Abstract
BACKGROUND Pragmatic acupuncture trials (PATs) are a research tool for assessing the effectiveness of acupuncture treatments in a real-world setting. This study aimed to provide a comprehensive methodological analysis of PATs using the PRECIS-2(PRagmatic Explanatory Continuum Indicator Summary-2) tool to determine their pragmatism. METHODS The MEDLINE, EMBASE, Cochrane Central Register for Controlled Trials, CINAHL, Allied and Complementary Medicine Database, China National Knowledge Infrastructure, VIP, WANFANG, Taiwan Periodical Literature Database, KoreaMed, KMbase, Research Information Service System, Oriental Medicine Advanced Searching Integrated System, CiNii and ClinicalTrials.gov were searched. The search included randomised controlled trials (RCTs) and protocols of RCTs that investigated all types of acupuncture and used self-declared pragmatic design. Two authors independently collected the basic information and characteristics of the studies and assessed their pragmatism using the nine PRECIS-2 domains and the additional domain of control. RESULTS A total of 93 studies were included. The means of eligibility, recruitment, organisation, primary outcome, primary analysis, and control domains were statistically larger than three and were shown to be pragmatic. The means of setting, flexibility:delivery, and follow-up domains were not greater than three and were shown to be non-pragmatic. For flexibility:adherence domain was inappropriate for assessment owing to insufficient information in the studies. CONCLUSIONS PATs were pragmatic in the domain of eligibility, recruitment, organisation, primary outcome, primary analysis, and control and were not pragmatic in the domain of setting, flexibility:delivery, and follow-up. Future PATs need to strengthen the pragmatism in the setting, flexibility:delivery, and follow-up domains and to describe the flexibility:adherence domain in more detail.

Survey analysis to determine the impact of evidence informed practice education upon East Asian medicine faculty clinical instruction and students' skills, knowledge, attitudes and behaviors within a master's degree program. BMC MEDICAL EDUCATION 2021; 21:256. [PMID: 33947384 PMCID: PMC8094568 DOI: 10.1186/s12909-021-02690-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Accepted: 04/23/2021] [Indexed: 06/12/2023]
Abstract
BACKGROUND Between 2013 and 2018 Pacific College of Health and Science (formerly Pacific College of Oriental Medicine) trained faculty and developed curriculum in evidence informed practice (EIP), with support from a grant from the National Institutes of Health (NIH). A three-credit (45 h) Foundations of EIP course, and online EIP learning modules (developed as part of a previous NIH R25 award), were used for faculty and student training. In addition, EIP was incorporated into 73% of the East Asian medicine degree program. Clinical integration of EIP in the College clinic was enhanced by improving access to reference sources, including additional EIP-related questions to the patient intake forms, requiring the use of a patient-centered outcome instrument, and assessing students' clinical EIP competencies. METHODS Master's degree students' self-reported EIP skills, knowledge, attitudes and behaviors were assessed before and after taking the Foundations of EIP course using a 17-question paper-based survey with an additional open-ended comments section. The survey was administered in 29 courses across all three Pacific College campuses. Clinical faculty self-reported EIP instruction, focusing on the EIP content and instructional approaches that were utilized, was evaluated on the New York City campus using a paper-based survey before and after changes were made to enhance the clinical integration of EIP. RESULTS A total of 1181 completed EIP-course surveys consisting of 657 pre-EIP course surveys and 524 post-EIP course surveys were analyzed. There was a statistically significant improvement in students' EIP skills, knowledge and behaviors after completing the EIP course. Students' perception of the importance of EIP was high before and after the EIP course. Little change in Faculty's EIP-related clinical instruction was evident following the EIP-related changes that were made to the Clinic. CONCLUSION Our study suggests that the three-credit (45 h) EIP course was effective at improving the EIP skills, knowledge and behaviors of this group of East Asian medicine students who were undertaking a master's degree that qualified them for licensure in acupuncture in the US. These students also demonstrated a high level of recognition for the importance of research and EIP both before and after the course. Training faculty clinical supervisors and providing greater access to evidence sources in the College clinic did not appear to increase EIP instructional activity.

