Acupuncture for spasticity after stroke: a systematic review and meta-analysis of randomized controlled trials

Acupuncture and Acupoints for Managing Pediatric Cerebral Palsy: A Meta-Analysis of Randomized Controlled Trials

BACKGROUND

Acupuncture is frequently used to manage pediatric cerebral palsy (CP), yet updated evidence is needed to guide future research and clinical practice.

METHODS

Seven databases were searched from 1994 to 26 June 2023. Randomized controlled trials (RCTs) involving body, scalp, or ear acupuncture for managing CP, excluding acupoint injection, catgut embedding, electro-acupuncture, or laser acupuncture, were included.

RESULTS

Twenty RCTs with 1797 participants were analyzed. Acupuncture groups had better improvements in gross motor function measure (GMFM) scores by 5% (mean difference: 5.93, 95% CI: 3.67-8.19, p < 0.001, I2 = 57%); a 16% higher probability to yield prominent improvement in effectiveness rate (ER) (risk ratio: 1.16, 95% CI: 1.08-1.25, p < 0.001, I2 = 0%); and better outcomes in the Modified Ashworth Scale (MAS) (standardized mean difference [SMD]: 0.3, 95%, CI: 0.11-0.49, p < 0.001, I2 = 0%), the Berg Balance Scale (BBS) (SMD: 2.48; 95% CI: 2.00-2.97, p < 0.001, I2 = 72%) and ADL (SMD: 1.66; 95% CI: 1.23-2.08, p < 0.001, I2 = 91%). Studies with eight core acupoints identified from all ninety-five acupoints had better ER.

CONCLUSIONS

Acupuncture, especially using core acupoints, may be effective for managing symptoms in children with CP.

Comparing the effects of different acupoint-stimulating therapies in mitigating post-stroke spasticity and motor dysfunction in older stroke survivors: A network meta-analysis of randomized trials

Acupoint-stimulating therapies have often been used to manage stroke-related spasticity and motor dysfunction. However, the effects of different acupoint-stimulating therapies in older stroke survivors have been unclear. This systematic review and network meta-analysis compared the effects of different acupoint-stimulating therapies in managing spasticity and motor dysfunction in older stroke survivors. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched 7 databases for studies published up to July 2023. Inclusion criteria were: (1) older adults with strokes; (2) treatments were acupoint-stimulating therapies; (3) a control group did not receive acupoint-stimulating therapy, or the study compared different acupoint-stimulating therapies; and (4) outcomes included spasticity and motor function. Methodological quality was assessed with Risk-of-bias tool for randomized trials version 2, while R and Metainsight were used to conduct the network meta-analysis. We analyzed 27 studies and the results showed that non-invasive electroacupuncture and warm acupuncture were more effective in reducing spasticity than conventional acupuncture (standardized mean difference and 95 % confidence intervals = 1.35/1.19 [0.57; 2.13/0.54; 1.83]) and invasive electroacupuncture (standardized mean difference and 95 % confidence intervals = 0.96/0.80 [0.12; 1.80/0.08; 1.51]). Conventional acupuncture and invasive electroacupuncture were effective in improving motor function (standardized mean difference and 95 % confidence intervals = 0.99/1.41 [0.42; 1.56/0.54; 2.28]). However, there was significant inconsistency for the effects of invasive electroacupuncture between studies. Our findings suggest that for older stroke survivors with spasticity, non-invasive electroacupuncture and warm acupuncture are appropriate, whereas conventional acupuncture is more appropriate for patients aiming for motor recovery. SYSTEMATIC REVIEW REGISTRATION: This study was registered in the PROSPERO database (CRD42023442202).

Acupuncture, an effective treatment for post-stroke neurologic dysfunction

Stroke episodes represent a significant subset of cerebrovascular diseases globally, often resulting in diverse neurological impairments such as hemiparesis, spasticity, dysphagia, sensory dysfunction, cognitive impairment, depression, aphasia, and other sequelae. These dysfunctions markedly diminish patients' quality of life and impose substantial burdens on their families and society. Consequently, the restoration of neurological function post-stroke remains a primary objective of clinical treatment. Acupuncture, a traditional Chinese medicine technique, is endorsed by the World Health Organization (WHO) for stroke treatment due to its distinct advantages in managing cerebrovascular diseases, including ischemic stroke. Numerous clinical studies have substantiated the efficacy of acupuncture in ameliorating neurological dysfunctions following stroke. This review systematically examines the improvements in post-stroke neurological dysfunction attributable to acupuncture treatment and elucidates potential mechanisms of action proposed in recent years. Additionally, this article aims to present novel therapeutic concepts and strategies for the clinical management of post-stroke neurological dysfunction.

Effect of Specific mode electroacupuncture stimulation combined with NGF during the ischaemic stroke: Study protocol for a randomized controlled trial

BACKGROUND

The emergence of the Nerve Growth Factor (NGF) has promoted the development of neuroprotective therapy; however, it has little effect on cerebral ischemia because of its poor Blood-Brain Barrier (BBB) permeability. Specific Mode Electroacupuncture Stimulation (SMES) can open BBB safely and effectively; however, it has shown inconclusive clinical effects and indirect clinical evidence in the recovery phase. Hence, the authors conducted a multicentre, randomized, placebo-controlled, assessor-blinded clinical trial to assess the effectiveness and safety of SMES combined with NGF treatment used during ischaemic stroke recovery.

METHODS

A total of 288 stroke patients from three hospitals will be recruited and randomly allocated to four groups: acupuncture + placebo, acupuncture + NGF, SMES + placebo, and SMES + NGF, in a 1:1:1:1 ratio. Assessment data will be collected at baseline, 2-weeks, and 4-weeks during the treatment period, as well as at the 4-week and 8-week follow-up after treatment completion. The primary outcome measure will be the basic cure rate. The secondary outcome measures include the simplified Modified Barthel Index, Timed Up and Go Test, Fugl-Meyer Assessment of Motor Function Score, Tinetti Performance Oriented Mobility Assessment, Montreal Cognitive Assessment, and Loewenstein Occupational Therapy Cognitive Assessment. Moreover, resting-state functional magnetic resonance imaging and Functional near-infrared spectroscopy can detect changes in cerebral blood flow and brain function and investigate the relationship between the clinical efficacy and mechanism of the prescribed interventions.

CONCLUSION

This study will provide clinical evidence for the efficacy and safety of SMES combined with NGF in the treatment of stroke patients.

Stretching exercises in managing spasticity: effectiveness, risks, and adjunct therapies

Spasticity is a component of upper motor neuron disorders and can be seen in neurological conditions like stroke and multiple sclerosis. Although the incidence rate of spasticity is unknown, it can put pressure on the health condition of those with spasticity, and there is no absolute effective way to control it. In the past, stretching exercises were an accessible tool for physical therapists to manage and control spasticity, but opinions on the optimal dose, aftereffects, and mechanism of effects were controversial. Therefore, this article tries to provide an overview of the effectiveness and risks of stretching exercises. Furthermore, there are several adjunct therapies, such as brain stimulation and botulinum injection, that can increase the effectiveness of a simple stretch by increasing cortical excitability and reducing muscle tone and their role is evaluated in this regard. The results of this study propose that several prospective and case studies have demonstrated the benefits of stretching to control spasticity, but it seems that other methods such as casting can be more effective than a simple stretch. Therefore, it is better to use stretching in combination with other therapeutic regimes to increase its effectivity of it.

Scalp acupuncture for post-stroke spastic hemiparesis: A systematic review and meta-analysis

BACKGROUND

Spastic paralysis is one of the most common sequelae of stroke, severely affecting patients' limb function and reducing their quality of life. Scalp acupuncture (SA) has been shown to significantly improve cerebral blood supply and reduce the severity of limb spasticity. This meta-analysis aims to systematically evaluate the clinical efficacy of SA in the treatment of post-stroke spastic paralysis, providing evidence-based medicine for clinical management of this condition.

METHODS

We comprehensively searched databases including China National Knowledge Infrastructure, Wanfang Data, VIP Chinese Science and Technology Periodical Database, China Biomedical Literature Database, PubMed, Embase, and Cochrane Library. Randomized controlled trials investigating the efficacy of SA in post-stroke spastic paralysis were identified until July 28, 2023. Meta-analysis was conducted using RevMan 5.4 and Stata17.0.

