Traditional Chinese Mind and Body Exercises for Promoting Balance Ability of Old Adults: A Systematic Review and Meta-Analysis

Optimal exercise parameters of Baduanjin for balance in older adults: a systematic review and meta-analysis

Purpose

Baduanjin represents an affordable and secure method of exercising both the mind and body, and has been observed to enhance balance in older adults. Nevertheless, the existing research on the impact of Baduanjin on various balance functions is still insufficient, and the optimal dosage parameters for performing Baduanjin exercises have not been studied.

Methods

To conduct a systematic review and meta-analysis, five English databases and three Chinese databases were performed. Relevant studies were searched by GOOGLE SCHOLAR, Web of Science, Cochrane, Embase, Pubmed, CNKI, SinoMed, and WangfangMed using "Baduanjin" and "balance." Subgroup analyses were conducted to investigate the influence of different exercise parameters on the observed outcomes. Meta-regression was employed to identify potential moderating factors. The Physical Therapy Evidence Database (PEDro) scale was used for quality assessment.

Results

A total of 40 studies were included in the analysis, while the majority of studies report promising outcomes, the overall quality of these studies is relatively low. The results of the meta-analysis showed Baduanjin significantly enhanced static balance (SMD = 0.87, 95%CI: 0.69-1.05), dynamic balance (SMD = 0.85, 95%CI: 0.50-1.19), proactive balance (SMD = -1.00, 95%CI: -1.33--0.67) and balance test battery (SMD = 1.04, 95%CI: 0.81-1.28) in older adults. Additionally, the findings indicated a notable reduction in the risk of falls (SMD = -2.19, 95%CI: -3.35--1.04) and an improvement in fall efficacy (SMD: 0.57, 95%CI: 0.36-0.78).

Conclusion

Baduanjin has been demonstrated to improve balance and reduce the risk of falls in older adults. Studies have found that significant gains begin to be achieved with a minimum of 12 weeks of practice and that 30-49 min of practice, 5-7 times per week, works best for developing different balances. However, most of the included studies were limited by a lack of blinding and follow-up visits, and there was an insufficient number of short-term or long-term studies to establish complete optimal parameters robustly.

Efficacy of traditional Chinese exercises in patients with post-COVID-19 chronic fatigue syndrome: A protocol for systematic review and meta-analysis

BACKGROUND

Some patients develop long-term symptoms after Corona virus disease 2019 (COVID-19), and chronic fatigue syndrome (CFS) is one of the main symptoms. CFS is characterized by fatigue lasting for more than 6 months accompanied by sleep disorders, anxiety, and depression, which causes a certain degree of harm to both physiological and psychological aspects of the individual. Traditional Chinese exercises (TCEs) are an ancient Chinese therapy and has recently been reported to be effective for CFS. Therefore, we will conduct a systematic review and meta-analysis aiming to accurately evaluate the efficacy of TCEs on post-COVID-19 CFS and provide an alternative treatment for post-COVID-19 CFS.

METHODS

Seven databases (PubMed, Ovid Embase, Cochrane Library, Web of Science, Chinese National Knowledge Infrastructure (CNKI), China Biology Medicine (CBM), and Wanfang) will be searched from establishment to August 2022, and we will only include randomized controlled trials of TCEs for post-COVID-19 CFS. Two reviews will independently include the research according to the inclusion and exclusion criteria. Review Manager 5.2 software will be used to analyze the accepted literature, and the relative risk ratio (RR) and 95% confidence interval (CI) will be used as effect indicators for the outcome indicator dichotomous variables. For continuous variables, weighted mean difference (MD) and 95% CI will be used as effect indicators. The heterogeneity test will be assessed using the I2 statistic and Q statistic. The PEDro scale was used to evaluate the methodological quality of the included studies. Subgroup analysis was performed according to different TCEs, age, gender, and duration of CFS.

RESULTS

This systematic review and meta-analysis will evaluate the efficacy of TCEs in post-COVID-19 CFS.

