Needling trigger points for treating myofascial pain syndrome: A systematic review and meta-analysis

BACKGROUND

Myofascial pain syndrome (MPS) is a widespread musculoskeletal disorder characterized by myofascial trigger points. Needling trigger points is one of the most common therapeutic interventions to treat MPS. However, it is unclear whether needling trigger points is superior to other non-pharmacological interventions.

METHODS

Randomized clinical trials (RCTs) which compared the effectiveness of needling trigger points and other non-pharmacological therapies for treating MPS, were searched in the databases of PubMed, Web of Science, Embase, Cochrane Library, CNKI, WanFang, VPCS, and Sinomed, from their inception to August 25th, 2024. Two independent reviewers extracted relevant data on study characteristics and assessed the risk of bias using the Cochrane Risk of Bias Tool.

RESULTS

Of the 1968 articles initially screened, 13 RCTs were included. Needling trigger points treatment were more efficacious than non-pharmacological therapies in reducing Visual Analog Scale (VAS) scores (MD = -1.32; 95 % CI = -1.84 to -0.81; P < 0.0001) and the Roland-Morris Disability Questionnaire (RMDQ) scores (MD = -2.77; 95 % CI = -3.58 to -1.97; P < 0.0001).

CONCLUSION

This systematic review has shown that needling trigger points could be a more effective option than other non-pharmacological therapies to improve the symptoms of MPS. Clinical trials of robust quality are required to promote further the evidence-based application of needling trigger points for MPS.

Therapeutic approach to fibromyalgia: a consensus statement on pharmacological and non-pharmacological treatment from the neuropathic pain special interest group of the Italian neurological society

BACKGROUND

Although fibromyalgia is a disabling disease, there is no targeted therapy for specific neurotransmitters or inflammatory mediators. Our aim was to provide neurologists with practical guidance for the management of these difficult patients based on a critical, narrative and non-systematic review of randomized controlled trials (RCTs) from the last 10 years.

METHODS

The members of the Special Interest Group Neuropathic Pain of the Italian Neurological Society evaluated the randomized controlled trials (RCTs) of the last 10 years and answered questions that allow a consensus on the main pharmacological and non-pharmacological approaches.

RESULTS

The neuropathic pain working group agreed on prescribing antiepileptic drugs or antidepressants in the case of comorbidities with anxiety and depression. As a second choice, experts have agreed on the association of antiepileptics and antidepressants, while they disagree with the use of opioids. Medical cannabis and nutraceuticals are promising new treatment options, although more data is needed to prove their efficacy. The neurologists agreed in suggesting physical activity at the first visit, particularly aerobic and strength training. As a second choice, they considered a cognitive behavioral therapy approach to be useful.

CONCLUSIONS

Pharmacologic treatment with antiepileptic drugs and antidepressants in patients with co-occurring anxiety and depression, as well as an early nonpharmacologic approach based primarily on physical activity, may be a useful indication in contemporary neurology clinical practice. Non-pharmacological options, such as cognitive behavioral therapy and non-invasive brain stimulation NIBS, could improve evidence of efficacy and lead to relevant improvement in FM-related disability.

The effectiveness of acupuncture in cancer pain treatment

Introduction

In recent years, pain has been recognized as a primary factor significantly diminishing the quality of life in cancer patients. Recent data have prompted the establishment and increased application of non-pharmacological interventions in pain management, such as acupuncture.

Objectives

This review assesses literature from 2018 to 2023 on the impact of acupuncture on pain management and quality of life in cancer patients, with a particular focus on reducing pain intensity. The effectiveness of acupuncture therapy was compared with the traditional treatment of pain symptoms, with a focus on the patients' quality of life.

Conclusions

Although no conclusive scientific evidence confirms the effectiveness of acupuncture in treating cancer pain symptoms, numerous studies have demonstrated its ability to reduce pain, better control pain, decrease analgesic intake, and significantly improve patients' quality of life. Further research is needed to unequivocally confirm the clinical benefits of acupuncture.

Early-Phase Intervention With Traditional Japanese Acupuncture and Moxibustion for Fibromyalgia: A Case Report

Fibromyalgia (FM) is a common chronic pain with no established treatment. Acupuncture is an expected treatment for FM though a diagnosis of FM tends to be delayed, and the advantage is still unclear in early-phase intervention with acupuncture treatment for FM. A 51-year-old woman with panic disorder presented with a four-month history of whole-body pain and was diagnosed with FM. She was unable to do housework or control her pain with medication. And she took 10 mg of paroxetine, a selective serotonin reuptake inhibitor (SSRI), to treat her depressive mood or panic disorder. A traditional Japanese acupuncture and moxibustion treatment, Hokushin-kai, was started. According to the Oriental medical diagnosis, she was categorized with "hyperactivity of liver yang," "dampness encumbering spleen," and "kidney yin deficiency" patterns. The treatment was administered once a week, and only one or two sterilized disposable needles were inserted into each acupoint (such as BL19, LR8, or KI3) for 10 minutes and with no manipulations. At the first presentation, the numerical rating scale (NRS) value was 6. After six weeks, her whole-body pain level remained around NRS 0-2 for 4-5 days after each treatment session. She was then able to resume housework after 12 weeks. Since ancient times, acupuncturists have recognized how acupuncture becomes less effective over time, especially for chronic pain. Moreover, the concept of a treatment-sensitive period for chronic pain prevention has recently been proposed. Further research, including early-phase interventions for acupuncture treatment, is required to evaluate the clinical effects of various treatments on FM.

Effectiveness of Acupuncture and Brief Telehealth Intervention for Individuals With Posttraumatic Stress Disorder

PURPOSE

This open-trial pilot study evaluated the feasibility and effectiveness of acupuncture with brief therapy (ABT) for individuals with posttraumatic stress disorder (PTSD).

METHOD

Participants included 27 individuals with PTSD diagnoses confirmed using the Clinician-Administered PTSD Scale for DSM-5. Before ABT, 22 participants completed eight acupuncture sessions and three telehealth sessions of a brief treatment program for PTSD (Brief Relaxation, Education, and Trauma Healing [BREATHE]).

RESULTS

ABT significantly reduced PTSD symptoms, depression symptoms, anxiety, and improved trauma-related cognition.

CONCLUSION

Acupuncture can play an important role in mental health recovery, and combining acupuncture with a brief, telehealth-based treatment (BREATHE) may assist recovery among individuals with PTSD. [Journal of Psychosocial Nursing and Mental Health Services, 62(11), 35-45.].

Temporal Summation but Not Expectations of Pain Relief Predict Response to Acupuncture Treatment in Fibromyalgia

Fibromyalgia (FM) is a common chronic pain condition for which acupuncture treatment is increasingly utilized. However, there is no universally accepted measure to predict whether a specific patient will benefit from acupuncture. This is a single-center, single-blind, sham-controlled, randomized, noncrossover, longitudinal trial of 76 subjects with FM, assigned to either electroacupuncture (EA) or a placebo control, mock laser (ML) acupuncture. Outcome measures included clinical pain severity (Brief Pain Inventory [BPI]), degree of nociplastic pain (Fibromyalgia Survey Questionnaire), and pressure pain tolerance (PPtol). Baseline measures of temporal summation of pain and expectations for treatment relief were used as predictors. Individuals in both treatment groups experienced significant reductions in BPI (EA: P < .001, ML: P = .018) and Fibromyalgia Survey Questionnaire (EA: P = .032, ML: P = .002) after treatment; however, neither group showed a significant increase in PPtol. Lower temporal summation at baseline was correlated with greater post-treatment improvement in BPI in the EA group (rho = .389, P = .025) but not in the ML group (rho = -.272, P = .109). Lower-baseline temporal summation was correlated with greater decreases in PPtol following EA (rho = .400, P = .040), whereas the opposite was seen for ML (rho = -.562, P = .001). Treatment expectancy at baseline was not correlated with any outcome after EA or ML treatments. Our results support using a quantitative sensory testing metric, temporal summation of pain, but not expectations, to predict analgesia following acupuncture treatment for pain. PERSPECTIVE: A randomized study of acupuncture in FM found baseline temporal summation, but not expectations of pain relief, to be predictive of treatment response. CLINICAL TRIAL REGISTRATION: Registered under ClinicalTrials.gov identifier NCT02064296.