RESULTS

A total of 16 studies were included. Meta-analysis showed that the modified Ashworth spasticity assessment scale in the SA group was significantly higher than that in the rehabilitation group (mean difference [MD] = -0.56, 95% confidence interval [CI] [-0.75, -0.37], Z = 5.67, P < .00001). The simplified Fugl-Meyer motor function assessment scale in the SA group was significantly higher than that in the rehabilitation group (MD = 5.86, 95% CI [3.26, 8.46], Z = 4.41, P < .0001). The modified Barthel index assessment scale in the SA group was significantly higher than that in the rehabilitation group (MD = 5.79, 95% CI [4.73, 6.84], Z = 10.77, P < .00001). Additionally, the clinical effective rate in the SA group was significantly higher than that in the rehabilitation group (relative risk = 1.25, 95% CI [1.16, 1.36], Z = 5.42, P < .00001).

CONCLUSION

SA combined with rehabilitation therapy has certain advantages in reducing limb spasticity, improving limb function, and enhancing activities of daily living in patients with post-stroke spastic paralysis. This study provides reference and theoretical support for the promotion of SA in the treatment of this condition.

Corticospinal tract: a new hope for the treatment of post-stroke spasticity

Stroke is the third leading cause of death and disability worldwide. Post-stroke spasticity (PSS) is the most common complication of stroke but represents only one of the many manifestations of upper motor neuron syndrome. As an upper motor neuron, the corticospinal tract (CST) is the only direct descending motor pathway that innervates the spinal motor neurons and is closely related to the recovery of limb function in patients with PSS. Therefore, promoting axonal remodeling in the CST may help identify new therapeutic strategies for PSS. In this review, we outline the pathological mechanisms of PSS, specifically their relationship with CST, and therapeutic strategies for axonal regeneration of the CST after stroke. We found it to be closely associated with astroglial scarring produced by astrocyte activation and its secretion of neurotrophic factors, mainly after the onset of cerebral ischemia. We hope that this review offers insight into the relationship between CST and PSS and provides a basis for further studies.

The efficacy and safety of acupoint catgut embedding therapy for depression: a protocol for systematic review and meta-analysis

Background

Depression is a common public health problem, characterized by persistent low mood, lack of pleasure and exhaustion. Conventional treatments such as antidepressants and psychotherapy have some limitations, including variable efficacy, adverse side effects and high costs. Acupoint catgut embedding (ACE) therapy, as a subtype of acupuncture, has gained increasing clinical application due to its long-term effects, higher patient compliance, and cost-effectiveness. This study aims to conduct a meta-analysis to evaluate the efficacy and safety of ACE for depression.

Methods

Electronic searches will be conducted in 12 databases (both in English and Chinese databases), encompassing from inception to April 2022, without language restrictions. Randomized controlled trials (RCTs) that involve ACE for treating depression will be included. The primary outcome measures will include the response rate, Hamilton Depression Rating Scale (HAMD), Beck Depression Inventory (BDI), and Traditional Chinese Medicine Symptom Scale (TCMSSS). The secondary outcome measure will include Quality of Life scale score (QoL) and the incidence of adverse events. Results will be presented as risk ratios for dichotomous data and mean differences for continuous data. Two reviewers will independently conduct study selection, data extraction, and quality assessment. The methodological quality of eligible studies will be evaluated according to the criteria specified by the Cochrane Handbook for Systematic Reviews of Interventions (Version 5.1.0). Meta-analysis will be performed by RevMan 5.3 software.

Discussion

Due to the limitations, a safer, high-efficacy and non-pharmacological intervention with minimal side effects is required for treating depression. ACE has the advantages of longer-lasting effects, improved patient compliance, and reduced treatment costs. This protocol represents a meta-analysis and systematic review, aiming to present the current evidence regarding the efficacy and safety of ACE for depression. It seeks to provide clinicians with a theoretical basis and valuable references for complementary and alternative medicine therapies in their treatment approaches.

Improving Upper Limb Spasticity in Patients with Stroke by Electroacupuncture Therapy: a Pre- and Post-Treatment Study

Background

: Post-stroke upper limb spasticity (PS-ULS) causes a decline in the quality of life of patients by reducing their ability to perform normal daily activities.

Objectives

: We performed pre- and post-treatment analyses of the changes in stroke patients with ULS following constant electroacupuncture therapy (EAT).

Methods

: Thirty patients with PS-ULS underwent 12 sessions of EAT over 4 weeks. After performing acupuncture therapy at four acupoints on the affected arm (LI11, LI10, LI4, and TE5), electrostimulation (60 Hz) was performed for 20 min. The modified Ashworth scale (MAS) and the Fugl-Meyer assessment of the upper extremity (FMA-UE) were measured as the outcome variables.

Results

: Following EAT, there was a significant decrease in the elbow MAS score (p < 0.001), a significant decrease in the wrist MAS score (p < 0.01), and a significant increase in the FMA-UE score (p < 0.001). Adverse events related to EAT were not reported.

Conclusion

: EAT decreased upper limb spasticity and improved functional recovery at the elbow and wrist. Large-scale and rigorous clinical trials are needed to verify the efficacy of EAT.

Using ultrasound elastography to assess non-invasive, non-pharmacological interventions for musculoskeletal stiffness: a systematic review and meta-analysis

PURPOSE

To evaluate the current evidence regarding the use of ultrasound elastography for assessing non-invasive, non-pharmacological interventions for eliciting changes in musculoskeletal stiffness.

METHODS

A systematic search of MEDLINE, CINAHL, EMBASE, and Web of Science databases was performed in accordance with Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Information on measurement and intervention procedures was extracted. Bias was assessed using Cochrane Risk of Bias or Risk of Bias In Non-randomised Studies of Interventions (ROBINS-I) tools for studies with true or quasi-experimental designs, respectively. Analyses were conducted for adequately powered subgroups based on intervention type, measurement site, and population assessed.

RESULTS

Twenty-one studies were included in the review. Overall risk of bias was low for true experimental studies and moderate for quasi-experimental studies. Subgroup analyses indicated a large overall effect for interventions involving manual physiotherapy and taping/splinting for reducing masseter muscle stiffness in patients with masticatory muscle disorders (g = 1.488, 95% CI = 0.320-2.655, p = 0.013). Analyses for other intervention types and patient groups were underpowered.

CONCLUSION

Ultrasound elastography demonstrates clinical applicability for assessing non-invasive, non-pharmacological interventions for musculoskeletal stiffness. However, the comparative efficacy of these interventions for modulating tissue stiffness remains inconclusive.

Spasticity evaluation and management tools

Spasticity is a complex and often disabling symptom for patients with upper motor neuron syndromes. Although spasticity arises from neurological disease, it often cascades into muscle and soft tissue changes, which may exacerbate symptoms and further hamper function. Effective management therefore hinges on early recognition and treatment. To this end, the definition of spasticity has expanded over time to more accurately reflect the spectrum of symptoms experienced by persons with this disorder. Once identified, clinical and research quantitative assessments of spasticity are hindered by the uniqueness of presentations both for individuals and for specific neurological diagnoses. Objective measures in isolation often fail to reflect the complex functional impact of spasticity. Multiple tools exist to quantitatively or qualitatively assess the severity of spasticity, including clinician and patient-reported measures as well as electrodiagnostic, mechanical, and ultrasound measures. A combination of objective and patient-reported outcomes is likely required to better reflect the burden of spasticity symptoms in an individual. Therapeutic options exist for the treatment of spasticity along a broad spectrum from nonpharmacologic to interventional procedures. Treatment strategies may include exercise, physical agent modalities, oral medications, injections, pumps, and surgery. Optimal spasticity management most often requires a multimodal approach, combining pharmacological management with interventions that match the functional needs, goals, and preferences of the patient. Physicians and other healthcare providers who manage spasticity must be familiarized with the full array of spasticity interventions and must frequently reassess results of treatment to ensure the patient's goals of treatment are met.

Elucidating the mechanisms of post-stroke motor recovery mediated by electroacupuncture using diffusion tensor tractography

Acupuncture has been commonly used for post-stroke patients, and electroacupuncture allows simultaneous application of acupuncture and electrical stimulation. We aimed to elucidate the mechanism of electroacupuncture on post-stroke motor recovery using diffusion tensor tractography. A total of 33 subacute stroke patients were recruited. The control group was subjected to conventional rehabilitation therapy. In contrast, the patients in the experimental group received electroacupuncture treatment for 30 min per session for 4 weeks in addition to the rehabilitation therapy. Fugl-Meyer assessment of the lower extremity (FMA_L), functional ambulation categories (FAC), and the Korean version of modified Barthel index (K-MBI) were used to compare behavioral outcomes between groups. The corticospinal tract (CST) was examined before and after the intervention via diffusion tensor tractography (DTT) to determine the motor recovery mechanism mediated by electroacupuncture. After 4 weeks of intervention, both the control and experimental groups showed a significant improvement with respect to FMA_L, FAC, and K-MBI. The level of improvement in FMA_L, FAC, and K-MBI did not vary significantly between the two groups. However, DTT results showed that the CST fractional anisotropy of the affected side (control: from 0.456 to 0.464, experimental: from 0.459 to 0.512) and its ratio (control: from 89.8 to 90.3, experimental: from 90.2 to 93.3) were significantly different between the two groups (p = 0.032 and p = 0.018). In addition, there were significant differences in the CST axial diffusivity of affected side (control: from 0.783 to 0.877, experimental: from 0.840 to 0.897) and its ratio variation (control: from 87.9 to 100.0, experimental: from 95.7 to 100.7) between the groups (p = 0.003 and p = 0.001). Electroacupuncture played a role in promoting brain plasticity and delaying neural degeneration in subacute period after stroke. Thus, electroacupuncture could be an effective adjuvant therapy in addition to conventional rehabilitation for motor recovery after stroke in a long-term perspective.