CONCLUSION

The results of this study will provide reliable evidence for the effects of TCEs for post-COVID-19 CFS on patients' fatigue, anxiety, depression, sleep, and quality of life.

Effects of Therapeutic Horseback-Riding Program on Social and Communication Skills in Children with Autism Spectrum Disorder: A Systematic Review and Meta-Analysis

Animal-assisted therapy has become a fast-growing and effective approach for remediating core impairments of children with ASD; however, recent systematic review studies on the effects of AAT in children with ASD have some limitations, including referral to a variety of animal-assisted interventions rather than to horseback-riding therapy alone and the absence of any meta-analysis in systematic reviews. A complete systematic review of the studies that describe the use of THR as an intervention is needed to specifically target the core impairments of children with ASD. The purpose of this study was to employ the systematic review method to synthesize research findings regarding the effects of THR programs on the social interaction and communication skills of children with ASD. We conducted a structured search in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched for potentially relevant studies in five databases (Web of Science, PubMed, CINAHL, Scopus, and SPORTDiscus) from inception until February 2022. In addition, we manually searched the bibliographies of the included studies to find articles that might otherwise have been missed. We considered articles eligible or ineligible if they satisfied specific inclusion or exclusion criteria. Our results showed that the THR program is an effective direct and alternative therapeutic program that can considerably improve the social behaviors and communication skills of children with ASD and can effectively impact autistic impairments in areas such as social awareness, social cognition, social motivation, and social communication. These findings are in line with those of previous studies; however, we did not find statistical evidence of any effect of THR on the autistic behaviors of irritability, stereotypy, and inappropriate speech. In conclusion, the findings produced by this meta-analysis study provide evidence that THR programs can considerably improve the social behaviors and communication skills of children with ASD.

Impact of current or past physical activity level on functional capacities and body composition among elderly people: a cross-sectional analysis from the YMCA study

Background

Physical activity (PA) is recognized as important predictor of healthy aging. However, the influence of the type of voluntary PA as well as age or sex in this relationship is unclear. Thus, we assess the association between current and past PA level and physical performances among voluntary active older adults.

Methods

Functional capacities (timed Up and Go, sit-to-stand, alternate step test, unipodal balance, grip strength, knee extension strength, estimated muscle power and VO2 max) as well as body composition (DXA: total and appendicular lean masses (LM; kg), fat mass (FM; %)) were measured. Current and last 5-years PA level (time spent on total, aerobic, resistance and body & mind activities) were assessed using an interview. Multiple regressions, adjusted on age, sex and BMI, were performed to assess the relationship between current or past PA level and physical performances. Sub-group analysis, according to the sex (men/women) or age (< 65 yrs. vs. ≥65 yrs) were performed.

Results

525 subjects (age:61.7 ± 8.1 yrs.; women:68.9%; BMI:26.4 ± 4.8 kg/m²) were enrolled in this study. After adjustment on confounding factors, total current PA level has positive impact on total FM (β = − 2.09, p = 0004) and balance (β = 0.10; p = 0.05). Moreover, current body & mind activities influence total LBM (β = − 0.22, p = 0.02) and balance (β = 0.17; p = 0.001) whereas resistance activities influence total LBM (β = 0.17; p = 0.05), FM (β = − 0.16; p = 0.04) and sit-to-stand capacities (β = − 0.10; p = 0.05). Globally, these results were more pronounced in women than in men and among people aged over 65 years. Past level of PA has low impact on functional capacities and body composition, regardless of sex. Among people < 65 years, there is no relationship between time spent on total PA and functional capacities or body composition. However, a significant correlation was found between past total PA and balance (r=` 0.19; p = 0.01), alternate-step test (r = 0.24; p = 0.02) and VO2max (r = 0.19; p = 0.02) in people aged over 65 years. More precisely, the past time spent on aerobic and resistance activities influence balance (r = 0.16; p = 0.03 and r = 0.15; p = 0.04, respectively) after 65 yrs. old.

