Effects of long-term Tai Chi vs. aerobic exercise on antioxidant activity and cognitive function in individuals with Parkinson's disease.

An imbalance between the generation of reactive oxygen species and the body's antioxidant defense mechanisms is closely related to the development and progression of Parkinson's disease (PD). Considering that physical exercise is a potential therapeutic intervention for modulating oxidative stress markers and cognitive function in PD, the primary purpose of this study was to compare the effects of different long-term exercise modalities on antioxidants and cognitive performance in patients with PD. In addition, the secondary purpose was to explore whether changes in the levels of these biochemical markers are associated with alterations in cognitive performance pre- and post-intervention. In all, 61 participants were randomly divided into the aerobic exercise (AE, n=20), Tai Chi exercise (TCE, n=21), or control (n=20) group. Blood samples were collected before and after a 12-week intervention period for the analysis of antioxidant markers [leukocyte 8-hydroxydeoxyguanosine (8-OHdG), catalase (CAT), glutathione (GSH), glutathione peroxidase (GSH-Px), oxidized glutathione (GSSG), superoxide dismutase (SOD), and uric acid (UA)]. Cognitive function was evaluated using the Mini-Mental State Examination (MMSE). Although no significant changes were observed in the activity of 8-OhdG, GSH-Px, GSSG, GSH:GSSG ratio, SOD, and cognitive performance in the AE and TCE groups, the 12-week AE intervention led to a significant increase in CAT and GSH levels, along with a significantly decrease in UA levels among individuals with PD. Conversely, the TCE intervention resulted in a significant increase in GSH levels. However, SOD activity and MMSE scores were significantly decreased after 12 weeks in the control group. The correlations between changes in MMSE scores and changes in the levels of GSH and UA prior to and after the intervention reached significance in the AE group. Thus, long-term AE and TCE might serve as effective strategies for reducing oxidative damage and preserving cognitive function in PD, with AE exhibiting greater benefits compared with TCE. These findings hold potential clinical relevance as complementary measures to standard medical treatments and alternative therapies, such as antioxidant supplements and dietary adjustments, particularly for individuals in the early stages of PD.

Characteristic Changes of Prefrontal and Motor Areas in Patients with Type 2 Diabetes and Major Depressive Disorder During a Motor Task of Tai Chi Chuan: A Functional Near-Infrared Spectroscopy Study.

AIM: This cross-sectional study aims to identify the characteristic changes of prefrontal and motor areas during a tai chi chuan task in patients with Type 2 diabetes mellitus (T2DM) and major depressive disorder (MDD) using wearable functional near-infrared spectroscopy (fNIRS). METHODS: Three parallel groups (T2DM with DD group, T2DM group, and healthy group) were recruited from December 10, 2022, to May 31, 2023. Participants in three groups conducted a motor task of tai chi chuan designed by Eprime 3.0, and fNIRS was used to monitor the brain activation, functional connectivity (FC), and lateralization of prefrontal and motor areas. Correlation analyses were performed to examine the relationship between depressive symptoms and the function of prefrontal and motor areas. RESULTS: Ninety elder adults (aged ≥ 60), including 30 patients with T2DM and MDD, 30 patients with T2DM, and 30 healthy subjects, were enrolled. In contrast with the patients with T2DM and healthy subjects, the patients with T2DM and MDD had decreased activation and abnormal lateralization in prefrontal and motor areas and decreased FC among supplementary motor area, motor area, and dorsolateral prefrontal cortex (DLPFC). Furthermore, the oxyhemoglobin (HbO2) concentration value of DLPFC in patients with T2DM and MDD was negatively associated with scores of Hamilton Depression Scale-24 (HAMD-24). CONCLUSIONS: Patients with T2DM and MDD had characteristic functional changes in prefrontal and motor areas. DLPFC may be a potential target of diagnosis and intervention for patients with T2DM and MDD.

Evidence map of traditional Chinese exercises.

Objective: This study aimed to assess and visually depict the clinical evidence landscape of traditional Chinese exercises and identify any research gaps and future research needs. Methods: We comprehensively searched seven Chinese and English databases to identify randomized controlled trials (RCTs) and systematic reviews (SRs) evaluating the effects of traditional Chinese exercises from their inception until May 2023. The quality of evidence was assessed via the GRADE approach, and the research topics, intervention effects, and strength of evidence were graphically displayed. Results: This evidence map includes 2,017 studies, comprising 1,822 RCTs and 195 SRs. These studies were conducted globally in various countries. Among the traditional Chinese exercises, Tai Chi and Baduanjin have received the most research attention, with a growing number of publications. When traditional Chinese exercises were compared with the control groups, 88.2% of the included SRs reported significantly positive effects, 4.1% reported unclear effects, and 7.7% reported no significant differences. The findings suggested that traditional Chinese exercises could benefit patients with osteoarthritis, osteoporosis, hypertension, coronary heart disease, diabetes, chronic obstructive pulmonary disease, stroke, Parkinson's disease, anxiety, and depression. However, the overall quality of the evidence was suboptimal, with 11.3% rated as moderate, 45.6% as low, and 43.1% as critically low. Conclusion: This evidence map visually represents valuable information on traditional Chinese exercises. While most studies have reported significant benefits, the overall quality of evidence is low.