Effectiveness and safety of acupuncture for post-stroke spasticity: A systematic review and meta-analysis

Objective

This systematic review and meta-analysis aimed to comprehensively evaluate the effectiveness and safety of acupuncture for post-stroke spasticity.

Methods

Nine electronic databases were searched from their inception to 6 June 2022, to identify randomized-controlled trials (RCTs) that investigated the effectiveness and safety of acupuncture for post-stroke spasticity. Two reviewers independently screened the studies, extracted the data, assessed the risk of bias. The reporting quality of interventions in controlled trials of acupuncture was evaluated using Revised Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA). The RevMan 5.4 and R 4.2.0 software were used for statistical analysis.

Results

A total of 88 eligible studies were included, involving 6,431 individuals. The pooled data demonstrated that acupuncture combined with conventional rehabilitation (CR) was superior to CR in reducing the Modified Ashworth Scale (MAS) score (standardized mean difference [SMD] = -0.73; 95% CI = -0.83 to -0.63; I 2 = 65%; low certainty of evidence). The favorable results were also observed in comparisons of acupuncture vs. CR (SMD = -0.22, 95% CI = -0.36 to -0.07; I 2 = 49%; moderate certainty of evidence). Subgroup analysis showed that acupuncture treatment with a frequency of once or twice a day was more effective than CR. In addition, the antispasmodic effect of acupuncture treatment increased with more sessions. Four studies explicitly reported slight acupuncture-related adverse events.

Conclusion

Acupuncture could be recommended as adjuvant therapy for spasticity after stroke. However, due to the high risk of bias and heterogeneity of the included studies, the effectiveness of acupuncture for post-stroke spasticity remains to be confirmed.

Acupuncture and Traditional Chinese Herbal Medicine Integrated With Conventional Rehabilitation for Post-stroke Functional Recovery: A Retrospective Cohort Study

Background

Stroke leads to tremendous impacts on patients and the healthcare system. It is crucial to explore the potential management of rehabilitation. Acupuncture and traditional Chinese herbal medicine (TCHM) integrated with conventional rehabilitation benefit post-stroke functional recovery.

Methods

We retrospectively reviewed the medical records of all patients included in the Integrated Traditional Chinese-Western Medicine care program for stroke (ITCWM-stroke care program) in 2019 in Taipei Tzu Chi Hospital to investigate the effects of acupuncture and TCHM integrated with conventional rehabilitation on National Institutes of Health Stroke Scale (NIHSS) and Barthel Index (BI) scores before and after the program.

Results

A total of 255 stroke inpatients were retrieved and divided into acupuncture and acupuncture + TCHM group by hemorrhagic and ischemic stroke types, respectively. All the patients were recruited in the program at the early subacute phase after stroke onset. Of the hemorrhagic and ischemic stroke subjects, the NIHSS and BI total scores were significantly improved in the acupuncture and acupuncture + TCHM groups. The subgroup analysis results showed that in subjects with a baseline BI score ≤ 40, the acupuncture + TCHM group significantly improved BI total score better than the acupuncture group in both hemorrhagic (p < 0.05) and ischemic (p < 0.05) stroke subjects.

Conclusion

Acupuncture and TCHM integrated with conventional rehabilitation significantly improve stroke patients’ functional recovery at the early subacute phase. Acupuncture + TCHM contributes to better activities of daily living (ADL) improvements in stroke patients with a baseline BI score ≤ 40. We suggest integrating acupuncture and TCHM into the post-stroke rehabilitation strategy, especially for stroke patients with poor ADL function.

Invasive Physiotherapy as a Treatment of Spasticity: A Systematic Review

Introduction

Nowadays, a set of novel physiotherapy techniques have emerged, in which the physical agent used to try to reduce spasticity is applied percutaneously, specifically, through the patient’s skin. The aim of this work is to encompass all the invasive techniques used in spasticity in a single article, updating the existing bibliography.

Methodology

A systematic review was carried out between December 2020 and April 2021 in the Web of Science, Scopus and PubMed databases, selecting the clinical trials that used acupuncture, electroacupuncture or dry needling as a treatment for spasticity. Sixteen clinical trials were included, summarizing all the study characteristics and the outcome measures, at last the evidence was described for their results.

Results

Most of the studies find a difference of significant decrease in spasticity between the subjects of the experimental groups. Only four studies found no significant changes in spasticity. All the studies are carried out together with the conventional physiotherapy treatment in spasticity.

Conclusion

Treatment with invasive physiotherapy, combined with conventional physiotherapy, seems to have positive effects in reducing spasticity, although more studies are needed to improve the heterogeneity of the interventions and to assess their long-term effectiveness.

Acupuncture Therapy on Patients with Flaccid Hemiplegia after Stroke: A Systematic Review and Meta-Analysis

Background

Acupuncture is a commonly used complementary treatment for flaccid hemiplegia caused by stroke, but evidences from previous randomized trials were inconclusive. The purpose of this study was to evaluate the efficacy and safety of acupuncture in a comprehensive synthesis.

Methods

We searched literature from eight databases from their inception to December 2020. We included randomized controlled trials of acupuncture for the treatment of flaccid hemiplegia following stroke. The meta-analysis was carried out using Review Manager 5.3 and Stata 16.0. The main indicator was the Fugl-Meyer Assessment scale. The modified Barthel Index scale, Quality Of Life Assessment scale, Mini-Mental State Examination scale, Berg Balance Scale, Neurological Deficit Assessment scale, and the treatment effective rate were used to measure the secondary indicators. Adverse events from individual studies were used to determine safety.

Results

Our search returned 7624 records, of which 27 studies involving a total of 1,293 patients fulfilled our inclusion criteria. To be noted, our results indicated that significant improvements in the scores of the primary indicator showed better clinical scores among the three groups with acupuncture than without acupuncture: acupuncture compared with rehabilitation, 13.53 (95% CI 11.65–14.41, P < 0.01); acupuncture plus rehabilitation compared with rehabilitation, 9.84 (95% CI 6.45–13.24, P < 0.01, I² = 98%); and acupuncture plus Western medicine therapy compared with Western medicine, 16.86 (95% CI 15.89–17.84, P < 0.01, I² = 38%), and the secondary indicators showed the same tendency.

Conclusion

Acupuncture was effective and safe in the patients with flaccid hemiplegia after stroke, although there was high heterogeneity between studies.

Comparative Analysis of the Effect of Low-Frequency Repeated Transcranial Magnetic Stimulation and Extracorporeal Shock Wave on Improving the Spasm of Flexor after Stroke

Poststroke spasticity (PSS) patients with muscle spasticity are effectively relieved by low-frequency repetitive transcranial magnetic stimulation (rTMS) or extracorporeal shock wave treatment (ESWT). However, there are relatively few reports about the difference in the efficacy of rTMS and ESWT for PSS. In this study, we examined and recorded the levels of UE motor section of the Fugl–Meyer Motor Assessment Scale (FMA-UE), myoelectric signal time-domain range integral values (iEMG), Modified Ashworth Scale (MAS), and Modified Barthel Index (MBI) before and after treatment to observe the differences in treatment effects between rTMS and ESWT in patients with PSS. 66 patients with PSS were enrolled in the study and signed an informed consent form, and the study was approved by the Ethics Committee of the First Hospital of Soochow University (2019008). The patients were divided into rTMS group, ESWT group, and regular group according to the random number table method, and there were 22 patients in each group. The rTMS group and ESWT group were treated with rTMS and ESWT on the basis of conventional treatment in the regular group, 5 times a week, and the total treatment time was 4 weeks. The results of the study showed that iEMG, MAS, FMA-UE, and MBI scores in the rTMS, ESWT, and regular groups were significantly ameliorated after treatment compared with those before treatment. The efficacy of the ESWT group was significantly better than in the regular group and slightly better than in the rTMS group, as shown by the iEMG, MAS, FMA-UE, and MBI scores, and the iEMG score of the ESWT group was significantly better than the rTMS group, while there were no significant differences in other indexes. The FMA-UE and MBI scores in the rTMS group were significantly better than those in the regular group after treatment in the rTMS group; however, the comparison between iEMG and MAS scores was not statistically significant. It can be seen that both rTMS and ESWT can alleviate upper limb flexor spasm, improve upper limb motor function, and improve activities of daily living in patients with PSS. Among them, ESWT has better antispasmodic effect and better short-term treatment effect.