Abstract
Acupuncture is a promising treatment for relieving pain and improving lower back function in clinical practice. However, evidence from randomized clinical trials (RCTs) remains controversial. Most RCTs conclude that acupuncture procedures for chronic low back pain (CLBP) had no significant difference in efficacy and belonged to placebo. We carefully reviewed and analyzed the methodology and implementation of sham acupuncture in RCTs. Controversial evidence of acupuncture for CLBP is only a microcosm of the evaluation methodological limitation of acupuncture. Inappropriate selection of sham acupuncture controls, rigorous RCT research models, and incorrect interpretation of results may contribute to negative evidence. Evaluating and disregarding the holistic efficacy of acupuncture with an explanatory RCT model based on evaluation drugs may be unwise. Moreover, sham acupuncture is often proven to be non-inert, unreasonable, and with low fidelity. Pitfalls of the explanatory RCT model and sham acupuncture design should be avoided. Establishing a new evaluation system that is in line with the clinical characteristics of acupuncture and obtaining high-quality evidence are difficult but promising tasks.

Abstract
We report a single-blinded randomized controlled trial comparing acupuncture to sham (non-penetrating) needling for relief of symptoms of basal thumb joint arthritis. Seventy acupuncture naive patients with basal thumb joint arthritis were randomized to receive true acupuncture or sham needling with 35 patients in each arm. Blinded baseline and post-treatment assessments included visual analogue pain scores for different grips and movement. Function was assessed using the Nelson questionnaire. Both groups showed statistically and clinically significant improvements in pain at week one post-treatment compared with baseline, but there was no difference between the treatment groups. The pain relief was comparable with published data for some standard treatments. Acupuncture did not perform better than sham needling in this study, indicating that pain relief may have been achieved through non-specific mechanisms. Level of evidence: I.

Abstract
Objectives: To train faculty and develop curricula in evidence-informed practice (EIP) within a Chinese medicine degree program. Setting: Pacific College of Oriental Medicine (New York). Design: Faculty EIP training was undertaken through utilization of online EIP modules, and development and completion of a 3-credit (45 h) online Foundations of EIP course. This was supplemented by faculty meetings and one-on-one support from department chairs. Curriculum development was undertaken by an EIP Curriculum Committee. The committee followed a modified Delphi process to develop EIP course learning outcomes (CLOs), and to make changes to the College's clinic policies and procedures. EIP assignments were developed for each course in accordance with the CLO. Results: Ninety-one percent of the faculty and 97% of clinical supervisors received formal EIP training. Thirty-five percent of all didactic faculty, 38% of faculty teaching courses with EIP incorporated, and 30% of clinical supervisors completed 10 or more h of EIP training during this project. Faculty also received informal EIP training through participation in department and general faculty meetings. Seventy-three percent of the Master's degree curriculum, inclusive of 40 didactic courses and fifteen 60-h clinic shifts, were modified to incorporate EIP. EIP CLOs and corresponding assignments were developed. Clinic intake forms were modified to facilitate undertaking EIP in the College clinic. Issues related to how EIP is defined in conjunction with the nature of available scientific research in Chinese medicine required discussion and resolution. Conclusions: Training faculty and developing curricula in EIP within Chinese medicine colleges has unique challenges that must be factored into the strategies and processes. Factors that contributed to the success of this project were having faculty drive the process, integrating EIP content within existing curricula, gradual exposure, identifying champions, relating EIP to practice building, and openly discussing opposing perspectives.

Abstract
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.

Abstract
Research on acupuncture has been muddled by attempts to bridge the ancient with the modern. Barriers to effectiveness research are reflected in recurring conflicts that include disagreement on use of the most basic terms, lack of standard intervention controls, and the absence of functional measures for assessing treatment effect. Acupuncture research has stalled at the "placebo barrier" wherein acupuncture is "no better than placebo." The most widely recognized comparative effectiveness research in acupuncture does not compare acupuncture treatment protocols within groups, thereby, mutating large scale effectiveness studies into large scale efficacy trials. Too often research in acupuncture attempts to tie outcomes to traditional belief systems thereby limiting usefulness of the research. The acupuncture research paradigm needs to focus more closely on a scientific definition of treatments and outcomes that compare protocols in terms of prevalent clinical issues such as relative effectiveness for treating pain.

