Abstract
This study investigated the effects of Tai Chi training on functionality, dynamic balance, kinesiophobia, and quality of life in athletes with Functional Ankle Instability (FAI). Forty-three athletes with FAI were randomly assigned to either a Tai Chi group (n = 21) or a control group (n = 22). The Tai Chi group followed a tailored exercise protocol addressing ankle instability through a three-phase progression, while the control group had no intervention but continued their usual activities. Measurements, including Cumberland Ankle Instability Tool (CAIT), Star Excursion Balance Test (SEBT), Tampa Scale for Kinesiophobia (TSK), Short Form-12 (SF-12), figure-8 hop test, and perceived treatment effect were assessed before and after the intervention. The Tai Chi group showed significant improvements in CAIT score and SEBT reach distance compared to the control group (p < 0.001). Tai Chi exercises also reduced TSK, improved figure-8 hop score, and enhanced the physical component of SF-12 (p < 0.005), with no significant effect on the mental component of SF-12 (p = 0.7). The findings imply that Tai Chi may be a valuable consideration for athletic trainers and sports medicine professionals working with athletes with FAI.

Abstract
The load and stress distribution on cartilage and meniscus of the knee joint in typical lower limb movements of Chen-style Tai Chi (TC) and deep squat (DS) were analyzed using finite element (FE) analysis. The loadings for this analysis consisted of muscle forces and ground reaction force (GRF), which were calculated through the inverse dynamic approach based on kinematics and force plate measurements obtained from motion capture experiments. Thirteen experienced practitioners performed four typical TC movements, namely, single whip (SW), brush knee and twist step (BKTS), stretch down (SD), and part the wild horse's mane (PWHM), which exhibit lower posture and greater lower limb force compared to other TC styles. The results indicated that TC required greater lower limb muscle strength than DS, resulting in greater knee joint forces. The stress on the medial cartilage in SW and BKTS fell within a range conductive to maintaining the balance between anabolism and catabolism of cartilage matrix. This was due to the fact that SW and BKTS reduce the medial to total tibiofemoral contact force ratios through knee abduction, which may effectively alleviate mild medial knee osteoarthritis (KOA). However, the greater medial contact force ratios observed in SD and PWHM resulted in great contact stresses that may aggravate the pain of patients with KOA. To mitigate these effects, practitioners should consider elevating their postures appropriately to reduce knee flexion angles, especially during the single-leg support phase. This adjustment can decrease the required muscle strength, load and stress on the knee joint.

Abstract
PURPOSE To investigate the connection between the clinical severity of chronic venous insufficiency (CVI) and the biomechanics of the calf muscle pump (CMP). MATERIAL AND METHODS Through a cross-sectional observational study, we analyzed women on the age range between 30 and 80 years with chronic venous insufficiency, stratified according to the clinical classification. Ninety-nine women were assessed and classified into groups with different levels of severity: C1 (n = 22); C2 (n = 22); C3 (n = 22); C4 (n = 22); C5 (n = 8); C6 (n = 3). The main purpose was to investigate the strength of the calf muscle pump through total work (TW) and peak torque (PT), and the range of motion (ROM) of the ankle joint. For a secondary analysis, the fatigue index was assessed. All results were run through the Humac®/NORMT isokinetic dynamometer to obtain the data. RESULTS Our findings pointed out that as the clinical severity of CVI increases, there is a reduction on the PT, the TW, the maximum active ROM and the ROM at 120°/sec. As severity increased, there was a reduction of 24Nm in the TW at 30°/sec.and a reduction of 3Nm in the PT at 30°/sec. OUTCOMES When increased, clinical severity of CVI may trigger downgrading in the strength of the CMP and the ROM in the ankle. These findings are of relevance to the clinician, since through these findings, individuals with venous insufficiency may be treated more precisely for each classification.

Trials 2023; 24:241. [PMID: 37386473 DOI: 10.1186/s13063-023-07146-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2021] [Accepted: 02/08/2023] [Indexed: 07/01/2023] Open
Abstract
BACKGROUND Parkinson's disease (PD) is associated with changes in gait and posture, which increases the rate of falls and injuries in this population. Tai Chi (TC) training enhances the movement capacity of patients with PD. However, the understanding of the effect of TC training on gait and postural stability in PD is lacking. This study aims to examine the effect of biomechanical-based TC training on dynamic postural stability and its relationship with walking performance. METHODS/DESIGN A single-blind, randomized control trial of 40 individuals with early-stage PD was conducted (Hoehn and Yahr stages 1 to 3). Patients with PD will be randomly assigned to either the TC or control group. The TC group will participate in a biomechanical-based TC training program that is formed based on the movement analysis of TC and will be practiced thrice a week for 12 weeks. The control group will be required to engage in at least 60 min of regular physical activity (PA) on their own for three times per week for 12 weeks. The primary and secondary outcomes will be assessed at baseline and at 6 and 12 weeks after commencing the study protocol. The primary outcome measures will include dynamic postural stability indicated by the center of mass and center of pressure separation distance and clearance distance of the heel and toe measured during fixed-obstacle crossing. The secondary measures are gait speed, cadence, step length during level surface walking (simple task), and fixed-obstacle crossing (challenging task). The Unified Parkinson's Disease Rating Scale, single leg-stance test with eyes open and closed, and three cognitive scores (Stroop Test, Trail Making Test Part B, and the Wisconsin Card Sorting Test) were also employed. DISCUSSION This protocol could lead to the development of a biomechanics TC training program for the improvement of gait and postural stability among individuals with PD. The program could enhance the understanding of the effect of TC training on gait and postural stability and could help improve or preserve the postural stability, self-confidence, and active participation in social activities of the participants, thus enhancing their overall quality of life. TRIAL REGISTRATION ClinicalTrials.gov NCT04644367. Registered on 25 November 2020.

