Development of an instrument to assess the quality of acupuncture: results from a Delphi process

Delivery of acupuncture in clinical trials: Research acupuncturists’ perspectives

Delivery of acupuncture in the setting of a clinical trial is a unique practice that diverges significantly from the delivery of acupuncture in a real-world clinical setting. Research acupuncturists, particularly those trained in traditional Chinese medicine (TCM), are often required to set aside valued precepts of traditional care, including diagnosing imbalances, individualizing treatment, and forging a therapeutic relationship with patients. TCM-trained acupuncturists express mixed feelings about participating in clinical trials. Many are eager to play a vital role in the advancement of acupuncture science and appreciate the need for strict protocol adherence to minimize bias. However, the acupuncturist(s) may also have concerns about clinical trial methodology, including but not limited to the delivery of a control condition, e.g., sham acupuncture. Investigators should anticipate certain questions and even a level of resistance to the requirements of research among acupuncturists and be prepared to address them. This manuscript presents a brief review of the subjective experience of the research acupuncturist within the available scientific literature as it pertains to the delivery of active and sham clinical research protocols. Our goals are to better understand the perspectives of acupuncturists who may participate in clinical research, so that their concerns may be addressed in study design and methodology. To that end, we suggest the creation of a novel training program specifically for clinical trial acupuncturists, intended for qualified TCM- and Western-trained practitioners, that would help to standardize the research acupuncturist's role and help to strengthen the design and execution of acupuncture studies.

Approach to Assess Adequacy of Acupuncture in Randomized Controlled Trials: A Systematic Review

OBJECTIVE

To summarize and identify the available instruments/methods assessing the adequacy of acupuncture in randomized controlled trials (RCTs) for proposing a new improved instrument.

METHODS

A systematic literature search was carried out in 7 electronic databases from inception until 21st November 2022. Any study evaluating the adequacy or quality of acupuncture, specifying specific acupuncture treatment-related factors as criteria of subgroup analysis, or developing an instrument/tool to assess the adequacy or quality of acupuncture in an RCT was included. Basic information, characteristics and contents of acupuncture adequacy assessment were presented as frequencies and percentages.

RESULTS

Forty studies were included in this systematic review. Thirty-five studies (87.50%) were systematic reviews, none of which used formal methods to develop the assessment instruments/methods of acupuncture adequacy; of 5 methodological studies, only 1 study used a relatively formal method. Thirty-two studies (82.05%) assessed the components of acupuncture, while 7 (17.95%) assessed the overall quality of acupuncture. An independent assessment instrument/method was used to assess acupuncture adequacy in 29 studies (74.35%), whereas as one part of a methodological quality assessment scale in 10 (25.65%). Only 9 (23.00%) studies used the assessment results for subgroup analysis, sensitivity analysis or the criteria for inclusion in the meta-analysis.

CONCLUSION

Assessment contents for adequacy or quality of acupuncture in RCTs hadn't still reached consensus and no widely used assessment tools appeared. The methodology of available assessment instruments/scales is far from formal and rigorous. A new instrument/tool assessing adequacy of acupuncture should be developed using a formal method.

Does acupuncture therapy affect peripheral inflammatory cytokines of major depressive disorder? A protocol for the systematic review and meta-analysis

Background

Acupuncture is widely used as adjuvant therapy for major depressive disorder (MDD). There is robust evidence that inflammation is closely associated with MDD. To date, only a few numbers of studies have investigated the potential relationship between acupuncture and the change of inflammatory biomarkers in patients with MDD. Additionally, the results are inconsistent among studies. The current study aims to provide a comprehensive, systematic review of the association between acupuncture and changes in peripheral inflammation of patients with MDD, and clarify the alterations of inflammatory cytokines before and after acupuncture treatment by meta-analysis.

Methods and analysis

This study will be conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eligible randomized controlled trials (RCTs) reporting acupuncture, with inflammatory cytokines as the outcome measured before and after intervention in patients with MDD, were searched in electronic databases, such as PubMed, Embase, Cochrane, SINOMED, Wanfang, China national knowledge infrastructure (CNKI), and Chongqing VIP (CQVIP). Primary outcomes of interest will be validated to measure the levels of inflammatory cytokines before and after acupuncture treatment in patients with MDD.

Discussion

Acupuncture can drive anti-inflammatory effects, as well as symptom changes in MDD, which may represent a viable, multi-faceted treatment approach in MDD.

