Traditional Chinese medicine for neck pain and low back pain: a systematic review and meta-analysis

Chuna (or Tuina) Manual Therapy for Musculoskeletal Disorders: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

OBJECTIVE

To review the literature and systematically evaluate the effectiveness of Chuna (or Tuina) manual therapy (C[T]MT) on pain and function for musculoskeletal disorders.

METHODS

We searched 15 English, Chinese, Japanese, and Korean databases using relevant keywords. All randomized controlled trials (RCTs) of C(T)MT for musculoskeletal disorders were considered, and we limited analyses to studies with a low-risk bias for randomization and/or allocation concealment.

RESULTS

Sixty-six RCTs with 6,170 participants were included. One sham-controlled RCT showed that C(T)MT relieved pain more effectively than a sham control (SMD -3.09 [-3.59, -2.59]). For active-controlled RCTs, pooled meta-analysis showed that C(T)MT had statistically significant effects on pain reduction, especially compared to traction (P < 0.00001), drugs (P = 0.04), and physical therapies (P < 0.0001). For functional improvement, combined effects of C(T)MT with drugs (P = 0.04) and traction (P = 0.05) also showed similar positive effects.

CONCLUSIONS

This systematic review suggests that C(T)MT is safe and effective for pain reduction and functional improvement for musculoskeletal diseases; however, the evidence for functional improvement was not as strong as for pain reduction. For future studies, high-quality RCTs such as sham-controlled studies with standardized interventions are needed to provide sufficient evidence on the effects of C(T)MT for musculoskeletal diseases. Protocol registration number is CRD42016038307 04/07/2016.

Non-Specific Low Back Pain

BACKGROUND

For many years, low back pain has been both the leading cause of days lost from work and the leading indication for medical rehabilitation. The goal of the German Disease Management Guideline (NDMG) on nonspecific low back pain is to improve the treatment of patients with this condition.

METHODS

The current update of the NDMG on non-specific low back pain is based on articles retrieved by a systematic search of the literature for systematic reviews. Its recommendations for diagnosis and treatment were developed by a collaborative effort of 29 scientific medical societies and organizations and approved in a formal consensus process.

RESULTS

If the history and physical examination do not arouse any suspicion of a dangerous underlying cause, no further diagnostic evaluation is indicated for the time being. Passive, reactive measures should be taken only in combination with activating measures, or not at all. When drugs are used for symptomatic treatment, patients should be treated with the most suitable drug in the lowest possible dose and for as short a time as possible.

CONCLUSION

A physician should be in charge of the overall care process. The patient should be kept well informed over the entire course of his or her illness and should be encouraged to adopt a healthful lifestyle, including regular physical exercise.

Effectiveness of Acupuncture and Electroacupuncture for Chronic Neck Pain: A Systematic Review and Meta-Analysis

The aim of this systematic review was to assess evidence from randomized controlled trials (RCTs) on the effectiveness and safety of acupuncture and electroacupuncture in patients with chronic neck pain. We searched nine databases including Chinese, Japanese and Korean databases through 30 July 2016. The participants were adults with chronic neck pain and were treated with acupuncture or electroacupuncture. Eligible trials were those with intervention groups receiving acupuncture and electroacupuncture with or without active control, and control groups receiving other conventional treatments such as physical therapy or medication. Outcomes included pain intensity, disability, quality of life (QoL) and adverse effects. For statistical pooling, the standardized mean difference (SMD) and its 95% confidence interval (CI) were calculated using a fixed-effects model. Sixteen RCTs were selected. The comparison of the sole acupuncture group and the active control group did not come out with a significant difference in pain (SMD 0.24, 95% CI [Formula: see text]0.27–0.75), disability (SMD 0.51, 95% CI [Formula: see text]0.01–1.02), or QoL (SMD [Formula: see text]0.37, 95% CI [Formula: see text]1.09–0.35), showing a similar effectiveness of acupuncture with active control. When acupuncture was added into the control group, the acupuncture add-on group showed significantly higher relief of pain in studies with unclear allocation concealment (SMD [Formula: see text]1.78, 95% CI [Formula: see text]2.08–[Formula: see text]1.48), but did not show significant relief of pain in studies with good allocation concealment (SMD [Formula: see text]0.07, 95% CI [Formula: see text]0.26–0.12). Significant relief of pain was observed when the sole electroacupuncture group was compared to the control group or electroacupuncture was added onto the active control group, but a lot of the results were evaluated to have low level of evidence, making it difficult to draw clear conclusions. In the result reporting adverse effects, no serious outcome of adverse event was confirmed. Acupuncture and conventional medicine for chronic neck pain have similar effectiveness on pain and disability when compared solely between the two of them. When acupuncture was added onto conventional treatment it relieved pain better, and electroacupuncture relieved pain even more. It is difficult to draw conclusion because the included studies have a high risk of bias and imprecision. Therefore better designed large-scale studies are needed in the future.

Bilateral anterior shoulder dislocation as a result of manipulation: A case report

RATIONALE

Bilateral anterior shoulder dislocation is clinically rare and has been reported to be related to high-speed sports.

PATIENT CONCERNS

A 76-year-old woman presented with bilateral shoulders pain after traditional Chinese manipulation.

