Effect of Acupuncture on Sensorimotor Function and Mobility in Patients with Multiple Sclerosis: A Pilot Study

Introduction: Multiple sclerosis (MS) is a progressive disease of the central nervous system that can result in highly variable effects on mobility and sensorimotor function. Persons with MS (pwMS) often use complementary and alternative approaches, such as acupuncture, to address these symptoms. However, studies of acupuncture on these symptoms have been hindered by methodologic flaws, which have limited the ability to draw conclusions about its efficacy. The purpose of this study was to examine the feasibility of an acupuncture intervention on a wide range of sensorimotor and mobility measurements in pwMS. Methods: Using a randomized crossover design, subjects experienced acupuncture or a no treatment control condition twice weekly for 4 weeks, followed by a 4-week washout period, and then crossed over to the other condition for 4 weeks. Strength, sensation, spasticity, gait, and balance were measured for all subjects, both before and after each condition. Results: Seven of the 12 subjects who started the program completed all phases. No subjects experienced adverse effects. No statistically significant changes were observed in the gait or balance measures. Small statistically significant changes were observed in upper extremity strength. Sensation and spasticity were unaffected. Discussion: The variability of MS suggests that a wide array of testing procedures be utilized, however, this may have led to difficulty with completing all phases of the study. Acupuncture did not result in changes in mobility in pwMS. Some improvements in upper extremity strength were observed. It is unclear whether these changes represent the effect of acupuncture or the inherent variability of MS.

Acupuncture for Managing Cancer-Related Fatigue in Breast Cancer Patients: A Systematic Review and Meta-Analysis

Breast cancer (BC) is the most common cancer in women and is a serious threat to women's health. Cancer-related fatigue (CRF) is a distressing symptom in BC patients during and after chemotherapy or radiation therapy that severely affects quality of life (QoL). AT is widely used for fatigue management. However, the effect of AT on CRF is still uncertain. This study aimed to evaluate the efficacy and safety of AT in the management of CRF in patients with BC. Eleven databases were searched through June 2022. Two researchers independently performed the database search, study selection, data extraction, and risk of bias assessment. Study selection was performed based on predefined Participants, Intervention, Comparators, Outcomes, Study design (PICOS) criteria, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed when reporting the results. A meta-analysis was performed according to the Cochrane systematic review method using RevMan 5.3. A total of 12 studies including a total of 1084 participants were included. The results showed that AT had a beneficial effect compared with sham AT (n = 256, SMD = -0.26, 95% CI [-0.51, -0.01], p = 0.04, I² = 0%) and a long-term effect on fatigue score (n = 209, MD = -0.32, 95% CI [-0.59, -0.04], p = 0.02, I² = 0%). Meta-analysis showed that AT had a beneficial effect compared with usual care (UC) on fatigue scores (n = 238, SMD = -0.39, 95% CI [-0.66 to -0.12], p = 0.005, I² = 0%). Of the 12 articles, 3 articles were judged as having a low risk of bias in all domains and hence were of high quality. No serious adverse effects were identified. AT is an effective and safe treatment for CRF, and AT is more effective than sham AT or UC or wait-list control (WLC). Nevertheless, the methodological quality of most of these studies was low, and the included studies/sample sizes were small, so the ability to derive decisive implications was limited. Further research is needed to confirm these findings.

Effect of Somatosensory Interaction Transcutaneous Electrical Acupoint Stimulation on Cancer-related Fatigue and Immunity: A Randomized Controlled Trial

BACKGROUND

This study was intended to evaluate the clinical effect of somatosensory interaction transcutaneous electrical acupoint stimulation (SI-TEAS) on cancer-related fatigue (CRF) and its safety.

METHODS

The study protocol had been registered in China Clinical Trial Registration Center with registration number: ChiCTR2100045655. CRF patients were equally divided into SI-TEAS Group, Acupressure Group and Sham Acupressure Group to receive SI-TEAS, acupressure and sham acupressure treatments 5 times a week. The fatigue levels of patients in the 3 groups were measured by the Piper Fatigue Scale during the baseline period and after 4 and 8 weeks (of treatment). The cell immunity of these patients was determined by detecting the T-lymphocyte subsets and NK cells.

RESULT

Of the 300 participants, 279 have gone through the independent rehabilitation intervention study, including 94 in the SI-TEAS Group, 92 in the Acupressure Group, and 93 in the Sham Acupressure Group. Intergroup comparisons of fatigue degree and cell immunity, namely SI-TEAS Group versus Acupressure Group, Acupressure Group versus Sham Acupressure Group, and SI-TEAS Group versus Sham Acupressure Group, showed that group changes observed during the baseline period and different time points after Week 4 and 8 were statistically different (P<0.05). The SI-TEAS Group had the sharpest decreases in the behavioral, sensory, emotional and cognitive dimensions of fatigue, and the total score, followed by the Acupressure Group, while the Sham Acupressure Group did not show significant changes; the SI-TEAS Group experienced the sharpest increases in the absolute counts of CD3+ T cells, CD4+ T cells, CD8+ T cells, CD4+/CD8+ T cells, and NK cells, followed by the Acupressure Group, while the Sham Acupressure Group did not show significant changes.

CONCLUSION

SI-TEAS could significantly relieve the fatigue of CRF patients and improve their cell immunity, which maybe a useful and effective option for reducing CRF in clinical practice.

Incorporating Acupuncture Into American Healthcare: Initiating a Discussion on Implementation Science, the Status of the Field, and Stakeholder Considerations

INTRODUCTION

The field of implementation science is the study of methods that promote the uptake of evidence-based interventions into healthcare policy and practice. While acupuncture has gained significant traction in the American healthcare landscape, its journey has been somewhat haphazard and non-linear.

METHODS

In June 2019, a group of thirty diverse stakeholders was convened by the Society for Acupuncture Research with the support of a Patient Centered Outcomes Research Institute, Eugene Washington Engagement Award. This group of stakeholders represented a diverse mix of patients, providers, academicians, researchers, funders, allied health professionals, insurers, association leaders, certification experts, and military program developers. The collective engaged in discussion that explored acupuncture's status in healthcare, including reflections on its safety, effectiveness, best practices, and the actual implementation of acupuncture as seen from diverse stakeholder viewpoints.

OBJECTIVES

A primary goal was to consider how to utilize knowledge from the field of implementation science more systematically and intentionally to disseminate information about acupuncture and its research base, through application of methods known to implementation science. The group also considered novel challenges that acupuncture may present to known implementation processes.

FINDINGS

This article summarizes the initial findings of this in-person meeting of stakeholders and the ongoing discussion among the subject matter experts who authored this report. The goal of this report is to catalyze greater conversation about how the field of implementation science might intersect with practice, access, research, and policymaking pertaining to acupuncture. Core concepts of implementation science and its relationship to acupuncture are introduced, and the case for acupuncture as an Evidence Based Practice (EBP) is established. The status of the field and current environment of acupuncture is examined, and the perspectives of four stakeholder groups--patients, two types of professional practitioners, and researchers--are explored in more detail.

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.