Electroacupuncture inhibits the interaction between peripheral TRPV1 and P2X3 in rats with different pathological pain

Chronic pain is regarded to be one of the common and refractory diseases to cure in the clinic. One hundred Hz electroacupuncture (EA) is commonly used for inflammatory pain and 2 Hz for neuropathic pain possibly by modulating the transient receptor potential vanilloid subtype 1 (TRPV1) or the purinergic P2X3 related pathways. To clarify the mechanism of EA under various conditions of pathological pain, rats received a subcutaneous administration of complete Freund's adjuvant (CFA) for inflammatory pain and spared nerve injury (SNI) for neuropathic pain. The EA was performed at the bilateral ST36 and BL60 1 d after CFA or SNI being successfully established for 3 consecutive days. The mechanical hyperalgesia test was measured at baseline, 1 d after model establishment, 1 d and 3 d after EA. The co-expression changes, co-immunoprecipitation of TRPV1 and P2X3, and spontaneous pain behaviors (SPB) test were performed 3 d after EA stimulation. One hundred Hz EA or 2Hz EA stimulation could effectively down-regulate the hyperalgesia of CFA or SNI rats. The increased co-expression ratio between TRPV1 and P2X3 at the dorsal root ganglion (DRG) in two types of pain could be reduced by 100Hz or 2Hz EA intervention. While 100Hz or 2Hz EA was not able to eliminate the direct physical interaction between TRPV1 and P2X3. Moreover, EA could significantly inhibit the SPB induced by the co-activation of peripheral TRPV1 and P2X3. All results indicated that EA could significantly reduce the hyperalgesia and the SPB, which was partly related to inhibiting the co-expression and indirect interaction between peripheral TRPV1 and P2X3.

Protocol for Infant Massage in Home Settings: An e-Delphi Approach for Consensus Guidance Integrating Traditional Wisdom with Modern Medicine

Infant massage is a highly prevalent traditional practice in India and other parts of Asia. Clear guidance on safe and effective uses of infant massage is lacking especially in the contemporary times when the traditional knowledge is on the verge of extinction and preparations may differ from in the past. This paper presents a consensus guidance in the form of a standardized protocol for routine massage of infants in home settings. Furthermore, a feasible method to develop an integrative protocol involving traditional and modern medicine experts is described. A modified e-Delphi method was used to develop the protocol. A group of seventeen experts, including academicians and practitioners from disciplines as modern paediatrics, Ayurveda paediatrics, Physiotherapy and Naturopathy participated in three rounds of a Delphi study to evolve the consensus guidance. The present protocol for massage of infants born beyond 34 weeks of gestation and weighing above 1.8 kg is recommended for use by care givers. This provides guidance on the preparation for infant massage such as when to begin massaging the infant, checking fitness of the infant for massage, the appropriate time, environment, person and substance for infant massage and a detailed description of the procedure for infant massage. Paediatricians, obstetricians and other child care practitioners can use this protocol to guide care givers on how to peform infant massage.

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.

Optimal acupoint and session of acupuncture for patients with chronic prostatitis/chronic pelvic pain syndrome: a meta-analysis

Background

The study aims to perform a meta-analysis of published trials and evaluate the efficacy of acupuncture on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) by symptom score reduction, optimal acupuncture session, and most frequently used acupoints.

Methods

A literature search was performed for randomized controlled trials (RCTs) comparing efficacy of acupuncture with sham acupuncture or standard medication on CP/CPPS. The primary outcome was the reduction of National Institute of Health-Chronic Prostatitis Index (NIH-CPSI) total score and its subscales. The optimal acupuncture session to reach its clinical efficacy and most common compatibility rule of acupoints were also evaluated.

Results

Ten trials involving 770 participants were included. Meta-analysis showed compared with sham acupuncture, acupuncture yielded significant reduction in NIH-CPSI total score [weighted mean difference (WMD): 7.28, 95% confidence interval (95% CI): 5.69-8.86), and provided better pain relief (WMD: 3.57, 95% CI: 2.07-5.08), urinary symptoms improvement (WMD: 1.68, 95% CI: 1.13-2.22), and quality of life (QOL) (WMD: 2.38, 95% CI: 1.41-3.36). Compared with standard medication, acupuncture were more efficacious in reducing NIH-CPSI total score (WMD: 3.36, 95% CI: 1.27-5.45), also showed significant greater pain relief (WMD: 2.36, 95% CI: 1.67-3.06), marginal advantage in improving QOL (WMD: 0.98, 95% CI: 0.12-1.83) but no difference in reducing urinary symptom (WMD: -0.03, 95% CI: -1.30 to 1.24). Four acupuncture sessions were the minimum "dose" to reach clinical efficacy, and prolonged acupuncture sessions continuously improved urinary symptoms and QOL. The majority of acupoint selection strategies were based on the combination of any three acupoints from CV3, CV4, BL32, SP6, and SP9.