Effects of 12 weeks of Tai Chi on neuromuscular responses and postural control in elderly patients with sarcopenia: a randomized controlled trial. Front Neurol 2023; 14:1167957. [PMID: 37188307 PMCID: PMC10176447 DOI: 10.3389/fneur.2023.1167957] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Accepted: 04/06/2023] [Indexed: 05/17/2023] Open
Abstract
Objective To explore the effect of 12 weeks of Tai Chi on neuromuscular responses and postural control in elderly patients with sarcopenia. Methods One hundred and twenty-four elderly patients with sarcopenia from ZheJiang Hospital and surrounding communities were selected, however, 64 were later disqualified. Sixty elderly patients with sarcopenia were randomly assigned to the Tai Chi group (n = 30) and the control group (n = 30). Both groups received 45-min health education sessions once every 2 weeks for 12 weeks, and the Tai Chi group engaged in 40-min simplified eight-style Tai Chi exercise sessions 3 times per week for 12 weeks. Two assessors who had received professional training and were unaware of the intervention allocation assessed the subjects within 3 days prior to the intervention and within 3 days after completion of the intervention. They chose the unstable platform provided by the dynamic stability test module in ProKin 254 to evaluate the patient's postural control ability. Meanwhile, surface EMG was utilized to assess the neuromuscular response during this period. Results After 12 weeks of intervention, the Tai Chi group showed a significant decrease in neuromuscular response times of the rectus femoris, semitendinosus, anterior tibialis, and gastrocnemius and overall stability index (OSI) compared to before the intervention (p < 0.05), while there was no significant difference in the control group for these indicators before and after intervention (p > 0.05). In addition, these indicators in the Tai Chi group were significantly lower than those in the control group (p < 0.05). The changes in neuromuscular response times of the rectus femoris, semitendinosus, anterior tibialis, and gastrocnemius were positively correlated with the changes in OSI (p < 0.05) in the Tai Chi group, but there were no significant correlations between changes in neuromuscular response times of the aforementioned muscles and changes in OSI in the control group (p < 0.05). Conclusion Twelve-weeks of Tai Chi exercise can improve the neuromuscular response of the lower extremities in elderly patients with sarcopenia, shorten their neuromuscular response time when balance is endangered, enhance their dynamic posture control ability, and ultimately reduce the risk of falls.

Abstract
This study examined the maximum joint angles and moments, and electromyography (EMG) activity of the lower limbs in an experienced Tai Chi (TC) practitioner in performing four dynamic (Repulse Monkey, Wave-hand in Clouds, Brush Knee Twist Step, and Lateral Forward Step) and three static TC movements (Starting Form, Hero Touch Sky, and Push Hand Back) and compared them with the measures from walking. Integrated EMG (iEMG) and peak EMG of the rectus femoris, adductor longus, tibialis anterior, semitendinosus, erector spinae, gluteus medius, tensor fasciae latae, medial and lateral gastrocnemius muscles were analyzed. One-way analysis of variance showed that compared with walking, TC presented 1) significantly larger hip flexion (71.4° vs. 42.2°) and abduction angles (11.9° vs. 5.3°), smaller knee flexion (45.2° vs. 71.1°) and abduction angles (13.0° vs. 27.7°), larger ankle dorsiflexion (41.4° vs. 11.3°) and abduction angles (8.8° vs. 7.2°); 2) hip flexion moment and knee flexion and abduction moment were significantly larger. Ankle dorsiflexion moment were significantly smaller, whereas ankle abduction moment was significantly larger in two TC movements; and 3) the EMG activity of the muscles in TC varied from 10% to 610% of walking. The knee extensors, hip adductors and abductors had significantly higher peak EMG (430% ± 40%, 240% ± 30%, and 320% ± 90%) and iEMG values (610% ± 30%, 311% ± 30%, and 1.4% ± 20%), respectively. The findings suggested that these TC movements could be a good option for the improvement of muscle strength and range of motion of the lower limbs.

Abstract
Background: It is known that lower-limb muscle strength is easily maintained in elderly people who practice Tai Chi, although it is necessary to maintain lower-limb muscle strength even as age increases in order to prevent falls. However, the effect of long-term Tai Chi practice and age on lower-limb ability is unclear in middle-aged and elderly people. This research was designed to compare lower-extremity parameters during a countermovement jump between middle-aged and elderly individuals who frequently practice Tai Chi Chuan and individuals in the general population who constituted the healthy group. Methods: There were four groups, and each group included 12 participants. Ten Vicon motion system infrared cameras and two Kistler force plates were used. The data were standardized and analysed using independent-measure two-way ANOVA. Results: The statistical results showed that there was no interaction between the age factor and exercise type factor. The statistics of age factor also showed that age may decrease the jump height (36.36%), peak knee power (24.74%) and peak ankle power (21%) during the take-off phase. In the exercise type factor, long-term Tai Chi training significantly increased the jump height (60%), peak knee moment (19.80%), peak ankle moment (8.06%), peak hip power (29.80%), peak knee power (31.23%) and peak ankle power (16.88%) during the take-off phase. Conclusion: This study shows that long-term Tai Chi training can slow ageing-related functional decline. According to the results of this study, middle-aged and elderly people are encouraged to regularly perform Tai Chi exercises to increase the strength of various muscle groups in the lower limbs and slow the lower-limb muscle changes caused by ageing.

The effectiveness of traditional Chinese medicine-based exercise on physical performance, balance and muscle strength among older adults: a systematic review with meta-analysis. Aging Clin Exp Res 2022; 34:725-740.

Abstract
BACKGROUND Traditional Chinese medicine (TCM) based exercises have been widely used in the prevention and treatment of balance, cardiopulmonary, and other related diseases in older adults. However, there seems to be no consensus on the improvement and comparison of physical performance, balance, and muscle strength in the elderly population. OBJECTIVES To systematically examine the impact of different TCM-based exercises on physical performance, balance, and muscle strength outcomes in the elderly. METHODS We searched PubMed, EMBASE, Scopus, and Cochrane Center, CNKI and Wan Fang between their date of inception and March 2021. This meta-analysis was performed using RevMan5.3 software. Only randomized controlled trials (RCT) or controlled clinical trials (CCT) were considered in TCM-based exercises (Tai Chi, Ba Duan Jin, Qigong). The overall mean difference (MD) or standardized mean difference (SMD), and its 95% confidence interval (CI) were calculated. MAIN RESULTS A total of 27 studies with 2580 older adults met the inclusion criteria. The pooled analysis indicated that Tai Chi could be more effective in Times up and go (TUG) (MD = - 2.62, 95% CI - 4.00 to - 1.24, P = 0.0002), 5 times sit-stand (MD = - 1.89; 95%CI - 3.38 to - 0.40; P = 0.01), and handgrip strength outcomes (SMD = 0.69; 95%CI 0.52-0.86; P < 0.0001) compared to Ba Duan Jin and Qigong. The older adults performing Qigong could have a better benefit in Single-bed balance (SLB) with eyes closed compared to Tai Chi and Ba Duan Jin (MD = 3.42; 95%CI 1.55 to 5.29; P = 0.0003). Tai Chi also had benefits in terms of balance outcomes compared to those in the control group: Berg Balance scale (BBS) (MD = 1.41; 95% CI 0.03-2.85; P = 0.05), Functional reach test (FRT) (MD = 1.57; 95%CI 1.22-1.93; P < 0.0001). The Tai Chi study meta-analysis demonstrated significant effects on lower limb strength: knee extension (SMD = 0.56; 95%CI 0.26-0.86; P = 0.0003), ankle dorsiflexion (SMD = 0.67; 95%CI 0.02-1.31; P = 0.04) compared to the controls. CONCLUSION This systematic review reveals that TCM-based exercises can effectively improve physical performance outcomes, balance outcomes, and muscle strength in the elderly population. While there is limited evidence on the efficacy of other TCM-based lifestyle interventions, more high-quality clinical trials on this topic are warranted.