The Role of Research in Guiding Treatment for Women's Health: A Qualitative Study of Traditional Chinese Medicine Acupuncturists

Background: Surveys of acupuncture practitioners worldwide have shown an increase in the use of acupuncture to treat women’s health conditions over the last ten years. Published studies have explored the effectiveness of acupuncture for various conditions such as period pain, fertility, and labor induction. However, it is unclear what role, if any, peer-reviewed research plays in guiding practice. Methods: Acupuncturists with a significant women’s health caseload were interviewed online in three small groups to explore factors that contribute to acupuncturists’ clinical decision made around treatment approaches and research. Results: Eleven practitioners participated in the focus groups. The overarching theme that emerged was one of ‘Not mainstream but a stream.’ This captured two themes relating to acupuncture as a distinct practice: ‘working with what you’ve got’ as well as ‘finding the right lens’, illustrating practitioners’ perception of research needing to be more relevant to clinical practice. Conclusions: Acupuncture practitioners treating women’s health conditions reported a disconnect between their clinical practice and the design of clinical trials, predominantly due to what they perceived as a lack of individualization of treatment. Case histories were popular as a learning tool and could be used to support increasing research literacy.

Clinical effect of catgut implantation at acupoints for the treatment of simple obesity: A multicentre randomized controlled trial

BACKGROUND

Catgut implantation at acupoints (CIA) is a subtype of acupuncture that has been widely used to treat simple obesity, but evidence for its effectiveness remains scarce. The aim of this study is to evaluate the efficacy and safety of treating simple obesity with CIA.

OBJECTIVE

This clinical trial aims to evaluate the effectiveness and safety of CIA used for treatment of simple obesity.

METHODS

This is a multicentre, randomized, parallel, sham-controlled clinical trial. A total of 216 patients with simple obesity will be recruited. They will be randomly assigned in a 1:1 ratio to either the CIA group or the sham control group. All treatments will be given once every 2 weeks. The primary outcome measure is the rate of waistline reduction. Secondary outcome measures are the rates of reduction of body measurements, including weight, body mass index (BMI), hipline, waist-hip-ratio (WHR) and body fat percentage (BFP), the changes in scores on scales, including the Impact of Weight on Quality of Life Questionnaire (IWQOL-Lite), Short Form 36 (SF-36), the Hospital Anxiety and Depression Scale (HAD) and the Self-Esteem Scale (SES), Outcomes will be evaluated at baseline and at weeks 4, 8, 12, 16, 28, and 40, respectively. All adverse events that occur during this study will be recorded. If any participant withdraws from the trial, an intention-to-treat analysis (ITT) will be performed.

CONCLUSION

This is a randomized, sham-controlled trial of CIA treatment for simple obesity. The results of this trial will provide more evidence on whether CIA is efficacious and safe for treating obesity.

Electroacupuncture trigeminal nerve stimulation plus body acupuncture for chemotherapy-induced cognitive impairment in breast cancer patients: An assessor-participant blinded, randomized controlled trial

Chemotherapy causes various side effects, including cognitive impairment, known as 'chemobrain'. In this study, we determined whether a novel acupuncture mode called electroacupuncture trigeminal nerve stimulation plus body acupuncture (EA/TNS + BA) could produce better outcomes than minimum acupuncture stimulation (MAS) as controls in treating chemobrain and other symptoms in breast cancer patients. In this assessor- and participant-blinded, randomized controlled trial, 93 breast cancer patients under or post chemotherapy were randomly assigned to EA/TNS + BA (n = 46) and MAS (n = 47) for 2 sessions per week over 8 weeks. The Montreal Cognitive Assessment (MoCA) served as the primary outcome. Digit span test was the secondary outcomes for attentional function and working memory. The quality of life and multiple functional assessments were also evaluated. EA/TNS + BA treated group had much better performance than MAS-treated group on reverse digit span test at Week 2 and Week 8, with medium effect sizes of 0.53 and 0.48, respectively, although no significant differences were observed in MoCA score and prevalence of chemobrain between the two groups. EA/TNS + BA also markedly reduced incidences of diarrhoea, poor appetite, headache, anxiety, and irritation, and improved social/family and emotional wellbeing compared to MAS. These results suggest that EA/TNS + BA may have particular benefits in reducing chemotherapy-induced working memory impairment and the incidence of certain digestive, neurological, and distress-related symptoms. It could serve as an effective intervention for breast cancer patients under and post chemotherapy (trial registration: https://www.clinicaltrials.gov: NCT02457039).

Effectiveness of acupuncture vs. core stability training in balance and functional capacity of women with fibromyalgia: a randomized controlled trial

OBJECTIVE

This study investigated the effectiveness of a core stability training physiotherapy programme vs. acupuncture for the management of balance and functional capacity impairments of women with Fibromyalgia.

DESIGN

Single-blind randomized controlled trial.

SETTING

Outpatients setting.

SUBJECTS

Women with Fibromyalgia and balance impairment.

INTERVENTIONS

Participants were randomized to a core stability physiotherapy programme group (n = 45), acupuncture treatment group (n = 45) and control group (n = 45) for 13 weeks.

MAIN MEASURES

Measures were taken at baseline (week 0), postintervention (week 6) and follow-up (week 13). The primary outcome measures were static balance (posturography) and dynamic balance and functional mobility (Berg Balance Scale, timed up and go test and 10-m walk). The secondary outcome measure was functional capacity (Fibromyalgia Health Assessment Questionnaire and the physical function item from the Spanish Fibromyalgia Impact Questionnaire).

RESULTS

In all, 103 participants completed the study. The results showed statistically significant improvements in the acupuncture and physiotherapy groups vs. the control group at week 6 regarding Berg Balance Scale (P = 0.00, both groups), timed up and go test (P = 0.00 and P = 0.01, respectively) and 10-m walk test at comfortable speed (P = 0.02 and P = 0.03, respectively). The 10-m walk test at maximum speed showed significance when comparing the physiotherapy and control group (P = 0.03). However, no significant differences were found between the physiotherapy and the acupuncture groups. In relation to functional capacity, the improvements achieved after the treatments were not statistically significant.

CONCLUSION

Core stability-based physiotherapy and acupuncture improve dynamic balance and postural control in women with Fibromyalgia.

Assessor- and participant-blinded, randomized controlled trial of dense cranial electroacupuncture stimulation plus body acupuncture for neuropsychiatric sequelae of stroke

AIM

Acupuncture has benefits in the rehabilitation of neuropsychiatric sequelae of stroke. This study was aimed to evaluate the effectiveness of dense cranial electroacupuncture stimulation plus body acupuncture (DCEAS+BA) in treating poststroke depression (PSD), functional disability, and cognitive deterioration.

METHODS

In this assessor- and participant-blinded, randomized controlled trial, 91 stroke patients who initially had PSD were randomly assigned to either DCEAS+BA (n = 45) or minimum acupuncture stimulation as controls (n = 46) for three sessions per week over 8 consecutive weeks. The primary outcome was baseline-to-end-point change in score of the 17-item Hamilton Depression Rating Scale. Secondary outcomes included the Montgomery-Åsberg Depression Rating Scale for depressive symptoms, the Barthel Index for functional disability, and the Montreal Cognitive Assessment for cognitive function.