Abstract
Background: Acupuncture use is increasing worldwide for many conditions, including movement disorders. Clinical research in acupuncture has also increased to test anecdotal reports of clinical benefits empirically and investigate potential mechanisms. Method: This article describes considerations for designing a double-blinded, randomized, placebo-controlled clinical trial of acupuncture for fatigue in Parkinson's disease (PD) and describes the current authors' experience in the implementation and early conduct of this trial. Relevant literature is also reviewed to provide guidance for other researchers seeking to perform clinical research relevant to PD and related disorders. Results: Trial design should be driven by a well-defined research question and sufficient detail to meet Standards for Reporting Interventions in Clinical Trials of Acupuncture criteria when a trial is complete. Important items for review include: randomization and blinding; recruitment and participant selection; sham methodology choice; staff training; and practical implementation of study procedures. Sample forms used for the current authors' trial are shared. Conclusions: High-quality clinical trials of acupuncture can provide valuable information for clinicians, patients, and policymakers. Acupuncture trials differ in critical ways from pharmaceutical trials and might require additional considerations regarding design and implementation. Adequate preparation for the unique challenges of acupuncture studies can improve trial implementation, design, efficiency, and impact.

Abstract
Acupuncture care delivered pragmatically as an adjunct to conventional care may lead to improvements in quality of life and alleviation of conventional treatment-related side effects among breast cancer patients. Patient perceptions and expectations of treatment and the therapeutic relationship inherent to acupuncture care could modify treatment effects. The aim of this study was to design a rigorous feasibility study in preparation for trial to evaluate the effects of acupuncture care (a whole system) on the fatigue experienced by patients undergoing conventional treatment of their breast cancer. Phase 1 included the development of a treatment protocol for a short course of acupuncture care for patients with breast cancer undergoing chemotherapy. Defining best practice in this context will ensure that the intervention tested will have meaning and validity for all professional acupuncturists. Phase 2 will be a randomized feasibility pilot study using the acupuncture treatment protocol for 40 patients with breast cancer undergoing chemotherapy. The study will use a mixed-methods approach involving both qualitative and quantitative assessments. Outcome assessment will include validated measures for fatigue, quality of life, and depression. The proposed study will tell us what effects of acupuncture care are important to the patient and address acupuncture as it is practiced in the real world. Results from this study will enable a definitive randomized controlled trial to evaluate the effectiveness of acupuncture care for fatigue in breast cancer patients undergoing chemotherapy.

Abstract
OBJECTIVES To evaluate the efficacy of an individualised acupuncture protocol for patients with fibromyalgia. METHODS Randomised controlled multicentre trial, blinded to participants and to data analysts. Conducted in three primary care centres in southern Spain. A total of 164 participants aged over 17 years and diagnosed with fibromyalgia were enrolled in this trial; 153 participants completed the study. Participants were randomly assigned to either the real intervention (individualised acupuncture, IA) or the sham intervention (sham acupuncture, SA). In both the IA and SA groups, one session per week (lasting 20 min) was provided, in addition to usual pharmacological treatment. The primary outcome was change in pain intensity at 10 weeks. RESULTS Intention-to-treat analysis revealed that the decrease in pain intensity at 10 weeks was greater (p=0.001) in the IA group (-41.0%, 95% CI -47.2% to -34.8%) than in the SA group (-27.1%, 95% CI -33.2% to -20.9%). During the follow-up period, significant differences (p<0.01) in favour of the IA group persisted at 12 months (IA: -19.9%, 95% CI -24.6% to -15.1%; vs SA: -6.2%, 95% CI -11.2% to -1.2%). CONCLUSIONS Individualised acupuncture treatment in primary care in patients with fibromyalgia proved efficacious in terms of pain relief, compared with placebo treatment. The effect persisted at 1 year, and its side effects were mild and infrequent. Therefore, the use of individualised acupuncture in patients with fibromyalgia is recommended.

Abstract
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.