Abstract
BackgroundReactive balance is the last line of defense to prevent a fall when the body loses stability, and beneficial effects of various exercise-based interventions on reactive balance in older adults have been reported. However, their pooled evidence on the relative effects has yet to be described.ObjectiveTo review and evaluate the comparative effectiveness of various exercise-based interventions on reactive balance in older adults.MethodsNine electronic databases and reference lists were searched from inception to August 2021. Eligibility criteria according to PICOS criteria were as follows: (1) population: older adults with the mean age of 65 years or above; (2) intervention and comparison: at least two distinct exercise interventions or one exercise intervention with a no-exercise controlled intervention (NE) compared in each trial; (3) outcome: at least one measure of reactive balance; (4) study: randomized controlled trial. The main network meta-analysis was performed on data from the entire older adult population, involving all clinical conditions as well as healthy older adults. Subgroup analyses stratified by characteristics of participants (healthy only) and reactive balance outcomes (simulated slip or trip while walking, simulated forward falls, being pushed or pulled, and movable platform) were also conducted.ResultsThirty-nine RCTs (n = 1388) investigating 17 different types of exercise interventions were included in the network meta-analysis. Reactive balance training as a single intervention presented the highest probability (surface under the cumulative ranking (SUCRA) score) of being the best intervention for improving reactive balance and the greatest relative effects vs. NE in the entire sample involving all clinical conditions [SUCRA = 0.9; mean difference (95% Credible Interval): 2.7 (1.0 to 4.3)]. The results were not affected by characteristics of participants (i.e., healthy older adults only) or reactive balance outcomes.Summary/ConclusionThe findings from the NMA suggest that a task-specific reactive balance exercise could be the optimal intervention for improving reactive balance in older adults, and power training can be considered as a secondary training exercise.

Meta-Analysis of Elderly Lower Body Strength: Different Effects of Tai Chi Exercise on the Knee Joint-Related Muscle Groups. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2021:8628182. [PMID: 34976101 PMCID: PMC8716219 DOI: 10.1155/2021/8628182] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/20/2021] [Accepted: 11/09/2021] [Indexed: 11/18/2022]
Abstract
OBJECTIVE To determine whether lower body strength such as keen extension and flexion strength may be improved by Tai Chi exercise in older adults from the perspective of evidence-based medicine. METHODS Databases of PubMed, Embase, and Cochrane Library were searched up to July 1, 2021. Randomized clinical trials are adopted to compare Tai Chi exercise with sedentary behavior or other low intensity exercise in terms of influence on lower body strength rehabilitation, especially keen extension and flexion strength in people aged over 60. A meta-analysis was performed to discuss outcomes of lower body strength, knee muscle strength, and knee extension/flexion strength. RESULTS A total of 25 randomized trials involving 1995 participants fulfilled the inclusion criteria. (1) Tai Chi exercise significantly improved elderly lower body strength (-0.54, [-0.81, -0.28], p < 0.00001, I 2 = 74%), but there was no differential improvement in the strength of the knee joints (0.10, [-0.02, 0.23], p=0.11, I 2 = 34%). (2) Elderly individual lower body strength declined with age, while this trend was suppressed by Tai Chi exercise (-0.35, [0.14, 0.56], p=0.001, I 2 = 70%). (3) Although Tai Chi exercise did no significantly improve the large muscle group of knee joint extensor like quadriceps femoris (3.15, [-0.69, 6.99], p=0.24, I 2 = 26%), it showed marked enhancement to the strength of deep small muscle group of knee joint flexor (10.25, [6.90, 13.61], p < 0.00001, I 2 = 0%). The heterogeneity might be caused by distinguished measurements of muscle strength. Therefore, Tai Chi exercise specifically enhanced some certain muscle strength of knee joints and improved muscle fitness rehabilitation as well as function activity for elderly. CONCLUSIONS In this RCT meta-analysis, Tai Chi exercise has positive effects on lower body strength of elderly. Although no obvious improvement on the knee extensor is observed, it may be used as a rehabilitation treatment for training stable deep muscle groups to improve the knee flexion strength significantly.

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

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

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

Abstract
Sarcopenia is an age-related loss of skeletal muscle mass caused by many cellular mechanisms and also by lifestyle factors such as low daily physical activity. In addition, it has been shown that sarcopenia may be associated with inflammation and cognitive impairment in old age. Regular exercise is key in reducing inflammation and preventing sarcopenia and diseases related to cognitive impairment. The study was designed to assess the impact of exercise training on circulating apoptotic and inflammatory markers of sarcopenia in older adults. Eighty older adults aged 70.5 ± 5.8 years were randomized to the physically active group who participated in a 10-month Tai-Chi training session (TC, n = 40) and the control group who participated in health education sessions (HE, n = 40). Tai-Chi training caused a significant decrease in fat mass (FM) by 3.02 ± 3.99%, but an increase in appendicular skeletal muscle mass index (ASMI) by 1.76 ± 3.17% and gait speed by 9.07 ± 11.45%. Tai-Chi training elevated the plasma levels of C-reactive protein (CRP), tumor necrosis factor (TNFα), and tumor necrosis receptor factor II (TNFRII), and decreased caspases 8 and 9. Despite the increase in TNFα, apoptosis was not initiated, i.e., the cell-free DNA level did not change in the TC group. The study demonstrated that Tai-Chi training significantly reduced the symptoms of sarcopenia through the changes in body composition and physical performance, and improvements in cytokine-related mechanisms of apoptosis.