RESULTS

DCEAS+BA-treated patients showed strikingly greater end-point reduction than MAS-treated patients in scores of the three symptom domains. The clinical response rate, defined as an at least 50% baseline-to-end-point reduction in 17-item Hamilton Depression Rating Scale score, was markedly higher in the DCEAS+BA-treated group than that of controls (40.0% vs 17.4%, P = 0.031). Incidence of adverse events was not different in the two groups. Subgroup analysis revealed that DCEAS+BA with electrical stimulation on forehead acupoints was more apparent in reducing Barthel-Index-measured disability than that without electrical stimulation.

CONCLUSION

DCEAS+BA, particularly with electrical stimulation on forehead acupoints, reduces PSD, functional disability, and cognitive deterioration of stroke patients. It can serve as an effective rehabilitation therapy for neuropsychiatric sequelae of stroke.

International ResearchKit App for Women with Menstrual Pain: Development, Access, and Engagement

BACKGROUND

Primary dysmenorrhea is a common condition in women of reproductive age. A previous app-based study undertaken by our group demonstrated that a smartphone app supporting self-acupressure introduced by a health care professional can reduce menstrual pain.

OBJECTIVE

This study aims to evaluate whether a specific smartphone app is effective in reducing menstrual pain in 18- to 34-year-old women with primary dysmenorrhea in a self-care setting. One group of women has access to the full-featured study app and will be compared with 2 control groups who have access to fewer app features. Here, we report the trial design, app development, user access, and engagement.

METHODS

On the basis of the practical implications of the previous app-based study, we revised and reengineered the study app and included the ResearchKit (Apple Inc) framework. Behavior change techniques (BCTs) were implemented in the app and validated by expert ratings. User access was estimated by assessing recruitment progress over time. User evolution and baseline survey respondent rate were assessed to evaluate user engagement.

RESULTS

The development of the study app for a 3-armed randomized controlled trial required a multidisciplinary team. The app is accessible for the target population free of charge via the Apple App Store. In Germany, within 9 months, the app was downloaded 1458 times and 328 study participants were recruited using it without external advertising. A total of 98.27% (5157/5248) of the app-based baseline questions were answered. The correct classification of BCTs used in the app required psychological expertise.

CONCLUSIONS

Conducting an innovative app study requires multidisciplinary effort. Easy access and engagement with such an app can be achieved by recruitment via the App Store. Future research is needed to investigate the determinants of user engagement, optimal BCT application, and potential clinical and self-care scenarios for app use.

The Effects of Acupuncture on Cancer-Related Fatigue: Updated Systematic Review and Meta-Analysis

BACKGROUND

Several studies have identified fatigue as one of the major symptoms experienced during and after cancer treatment. However, there are limited options to manage cancer related fatigue (CRF) with pharmacological interventions. Several acupuncture studies suggested that acupuncture has a positive impact on CRF. This review aims to assess the evidence of acupuncture for the treatment of CRF.

METHOD

Electronic database searches were conducted on 4 English databases (Medline, PubMed, Embase, and ScienceDirect). Search keywords were; "acupuncture" and "cancer," or "cancer related fatigue." Studies published as full text randomized controlled trials (RCTs) in English were included. Estimates of change in fatigue cores were pooled using a random effects meta-analysis where randomized comparisons were available for true acupuncture versus sham acupuncture and true acupuncture versus usual care. The quality of original papers were assessed using the Cochrane Collaboration's tool for assessing risk of bias (ROB).

RESULTS

Nine RCTs were selected for review with a total of 809 participants and a range of 13 to 302 participants within the studies. Six RCTs reported significant improvement of CRF for the acupuncture intervention compared to the control groups. Pooled estimates suggest Brief Fatigue Inventory scores are 0.93 points lower 95% CI (-1.65, -0.20) in true acupuncture versus sham acupuncture and 2.12 points lower 95% C (-3.21, -1.04) in true acupuncture versus usual care. Six studies had low risk of bias (ROB) and 3 studies had a moderate ROB predominantly in blinding of participants, blinding of assessors and incomplete data outcomes. Among the 9 RCTs, 2 studies have reported the occurrence of minor adverse effects (spot bleeding and bruising) related to acupuncture treatment. No serious adverse reactions related to acupuncture were reported.

CONCLUSION

The current literature review suggests that acupuncture has therapeutic potential in management of CRF for cancer survivors. Promotion of acupuncture in cancer care to manage CRF may improve the quality of life of cancer survivors.

Electroacupuncture plus on-demand gastrocaine for refractory functional dyspepsia: Pragmatic randomized trial

BACKGROUND AND AIM

Treatment options for functional dyspepsia (FD) refractory to pharmacological treatments are limited but the effectiveness of electroacupuncture (EA) is uncertain. We assessed the effectiveness of EA combined with on-demand gastrocaine.

METHODS

We conducted a single-center, assessor-blind, randomized parallel-group 2-arm trial on Helicobacter pylori negative FD patients of the postprandial distress syndrome subtype refractory to proton pump inhibitor, prokinetics, or H₂ antagonists. Enrolled participants were block randomized in a 1:1 ratio, with concealed random sequence. The treatment and control groups both received on-demand gastrocaine for 12 weeks, but only those in treatment group were offered 20 sessions of EA over 10 weeks. The primary endpoint was the between-group difference in proportion of patients achieving adequate relief of symptoms at week 12.

RESULTS

Of 132 participants randomly assigned to EA plus on-demand gastrocaine (n = 66) or on-demand gastrocaine alone (n = 66), 125 (94.7%) completed all follow-up at 12 weeks. The EA group had a compliance rate 97.7%. They had a significantly higher likelihood in achieving adequate symptom relief at 12 weeks, with a clinically relevant number needed to treat (NNT) value of 2.36 (95% CI: 1.74, 3.64). Among secondary outcomes, statistically and clinically significant improvements were observed among global symptom (NNT = 3.85 [95% CI: 2.63, 7.69]); postprandial fullness and early satiation (NNT = 5.00 [95% CI: 2.86, 25.00]); as well as epigastric pain, epigastric burning, and postprandial nausea (NNT = 4.17 [95% CI: 2.56, 11.11]). Adverse events were minimal and nonsignificant.

CONCLUSION

For refractory FD, EA provides significant, clinically relevant symptom relief when added to on-demand gastrocaine (ChiCTR-IPC-15007109).

Research-related attitudes among Chinese medicine students at a Canadian college: a mixed-methods study

BACKGROUND

Previous studies have suggested that American Chinese medicine students' research interest declines as their training progresses. Many students further express low confidence in the congruence ('model validity') of bioscientific research methods in relation to the Chinese medicine paradigm. However, prior research has not assessed the impacts of research-related coursework on student perspectives in this regard.

METHODS

First-, second- and third-year Chinese medicine students were surveyed regarding their research-related views. Final year students were re-surveyed after completing the research course. Qualitative analyses of the participating students' coursework were also undertaken.

RESULTS

Over 80% of all participants showed high research interest and engagement, and viewed research as both relevant to clinical practice and important for the profession's socioeconomic legitimation. Male students were significantly more likely to view scientific evidence as improving the quality of Chinese medicine care (p = 0.021). A view that conventional research methods have low model validity for Chinese medicine interventions was higher among third year students than those in their first or second years of study (p = 0.001). Research coursework appeared to increase self-assessed research interest and skill. Concern regarding model validity was strongly evident in student coursework.

