalities (Tai Chi and brisk walking) on their metabolic profiles. METHODS: This study included 20 T2DM patients and 11 healthy subjects. Patients were randomly allocated to either the Tai Chi or walking group to perform Dijia simplified 24-form Tai Chi or brisk walking (80-100 m/min), with 90 minutes each time, three times per week for 12 weeks, for a total of 36 sessions. The healthy group maintained daily living habits without intervention. Glycemic tests were conducted at the baseline and after 12 weeks. Serum and urine samples were collected for untargeted metabolomic analyses at baseline and 12 weeks to examine the differential metabolic profiles between T2DM and healthy subjects, and the metabolic alterations of T2DM patients before and after exercise therapy. RESULTS: Compared to the healthy group, T2DM patients exhibited metabolic disturbances in carbohydrates (fructose, mannose, galactose, glycolysis/gluconeogenesis), lipids (inositol phosphate), and amino acids (arginine, proline, cysteine, methionine, valine, leucine, and isoleucine) metabolism, including 20 differential metabolites in the serum and six in the urine. After exercise, the glycemic results showed insignificant changes. However, patients who practiced Tai Chi showed significant improvements in their post-treatment metabolic profiles compared to baseline, with nine serum and six urine metabolites, including branch-chained amino acids (BCAAs); while those in the walking group had significantly altered nine serum and four urine metabolites concerning steroid hormone biosynthesis and arachidonic acid metabolism compared to baseline. CONCLUSION: T2DM patients displayed impaired carbohydrate, lipid, and amino acid metabolism, and exercise therapy improved their metabolic health. Different modalities may act through different pathways. Tai Chi may improve disrupted BCAAs metabolism, whereas brisk walking mainly regulates steroid hormone biosynthesis and arachidonic acid metabolism.

Enhancing Tai Chi Training System: Towards Group-Based and Hyper-Realistic Training Experiences.

In this article, we propose a lightweight and flexible enhanced Tai Chi training system composed of multiple standalone virtual reality (VR) devices. The system aims to enable a hyper-realistic multi-user action training platform at low cost by displaying real-time action guidance trajectories, providing real-world impossible visual effects and functions, and rapidly enhancing movement precision and communication interest for learners. We objectively evaluate participants' action quality at different levels of immersion, including traditional coach guidance (TCG), VR, and mixed reality (MR), along with subjective measures like motion sickness, quality of interaction, social meaning, presence/immersion to comprehensively explore the system's feasibility. The results indicate VR performs the best in training accuracy, but MR provides superior social experience and relatively high accuracy. Unlike TCG, MR offers hyper-realistic hand movement trajectories and Tai Chi social references. Compared with VR, MR provides more realistic avatar companions and a safer environment. In summary, MR balances accuracy and social experience.

Traditional Chinese exercises on depression: A network meta-analysis.

BACKGROUND: Exercise is an important factor for the treatment and rehabilitation of depression. Traditional Chinese exercise is considered as an effective treatment for depression. In recent years, many studies have shown that Chinese exercise therapy may be safe in the treatment of depression. To evaluate the therapeutic effect of traditional Chinese exercise on depression using network meta-analysis. METHODS: PubMed, Cochrane Library, Web of Science, China National Knowledge Infrastructure, VIP shop Database, China Biomedical Literature Database, and Wan Fang Data Knowledge Service Platform were included in randomized controlled studies on traditional Chinese exercises for the treatment of depression from the establishment of the library to July 2023. The literature was extracted and assessed for risk of bias using the Cochrane Risk of Bias Assessment and statistically analyzed using Review Manager 5.4 and Stata 14.2. RESULTS: A total of 25 studies involving 3 exercises with a total of 1605 cases were included. The results of the network meta-analysis showed that each exercise significantly reduced the 24-item Hamilton Depression Scale (HAMD-24), Hamilton Anxiety Scale, Beck Depression Inventory, and Self-rating Depression Scale scores. However, conventional treatments have the advantage of improving the sleep quality of patients with depression. CONCLUSIONS: The 3 exercises included in this study were effective for depression. Baduanjin and Tai Chi were better at improving the outcomes related to depression and anxiety. The effect of sleep quality intervention was slightly worse. Larger, high-quality randomized controlled trials are needed to compare interventions across exercises in a more granular manner.