Conclusion

Even if physical activity history has little influence on physical aging process, being active is associated with body composition and functional capacities, especially among women aged 65 years and over.

Optimal exercise parameters of tai chi for balance performance in older adults: A meta-analysis

BACKGROUND

Tai chi is considered a safe and low-cost treatment for improving balance ability among an older population. However, there is no existing evidence on the optimal exercise parameters of tai chi for improving balance in older adults.

OBJECTIVES

To investigate the optimal parameters of a tai chi intervention to improve balance performance of older adults.

DESIGN

Systematic review and meta-analysis of randomized controlled trials (RCTs).

SETTING

PubMed, Embase, Cochrane Library, Web of Science, Scopus, China National Knowledge Infrastructure, Wanfang, Chinese Science and Technology Periodical and China Biology Medicine were searched from inception until November 30, 2020.

PARTICIPANTS

Adults aged 60 years and over.

MEASUREMENTS

Two reviewers independently extracted the data and assessed the quality of the included studies according to the Physiotherapy Evidence Database (PEDro) scale. Subgroup analyses and meta-regressions were conducted to elucidate the impact of tai chi training programs on balance measures.

RESULTS

Twenty-six eligible RCTs were included in the meta-analysis. Pooled results showed that tai chi has moderate effects for improving proactive balance (weighted mean standardized mean differences [SMD_wm ] = 0.61, 95% CI 0.33-0.89) and static steady-state balance (SMD_wm  = 0.62, 95% CI 0.30-0.95) and small effects for improving dynamic steady-state balance (SMD_wm  = 0.38, 95% CI 0.03-0.73) and balance test batteries (SMD_wm  = 0.47, 95% CI 0.13-0.81) in adults over 60 years of age. The practice frequency could predict the effects of tai chi on static steady-state balance, and the 24-form simplified Yang style tai chi (45-60 min/session, more than four sessions per week and at least 8 weeks) was the most optimal.

CONCLUSIONS

Tai chi is effective at improving the balance ability of adults over 60 years of age. A medium duration and high frequency of 24-form tai chi may be the optimal program for improving balance, but this evidence should be recommended with caution due to limitations of the methodology and small sample sizes.

Effects of Mind-Body Exercises on Schizophrenia: A Systematic Review With Meta-Analysis

BACKGROUND

Mind-body exercises (MBEs) have been widely accepted as a complementary therapy for the patients with low exercise tolerance. Currently, the number of experimental studies investigating the effect of MBEs for improving symptoms in people with schizophrenia is increasing. However, results are inconsistent.

METHODS

We systematically reviewed and meta-analyzed the effects of mind-body exercises on schizophrenia. Seven electronic databases (Pubmed, Web of Science, PsycINFO, Embase, Cochrane Central Register of Controlled Trials [CENTRAL], CNKI and Wangfang) were screened through October 2019 and risks of bias of included studies were assessed in Review Manager 5.3.

RESULTS

Meta-analysis on 13 studies with 1,159 patients showed moderately significant effects in favor of mind-body exercise intervention to improve positive symptoms (SMD = 0.31; 95% CI 0.01 to 0.60; p = 0.04), negative symptoms (SMD = 0.37; 95% CI 0.14 to 0.60; p = 0.002), and depression (SMD = 0.88; 95% CI 0.63 to 1.13; p<0.00001). Meta-regression analysis revealed that the improvement in positive symptoms was positively associated with the frequency of intervention (p = 0.04), while a marginally significant correlation was observed between the improved negative symptoms and duration of each session (p = 0.06).

CONCLUSIONS

This meta-analysis supports the therapeutic effects of MBEs to aid in the treatment of schizophrenia. Further studies need to incorporate rigorous design and large sample size to identify the optimal type and dose of mind-body exercise to inform clinical practices on MBEs' recommendations for the management of schizophrenia symptoms.