CONCLUSION

Research-related curricular interventions in the Chinese medicine field should directly address model validity, as it is of significant interest to a majority of students.

Acupuncture for cancer pain: protocol for a pilot pragmatic randomised controlled trial

INTRODUCTION

Although acupuncture has been recommended for alleviating cancer pain by clinical guidelines, the level of the supporting evidence needs to be improved. A pragmatic randomised controlled trial (pRCT) in a hospital setting would provide real-world assessments of the overall clinical effects of acupuncture. This pilot trial aims to explore the feasibility and provide data for sample size calculations for a pRCT evaluating the effectiveness of acupuncture as an adjunctive therapy to routine medical care for cancer pain.

METHODS AND ANALYSIS

Thirty patients with cancer admitted to the oncology department with moderate or severe pain will be recruited. Participants will be randomised at a ratio of 1:1 to the adjunctive acupuncture group or a control group which receives routine pain management without acupuncture. The standardised section of the acupuncture protocol will be developed based on the results of reviews of the literature, recommendations in clinical guidelines and interviews with clinical experts. The acupuncturist will be allowed to tailor the protocol according to the individual situation of each participant. Primary outcomes relevant to the feasibility of conducting a fully powered trial include: numbers and proportions of participants recruited, screened, consented and randomised; numbers and reasons for withdrawals and dropouts; numbers and types of adverse events; feasibility of implementing the trial procedures; evaluation of the comprehensiveness and ease-of-use of the case report form. Secondary outcomes are clinical measurements of the effectiveness of the treatment that are intended for use in the full-scale trial. Analysis of feasibility will be descriptive and pain intensity measures will be analysed using mixed-effects regression.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Institutional Ethics Committee of Guangdong Provincial Hospital of Chinese Medicine (approval no: Z2017-184-01) and RMIT University Human Research Ethics Committee (reference no: 21361). Results will be disseminated in a peer-reviewed journal, and trial participants will be informed via email and/or phone calls.

A Guideline for Randomized Controlled Trials of Acupuncture

Guidelines for clinical trials of acupuncture are scarce, particularly in their guidance on choosing an adequate control in an acupuncture trial. This guideline was developed to address the research methodology for clinical research in acupuncture which contains the essential elements to be considered in the design, preparation and reporting of an acupuncture RCT. Particularly, investigators focused on the control design because of the unique feature of acupuncture. As one size does not fit all, one single design cannot answer all research questions. Therefore, we recommend that the clinical questions be answered in different stages of trials by choosing the appropriate control or comparator. This concept is adapted from classical drug trials developed by the Food and Drug Administration (FDA) of USA in which trials are staged in four phages in order to address different research questions. From the points listed above, this guideline offers the specific recommendations in an acupuncture RCT.

Efficacy of acupressure to prevent adverse reactions to anti-tuberculosis drugs: Randomized controlled trials

AIM

To determine whether acupressure can prevent or relieve the adverse drug reactions (ADRs) of anti-tuberculosis drugs.

BACKGROUND

People receiving drug treatment for TB often experience ADRs that may cause them to stop taking their medication. Acupressure is a form of traditional Chinese medicine that can be applied to alleviate or prevent disease symptoms.

DESIGN

A double-blinded, repeated-measures clinical trial in hospitals in Taiwan was carried out from April 2015 - May 2017.

METHODS

Convenience sampling was used to select 32 people (15 for the experimental group and 17 for the control group) aged >20 years who were taking anti-tuberculosis drugs. The people were randomized to receive 4-week of true acupressure and 4-weeks of sham acupressure. Acupressure therapy was given by a researcher in all cases. Both groups received treatment once per day on weekdays, with 15 min for each acupressure session. Outcomes (gastrointestinal irritation and adverse skin reactions) were assessed according to the people feedback and the physicians' recordings during the treatment course, and during monthly follow-up visits for 6 months thereafter.

RESULTS

Both groups typically experienced gastrointestinal irritation and adverse skin reactions within 2 months of beginning anti-tuberculosis drug treatment. The 4-weeks intervention involving relevant acupressure points successfully relieved both types of side effects in both immediate and delayed manner.

CONCLUSIONS

When correctly implemented, acupressure can prevent and relieve the ADRs of anti-tuberculosis drugs, and motivate people to complete their treatment course.

Acupuncture or metformin to improve insulin resistance in women with polycystic ovary syndrome: study protocol of a combined multinational cross sectional case-control study and a randomised controlled trial

INTRODUCTION

Polycystic ovary syndrome (PCOS) is linked to hyperinsulinemia and insulin resistance with dysfunctional glucose metabolism. Pilot studies suggests that acupuncture treatment with combined manual and low-frequency electrical stimulation (electroacupuncture (EA)) of the needles decrease circulating glycated haemoglobulin (HbA1c) and homeostatic model assessment-insulin resistance. Therefore, we here aim to investigate if acupuncture treatment or metformin together with lifestyle or lifestyle management alone improves insulin sensitivity and related symptoms in overweight/obese women with PCOS.

METHODS AND ANALYSIS

This is a two-centre multinational (Sweden and China), cross-sectional case-control study combined with an open-labelled randomised controlled trial (RCT). Participants are randomised to one of three groups: (1) EA 2-3 times/week during 4 months+lifestyle management; (2) metformin, 500 mg, three/day during 4 months+lifestyle management; or (3) lifestyle management alone. The primary outcome measure in the RCT is changes in HbA1C. A total of 123 obese overweight women with PCOS will be enrolled and randomised into one of the three groups with a target power of at least 80% and 5% significance level based on two-sided tests.

ETHICS AND DISSEMINATION

The study has been approved by the Regional Ethical Review Board of Stockholm and of Peking University Third Hospital, China. Primary outcome data of the RCT will be published in a relevant journal together with supporting secondary outcome measurements. Further, outcome measurements will be published in separate papers as well as case-control data.

EXPECTED RESULTS

We anticipate that EA and metformin, both with lifestyle management, are equally effective and superior to lifestyle management alone for improvement of glycaemic control.

A Feasibility Study to Examine the Role of Acupuncture to Reduce Symptoms of Lymphoedema after Breast Cancer: A Randomised Controlled Trial

Objective

To determine the feasibility, acceptability and safety of using acupuncture to treat arm lymphoedema in women following treatment for breast cancer.

Methods

We conducted a randomised controlled trial of acupuncture compared with treatment as usual. Twenty women with stable unilateral intransient lymphoedema present for at least 6 months were recruited from Sydney, Australia. The women received 12 acupuncture treatments administered to body and arm points on the non-lymphoedematous limb over 8 weeks, twice weekly for 4 weeks then once weekly for 4 weeks. Outcome measures included an assessment of interest to participate in the trial, identification of successful recruitment strategies, the appropriateness of eligibility criteria and compliance with treatment attendance. Clinical outcomes were assessed at baseline and 8 weeks and included extracellular fluid, lymphoedema symptoms, well-being and safety.