Dysmenorrhea, a Narrative Review of Therapeutic Options

Dysmenorrhea is the most common pathology women of childbearing age face. It is defined as painful uterine cramping associated with menstruation. Primary dysmenorrhea occurs in the absence of an organic cause, whereas secondary dysmenorrhea is pelvic pain associated with an underlying pelvic pathology. The purpose of this review is to discuss the pathophysiology of dysmenorrhea and provide a discussion of pharmacologic and non-pharmacologic treatment options. Prostaglandins play a large role in the pathophysiology of dysmenorrhea by causing myometrial contraction and vasoconstriction. The first-line treatment for dysmenorrhea is with nonsteroidal anti-inflammatory drugs due to the inhibition of cyclooxygenase enzymes, thereby blocking prostaglandin formation, as well as hormonal contraception. Other pharmacologic treatment options include Paracetamol, as well as Gonadotrophic Release Hormone Analogs, which are typically used in the treatment for endometriosis. Non-pharmacologic treatments with strong evidence include heat therapy and physical exercise. There are less evidence-based data behind other modalities for treating dysmenorrhea, such as dietary supplements, acupuncture, and transcutaneous nerve stimulation, and these methods should be used in conjunction with first-line therapy after a discussion of risks and benefits. Lastly, for women who fail medical management, surgical options include endometrial ablation, presacral neurectomy, and laparoscopic uterosacral nerve ablation. Further research is needed to measure the socioeconomic burden of dysmenorrhea on the healthcare system and to evaluate the efficacy of treatment combinations, as a multi-modal approach likely provides the most benefit for women who suffer from this condition.

Treatment of Depression with Acupuncture Based on Pathophysiological Mechanism

Depression is a prevalent mental disorder and has a profound impact on an individual's psychological and physical well-being. It is characterized by a persistently depressed mood, loss of interest, energy loss, and cognitive dysfunction. In recent years, more and more people have changed to mental diseases, such as depression, anxiety, mania and so on. In the incidence of depression, covering all ages, but still mainly young and middle-aged women. Traditional treatments for depression mainly rely on medication and psychotherapy, but these methods are not effective for all patients and are often accompanied by certain side effects. Therefore, finding safe and effective alternative or adjuvant treatments has become a priority. Here we highlight the research progress of acupuncture in the treatment of depression and to explore the mechanism of acupuncture in the treatment of depression. Acupuncture treatment of depression is an ancient and effective method, the mechanism involves multiple biological pathways, for example, by regulating neurotransmitter levels, regulating the neuroendocrine axis, improving neuroplasticity, anti-inflammatory and other effects, improving emotional state and play an antidepressant role. To provide evidence to support the widespread use of acupuncture in clinical practice. We hope to provide new treatment ideas and methods for patients with depression, and even reduce the incidence of depression.

Effectiveness of Complementary and Alternative Medicine in Fibromyalgia Syndrome: A Network Meta-Analysis

Objective

Fibromyalgia (FM) is a prevalent chronic disorder characterized by widespread skeletal muscle pain. In recent years, complementary and alternative medicine (CAM) has increasingly been recognized for its potential in treating FM symptoms. This study aims to assess the efficacy of CAM therapies in mitigating the symptoms of FM.

Methods

This systematic review was registered with INPLASY. A thorough search of both English and Chinese databases was undertaken from their inception until April 15, 2023. The search criteria focused on prospective controlled trials examining CAM therapies in FM patients. The statistical analysis employed mean values and standard deviations. Additionally, an evaluation of the literature's quality and potential biases was conducted.

Results

The search yielded 41 articles, encompassing 2877 FM patients and involving 20 different interventions. All studies were randomized controlled trials (RCTs). The results of the network meta-analysis (NMA) indicated that a combination of Acupuncture and Massage therapy, as well as Navel Needling therapy, effectively alleviated pain symptoms in FM patients. Furthermore, Abdominal Acupuncture and Electroacupuncture were found to be beneficial in improving patients' mood and sleep quality.

Conclusion

Acupuncture + Massage and Umbilical Acupuncture emerged as the most efficacious therapies in relieving pain symptoms in FM patients. Abdominal Acupuncture and Electroacupuncture demonstrated their effectiveness in enhancing mood and sleep quality. Overall, CAM therapies exhibited a high safety profile for patients with fibromyalgia.

Research Trends of Acupuncture Therapy for Chronic Pain-Related Depression or Anxiety from 2003 to 2023: A Bibliometric Analysis

Background

Chronic pain (CP) as a long-lasting stressor can often cause mood disorders, such as depression or anxiety. The comorbidity of CP and mood disorders poses challenges for treatment and increases healthcare costs. Acupuncture has emerged as a widely utilized approach to alleviate both CP and mood disorders. However, there is a lack of well-established bibliometric analyses in this area of research. Therefore, this study aimed to identify the current hotspots and research trends regarding the use of acupuncture for treating CP-related depression or anxiety.

Methods

We searched the Web of Science Core Collection spanning from 2003 to 2023 to identify relevant literature about the use of acupuncture for treating CP-related depression or anxiety. Bibliometric and visualization analyses were performed using CiteSpace 5.7.R5 and Vosviewer 1.6.19 software.

Results

A total of 254 articles published between 2003 and 2023 were included, revealing an upward trajectory with some fluctuations in publication numbers over the past two decades. China and the Beijing University of Chinese Medicine were the most productive country and institution in this field. Fang JQ and Vickers AJ ascended as the most prolific and influential authors, respectively. Trials was the journal with the highest number of publications, while Pain and BMJ-British Medical Journal exhibited the highest citation and centrality, respectively. "Acupuncture", "depression", and "chronic pain" were the top three keywords. The hotspots in this domain encompass types of chronic pain that predispose to negative mood, including fibromyalgia, irritable bowel syndrome (IBS), and neuropathic pain. Randomized controlled trials (RCTs), mechanisms, and evidence-based evaluations are the main research directions.

Conclusion

This study uses bibliometric techniques to analyze the research hotspots and forefronts of acupuncture as a therapeutic approach for CP-related depression or anxiety. Our objective is to provide researchers with valuable references and identify research focal points for future investigations.

Acupuncture for Parkinson's disease-related constipation: current evidence and perspectives

Parkinson's disease-related constipation (PDC) is commonly associated with impaired dopamine transmission and gastrointestinal dysfunction. Current pharmacological treatments have limited efficacy and potential side effects. Acupuncture has shown promise as an alternative or adjunct therapy by modulating the brain-gut axis, gastrointestinal hormones, and autonomic function. Preliminary randomized trials have shown that acupuncture significantly improves constipation symptoms, bowel movements, and comfort compared to sham or drug treatments and is well-tolerated. The mechanisms of action may involve regulating the gut microbiota and mucosal immunity to improve dysbiosis and gastrointestinal motility. However, more rigorous studies are required to optimize acupuncture protocols and determine long-term efficacy and safety. In summary, acupuncture shows promise as an adjunct therapy for PDC, but further research is needed to confirm its efficacy and safety.

Pain Biomarkers in Fibromyalgia Syndrome: Current Understanding and Future Directions

Fibromyalgia is a complex and heterogeneous clinical syndrome, mainly characterized by the presence of widespread pain, possibly associated with a variety of other symptoms. Fibromyalgia can have an extremely negative impact on the psychological, physical and social lives of people affected, sometimes causing patients to experience dramatically impaired quality of life. Nowadays, the diagnosis of fibromyalgia is still clinical, thus favoring diagnostic uncertainties and making its clear identification challenging to establish, especially in primary care centers. These difficulties lead patients to undergo innumerable clinical visits, investigations and specialist consultations, thus increasing their stress, frustration and even dissatisfaction. Unfortunately, research over the last 25 years regarding a specific biomarker for the diagnosis of fibromyalgia has been fruitless. The discovery of a reliable biomarker for fibromyalgia syndrome would be a critical step towards the early identification of this condition, not only reducing patient healthcare utilization and diagnostic test execution but also providing early intervention with guideline-based treatments. This narrative article reviews different metabolite alterations proposed as possible biomarkers for fibromyalgia, focusing on their associations with clinical evidence of pain, and highlights some new, promising areas of research in this context. Nevertheless, none of the analyzed metabolites emerge as sufficiently reliable to be validated as a diagnostic biomarker. Given the complexity of this syndrome, in the future, a panel of biomarkers, including subtype-specific biomarkers, could be considered as an interesting alternative research area.