DIAGNOSES

She was diagnosed with bilateral anterior dislocations, and a closed reduction was immediately performed.

INTERVENTION

The patient was referred for rehabilitation 3 days later, and bilateral rotator cuff injuries were identified from musculoskeletal ultrasound. After 4 weeks of physical therapy, the patient's shoulder pain had reduced and the passive ROM was nearly full.

OUTCOMES

At 1-year follow-up, only mild intermittent shoulder pain was noted, and there was no limitation of shoulder ROM.

LESSONS

This case illustrates that patients with acute shoulder injuries who receive proper diagnosis and treatment can achieve good outcomes. Therefore, patients with musculoskeletal disorders should seek qualified specialists for accurate diagnosis and appropriate management.

The effect of cupping therapy for low back pain: A meta-analysis based on existing randomized controlled trials

BACKGROUND

LBP is one of the most common symptoms with high prevalence throughout the world. Conflicting conclusions exist in RCTs on cupping for LBP.

OBJECTIVE

To assess the effects and safety of cupping for the patients with LBP.

METHODS

Pubmed, Cochrane Library databases, and Embase database were electronically researched. RCTs reporting the cupping for the patients with LBP were included. The meta-analysis was conducted using Review Manager software (version 5.3, Nordic Cochrane Centre). The primary outcome was VAS scores. The secondary outcomes included ODI scores, MPPI scores and complications.

RESULTS

Six RCTs were included in this synthesized analysis. The results showed that cupping therapy was superior to the control management with respect to VAS scores (SMD: -0.73, [95% CI: -1.42 to -0.04]; P= 0.04), and ODI scores (SMD: -3.64, [95% CI: -5.85 to -1.42]; P= 0.001). There was no statistical significant difference as regard to MPPI scores. No serious adverse event was reported in the included studies.

CONCLUSIONS

Cupping therapy can significantly decrease the VAS scores and ODI scores for patients with LBP compared to the control management. High heterogeneity and risk of bias existing in studies limit the authenticity of the findings.

Effectiveness and Cost-Effectiveness of Tuina for Chronic Neck Pain: A Randomized Controlled Trial Comparing Tuina with a No-Intervention Waiting List

OBJECTIVE

To evaluate whether tuina is more effective and cost-effective in reducing pain compared to no intervention in patients with chronic neck pain.

DESIGN

Single-center randomized two-armed controlled trial.

SETTING

University outpatient clinic specialized in Integrative Medicine.

SUBJECTS

Outpatients with chronic neck pain were randomly allocated to tuina or no intervention.

INTERVENTION

Six tuina treatments within 3 weeks.

OUTCOME MEASURES

The primary outcome was the mean neck pain intensity during the previous 7 days on a visual analogue scale after 4 weeks (VAS, 0-100 mm, 0 = no pain, 100 = worst imaginable pain). Secondary outcomes included Neck Pain and Disability Scale (NPDS), Neck Disability Index (NDI), health-related quality of life (12-item quality-of-life questionnaire [SF-12]), medication intake, and cost-effectiveness after 4 and 12 weeks. Statistical analysis included analysis of covariance adjusted for baseline values and a full economic analysis from a societal perspective.

RESULTS

Altogether, 92 outpatients were included (46 in both groups, 87% female, mean age 45.4 [standard deviation ±9.7], and mean VAS 57.7 ± 11.5). Tuina treatment led to a clinically meaningful reduction in neck pain intensity (group differences, 4 weeks: -22.8 mm [95% confidence interval, -31.7 to -13.8]; p < 0.001 and 12 weeks: -17.9 mm [-27.1 to -8.8], p < 0.001). No serious adverse events were observed. Total costs as well as quality-adjusted life years (QALYs) did not differ significantly between the groups. When taking group differences into account independently from their statistical significance, costs per QALY gained (incremental cost-effectiveness ratio) would range within a cost-effective area from €7,566 (for costs €10.28 per session) to €39,414 (cost €35 per session).

CONCLUSION

An additional treatment with six tuina sessions over 3 weeks was effective, safe and relatively cost-effective for patients with chronic neck pain. A future trial should compare tuina to other best care options.

Clinical Effects of Laser Acupuncture plus Chinese Cupping on the Pain and Plasma Cortisol Levels in Patients with Chronic Nonspecific Lower Back Pain: A Randomized Controlled Trial

Objectives

Chronic nonspecific lower back pain (LBP) is a common disease. Insufficient data is currently available to conclusively confirm the analgesic effects of laser acupuncture on LBP. This study evaluated the effectiveness of laser acupuncture plus Chinese cupping in LBP treatment.

Methods

Patients with chronic nonspecific LBP were enrolled for a randomized controlled trial and assigned to the laser acupuncture group (laser acupuncture plus Chinese cupping) and control group (sham laser plus Chinese cupping). Laser acupuncture (808 nm; 40 mW; 20 Hz; 15 J/cm²) and Chinese cupping were applied on the Weizhong (BL40) and Ashi acupoints for 5 consecutive days. Plasma cortisol levels were assessed before and after the 5-day treatment session. The visual analog scale (VAS) scores were recorded at baseline and throughout the 5-day treatment session.