Results

Acupuncture was an acceptable intervention in women with upper limb lymphoedema. Compliance with the treatment protocol was high, with nine women completing all 12 treatments. Outcome forms were completed by 17 women at 8 weeks. No major adverse occurrences, as defined by the study protocol, were reported from the acupuncture group although one woman found the needling uncomfortable, and no study participant experienced an increase in swelling of >10%. There was no change in extracellular fluid or any patient-reported outcome measurement.

Conclusions

Lymphoedema is a persistent symptom experienced by women recovering from breast cancer. Our study suggests that acupuncture may stabilise symptoms and no major safety concerns were identified, so further research is needed.

Current evidence of acupuncture for symptoms related to breast cancer survivors: A PRISMA-compliant systematic review of clinical studies in Korea

BACKGROUND

Breast cancer survivors experience various symptoms associated with their cancer interventions, and the benefits of acupuncture for these symptoms have been evaluated in clinical trials worldwide. The purpose of this review was to discuss the current status of clinical research regarding the use of acupuncture as a part of traditional Korean medicine (KM) for various symptoms associated with breast cancer therapies.

METHODS

We conducted a systematic review of the literature regarding the use of acupuncture as a part of traditional KM to treat symptoms associated with breast cancer therapies. The following databases were searched for content up to February 2017: MEDLINE, EMBASE, the Cochrane library, 4 Korean databases, and conference proceedings from major Korean medical societies.

RESULTS

Among the 1228 identified articles, 8 observational studies (3 case series and 5 case reports), and 1 randomized controlled trial (RCT) were included in this review. Among these studies, 3 investigated lymphedema, 2 investigated chemotherapy-induced peripheral neuropathy, 1 investigated hot flushes, 1 investigated constipation, and 2 investigated miscellaneous symptoms in breast cancer survivors; all studies concluded that acupuncture can alleviate the symptom in question. However, we identified only 1 relevant RCT, and the included studies had limitations in terms of reporting quality.

CONCLUSION

There is a lack of conclusive evidence regarding the benefits of acupuncture for the treatment of breast cancer survivors in Korea. More rigorous RCTs are necessary in the future to establish stronger clinical evidence regarding the use of acupuncture to better reflect the clinical context of Korea.

Electroacupuncture plus standard of care for managing refractory functional dyspepsia: protocol of a pragmatic trial with economic evaluation

INTRODUCTION

This trial proposes to compare the effectiveness and cost-effectiveness of electroacupuncture (EA) plus on-demand gastrocaine with waiting list for EA plus on-demand gastrocaine in providing symptom relief and quality-of-life improvement among patients with functional dyspepsia (FD).

METHODS AND ANALYSIS

This is a single-centre, pragmatic, randomised parallel-group, superiority trial comparing the outcomes of (1) EA plus on-demand gastrocaine group and (2) waiting list to EA plus on-demand gastrocaine group. 132 (66/arm) endoscopically confirmed, Helicobacter pylori-negative patients with FD will be recruited. Enrolled patients will respectively be receiving (1) 20 sessions of EA over 10 weeks plus on-demand gastrocaine; or (2) on-demand gastrocaine and being nominated on to a waiting list for EA, which entitles them 20 sessions of EA over 10 weeks after 12 weeks of waiting. The primary outcome will be the between-group difference in proportion of patients achieving adequate relief of symptoms over 12 weeks. The secondary outcomes will include patient-reported change in global symptoms and individual symptoms, Nepean Dyspepsia Index, Nutrient Drink Test, 9-item Patient Health Questionnaire (PHQ9), and 7-item Generalised Anxiety Disorder Scale (GAD7). Adverse events will be assessed formally. Results on direct medical costs and on the EuroQol (EQ-5D) questionnaire will also be used to assess cost-effectiveness. Analysis will follow the intention-to-treat principle using appropriate univariate and multivariate methods. A mixed model analysis taking into account missing data of these outcomes will be performed. Cost-effectiveness analysis will be performed using established approach.

ETHICS AND DISSEMINATION

The study is supported by the Health and Medical Research Fund, Government of the Hong Kong Special Administrative Region of China. It has been approved by the Joint Chinese University of Hong Kong - New Territories East Cluster Clinical Research Ethics Committee. Results will be published in peer-reviewed journals and be disseminated in international conference.

Acupuncture for Symptom Relief in Palliative Care-Study Protocol and Semistandardized Treatment Schemes

The use of complementary and alternative medicine methods such as acupuncture in palliative care has increased over the past years. Well-planned trials are warranted to show its effectiveness in relieving distressing symptoms. The development of treatment schemes to be used in the trial for both acupuncture and medical symptom control is challenging, as both acupuncture and palliative care are highly individualized. Thus, standardized care plans of a randomized controlled trial will have difficulties in producing treatment results that compare to the clinical practice. As an alternative, treatment protocols for both acupuncture and medical symptom control of dyspnea, pruritus, hypersalivation, depression, anxiety, and xerostomia were designed with the input of experts. They are designed to provide sufficient symptom control and comparability for a three-arm, randomized controlled trial. Medical symptom control will be provided to all groups. The two control groups will be medical treatment and sham-laser acupuncture.

Electroacupuncture and splinting versus splinting alone to treat carpal tunnel syndrome: a randomized controlled trial

BACKGROUND

The effectiveness of acupuncture for managing carpal tunnel syndrome is uncertain, particularly in patients already receiving conventional treatments (e.g., splinting). We aimed to assess the effects of electroacupuncture combined with splinting.

METHODS

We conducted a randomized parallel-group assessor-blinded 2-arm trial on patients with clinically diagnosed primary carpal tunnel syndrome. The treatment group was offered 13 sessions of electroacupuncture over 17 weeks. The treatment and control groups both received continuous nocturnal wrist splinting.

RESULTS

Of 181 participants randomly assigned to electroacupuncture combined with splinting (n = 90) or splinting alone (n = 91), 174 (96.1%) completed all follow-up. The electroacupuncture group showed greater improvements at 17 weeks in symptoms (primary outcome of Symptom Severity Scale score mean difference [MD] -0.20, 95% confidence interval [CI] -0.36 to -0.03), disability (Disability of Arm, Shoulder and Hand Questionnaire score MD -6.72, 95% CI -10.9 to -2.57), function (Functional Status Scale score MD -0.22, 95% CI -0.38 to -0.05), dexterity (time to complete blinded pick-up test MD -6.13 seconds, 95% CI -10.6 to -1.63) and maximal tip pinch strength (MD 1.17 lb, 95% CI 0.48 to 1.86). Differences between groups were small and clinically unimportant for reduction in pain (numerical rating scale -0.70, 95% CI -1.34 to -0.06), and not significant for sensation (first finger monofilament test -0.08 mm, 95% CI -0.22 to 0.06).

INTERPRETATION

For patients with primary carpal tunnel syndrome, chronic mild to moderate symptoms and no indication for surgery, electroacupuncture produces small changes in symptoms, disability, function, dexterity and pinch strength when added to nocturnal splinting.