Research Trends of Acupuncture Therapy on Fibromyalgia from 2000 to 2021: A Bibliometric Analysis

Purpose

Fibromyalgia Syndrome causes great physical and mental discomfort and incurs high costs. Acupuncture has been regarded as the mainstay of treatment for Fibromyalgia Syndrome while the bibliometric analysis of this field has not been summarized properly. Thus, the purpose of this study is to analyze the hotspot of acupuncture for Fibromyalgia Syndrome.

Methods

The core collection database of Web of Science were searched for relevant publications from 2000 to 2021, and countries, institutions, authors, keywords, and literature were analyzed and visualized by bibliometric software CiteSpace V software and Vosviewer software, to explore the scientific achievements, research collaboration networks, research hot spots, and research trends.

Results

868 publications were included in this study. The publications have increased steadily over time, and the type published the most is Article. Pain is the most cited journal. The most prolific country is the USA while the most prolific institution is Univ Michigan. The most prolific and influential authors were Yiwen Lin and Wolfe F respectively. The analysis of keywords and literature showed that long-term efficacy, animal studies, alternative medicine, and electroacupuncture will be the scientific hotspots in acupuncture for fibromyalgia.

Conclusion

This study shows that the number of research studies, researchers, and research institutions on acupuncture for fibromyalgia is increasing from year to year. Future research hotspots will focus on the long-term efficacy of acupuncture in the treatment of fibromyalgia, experimental animal studies, and the development of other alternative medical therapies. In addition, electroacupuncture is receiving more and more attention as a new application of traditional acupuncture therapy.

Knowledge Mapping of Acupuncture for Fibromyalgia from 1990 to 2022: A Bibliometric Analysis

Background

Fibromyalgia is a rheumatic disease with no specific laboratory markers and is insensitive to hormonal drugs and nonsteroidal anti-inflammatory drugs commonly used to treat rheumatism. Guidelines recommend that non-pharmacological therapy should be the first-line treatment for fibromyalgia. Since the publication of the first diagnostic criteria for fibromyalgia in 1990, studies on acupuncture for fibromyalgia have been reported periodically. This study aims to explore the intellectual landscape of acupuncture for fibromyalgia since 1990, and to identify research trends and fronts in this field.

Methods

The Web of Science Core Collection Database was searched for publications on acupuncture for fibromyalgia from 1990 to 2022. VOSviewer and CiteSpace were used to analyze the annual publication, countries, institutions, authors and cited authors, journals and cited journals, references and keywords.

Results

A total of 280 publications were retrieved, and the number of publications showed an overall upward trend. The United States was the most productive country. China Medical University was the institution with the most publications. Lin Yi-wen was the most prolific author, while Wolfe was the most cited author. Evidence-Based Complementary and Alternative Medicine was the journal in which most of the research was published, while Pain was the most cited journal. An article by Wolfe (1990) had the most citations, but an article by Crofford (2001) had the highest centrality. The four most frequently used keywords in the included articles were mechanism, spinal cord, activation and sensitivity.

Conclusion

Acupuncture can effectively relieve pain in patients with fibromyalgia and improve accompanying symptoms such as anxiety and depression. However, the design of clinical trials still needs to be optimized to better verify the efficacy of acupuncture on various clinical symptoms of fibromyalgia. Exploring the central analgesic mechanism of acupuncture on fibromyalgia is also the focus research direction now and future.

Effect of Sham Acupuncture on Chronic Pain: A Bayesian Network Meta-analysis

BACKGROUND

Along with increasing research on acupuncture for chronic pain, the validity of sham acupuncture (SA) has also been argued.

METHODS

Nine databases were searched for randomized controlled trials (RCTs) from the inception date to July 5, 2022. Using Markov Chain Monte Carlo methods, a Bayesian multiple treatment network meta-analysis (NMA) with random-effects model was conducted.

RESULTS

A total of 62 RCTs with 6806 patients and four kinds of treatments (real acupuncture (RA), non-acupuncture (NA), penetrative SA (PSA) and non-penetrative SA (NPSA)) were included. The results indicated that both NPSA and PSA were not superior to NA in improving chronic pain (NPSA: MD -4.77 [95% CI, -11.09 to 1.52]; PSA: MD, -4.96 [95% CI, -10.38 to 0.48]). After combining NPSA and PSA into the SA group, the weak trend of pain relief from SA was still not statistically significant (MD, -4.91 [95% CI, -9.93 to 0.05]). NPSA and PSA had similar effects (MD, 0.18 [95% CI, -5.45 to 5.81]). RA was significantly associated with pain relief, compared with NPSA and PSA (NPSA: MD, -12.03 [95% CI, -16.62 to -7.41]; PSA: MD, -11.85 [95% CI, -15.48 to -8.23]). The results were generally consistent regardless of pain phenotype, frequency, duration, acupuncture methods, analgesic intake, or detection bias.

CONCLUSION

These results suggested that acupuncture was significantly associated with reduced chronic pain. The two kinds of placebo acupuncture, NPSA and PSA, have similar effects. Both NPSA and PSA, with a weak but not significant effect, are appropriate to be inert placebo controls in RCTs for chronic pain.

Efficacy of Dry Needling and Acupuncture in Patients with Fibromyalgia: A Systematic Review and Meta-Analysis

Fibromyalgia (FM) is a syndrome that involves chronic pain, fatigue, sleep disturbance and impaired quality of life and daily functioning. In addition to medical and psychological therapies, other therapies including acupuncture and dry needling aim to reduce pain and disability in patients with FM. The aim of this study was to investigate the efficacy of dry needling and acupuncture in patients with FM regarding pain, function and disability in both the short and the long term. MEDLINE, PubMed, SCOPUS and Web of Science databases were systematically searched for randomized controlled trial studies evaluating efficacy data of dry needling or/and acupuncture treatments to improve pain, fatigue, sleep disturbance and impaired quality of life and/or daily function. A qualitative analysis including the methodological quality and a systematic data synthesis was performed. A total of 25 studies addressed the selection criteria. Most studies had an acceptable methodological quality. Four studies assessed the effect of dry needling, and twenty-one studies assessed the effect of acupuncture. In general, both interventions improved pain, anxiety, depression, fatigue, stiffness, quality of sleep and quality of life. However, both techniques were not compared in any study. Acupuncture and dry needling therapies seems to be effective in patients with FM, since both reduced pain pressure thresholds, anxiety, depression, fatigue, sleep disturbances and disability in the short term. It is still required to compare both techniques and their application in the long term.

Efficacy of nonpharmacological interventions for individual features of fibromyalgia: a systematic review and meta-analysis of randomised controlled trials

ABSTRACT

Fibromyalgia is a highly heterogeneous condition, but the most common symptoms are widespread pain, fatigue, poor sleep, and low mood. Nonpharmacological interventions are recommended as first-line treatment of fibromyalgia. However which interventions are effective for the different symptoms is not well understood. The objective of this study was to assess the efficacy of nonpharmacological interventions on symptoms and disease-specific quality of life. Seven databases were searched from their inception until June 1, 2020. Randomised controlled trials comparing any nonpharmacological intervention to usual care, waiting list, or placebo in people with fibromyalgia aged >16 years were included without language restriction. Fibromyalgia Impact Questionnaire (FIQ) was the primary outcome measure. Standardised mean difference and 95% confidence interval were calculated using random effects model. The risk of bias was evaluated using the modified Cochrane tool. Of the 16,251 studies identified, 167 randomised controlled trials (n = 11,012) assessing 22 nonpharmacological interventions were included. Exercise, psychological treatments, multidisciplinary modality, balneotherapy, and massage improved FIQ. Subgroup analysis of different exercise interventions found that all forms of exercise improved pain (effect size [ES] -0.72 to -0.96) and depression (ES -0.35 to -1.22) except for flexibility exercise. Mind-body and strengthening exercises improved fatigue (ES -0.77 to -1.00), whereas aerobic and strengthening exercises improved sleep (ES -0.74 to -1.33). Psychological treatments including cognitive behavioural therapy and mindfulness improved FIQ, pain, sleep, and depression (ES -0.35 to -0.55) but not fatigue. The findings of this study suggest that nonpharmacological interventions for fibromyalgia should be individualised according to the predominant symptom.