Results

After the treatment session, the plasma cortisol levels and VAS scores decreased significantly in both groups. In the laser acupuncture group, the VAS scores decreased significantly on days 4 and 5, and an enhanced reduction in VAS scores was observed.

Conclusion

Laser acupuncture plus Chinese cupping at the Weizhong (BL40) and Ashi acupoints effectively reduced pain and inflammation in chronic nonspecific LBP. This therapy could be a suitable option for LBP treatment in clinical settings.

Efficacy of Auricular Acupressure for Chronic Low Back Pain: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Objectives

To identify the efficacy of auricular acupressure on pain and disability for chronic LBP by systematic review.

Methods

A search of randomized controlled trials was conducted in four English medical electronic databases and three Chinese databases. Two reviewers independently retrieved related studies, assessed the methodological quality, and extracted data with a standardized data form. Meta-analyses were performed using all time-points meta-analysis.

Results

A total of 7 trials met the inclusion criteria, of which 4 had the low risk of bias. The findings of this study showed that, for the immediate effect, auricular acupressure had large, significant effects in improving pain within 12 weeks. As for the follow-up effect, the pooled estimates also showed promising effect at 4-week follow-up after 4-week intervention (standardized mean difference = −1.13, 95% CI (−1.70, −0.56), P < 0.001). But, for the disability level, the therapeutic effect was not significant (mean difference = −1.99, 95% CI (−4.93, 0.95), P = 0.18). No serious adverse effects were recorded.

Conclusions

The encouraging evidence of this study indicates that it is recommended to provide auricular acupressure to patients with chronic low back pain. However, a more accurate estimate of the effect will require further rigorously designed large-scale RCTs on chronic LBP for improving pain and disability.

Effectiveness and safety of moxibustion treatment for non-specific lower back pain: protocol for a systematic review

INTRODUCTION

Many patients experience acute lower back pain that becomes chronic pain. The proportion of patients using complementary and alternative medicine to treat lower back is increasing. Even though several moxibustion clinical trials for lower back pain have been conducted, the effectiveness and safety of moxibustion intervention is controversial. The purpose of this study protocol for a systematic review is to evaluate the effectiveness and safety of moxibustion treatment for non-specific lower back pain patients.

METHODS AND ANALYSIS

We will conduct an electronic search of several databases from their inception to May 2017, including Embase, PubMed, Cochrane Central Register of Controlled Trial, Allied and Complementary Medicine Database, Wanfang Database, Chongqing VIP Chinese Science and Technology Periodical Database, China National Knowledge Infrastructure Database, Korean Medical Database, Korean Studies Information Service System, National Discovery for Science Leaders, Oriental Medicine Advanced Searching Integrated System, the Korea Institute of Science and Technology, and KoreaMed. Randomised controlled trials investigating any type of moxibustion treatment will be included. The primary outcome will be pain intensity and functional status/disability due to lower back pain. The secondary outcome will be a global measurement of recovery or improvement, work-related outcomes, radiographic improvement of structure, quality of life, and adverse events (presence or absence). Risk ratio or mean differences with a 95% confidence interval will be used to show the effect of moxibustion therapy when it is possible to conduct a meta-analysis.

ETHICS AND DISSEMINATION

This review will be published in a peer-reviewed journal and will be presented at an international academic conference for dissemination. Our results will provide current evidence of the effectiveness and safety of moxibustion treatment in non-specific lower back pain patients, and thus will be beneficial to patients, practitioners, and policymakers.

Immune Modulation and Treatment of Human Papilloma Virus-Related Warts with Energetics of Living Systems Acupuncture

Background: Cutaneous warts are small skin lesions formed as a result of infection by the human papilloma virus (HPV). In the lesion, viral manipulation creates a microenvironment that favors virus survival and reproduction. Most lesions eventually regress, probably as a result of a Th1-mediated immune response. However, some warts fail to regress and become persistent. Objective: The efficacy of treatment of persistent HPV-caused warts with Energetics of Living Systems acupuncture and monitored immune system involvement was tested. Methods: Eighteen patients with persistent warts were recruited for the study; 9 received acupuncture treatment and 9 received placebo. Each patient was treated 4 times. Results: Clinical success was defined as total clearance of all lesions with no recurrence for 3 months. In the treatment group, clinical success was 36.6% versus 0% in the placebo group. In the treatment group, the level of interleukin (IL)-10 decreased. In a comparison of patients with cleared warts and overall patients with nonresponding warts, different expression levels of IL-8, IL-10, tumor necrosis factor-α, IL-6, and interferon-γ were found, although these differences were not always statistically significant. Trends of differences (not significant) were observed in leukocyte levels. Acupuncture eliminated persistent warts in some of the patients, along with inducing changes in immunologic parameters. Conclusions: Taking the clinical and immunologic outcomes together, clearance of persistent warts following acupuncture might be due to a shift toward a Th1 immune response, or an anti-inflammatory effect against the lesion-induced microenvironment.