Abstract
BACKGROUND Acupuncture is increasingly used as an additional treatment for patients with Parkinson's disease (PD). METHODS In this functional magnetic resonance imaging study, brain activation in response to acupuncture in a group of 12 patients with PD was compared with a group of 12 healthy participants. Acupuncture was conducted on a specific acupoint, the right GB 34 (Yanglingquan), which is a frequently used acupoint for motor function treatment in the oriental medical field. RESULTS Acupuncture stimulation on this acupoint activates the prefrontal cortex, precentral gyrus, and putamen in patients with PD; areas that are known to be impaired in patients with PD. Compared with healthy participants, patients with PD showed significantly higher brain activity in the prefrontal cortex and precentral gyrus, especially visible in the left hemisphere. CONCLUSIONS The neuroimaging results of our study suggest that in future acupuncture research; the prefrontal cortex as well as the precentral gyrus should be treated for symptoms of Parkinson's disease and that GB 34 seems to be a suitable acupoint. Moreover, acupuncture evoked different brain activations in patients with Parkinson's disease than in healthy participants in our study, stressing the importance of conducting acupuncture studies on both healthy participants as well as patients within the same study, in order to detect acupuncture efficacy.

Abstract
BACKGROUND In the last 2 decades there has been a large increase in publications on complementary and alternative medicine (CAM). However, CAM research methodology was heterogeneous and often of low quality. The aim of this systematic review was to investigate scientific publications with regards to general issues, concepts and strategies. We also looked at research priorities and methods employed to evaluate the clinical and epidemiological research of CAM in the past to identify the basis for consensus-based research strategies. METHODS We performed a systematic literature search for papers published between 1990 and 2010 in 7 electronic databases (Medline, Web of Science, PsychArticles, PsycInfo, CINAHL, EMBASE and Cochrane Library) on December 16 and 17, 2010. In addition, experts were asked to nominate relevant papers. Inclusion criteria were publications dealing with research methodology, priorities or complexities in the scientific evaluation of CAM. All references were assessed in a multistage process to identify relevant papers. RESULTS From the 3,279 references derived from the search and 98 references contributed by CAM experts, 170 papers fulfilled the criteria and were included in the analysis. The following key issues were identified: difficulties in past CAM research (e.g., randomisation, blinding), utility of quantitative and qualitative research methods in CAM, priority setting in CAM research and specific issues regarding various CAM modalities. CONCLUSIONS Most authors vote for the use of commonly accepted research methods to evaluate CAM. There was broad consensus that a mixed methods approach is the most suitable for gathering conclusive knowledge about CAM.

Bishop FL, Lewith GT. Patients' preconceptions of acupuncture: a qualitative study exploring the decisions patients make when seeking acupuncture. Altern Ther Health Med 2013; 13:102. [PMID: 23664032 PMCID: PMC3658911 DOI: 10.1186/1472-6882-13-102] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2012] [Accepted: 05/09/2013] [Indexed: 12/30/2022]
Abstract
Background Like any other form of healthcare, acupuncture takes place in a particular context which can enhance or diminish treatment outcomes (i.e. can produce contextual effects). Patients’ expectations of acupuncture might be an important component of contextual effects, but we know relatively little about the origins and nature of patients’ expectations or wider preconceptions about acupuncture. Our aim was to identify the processes the underpin patients’ decisions to try acupuncture and thus begin to tease out the origins and nature of patients’ preconceptions. Methods One-off semi-structured interviews were conducted with a purposive, varied sample of 35 adults who had tried acupuncture for various conditions. Interviews explored people’s experiences of acupuncture treatment and techniques from framework and inductive thematic analysis were used to relate the data to the research question. Results We identified four distinct processes within participants’ accounts of deciding to try acupuncture: establishing a need for treatment, establishing a need for a new treatment, deciding to try acupuncture, and finding an acupuncturist. Family, friends and health care professionals played a role in these processes, providing support, advice, and increasing people’s general familiarity with acupuncture. When they came to their first acupuncture appointment, participants had hopes, concerns, and occasionally concrete expectations as to the nature of acupuncture treatment and its likely effects. Conclusions Existing theories of how context influences health outcomes could be expanded to better reflect the psychological components identified here, such as hope, desire, optimism and open-mindedness. Future research on the context of acupuncture should consider these elements of the pre-treatment context in addition to more established components such as expectations. There appears to be a need for accessible (i.e. well-disseminated), credible, and individualised, patient-centred materials that can allay people’s concerns about the nature of acupuncture treatment and shape realistic hopes and expectations.