Efficacy of Acupuncture, Intravenous Lidocaine, and Diet in the Management of Patients with Fibromyalgia: A Systematic Review and Network Meta-Analysis

Introduction: This network meta-analysis aimed to assess the efficacy of acupuncture, intravenous lidocaine, and diet compared with other comparators such as physiotherapy and sham/placebo in fibromyalgia patients. Materials and Methods: We searched Embase, PubMed, Scopus, and Web of Science for relevant studies till September 2021. The included studies were randomized controlled clinical trials. For the network meta-analysis, we used the R software. Results: There were 23 included RCTs. The total sample size was 1409 patients. Compared with the sham/placebo group, the network analysis showed the highest improvement in the quality of life in the acupuncture group standardized mean difference (SMD) = −10.28, 95%-CI [−14.96; −5.59]), and then in the physiotherapy group (SMD = −7.48, 95%-CI [−14.72; −0.23]). For the pain, there was a significant reduction with acupuncture (SMD = −1.69, 95%-CI [−2.48; −0.89]), compared with sham/placebo. Regarding depression, it showed a significant reduction with acupuncture (SMD = −9.64, 95%-CI [−16.13; −3.14]) compared with sham/placebo. Finally, for stiffness, it showed no significant differences in the stiffness between acupuncture (SMD = −8.52, 95%-CI [−20.40; 3.36]), fluoxetine (SMD = −6.52, 95%-CI [−29.65; 16.61]), and physiotherapy (SMD = −4.64, 95%-CI [−22.83; 13.54]) compared with sham/placebo. Conclusions: The acupuncture showed a significant effect in the management of fibromyalgia patients. It reduced pain, depression, and enhanced the quality of life. While physiotherapy showed a significant improvement in the quality of life only. In contrast, intravenous lidocaine and diet showed no significant differences when compared with sham/placebo.

An Assessment of Naturopathic Treatments, Health Concerns, and Common Comorbid Conditions in Fibromyalgia Patients: A Retrospective Medical Record Review

Background: Fibromyalgia (FM) is characterized by chronic pain, with allodynia and hyperalgesia being the most common signs. Many patients with FM explore, express interest, and use complementary and alternative medicine to help manage symptoms and improve quality of life. However, little is known about the clinical recommendations provided by naturopathic doctors (NDs). Objective: To describe trends in assessment and treatment of patients with FM by NDs. Methods: Retrospectively, medical records of 200 patients with the FM ICD-10 code were reviewed from the Robert Schad Naturopathic Clinic. Of these records, 70 met inclusion criteria and were further analyzed. Comorbid conditions, health concerns, physical and psychological examinations, and treatment were recorded. Patients were excluded if informed consent for research was not signed. The project was approved by the Research Ethics Board of the Canadian College of Naturopathic Medicine. Results: Seventy patients met criteria and were included in the current analysis. Most patients identified as female (96%). Vitamin D (57%), magnesium (54%), omega-3 fish oil (53%), acupuncture by an acupuncturist (53%) or an ND (40%), B12 orally or by injection (40%), and probiotics (40%) were highly utilized treatments. A past/current medical history of digestive complaints (64%) and depression/mental illness (63%) were common comorbidities, alongside a history of arthritic conditions (53%) and anxiety (43%). A family history of arthritic conditions (47%) was also prevalent. The Widespread Pain Index and Symptom Severity tool (43%) was used to assess pain and other symptoms. No adverse effects of treatment were readily identifiable. Conclusion: Findings from this study reveal elements of both consistency and variability in the treatment recommendations from NDs in a teaching clinic environment. Future research that assesses or compares treatment recommendations for FM in other settings may be informative to better understand health services, the nature of individualized care, and patient experiences.

Effect of Acupuncture on Pain, Fatigue, Sleep, Physical Function, Stiffness, Well-Being, and Safety in Fibromyalgia: A Systematic Review and Meta-Analysis

Purpose

Fibromyalgia (FM) is a syndrome characterized by widespread pain, which caused huge economic and social burden. Acupuncture is often used to manage chronic pain. However, the efficacy of acupuncture in FM is still controversial. This study aimed to systematically review the effects of acupuncture on pain, fatigue, sleep quality, physical function, stiffness, well-being, and safety in FM.

Methods

We searched databases including PubMed, Embase, the Cochrane Library, Wanfang Database, Chongqing Weipu, and the China National Knowledge Infrastructure from inception to September 2021. Eligible studies included randomized or quasi-randomized controlled studies of acupuncture in patients with FM. Quantitative analysis was conducted using RevMan 5.3 software, and risk assessment was performed according to the Cochrane collaboration tool. Safety was quantitatively analyzed.

Results

A total of 13 articles were searched, of which 12 were analyzed quantitatively. Our meta-analysis found that acupuncture could alleviate pain (SMD: −0.42, 95% CI, −0.66, −0.17, P<0.001, I²=58%) and improve well-being (SMD: −0.86, 95% CI, −1.49, 0.24, P=0.007, I²=85%) at post-treatment. In addition, acupuncture showed long-term effects on reducing pain (P=0.03) and improving well-being (P<0.001). No evidence that acupuncture works on fatigue, sleep quality, physical function, or stiffness was found. No serious adverse events were detected in acupuncture treatment.

Conclusion

Moderate quality of evidence supports acupuncture in reducing pain in patients with FM. Therefore, acupuncture is recommended as a treatment for FM.

Effectiveness of non-pharmacological conservative therapies in adults with fibromyalgia: A systematic review of high-quality clinical trials

BACKGROUND

Fibromyalgia is a chronic condition characterized by generalized pain. Several studies have been conducted to assess the effects of non-pharmacological conservative therapies in fibromyalgia.

OBJECTIVE

To systematically review the effects of non-pharmacological conservative therapies in fibromyalgia patients.

METHODS

We searched MEDLINE, Cochrane library, Scopus and PEDro databases for randomized clinical trials related to non-pharmacological conservative therapies in adults with fibromyalgia. The PEDro scale was used for the methodological quality assessment. High-quality trials with a minimum score of 7 out of 10 were included. Outcome measures were pain intensity, pressure pain threshold, physical function, disability, sleep, fatigue and psychological distress.

RESULTS

Forty-six studies met the inclusion criteria. There was strong evidence about the next aspects. Combined exercise, aquatic exercise and other active therapies improved pain intensity, disability and physical function in the short term. Multimodal therapies reduced pain intensity in the short term, as well as disability in the short, medium and long term. Manual therapy, needling therapies and patient education provided benefits in the short term.

CONCLUSIONS

Strong evidence showed positive effects of non-pharmacological conservative therapies in the short term in fibromyalgia patients. Multimodal conservative therapies also could provide benefits in the medium and long term.

Efficacy of acupuncture in the treatment of fibromyalgia

Purpose of Review

Fibromyalgia is a highly prevalent chronic pain syndrome that affects up to 4% of the population and causes significant morbidity and disability, with an increasing associated cost. Though many approaches for treatment have been tested, therapy regimens are still elusive, and efficacy is limited. This review summarizes the background of fibromyalgia and acupuncture and reviews the latest and seminal literature discussing the application of acupuncture in fibromyalgia.

Recent Findings

Fibromyalgia is hard to treat, owing both to its chronicity and poorly understood pathophysiology and etiology. Current treatments target symptoms primarily, and few attempt to address the source. Efficacious treatment requires long-term treatment by a multidisciplinary team. Though several treatments exist, they still fall short with a substantial number of patients. Acupuncture, a form of integrative medicine, has been a part of traditional Chinese medication for generations. Evidence shows that it effectively treats different kinds of pain conditions, including migraines and chronic musculoskeletal pain. Recent studies showed evidence to support its use in fibromyalgia. Clinical trials studying acupuncture in fibromyalgia have shown improvement in pain, quality of sleep, and quality of life, though the quality of evidence is mainly low to medium. Several studies were not able to provide evidence to support real over sham acupuncture. Weighing the overall evidence paints a picture of mixed results between equivocal results to positive. In analyzing these results, one must also consider publication bias supporting the dissemination of positive results.

Summary

An increasing number of studies support the utilization of acupuncture for the treatment of fibromyalgia. Though no head-to-head comparison was able to show the superiority of acupuncture to other therapies, mounting evidence supports its use as part of multimodal approaches to treatment with additive efficacy to traditional therapy. Further research will likely provide data on effective regimens and combination therapies.