Zakaria H, M. Ragab W, Al Awaji NN, Y. Elzanaty M, R. Elserougy H. Therapeutic Efficacy of Transcutaneous Electrical Nerve Stimulation Acupoints on Motor and Neural Recovery of the Affected Upper Extremity in Chronic Stroke: A Sham-Controlled Randomized Clinical Trial

Inability to use the affected upper extremity (UE) in daily activities is a common complaint in stroke patients. The somatosensory system (central and peripheral) is essential for brain reorganization and plasticity. Neuromuscular electrical stimulation is considered an effective modality for improving UE function in stroke patients. The aim of the current study was to determine the therapeutic effects of transcutaneous electrical nerve stimulation (TENS) acupoints on cortical activity and the motor function of the affected UE in chronic stroke patients. Forty male and female patients diagnosed with stroke agreed to join the study. They were randomly assigned to group 1 (G1) and group 2 (G2). G1 received task-specific training (TST) and sham electrical stimulation while G2 received TST in addition to TENS acupoints. Session duration was 80 min. Both groups received 18 sessions for 6 successive weeks, 3 sessions per week. Evaluation was carried out before and after completion of the treatment program. Outcome measures used were the Fugl-Meyer Assessment of the upper extremity (FMA-UE) and the box and block test (BBT) as measures of the motor function of the affected UE. Brain activity of the motor area (C3) in the ipsilesional hemisphere was measured using a quantitative electroencephalogram (QEEG). The measured parameter was peak frequency. It was noted that the motor function of the affected UE improved significantly post-treatment in both groups, while no significant change was reported in the FMA-UE and BBT scores post-treatment in either G1 or G2. On the other hand, the activity of the motor area C3 improved significantly in G2 only, post-treatment, while G1 showed no significant improvement. There was also significant improvement in the activity of the motor area (C3) in G2 compared to G1 post-treatment. The results of the current study indicate that TST only or combined with TENS acupoints can be considered an effective method for improving motor function of the affected UE in chronic stroke patients, both being equally effective. However, TST combined with TENS acupoints proved better in improving brain plasticity in chronic stroke patients.

The Effectiveness of Acupuncture for Dysphagia after Stroke: A Systematic Review and Meta-Analysis

Objectives

This study reviewed and evaluated existing evidence of the efficacy of acupuncture as a clinical treatment for dysphagia after stroke.

Methods

Five English and four Chinese databases were searched from inception to March 2020. All randomized controlled trials (RCTs) incorporating acupuncture or acupuncture combined with other interventions for the treatment of dysphagia after stroke were enrolled. All data were independently assessed and extracted by two authors. The bias risk assessment recommended by the Cochrane Collaboration's tool was used to assess the quality of the selected studies. This meta-analysis was conducted by using RevMan 5.3. Pooled analyses were calculated by the mean difference (MD) and 95% confidence interval (CI). Heterogeneity was assessed by the I² test.

Results

Thirty-five studies involving 3024 patients were analyzed. The meta-analysis showed that the therapeutic efficacy of acupuncture combined with other interventions was better than that of the control group for the standardized swallowing assessment (SSA) score (MD = −3.78, 95% CI: −4.64 to −2.91, P < 0.00001), Ichiro Fujishima rating scale (IFRS) score (MD = 1.68, 95% CI: 1.16 to 2.20, P < 0.00001), videofluoroscopic swallowing study (VFSS) score (MD = 2.26, 95% CI: 1.77 to 2.74, P < 0.00001), and water swallowing test (WST) score (MD = −1.21, 95% CI: −1.85 to −0.57, P= 0.0002). In studies reporting adverse effects, no serious outcome from an adverse event was confirmed.

Conclusion

This systematic review indicated that acupuncture could be an effective therapy for treating dysphagia after stroke although stricter evaluation standards and rigorously designed RCTs are needed.

Electroacupuncture for Poststroke Spasticity: Results of a Pilot Pragmatic Randomized Controlled Trial

CONTEXT

People with spasticity that occurred between 30 days and one year after stroke onset with a baseline Modified Ashworth Scale (MAS) ≥1.

OBJECTIVES

To determine the practicality of a pragmatic parallel-group open-labeled randomized controlled trial and to collect preliminary data of effectiveness and safety of electroacupuncture (EA) for poststroke spasticity.

METHODS

Eligible participants were randomly allocated to the intervention group (EA plus usual care) or the control group (usual care alone) at a 1:1 ratio with block sizes of six. Participants received EA three times a week for four weeks, then were followed up for another four weeks. Participants' retention and adherence in the trial were assessed to determine the practicality of trial design. Clinical outcome measures were the change scores of MAS, Fugl-Meyer Assessment of motor performance and Barthel Index, and adverse events.

RESULTS

Seventy-two people were screened for eligibility, and 30 of them were recruited and randomized. At the end, 25 participants followed the trial protocol and were included in our final data analyses using an intention-to-treat approach. No significant between-group difference was detected for the change scores of MAS, Fugl-Meyer Assessment, or Barthel Index at the end of treatment or end of follow-up. Eighteen participants reported 37 adverse events, but none of the participants was deemed related to EA.

CONCLUSION

It is feasible to conduct a full-scale trial to precisely evaluate the effectiveness and safety of EA for treating poststroke spasticity; however, longer treatment and follow-up phases should be considered in the full-scale trial.

Acupoint catgut embedding for the treatment of sciatica: A protocol for a systematic review

BACKGROUND

Sciatica is a common and frequent peripheral neuropathic pain disease, which causes a great burden on peoples life. Recently, acupoint catgut embedding (ACE) has been widely applied for treating sciatica in China, however, there is no enough evidence to prove the efficiency and safety of ACE for sciatica. Our study aims to evaluate the efficiency and safety of ACE for sciatica.

METHODS AND ANALYSIS

Searches of the Cochrane Library, PubMed, Springer Medline, EMBASE, China National Knowledge Infrastructure (CNKI), Wan-Fang Data (WANFANG), Chinese Biomedical Literature Database (CBM), and Chinese Scientific Journal Database (VIP databases) will be performed from inception to November 2020. The main outcomes are the pain intensity and the whole efficiency assessment. The secondary outcomes will include Oswestry Disability Index (ODI), life quality, physical examination, and adverse events. Two reviewers will separately conduct the study selection, data extraction and study quality assessments. RevMan 5.3 software will be used for meta-analysis.

RESULTS

This study will provide an evidence-based review of acupoint catgut embedding therapy for sciatica according to the pain intensity, the whole efficiency assessment, life quality, DOI index and adverse events.

CONCLUSIONS

This systematic review will present the current evidence for acupoint catgut embedding therapy for sciatica.

Acupoint catgut embedding for obesity: A protocol of systematic review

BACKGROUND

Obesity is a chronic metabolic disease in which patients are overweight due to the excessive accumulation of fat in the body. As a subtype of acupuncture, catgut embedding at acupoints has increased in clinical application for obesity. The aim of this study is to evaluate the effectiveness and safety of acupoint catgut embedding therapy for simple obesity.

METHODS AND ANALYSIS

Electronic searches of the Cochrane Library, PubMed, Springer Medline, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Wan-Fang Data (WANFANG), Chinese Biomedical Literature Database (CBM), and Chinese Scientific Journal Database (VIP databases) will be performed. The Chinese Clinical Trial Registry Center and the ClinicalTrials.gov registry will also be searched for ongoing trials. Databases will be searched from inception to August 2020.Randomized controlled clinical trials (RCTs) will be included if acupoint catgut embedding was evaluated as the sole treatment (diet or exercise therapy as the control group will be allowed) for simple obesity. The primary outcomes will consist of the improvement rate and reduction in body weight (BW). The secondary outcomes will include body mass index (BMI), waist circumference (WC), fat percentage (F %) and adverse effects. Two reviewers will undertake the study selection, data extraction and assessments of study quality. After screening the studies, the quality of the included studies will be assessed according to the quality criteria specified by the Cochrane Handbook for Systematic Reviews of Interventions (version 5.1.0). Meta-analysis will be performed by RevMan 5.3 software.