Abstract
AIMS Aims were to determine the effectiveness of acupuncture and Chinese herbs as treatments for depression, and to assess beliefs, attitudes and treatment experience. METHOD Participants received acupuncture or acupuncture and Chinese herbs combined for five weeks. Acupuncture was given for 30 min twice a week and herbs taken three times a day. A Beliefs and Attitudes questionnaire was administered at baseline and Treatment Experience questionnaire post treatment. Outcome measure was improvement in depressive symptoms at the end of treatment period. RESULTS Nineteen participants completed 5 weeks of treatment, 12 in the acupuncture group and 7 in the combined group. Treatment significantly improved depressive symptoms, however, there were no differences between groups. At baseline, participants were positive about the perceived effectiveness of treatment, and treatment experiences were positive. CONCLUSIONS Acupuncture was effective in reducing depressive symptoms. However, herbs did not have an additional treatment effect. Beliefs and attitudes were positive.

Abstract
The rising incidence of chronic disease and stress-related illness in the West, coupled with an expanding awareness of the unwanted side effects of pharmaceutical treatment, has led to an increased utilization of acupuncture as a contemporary health care option. This increase in utilization, in turn, has paralleled a response to the call for evidence, with the result that acupuncture is now supported by a broad range of surveys of safety, clinical trials and basic science studies of physiologic action. The combined impact of these studies is linked to a growing acceptance of this traditional medical practice. The present review takes a wide-angle look at these three major areas of acupuncture research, namely: safety and the risks of serious adverse events; clinical efficacy and effectiveness; and physiologic action. We identify advances in knowledge and present a point counterpoint approach to controversial issues, with the aim of offering clarification if not a measure of resolution.

Abstract
In clinical acupuncture, when acupuncture points are stimulated, several types of reflex responses can be evoked. Consequently, different categories of physiological responses are induced, which include changes in the activities of internal organs and tissues. The acupuncture point Sanyinjiao (SP6) has been used successfully to treat different human gastrointestinal conditions. The aim of this work was to investigate the effects of end-organ response induced by acupuncture point SP6 on the bioavailability of the radiopharmaceutical sodium pertechnetate ( Na 99 m TcO 4) in Wistar rats. Healthy rats were allocated into 2 groups, control-CG and treated-TG. TG was bilaterally stimulated at acupuncture point SP6 with stainless steel needles. Ocular plexus administration of Na 99 m TcO 4 (3.7MBq) was carried out 10 min after every needle insertion in all animals. Ten minutes later, the animals were killed, the organs were isolated, the radioactivity was determined in a well gamma counter, and the percentage of injected dose per gram of tissue (%ID/g) was determined for each organ. The %ID/g was significantly altered ( p < 0.05) in the small intestine of TG (0.56 ± 0.09) when compared to CG (0.82 ± 0.18). These results may suggest that this stimulation might induce physiological responses capable of altering the bioavailability of the radiopharmaceutical sodium pertechnetate. These findings aid in providing a better understanding of acupuncture and its effects on various organs and tissues.

Abstract
BACKGROUND Pain is the most common reason that patients present to an emergency department (ED) and is often inadequately managed. Evidence suggests that acupuncture is effective for pain relief, yet it is rarely practiced in the ED. The current study aims to assess the efficacy of acupuncture for providing effective analgesia to patients presenting with acute low back pain, migraine and ankle sprain at the EDs of four hospitals in Melbourne, Australia. METHOD The study is a multi-site, randomized, assessor-blinded, controlled trial of acupuncture analgesia in patients who present to an ED with low back pain, migraine or ankle sprain. Patients will be block randomized to receive either acupuncture alone, acupuncture as an adjunct to pharmacotherapy or pharmacotherapy alone. Acupuncture will be applied according to Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA). Pain after one hour, measured using a visual analogue scale (VAS), is the primary outcome. Secondary outcomes measures include the following instruments; the Oswestry low back pain disability questionnaire, 24-hour Migraine Quality of Life questionnaire and Patient's Global Assessment of Ankle Injury Scale. These measures will be recorded at baseline, 1 hour after intervention, each hour until discharge and 48±12 hours of ED discharge. Data will also be collected on the safety and acceptability of acupuncture and health resource utilization. DISCUSSION The results of this study will determine if acupuncture, alone or as an adjunct to pharmacotherapy provides effective, safe and acceptable pain relief for patients presenting to EDs with acute back pain, migraine or ankle sprain. The results will also identify the impact that acupuncture treatment may have upon health resource utilisation in the ED setting.