Peripheral and Spinal Mechanisms Involved in Electro-Acupuncture Therapy for Visceral Hypersensitivity

One of the important characteristic features of clinically significant gastrointestinal disorders is visceral hypersensitivity (VH). Pain sensitization or VH is a big challenge for clinicians and becomes a very thorny work in clinical practices; the therapeutic efficacy for VH results in limited success. A popular second therapy that is being approved for the induction of analgesia and attenuates VH with fewer side effects includes electro-acupuncture (EA). Different peripheral and spinal neurological chemicals, including neurotransmitters, neuropeptides, and cytokines, and different signaling pathways were associated with EA treatment in VH. Despite the higher acceptance of EA, the underlying mechanism still needs to be further explored. In this paper, we review the available literature to find the peripheral and spinal mechanisms involved in EA to relieve VH.

The Therapeutic Effects of Acupuncture and Electroacupuncture on Cancer-related Symptoms and Side-Effects

In addition to cancer-related death, malignant progression also leads to a series of symptoms and side-effects, which would detrimentally affect cancer patients' the quality of life, adversely influence their adherence to treatments, and, therefore, negatively affect their long-term survival. Acupuncture and electroacupuncture (EA), as two classic treatment methods in traditional Chinese medicine, have been widely employed to cure various diseases. Recently, the clinical application of acupuncture and EA in cancer patients has received great attention. In this review, we summarized the clinical application of acupuncture and EA in alleviating the cancer symptoms, reducing the cancer treatment-related side-effects, and relieving the cancer pain. The symptoms and side-effects discussed in this review include fatigue, insomnia, chemotherapy-associated dyspepsia syndrome (CADS), pain, xerostomia, and anxiety and depression. The underlying mechanisms of the therapeutic effects of acupuncture and EA might be related to the regulation of the mitochondrial function, coordination of the activity of the nervous system, adjustment of the production of neurotransmitters, and alleviation of the immune responses. In conclusion, acupuncture and EA have been proved to be beneficial for cancer patients. More research, however, is required to clarify the potential mechanisms behind acupuncture and EA for widespread adoption in clinical application.

Pain Changes Induced by Acupuncture in Single Body Areas in Fibromyalgia Syndrome: Results from an Open-Label Pragmatic Study

To date, there is considerable evidence of the effectiveness of acupuncture in fibromyalgia syndrome (FM). However, it is not known in which body areas acupuncture is more effective. The objective of this study was to assess the improvements of pain induced by acupuncture in single body areas in patients with FM. In this open-label pragmatic study, FM patients in a state of high disease severity were consecutively enrolled and treated with a course of 8 weekly sessions of manual acupuncture. Patients were assessed with the Self-Administered Pain Scale (SAPS) of the Fibromyalgia Assessment Status at baseline and at the end of eight acupuncture sessions. Acupuncture sessions were all conducted with the same acupuncture formula (LV3, SP6, ST36, LI4, CV6, CV12, Ex-HN-3, and GV20) in each session and in each patient. Ninety-six FM patients completed the course of treatment. All the 16 body areas assessed by SAPS showed improvement in pain. A statistically significant improvement was achieved in 12 of the 16 body areas investigated, with the best results in abdomen and forearms (p = 0.001), while the worst results were registered for neck (p = 0.058), chest (p = 0.059), left buttock (p = 0.065), and right thigh (p = 0.052). The treatment has also shown significant effectiveness in improving fatigue and sleep quality (p < 0.0001). Acupuncture has a beneficial effect on pain in all body areas in FM patients with high disease severity, with the greatest effects in the abdominal region and in the forearms, allowing a personalization of the treatment.

Diagnostic Challenges and Management of Fibromyalgia

The World Health Organization regards chronic pain to be a public health concern. In clinical medicine, fibromyalgia (FM) is the most prevalent chronic widespread pain disease. In terms of impairment, consumption of health and social resources, and impact on primary and speciality care systems, it has reached worrisome proportions. This disease is frequently managed by primary care providers. Because of its intricacy, fibromyalgia diagnosis and treatment can be difficult. Fibromyalgia is a controversial condition. It might appear ill-defined in comparison to other pain conditions, with no clear knowledge of pathophysiology and hence no particular targeted therapy. This invariably sparks debates and challenges. There is no obvious cut-off point that distinguishes FM from non-FM. The diagnosis of fibromyalgia has been complicated by several factors, including patients' health-seeking behaviour, symptom identification, and physician labelling of the disease. Fibromyalgia is currently considered a centralized pain condition, according to research that has improved our understanding of its etiopathology. A multidisciplinary strategy combining pharmacological and non-pharmacological therapies based on a biopsychosocial paradigm can result in effective therapy. Cultural and psychosocial variables appear to be a recent development in fibromyalgia, and they appear to have a larger influence on physician diagnosis than severe symptom levels in FM patients. Although physicians rely on FM criteria as the only way to classify FM patients in research and clinical settings, some crucial elements of the diagnostic challenge of fibromyalgia remain unsolved - invalidation, psychosocial variables, and diverse illness manifestation are some examples. Beyond the existing constructional scores, physicians' judgment gained in real communicative contexts with patients, appears to be the only dependable route for a more accurate diagnosis for fibromyalgia. We have performed an exhaustive review of the literature using the keywords "Fibromyalgia", "challenges" and "diagnosis" in PubMed and Google Scholar indexes up to September 2021. This article aims to examine the causes, diagnosis, and current treatment protocols of FM, as well as discuss some continuing debates and diagnostic challenges which physicians face in accurately diagnosing fibromyalgia.

Effects of Physiotherapy vs. Acupuncture in Quality of Life, Pain, Stiffness, Difficulty to Work and Depression of Women with Fibromyalgia: A Randomized Controlled Trial

BACKGROUND

Fibromyalgia is a chronic clinical condition characterized by pain and other associated symptoms that have a negative impact on the quality of life of the affected person. The objective of this study was to assess the effectiveness of a core stability training physiotherapy program compared to an acupuncture treatment on quality of life, pain, joint stiffness, difficulty to work and depression of women with fibromyalgia.

METHODS

This was a single-blind, randomized clinical controlled trial. Women with fibromyalgia were randomized to a core stability physiotherapy program group (n = 45), an acupuncture treatment group (n = 45) and a control group (n = 45) for 13 weeks. Measurements were taken at baseline (week 0), post-intervention (week 6) and at follow-up (week 13). The primary outcome measure was quality of life (Spanish Fibromyalgia Impact Questionnaire). The secondary outcome measures were pain, joint stiffness, difficulty to work and depression (Visual Analogue Scale).

RESULTS

In total, 103 participants completed the study. The results, from a descriptive perspective, showed improvements in all the outcome measures in both intervention groups (physiotherapy and acupuncture) at weeks 6 and 13 in relation to week 0 and in comparison to the control group. Only the difficulty to work measure in the acupuncture group showed a slight decrease at week 13. In particular, mean (±SD) Spanish Fibromyalgia Impact Questionnaire score at 6 weeks was 62.89 ± 16.91 for the physiotherapy group, 62.5 ± 18.09 for the acupuncture group and 67.45 ± 17.07 for the control group. However, these improvements were not statistically significant.

CONCLUSION

Core stability-based physiotherapy and acupuncture showed non-significant improvements in quality of life, pain, joint stiffness, difficulty to work and depression in women with fibromyalgia.

Acupuncture Effects on Blood Parameters in Patients with Fibromyalgia

Objectives: Acupuncture reduces pain and symptoms significantly in fibromyalgia (FM). Currently, there are no laboratory markers to monitor treatment effectiveness. This study measured differences in biomarkers and test scores of patients with FM before and after acupuncture. Materials and Methods: This retrospective study involved 102 females previously diagnosed with FM at a rheumatology clinic, who had received various medical treatments. Patients who did not receive treatment for symptom management of FM for the last 3 months were included. C-reactive protein (CRP) and complete blood count (CBC), and Fibromyalgia Impact Questionnaire (FIQ) visual analogue scale (VAS) scores before and after the acupuncture sessions were obtained from the patients' files. Neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), mean platelet volume/lymphocyte ratio (MPVLR), monocyte/lymphocyte ratio (MLR) were calculated. It was determined if there were statistically differences in these parameters. A correlation analysis was also performed. Results: There were statistically significant decreases in CRP, NLR, PLR, and MPVLR values as well as VAS and FIQ scores in the patient post acupuncture. NLR was positively correlated with disease impact and CRP after completion of acupuncture. Conclusions: The decreasing tendency of the markers from the CBC after acupuncture were correlated with FM impact. These results show effects of acupuncture on biomarkers. Prospective randomized controlled trials on how acupuncture affects blood parameters in patients with FM are needed.

