BACKGROUND

The effectiveness of Traditional Chinese exercises in promoting functional recovery in patients with chronic ankle instability, as well as the potential impact of variables such as intervention type, duration, frequency, and cycle on treatment outcomes, still requires further investigation.

METHODS

Literature searches were conducted in multiple databases including China National Knowledge Infrastructure (CNKI), VIP, Wanfang, China Biomedical Literature Database (CBM), PubMed, EBSCO(Medline、CINAHL、SPORTDiscus), Embase, Cochrane Library, ProQuest, and Web of Science for randomized controlled trials assessing the effects of Traditional Chinese Exercises interventions on patients with Chronic Ankle Instability. The publication timeframe spanned from the inception of each database until January 20, 2025. Meta-analysis was performed using STATA 15 software on the included studies.

RESULTS

Twelve randomized controlled trials (RCTs) involving 323 patients were included in this analysis. Compared with the control group, Traditional Chinese exercises showed the following improvements: CAIT: WMD = 4.02, 95 % CI [3.22, 4.81], z = 9.90, P < 0.001.Balance: ANT: SMD = 0.38, 95 % CI [0.18, 0.59], z = 3.71, P = 0.003.PM: SMD = 0.49, 95 % CI [0.26, 0.70], z = 4.73, P < 0.001.PL: SMD = 0.67, 95 % CI [0.46, 0.88], z = 6.35, P < 0.001.C: SMD = 0.80, 95 % CI [0.35, 1.25], z = 3.51, P < 0.001.JPS:Plantarflexion: SMD = -0.58, 95 % CI [-0.94, -0.21], z = 3.09, P = 0.002.Inversion: SMD = -0.46, 95 % CI [-0.86, -0.06], z = 2.23, P = 0.025.Muscle Strength: Plantarflexion: SMD = 0.81, 95 % CI [0.43, 1.18], z = 4.25, P < 0.001.Inversion: SMD = 0.66, 95 % CI [0.25, 1.07], z = 3.16, P = 0.002.Eversion: SMD = 1.04, 95 % CI [0.62, 1.46], z = 4.82, P < 0.001.Subgroup Analysis: Tai Chi training conducted twice weekly for a 12-week intervention period, with 60-minute sessions, demonstrated the most effective improvements.

LEVEL OF EVIDENCE

The evidence level for the effects of Traditional Chinese exercises on Balance-ANT, Balance-PM, and Balance-PL balance directions in CAI patients is rated as "moderate."

CONCLUSION

Traditional Chinese exercise has been shown to significantly improve balance, muscle strength, and joint position sense in CAI patients. Based on the current findings, Tai Chi training appears to provide greater benefits for CAI patients. It is recommended that CAI patients participate in Tai Chi training twice a week, with each session lasting 60 minutes, over a 12-week period.

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.

The Effect and Safety of Xuefu Zhuoyue Prescription for Coronary Heart Disease: An Overview of Systematic Reviews and Meta-Analyses

Background. In China, the traditional Chinese medicine compound Xuefu Zhuoyue prescription (XFZY) has been widely used in the therapy of coronary heart disease (CHD). Currently, several systematic reviews (SRs)/meta-analyses (MAs) of XFZY for the treatment of CHD have been published. This overview aims to evaluate the existing SRs/MAs and provide a scientific basis for evaluating the efficacy and safety of XFZY for the therapy of CHD. Methods. The SRs/MAs of XFZY for the treatment of CHD were obtained from 7 electronic databases with the search date set at March 7, 2022. Two researchers independently assessed the methodological quality, reporting quality, and evidence quality of the included SRs/MAs using the following tools: the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2), the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 (PRISMA 2020), and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. Results. A total of 11 SRs/MAs were included in this overview. All SRs/MAs assessed by means of AMSTAR-2 had more than one critical defect, so all SRs/MAs were rated low. Regarding the assessment of reporting quality, the results of PRISMA 2020 showed that none of the SRs/MAs were fully reported. In addition, the results of the GRADE assessment of the quality of evidence indicated that only one outcome was rated as high quality across all SRs/MAs. Conclusion. Current evidence suggests that XFZY is effective and safe for the management of patients with CHD. However, the high risk of bias of the original clinical studies and the low quality of the SRs/MAs reduced the reliability of the results.

Concepts and Application of Tai Ji in Stroke Rehabilitation: A Narrative Review

Stroke remains a leading cause of adult disability, and it decreases the health-related quality of life due to functional disability and poor functional recovery in stroke. Tai Ji has been recently introduced to overcome disabilities. This review aims to explain the effects of Tai Ji on functional recovery in stroke patients, linking it to current approaches, concepts and therapies such as Bobath and proprioceptive neuromuscular facilitation techniques. A compilation of recent literature on Tai Ji's use in stroke rehabilitation from Google scholar and PubMed Central (2018 to 2022). The benefits of Tai Ji in stroke functional recovery were studied and explained based on its similarity in concepts to current conventional stroke rehabilitation approaches. There were few randomized controlled trials on Tai Ji in functional recovery among stroke patients. However, all literature identified Tai Ji as beneficial in stroke rehabilitation. However, there was no literature on explaining the Tai Ji movement based on current conventional stroke rehabilitation approaches. Tai Ji carries similar theories to the current neurorehabilitation approach. Tai Ji can be modified and incorporated into stroke rehabilitation programs based on patients' needs to produce promising outcomes.

Reliability of Evidence to Guide Decision-Making in the Use of Acupuncture for Postpartum Depression

Background

There is conflicting evidence on the effectiveness of acupuncture in the treatment of postpartum depression (PPD). This study aimed to assess previous systematic reviews/meta-analyses (SRs/MAs) on the effectiveness of acupuncture to treat PPD.

Method

SRs/MAs regarding the use of acupuncture for PPD were identified from the establishment of digital databases to November 2021. The Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2) was applied to evaluate the methodological quality of included SRs/MAs. The Grades of Recommendations, Assessment, Development and Evaluation (GRADE) was utilized to evaluate the evidence quality for outcomes of interest.

Results

Six studies that conducted quantitative syntheses were included. According to AMSTAR-2, the methodological quality of these SRs/MAs was critically low owing to limitations of items 2, 4, and 7. According to GRADE, no study included high-quality evidence and most studies included low-quality evidence.

Conclusions

Acupuncture m be beneficial for PPD, however, due to limitations of current evidence and inconsistent findings, further studies are needed to provide stronger evidence to draw definitive conclusions.