Abstract
This qualitative study explored non-specific influences on participation in, and outcomes of, a randomised controlled trial. It was nested within a single-blind clinical trial of western acupuncture which compared real acupuncture with two types of placebo control administered to National Health Service (NHS) patients awaiting hip and knee replacement surgery in England. Data collection (2004-2008) was based on narrative-style interviews and participant observation. The results indicate that trial recruitment and retention depend on a set of convictions forged largely as a result of contextual factors peripheral to the intervention, including the friendliness and helpfulness of research centre staff and status of the administering practitioner. These convictions also influence the reporting of the study outcomes, particularly if participants experience uncertainties when choosing an appropriate response. The findings suggest that participants in clinical trials are actively involved in shaping the research process, rather than passive recipients of treatment. Thus the outcomes of trials, notably those involving contact interventions, should be regarded not as matters of fact, but as products of complex environmental, social, interpretive and biological processes. In this paper, we develop and present a 'theory of active research participation' which offers a framework for understanding the impact of non-specific processes in clinical trials.

Abstract
Methodological problems of acupuncture trials focus on adequate placebo controls. In this trial we evaluated the use of sham laser acupuncture as a control procedure. Thirty-four healthy volunteers received verum laser (invisible infrared laser emission and red light, 45 s and 1 J per point) and sham laser (red light) treatment at three acupuncture points (LI4, LU7 and LR3) in a randomized, double-blinded, cross-over design. The main outcome measure was the ratio of correct to incorrect ratings of treatment immediately after each session. The secondary outcome measure was the occurrence of deqi-like sensations at the acupuncture points and their intensity on a 10-fold visual analog scale (VAS; 10 being the strongest sensible sensation). We pooled the results of three former trials to evaluate the credibility of sham laser acupuncture when compared to needle acupuncture. Fifteen out of 34 (44%) healthy volunteers (age: 28 ± 10.7 years) identified the used laser device after the first session and 14 (41%) after the second session. Hence, both treatments were undistinguishable (P = .26). Deqi-like sensations occurred in 46% of active laser (2.34 VAS) and in 49.0% of sham laser beams (2.49 VAS). The credibility of sham laser was not different from needle acupuncture. Sham laser acupuncture can serve as a valid placebo control in laser acupuncture studies. Due to similar credibility and the lack of sensory input on the peripheral nervous system, sham laser acupuncture can also serve as a sham control for acupuncture trials, in order to evaluate needling effects per se.

Abstract
It is important that integrative healthcare research be conducted to optimize the effectiveness, safety, costs, and social and economic impact of prospective, personalized, patient-centered, comprehensive, and holistic healthcare that focuses on well-being as well as disease management, and that the research itself be well understood. The scope of this research extends beyond evaluation of specific therapies, to include evaluations of multimodality whole system intervention, practitioner-patient relationships, patient goals and priorities, promoting self-care and resilience, personalized diagnostic and therapeutic measures, practitioner well-being, the comparative effectiveness of different educational and outreach strategies in improving health and healthcare, and the environmental/social causes and consequence of health and healthcare. In this paper, we describe the state of the science of research on integrative healthcare, research needs, and opportunities offered by cutting-edge research tools. We propose a framework for setting priorities in integrative health research, list areas for discussion, and pose a few questions on a future research agenda.

Abstract
OBJECTIVES One out of 4 patients visiting a general practitioner reports of a sore throat associated with pain on swallowing. This study was established to examine the immediate pain alleviating effect of a single point acupuncture treatment applied to the large intestine meridian of patients with sore throat. PATIENTS AND METHODS Sixty patients with acute tonsillitis and pharyngitis were enrolled in this randomized placebo-controlled trial. They either received acupuncture, or sham laser acupuncture, directed to the large intestine meridian section between acupuncture points LI 8 and LI 10. The main outcome measure was the change of pain intensity on swallowing a sip of water evaluated by a visual analog scale 15 minutes after treatment. A credibility assessment regarding the respective treatment was performed. RESULTS The pain intensity for the acupuncture group before and immediately after therapy was 5.6+/-2.8 and 3.0+/-3.0, and for the sham group 5.6+/-2.5 and 3.8+/-2.5, respectively. Despite the articulation of a more pronounced improvement among the acupuncture group, there was no significant difference between groups (Delta=0.9, confidence interval: -0.2-2.0; P=0.12; analysis of covariance). Patients' satisfaction was high in both treatment groups. The study was prematurely terminated due to a subsequent lack of suitable patients. DISCUSSION A single acupuncture treatment applied to a selected area of the large intestine meridian was no more effective in the alleviation of pain associated with clinical sore throat than sham laser acupuncture applied to the same area. Hence, clinically relevant improvement could be achieved. Pain alleviation might partly be due to the intense palpation of the large intestine meridian. The benefit of a comprehensive acupuncture treatment protocol in this condition should be subject to further trials.