The gut-brain axis and beyond: Microbiome control of spinal cord injury pain in humans and rodents

Spinal cord injury (SCI) is a devastating injury to the central nervous system in which 60 to 80% of patients experience chronic pain. Unfortunately, this pain is notoriously difficult to treat, with few effective options currently available. Patients are also commonly faced with various compounding injuries and medical challenges, often requiring frequent hospitalization and antibiotic treatment. Change in the gut microbiome from the "normal" state to one of imbalance, referred to as gut dysbiosis, has been found in both patients and rodent models following SCI. Similarities exist in the bacterial changes observed after SCI and other diseases with chronic pain as an outcome. These changes cause a shift in the regulation of inflammation, causing immune cell activation and secretion of inflammatory mediators that likely contribute to the generation/maintenance of SCI pain. Therefore, correcting gut dysbiosis may be used as a tool towards providing patients with effective pain management and improved quality of life.

Effectiveness of Invasive Techniques in Patients with Fibromyalgia: Systematic Review and Meta-Analysis

OBJECTIVE

To attain a synthesis of the evidence on the effectiveness of invasive techniques in patients with fibromyalgia, through systematic review and meta-analysis and by assessing the methodological quality of the studies considered.

METHODS

A systematic review and meta-analysis were carried out as defined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The bibliographic research was carried out in the PEDro, Cochrane, PubMed, Science Direct, Web of Science, Google Academics, Dialnet, and Scielo databases from September through December of 2018.

RESULTS

Results show that invasive techniques produce a significant decrease in the pain, the impact of fibromyalgia and in the pain pressure threshold (standardized mean difference [95% confidence interval]: -0.94 [-1.44, -0.44], P of global effect= 0.0002; -0.99 [-1.69, -0.29], P of global effect= 0.006; and 0.31 [0.02, 0.61], P of global effect = 0.04, respectively). Lastly, a significant increase was observed in the quality-of-life variable after intervention (0.84 [0.30, 1.38], P of global effect = 0.002).

CONCLUSIONS

Invasive techniques are considered effective for pain relief, as well as for producing a short-term increase in the pain pressure threshold, an improvement in quality of life, and a decrease in the impact of fibromyalgia.

Effects of Acupressure on Pain, Flexibility, and Substance P in Middle-Age Women with Chronic Neck Pain

Introduction: Acupressure is known to be effective for some types of chronic pain. However, the effect of acupressure on chronic neck pain has not been investigated. Accordingly, the authors aimed to evaluate effects of the 4-week acupressure treatment on pain, neck function, and substance P in women with chronic neck pain. Methods: The acupressure treatment was performed two times a week for 4 weeks in an acupressure group (n = 24), meanwhile a control group (n = 26) was untreated. Before and after intervention, pain intensity and physical disability were measured by visual analogue scale (VAS) and neck disability index (NDI), respectively. In addition, cervical range of motion (CROM) and serum substance P were evaluated. Results: Results of two-way analysis of variance with repeated measures revealed that time × group interactions were significant in all outcomes (all p < 0.001) except substance P. These results indicate that after 4 weeks, VAS and NDI significantly decreased in the acupressure group compared with those changes in the control group. The CROM values for six cervical movements significantly increased in the acupressure group compared with those changes in the control group. Serum substance P did not change significantly in both groups. However, when the pre- and postintervention data from all subjects were pooled, substance P was significantly correlated with VAS (r = 20; p < 0.05; n = 100). Conclusions: The 4-week acupressure intervention showed significant reduction in pain and improvement in neck disability and flexibility, suggesting that acupressure intervention is an effective treatment for chronic neck pain. This study was registered with the Korean Clinical Trial Registry and WHO Clinical Trial Registry (KCT0005363).

Fibromyalgia: Recent Advances in Diagnosis, Classification, Pharmacotherapy and Alternative Remedies

Fibromyalgia (FM) is a syndrome that does not present a well-defined underlying organic disease. FM is a condition which has been associated with diseases such as infections, diabetes, psychiatric or neurological disorders, rheumatic pathologies, and is a disorder that rather than diagnosis of exclusion requires positive diagnosis. A multidimensional approach is required for the management of FM, including pain management, pharmacological therapies, behavioral therapy, patient education, and exercise. The purpose of this review is to summarize the recent advances in classification criteria and diagnostic criteria for FM as well as to explore pharmacotherapy and the use of alternative therapies including the use of plant bioactive molecules.

Acupuncture decreased the risk of stroke among patients with fibromyalgia in Taiwan: A nationwide matched cohort study

BACKGROUND

The aim of this study was to investigate the effectiveness of acupuncture in decreasing the risk of stroke in patients with fibromyalgia.

METHODS

We enrolled patients who was newly diagnosed as having fibromyalgia between 1 January, 2000 and 31 December, 2010 from the Taiwanese National Health Insurance Research Database. The claim data for both the acupuncture cohort and non-acupuncture cohort were assessed from the index date to 31 December, 2013. A Cox regression model adjusted for age, sex, comorbidities, and drugs use was used to compare the hazard ratios of the two cohorts. The cumulative incidence of stroke was estimated by using the Kaplan-Meier method.

RESULTS

After performing a propensity score matching with a 1:1 ratio, there were 65,487 patients in the acupuncture and non-acupuncture cohorts with similar distributions in the baseline characteristics. The cumulative incidence of stroke was significantly lower in the acupuncture cohort (log-rank test, p < 0.001). In the follow-up period, 4,216 patients in the acupuncture cohort (11.01 per 1000 person-years) and 6,849 patients in the non-acupuncture cohort (19.82 per 1000 person-years) suffered from stroke (adjusted HR 0.53, 95% CI 0.51-0.55). Acupuncture favorably affected the incidence of stroke regardless of the patient's age, sex, comorbidities, and conventional drug use.

CONCLUSIONS

Our study found that acupuncture might have a beneficial effect on reducing the risk of stroke in patients with fibromyalgia in Taiwan. Additional clinical and basic science studies are warranted.

Acupuncture and Chronic Musculoskeletal Pain

PURPOSE OF REVIEW

Chronic musculoskeletal pain (CMP) attributable to conditions such as osteoarthritis, rheumatoid arthritis, fibromyalgia, and chronic low back pain is the most common cause of disability globally, for which no effective remedy exists. Although acupuncture is one of the most popular sensory stimulation therapies and is widely used in numerous pain conditions, its efficacy remains controversial. This review summarizes and expands upon the current research on the therapeutic properties of acupuncture for patients with CMP to better inform clinical decision-making and develop patient-focused treatments.

RECENT FINDINGS

We examined 16 review articles and 11 randomized controlled trials published in the last 5 years on the clinical efficacy of acupuncture in adults with CMP conditions. The available evidence suggests that acupuncture does have short-term pain relief benefits for patients with symptomatic knee osteoarthritis and chronic low back pain and is a safe and reasonable referral option. Acupuncture may also have a beneficial role for fibromyalgia. However, the available evidence does not support the use of acupuncture for treating hip osteoarthritis and rheumatoid arthritis. The majority of studies concluded the superiority of short-term analgesic effects over various controls and suggested that acupuncture may be efficacious for CMP. These reported benefits should be verified in more high-quality randomized controlled trials.

The role of acupuncture in the treatment of chronic pain

Acupuncture is a practice based on traditional Chinese medicine, in which needles are used to restore the body's internal balance. Recently, there has been growing interest in the use of acupuncture for various pain conditions. Acupuncture's efficacy in five pain conditions-low back pain (LBP), migraines, fibromyalgia, neck pain, and abdominal pain-was evaluated in this evidence-based, comprehensive review. Based on the most recent evidence, migraine and fibromyalgia are two conditions with the most favorable outcomes after acupuncture. At the same time, abdominal pain has the least evidence for the use of acupuncture. Acupuncture is efficacious for reducing pain in patients with LBP, and for short-term pain relief for those with neck pain. Further research needs to be done to evaluate acupuncture's efficacy in these conditions, especially for abdominal pain, as many of the current studies have a risk of bias due to lack of blinding and small sample size.