Survey of Chinese Medicine Students to Determine Research and Evidence-Based Medicine Perspectives at Pacific College of Oriental Medicine

CONTEXT

Research literacy and the practice of evidence-based medicine (EBM) are important initiatives in complementary and alternative medicine (CAM), which requires cultural change within educational institutions for successful implementation.

OBJECTIVE

To determine the self-assessed research and EBM perspectives of Chinese medicine Masters degree students at Pacific College of Oriental Medicine, New York campus (PCOM-NY).

DESIGN AND METHODS

A survey with 17 close-ended questions and one open-ended question was administered through Survey Monkey to students at PCOM-NY.

RESULTS

The survey was sent to 420 Masters students and 176 (41.9%) responded. Students in all four years of the Masters degree indicated a generally high degree of interest in, and support for the value of research. However, increasing years (one to four years) in the program was associated with lower interest in post-graduation research participation and entering the doctoral program, and the fourth year students reported low levels of interest in having greater research content and training in their Masters degree programs. Students who responded to the open-ended question (23% of respondents) expressed enthusiasm for research and concerns about the relevance of research in Chinese medicine.

CONCLUSIONS

Consistent with findings in similar studies at CAM colleges, interest in research, and EBM of the PCOM-NY Masters students appeared to decline with increasing years in the program. Concerns around paradigm and epistemological issues associated with research and EBM among Chinese medicine students and practitioners warrants further investigation, and may be an important challenge for integrative medicine.

Adjunctive acupuncture for pain and symptom management in the inpatient setting: protocol for a pilot hybrid effectiveness-implementation study

BACKGROUND

Effective pain management among hospitalized patients is an important aspect of providing quality care and achieving optimal clinical outcomes and patient satisfaction. Common pharmacologic approaches for pain, though effective, have serious side effects and are not appropriate for all inpatients. Findings from randomized controlled trials (RCTs) support the efficacy of acupuncture for many symptoms relevant to inpatients including postoperative pain, cancer-related pain, nausea and vomiting, and withdrawal from narcotic use. However, the extent to which findings from RCTs translate to real-world implementation of acupuncture in typical hospital settings is unknown.

METHODS/DESIGN

In partnership with the launch of a clinical program offering acupuncture services to inpatients at the University of California San Francisco's Mount Zion Hospital, we are conducting a pilot study using a hybrid effectiveness-implementation design to: (1) assess the effectiveness of acupuncture to manage pain and other symptoms and improve patient satisfaction; and (2) evaluate the barriers and facilitators to implementing an on-going acupuncture service for inpatients. During a two-month pre-randomization phase, we evaluated and adapted clinical scheduling and treatment protocols with acupuncturists and hospital providers and pretested study procedures including enrollment, consent, and data collection. During a six-month randomization phase, we used a two-tiered consent process in which inpatients were first consented into a study of symptom management, randomized to be offered acupuncture, and consented for acupuncture if they accepted. We are also conducting in-depth interviews and focus groups to assess evidence, context, and facilitators of key provider and hospital administration stakeholders.

DISCUSSION

Effectiveness research in "real-world" practice settings is needed to inform clinical decision-making and guide implementation of evidence-based acupuncture practices. To successfully provide clinical acupuncture services and maintain a rigorous research design, practice-based trials of acupuncture require careful planning and attention to setting-specific, contextual factors.

This trial has been registered in ClinicalTrials.gov. The identifier is NCT01988194, registered on November 5, 2013.

Evaluation of an antenatal acupuncture intervention as an adjunct therapy for antenatal depression (AcuAnteDep): study protocol for a pragmatic randomised controlled trial

BACKGROUND

Depressed pregnant women face difficulty navigating a course between the potentially serious consequences of leaving depression untreated and significant limitations associated with conventional therapies, such as foetal toxicity and teratogenicity. Preliminary evidence is suggestive that acupuncture may provide a safe and effective alternative treatment option for antenatal depression; however, additional research is required. The purpose of this study is to further investigate this treatment possibility, with an additional examination of a potential biomechanistic acupuncture effect.

METHODS/DESIGN

In this pragmatic randomised controlled trial, we will compare individually tailored, flexible antenatal depression-oriented acupuncture with equivalent attention progressive muscle relaxation and routine antenatal depression hospital care. Eligible women at 24 weeks of gestation with Edinburgh Postnatal Depression Scale scores of 13 or more will be recruited from 2 antenatal clinics in South Western Sydney, Australia. The recruitment goal of 96 is powered to demonstrate a significant difference in Edinburgh Postnatal Depression Scale score severity between acupuncture and usual care, with intervention groups receiving weekly 1-h treatments for 8 weeks from 24 to 31 weeks of gestation. Mental health and quality-of-life assessments will occur at study commencement, intervention weeks 4 and 8 and 6 weeks post-natally via the collection of completed Edinburgh Postnatal Depression Scale scores, Depression, Stress and Anxiety Scale scores and World Health Organisation Quality of Life Scale scores. Adjustment to mothering will also be evaluated at 6 weeks post-natally using the Being a Mother Scale. A putative biomechanistic effect of acupuncture on the oxytocinergic system will additionally be examined by comparing baseline salivary hormone levels with those measured at intervention weeks 4 and 8, as well as leucocyte oxytocin receptor expression at baseline and intervention week 8.

DISCUSSION

Ethical approval was received in February 2015, and recruitment is underway and expected to be completed in July 2016.

Effectiveness of acupuncture and related therapies for palliative care of cancer: overview of systematic reviews

Acupuncture and related therapies such as moxibustion and transcutaneous electrical nerve stimulation are often used to manage cancer-related symptoms, but their effectiveness and safety are controversial. We conducted this overview to summarise the evidence on acupuncture for palliative care of cancer. Our systematic review synthesised the results from clinical trials of patients with any type of cancer. The methodological quality of the 23 systematic reviews in this overview, assessed using the Methodological Quality of Systematic Reviews Instrument, was found to be satisfactory. There is evidence for the therapeutic effects of acupuncture for the management of cancer-related fatigue, chemotherapy-induced nausea and vomiting and leucopenia in patients with cancer. There is conflicting evidence regarding the treatment of cancer-related pain, hot flashes and hiccups, and improving patients' quality of life. The available evidence is currently insufficient to support or refute the potential of acupuncture and related therapies in the management of xerostomia, dyspnea and lymphedema and in the improvement of psychological well-being. No serious adverse effects were reported in any study. Because acupuncture appears to be relatively safe, it could be considered as a complementary form of palliative care for cancer, especially for clinical problems for which conventional care options are limited.

Comparative effectiveness of electro-acupuncture plus lifestyle modification treatment for patients with simple obesity and overweight: study protocol for a randomized controlled trial

BACKGROUND

Acupuncture is considered to be an effective and safe treatment for obese and overweight patients, although high-quality evidence regarding the effects of acupuncture on obesity are not conclusive. The aim of the current study is to investigate the effectiveness of electro-acupuncture plus lifestyle modification for treating obese and overweight patients, in comparison with lifestyle modification alone in China.