The impact of mind-body exercise on the quality of life in older adults: the chain mediation effect of perceived social support and psychological resilience.

Background: With the intensification of the global aging trend, there is a contradiction between the extended lifespan and the decline of physiological functions among the older adult. It has become a global consensus to focus on and improve the quality of life for the older adult. Mind-body exercises (Tai Chi, Ba Duan Jin, Yi Jin Jing) play a crucial role in promoting the quality of life for older adults, but the mechanisms and mediating effects are not yet clear. Objective: This study examines the impact of mind-body exercises (Tai Chi, Ba Duan Jin, Yi Jin Jing) on the quality of life in older adults, with a particular focus on exploring the chain mediating effects of perceived social support and psychological resilience. Methods: This study is a cross-sectional study that surveyed 1,087 older adults participating in mind-body exercises (Tai Chi, Ba Duan Jin, Yi Jin Jing) in 13 districts of Beijing, China, from March 25 to May 3, 2024. The Physical Activity Rating Scale (PARS-3), the World Health Organization Quality of Life Scale (WHOQOL-BREF), the Perceived Social Support Scale (PSSS), and the Connor-Davidson Resilience Scale (CD-RISC) were used to measure mind-body exercise, perceived social support, psychological resilience, and quality of life, respectively. Data were statistically analyzed using SPSS 26.0, and mediation effects were tested and effect analysis was conducted through structural equation modeling (AMOS) and the Bootstrap method. Results: The study results show that mind-body exercises (Tai Chi, Ba Duan Jin, Yi Jin Jing) are significantly and positively correlated with the quality of life in older adults (r = 0.549, p < 0.01). The path coefficients for the relationships mind-body exercise → perceived social support (ß = 0.46, p < 0.001) → psychological resilience (ß = 0.20, p < 0.001) → quality of life in older adults (ß = 0.39, p < 0.001) are significant, indicating that perceived social support and psychological resilience have a chain mediating effect between mind-body exercise and the quality of life in older adults. Conclusion: Mind-body exercises not only improve the quality of life for older adults but also indirectly enhance it by strengthening perceived social support and psychological resilience. This study provides significant reference for developing health intervention strategies targeted at older adults, suggesting that promoting mind-body exercises can improve their sense of perceived social support and psychological resilience, thereby increasing their quality of life.

The Effect of Tai Chi (Bafa Wubu) Training and Artificial Intelligence-Based Movement-Precision Feedback on the Mental and Physical Outcomes of Elderly.

(1) Background: This study aims to compare the effects of AI-based exercise feedback and standard training on the physical and mental health outcomes of older adults participating in a 4-week tai chi training program. (2) Methods: Participants were divided into three groups: an AI feedback group received real-time movement accuracy feedback based on AI and inertial measurement units (IMUs), a conventional feedback group received verbal feedback from supervisors, and a control group received no feedback. All groups trained three times per week for 8 weeks. Outcome measures, including movement accuracy, balance, grip strength, quality of life, and depression, were assessed before and after the training period. (3) Results: Compared to pre-training, all three groups showed significant improvements in movement accuracy, grip strength, quality of life, and depression. Only the AI feedback group showed significant improvements in balance. In terms of movement accuracy and balance, the AI feedback group showed significantly greater improvement compared to the conventional feedback group and the control group. (4) Conclusions: Providing real-time AI-based movement feedback during tai chi training offers greater health benefits for older adults compared to standard training without feedback.

Modified tai chi movement training based on sEMG and movement analysis on improving upper extremities motor function: a protocol for a clinical randomised controlled trial.