Abstract
Background Acute herpes zoster is a prevalent condition. One of its major symptoms is pain, which can highly influence patient's quality of life. Pain therapy is limited. Acupuncture is supposed to soften neuropathic pain conditions and might therefore act as a therapeutic alternative. Objective of the present study is to investigate whether a 4 week semi-standardised acupuncture is non-inferior to sham laser acupuncture and the anticonvulsive drug gabapentine in the treatment of pain associated with herpes zoster. Methods/Design Three-armed, randomised, placebo-controlled trial with a total follow-up time of 6 months. Up to estimated 336 patients (interim analyses) with acute herpes zoster pain (VAS > 30 mm) will be randomised to one of three groups (a) semi-standardised acupuncture (168 patients); (b) gabapentine with individualised dosage between 900–3600 mg/d (84 patients); (c) sham laser acupuncture. Intervention takes place over 4 weeks, all patients will receive analgesic therapy (non-opioid analgesics: metamizol or paracetamol and opioids: tramadol or morphine). Therapy phase includes 4 weeks in which group (a) and (c) consist of 12 sessions per patient, (b) visits depend on patients needs. Main outcome measure is to assess the alteration of pain intensity before and 1 week after treatment sessions (visual analogue scale VAS 0–100 mm). Secondary outcome measure are: alteration of pain intensity and frequency of pain attacks; alteration of different aspects of pain evaluated by standardised pain questionnaires (NPI, PDI, SES); effects on quality of life (SF 36); analgesic demand; alteration of sensoric perception by systematic quantitative sensory testing (QST); incidence of postherpetic neuralgia; side effects and cost effectiveness. Credibility of treatments will be assessed. Discussion This study is the first large-scale randomised placebo controlled trial to evaluate the efficacy of acupuncture compared to gabapentine and sham treatment and will provide valuable new information about the clinical and physiological effects of acupuncture and gabapentine in the treatment of acute herpes zoster pain. The study has been pragmatically designed to ensure that the study findings can be implemented into clinical practice if acupuncture can be shown to be an effective treatment strategy in acute herpes zoster pain.

Abstract
BACKGROUND Acupuncture is a popular complementary and alternative treatment for chronic back pain. Recent European trials suggest similar short-term benefits from real and sham acupuncture needling. This trial addresses the importance of needle placement and skin penetration in eliciting acupuncture effects for patients with chronic low back pain. METHODS A total of 638 adults with chronic mechanical low back pain were randomized to individualized acupuncture, standardized acupuncture, simulated acupuncture, or usual care. Ten treatments were provided over 7 weeks by experienced acupuncturists. The primary outcomes were back-related dysfunction (Roland-Morris Disability Questionnaire score; range, 0-23) and symptom bothersomeness (0-10 scale). Outcomes were assessed at baseline and after 8, 26, and 52 weeks. RESULTS At 8 weeks, mean dysfunction scores for the individualized, standardized, and simulated acupuncture groups improved by 4.4, 4.5, and 4.4 points, respectively, compared with 2.1 points for those receiving usual care (P < .001). Participants receiving real or simulated acupuncture were more likely than those receiving usual care to experience clinically meaningful improvements on the dysfunction scale (60% vs 39%; P < .001). Symptoms improved by 1.6 to 1.9 points in the treatment groups compared with 0.7 points in the usual care group (P < .001). After 1 year, participants in the treatment groups were more likely than those receiving usual care to experience clinically meaningful improvements in dysfunction (59% to 65% vs 50%, respectively; P = .02) but not in symptoms (P > .05). CONCLUSIONS Although acupuncture was found effective for chronic low back pain, tailoring needling sites to each patient and penetration of the skin appear to be unimportant in eliciting therapeutic benefits. These findings raise questions about acupuncture's purported mechanisms of action. It remains unclear whether acupuncture or our simulated method of acupuncture provide physiologically important stimulation or represent placebo or nonspecific effects.