Abstract
Objectives This systematic review aims to summarize the existing literature on Tai Chi randomized controlled trials (RCTs) and recommend Tai Chi exercise prescriptions for different diseases and populations. Methods A systematic search for Tai Chi RCTs was conducted in five electronic databases (PubMed, Cochrane Library, EMBASE, EBSCO, and Web of Science) from their inception to December 2019. SPSS 20.0 software and Microsoft Excel 2019 were used to analyze the data, and the risk of bias tool in the RevMan 5.3.5 software was used to evaluate the methodological quality of RCTs. Results A total of 139 articles were identified, including diseased populations (95, 68.3%) and healthy populations (44, 31.7%). The diseased populations included the following 10 disease types: musculoskeletal system or connective tissue diseases (34.7%), circulatory system diseases (23.2%), mental and behavioral disorders (12.6%), nervous system diseases (11.6%), respiratory system diseases (6.3%), endocrine, nutritional or metabolic diseases (5.3%), neoplasms (3.2%), injury, poisoning and certain other consequences of external causes (1.1%), genitourinary system diseases (1.1%), and diseases of the eye and adnexa (1.1%). Tai Chi exercise prescription was generally classified as moderate intensity. The most commonly applied Tai Chi style was Yang style (92, 66.2%), and the most frequently specified Tai Chi form was simplified 24-form Tai Chi (43, 30.9%). 12 weeks and 24 weeks, 2-3 times a week, and 60 min each time was the most commonly used cycle, frequency, and time of exercise in Tai Chi exercise prescriptions. Conclusions We recommend the more commonly used Tai Chi exercise prescriptions for different diseases and populations based on clinical evidence of Tai Chi. Further clinical research on Tai Chi should be combined with principles of exercise prescription to conduct large-sample epidemiological studies and long-term prospective follow-up studies to provide more substantive clinical evidence for Tai Chi exercise prescriptions.

Abstract
Objective To investigate the impact of Tai Chi training on muscle strength, physical endurance, postural balance and flexibility, as measured by tests commonly used in health-related fitness or competitive sports contexts. Design Systematic review and meta-analysis. Data sources The following databases were searched up to 31 July 2020: CINAHL, Cochrane Library, MEDLINE via PubMed and SPORTDiscus. Eligibility criteria for studies Inclusion: (1) Randomised controlled trials published in German or English; (2) Tai Chi used as an intervention to improve physical performance; (3) Test methods commonly used in health-related fitness or competitive sports and (4) Participants aged ≥16 years (irrespective of health status). Exclusion: (1) Studies not focusing on Tai Chi or including Tai Chi mixed with other interventions and (2) Modified or less than eight Tai Chi movements. Results Out of 3817 records, 31 studies were included in the review, 21 of them in the meta-analysis. Significant improvements in handgrip strength (2.34 kg, 95% CI 1.53 to 3.14), walking distance during 6 min (43.37 m, 95% CI 29.12 to 57.63), standing time in single-leg-stance with open eyes (6.41 s, 95% CI 4.58 to 8.24) and thoracolumbar spine flexibility (2.33 cm, 95% CI 0.11 to 4.55) were observed. Conclusion Tai Chi training seems to moderately improve physical fitness when evaluated by tests used in health-related fitness or competitive sports. Moreover, thoracolumbar spine flexibility seems to be a factor in the improvement of postural balance. Further research is needed, including younger healthy participants performing a widely used, standardised form (eg, Peking-style routine) with high-intensity movements (eg, use of lower stances).

Tai Chi training's effect on lower extremity muscle co-contraction during single- and dual-task gait: Cross-sectional and randomized trial studies. PLoS One 2021; 16:e0242963.

Abstract
BACKGROUND Tai Chi (TC) mind-body exercise has been shown to reduce falls and improve balance and gait, however, few studies have evaluated the role of lower extremity muscle activation patterns in the observed benefits of TC on mobility. PURPOSE To perform an exploratory analysis of the association between TC training and levels of lower extremity muscle co-contraction in healthy adults during walking under single-task (ST) and cognitive dual-task (DT) conditions. METHODS Surface electromyography of the anterior tibialis and lateral gastrocnemius muscles was recorded during 90 sec trials of overground ST (walking normally) and DT (walking with verbalized serial subtractions) walking. A mean co-contraction index (CCI), across all strides, was calculated based on the percentage of total muscle activity when antagonist muscles were simultaneously activated. A hybrid study design investigated long-term effects of TC via a cross-sectional comparison of 27 TC experts and 60 age-matched TC-naïve older adults. A longitudinal comparison assessed the shorter-term effects of TC; TC-naïve participants were randomly allocated to either 6 months of TC training or to usual care. RESULTS Across all participants at baseline, greater CCI was correlated with slower gait speed under DT (β(95% CI) = -26.1(-48.6, -3.7)) but not ST (β(95% CI) = -15.4(-38.2, 7.4)) walking. Linear models adjusting for age, gender, BMI and other factors that differed at baseline indicated that TC experts exhibited lower CCI compared to TC naives under DT, but not ST conditions (ST: mean difference (95% CI) = -7.1(-15.2, 0.97); DT: mean difference (95% CI) = -10.1(-18.1, -2.4)). No differences were observed in CCI for TC-naive adults randomly assigned to 6 months of TC vs. usual care. CONCLUSION Lower extremity muscle co-contraction may play a role in the observed benefit of longer-term TC training on gait and postural control. Longer-duration and adequately powered randomized trials are needed to evaluate the effect of TC on neuromuscular coordination and its impact on postural control. TRIAL REGISTRATION The randomized trial component of this study was registered at ClinicalTrials.gov (NCT01340365).