INTRODUCTION: Stroke survivors often face motor dysfunction, increasing fall risk. Lower extremity muscle weakness is a key factor affecting walking ability. Tai chi (TC) has been shown to improve muscle strength and mobility in patients with stroke more effectively than traditional walking training. However, existing TC programmes for stroke rehabilitation are often too simplified and fail to fully use TC's benefits. Additionally, subjective assessment scales are time-consuming and prone to bias. This study proposes integrating TC's early movement features with neurodevelopmental therapy, using surface electromyography and inertial measurement unit (IMU) sensors to thoroughly analyse diverse TC movements. Tailored exercises, based on stroke-induced impairments, will be objectively assessed through biomechanical analysis. METHODS AND ANALYSIS: The study unfolds in two phases. The initial phase employs the IMU sensor and electromyography to objectively analyse TC's biomechanics, informing personalised rehabilitation plans aligned with distinct movement impairments. The second phase adopts a randomised, single-blind, parallel controlled trial design involving 60 patients with stroke randomly assigned to either the intervention or control group. The intervention group undergoes biomechanics-based TC training alongside routine rehabilitation for 12 weeks, practicing the 24-form TC three times weekly. The control group engages in routine rehabilitation thrice weekly for the same duration. Primary and secondary outcomes, including kinematic/dynamic data, surface electromyography, motion analysis, comprehensive the international classification of functioning, disability and health Core Set for Stroke, Modified Barthel Index and Fugl-Meyer Assessment, will be evaluated at baseline and post-intervention. ETHICS AND DISSEMINATION: The study has received approval from the Ethics Committee of Zhongda Hospital Southeast University (2023ZDSYLL378-P01). All prospective participants will receive comprehensive information regarding the study protocol, and their informed consent will be obtained before their participation. Additionally, the trial will be registered with the Chinese Clinical Trial Registry to ensure transparency and compliance with research regulations. Results from this study will be disseminated through peer-reviewed journals, conference presentations and public databases to ensure wide accessibility and to contribute to the advancement of medical knowledge. PROTOCOL VERSION: 2.0 (14 June 2024). TRIAL REGISTRATION NUMBER: www.chictr.org.cn, identifier ChiCTR2400080158.

The influence of different intensity of Tan Tui exercises on the posture control of students in the Tai Chi Elective Course: protocol for a randomized controlled trial.

BACKGROUND: Tai Chi (TC) holds a unique and valued place in promoting the physical and mental health of college students. Its significance is underscored by its incorporation as a compulsory physical education course in every university in China. TC, with its rich tradition, places a strong emphasis on posture control as a core sports ability. However, the students in Tai Chi Elective Course (TCEC) have very poor posture control ability. This study protocol investigates the potential of Tan Tui (TT) to address these issues, as TT is a fundamental skill for beginners of traditional Chinese martial arts and has a track record of enhancing lower limb strength and balance, making it a promising choice for improving posture control in TCEC. METHODS/DESIGN: To investigate the impact of different intensities of TT exercises on posture control in TCEC students, we have designed a randomized, double-blind, parallel-controlled trial. Seventy-six students in the TCEC will be randomly divided into low-intensity Tan Tui (LTT), medium-intensity Tan Tui (MTT), and high-intensity Tan Tui exercises group (HTT) and control group (CON), each with 19 people. The LTT group, MTT group, and HTT group will be given different intensity of TT exercises, and the CON group will be given regular TCEC. The intervention period will be 6 weeks (2 times a week, 20 min each time). At baseline (before), 4 weeks of intervention (middle), and 6 weeks of intervention (after), the Unipedal Stance Test (UST), the Star Excursion Balance Test (SEBT), 60°/s angular velocity knee joint flexion and extension relative peak torque (RPT), and knee joint position perception (KJPP) will be evaluated. DISCUSSION: This is the first randomized controlled trial protocol from the perspective of training intensity to evaluate the effect of different intensity of TT exercises on posture control of students in TCEC. Should our research reveal a significant intervention effect, the results will offer preliminary, higher-quality evidence supporting the positive impact of varying intensities of Tan Tui exercises on posture control in TCEC students.

Impact of a Precision Intervention for Vascular Health in Middle-Aged and Older Postmenopausal Women Using Polar Heart Rate Sensors: A 24-Week RCT Study Based on the New Compilation of Tai Chi (Bafa Wubu).