Tai Chi training as a primary care plan for the prevention and management of hypertension: an opinion and positioning article.

Hypertension is a prevalent chronic condition worldwide that can impact patients' quality of life. Oral antihypertensive drugs are widely used to manage high blood pressure, primarily by regulating the renin-angiotensin-aldosterone system. Nevertheless, limited efficacy and low compliance represent significant obstacles, arising primarily from dose, duration, and medication type restrictions. Furthermore, the prolonged use of antihypertensive medication may result in dependence and adverse effects, without any substantial improvement in achieving targeted blood pressure leves. As a result, research has focused on using exercise therapy to treat hypertension. Tai Chi, a widely-practiced Chinese health exercise, has evolved into a form of exercise therapy that might help alleviate the risk associated with hypertension. Therefore, this article aims to outline the role of Tai Chi in preventing and managing hypertension.

Are Tai Chi and Qigong effective in the treatment of traumatic brain injury? A systematic review.

BACKGROUND: Traumatic brain injury (TBI) adversely affects both young and old and is a growing public health concern. The common functional, psychological, and cognitive changes associated with TBI and recent trends in its management, such as recommending sub-threshold aerobic activity, and multi-modal treatment strategies including vestibular rehabilitation, suggest that Tai Chi/Qigong could be beneficial for TBI. Tai Chi and Qigong are aerobic mind-body practices with known benefits for maintaining health and mitigating chronic disease. To date, no systematic review has been published assessing the safety and effectiveness of Tai Chi/Qigong for traumatic injury. METHODS: The following databases were searched: MEDLINE, CINAHL Cochrane Library, Embase, China National Knowledge Infrastructure Database, Wanfang Database, Chinese Scientific Journal Database, and Chinese Biomedical Literature Database. All people with mild, moderate, or severe TBI who were inpatients or outpatients were included. All Types of Tai Chi and Qigong, and all comparators, were included. All measured outcomes were included. A priori, we chose "return to usual activities" as the primary outcome measure as it was patient-oriented. Cochrane-based risk of bias assessments were conducted on all included trials. Quality of evidence was assessed using the grading of recommendation, assessment, development, and evaluation (GRADE) system. RESULTS: Five trials were assessed; three randomized controlled trials (RCTs) and two non-RCTs; only two trials were conducted in the last 5 years. No trial measured "return to normal activities" or vestibular status as an outcome. Four trials - two RCTs and two non-RCTS - all found Tai Chi improved functional, psychological and/or cognitive outcomes. One RCT had a low risk of bias and a high level of certainty; one had some concerns. One non-RCTs had a moderate risk of bias and the other a serious risk of bias. The one Qigong RCT found improved psychological outcomes. It had a low risk of bias and a moderate level of certainty. Only one trial reported on adverse events and found that none were experienced by either the exercise or control group. CONCLUSION: Based on the consistent finding of benefit in the four Tai Chi trials, including one RCT that had a high level of certainty, there is a sufficient signal to merit conducting a large, high quality multi-centre trial on Tai Chi for TBI and test it against current trends in TBI management. Based on the one RCT on TBI and Qigong, an additional confirmatory RCT is indicated. Further research is indicated that reflects current management strategies and includes adverse event documentation in both the intervention and control groups. However, these findings suggest that, in addition to Tai Chi's known health promotion and chronic disease mitigation benefits, its use for the treatment of injury, such as TBI, is potentially a new frontier.