Acupuncture for menopausal symptoms in Chinese women: a systematic review

Menopause-related symptoms are common problems of middle-aged women that can seriously affect their quality of life. Menopausal hormone therapy (MHT) for climacteric symptoms is the first choice recommended by the International Menopause Society and likewise by other societies and institutions covering this field. However, non-hormonal therapies can be an alternative effective option, especially for women who are not suitable for MHT. Acupuncture is one of the most important methods. With deepening experience of the use of traditional Chinese acupuncture and moxibustion in the improvement of menopause symptoms, more clinical evidence has been obtained to support the effectiveness and safety of this treatment concept that is very often used in China. This review summarizes the evidence for effective treatment of climacteric complaints by acupuncture in recent years, shares the clinical experience of the authors of this review, all of whom head or work in units with daily large numbers of outpatients, and includes, in particular, results from studies performed in the Department of Acupuncture--Moxibustion of Tsinghua University Chuiyangliu Hospital, Beijing, China. In addition, there is a summary about the safety of acupuncture treatment in traditional Chinese medicine.

Comparison between Acupuncture and Nutraceutical Treatment with Migratens® in Patients with Fibromyalgia Syndrome: A Prospective Randomized Clinical Trial

OBJECTIVES

Fibromyalgia syndrome (FMS) is a chronic clinical condition characterized by pain, fatigue, altered sleep, and cognitive disturbances. The purpose of this study was to compare two alternative treatments (nutraceutical and acupuncture) in FMS patients through a randomized clinical trial.

RESEARCH METHODS

A total of 60 FMS female patients were randomized for treatment with a nutritional combination containing coenzyme Q10, vitamin D, alpha-lipoic acid, magnesium, and tryptophan (Migratens® Group) or acupuncture treatment (Acupuncture Group) performed according the principles of traditional Chinese medicine (TCM), both for 3 months. Changes in pain and in quality of life (QoL) measured with a Fibromyalgia Impact Questionnaire Score-Revised (FIQ-R) and the Fibromyalgia Severity Scale (FSS) were performed at 1, 3, and 6 months after the start of treatments.

RESULTS

A total of 55 patient completed the study (21 in the Migratens® Group and 34 in the Acupuncture Group). Migratens® treatment shows a statistically significant reduction of pain 1 month after the start of therapy (T1, p = 0.025), strengthened after 3 months with maintenance of treatment (p = 0.012). The efficacy in reducing pain was apparent in the Acupuncture Group at all post-treatment determinations and at follow-up (T1 and T2 p = <0.001). Regarding QoL, improvement in FIQ-R and FSS values was revealed in both groups.

CONCLUSION

The nutraceutical approach with Migratens® seems to be an effective option to for patients with FMS. Our experience confirmed also the validity of acupuncture in these patients. Considering the complexity of the management of FMS patients, our results suggest a cyclical and sequential, or even concurrent treatment with different approaches, to improve the efficacy and the compliance of patients to long-term treatment.

Acupuncture for Fibromyalgia: An Open-Label Pragmatic Study on Effects on Disease Severity, Neuropathic Pain Features, and Pain Catastrophizing

The treatment of fibromyalgia syndrome (FMS) is still far from being optimally coded, and pharmacological strategies are often unsatisfactory. Acupuncture plays a role among nonpharmacological intervention approaches; however, there is still no clarity as to when to integrate it into therapy. The objective of this study is to explore the role of acupuncture, in terms of efficacy on main disease severity measures and pain features, in patients with nonresponsive disease, defining nonresponsive FMS characterized by a revised Fibromyalgia Impact Questionnaire (FIQ-R) ≥39 and a Patient Health Questionnaire 15-item (PHQ15) ≥5 despite optimal drug therapy. Patients were treated with weekly sessions, for a total of eight acupuncture sessions. At the baseline and at the end of the treatment cycle, a comprehensive clinical evaluation was carried out to evaluate improvements in terms of disease severity and impact on neuropathic pain features (measured with the painDETECT questionnaire (PDQ)) and pain catastrophizing (measured with the Pain Catastrophizing Scale (PCS)). At the end of the eight-week treatment, patients experienced a significant improvement in all evaluated parameters (for FIQ-R, PDQ, and PHQ15 p < 0.0001, for PCS p=0.001). Of particular note is the effectiveness on manifestations that are difficult to treat such as neuropathic pain features and on negative psychological perceptions such as pain catastrophizing. It can be stated that acupuncture can be proposed also in phases of high severity of disease. Intervention with multimodal strategies, including acupuncture, could be of great benefit to patients.

Classic Chinese Acupuncture versus Different Types of Control Groups for the Treatment of Chronic Pain: Review of Randomized Controlled Trials (2000-2018)

OBJECTIVE

To review the effectiveness of classic Chinese acupuncture in the treatment of chronic pain by comparing treatment groups with different types of control groups in accordance with the newly published guidelines for systematic reviews.

METHODS

We searched EMBASE, PubMed, and the Cochrane Central Register of Controlled Trials databases from 2000 to 2018. We included randomized controlled trials that included acupuncture as the sole treatment or as an adjunctive treatment for chronic pain. The outcome was pain intensity measured by the visual analogue scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale, 11-point numeric rating scale (NRS), and other tools. Two researchers conducted the study selection, data extraction, and quality assessment processes independently. Disagreements were solved by discussion and reanalysis of the data. The quality of all included studies was evaluated using the CBNG (the Cochrane Back and Neck Group) and the STRICTA (Standards for Reporting Interventions in Controlled Trials of Acupuncture) checklists.

RESULTS

Sixty-one studies were fully analyzed and ranked based on the newest STRICTA and CBNG standards. We found good evidence that receiving acupuncture is better than not receiving treatment or being placed on a waiting list and reasonable evidence that it is better than conventional or usual care. Limited evidence was found regarding placebo treatments that involve the expectation of needling (real or fake).

CONCLUSION

Sham acupuncture may not be appropriate as a control intervention for assessing the effectiveness of acupuncture. Acupuncture effectiveness in controlling chronic pain is still limited due to the low quality of the studies published.

Cough Suppression during Flexible Bronchoscopy Using Transcutaneous Electric Acupoint Stimulation: A Randomized Controlled Study

Background and Objective. Transcutaneous electric acupoint stimulation (TEAS) is recommended for its sedative and analgesic effects. We sought to evaluate the effect of TEAS on cough suppression during flexible bronchoscopy (FB) and explore the underlying mechanism. Methods. In this single-center, randomized, single-blind, parallel-controlled study, we randomized 100 patients scheduled for FB into two equal groups treated with or without TEAS (TEAS group and control group). Patients in the TEAS group received 30 min of stimulation at the Hegu (LI4), Neiguan (PC6), and Lieque (LU7) points before FB. The control group underwent the same procedure, but without stimulation. The primary outcome was the intraoperative cough score determined by the bronchoscopist. The secondary outcomes were patient-reported discomfort scores and other procedural parameters. Results. Compared with the controls, patients who received TEAS preconditioning had lower cough scores (P=0.0027) and requirement of lidocaine and fentanyl (P < 0.05) and significantly higher postprocedural plasma β-endorphin levels (P=0.0367). There were no intergroup differences in discomfort scores, midazolam dosage, rate of premature termination, oxygen requirement, sedation level, airway assistance, oxygen saturation, lowest oxygen saturation level, heart rate, plasma substance-P levels, and rate of complications after 24 h. The total procedure duration, time for passage of the bronchoscope through the vocal cords, and systolic and diastolic blood pressure levels were less in the TEAS group than in the control group (P=0.033, 0.039 and <0.05, respectively). Conclusion. The combination of midazolam and TEAS was superior to midazolam alone for cough suppression during FB, probably due to increased plasma β-endorphin levels. This trial is registered with ChiCTR1800016612 at chictr.org.cn/index.aspx.

Comparing Verum and Sham Acupuncture in Fibromyalgia Syndrome: A Systematic Review and Meta-Analysis

OBJECTIVES

Acupuncture is often used for relieving symptoms of fibromyalgia syndrome (FMS). Our aim is to ascertain whether verum acupuncture is more effective than sham acupuncture in FMS.