[Acupuncture in the prevention and treatment of stroke: a review of foreign studies]

Acupuncture has been recommended by the World Health Organization (WHO) as an alternative and complementary method for treating stroke and a way to increase the effectiveness of rehabilitation. The data available in the literature suggest that acupuncture has a beneficial effect on the status of patients with stroke. The mechanism of action of acupuncture for stroke includes the following components: 1) stimulation of neurogenesis and cell proliferation in the CNS; 2) regulation of cerebral blood flow; 3) antiapoptosis; 4) regulation of neurotransmitters; 5) improvement of the neuronal synaptic function, stimulation of long-term potentiation; 6) stimulation of neuroplasticity; and 7) decrease in blood-brain barrier permeability. Acupuncture has been proven to have a positive impact on the restoration of stroke-related dysfunctions, such as motor disorders, spasticity, cognitive impairment, and dysphagia. The most commonly used acupuncture points for the treatment of motor disorders are GV20, GB20, LI4, ST36, SP6, LI11, GB39, and motor scalp area; those for the treatment of cognitive dysfunction are GV20 and EX-HN-1, and those for the treatment of dysphagia are GV20, GV16, and CV23. A review of the literature indicates that studies of the clinical potential of acupuncture in the treatment of complications and the prevention of stroke are insufficient. It is assumed that the international community's recent interest in acupuncture methods used in the treatment of stroke will lead to the emergence of new studies and publications.

The Therapeutic Effect of Electroacupuncture Therapy for Ischemic Stroke

Electroacupuncture (EA) stimulation is a supplementary therapy and commonly applied in treatment of ischemic stroke in clinic. Stroke is an important cause of long-term disability in individuals in both developing and developed countries. In our review, we show the application of EA stimulation for apoplectic pain, limbs spasticity, blood flow interruption, depression, swallowing dysfunction, aphasia, urinary incontinence, cognition and memory impairment, and constipation following stroke in patients and the related mechanisms in animals. The effectiveness of EA involves with acupoints, intensity, intervals, and duration of intervention for treatment of stroke. The combination of EA and common rehabilitation treatment may exert better effect compared with EA alone. In summary, EA might provide a potential treatment strategy for treating apoplectic patients in clinic.

Dry needling for the management of spasticity, pain, and range of movement in adults after stroke: A systematic review

OBJECTIVE

To summarise the available evidence about the effectiveness of deep dry needling (DN) on spasticity, pain-related outcomes, and range-of-movement (ROM) in adults after stroke.

DESIGN

A computer search of Web of Science, Scopus, Medline, Cochrane Library, Cinahl, and Physiotherapy Evidence Database (PEDro) was conducted. A hand search of the reference lists of the selected studies and other relevant publications was also undertaken. Studies were assessed by two independent reviewers and included if they complied with the following criteria: (1) participants were adults after a stroke, (2) use of DN alone or within a multimodal approach, compared to no intervention or other treatments; (3) assessment of spasticity, pain, or joint ROM as a primary or secondary outcome. We included randomised controlled trials (RCTs), case series, and case reports. Data were extracted using a standardised protocol. The methodological quality of the studies was assessed with the Checklist for Measuring quality.

RESULTS

A total of sixteen studies, 7 of which were RCTs, were selected. All studies generally reported an improvement of spasticity level, pain intensity, and ROM after the use of DN, alone or combined with other interventions, in stroke survivors.

CONCLUSION

The management of adults after stroke with DN may impact positively on spasticity, pain, and ROM. However, there was significant heterogeneity across trials in terms of sample size, control groups, treated muscles, and outcome measures, and a meta-analysis was not feasible. Further research should include proper blinding, sham placebo DN as control intervention, and investigate long-term effects.

Effect of Acupuncture Intervention and Manipulation Types on Poststroke Dysarthria: A Systematic Review and Meta-Analysis

This study aimed to evaluate the effect of acupuncture intervention and manipulation types on poststroke dysarthria. Electronic database, including PubMed, CENTRAL, Scopus, RISS, and CNKI, were searched for randomized controlled trials (RCT), treating dysarthria using acupuncture, speech-language therapy (SLT), and general management (GM), published before April 2019. The number, distribution, intensity, depth, and repetition of acupuncture and bleeding therapy on the sublingual veins were considered as manipulation types. Risk of bias of the included trials was evaluated, and their efficacy was assessed using risk ratio (RR) and the standard mean differences in the Frenchay Dysarthria Assessment and Speech Function Grading, with 95% confidence intervals (CIs).Fifteen RCT trials involving 1453 patients were isolated. Electroacupuncture plus SLT and manual acupuncture plus SLT were more effective than SLT only, respectively (RR = 1.520, 95% CI [1.183-1.952], RR = 1.380, 95% CI [1.281-1.488]). The clinical efficacy of acupuncture plus GM was higher than that of GM alone (RR = 1.165, 95% CI [1.050-1.293]). Meta-ANOVA showed that none of the manipulation types increased the clinical efficacy of acupuncture on dysarthria. The methodological quality was low. In conclusion, our study suggests that the effect of acupuncture on poststroke dysarthria may be maximized when manual acupuncture or electroacupuncture is combined with SLT, irrespective of manipulation types.

Predictors for the use of traditional Chinese medicine among inpatients with first-time stroke: a population-based study

BACKGROUND

Stroke is one of the major causes of death and disability. The treatments that are provided to patients during hospitalization after an acute stroke are very important in stabilizing their medical condition and enabling the recovery of their motor functions. However, limited information is available regarding the use of traditional Chinese medicine (TCM) during hospitalization for first-time stroke patients. The researchers aimed to investigate the factors affecting TCM use and to provide clinicians with comprehensive information on TCM use among first-time stroke inpatients in Taiwan.

METHODS

The researchers collected and analyzed data, including patient characteristics, TCM use, and TCM prescription patterns, from the National Health Insurance Research Database in Taiwan for first-time stroke inpatients between 2006 and 2012.

RESULTS

Among the 89,162 first-time stroke patients, 7455 were TCM users, and 81,707 were TCM nonusers. The predictors for TCM use were as follows: age, 45-64 or < 45 years; men; living in a level 2, 4, or 7 urbanized area; insured amount ≥ 576 USD per month; ischemic stroke; hospitalized for first-time stroke for 8-14 days, 15-28 days, or ≥ 29 days; stroke severity index score 0-9 or 10-19; Charlson-Deyo comorbidity index score 0 or 1-2; hospitalization in a regional or community hospital; receiving rehabilitation; and previous experience with outpatient TCM use. An increase in the number of TCM users was observed from 2006 to 2012. Furthermore, 68.8-79.7% of TCM users used acupuncture only, while 17.8-26.1% used both acupuncture and Chinese herbal medicine.

CONCLUSIONS

An increasing number of first-time stroke patients have been choosing TCM as a complementary treatment during hospitalization. Moreover, TCM use is associated with demographic, clinical, and socioeconomic characteristics. These findings may help clinicians comprehensively understand the trend and the important factors affecting TCM utilization among patients who are hospitalized due to first-time stroke.

Different acupuncture therapies for spastic paralysis after stroke: A protocol for systematic review and network meta-analysis

BACKGROUND

Stroke is emerging as a significant health issue that threatens human health worldwide and as a common sequela of stroke spastic paralysis after stroke (SPAS) has received wide attention. Currently, several systematic reviews have suggested that the commonly used acupuncture therapy (electroacupuncture, fire acupuncture, warm acupuncture, and filiform needle acupuncture) has achieved significant efficacy in the treatment of SPAS. In this study, network meta-analysis will be used to analyze the results of different clinical trials and evaluate the differences in the efficacy of different acupuncture treatments for SPAS.

METHODS

Only randomized controlled trials will be included and all patients were diagnosed as spastic paralysis after stroke. A computer-based retrieval will be conducted at CNKI, WanFang databases, VIP, Sinoed, Pubmed, Embase, Web of Science, and the Cochrane library. The search period limit is from the time the date of database establishment to April 17, 2020. To avoid omissions, we will manually retrieve relevant references and conference papers. The risk of bias in the final included studies will be evaluated based on the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. All data analysis will be conducted by Revman5.3, WinBUGS 1.4.3, and Stata14.2.

RESULTS

This study quantified the effectiveness of each intervention for different outcome indicators. The primary outcomes include the Fugl-Meyer Assessment score, the modified Ashworth scale for the assessment of spasticity, and Barthel Index. The secondary outcomes include clinical effectiveness and adverse reactions.

CONCLUSION

It will provide evidence-based medical evidence for clinicians to choose more effective acupuncture therapy for SPAS.