Effects of tai chi, ba duan jin, and walking on the mental health status of urban older people living alone: the mediating role of social participation and the moderating role of the exercise environment.

With the global trend of aging, lacking of interpersonal communication and spiritual support and companionship have had a great impact on the mental health of older people living alone. This study examines the multifaceted impacts of engaging in tai chi, ba duan jin, and walking on the mental wellbeing of older people residing alone in urban areas. Additionally, this research aims to explore the association between tai chi, ba duan jin, and walking, and the mental health status of urban older people living alone, by considering the mediating influence of social participation and the moderating influence of the exercise environment. To do so, 1,027 older people living alone in six Chinese cities were investigated using the Physical Activity Rating Scale (PARS-3), the Geriatric Health Questionnaire (GHQ-12), the Social Participation Indicator System Scale, and the Exercise Environment Scale. SPSS 25.0 was utilized for conducting mathematical statistical analysis, specifically for doing linear regression analysis. Additionally, AMOS was employed to develop the study model. We found that a significant negative correlation between tai chi, ba duan jin, and walking and mental health status; among these, tai chi had the greatest impact on the mental health status of urban older people living alone. Social participation mediated the relationship between tai chi, ba duan jin, walking, and mental health status, and the exercise environment had a moderating effect on this relationship. The findings of this study indicate that tai chi, ba duan jin, and walking have a positive impact on the mental health of urban older people living alone, which can be influenced by the mediating efficacy of social participation and the moderating effect of the exercise environment.

Effect of Tai Chi vs Aerobic Exercise on Blood Pressure in Patients With Prehypertension: A Randomized Clinical Trial.

Importance: Prehypertension increases the risk of developing hypertension and other cardiovascular diseases. Early and effective intervention for patients with prehypertension is highly important. Objective: To assess the efficacy of Tai Chi vs aerobic exercise in patients with prehypertension. Design, Setting, and Participants: This prospective, single-blinded randomized clinical trial was conducted between July 25, 2019, and January 24, 2022, at 2 tertiary public hospitals in China. Participants included 342 adults aged 18 to 65 years with prehypertension, defined as systolic blood pressure (SBP) of 120 to 139 mm Hg and/or diastolic BP (DBP) of 80 to 89 mm Hg. Interventions: Participants were randomized in a 1:1 ratio to a Tai Chi group (n = 173) or an aerobic exercise group (n = 169). Both groups performed four 60-minute supervised sessions per week for 12 months. Main Outcomes and Measures: The primary outcome was SBP at 12 months obtained in the office setting. Secondary outcomes included SBP at 6 months and DBP at 6 and 12 months obtained in the office setting and 24-hour ambulatory BP at 12 months. Results: Of the 1189 patients screened, 342 (mean [SD] age, 49.3 [11.9] years; 166 men [48.5%] and 176 women [51.5%]) were randomized to 1 of 2 intervention groups: 173 to Tai Chi and 169 to aerobic exercise. At 12 months, the change in office SBP was significantly different between groups by -2.40 (95% CI, -4.39 to -0.41) mm Hg (P = .02), with a mean (SD) change of -7.01 (10.12) mm Hg in the Tai Chi group vs -4.61 (8.47) mm Hg in the aerobic exercise group. The analysis of office SBP at 6 months yielded similar results (-2.31 [95% CI, -3.94 to -0.67] mm Hg; P = .006). Additionally, 24-hour ambulatory SBP (-2.16 [95% CI, -3.84 to -0.47] mm Hg; P = .01) and nighttime ambulatory SBP (-4.08 [95% CI, -6.59 to -1.57] mm Hg; P = .002) were significantly reduced in the Tai Chi group compared with the aerobic exercise group. Conclusions and Relevance: In this study including patients with prehypertension, a 12-month Tai Chi intervention was more effective than aerobic exercise in reducing SBP. These findings suggest that Tai Chi may help promote the prevention of cardiovascular disease in populations with prehypertension.