(1) Background: This study utilized a 24-week intervention incorporating heart rate sensors for real-time monitoring of intervention training, aiming to comprehensively assess the effects of Tai Chi on vascular endothelial function, atherosclerosis progression, and lipid metabolism. The insights gained may inform personalized non-pharmacological interventions to enhance the management of cardiovascular health in this population to provide sustainable benefits and improve quality of life. (2) Methods: Forty postmenopausal middle-aged and elderly women were randomly assigned to an exercise or control group. The exercise group underwent a 24-week Tai Chi (BaFa WuBu) training intervention with real-time heart rate monitoring using Polar sensors. Pre- and post-intervention assessments included body composition, blood pressure, vascularity, and blood parameters measured with the Inbody 720, Vascular Endothelial Function Detector, and Arteriosclerosis. Data were analyzed using SPSS 26.0 and mixed-design ANOVA to assess the effects of time, group, and their interactions on study outcomes. (3) Results: After training through 24 weeks of Tai Chi (BaFa WuBu) intervention, compared with the control group, systolic blood pressure in the exercise group was significantly lower (p < 0.05), and the difference between left and right arm pulse pressure, left and right ankle mean arterial pressure, left and right side baPWV, left and right side ABI, TC, TG, LDL, and blood pressure viscosity were all very significantly lower (p < 0.01), and the diastolic blood pressure was significantly higher (p < 0.05). Compared with baseline values in the exercise group, systolic blood pressure, right and left arm pulse pressure difference, right and left ankle mean arterial pressure, right and left side baPWV, right and left side ABI, TC, TG, LDL, and blood pressure viscosity decreased very significantly (p < 0.01) and diastolic blood pressure and FMD increased very significantly (p < 0.01) in the exercise group after the intervention. (4) Conclusions: In our study, a 24-week Tai Chi (BaFa WuBu) program significantly improved vascular health in middle-aged and older postmenopausal women. This simplified Tai Chi form is gentle and effective, ideal for older adults. Regular practice led to reduced vascular obstruction, improved lipid metabolism, and enhanced vascular endothelial function, crucial for preventing vascular diseases. The real-time heart rate sensors used were pivotal, enabling precise monitoring and adjustment of exercise intensity, thereby enhancing the study's scientific rigor and supporting Tai Chi (BaFa WuBu) as a beneficial therapeutic exercise.

Nurse-led follow-up care versus routine health education and follow-up in diabetes patients: An effectiveness analysis.

Patients with diabetes have physical and psychological issues due to chronic illness. According to the guidelines of the Chinese Diabetes Society, after the diagnosis of patients with diabetes, they should receive routine health education, but this is the passive installation method of education. Nurses have made important contributions to the follow-up, education, and support of patients with diabetes and their families. The objective of this study was to evaluate the effectiveness of nurse-led follow-up care in routine health education and follow-up for patients with diabetes. Medical records of 721 patients with type 1 and type 2 diabetes were reviewed. Patients received nurse-led follow-up care including educational programs + Tai Chi exercises (patients received nurse-led follow-up care including educational programs for 6 months, n = 108), routine health education and follow-up + Tai Chi exercises (patients received routine health education and follow-up for 6 months, n = 205), or Tai Chi exercises only, but did not receive nurse-led follow-up care or routine health education and follow-up (patients received Tai Chi exercises only for 6 months, n = 408) for 6-months. The Zung Self-Rating Depression and Anxiety Scale and Summary of Diabetes Self-Care Activities were used to evaluate anxiety, depression, and self-care activities, respectively. Before the start of follow-up care (BFC), knowledge regarding diabetes and its threat was ≤1.75, anxiety and depression scores were ≥52 each, and self-care activities were ≤37. After 6 months of follow-up care, patients in the patients received nurse-led follow-up care including educational programs for 6 months improved their knowledge regarding diabetes and its threat, anxiety, depression, and self-care activities as compared to their before the start of follow-up care conditions and patients in the RF and patients received Tai Chi exercises only for 6 months at after 6 months of follow-up care conditions (P < .001 for all). Chinese type 1 or 2 diabetes patients had worse physical and psychological conditions and less knowledge regarding diabetes and its threat. Nurse-led aftercare, including educational programs with Tai Chi exercises for 6 months, decreased anxiety and depression and improved knowledge regarding diabetes and its threat and self-care activities in diabetic patients (Level of Evidence: IV; Technical Efficacy: Stage 5).

Comparative analysis of biomechanical characteristics between the new Tai Chi elastic band exercise for opening and closing movement and elastic band resistance training for the reverse fly movement.