The benefits and mechanisms of exercise training for Parkinson's disease

Parkinson's disease (PD) is a significantly progressive neurodegenerative disease characterised by both motor and nonmotor disorders. The main pathological characteristics of PD consist of the loss of dopaminergic neurons and the formation of alpha-synuclein-containing Lewy bodies in the substantia nigra. Currently, the main therapeutic method for PD is anti-Parkinson medications, including levodopa, madopar, sirelin, and so on. However, the effect of pharmacological treatment has its own limitations, the most significant of which is that the therapeutic effect of dopaminergic treatments gradually diminishes with time. Exercise training, as an adjunctive treatment and complementary therapy, can improve the plasticity of cortical striatum and increase the release of dopamine. Exercise training has been proven to effectively improve motor disorders (including balance, gait, risk of falls and physical function) and nonmotor disorders (such as sleep impairments, cognitive function and quality of life) in PD patients. In recent years, various types of exercise training have been used to treat PD. In this review, we summarise the exercise therapy mechanisms and the protective effects of different types of exercise training on PD patients.

Study protocol for a single-blind randomised controlled trial to evaluate the clinical effects of an Integrated Qigong exercise intervention on freezing of gait in Parkinson's disease

INTRODUCTION

Qigong exercise offers a potentially safe, low-cost and effective mind-body rehabilitative intervention for mitigating the problem of gait interruption among patients with Parkinson's disease (PD) who have frequent freezing of gait (FOG) episodes. However, its clinical effects have not been established. This paper describes the trial protocol of evaluating the clinical efficacy of a newly developed Integrated Qigong in improving gait among patients with PD who have FOG.

METHODS AND ANALYSIS

A single-blind randomised controlled trial is designed to compare Integrated Qigong and balance training with an attention control. Participants will be patients with mild to moderate PD who experience FOG and are recruited from local communities in Shanghai, China. Participants will be randomly allocated to one of the three groups: Integrated Qigong group, a balance exercise intervention group, or control group. The total number of participants will be 126, and masked assessments will be made at baseline, 12 weeks (end of intervention) and 12-week follow-up. Both Integrated Qigong group and balance training group will receive a group-based exercise intervention that meets three times per week, 60 min in duration, for 12 weeks. The control group will receive a 60 min weekly group session and monthly health education. The primary outcomes are gait parameters (stride length, gait velocity, stride time variability) and occurrence of FOG. The secondary outcomes are postural instability, walking disability, falling, fear of falling and quality of life.

ETHICS AND DISSEMINATION

This study has been approved by the Ethics Committee of Shanghai University of Sport and registered at China Clinical Trial Registry. Participants will sign informed consent prior to the participation of the trial. The findings of the study will be published in peer-reviewed academic journals and disseminated to PD support groups, medical community and media.

The Effects of Mind-Body Exercise on Cognitive Performance in Elderly: A Systematic Review and Meta-Analysis

Background: As the situation of cognitive aging is getting worse, preventing or treating cognitive decline through effective strategies is highly important. This systematic review aims to investigate whether mind-body exercise is an effective approach for treating cognition decline. Methods: Searches for the potential studies were performed on the eight electronic databases (MEDLINE, Scopus, Web of Science, SPORTDiscus, CINAHL, PsycArtilces, CNKI, and Wanfang). Randomized controlled trials (RCTs) examining the effect of mind-body exercise on cognitive performance in older adults were included. Data were extracted and effect sizes were pooled with 95% confidence intervals (95% CI) using random-effects models. The Physiotherapy Evidence Database Scale was employed to examine the study quality. Results: Nineteen RCTs including 2539 elders (67.3% female) with fair to good study quality were identified. Mind-body exercise, relative to control intervention, showed significant benefits on cognitive performance, global cognition (Hedges'g = 0.23), executive functions (Hedges'g = 0.25 to 0.65), learning and memory (Hedges'g = 0.37 to 0.49), and language (Hedges'g = 0.35). In addition, no significant adverse events were reported. Conclusion: Mind-body exercise may be a safe and effective intervention for enhancing cognitive function among people aged 60 years or older. Further research evidence is still needed to make a more conclusive statement.