Dry cupping for plantar fasciitis: a randomized controlled trial

[Purpose] The purpose of this study was to determine the effects of dry cupping on pain and function of patients with plantar fasciitis. [Subjects and Methods] Twenty-nine subjects (age 15 to 59 years old, 20 females and 9 males), randomly assigned into the two groups (dry cupping therapy and electrical stimulation therapy groups), participated in this study. The research design was a randomized controlled trial (RCT). Treatments were provided to the subjects twice a week for 4 weeks. Outcome measurements included the Visual Analogue Pain Scale (VAS) (at rest, first in the morning, and with activities), the Foot and Ankle Ability Measure (FAAM), the Lower Extremity Functional Scale (LEFS), as well as the pressure pain threshold. [Results]The data indicated that both dry cupping therapy and electrical stimulation therapy could reduce pain and increase function significantly in the population tested, as all the 95% Confidence Intervals (CIs) did not include 0 except for the pressure pain threshold. There was no significant difference between the dry cupping therapy and electrical stimulation groups in all the outcome measurements. [Conclusion] These results support that both dry cupping therapy and electrical stimulation therapy could reduce pain and increase function in the population tested.

Cost-effectiveness of acupuncture in an employee population: A retrospective analysis

OBJECTIVES

To determine whether acupuncture is a cost-effective adjunct to usual care for Mayo Clinic employees and their dependents experiencing pain symptoms.

DESIGN

Retrospective review of the medical and billing records of 466 employee-patients and their dependents who had received acupuncture as part of their care and 466 propensity score-matched control patients.

INTERVENTIONS

Usual care in combination with acupuncture compared with usual care alone.

MAIN OUTCOME MEASURES

The primary outcome measure was the total costs of care for all medical care and pharmacy services incurred from 1year before the index visit to 14 months after the index date. Secondary outcomes included the number of hospital visits, total inpatient days, emergency department visits, primary care or general medicine office visits, specialty office visits, and physical therapy services. Pain scores (patient-rated scores from 0 to 10) were extracted from the medical record, if available.

RESULTS

Costs of care were similar between the 2 groups. No cost savings were noted for the acupuncture group.

CONCLUSIONS

Several limitations to the study may have precluded a finding of cost-effectiveness. Future studies should include prospective evaluation of costs and other outcomes in a comparison between acupuncture and usual care in a randomized control trial.

Study of acupuncture for low back pain in recent 20 years: a bibliometric analysis via CiteSpace

Background

Acupuncture has been applied to relieve low back pain (LBP) in many countries. However, a bibliometric analysis of the global use of acupuncture for LBP is rare.

Objective

The aim of this study was to demonstrate the state of the art and trends concerning the global use of acupuncture for LBP in recent 20 years.

Methods

Literature relating to acupuncture for LBP from 1997 to 2016 was retrieved from Web of Science. CiteSpace was used to analyze country/institution, cited journals, authors/cited authors, cited references, and keywords. An analysis of counts and centrality was used to reveal publication outputs, countries/institutions, core journals, active authors, foundation references, hot topics, and frontiers.

Results

A total of 958 references were obtained, and the total number of publications continually increased over the investigated period. Journal articles (662) were the most frequently occurring document type. The most productive country and institution in this field was the USA (342) and Harvard University (47), respectively. The J Altern Complem Med (69) was the most productive journal, and Pain (636) was the most cocited journal, which reflected the nature of the research. The Haake’s (2007) article (cocitation counts: 130) and the Cherkin’s (2001) article (centrality: 0.59) were the most representative and symbolic references, with the highest cocitation number and centrality, respectively. Cherkin was the most influential author, with the highest number of publications of 25 and a cocitation number of 226. The four hot topics in acupuncture for LBP were research method, evaluation, economy, and comprehensive therapy. The three frontier topics were intervention, test reliability, and prevalence.

Conclusion

This study provides an insight into acupuncture for LBP and valuable information for acupuncture researchers to identify new perspectives on potential collaborators and cooperative institutions, hot topics, and research frontiers.

Providing chronic pain management in the "Fifth Vital Sign" Era: Historical and treatment perspectives on a modern-day medical dilemma

BACKGROUND

Over 100 million Americans are living with chronic pain, and pain is the most common reason that patients seek medical attention. Despite the prevalence of pain, the practice of pain management and the scientific discipline of pain research are relatively new fields compared to the rest of medicine - contributing to a twenty-first century dilemma for health care providers asked to relieve suffering in the "Fifth Vital Sign" era.

METHODS

This manuscript provides a narrative review of the basic mechanisms of chronic pain and history of chronic pain management in the United States - including the various regulatory, health system and provider factors that contributed to the decline of multidisciplinary pain treatment in favor of the predominant opioid treatment strategy seen today. Multiple non-opioid pain treatment strategies are then outlined. The manuscript concludes with three key questions to help guide future research at the intersection of pain and addiction.

CONCLUSIONS

The assessment and treatment of chronic pain will continue to be one of the most common functions of a health care provider. To move beyond an over reliance on opioid medications, the addiction and pain research communities must unite with chronic pain patients to increase the evidence base supporting non-opioid analgesic strategies.

The risk associated with spinal manipulation: an overview of reviews

BACKGROUND

Spinal manipulative therapy (SMT) is a widely used manual treatment, but many reviews exist with conflicting conclusions about the safety of SMT. We performed an overview of reviews to elucidate and quantify the risk of serious adverse events (SAEs) associated with SMT.