Abstract
Background HIIT has recently been widely used for health promotion in healthy people and patients with chronic diseases. Exercise can help SUD reduce drug cravings, enhance mental health and return to normal life. However, whether HIIT can bring better physical rehabilitation benefits to individuals with SUD than MICT is unclear. The study aimed to compare the effects of HIIT versus MICT on the physical fitness of individuals with SUD. Methods One hundred twenty individuals with amphetamine-type stimulant dependence voluntarily participated in this study. They were randomly assigned to the HIIT group and MICT group. Both groups received training three times a week. The intervention lasted from January 2019 to December 2019. Physical fitness was assessed at the baseline, 3 months, 6 months, 9 months and 12 months, including blood pressure (BP), vital capacity(VC), hand grip, push-up, sit-and-reach, one-leg standing with eyes closed and choice reaction time. The craving level was assessed using the Visual Analog Scale at baseline, 6 months and 12 months to see any change along with the improvement in physical fitness. Two-way repeated measures ANOVA was applied to analyse the differences in change by group (HIIT and MICT) and time (baseline, 3 months, 6 months, 9 months and 12 months). Results The within-group factor displayed significant changes in the HIIT and MICT groups in terms of systolic BP (F (4,336) = 12.799, P < 0.001,η2 = 0.204), diastolic BP (F(4,336) = 9.495, P < 0.001, η2 = 0.16), VC (F(4,336) = 18.121, P < 0.001, η2 = 0.177), hand grip (F(4,336) = 34.815, P < 0.001, η2 = 0.293), sit-and-reach (F(4,336) = 13.871, P < 0.001, η2 = 0.142), push-up (F(4,336) = 28.805, P < 0.001, η2 = 0.255), one-leg standing with eyes closed (F(4,336) = 14.495, P < 0.001, η2 = 0.156) and choice reaction time (F(4,336) = 20.603, P < 0.001, η2 = 0.197). The craving level decreased after 12 months of intervention in both groups (F(2,168) = 11.25, P < 0.001, η2 = 0.118), but no significant differences in physical fitness and craving level were found in between groups and the interactions of group × time. Conclusions After 12 months of intervention, physical fitness improved while craving level decreased in the two groups. These findings suggest that both HIIT and MICT have positive effects on individuals with SUD in terms of physical fitness.

Abstract
BACKGROUND AND PURPOSE Tai Ji Quan (TJQ) practice has been recommended for reducing falls in older adults, but a gap exists in our understanding of the neuromuscular mechanisms underlying TJQ practice benefits. This study aims to quantify and validate neuromuscular mechanisms underlying TJQ practice benefits in older adults. MATERIALS AND METHODS This review and analysis followed the PRISMA framework. All meta-analyses were performed in R. RESULTS For healthy older adults, TJQ practice was found to decrease muscle onset latency. Higher leg muscle activations were found during TJQ gait in comparison to normal gait. A significant interaction between TJQ practice time and age of the cohort was observed in muscle onset latency. For adults with pre-existing health conditions, TJQ practice has similar neuromuscular benefits as conventional rehabilitation methods. CONCLUSION Neuromuscular function improvements associated with TJQ practice provide a mechanism for reducing falls in older adults with and without pre-existing health conditions.

Abstract
Tai Chi Chuan (TCC) is a promising intervention against age-related decline. Though previous studies have shown benefits in motoric and cognitive domains, it is unclear how these effects are functionally related. Therefore, a randomized controlled trial was conducted in an aging population (53-85). Two measures of motor functioning - motor speed and functional balance - and three cognitive control measures - shifting, updating and inhibition - were included. The TCC condition consisted of an online 10 week 20 lessons video program of increasing level and control condition of educational videos of similar length and frequency. All analyses were done with Bayesian statistics. Counter to expectation no differences were found in cognition between TCC and control pre-to-posttest. However, there was extreme evidence for TCC benefits on functional balance and moderate evidence for increased motoric speed. After weighing the evidence and limitations of the intervention we conclude that TCC does not enhance cognitive control.

Abstract
BACKGROUND This study compared the effect of Tai Chi with the same frequency and different session duration on the bone mineral density (BMD) of older women. METHODS Healthy older women aged 55-70 years were randomly divided into the short-time group (N.=17), long-time group (N.=18), and control group (N.=17). The BMD of L<inf>2-4</inf> and the proximal femur were measured at baseline and after 48 weeks of intervention. RESULTS From 0 to 48 weeks, the respective BMD values of L<inf>2-4</inf> and the femoral neck in the short-time and long-time groups increased by 8.8% and 7.5% (P<0.01) and 8.8% and 12.7% (P<0.01), while the BMD of the greater trochanter in the control group decreased by 3.0% (P<0.05). After 48 weeks, the BMD of L<inf>2-4</inf> and the femoral neck was greater in the short-time and long-time groups than the control group (P<0.001). CONCLUSIONS Tai Chi for 30 or 60 minutes five times weekly for 48 weeks improves the BMD of L<inf>2-4</inf> and the femoral neck in older women but does not affect the BMD of the greater trochanter and Ward's triangle. Increasing the exercise duration does not increase the effect of Tai Chi on BMD.

Abstract
This study sought to compare the biomechanical parameters of the lower extremities during a countermovement jump in elderly people who are engaged in frequent practice of tai chi chuan (TCG) and in the general population of healthy elderly people (HG). Each group included 12 participants. Ten Vicon Motion System infrared cameras and two Kistler force plates were employed for measurement. The jump height, duration, centre of mass (COM) displacement, joint ROM, and upward velocity were analysed in this study. Motion analysis and force platform data were combined to calculate joint moments and powers during the takeoff phase. The data were analysed using independent sample t-tests. The results showed that the tai chi chuan practitioner group (0.13 m) achieved 44% higher jump heights (p < 0.05). The COM displacement during squatting was lower in the TCG (0.25 m) than in the HG (0.19 m) (p < 0.05). The knee and ankle ROMs of the TCG were higher than those of the HG (p < 0.05). Peak knee moment 23% and peak knee power 32% higher in TCG compared to the HG (p < 0.05), suggesting that frequent practice of tai chi chuan may slow the rate of knee degeneration.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease with increasing morbidity and mortality that cause huge social and economic loss. Although recommended by guidelines, pulmonary rehabilitation has not been widely applied in clinics because of its inherent limitations. Free from restrictions of specific training venues and equipment, Tai Chi, as a kind of pulmonary rehabilitation, has been used to cure the COPD, yet the efficacy and safety of Tai Chi remains to be assessed. In this study, we aim to draw up a protocol for systematic review to evaluate the efficacy and safety of Tai Chi for COPD. METHODS We will search the following electronic databases from inception to December 31, 2018: PubMed, Web of Science, Medline, Cochrane Central Register of Controlled Trials, Springer, EMBASE, the China National Knowledge Infrastructure Database, Wan Fang Database, the Chinese Scientific Journal Database, and Chinese Biomedical Literature Database. Clinical trial registrations, potential gray literatures, relevant conference abstracts and reference list of identified studies will also be searched. The literature selection, data extraction, and quality assessment will be completed by 2 independent authors. Either the fixed-effects or random-effects model will be used for data synthesis based on the heterogeneity test. Changes in lung function will be evaluated as the primary outcome. Symptom assessment, quality of life (SGRQ), medication usage, exacerbations, and adverse events will be assessed as the secondary outcomes. The RevMan V.5.3.5 will be used for Meta-analysis. RESULTS This study will provide a synthesis of current evidence of Tai Chi for COPD from several aspects, such as lung function, SGRQ, medication usage, exacerbations, and adverse events. CONCLUSION The conclusion of our study will provide updated evidence to judge whether Tai Chi is an effective solution to COPD patients. PROSPERO REGISTRATION NUMBER PROSPERO CRD42019122791.