Conclusions

Acupuncture has promising efficacy for patients with CP/CPPS, especially category IIIB, in aspects of relieving pain and urinary symptoms and improving the QOL. Acupuncture may serve as a standard treatment option when available, and a tailored comprehensive treatment strategy for CP/CPPS is the future trend.

Therapeutic Efficacy and the Impact of the "Dose" Effect of Acupuncture to Treat Sciatica: A Randomized Controlled Pilot Study

Purpose

To investigate the required sample size for and feasibility of a full-scale randomized controlled trial examining the impact of the “dose” effect of acupuncture in treating sciatica.

Patients and methods

Fifty-seven patients with sciatica, aged 35–70 years, were recruited and screened. Thirty-one participants were randomly assigned to receive “low-dose” manual acupuncture (MAL) (n= 15) or “high-dose” manual acupuncture (MAH) (n=16). The acupuncture treatment was administered twice weekly for 4 weeks. The primary outcome was the visual analog scale (VAS) score at baseline and after 4 weeks of acupuncture treatment. Secondary outcomes included the Roland Disability Questionnaire for Sciatica (RDQS), the Sciatica Bothersomeness Index (SBI), and the World Health Organization Quality of Life in the Brief Edition (WHOQOL-BREF) scores at baseline and after 4 weeks of acupuncture treatment.

Results

Thirty patients completed the study. For all patients, acupuncture achieved significant improvement in the VAS (5.48±2.0, p<0.001), RDQS (3.18±2.83, p=0.004), and SBI (2.85±3.23, p=0.008) scores, but not in the WHOQOL-BREF scores. In the between-group analysis, the assessed scales showed no significant differences between the MAL and MAH groups. However, based on the level of chronicity, the MAH group demonstrated greater improvement in the outcomes and a significant benefit in the physical subscale of the WHOQOL-BREF (p<0.05).

Conclusion

Results of this pilot study indicate that acupuncture is safe and may effectively relieve symptoms and disability in patients with non-acute sciatica. MAL was as effective as MAH in treating sciatica. A subsequent trial with a larger sample size (estimated at n=96) is required to confirm whether patients with a high level of chronicity would benefit from MAH treatment.

Acupuncture for Depression: A Systematic Review and Meta-Analysis

Background: Depression is commonly treated with anti-depressant medication and/or psychological interventions. Patients with depression are common users of complementary therapies, such as acupuncture, either as a replacement for, or adjunct to, their conventional treatments. This systematic review and meta-analysis examined the effectiveness of acupuncture in major depressive disorder. Methods: A search of English (Medline, PsychINFO, Google Scholar, and CINAL), Chinese (China National Knowledge Infrastructure Database (CNKI) and Wanfang Database), and Korean databases was undertaken from 1980 to November 2018 for clinical trials using manual, electro, or laser acupuncture. Results: Twenty-nine studies including 2268 participants were eligible and included in the meta-analysis. Twenty-two trials were undertaken in China and seven outside of China. Acupuncture showed clinically significant reductions in the severity of depression compared to usual care (Hedges (g) = 0.41, 95% confidence interval (CI) 0.18 to 0.63), sham acupuncture (g = 0.55, 95% CI 0.31 to 0.79), and as an adjunct to anti-depressant medication (g = 0.84, 95% CI 0.61 to 1.07). A significant correlation between an increase in the number of acupuncture treatments delivered and reduction in the severity of depression (p = 0.015) was found. Limitations: The majority of the included trials were at a high risk of bias for performance blinding. The applicability of findings in Chinese populations to other populations is unclear, due to the use of a higher treatment frequency and number of treatments in China. The majority of trials did not report any post-trial follow-up and safety reporting was poor. Conclusions: Acupuncture may be a suitable adjunct to usual care and standard anti-depressant medication.

The confirmation of treatment effects in Japanese acupuncture

BACKGROUND

Japanese acupuncture is gaining international recognition. However, previous research has failed to comprehensively describe the characteristics of Japanese acupuncture by not investigating it within the Japanese clinical environment. This qualitative ethnographic study aimed to identify unique and routine elements of Japanese acupuncture, describe these in detail and examine how they related to treatment principles.

METHODS

Between August 2012 and December 2016, ethnographic fieldwork was conducted in Japan. Participants were recruited by chain referral and emergent sampling. Data were collected through participant observation and interviews as well as by analyzing documents. A total of 38 participants were recruited. A total of 22 agreed to clinical observation; 221 treatments were observed with 172 patients. Seventeen participants consented to participate in formal interviews and 28 to informal interviews. Thematic analysis was used to evaluate data.

RESULTS

That practitioners tended to confirm perceived effects of interventions during treatment, was a major theme interpreted from the data. Confirmation was performed continually throughout treatment and at three different levels of timing and anatomical areas (micro, meso and macro). Many markers signified treatment effects which were in general, perceived by observing and/or palpating body tissue. Belief in the instantaneous effects of treatment and the value of effect through technique exemplify the philosophical foundations of confirmation. Continually monitoring treatment results at a range of time and body location increments is an important element of Japanese acupuncture.