METHODS/DESIGN

To compare the effectiveness of acupuncture plus lifestyle modification, a 2-armed, controlled trial with randomization using minimization will be conducted on 150 simple obesity and overweight patients, aged 18-50 years, for a 36-week study duration. All patients will be randomly assigned to one of two groups and will receive either acupuncture plus lifestyle modification or lifestyle modification alone. Outcomes will be evaluated at baseline and at 4 weeks, 8 weeks, and 12 weeks during treatment as well as at 6-week, 12-week, and 24-week follow-up. The primary endpoint is change of body mass index (BMI) during the 12th week. Secondary endpoints are body weight; waist-to-hip ratio; biochemical tests including serum cholesterol (TC), triglyceride (TG) and high-density lipoprotein (HDL) levels; and answers to the Short Form 36 (SF-36) and the Impact of Weight on Quality of Life Questionnaire-Lite Version (IWQOL-Lite). Statistical analyses will be based on the intention-to-treat (ITT) principle. The main endpoint will be analyzed by analysis of covariance (ANCOVA), and the objective outcome results will be analyzed by logistic regression analysis. To avoid potential confounding factors, additional sensitivity analyses will be conducted following these statistical analyses.

DISCUSSION

This trial is the first to compare the effectiveness of acupuncture plus lifestyle modification for treating obesity relative to lifestyle modification treatment alone by using a pragmatic study design. We hope that the results of this study will contribute to advancing the current methodology of acupuncture trials for obesity and will facilitate the application of useful acupuncture strategies in real-world clinical settings.

Is acupuncture no more than a placebo? Extensive discussion required about possible bias

Numerous randomized controlled trials (RCTs) of acupuncture have been conducted in recent years. The results of several studies implied that acupuncture was only a powerful placebo; however, certain studies demonstrated that verum acupuncture had a greater effect than placebo and the mechanisms between a verum acupuncture group and a placebo/sham group were different. Researchers attempted to investigate the inherent factors that may potentially influence the results of trials. Certain problems observed in acupuncture RCTs also occurred in RCTs in other fields, including insufficient sample size, high dropout rates, inadequate follow-up and randomization. The study of acupuncture is so complex that specific methodological challenges are raised, which are frequently overlooked, including sham interventions, blinding, powerful placebo effects (even stronger than an inert pill) and variations in acupuncture administration. The aforementioned problems may contribute to bias, and researchers systematically attempt to solve these problems. The present review aimed to suggest techniques to design high-quality studies, minimize the placebo effect and optimize acupuncture administration in acupuncture studies. If these problems are addressed, then the results of acupuncture studies may be different.

Real world research: a complementary method to establish the effectiveness of acupuncture

Background

Acupuncture has been widely used in the management of a variety of diseases for thousands of years, and many relevant randomized controlled trials have been published. In recent years, many randomized controlled trials have provided controversial or less-than-convincing evidence that supports the efficacy of acupuncture. The clinical effectiveness of acupuncture in Western countries remains controversial.

Discussion

Acupuncture is a complex intervention involving needling components, specific non-needling components, and generic components. Common problems that have contributed to the equivocal findings in acupuncture randomized controlled trials were imperfections regarding acupuncture treatment and inappropriate placebo/sham controls. In addition, some inherent limitations were also present in the design and implementation of current acupuncture randomized controlled trials such as weak external validity. The current designs of randomized controlled trials of acupuncture need to be further developed. In contrast to examining efficacy and adverse reaction in a “sterilized” environment in a narrowly defined population, real world research assesses the effectiveness and safety of an intervention in a much wider population in real world practice. For this reason, real world research might be a feasible and meaningful method for acupuncture assessment.

Summary

Randomized controlled trials are important in verifying the efficacy of acupuncture treatment, but the authors believe that real world research, if designed and conducted appropriately, can complement randomized controlled trials to establish the effectiveness of acupuncture. Furthermore, the integrative model that can incorporate randomized controlled trial and real world research which can complement each other and potentially provide more objective and persuasive evidence.

Defining the quality of acupuncture: the case of acupuncture for cancer-related fatigue

BACKGROUND

The quality and dose of acupuncture used in a clinical trial affects the outcome, as with the quality and dose of any intervention. The dose of acupuncture treatment may be characterized by the frequency of treatment, needle type and depth, length of needle retention, point selection, and combination. The dose in trials of acupuncture has at times been described as low or inappropriate but is seldom assessed in systematic reviews of acupuncture trials. This article examines the research evaluating acupuncture for cancer-related fatigue to determine what characteristics of treatment may contribute to a quality acupuncture intervention.

METHODOLOGY

English and Chinese language databases were searched from inception to December 2013 for randomized controlled trials of acupuncture for the treatment of cancer-related fatigue. Assessment of the quality of the acupuncture intervention was undertaken using the domains and items from the NICMAN framework.

RESULTS

Seven studies with a total of 690 patients were included. Four of the studies were designed as feasibility or pilot studies, and the other 3 studies were described as "effectiveness" trials. The treatment paradigm for the active intervention was based on traditional Chinese medicine in all studies, yet few of the studies were explicit as to how the active intervention was justified within a traditional Chinese medicine paradigm. Acupuncture point prescriptions were developed by a small consensus panel or based on typical points and/or "clinical experience." No discussion of traditional Chinese medicine theory or literature review was reported in any studies. Acupuncture point location was adequately described in 4 of the 7 studies. Frequency of treatment was twice per week in 2 studies; all others were once per week. Two studies did not apply needle manipulation or stimulation, and no justification was given.

CONCLUSION

The 7 trials reviewed meet some criteria for a quality acupuncture intervention. However, frequently elements of the intervention were not addressed, and it is possible that the dosage trialed was suboptimal. Systematic reviews of acupuncture are likely to continue to be inconclusive while comparisons are conducted of heterogeneous interventions without providing.

Effectiveness of acupuncture for angina pectoris: a systematic review of randomized controlled trials

Background

The purpose of this systematic review is to assess the effectiveness of acupuncture for angina pectoris.

Methods

Eleven electronic databases were searched until January 2013. The study included randomized controlled trials that the effectiveness of acupuncture alone was compared to anti-angina medicines (in addition to conventional treatment) and the effectiveness of a combination of acupuncture plus anti-angina medicines was compared to anti-angina medicines alone. The trial selection, data extraction, quality assessment and data analytic procedures outlined in the 2011 Cochrane Handbook were involved.

Results

The study included 25 randomized controlled trials (involving 2,058 patients) that met our inclusion criteria. The pooled results showed that the number of patients with ineffectiveness of angina relief was less in the combined acupuncture-anti-angina treatment group than in the anti-angina medicines alone group (RR 0.33, 95% CI 0.23-0.47, p < 0.00001, I2 = 0%). Similarly, compared to the anti-angina medicines alone group, fewer patients in the combined treatment group showed no ECG improvement (RR 0.50, 95% CI 0.40-0.62, p < 0.00001, I2 = 0%). However, no differences were observed between acupuncture treatment alone and anti-angina medicines alone for both outcome measures. Only four trials mentioned adverse effects. One trial found no significant difference between acupuncture and Chinese medicine, and three reported no adverse events. The quality of the trials was found to be low.

Conclusions

The findings showed very low evidence to support the use of acupuncture for improving angina symptoms and ECG of angina patients. However, the quality of the trials included in this study was low. Large and rigorously designed trials are needed to confirm the potential benefit and adverse events of acupuncture.