Background: The objective of this study was to compare and analyze the representative opening and closing movement of Tai Chi elastic band exercise with the reverse fly movement of elastic band resistance training. The aim was to explore the biomechanical differences between the two exercises and provide theoretical support for the application of Tai Chi elastic band exercise in health intervention. Methods: A total of 26 male participants were recruited and randomly divided into two groups in a 1:1 ratio. There were 13 participants in each Tai Chi elastic band exercise group and elastic band resistance training group. Both groups of participants used an elastic band to perform movement in the experiment. Experimental data were collected using the Vicon infrared motion capture system and Delsys surface EMG system. The AnyBody software was utilized to simulate the creation of a musculoskeletal model for both exercises. Result: The study found that the Tai Chi elastic band exercise group exhibited smaller horizontal abduction angle and flexion angle of the shoulder joint, as well as normalized RMS of the anterior deltoid and triceps brachii, compared to the elastic band resistance training group (P < 0.01); the Tai Chi elastic band exercise group exhibited greater elbow flexion angle, elbow flexion torque, and muscle strength of the infraspinatus, coracobrachialis, biceps brachii, brachialis and brachioradialis, compared to the elastic band resistance training group (P < 0.01); the Tai Chi elastic band exercise group exhibited smaller horizontal abduction angular velocity of the shoulder joint and a lower normalized RMS of the posterior deltoid, compared to the elastic band resistance training group (P < 0.05). Conclusion: (1) The opening and closing movement of Tai Chi elastic band exercise is characterized by a large elbow flexion angle, a small shoulder joint horizontal angle and flexion angle, and a slow and uniform speed of movement. The reverse fly movement of elastic band resistance training is characterized by a large horizontal abduction angle of the shoulder joint, a large flexion angle of the shoulder joint, a small flexion angle of the elbow joint, and a fast and uneven speed. (2) The opening and closing movement exerts a greater torque on the elbow flexion, while the reverse fly movement exerts a greater torque on the shoulder joint horizontal abduction and external rotation. (3) The opening and closing movement provide greater stimulation to the infraspinatus, coracobrachialis, and elbow flexor, while the reverse fly movement provides greater stimulation to the posterior deltoid, anterior deltoid, subscapularis, and elbow extensor. In summary, the variation in joint angle, joint angular velocity, and hand position could be the factor contributing to the differences in joint torque and muscle activity between the opening and closing movement of Tai Chi elastic band exercise and the reverse fly movement of elastic band resistance training.

Effects of different traditional Chinese exercise for knee osteoarthritis patients: A network meta-analysis of randomized controlled trials.

BACKGROUND: The most popular traditional Chinese exercise (TCE) techniques include Tai Chi, Yijinjing, Baduanjin, Wuqinxi, and Qigong. Exercise is advised as a primary treatment for knee osteoarthritis (KOA) according to clinical standards. According to several studies, TCE may be an effective way to help people with KOA manage their pain, stiffness, and physical function. Which TCE therapy is the most effective and whose particular usefulness is still debatable. The network meta-analysis (NMA) method is used in this study to evaluate and compare the effects of various TCE therapies on KOA patients. METHODS: We will search PubMed, Embase, Scopus, Cochrane Library, Web of Science, the China National Knowledge Infrastructure, Wanfang, the Chinese Scientific Journal Database (VIP), and the China Biology Medical Literature Database (CBM) for randomized controlled trials reporting TCE therapy for KOA patients published before October 25, 2023. The Stata 16.0 program will compare the effectiveness of various TCE therapies on KOA patients using conventional pairwise and NMA. RESULTS: The final 29 studies included 15 articles on Tai Chi, 7 articles on Baduanjin, 4 articles on Wuqinxi, and 3 articles on Yijinjing. Tai Chi was first for the effect sizes of VAS scores, WOMAC pain scores, and WOMAC available scores, while Baduanjin was ranked top for WOMAC stiffness scores. Research should continue to be conducted on the effect of Qigong on KOA intervention. CONCLUSIONS: This NMA will help determine the best TCE treatment for KOA and offer evidence-based bias for clinical decision-making.

The effect of different traditional Chinese exercises on bone mineral density in menopausal women: a systematic review and network meta-analysis.

Objective: To evaluate the optimal choice of traditional Chinese exercise (TCE) for improving bone mineral density in postmenopausal women through a network meta-analysis. Methods: The Chinese and English databases were searched, including China National Knowledge Infrastructure, Chongqing VIP, PubMed, Web of Science and Cochrane Library. The outcomes included BMD of lumbar L2-L4, femoral neck, ward triangle, and greater trochanter. Standardized mean differences (SMD) and 95% confidence intervals (CI) were used to assess the correlation between each group of interventions, and surface under the cumulative ranking (SUCRA) was used to rank the best interventions. Results: A total of 20 randomized controlled trials (RCTs) including 1933 subjects and six interventions: [Tai Chi (TC), Baduanjin (BDJ), Wuqinxi (WQX), Yijinjing (YJJ), TA (Tai chi plus calcium supplementation), BA (Baduanjin plus calcium supplementation)] and three control measures: [Calcium supplementation (CA), Aerobic exercise (AE), Not exercise intervention (NEI)] were analyzed. Regarding BMD of lumbar L2-L4: TC [SMD = 0.99 (0.62, 1.37)], BDJ [SMD = 2.12 (1.39, 2.85)], TA [SMD = 1.12(0.17, 2.07)], BA [SMD = 2.24 (1.16, 3.31)] were superior in increasing BMD of lumbar L2-L4 relative to NEI. Regarding BMD of femoral neck: TC [SMD = 1.24 (0.70, 1.78)], BA [SMD = 3.77 (1.98, 5.56)] were superior in increasing BMD of femoral neck relative to NEI. Regarding BMD of ward's triangle: TC [SMD = 1.63 (1.09, 2.17)] was superior in increasing BMD of ward's triangle relative to NEI. Regarding BMD of greater trochanter: TC [SMD = 0.98 (0.28, 1.68)] were superior in increasing BMD of greater trochanter relative to NEI. TC topped the SUCRA with BMD of lumbar L2-L4: 53.8, femoral neck: 74.9, ward's triangle: 86.9 and greater trochanter: 77.7. Conclusion: Four TCE (TC, BDJ, TA and BA) are all effective in partially improving BMD indicators in postmenopausal women, while TC was effective on all four BMD indicators, which seems to be recommended as the most suitable exercise modality for postmenopausal women. Systematic review registration: This research follows the PRISMA Network statement. The protocol for this study has been registered in the International Prospective Registry of Systematic Reviews (PROSPERO). CRD42023414944.