Effects of Tai Chi on partial anterior cruciate ligament injury: A single-blind, randomized-controlled trial. Turk J Phys Med Rehabil 2019; 65:160-168. [PMID: 31453557 DOI: 10.5606/tftrd.2019.2798] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2018] [Accepted: 06/09/2018] [Indexed: 11/21/2022] Open
Abstract
Objectives This study aims to investigate the effects of Tai Chi (TC) exercises on muscle strength, pain, proprioception, and knee function in patients with partial anterior cruciate ligament (ACL) injuries. Patients and methods Between March 2017 and January 2018, a total of 58 patients with partial ACL injuries (30 male, 28 female; mean age 25.5±6.4; range, 18 to 36 years) were included in the study. The patients were randomly divided into two groups: TC group (n=29) and control group (n=29). For both groups, an activity modification approach was applied. The TC group participated in a 24-week TC exercise program, while no exercise or home-based program was administered to the control group. Isokinetic knee extension and flexion muscle strengths were evaluated at angular velocities of 60°/sec and 180°/sec. The visual analog scale (VAS), isokinetic system, Lysholm Knee Scale (LKS), and International Knee Documentation Committee 2000 (IKDC-2000) were used for the evaluation of pain, proprioception, and knee function, respectively. Results Significant changes were found in the TC group for the knee extensor muscle strength measured at an angular velocity of 60°/sec (p=0.012) and 180°/sec (p=0.011), VAS pain (p=0.005), and proprioception (measured with isokinetic device) (p<0.001). While knee extensor muscle strength, pain, proprioception, LKS, and IKDC-2000 scores improved in the TC group, improvements were recorded only for LKS and IKDC-2000 scores in the control group. Conclusion Based on these results, we conclude that TC exercises can yield positive outcomes on the knee extensor muscle strength, pain, proprioception and knee function in patients with partial ACL injuries. Hence, TC exercises can be used as a novel method by researchers and clinicians in the treatment of partial ACL injuries.

Abstract
BACKGROUND A variety of physical interventions have been used to improve reactive balance in older adults. PURPOSE To summarize the effectiveness of active treatment approaches to improve reactive postural responses in community-dwelling older adults. DESIGN Systematic review guided by PRISMA guidelines. STUDY SELECTION A literature search included the databases PubMed, OVID, CINAHL, ClinicalTrials.gov, OTseeker, and PEDro up to December 2017. Randomized controlled trials that evaluated quantitative measures of reactive postural responses in healthy adults following participation in an active physical training program were included. DATA SYNTHESIS Of 4,481 studies initially identified, 11 randomized controlled trials covering 313 participants were selected for analysis. Study designs were heterogeneous, preventing a quantitative analysis. Nine of the 11 studies reported improvements in reactive postural responses. CONCLUSIONS Several clinically feasible training methods have the potential to improve reactive postural responses in older adults; however, conclusions on the efficacy of treatment methods are limited because of numerous methodological issues and heterogeneity in outcomes and intervention procedures.

Abstract
This study was to investigate the effects of Tai Chi (TC) and whole-body vibration (WBV) exercise in sarcopenic men in advanced old age. Ninety sarcopenic men (mean age 88.6 years; age range 85-101 years) were divided into three groups: TC group, WBV group, and control (CON) group. Patients in the two treatment groups received 8 weeks of training in either TC or WBV, while the control group received reminders not to change their level of physical exercise or lifestyle. Patients in all groups also received health information related to sarcopenia. Muscle mass, muscle strength, and physical performance [balance, gait speed, timed-up-and-go test (TUGT), and five-times-sit-to-stand test (FTSST)] were analyzed and compared among the three groups. Finally, seventy-nine subjects completed the study (TC n = 24; WBV n = 28; and CON 27). Muscle strength was significantly increased in the TC and WBV groups compared to the control group (P < 0.01). Following 8 weeks of exercise, improvements were observed in all physical performance tests for the TC and WBV groups (P < 0.05). The improvement in balance was greater in the TC group than the WBV group. Time × Group effects revealed significant improvements in muscle strength in the lower extremities (P < 0.05) and physical performance (P < 0.01) in both the TC and WBV groups. Changes in muscle mass, as measured by dual-energy X-ray absorptiometry, did not significantly differ between groups. These findings indicate that TC and WBV are effective treatments for improving muscle strength and physical performance in sarcopenic men in advanced old age.

Abstract
BACKGROUND AND OBJECTIVE 24-form Tai Chi is a traditional exercise popular among old people in China, but it has some complex movements beyond of capabilities of patients with COPD. This study was to modify and simplify 24-form Tai Chi and evaluate effects of the modified Tai Chi on lung function, exercise capacity, dyspnea symptom and health status in patients with COPD. METHODS A two-step procedure was applied: an initial qualitative research module consisting of focus group discussion, expert consultation and patient interviews was conducted to simplified and modified 24-form Tai Chi for patients with COPD. Then, a randomized controlled trial consisting of 60 patients with II to IV COPD was conducted to evaluate effects of the modified Tai Chi on lung function (FEV1%), exercise capacity (Six minutes walking distance,6MWD), dyspnea symptom (Modified Medical Research Council Scale, mMRC) and health status (COPD Assessment Test, CAT). All measures were obtained at baseline, 3-month follow-up and 9-month follow-up. RESULTS A new simpler 6-form Tai Chi that combining characteristics of COPD, the experts' wisdom and patients' needs was developed. Patients with COPD can grasp it in about 3 h and participants showed 86.0% adherence to the Tai Chi training and no negative accidents occurred. Generalized estimating equations (GEE) showed that there were significant differences in FEV1%, 6MWD and CAT scores between modified Tai Chi (MTC) group and the control group over time (model group × time interaction χ2 = 13.68, P < 0.001; χ2 = 192.39, P < 0.001;χ2 = 6.05, P = 0.014, respectively), however, no statistical significance in mMRC scores was found between the 2 groups over time (model group × time interaction χ2 = 3.54, P = 0.06). The baseline of FEV1%,6MWD, mMRC scores and CAT scores are significant covariates for lung function, exercise capacity, dyspnea symptom and health status, respectively (χ2 = 149.43, P < 0.001; χ2 = 5.78, P = 0.016; χ2 = 66.71, P < 0.001; χ2 = 81.83, P < 0.001, respectively). CONCLUSIONS This modified 6-form Tai Chi routine is easy to grasp, easy to adhere to, safe to practice and effective to improve lung function, exercise capacity, health status and to prevent dyspnea symptom from getting worse for patients with COPD and it can be recommended as a suitable exercise therapy for them.