Standardization of rehabilitation program for post-apoplectic limb spasm treated by Tongjing Tiaoxing tuina and scalp acupuncture with physical therapy

BACKGROUND

Tong Jing Tiao Xing tuina (TJTX) is a Chinese massage method. Excising with scalp acupuncture (ESA) is a treatment combining scalp electroacupuncture with physical therapy (PT), and yinao fujian formula (YNFJ) is a Chinese oral herbal granule medicine. The combination of the 3 methods is called the "Zhishen Tiaoxing" (ZSTX) rehabilitation program, which is used as an alternative of limb spasm after stroke. There is little available evidence demonstrating its safety and efficacy.

METHODS

This will be a subject-blind, randomized controlled trial conducted in 3 medical centers. It will strictly follow the Standards for Reporting Interventions in Clinical Trials of Acupuncture, 2010. We will recruit 316 patients with limb spasm after stroke, 200 from the Affiliated Hospital of Changchun University of Chinese Medicine, Changchun, China, 80 from the Second Affiliated Hospital of Heilongjiang University of Chinese medicine, Harbin, China, and 36 from Huashan Hospital of Fudan University, Shanghai, China. A block randomization sequence stratified by centers will be generated using SAS Version 9.2 software (SAS Institute, Cary, NC, USA), which was performed at the Guangdong Provincial Hospital of Chinese Medicine's Key Unit of Methodology in Clinical Research. The treatment group is treated with TJTX (once a day), ESA (once a day), and oral YNFJ (twice a day). The control group will be treated with PT. Two groups of patients will be treated 5 sessions a week for 4 weeks, and there will be 6-month follow-up. The outcome evaluators will be blinded to patient grouping. The primary outcome will be modified Ashworth scales. The secondary outcome indexes will be the simplified Fugl-Meyer assessment scale, surface electromyogram root mean square value, modified Barthel index, stroke-specific quality of life scale, health scale of traditional Chinese medicine, visual analogue scale (VAS), and the Hamilton depression scale.

DISCUSSION

The Randomized Controlled Trial (RCT) mainly aim to evaluate the effectiveness and safety of traditional Chinese medicine rehabilitation program, by comparing the treatment of ZSTX with the PT for the treatment of limb spasm after stroke.

Acupuncture for poststroke spasticity: A protocol of a systematic review and meta-analysis

INTRODUCTION

Spasticity is the most common complication after stroke, which is the main obstacle in the recovery of motor function. Spasticity seriously affects the quality of life and brings a heavy burden to families and society. Acupuncture is an effective method for stroke. However, whether acupuncture is effective for poststroke spasticity is still unknown. The purpose of this systematic review (SR) is to evaluate the effectiveness and safety of acupuncture for poststroke spasticity.

METHODS AND ANALYSIS

We will search the following databases from inception to July 2019: China Biology Medicine (CBM), China National Knowledge Infrastructure (CNKI), Wan Fang Data, the Chinese Science and Technology Periodical Database (VIP), PubMed, Embase, The Cochrane Library, and Web of Science. All relevant randomized controlled trials (RCTs) utilizing acupuncture for poststroke spasticity will be included. The primary outcome is the modified Ashworth scale. Secondary outcomes include composite spasticity scale, clinic spasticity index, electromyographic activity, Hoffmann reflex activity, or other spasticity-related outcomes. Study selection, data extraction, and quality assessment will be performed independently by 2 reviewers. Assessment of risk of bias and data synthesis will be conducted using Review Manager V5.3 software.

ETHICS AND DISSEMINATION

The ethical approval is not required since SR is based on published studies. The results of this SR will be published in a peer-reviewed scientific journal according to the Preferred Reporting Item for Systematic Review and Meta-analysis (PRISMA) guidelines.

Effect of Tui Na on upper limb spasticity after stroke: a randomized clinical trial

Objective

To investigate the efficacy and safety of Tui Na for treating spasticity of the upper limbs of stroke patients.

Design

A prospective, multicenter, blinded, randomized controlled intervention study.

Subjects

Stroke patients with upper limb spasticity who were treated between December 2013 and February 2017 in 16 participating institutions in China were randomly assigned to receive either Tui Na plus conventional rehabilitation (Tui Na group, n = 222,) or conventional rehabilitation only (control group, n = 222).

Methods

Eligible adult patients (aged 18–75 years) were enrolled 1–12 months after stroke and randomly allocated in a 1:1 ratio to the two groups. Outcome assessors were blinded to treatment allocation. Muscle tone in the spastic muscles was evaluated using the Modified Ashworth Scale (MAS), and the primary endpoint was the change in MAS score over 4 weeks of treatment.

Results

Among patients who had experienced stroke 1–3 months before treatment, the Tui Na group experienced significantly greater reductions in MAS scores for three muscle groups than did the control group after 4 weeks of treatment. These improvements were sustained at the 3‐ and 6‐month follow‐ups. However, among patients who suffered from stroke 4–6 months and 7–12 months before treatment, the change in MAS with treatment did not differ significantly between those who did and those who did not receive Tui Na. No Tui Na‐related adverse events during treatment were reported the groups.

Conclusion

Tui Na was effective and safe for alleviating poststroke spasticity within 1–3 months after stroke onset.

Interventions for treating urinary incontinence after stroke in adults

BACKGROUND

Urinary incontinence can affect 40% to 60% of people admitted to hospital after a stroke, with 25% still having problems when discharged from hospital and 15% remaining incontinent after one year.This is an update of a review published in 2005 and updated in 2008.

OBJECTIVES

To assess the effects of interventions for treating urinary incontinence after stroke in adults at least one-month post-stroke.

SEARCH METHODS

We searched the Cochrane Incontinence and Cochrane Stroke Specialised Registers (searched 30 October 2017 and 1 November 2017 respectively), which contain trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, CINAHL, ClinicalTrials.gov, WHO ICTRP and handsearched journals and conference proceedings.

SELECTION CRITERIA

We included randomised or quasi-randomised controlled trials.

DATA COLLECTION AND ANALYSIS

Two review authors independently undertook data extraction, risk of bias assessment and implemented GRADE.

MAIN RESULTS

We included 20 trials (reporting 21 comparisons) with 1338 participants. Data for prespecified outcomes were not available except where reported below.Intervention versus no intervention/usual careBehavioural interventions: Low-quality evidence suggests behavioural interventions may reduce the mean number of incontinent episodes in 24 hours (mean difference (MD) -1.00, 95% confidence interval (CI) -2.74 to 0.74; 1 trial; 18 participants; P = 0.26). Further, low-quality evidence from two trials suggests that behavioural interventions may make little or no difference to quality of life (SMD -0.99, 95% CI -2.83 to 0.86; 55 participants).Specialised professional input interventions: One trial of moderate-quality suggested structured assessment and management by continence nurse practitioners probably made little or no difference to the number of people continent three months after treatment (risk ratio (RR) 1.28, 95% CI 0.81 to 2.02; 121 participants; equivalent to an increase from 354 to 453 per 1000, 95% CI 287 to 715).Complementary therapy: Five trials assessed complementary therapy using traditional acupuncture, electroacupuncture and ginger-salt-partitioned moxibustion plus routine acupuncture. Low-quality evidence from five trials suggested that complementary therapy may increase the number of participants continent after treatment; participants in the treatment group were three times more likely to be continent (RR 2.82, 95% CI 1.57 to 5.07; 524 participants; equivalent to an increase from 193 to 544 per 1000, 95% CI 303 to 978). Adverse events were reported narratively in one study of electroacupuncture, reporting on bruising and postacupuncture abdominal pain in the intervention group.Physical therapy: Two trials reporting three comparisons suggest that physical therapy using transcutaneous electrical nerve stimulation (TENS) may reduce the mean number of incontinent episodes in 24 hours (MD -4.76, 95% CI -8.10 to -1.41; 142 participants; low-quality evidence). One trial of TENS reporting two comparisons found that the intervention probably improves overall functional ability (MD 8.97, 95% CI 1.27 to 16.68; 81 participants; moderate-quality evidence).Intervention versus placeboPhysical therapy: One trial of physical therapy suggests TPTNS may make little or no difference to the number of participants continent after treatment (RR 0.75, 95% CI 0.19 to 3.04; 54 participants) or number of incontinent episodes (MD -1.10, 95% CI -3.99 to 1.79; 39 participants). One trial suggested improvement in the TPTNS group at 26-weeks (OR 0.04, 95% CI 0.004 to 0.41) but there was no evidence of a difference in perceived bladder condition at six weeks (OR 2.33, 95% CI 0.63 to 8.65) or 12 weeks (OR 1.22, 95% CI 0.29 to 5.17). Data from one trial provided no evidence that TPTNS made a difference to quality of life measured with the ICIQLUTSqol (MD 3.90, 95% CI -4.25 to 12.05; 30 participants). Minor adverse events, such as minor skin irritation and ankle cramping, were reported in one study.Pharmacotherapy interventions: There was no evidence from one study that oestrogen therapy made a difference to the mean number of incontinent episodes per week in mild incontinence (paired samples, MD -1.71, 95% CI -3.51 to 0.09) or severe incontinence (paired samples, MD -6.40, 95% CI -9.47 to -3.33). One study reported no adverse events.Specific intervention versus another interventionBehavioural interventions: One trial comparing a behavioural intervention (timed voiding) with a pharmacotherapy intervention (oxybutynin) contained no useable data.Complementary therapy: One trial comparing different acupuncture needles and depth of needle insertion to assess the effect on incontinence reported that, after four courses of treatment, 78.1% participants in the elongated needle group had no incontinent episodes versus 40% in the filiform needle group (57 participants). This trial was assessed as unclear or high for all types of bias apart from incomplete outcome data.Combined intervention versus single interventionOne trial compared a combined intervention (sensory motor biofeedback plus timed prompted voiding) against a single intervention (timed voiding). The combined intervention may make little or no difference to the number of participants continent after treatment (RR 0.55, 95% CI 0.06 to 5.21; 23 participants; equivalent to a decrease from 167 to 92 per 1000, 95% CI 10 to 868) or to the number of incontinent episodes (MD 2.20, 95% CI 0.12 to 4.28; 23 participants).Specific intervention versus attention controlPhysical therapy interventions: One study found TPTNS may make little or no difference to the number of participants continent after treatment compared to an attention control group undertaking stretching exercises (RR 1.33, 95% CI 0.38 to 4.72; 24 participants; equivalent to an increase from 250 to 333 per 1000, 95% CI 95 to 1000).