METHODS

We searched five electronic databases from inception to December 8, 2015. We included reviews on any type of studies, patients, and SMT technique. Our primary outcome was SAEs. Quality of the included reviews was assessed using a measurement tool to assess systematic reviews (AMSTAR). Since there were insufficient data for calculating incidence rates of SAEs, we used an alternative approach; the conclusions regarding safety of SMT were extracted for each review, and the communicated opinion were judged by two reviewers independently as safe, harmful, or neutral/unclear. Risk ratios (RRs) of a review communicating that SMT is safe and meeting the requirements for each AMSTAR item, were calculated.

RESULTS

We identified 283 eligible reviews, but only 118 provided data for synthesis. The most frequently described adverse events (AEs) were stroke, headache, and vertebral artery dissection. Fifty-four reviews (46%) expressed that SMT is safe, 15 (13%) expressed that SMT is harmful, and 49 reviews (42%) were neutral or unclear. Thirteen reviews reported incidence estimates for SAEs, roughly ranging from 1 in 20,000 to 1 in 250,000,000 manipulations. Low methodological quality was present, with a median of 4 of 11 AMSTAR items met (interquartile range, 3 to 6). Reviews meeting the requirements for each of the AMSTAR items (i.e. good internal validity) had a higher chance of expressing that SMT is safe.

CONCLUSIONS

It is currently not possible to provide an overall conclusion about the safety of SMT; however, the types of SAEs reported can indeed be significant, sustaining that some risk is present. High quality research and consistent reporting of AEs and SAEs are needed.

Treatment of persistent pain from torture: review and commentary

Torture and the conditions under which it is inflicted often leave persistent painful disorders. Because there may be no lasting signs, persistent pain is often misconceived as a somatic representation of psychological distress, also common after torture. This serious failure to understand the nature of persistent pain means that pain is largely overlooked and untreated in torture survivors. We carried out a systematic review on treatments for pain from torture, but found few studies and little use of current understanding and evidence. We discuss this in the context of treating pain associated with psychological distress and of the broader problems faced by the refugee and torture survivor that may take priority over pain. We propose clinical and research implications for this neglected field.

BIBLIOMETRIC ANALYSIS OF ACUPUNCTURE RESEARCH FRONTS AND THEIR WORLDWIDE DISTRIBUTION OVER THREE DECADES

Background:

Considerable research has been conducted on acupuncture worldwide. This study chronologically examined the changing features and research fronts of acupuncture and elucidated the differences among the six most productive countries.

Methods:

Bibliographic coupling is a powerful tool for identifying the research fronts of a field. Acupuncture-related publications worldwide and from the six most productive countries during 1983-2012 were retrieved from the Science Citation Index Expanded and Social Science Citation Index. To form the research fronts, the 100 most highly cited papers (HCPs) were clustered in terms of references shared.

Results:

The United States had the highest proportion of HCPs. The effectiveness of acupuncture in areas such as relieving neck and back pain, migraines and headaches, and knee osteoarthritis symptoms was a predominant topic. Initially, the endogenous opioid peptide system was the primary research focus in the acupuncture mechanism research; however, during 1993-2012, researchers focused more on the functional magnetic resonance imaging of brain activity. In addition, acupuncture use and prevalence, the attitudes of health practitioners, and the effects of expectancy and belief were also major topics. Researches from Western countries, including the United States, England, and Germany, showed more interest in clinical trials and economic- and ethics-related studies, whereas those from East Asian countries including China, Japan, and South Korea focused more on mechanism research.

Conclusion:

Western countries dominated the research fronts of acupuncture. The patterns of the research fronts varied worldwide, indicating continuity and innovation in research in each country.

Medication Overuse in Chronic Pain

PURPOSE OF REVIEW

Chronic pain is usually managed by various pharmacotherapies after exhausting the conservative modalities such as over-the-counter choices. The goal of this review is to investigate current state of opioids and non-opioid medication overuse that includes NSAIDs, skeletal muscle relaxants, antidepressants, membrane stabilization agents, and benzodiazepine. How to minimize medication overuse and achieve better outcome in chronic pain management?

RECENT FINDINGS

Although antidepressants and membrane stabilization agents contribute to the crucial components for neuromodulation, opioids were frequently designated as a rescue remedy in chronic pain since adjunct analgesics usually do not provide instantaneous relief. The updated CDC guideline for prescribing opioids has gained widespread attention via media exposure. Both patients and prescribers are alerted to respond to the opioid epidemic and numerous complications. However, there has been overuse of non-opioid adjunct analgesics that caused significant adverse effects in addition to concurrent opioid consumption. It is a common practice to extrapolate the WHO three-step analgesic ladder for cancer pain to apply in non-cancer pain that emphasizes solely on pharmacologic therapy which may result in overuse and escalation of opioids in non-cancer pain. There has been promising progress in non-pharmacologic therapies such as biofeedback, complementary, and alternative medicine to facilitate pain control instead of dependency on pharmacologic therapies. This review article presents the current state of medication overuse in chronic pain and proposes precaution to balance the risk and benefit ratio. It may serve as a premier for future study on clinical pathway for comprehensive chronic pain management and reduce medication overuse.