Abstract
The objective of our study was to review the effectiveness of needle acupuncture in treating the common and disabling problem of pelvic and back pain in pregnancy. Two small trials on mixed pelvic/back pain and 1 large high-quality trial on pelvic pain met the inclusion criteria. Acupuncture, as an adjunct to standard treatment, was superior to standard treatment alone and physiotherapy in relieving mixed pelvic/back pain. Women with well-defined pelvic pain had greater relief of pain with a combination of acupuncture and standard treatment, compared to standard treatment alone or stabilizing exercises and standard treatment. We used a narrative synthesis due to significant clinical heterogeneity between trials. Few and minor adverse events were reported. We conclude that limited evidence supports acupuncture use in treating pregnancy-related pelvic and back pain. Additional high-quality trials are needed to test the existing promising evidence for this relatively safe and popular complementary therapy.

Abstract
Acupuncture is an ancient Chinese therapy with its mode of action unclear and efficacy inconclusive. A lack of attention given to the role of psychosocial context presented in clinical provision of acupuncture may mainly account for the current dilemma in acupuncture research. This psychosocial context induces various cognitive and affective processes in the patient while receiving this treatment. On the basis of the analysis of these psychological factors involved in clinical provision of acupuncture and in light of prior studies on the placebo effect, the author hypothesizes that acupuncture works through potentiation and modulation of a highly organized and somatotopic network of endogenous opioids that links expectation, attention and body schema. This hypothesis, which focuses on the contextual factors involved in clinical provision of acupuncture, has immediate clinical and experimental implications and will take the acupuncture debate much further forward.

Abstract
OBJECTIVE The aim of this study was to compare the results of healthy volunteers with patients in chronic pain, in terms of acupuncture needle sensation. The search for a credible mechanism that underpins the effect of acupuncture in pain has recently involved the use of brain imaging techniques in an attempt to identify the neural correlates involved in pain control. Such studies have usually enrolled healthy participants rather than patients. This practice might be inappropriate as we are unsure if we can generalize from healthy volunteers to patients in chronic pain. METHOD This paper describes a comparison of data obtained from 2 small randomized controlled studies, 1 involving patients with chronic pain and the other which recruited healthy volunteers. Both studies used real acupuncture and a nonpenetrating "placebo" needle in a crossover design. The outcome studied in this paper was a comprehensive needling sensation questionnaire. RESULTS There was a difference in the sensations experienced by patients as compared with healthy volunteers. Patients tended to feel much stronger sensation. Neither group differed in distinguishing between real and placebo needling. However, patients were more likely to state that both needles were real, whereas healthy participants were more likely to suggest that neither were real. DISCUSSION It is concluded that if the nature of the sensation felt is of importance, then it might be inappropriate to recruit healthy volunteers in lieu of patients and a larger study is required to clarify this.

Abstract
BACKGROUND Oriental medicine (OM) is widely practiced internationally and embraces many schools of thought. Western medical research is currently struggling to understand OM in purely biomedical terms, with limited success. OBJECTIVE We propose a research model for applying Western research methodologies to OM in a way that respects its theory and modes of clinical application. This would facilitate systematic investigations of OM's specific assumptions and make explicit the way OM studies could build on each other. METHODS To develop this model, the authors extracted key assumptions of Western research methodology germane to clinical research, put them in a developmentally logical sequence, and related them to the diagnostic and clinical processes of OM. RESULTS The model categorizes studies into seven levels. Foundation studies (level one) establish the conceptual basis for OM research by establishing the internal validity of its basic "truth statements." Measurement studies (level two) determine how OM identifies and measures diagnostic indicators, treatment outcomes, and other basic aspects of health. Group studies (level three) describe populations in ways meaningful to their health. Pattern/diagnosis studies (level four) identify and define OM patterns of disharmony. Treatment technique studies (level five) describe particular techniques or principles of treatment, their indications, and rationale. Treatment effectiveness studies (level six) evaluate techniques of treatment, often by comparing the results of one technique with those of another in similar patients. Systematic reviews (level seven) draw together studies on the same topic to see if conclusions are thereby strengthened. CONCLUSION The levels can be used to establish relationships between already published studies, determine if sufficient background research has been done to enable a study idea to be carried out, and generate ideas for future studies.