Long- and short-term effectiveness of traditional Chinese exercises in improving the overall physical capacity of patients with knee osteoarthritis: A systematic review and meta-analysis.

BACKGROUND: The increasing global popularity of traditional Chinese exercise (TCE) provides substantial evidence of its significant efficacy in treating knee osteoarthritis (KOA). To assess the impact of different types of TCE and varying exercise durations on KOA patients, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) on this topic. METHODS: Two investigators extensively searched four electronic databases (PubMed, Embase, Cochrane, and Web of Science) from their inception until December 16, 2023, to identify all relevant RCTs on the use of TCE for KOA treatment. The included studies were assessed for risk of bias using the Cochrane Collaboration Risk of Bias Tool (CCRBT), and data analysis was performed using Stata 15.0. RESULTS: A total of 20 RCTs, involving 1367 patients with KOA, met the inclusion criteria. Compared to the control group, TCE demonstrated significant improvement in three subscale scores of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) [Pain (SMD = -0.44; P = .0001); Stiffness (SMD = -0.35; P = .001); Physical function (SMD = -0.52; P = .0001)] and two subscale scores of the 36-item Short-Form (SF-36) [Physical score (WMD = 2.76; P = .001); Mental score (WMD = 2.49; P = .0001)] in KOA patients. Subgroup analysis showed that both long-term habitual exercise (over 12 weeks) and short-term exercise (within 12 weeks) were more effective than the control group in improving pain, joint stiffness, and physical function in KOA patients. Tai Chi, among the four TCE modalities analyzed, demonstrated improvements in all indicators. CONCLUSION: Based on the results of our meta-analysis, it can be concluded that both long-term and short-term TCE interventions are effective in alleviating the main symptoms of KOA and improving patients' physical function. However, due to limited methodological quality and inconsistent outcome measures in the included RCTs, further high-quality RCTs with larger sample sizes and longer-term interventions are necessary to validate our findings before TCE can be recommended as a treatment for KOA.

A trend of Tai Chi in osteoporosis research: A bibliometric analysis.

BACKGROUND: Tai chi has been used to treat different forms of osteoporosis and increase bone density without the use of pharmaceuticals. OBJECTIVE: The purpose of this study was to use bibliometric analysis to methodically examine trends and hotspots of tai chi treatment for osteoporosis in order to generate references for further investigation. METHODS: The articles on Tai Chi to treat osteoporosis was obtained from China National Knowledge Infrastructure (CNKI), Wan Fang, Web of Science (WOS) and PubMed between inception and November 8,2023. The annual publication volume, authors, institutions, and keywords, along with co-citation, clustering, and burst analysis, were analyzed using CiteSpace. RESULTS: Totally, 328 publications were included. The number of annual publications has been rising rapidly in recent years. Beijing University of Chinese Medicine and Shanghai University of Sport are two of the best universities for Tai Chi treatment in osteoporosis. This area of research is dominated by Zhou, Y; Yu, DH; Pence, BC and Qin,L. Core authors and core institutions having a relatively low level of collaboration indicates that there may be limited interaction and cooperation between these key players in the field. China had the highest volume of publications, followed by the United States. Furthermore, the majority of the study subjects and influence mechanism are the focus of current research in this field. CONCLUSION: Tai Chi in osteoporosis research field is in a stage of stable development. Universities and higher education institutions are the leading institutions in this field. China and the United States emerging as high productivity nations. The study of Tai Chi in osteoporosis not only focuses on the applicable population, effects and intervention methods, but also gradually shifts to the mechanism study such as "secretion of beneficial factors", "physical exercise load" and "oxidative stress status".