AUTHORS' CONCLUSIONS

There is insufficient evidence to guide continence care of adults in the rehabilitative phase after stroke. As few trials tested the same intervention, conclusions are drawn from few, usually small, trials. CIs were wide, making it difficult to ascertain if there were clinically important differences. Only four trials had adequate allocation concealment and many were limited by poor reporting, making it impossible to judge the extent to which they were prone to bias. More appropriately powered, multicentre trials of interventions are required to provide robust evidence for interventions to improve urinary incontinence after stroke.

Novel Treatment Using Intravenous Dantrolene Sodium for Postoperative Exacerbated Spasticity in Multiple Sclerosis: A Case Report

Patients with upper motor neuron disease, such as multiple sclerosis, can present with severe spasticity in the perioperative period. In most cases, this can be managed with a combination of preoperative oral medications, regional or neuraxial anesthetic techniques, and intravenous muscle relaxants. We describe the clinical presentation of a patient with multiple sclerosis and the successful use of intravenous dantrolene sodium postoperatively for the treatment of exacerbated spasticity refractory to traditional management.

Overview of Treatment Guidelines and Clinical Practical Guidelines That Recommend the Use of Acupuncture: A Bibliometric Analysis

INTRODUCTION

As positive evidence emerges for the use of an intervention to treat a health problem, the intervention gradually becomes incorporated into treatment guidelines (TGs) or clinical practice guidelines (CPGs) that are related to that health problem. To assess whether this general hypothesis can apply to acupuncture, 96 health problems were identified for which positive conclusions in systematic reviews and meta-analyses regarding the effectiveness of acupuncture have been made and then searched for TGs or CPGs that have recommended the use of acupuncture.

METHODS

Through August 31, 2017, searches were performed in relevant medical databases and Google using "treatment guideline," "clinical practice guideline," and the names of the 96 medical conditions as search terms. A "snow-balling" search approach was adopted. All positive recommendations were added into the registry.

RESULTS

A total of 1311 publications were found that recommended using acupuncture published between 1991 and 2017. The number per year reached 50 in 2005 and 100 in 2009. In addition, 2189 positive recommendations were found for the use of acupuncture. Of these, 1486 were related to 107 pain indications and 703 were related to 97 nonpain indications. These recommendations were made by a wide range of groups, such as government health institutions, national guideline, and medical specialty groups. The recommendations came from around the world but were especially abundant in North America, Europe, and Australasia.

DISCUSSION AND CONCLUSION

Considerably more recommendations were found for the use of acupuncture than are known within the acupuncture or medical communities. A trend by year was also found; a rise in the number of positive statements about acupuncture was typically followed by a rise in the number of recommendations of acupuncture. Thus, the recommendations followed the emergent evidence for acupuncture. Better implementation plans need to be developed for the CPG/TG recommendations about acupuncture to be more effective/efficient.

Spinal Cord Injury: How Could Acupuncture Help?

Spinal cord injury (SCI) is one of the most common causes of death and disability worldwide, and it can result in both permanent disability and serial complications in patients. Research shows that patients with SCI complications are often interested in acupuncture for symptomatic relief. Therefore, the issue of physicians advising their patients regarding the use of acupuncture to alleviate SCI complications becomes pertinent. We review and summarize two types of relevant publications: (1) literature concerning acupuncture for SCI and its complications and (2) underlying mechanisms of acupuncture therapy for SCI. Clinical trials and reviews have suggested that acupuncture effectively manages a range of post-SCI complications, including motor and sensory dysfunction, pain, neurogenic bowel and bladder, pressure ulcers, spasticity, and osteoporosis. The effect of acupuncture on post-SCI orthostatic hypotension and sexual dysfunction remains unclear. Decreased oxidative stress, inhibition of inflammation and neuronal apoptosis, regulation of the expression and activity of endogenous biological mediators, and increased regenerative stem cell production are the possible mechanisms of acupuncture therapy for SCI. Although many limitations have been reported in previous studies, given the evidence for the efficacy of acupuncture, we recommend that physicians should support the use of acupuncture therapy for SCI complications.

Electroacupuncture for poststroke spasticity (EAPSS): protocol for a randomised controlled trial

INTRODUCTION

Spasticity is a common complication of stroke. Current therapies for poststroke spasticity (PSS) have been reported to be associated with high costs, lack of long-term benefit and unwanted adverse events (AEs). Electroacupuncture (EA) has been used for PSS, however, its efficacy and safety is yet to be confirmed by high-quality clinical studies. This study is designed to evaluate the add-on effects and safety profile of EA when used in combination with usual care (UC).

METHODS AND ANALYSIS

This study is a parallel group randomised controlled trial. A total of 136 participants will be included and randomly assigned to either the treatment group (EA plus UC) or the control group (UC alone). Prior to the main trial, a pilot study involving 30 participants will be conducted to assess the feasibility of the trial protocol. EA will be administered by registered acupuncturists for 20min to 30 min, three times per week for 4 weeks. The primary outcome measure (Modified Ashworth Scale) and secondary outcome measures (Fugl-Meyer Assessment and Barthel Index) will be evaluated at baseline, the end of treatment (week 4) and the end of follow-up (week 8). AEs will be monitored, recorded and reported, and their causality will be explored.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the ethics committees of Guangdong Provincial Hospital of Chinese Medicine and RMIT University in December 2016. The results will be disseminated in a peer-reviewed journal, and PhD theses and might be presented at international conferences.

Longitudinal Brain Functional Connectivity Changes of the Cortical Motor-Related Network in Subcortical Stroke Patients with Acupuncture Treatment

In clinical practice, the effectiveness of the rehabilitation therapy such as acupuncture combining conventional Western medicine (AG) on stroke people's motor-related brain network and their behaviors has not been systematically studied. In the present study, seventeen adult ischemic patients were collected and divided into two groups: the conventional Western medicine treatment group (CG) and the AG. The neurological deficit scores (NDS) and resting-state functional MRI data were collected before and after treatment. Compared with the CG patients, AG patients exhibited a significant enhancement of the percent changes of NDS from pre- to posttreatment intervention. All patients showed significant changes of functional connectivity (FC) between the pair of cortical motor-related regions. After treatment, both patient groups showed a recovery of brain connectivity to the nearly normal level compared with the controls in these pairs. Moreover, a significant correlation between the percent changes of NDS and the pretreatment FC values of bilateral primary motor cortex (M1) in all patients was found. In conclusion, our results showed that AG therapy can be an effective means for ischemic stroke patients to recover their motor function ability. The FC strengths between bilateral M1 of stroke patients can predict stroke patients' treatment outcome after rehabilitation therapy.

An Investigation of the Use of Traditional Chinese Medicine and Complementary and Alternative Medicine in Stroke Patients

This study aimed to investigate the use of traditional Chinese medicine and complementary and alternative medicine in stroke patients in Taiwan. Chinese herbal medicine, massage, acupuncture, natural products, and exercise were widely used among stroke patients. Integrating safe and effective traditional Chinese medicine and complementary and alternative medicine into conventional therapies is suggested.