METHODS

We collected RCTs to investigate the effects of verum acupuncture and sham acupuncture on pain, sleep quality, fatigue, and general status in FMS patients. The databases used for data retrieval were PubMed, Central Cochrane, EMBASE, PsycINFO, CNKI, VIP, OASIS, KoreaMed, and RISS. Selection/exclusion from the retrieved records was performed according to prespecified criteria, and the final selected records were assessed according to the Cochrane risk of bias tool. The results of the included trials were synthesized on the basis of outcomes, and subgroup analysis depended on the type of add-on sham acupuncture that was performed.

RESULTS

Ten RCTs (690 participants) were eligible, and eight RCTs were eventually included in the meta-analysis. The synthesis showed a sizable effect of verum acupuncture compared with sham acupuncture on pain relief (standardized mean difference (SMD) -0.49, Z = 3.26, P=0.001; I 2 = 59%), improving sleep quality (SMD -0.46, Z = 3.24, P=0.001; I 2 = 0%), and reforming general status (SMD -0.69, Z = 6.27, P < 0.00001; I 2 = 4%). However, efficacy on fatigue was insignificant (SMD -0.10, Z = 0.51, P=0.61; I 2 = 46%). When compared with a combination of simulation and improper location of needling, the effect of verum acupuncture for pain relief was the most obvious.

CONCLUSIONS

Verum acupuncture is more effective than sham acupuncture for pain relief, improving sleep quality, and reforming general status in FMS posttreatment. However, evidence that it reduces fatigue was not found.

What Is the Appropriate Acupuncture Treatment Schedule for Chronic Pain? Review and Analysis of Randomized Controlled Trials

Background

Acupuncture is widely used for the treatment of chronic pain. Different protocols of acupuncture practice exist and lack agreement on the optimal schedule of acupuncture treatment.

Objective

To review the appropriate acupuncture treatment schedule for chronic pain.

Methods

Embase, Pubmed, Cochrane Central Register of Controlled Trials, and reference lists were searched from 2009 to 2018 to identify randomized controlled trials of acupuncture for chronic pain conditions. We collected factors of treatment schedule (D, duration of each treatment session; N, number of treatment sessions; T, total duration of treatment in weeks) from each of the trials, and the linear regression analysis with real pain relief rate (both treatment and follow-up) was performed. Furthermore, we recommend the concept of “DOSE” and frequency (F) to evaluate the dose and frequency effect of acupuncture.

Results

Twenty-four trials with a total number of 3461 patients met the inclusion criteria. Of these, data from 23 studies were available for analysis. Firstly, the results showed that follow-up pain relief rate was decreased slightly with the increase of the duration of each session and DOSE (r=-0.3414 and r=-0.3246, respectively), but those two factors had no correlation with the pain relief rate after treatment. Secondly, it showed that either lower frequency with 2 sessions/week and higher frequency greater than 2 sessions/week or DOSE of 30 mins/week can achieve higher pain relief rate after treatment. Thirdly, we found the rate of pain relief remained at a high level greater than 20% up to 18 weeks after the treatment, and then it dropped sharply below 10% with the follow-up extended. A positive relationship was found between study score and pain relief both in treatment and follow-up (r=0.4654 and r=0.3046, respectively).

Conclusions

The effect of acupuncture varies greatly with the different schedules of acupuncture, so it is necessary to review and choose the appropriate schedule. Although the current work is based on a limited number of trials, the findings suggest that acupuncture has a dose and frequency effect presenting within a certain range, which would have considerable implications for the design and interpretation of clinical trials. More high-quality randomized controlled trials on acupuncture schedule research were needed for providing more definitive evidence.

Nociceptin/orphanin FQ receptor modulates painful and fatigue symptoms in a mouse model of fibromyalgia

Generalized pain and fatigue are both hallmarks of fibromyalgia, a syndrome with an indefinite etiology. The treatment options for fibromyalgia are currently limited, probably because of its intricate pathophysiology. Thus, further basic and clinical research on this condition is currently needed. This study investigated the effects of nociceptin/orphanin FQ (N/OFQ) receptor (NOPr) ligands and the modulation of the NOP system in the preclinical mouse model of reserpine-induced fibromyalgia. The effects of administration of the natural agonist N/OFQ and the selective NOPr antagonists (UFP-101 and SB-612111) were evaluated in fibromyalgia-related symptoms in reserpine-treated mice. The expression of prepronociceptin/orphanin FQ and NOPr was assessed in central and peripheral sites at different time points after reserpine administration. Nociceptin/orphanin FQ displayed dual effects in the behavioral changes in the reserpine-elicited fibromyalgia model. The peptide NOPr antagonist UFP-101 produced analgesic and antifatigue effects, by preventing alterations in brain activity and skeletal muscle metabolism, secondary to fibromyalgia induction. The nonpeptide NOPr antagonist SB-612111 mirrored the favorable effects of UFP-101 in painful and fatigue alterations induced by reserpine. A time-related up- or downregulation of prepronociceptin/orphanin FQ and NOPr was observed in supraspinal, spinal, and peripheral sites of reserpine-treated mice. Our data shed new lights on the mechanisms underlying the fibromyalgia pathogenesis, supporting a role for N/OFQ-NOP receptor system in this syndrome.

Central and Peripheral Mechanism of Acupuncture Analgesia on Visceral Pain: A Systematic Review

Background/Aims

Despite the wide use of acupuncture for the management of visceral pain and the growing interest in the pathophysiology of visceral pain, there is no conclusive elucidation of the mechanisms behind the effects of acupuncture on visceral pain. This systematic review aims to provide an integrative understanding of the treatment mechanism of acupuncture for visceral pain.

Methods

Electronic and hand searches were conducted to identify studies that involved visceral pain and acupuncture.

Results

We retrieved 192 articles, out of which 46 studies were included in our review. The results of our review demonstrated that visceral pain behaviors were significantly alleviated in response to acupuncture treatment in groups treated with this intervention compared to in sham acupuncture or no-treatment groups. Changes in the concentrations of β-endorphin, epinephrine, cortisol, and prostaglandin E2 in plasma, the levels of c-Fos, substance P, corticotropin-releasing hormone, P2X3, acetylcholinesterase (AchE), N-methyl-D-aspartate (NMDA) receptors, and serotonin in the gut/spinal cord, and the neuronal activity of the thalamus were associated with acupuncture treatment in visceral pain.

Conclusions

Acupuncture reduced visceral pain behavior and induced significant changes in neuronal activity as well as in the levels of pain/inflammation-related cytokines and neurotransmitters in the brain-gut axis. Further researches on the thalamus and on a standard animal model are warranted to improve our knowledge on the mechanism of acupuncture that facilitates visceral pain modulation.

Acupuncture therapy for fibromyalgia: a systematic review and meta-analysis of randomized controlled trials

Purpose

Fibromyalgia (FM) can cause chronic widespread pain and seriously affect the quality of patient lives. Acupuncture therapy is widely used for pain management. However, the effect of acupuncture on FM is still uncertain. The aim of this review was to determine the effect and safety of acupuncture therapy on the pain intensity and quality of life in patients with FM.

Materials and methods

We searched PubMed, the Cochrane Library, Embase, the China National Knowledge Infrastructure, the Chinese Science and Technology Periodical Database, and the Chinese Biomedical Literature Database to collect randomized controlled trials (RCTs) of acupuncture for FM published before May 2018. A meta-analysis was performed according to the Cochrane systematic review method by using RevMan 5.3 software, and GRADE was used to evaluate the quality of the evidence.

Results

We identified 12 RCTs that compared acupuncture therapy to sham acupuncture or conventional medication. Meta-analysis showed that acupuncture was significantly better than sham acupuncture for relieving pain (MD =−1.04, 95% CI [−1.70, –0.38], P=0.002, I²=78%) and improving the quality of life (MD =−13.39, 95% CI [−21.69, –5.10], P=0.002, I²=82%), with low- to moderate-quality evidence in the short term. At follow-up in the long term, the effect of acupuncture was also superior to that of sham acupuncture. No serious adverse events were found during acupuncture.

Conclusion

Acupuncture therapy is an effective and safe treatment for patients with FM, and this treatment can be recommended for the management of FM.