Abstract
BACKGROUND AND PURPOSE Tai Chi is a mind‐body exercise that has been shown to improve both mental and physical health. As a result, recent literature suggests the use of Tai Chi to treat both physical and psychological disorders. However, the underlying physiological changes have not been characterized. The aim of this pilot study is to assess the changes in brain metabolites and muscle energetics after Tai Chi training in an aging population using a combined brain‐muscle magnetic resonance spectroscopy (MRS) examination. METHODS Six healthy older adults were prospectively recruited and enrolled into a 12‐week Tai Chi program. A brain 1H MRS and a muscle 31P MRS were scanned before and after the training, and postprocessed to measure N‐acetylaspartate to creatine (NAA/Cr) ratios and phosphocreatine (PCr) recovery time. Wilcoxon‐signed rank tests were utilized to assess the differences between pre‐ and post‐Tai Chi training. RESULTS A significant within‐subject increase in both the NAA/Cr ratios (P = .046) and the PCr recovery time (P = .046) was observed between the baseline and the posttraining scans. The median percentage changes were 5.38% and 16.51% for NAA/Cr and PCr recovery time, respectively. CONCLUSIONS Our pilot study demonstrates significant increase of NAA/Cr ratios in posterior cingulate gyrus and significantly improved PCr recovery time in leg muscles in older adults following short‐term Tai Chi training, and thus provides insight into the beneficial mechanisms.

Abstract
PURPOSE To systematically evaluate and quantify the effects of Tai Chi/Qigong (TCQ) on motor (UPDRS III, balance, falls, Timed-Up-and-Go, and 6-Minute Walk) and non-motor (depression and cognition) function, and quality of life (QOL) in patients with Parkinson's disease (PD). METHODS A systematic search in 7 electronic databases targeted clinical studies evaluating TCQ for individuals with PD published through August 2016. Meta-analysis was used to estimate effect sizes (Hedges's g) and publication bias for randomized controlled trials (RCTs). Methodological bias in RCTs was assessed by two raters. RESULTS Our search identified 21 studies, 15 of which were RCTs with a total of 735 subjects. For RCTs, comparison groups included no treatment (n = 7, 47%) and active interventions (n = 8, 53%). Duration of TCQ ranged from 2 to 6 months. Methodological bias was low in 6 studies, moderate in 7, and high in 2. Fixed-effect models showed that TCQ was associated with significant improvement on most motor outcomes (UPDRS III [ES = -0.444, p < 0.001], balance [ES = 0.544, p < 0.001], Timed-Up-and-Go [ES = -0.341, p = 0.005], 6 MW [ES = -0.293, p = 0.06], falls [ES = -0.403, p = 0.004], as well as depression [ES = -0.457, p = 0.008] and QOL [ES = -0.393, p < 0.001], but not cognition [ES = -0.225, p = 0.477]). I2 indicated limited heterogeneity. Funnel plots suggested some degree of publication bias. CONCLUSION Evidence to date supports a potential benefit of TCQ for improving motor function, depression and QOL for individuals with PD, and validates the need for additional large-scale trials.

Abstract
BACKGROUND Diabetic peripheral neuropathy (DPN) is a common complication of type-2 diabetes mellitus (T2DM) that predisposes the elderly to a higher falls risk. Falls prevention programs with a component of weight-bearing exercises are effective in decreasing future falls in the elderly. However, weight-bearing exercise was only recently recommended in guidelines for exercise for people with T2DM and DPN. Since then, there have been an increasing number of studies to evaluate the effectiveness of falls prevention programs on this targeted population. OBJECTIVES A systematic literature review was undertaken to determine the effectiveness of falls prevention programs for people with T2DM and DPN. MAJOR FINDINGS Nine published studies that investigated the effect of exercise training on falls risk among people with T2DM and DPN were included in the review. Interventions included lower limb strengthening, balance practice, aerobic exercise, walking programs, and Tai Chi. CONCLUSIONS The preliminary evidence presented in this review suggests that people with T2DM and DPN can improve their balance and walking after a targeted multicomponent program without risk of serious adverse events. There is insufficient long-term follow-up data to determine whether the improvements in balance or strength resulted in a decrease falls risk in the community setting.

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.

Abstract
Background Chronic obstructive pulmonary disease (COPD) is a major public health problem worldwide. However, several studies that have assessed the role of traditional Chinese exercise in the management of this disease include broad variations in sample sizes and results. Therefore, this meta-analysis was conducted to assess the effects of traditional Chinese exercise on patients with COPD. Methods Two investigators independently identified and extracted data from selected articles. A computerized search of electronic databases through August 2015 was conducted. Mean differences (MDs) and 95% confidence intervals (CIs) were calculated to analyze the combined data. The methodological quality was evaluated using the Cochrane risk-of-bias tool. Heterogeneity was assessed with the I2 test. Results Ten randomized, controlled trials (RCTs) involving 622 patients met the inclusion criteria. There were significant improvements in the 6-minute walking distance test (6 MWD;MWD = 12.10 m; 95% CI, 7.56–16.65 m; p<0.001); forced expiratory volume in one second (FEV1% predicted; WMD = 9.02; 95% CI, 6.80–11.23; p<0.00001); forced expiratory volume in 1 second/forced vital capacity (FEV(1)/FVC) ratio (Tiffenau Index; WMD = 6.67; 95% CI, 5.09–8.24; p<0.00001); and quality of life, as evaluated by the Chronic Respiratory Disease Questionnaire (CRDQ; WMD = 0.85 score; 95% CI, 0.52–1.18; p<0.00001). Conclusions Traditional Chinese exercise could provide an effective alternative method for managing COPD. Larger and higher-quality trials are required.