Non-pharmacological interventions for spasticity in adults: An overview of systematic reviews

OBJECTIVES

Spasticity causes significant long-term disability-burden, requiring comprehensive management. This review evaluates evidence from published systematic reviews of clinical trials for effectiveness of non-pharmacological interventions for improved spasticity outcomes.

METHODS

Data sources: a literature search was conducted using medical and health science electronic (MEDLINE, EMBASE, CINAHL, PubMed, and the Cochrane Library) databases for published systematic reviews up to 15th June 2017.

DATA EXTRACTION AND SYNTHESIS

two reviewers applied inclusion criteria to select potential systematic reviews, independently extracted data for methodological quality using Assessment of Multiple Systematic Reviews (AMSTAR). Quality of evidence was critically appraised with Grades of Recommendation, Assessment, Development and Evaluation (GRADE).

RESULTS

Overall 18 systematic reviews were evaluated for evidence for a range of non-pharmacological interventions currently used in managing spasticity in various neurological conditions. There is "moderate" evidence for electro-neuromuscular stimulation and acupuncture as an adjunct therapy to conventional routine care (pharmacological and rehabilitation) in persons following stroke. "Low" quality evidence for rehabilitation programs targeting spasticity (such as induced movement therapy, stretching, dynamic elbow-splinting, occupational therapy) in stroke and other neurological conditions; extracorporeal shock-wave therapy in brain injury; transcranial direct current stimulation in stroke; transcranial magnetic stimulation and transcutaneous electrical nerve stimulation for other neurological conditions; physical activity programs and repetitive magnetic stimulation in persons with MS, vibration therapy for SCI and stretching for other neurological condition. For other interventions, evidence was inconclusive.

CONCLUSIONS

Despite the available range of non-pharmacological interventions for spasticity, there is lack of high-quality evidence for many modalities. Further research is needed to judge the effect with appropriate study designs, timing and intensity of modalities, and associate costs of these interventions.

Amyotrophic Lateral Sclerosis: An Acupuncture Approach

Background: Amyotrophic lateral sclerosis (ALS) is an adult onset neurodegenerative disorder that has no curative treatment and is usually fatal. Modern medicine treatment is mostly supportive. Acupuncture has much more to offer by way of symptomatic relief and improving quality of life (QoL). Useful points for the treatment of bulbar paralysis, paralysis of upper and lower extremities, and correction of underlying Disharmony Patterns are discussed and an illustrative case is presented to demonstrate the acupuncture approach for treating ALS. Case: A 55-year-old woman had weakness in her right arm and both legs for 4 months. She also had muscle cramps and clumsiness in the affected limbs, which rapidly progressed in the 4 months prior to presentation. She was diagnosed with ALS, given 50 mg of oral riluzole per day, and told that the condition was fatal. She sought acupuncture and was treated for two courses of 8 weeks each. Results: After acupuncture, this patient's symptomatic relief was near perfect in that she became free from disabling symptoms and is now leading a normal life. Conclusions: Acupuncture can be an effective modality of treatment for ALS, producing symptomatic relief and improving QoL.

Enhanced Functional Connectivity between the Bilateral Primary Motor Cortices after Acupuncture at Yanglingquan (GB34) in Right-Hemispheric Subcortical Stroke Patients: A Resting-State fMRI Study

Increasing neuroimaging researches in stroke rehabilitation had revealed the neural mechanisms of rehabilitation therapy. However, little was known about the neural mechanisms of acupuncture therapy in subcortical stroke patients. The aim of this study was to investigate the changes of functional connectivity (FC) between the bilateral primary motor cortices (M1s) after acupuncture intervention in right subcortical stroke patients. Twenty right-hemispheric subcortical stroke patients and 20 healthy subjects were recruited to undergo one functional magnetic resonance imaging (fMRI) scanning. The scanning consisted of resting-state fMRI before and after needling at Yanglinquan (GB34), and task-evoked fMRI. The most significant active point during the left passive thumb-to-index task was chosen as the seed point. The seed-based FC analysis of the bilateral M1s was performed. Stroke patients revealed decreased FC between the bilateral M1s compared with healthy subjects, and the decreased FC was significantly enhanced after acupuncture at GB34. Acupuncture could increase the intrinsically decreased FC between the bilateral M1s which provided further insight into the neural mechanisms of acupuncture for motor function recovery in stroke patients.

Effect of Electroacupuncture on the NTS is modulated primarily by acupuncture point selection and stimulation frequency in normal rats

Background

The effect of electroacupuncture (EA) is affected by both the acupuncture point selection and the frequency of stimulation. However, little is known regarding acupuncture point and simulation frequency selection. Neuronal activation of the nucleus of the solitary tract (NTS) is one of the important targets of EA for modulating gastrointestinal function. This study investigated the effects of various combinations of EA frequencies and acupuncture points on NTS neurons.

Methods

Rats were randomly divided into normal, 2 Hz EA, 100 Hz EA and the alternate 2/100 Hz EA groups. Then rats in each group were randomly divided into the following two subgroups according to the acupuncture point: ST 36 group and ST 25 group. All the rats underwent electrode implantation surgery. Rats in all EA groups received one treatment with EA (a constant square wave at, 2 Hz,100 Hz or 2/100 Hz frequencies with intensities ranging from 1 to 2 mA), and NTS neuronal activation was recorded before and after EA treatment. Finally, to confirm the effect of EA on the NTS, minimal acupuncture was administered and its effect on NTS was detected.

Results

ST 36 stimulated with 2 Hz EA significantly increased the population of excited NTS neurons and spike frequency. However, ST 36 stimulated with 100 Hz or 2/100 Hz EA produced only a transient effect on the activity of NTS neurons and did not induce any effect on the spike frequency. Furthermore, the excitatory effect of 100 Hz or 2/100 Hz EA on NTS neurons in the ST 36 group was lower than 2 Hz EA at the same point. When applied to ST 25, 2 Hz EA had no significant excitatory effect on NTS neurons or spike frequency. However, 100 Hz EA or 2/100 Hz EA at ST 25 decreased both NTS neuronal excitability and spike frequency. By comparing the effects of different EA combinations, it was shown 2 Hz EA applied to ST 36 had the strongest excitatory effect on NTS neurons, while 100 Hz EA applied to ST 25 had the greatest inhibitory effect. Minimal acupuncture stimulation produced no effect on NTS neurons.

Conclusion

EA’s effects on NTS were mainly affected by the acupuncture point selection, but the frequency of EA also played a role. Different combinations of acupuncture points and frequency selection may lead to different EA effects on NTS neuronal excitability.

Clinical Evaluation of Acupuncture as Treatment for Complications of Cerebrovascular Accidents: A Randomized, Sham-Controlled, Subject- and Assessor-Blind Trial

Background and Purpose. The effect of acupuncture as treatment for poststroke complications is questionable. We performed a randomized, sham-controlled double-blind study to investigate it. Methods. Patients with first-time acute stroke were randomized to receive 24 sessions of either real or sham acupuncture during an eight-week period. The primary outcome measure was change in National Institute of Health Stroke Scale (NIHSS) score. Secondary outcome measures included changes in Barthel Index (BI), Instrumental Activities of Daily Living (IADL), Hamilton Depression Rating Scale (HAM-D), and Visual Analogue Scale (VAS) for pain scores. Results. Of the 52 patients who were randomized to receive acupuncture (n = 28) or placebo (n = 24), 10 patients in the acupuncture group and 9 patients in the placebo group failed to complete the treatment. In total, 18 patients in the acupuncture group and 15 patients in the control group completed the treatment course. Reduction in pain was significantly greater in the acupuncture group than in the control group (p value = 0.04). There were no significant differences in the other measures between the two groups. Conclusions. Acupuncture provided more effective poststroke pain relief than sham acupuncture treatment. However, acupuncture had no better effect on neurological, functional, and psychological improvement.

Electroacupuncture improves neurovascular unit reconstruction by promoting collateral circulation and angiogenesis

Acupuncture at Shuigou (GV26) shows good clinical efficacy for treating stroke, but its mechanism remains poorly understood. In this study, a cerebral infarction model of ischemia/reperfusion injury received electroacupuncture at GV26 (15 Hz and 1 mA, continuous wave [biphasic pulses], for 5 minutes). Electroacupuncture effectively promoted regional cerebral blood flow on the infarct and non-infarct sides, increased infarct lesions, lectin, and number of blood vessels, upregulated von Willebrand factor and cell proliferation marker Ki67 expression, and diminished neurological severity score. These findings confirm that electroacupuncture at GV26 promotes establishment of collateral circulation and angiogenesis, and improves neurological function.