What can comparative effectiveness research contribute to integrative health in international perspective?

The interest in Comparative Effectiveness Research (CER) in the international community is growing. A panel titled "What Can Comparative Effectiveness Research Contribute to Integrative Health in International Perspective?" took place at the 3rd International Research Congress on Integrative Medicine and Health in Portland, Oregon, in 2012. The presentations at this panel highlighted different perspectives on CER, including the funders' and the stakeholders' perspectives from the United States, as well as experiences with economic evaluations from Australia and pragmatic trials in Europe. The funders' perspective emphasized the need for innovation and controlling costs in large-scale studies. The stakeholder's perspective stressed the need to gather the input of stakeholders in shaping the framework for more informative, more decision-maker-driven research. Several examples of cost-effectiveness analyses were offered from Australia. The importance of balancing rigor and pragmatism was also discussed in a presentation of the efficacy-effectiveness continuum. A wide-ranging discussion explored additional questions concerning the translation of evidence into practice; the effect of pragmatic trials on funding or policy; evidentiary distinctions between and among pragmatic trials and traditional randomized clinical trials; and the multiple roles of stakeholders, particularly in generating new information and knowledge. The presentations and discussions showed that more development of methods is needed. This includes developments on study design and statistical approaches, as well as methods for stakeholder involvement and mechanisms to bring these results into practice.

Effectiveness guidance document (EGD) for Chinese medicine trials: a consensus document

Background

There is a need for more Comparative Effectiveness Research (CER) on Chinese medicine (CM) to inform clinical and policy decision-making. This document aims to provide consensus advice for the design of CER trials on CM for researchers. It broadly aims to ensure more adequate design and optimal use of resources in generating evidence for CM to inform stakeholder decision-making.

Methods

The Effectiveness Guidance Document (EGD) development was based on multiple consensus procedures (survey, written Delphi rounds, interactive consensus workshop, international expert review). To balance aspects of internal and external validity, multiple stakeholders, including patients, clinicians, researchers and payers were involved in creating this document.

Results

Recommendations were developed for “using available data” and “future clinical studies”. The recommendations for future trials focus on randomized trials and cover the following areas: designing CER studies, treatments, expertise and setting, outcomes, study design and statistical analyses, economic evaluation, and publication.

Conclusion

The present EGD provides the first systematic methodological guidance for future CER trials on CM and can be applied to single or multi-component treatments. While CONSORT statements provide guidelines for reporting studies, EGDs provide recommendations for the design of future studies and can contribute to a more strategic use of limited research resources, as well as greater consistency in trial design.

Traditional Chinese medicine: potential for clinical treatment of rheumatoid arthritis

Rheumatoid arthritis (RA) is a chronic debilitating autoimmune disease affecting people worldwide. Increasing numbers of RA patients in the west are resorting to various complementary and alternative medicine modalities for relief of symptoms and well-being. Herbal products and acupuncture representing traditional Chinese medicine (TCM) are two of the most commonly used forms of complementary and alternative medicine. Frequently, their efficacy against RA and safety have been inferred from anecdotal experience or pilot testing on a relatively small number of patients following inadequate study designs. Accordingly, significant efforts need to be invested in objectively testing TCM in clinical trials that are sufficiently powered, randomized, blinded, possess appropriate controls and follow standard criteria for assessment of the outcomes. In addition, the mechanisms underlying the immunomodulatory and other antiarthritic activities of TCM modalities need to be better defined. These efforts would help validate the scientific rationale for the use of TCM for the management of RA.

Influence of control group on effect size in trials of acupuncture for chronic pain: a secondary analysis of an individual patient data meta-analysis

Background

In a recent individual patient data meta-analysis, acupuncture was found to be superior to both sham and non-sham controls in patients with chronic pain. In this paper we identify variations in types of sham and non-sham controls used and analyze their impact on the effect size of acupuncture.

Methods

Based on literature searches of acupuncture trials involving patients with headache and migraine, osteoarthritis, and back, neck and shoulder pain, 29 trials met inclusion criteria, 20 involving sham controls (n = 5,230) and 18 non-sham controls (n = 14,597). For sham controls, we analysed non-needle sham, penetrating sham needles and non-penetrating sham needles. For non-sham controls, we analysed non-specified routine care and protocol-guided care. Using meta-regression we explored impact of choice of control on effect of acupuncture.

Findings

Acupuncture was significantly superior to all categories of control group. For trials that used penetrating needles for sham control, acupuncture had smaller effect sizes than for trials with non-penetrating sham or sham control without needles. The difference in effect size was −0.45 (95% C.I. −0.78, −0.12; p = 0.007), or −0.19 (95% C.I. −0.39, 0.01; p = 0.058) after exclusion of outlying studies showing very large effects of acupuncture. In trials with non-sham controls, larger effect sizes associated with acupuncture vs. non-specified routine care than vs. protocol-guided care. Although the difference in effect size was large (0.26), it was not significant with a wide confidence interval (95% C.I. −0.05, 0.57, p = 0.1).

Conclusion

Acupuncture is significantly superior to control irrespective of the subtype of control. While the choice of control should be driven by the study question, our findings can help inform study design in acupuncture, particularly with respect to sample size. Penetrating needles appear to have important physiologic activity. We recommend that this type of sham be avoided.

Patterns of traditional chinese medicine diagnosis in thermal laser acupuncture treatment of knee osteoarthritis

Knee osteoarthritis (OA) manifests with pain, joint stiffness, and limited function. In traditional Chinese medicine, knee OA is differentiated into three patterns: yang deficiency and cold coagulation, kidney deficiency, and blood stasis. The objective of this study was to determine whether yang deficiency cold coagulation patients respond better to thermal laser acupuncture treatment than do non-yang deficient patients. Fifty-two patients with OA were allocated to group A (yang deficient, n = 26) or B (non-yang deficient, n = 26). All patients received a 20-min thermal laser acupuncture treatment at acupoint Dubi (ST 35) three times a week for two weeks and twice a week for another four weeks. Outcome assessments were performed immediately after the first treatment, and at weeks 2, 6, and 10. Group A function scores were significantly better than those of Group B at weeks 2 (P = 0.049), 6 (P = 0.046), and 10 (P = 0.042), but no significant differences were found between the two groups in pain and stiffness scores at any time point. No significant adverse effect was observed. The combined 10.6 μm–650 nm laser treatment might be most beneficial to yang deficiency cold coagulation knee OA patients, particularly in improving function.

[Manual for the design of non-drug trials in primary care, taking account of Good Clinical Practice (GCP) criteria]

In recent years studies not falling under the German Pharmaceutical Law ("non-drug trials") have also been increasingly expected to be conducted according to Good Clinical Practice (GCP) in order to ensure that uniform standards are maintained for data quality and patient safety. However, simple transfer of the GCP criteria is not always possible and often not useful. Given the fact that research questions regarding non-drug interventions are common in primary care (e.g., general practice), the "Network for Clinical Studies in General Practice" has developed a manual for planning and conducting non-drug trials. This manual is based on the GCP guideline, taking account of the conditions and circumstances in primary care settings. Both structure and relevant content of the manual are presented in the article.