Tai Chi for balance and postural control in people with peripheral neuropathy: A scoping review.

BACKGROUND: Peripheral neuropathy can affect balance and increase fall risk. Tai Chi is known to activate neuromuscular systems and may help improve balance and postural control. We conducted a scoping review of clinical studies that evaluated the impact of Tai Chi on balance and related neurobiological outcomes among individuals with peripheral neuropathy. METHODS: We systematically searched three databases from inception to December 19, 2023 and identified 11 eligible clinical studies. We extracted trial information from each study and performed a qualitative study features analysis to summarize the clinical evidence and neurobiological mechanisms of Tai Chi in regulating balance among people with peripheral neuropathy. RESULTS: We found that among 508 participants with clinical peripheral neuropathy, Tai Chi significantly improved single leg stance, 6-min walk, timed up-and-go tests, and gait speed when measured pre- and post-exercise. However, the differences between Tai Chi and sham exercise control that involved active calisthenics and stretching exercises were not statistically significant. Studies that used quantitative sensory testing showed that Tai Chi was associated with significant increases in plantar vibration and tactile sensitivity. The effect of Tai Chi on postural control varied depending on plantar sensory loss status, and results on muscle strength remained mixed. Other neurobiological effects involve strengthening muscle performance and proprioception and consolidating cognitive awareness of walking strategy and practical behavioral techniques. CONCLUSIONS: The findings indicated that Tai Chi may enhance balance, postural control, and gait speed in patients with peripheral neuropathy, possibly through sensory restoration, although further research is needed to confirm this. Whether Tai Chi improves muscle strength or other gait health parameters is inconclusive. Rigorous randomized clinical trials should be conducted to determine the effect of Tai Chi on balance in this population by measuring functional balance and quantitative sensory outcomes.

Efficacy of Mindfulness Exercises for Primary Osteoporosis Pain and Balance: A Systematic Review and Network Meta-Analysis.

Mindfulness exercise has shown great benefits for patients with osteoporosis. However, there are various types of mindfulness exercises and no studies have compared their efficacy. The aim of this study was to compare the efficacy of mindfulness exercises on pain and balance in patients with primary osteoporosis. Articles published in 10 English and three Chinese language databases from January 1, 2003, to December 31, 2022, were systematically searched. Twenty-two studies (N = 1,603) of five types of mindfulness exercises (Pilates, Ba Duan Jin, Wu Qin Xi, Tai Chi, and Yi Jin Jing) were eligible for this meta-analysis. Evidence from this review indicated that all five of the mindfulness exercises included in this study effectively reduced pain and improved balance for patients with primary osteoporosis. Pilates had the highest value of surface under the cumulative ranking as the best intervention. Future studies could consider developing a standard guideline for mindfulness exercise to be incorporated into osteoporosis rehabilitation.

Development of a 12-Week Unsupervised Online Tai Chi Program for People With Hip and Knee Osteoarthritis: Mixed Methods Study.

BACKGROUND: Osteoarthritis is a leading contributor to global disability. While evidence supports the effectiveness of Tai Chi in improving symptoms for people with hip/knee osteoarthritis, access to in-person Tai Chi classes may be difficult for many people. An unsupervised online Tai Chi intervention for people with osteoarthritis can help overcome accessibility barriers. The Approach to Human-Centered, Evidence-Driven Adaptive Design (AHEAD) framework provides a practical guide for co-designing such an intervention. OBJECTIVE: This study aims to develop an unsupervised online Tai Chi program for people with hip/knee osteoarthritis. METHODS: An iterative process was conducted using the AHEAD framework. Initially, a panel of Tai Chi instructors and people with osteoarthritis was assembled. A literature review was conducted to inform the content of a survey (survey 1), which was completed by the panel and additional Australian Tai Chi instructors to identify Tai Chi movements for potential inclusion. Selection of Tai Chi movements was based on 3 criteria: those that were appropriate (for people with hip/knee osteoarthritis aged 45+ years), safe (to be performed at home unsupervised), and practical (to be delivered online using prerecorded videos). Movements that met these criteria were then ranked in a second survey (survey 2; using conjoint analysis methodology). Survey findings were discussed in a focus group, and the Tai Chi movements for program use were identified. A draft of the online Tai Chi program was developed, and a final survey (survey 3) was conducted with the panel to rate the appropriateness and safety of the proposed program. The final program was developed, and usability testing (think-aloud protocol) was conducted with people with knee osteoarthritis. RESULTS: The panel consisted of 10 Tai Chi instructors and 3 people with osteoarthritis. The literature review identified Yang Style 24 as a common and effective Tai Chi style used in hip/knee osteoarthritis studies. Surveys 1 (n=35) and 2 (n=27) produced a ranked list of 24 Tai Chi movements for potential inclusion. This list was refined and informed by a focus group, with 10 Tai Chi movements being selected for inclusion (known as the Yang Style 10 form). Survey 3 (n=13) found that 92% (n=12) of the panel members believed that the proposed draft Tai Chi program was appropriate and safe, resulting in its adoption. The final program was produced and hosted on a customized website, "My Joint Tai Chi," which was further refined based on user feedback (n=5). "My Joint Tai Chi" is currently being evaluated in a randomized controlled trial. CONCLUSIONS: This study demonstrates the use of the AHEAD framework to develop an unsupervised online Tai Chi intervention ("My Joint Tai Chi") for people with hip/knee osteoarthritis. This intervention is now being tested for effectiveness and safety in a randomized controlled trial.