Significant and sustaining elevation of blood oxygen induced by Chinese cupping therapy as assessed by near-infrared spectroscopy

Cupping therapy has been used in traditional Chinese medicine for thousands of years to relieve muscle pain/tendency/fatigue and to cure or reduce symbols of other diseases. However, its therapeutic effect is sparsely interpreted in the language of modern physiology. To objectively evaluate its therapeutic effect, we focused on dry cupping treatment and utilized near-infrared spectroscopy (NIRS) to assess the concentration change in oxy-hemoglobin ([HbO₂]), deoxy-hemoglobin ([Hb]), and blood volume in the course of cupping therapy over 13 volunteers on the infraspinatus muscle, where is usually applied for shoulder pains. Both a prominent drop in [Hb] and a significant elevation in [HbO₂] in the tissue surrounding the cupping site were observed during both cupping and post-treatment, manifesting the enhancement of oxygen uptake. This resulting promotion indicates potential positive therapeutic effect of cupping therapy in hemodynamics for facilitating muscular functions.

Bienfaits du tai-chi sur la santé

Objectif

Résumer les données probantes sur les bienfaits du tai-chi sur la santé.

Sources d’information

Une revue de la littérature sur les bienfaits du tai-chi sur 25 affections différentes, de même que sur la santé en général et sur la forme physique, a été effectuée afin d’actualiser une revue des revues systématiques effectuée en 2014. Les revues systématiques et les essais cliniques récents ont été évalués et organisés en 5 groupes : données excellentes, bonnes, acceptables ou préliminaires, étayant un bienfait ou n’étayant aucun bienfait direct.

Message principal

Au cours des 45 dernières années, plus de 500 essais et 120 revues systématiques ont été publiés sur les bienfaits du tai-chi sur la santé. Les revues systématiques sur le tai-chi pour différentes affections ont donné lieu à d’excellentes données étayant un bienfait pour la prévention des chutes, l’arthrose, la maladie de Parkinson, la réadaptation dans les cas de maladie pulmonaire obstructive chronique et l’amélioration de la capacité cognitive chez les personnes âgées. Il existe de bonnes données étayant un bienfait pour la dépression, la réadaptation cardiaque et après un AVC et la démence. Les données étayant un bienfait pour l’amélioration de la qualité de vie des patients atteints de cancer, de fibromyalgie, d’hypertension et d’ostéoporose sont acceptables. Les données actuelles étayent l’absence d’un bienfait direct pour le diabète, la polyarthrite rhumatoïde ou l’insuffisance cardiaque chronique. Les revues systématiques portant sur les bienfaits sur la santé en général et la forme physique font état d’excellentes données étayant un bienfait pour l’amélioration de l’équilibre et de la capacité aérobique chez les personnes en mauvaise forme physique. Les données étayant une plus grande force dans les membres inférieurs sont bonnes. Les données étayant une amélioration du bien-être et du sommeil sont acceptables. Aucune étude n’a révélé que le tai-chi aggravait une affection. Une récente revue systématique sur l’innocuité du tai-chi a révélé que les événements indésirables étaient habituellement mineurs et principalement de nature musculosquelettique; aucun événement indésirable grave lié au tai-chi n’a été rapporté.

Conclusion

Il existe d’abondantes données étayant les effets du tai-chi sur la santé et la forme physique. En s’appuyant sur ces données, les médecins peuvent maintenant faire des recommandations éclairées à leurs patients, en précisant que le tai-chi fait toujours l’objet de recherches. Aussi, toute affection clinique doit faire l’objet d’un suivi médical continu.

Health benefits of tai chi: What is the evidence?

OBJECTIVE

To summarize the evidence on the health benefits of tai chi.

SOURCES OF INFORMATION

A literature review was conducted on the benefits of tai chi for 25 specific conditions, as well as for general health and fitness, to update a 2014 review of systematic reviews. Systematic reviews and recent clinical trials were assessed and organized into 5 different groups: evidence of benefit as excellent, good, fair, or preliminary, or evidence of no direct benefit.

MAIN MESSAGE

During the past 45 years more than 500 trials and 120 systematic reviews have been published on the health benefits of tai chi. Systematic reviews of tai chi for specific conditions indicate excellent evidence of benefit for preventing falls, osteoarthritis, Parkinson disease, rehabilitation for chronic obstructive pulmonary disease, and improving cognitive capacity in older adults. There is good evidence of benefit for depression, cardiac and stroke rehabilitation, and dementia. There is fair evidence of benefit for improving quality of life for cancer patients, fibromyalgia, hypertension, and osteoporosis. Current evidence indicates no direct benefit for diabetes, rheumatoid arthritis, or chronic heart failure. Systematic reviews of general health and fitness benefits show excellent evidence of benefit for improving balance and aerobic capacity in those with poor fitness. There is good evidence for increased strength in the lower limbs. There is fair evidence for increased well-being and improved sleep. There were no studies that found tai chi worsened a condition. A recent systematic review on the safety of tai chi found adverse events were typically minor and primarily musculoskeletal; no intervention-related serious adverse events have been reported.

CONCLUSION

There is abundant evidence on the health and fitness effects of tai chi. Based on this, physicians can now offer evidence-based recommendations to their patients, noting that tai chi is still an area of active research, and patients should continue to receive medical follow-up for any clinical conditions.