Abstract
BACKGROUND Regular exercise training is one of the core components of multifactorial fall-prevention programs. OBJECTIVE To compare the effect of Tai Chi and combined exercise prescription that consists of three main components of an exercise prescription on static balance, dynamic balance, fear of falling and mood. METHODS Sixty older adults aged 55-76 were randomly assigned to Group 1 (Tai Chi exercise) or Group 2 (combined exercise prescription). Exercise was performed three times a week over a period of 12 weeks. Single Leg-Stance-Eyes Open (SLS-EO), Single Leg-Stance Eyes Closed (SLS-EC), computerized balance measurements, the Timed Up and Go (TUG) test, Berg Balance Scale (BBS), the Survey of Activities and Fear of Falling in the elderly (SAFFE), the Geriatric Depression Scale (GDS), and the Beck Depression Scale (BDS) were assessed before and after the final training session. RESULTS Both exercise groups yielded better results in dynamic balance assessments (TUG and BBS) at the 12th week (p< 0.05). Group 1 also showed significant improvements in the measurements of SLS-EO, SLS-EC, SAFFE, GDS, and BDS during the post-intervention period (all p< 0.05). When the groups were compared, a significant difference was found between groups in favor of Group 1 in terms of the SLS-EO and SAFFE (p< 0.05). CONCLUSIONS It can be concluded that Tai Chi may be a more successful exercise intervention for factors-related to falls in older people.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
Ratings of perceived exertion (RPE) and affective responses were assessed during Tai Chi Chuan. A total of 16 women ( M age = 61.2 yr., SD = 8.8) participated in this study. Individuals practiced Tai Chi Chuan three times / week during seven weeks, and were assessed session-by-session (21 Wu Tai Chi Chuan sessions) in three moments (15, 30, and 45 min.) using Borg's scale (CR 0–10) and the Feeling Scale (+5/–5). With regard to RPE, there was a difference between 15 and 30 min. and between 15 and 45 min. The same pattern of differences was observed for the affective response. The RPE during the seven weeks ranged from “fairly light” to “moderate” and the affective response from “good” to “very good.” Thus, Tai Chi Chuan was perceived as a low-moderate intensity and pleasurable (positive affect) exercise by middle-aged and elderly women.

Abstract
BACKGROUND There is still uncertainty concerning the beneficial effects of shoe collar height for ankle sprain prevention and very few data are available in the literature regarding the effect of high-top and low-top shoes on muscle responses during landing. The purpose of this study was to quantify the effect of high-top and low-top shoes on ankle inversion kinematics and pre-landing EMG activation of ankle evertor muscles during landing on a tilted surface. METHODS Thirteen physical education students landed on four types of surfaces wearing either high-top shoes (HS) or low-top shoes (LS). The four conditions were 15° inversion, 30° inversion, combined 25° inversion + 10° plantar flexion, and combined 25° inversion + 20° plantar flexion. Ankle inversion kinematics and EMG data of the tibialis anterior (TA), peroneus longus (PL), and peroneus brevis (PB) muscles were measured simultaneously. A 2 × 4 (shoe × surface) repeated measures ANOVA was performed to examine the effect of shoe and landing surfaces on ankle inversion and EMG responses. RESULTS No significant differences were observed between the various types of shoes in the maximum ankle inversion angle, the ankle inversion range of motion, and the maximum ankle inversion angular velocity after foot contact for all conditions. However, the onset time of TA and PB muscles was significantly later wearing HS compared to LS for the 15° inversion condition. Meanwhile, the mean amplitude of the integrated EMG from the 50 ms prior to contact (aEMGpre) of TA was significantly lower with HS compared to LS for the 15° inversion condition and the combined 25° inversion + 20° plantarflexion condition. Similarly, the aEMGpre when wearing HS compared to LS also showed a 37.2% decrease in PL and a 31.0% decrease in PB for the combined 25° inversion + 20° plantarflexion condition and the 15° inversion condition, respectively. CONCLUSION These findings provide preliminary evidence suggesting that wearing high-top shoes can, in certain conditions, induce a delayed pre-activation timing and decreased amplitude of evertor muscle activity, and may therefore have a detrimental effect on establishing and maintaining functional ankle joint stability.

Abstract
OBJECTIVES To examine the effects of Tai Chi on balance and functional mobility in people with Parkinson's disease, and determine whether fall incidence could be reduced by the Tai Chi exercise. DESIGN Single blinded randomized control trial with 6 months' follow-up. SETTING A hospital and general community. PARTICIPANTS Patients (n=76) diagnosed with idiopathic Parkinson's disease, over 40 years old, able to walk independently and fell at least one time during the past 12 months. INTERVENTIONS The Tai Chi group (n=37) received 24-form Yang style Tai Chi exercise for 60 minutes each time, three times a week and lasted for 12 weeks. The control group (n=39) received no intervention. MAIN OUTCOME MEASURES Berg Balance Scale (BBS), Unified Parkinson's Disease Rating Scale (UPDRS) III, Timed Up&Go (TUG) and occurrences of falls. RESULTS The Tai Chi group improved more than the control group on the BBS (p<0.05), but there was no difference on UPDRS III scores and Timed Up&Go (p>0.05). During the 6-month follow-up, only 8 (21.6%) out of 37 patients in the Tai Chi group had experience of falls comparing to 19 (48.7%) out of 39 patients in the control group (p<0.05). The average times of falls were 0.30±0.62 in the Tai Chi group compared with 0.64±0.74 in the control group (p<0.05). CONCLUSIONS Our findings suggested that Tai Chi exercise could improve the balance and decrease the fall risks in patients with Parkinson's disease.

Abstract
This study aimed to evaluate the effectiveness of an innovative exercise program on muscle strength, balance, and gait kinematics in elderly community-dwellers. The exercise program included strength and balance training and the 8-form Tai Chi Chuan. The measurements were carried out at baseline and 12 weeks, and consisted of four physical performance tests, joint isokinetic strength tests, and three-dimensional gait analysis. Fifty-six community-dwelling older adults aged 60–80 years old were randomly assigned to an intervention or control group. After 12 weeks, the intervention group showed a 17.6% improvement in the timed up and go test, accompanied by a 54.7% increase in the 30-second chair stand test score. Significant increases in the score of star excursion balance tests, and the strength of the extensor and flexor muscles at knee and ankle joints were also observed. In addition, the intervention group walked at a faster speed with a longer step length, shorter support phase, and a greater sagittal plane range of motion at the hip and ankle joints. No statistical improvements were seen in the control group. This study provided an effective, evidence-based falls prevention program that can be implemented in community settings to improve physical fitness and reduce fall risks among community-dwelling older adults. The star excursion balance test could be a sensitive measure of physical performance for fall risk assessment in older people.