Efficacy of Tai Chi exercise in patients with hypertension: systematic review and meta-analysis.

BACKGROUND: An estimated 1.28 billion adults aged 30-79 years worldwide have hypertension, most (two-thirds) living in low- and middle-income countries. Pharmachological approaches have side effect, prompting exploration of Non-pharmacological approaches, like Tai Chi. Although early evidence suggests a potential favourable benefit with Tai Chi, it remains unclear whether the method can significantly reduced SBP and DBP. We aimed to assess by a systematic review and meta-analysis the effectiveness of Tai Chi in alleviating SBP and DBP on hypertension patients. METHODS: Our study adhered to the PRISMA method and was registered in PROSPERO under the code CRD42024496192. The search was carried out in the PubMed, Web of Science, Embase, and the Cochrane Library databases in December 2023. Five randomized controlled trials were included (a total of 568 patients). Risk of bias was employed to assess the quality of individual studies, and a random-effects model was utilized to examine the overall effect. RESULTS: The results showed that Tai Chi, when compared to routine care, had a statistically significant impact on SBP ((MD = 5.49, 95 % CI: 3.44 to 7.54, p = 0.001), with a heterogeneity I2 = 54%. Tai Chi did not show a significant difference in terms of DBP when compared to standard care (MD =3.18, 95 % CI: 1.89 to -4.48, p = 0.31). The included trials exhibited small sample sizes, substantial heterogeneity. CONCLUSIONS: Tai Chi effectively lowers SBP levels in hypertension patients, however, did not show a statistically significant difference on DBP.

Effect of Tai Chi exercise on bone health and fall prevention in postmenopausal women: a meta-analysis.

BACKGROUND: The bone status of postmenopausal women is worsening. In fact, postmenopausal period is the high incidence stage of osteoporosis and falls. Notably, a recent study has pointed out that exercise can improve bone health in postmenopausal women. However, the effect of Tai Chi exercise on postmenopausal women is controversial. Therefore, a meta-analysis was designed to analyze the effect of Tai Chi exercise on bone health and fall prevention in postmenopausal women. METHODS: The researches on Tai Chi improving the bone health of postmenopausal women before August 31, 2023 were collected from Chinese and English databases, such as PubMed, Embase, and Web of Science, etc. The risk of bias of the included studies was assessed using the Cochrane risk-of-bias tool for randomized trials. Besides, R software 4.3.1 was employed to analyze the effect sizes in the meta-analysis to summarize the impact of Tai Chi on vertebral bone mineral density, serum calcium, clinical balance scores, the number of falls, total falls, and health status scores in postmenopausal women. RESULTS: There were 12 studies eventually included in this meta-analysis. A total of 1,272 postmenopausal women were involved, including 628 in the experimental group (intervention with Tai Chi exercise) and 644 in the control group (without any intervention). Briefly, postmenopausal women practicing Tai Chi presented a significant increase in vertebral bone density [standardized mean difference (SMD) = 0.37, 95% confidence interval (CI) (0.04-0.71), P = 0.03] and health status score [SMD = 0.25, 95% CI (0.01-0.49), P = 0.04]. In contrast, there were no significant differences for postmenopausal women between the two groups in terms of serum calcium [SMD = -0.01, 95% CI (-0.39, 0.36), P = 0.77], clinical balance [SMD = 0.17, 95% CI (-0.01, 0.46), P = 0.23], number of falls [SMD = -0.61, 95% CI (-1.24, 0.02), P = 0.06] and total falls [odds ratio = 0.35, 95% CI (0.11-1.12), P = 0.07]. CONCLUSION: Tai Chi exercise can improve the bone mineral density of postmenopausal women, thereby maintaining bone health. Hence, Tai Chi exercise is necessary to prevent osteoporosis.