Acupuncture for musculoskeletal pain: A meta-analysis and meta-regression of sham-controlled randomized clinical trials

The aims of this systematic review were to study the analgesic effect of real acupuncture and to explore whether sham acupuncture (SA) type is related to the estimated effect of real acupuncture for musculoskeletal pain. Five databases were searched. The outcome was pain or disability immediately (≤1 week) following an intervention. Standardized mean differences (SMDs) with 95% confidence intervals were calculated. Meta-regression was used to explore possible sources of heterogeneity. Sixty-three studies (6382 individuals) were included. Eight condition types were included. The pooled effect size was moderate for pain relief (59 trials, 4980 individuals, SMD -0.61, 95% CI -0.76 to -0.47; P < 0.001) and large for disability improvement (31 trials, 4876 individuals, -0.77, -1.05 to -0.49; P < 0.001). In a univariate meta-regression model, sham needle location and/or depth could explain most or all heterogeneities for some conditions (e.g., shoulder pain, low back pain, osteoarthritis, myofascial pain, and fibromyalgia); however, the interactions between subgroups via these covariates were not significant (P < 0.05). Our review provided low-quality evidence that real acupuncture has a moderate effect (approximate 12-point reduction on the 100-mm visual analogue scale) on musculoskeletal pain. SA type did not appear to be related to the estimated effect of real acupuncture.

Moxibustion Treatment for Knee Osteoarthritis: A Systematic Review and Meta-Analysis

To determine whether the administration of moxibustion is an effective treatment for knee osteoarthritis (KOA).We conducted a search of relevant articles using Medline, EMBASE, the Web of Science, and the Cochrane Library published before October 2015. The Western Ontario and McMaster Universities' Osteoarthritis Index (WOMAC scale) and the short form 36 questionnaire (SF-36 scale) were assessed. Evidence grading was evaluated according to the Grading of Recommendations, Assessment, Development and Evaluation system.Four studies containing 746 participants fulfilled the inclusion criteria in the final analysis. In terms of quality of life (QOL), the meta-analysis of 2 randomized clinical trials (RCTs) showed significantly effects of moxibustion only in bodily pain (BP) compared with those in the control group (n = 348; weighted mean difference [WMD], 4.36; 95% confidence intervals [CIs], 2.27-6.44; P < 0.0001; heterogeneity: χ = 1.53, P = 0.22, I = 34%) in all of the subcategories of the SF-36 scale, with moderate quality. The meta-analysis of the 2 included trials showed that there was not a statistically significant difference in the pain or function subscale for the WOMAC scale when the 2 groups were compared (n = 322; WMD, 17.63; 95% CI, -23.15-58.41; P = 0.40; heterogeneity: χ = 19.42, P < 0.0001, I = 95%), with low or moderate quality separately.The administration of moxibustion can to some extent alleviate the symptoms of KOA. More rigorous, randomized controlled trials are required in the future.

Plant Natural Product Puerarin Ameliorates Depressive Behaviors and Chronic Pain in Mice with Spared Nerve Injury (SNI)

Simultaneous relief of the pain from body and brain remains an ongoing challenge. The aim of the present study was to clarify whether plant-derived isoflavone puerarin could ameliorate comorbid depression and pain. We investigated the effects of puerarin on depressive-like behaviors and neuropathic pain in C57BL/6 N mice with spared nerve injury (SNI). After SNI surgery, mice were allowed to recover spontaneously for 7 days and subsequently treated with puerarin, anti-depressant citalopram, and analgesic ibuprofen, alone or in combination, for 8 or 14 days. Forced swim test and tail suspension test were used to assess depressive-like behaviors, whereas von Frey filament test was used to estimate the sensitivity to the mechanical stimulation. Our results suggested that puerarin effectively ameliorated depression and pain in SNI mice although citalopram exhibited anti-depressant activity. In contrast, ibuprofen showed lesser activities against SNI-induced depression and pain. Further mechanistic studies revealed the uniqueness of puerarin as follows: (1) puerarin did not recover SNI-induced depletion of reduced glutathione and loss of superoxide dismutase (SOD), whereas citalopram and ibuprofen showed somewhat antioxidant activities; (2) puerarin markedly promoted the activation of CREB pathway although puerarin and citalopram activated ERK pathway to the same extent; (3) puerarin rapidly and persistently induced brain-derived neurotrophic factor (BDNF) expression whereas citalopram only induced BDNF expression after a prolonged stimulation. Collectively, these results suggest that puerarin may ameliorate the SNI-induced depression and pain via activating ERK, CREB, and BDNF pathways. Puerarin may serve as new lead compound for the development of novel therapeutics for depression and pain comorbidity.

The Effectiveness of Cupping Therapy on Relieving Chronic Neck and Shoulder Pain: A Randomized Controlled Trial

The research aimed to investigate the effectiveness of cupping therapy (CT) in changes on skin surface temperature (SST) for relieving chronic neck and shoulder pain (NSP) among community residents. A single-blind experimental design constituted of sixty subjects with self-perceived NSP. The subjects were randomly allocated to two groups. The cupping group received CT at SI 15, GB 21, and LI 15 acupuncture points, and the control group received no intervention. Pain was assessed using the SST, visual analog scale (VAS), and blood pressure (BP). The main results were SST of GB 21 acupuncture point raised from 30.6°C to 32.7°C and from 30.7°C to 30.6°C in the control group. Neck pain intensity (NPI) severity scores were reduced from 9.7 to 3.6 in the cupping group and from 9.7 to 9.5 in the control group. The SST and NPI differences between the groups were statistically significant (P < 0.001). One treatment of CT is shown to increase SST. In conjunction with the physiological effect the subjective experience of NSP is reduced in intensity. Further studies are required to improve the understanding and potential long-term effects of CT.

Acupuncture Treatment of Chronic Low Back Pain by Using the Jingjin (Meridian Sinews) Model

This case report details the unexpected and sustained relief from chronic low back pain in a patient after a single acupuncture treatment. The treatment administered on that occasion was based on the jingjin (i.e., "meridian sinew") model of traditional acupuncture. Treatments based on the jingjin model involve needling the ah shi (i.e., locally tender) points in myofascial tissue along the jingjin pathway. Tight chains can be needled to treat symptoms that are either close to or at some distance from the site of the needling treatment. In this patient, the points were in the gastrocnemius muscle and the hamstring muscles, which are part of the Bladder jingjin pathway. The patient, a 69-year-old woman, had had back pain for more than 40 years. The relief from the pain occurred within a day after the treatment and, at the time of this report, the relief has persisted for 5 months. This report examines two possible mechanisms for such a result: (1) a local increase in the extensibility of the hamstrings could be responsible or (2) the complex interactions within the central nervous system that are involved in acupuncture treatment could be more important factors.

Acupuncture to Treat Sleep Disorders in Postmenopausal Women: A Systematic Review

Sleep disorders are commonly observed among postmenopausal women, with negative effects on their quality of life. The search for complementary therapies for sleep disorders during postmenopausal period is of high importance, and acupuncture stands out as an appropriate possibility. The present review intended to systematically evaluate the available literature, compiling studies that have employed acupuncture as treatment to sleep disorders in postmenopausal women. A bibliographic search was performed in PubMed/Medline and Scopus. Articles which had acupuncture as intervention, sleep related measurements as outcomes, and postmenopausal women as target population were included and evaluated according to the Cochrane risk of bias tool and to the STRICTA guidelines. Out of 89 search results, 12 articles composed our final sample. A high heterogeneity was observed among these articles, which prevented us from performing a meta-analysis. Selected articles did not present high risk of bias and had a satisfactory compliance rate with STRICTA guidelines. In general, these studies presented improvements in sleep-related variables. Despite the overall positive effects, acupuncture still cannot be stated as a reliable treatment for sleep-related complaints, not due to inefficacy, but rather limited evidence. Nevertheless, results are promising and new comprehensive and controlled studies in the field are encouraged.

Jingtong Granule: A Chinese Patent Medicine for Cervical Radiculopathy

Objective. This paper systematically assessed the efficacy and safety of Jingtong granule (JG) for cervical radiculopathy (CR). Methods. Randomized controlled trials comparing JG with no intervention, placebo, or conventional therapies were retrieved. The trials testing JG combined with conventional therapies versus conventional therapies were also enrolled. Study selection, methodological assessment, data extraction, and analysis were conducted in accordance with the Cochrane standards. The strength of evidence was evaluated according to GRADE approach. Results. Three trials with 400 participants were included. Methodological quality was evaluated as generally low. One study found that JG showed significant difference on decreasing pain scores compared with placebo. Meta-analysis indicated that JG plus conventional analgesic exhibited a significant immediate effect on the pain scores (WMD = 1.63; 95% CI: 1.29 to 1.98; P < 0.00001). Additionally, JG combined with analgesic presented beneficial immediate effect on neck disability index. However, the treatment effects of JG demonstrated in the trials were not large, and the safety of JG was unproven. Finally the evidence level was evaluated to be low. Conclusions. Our results indicated that JG showed some potential benefits for CR. Nevertheless, treatment effects are uncertain due to both the methodological concerns and the very modest reported improvements.

The effect of an acupressure backrest on pain and disability in office workers with chronic low back pain: A randomized, controlled study and patients' preferences

OBJECTIVE

This study investigated the effects of an acupoint-stimulating lumbar backrest on pain and disability in office workers who suffering from low back pain (LBP) as well as the preference influence on pain and disability.

METHODS

Sixty-four participants were randomly assigned to two groups: one with no intervention (n=32) and another with 1 month of backrest use (n=32). An additional group (n=37) who wished to try 1 month of acupressure backrest were recruited to indicate the preference effect. Pain and disability were two key outcomes.

RESULTS

Significant differences between control and randomized acupressure backrest groups were found at 2 week period for disability and at 4 weeks for pain after the backrest use. Also, significant differences were found in both groups for 3 month period with an increase of the treatment effect on pain and disability. Both control and randomized acupressure backrest groups showed greater improvement in pain and disability scores which were more than the minimal clinically important change (30% improvement for both outcomes). No significant difference was found for pain and disability between the randomized and preferred backrest groups.

CONCLUSION

These findings suggested 1-month of acupressure backrest use could improve LBP conditions. Preference was not a powerful moderator to the significant treatment effect.