CONCLUSION

This effect confirmation practice model promotes a system of constant feedback gained by repeated intervention and confirmation. This may be a unique feature of Japanese acupuncture.

Acupuncture and Related Therapies for Treatment of Postoperative Ileus in Colorectal Cancer: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Delays in recovery of intestinal function following abdominal surgery are associated with longer hospital stays, increased postoperative complications, and higher costs to the health care system. Studies of acupuncture for postoperative ileus and other postoperative issues have reported improvements. This systematic review and meta-analysis aimed to assess whether acupuncture assisted recovery following surgery for colorectal cancer (CRC). Randomized controlled trials (RCTs) were identified from major English and Chinese language biomedical databases. Participants (aged 18 years plus) had received surgical resection for CRC. 22 studies (1,628 participants) were included. Five were sham-controlled. Outcomes included gastrointestinal function recovery (21 studies), recovery of urinary function (1 study), postoperative abdominal distension (3 studies), and quality of life (1 study). Meta-analyses found significant reductions in time to first bowel sounds, first flatus, and first defecation in both the sham-controlled and nonblinded studies. These results suggested that the addition of acupuncture following CRC surgery improved recovery of gastrointestinal function based on four blinded good quality RCTs (281 participants) and 17 nonblinded lower quality RCTs (1,265 participants). The best available evidence was for interventions that included electroacupuncture at the point ST36 Zusanli and there is supporting evidence for other types of acupuncture therapies that involve stimulation of this point. This review is registered with the following: systematic review registration in PROSPERO: CRD42017079590.

Optimizing acupuncture treatment for dry eye syndrome: a systematic review

BACKGROUND

In a former meta-analysis review, acupuncture was considered a potentially effective treatment for dry eye syndrome (DES), but there were heterogeneities among the outcomes. We updated the meta-analysis and conducted subgroup analysis to reduce the heterogeneity and suggest the most effective acupuncture method based on clinical trials.

METHODS

We searched for randomized controlled trials (RCTs) in 10 databases (MEDLINE, EMBASE, CENTAL, AMED, SCOPUS, CNKI, Wangfang database, Oriental Medicine Advanced Searching Integrated System (OASIS), Koreamed, J-stage) and searched by hand to compare the effects of acupuncture and artificial tears (AT). We also conducted subgroup analysis by (1) method of intervention (acupuncture only or acupuncture plus AT), (2) intervention frequency (less than 3 times a week or more than 3 times a week), (3) period of treatment (less than 4 weeks or more than 4 weeks), and (4) acupoints (BL1, BL2, ST1, ST2, TE23, Ex-HN5). The Bucher method was used for subgroup comparisons.

RESULTS

Nineteen studies with 1126 patients were included. Significant improvements on the Schirmer test (weighted mean difference[WMD], 2.14; 95% confidence interval[CI], 0.93 to 3.34; p = 0.0005) and break up time (BUT) (WMD, 0.98; 95% CI, 0.79 to 1.18; p < 0.00001) were reported. In the subgroup analysis, acupuncture plus AT treatment had a weaker effect in BUT but a stronger effect on the Schirmer test and a better overall effect than acupuncture alone. For treatment duration, treatment longer than 1 month was more effective than shorter treatment. With regard to treatment frequency, treatment less than three times a week was more effective than more frequent treatment. In the acupoint analysis, acupuncture treatment including the BL2 and ST1 acupoints was less effective than treatment that did not include them. None of those factors reduced the heterogeneity.

CONCLUSIONS

Acupuncture was more effective than AT in treating DES but showed high heterogeneity. Intervention differences did not influence the heterogeneity.

Contact Tools in Japanese Acupuncture: An Ethnography of Acupuncture Practitioners in Japan

This study aimed to identify procedural elements of Japanese acupuncture, describe these elements in detail, and explain them in terms of the key thematic category of treatment principles. Between August 2012 and December 2016, ethnographic fieldwork was conducted in Japan. In total, 38 participants were recruited by chain referral and emergent sampling. Data was collected through participant observation, interviews, and by analyzing documents. A total of 22 participants agreed to clinical observation; 221 treatments were observed with 172 patients. Seventeen consented to formal interviews and 28 to informal interviews. Thematic analysis was used to critically evaluate data. One especially interesting theme was interpreted from the data: a variety of contact tools were applied in treatment and these were manipulated by adjusting elements of form, speed, repetition, and pressure. Tapping, holding, pressing/pushing, and stroking were the most important ways contact tools were used on patients. Contact tools are noninvasive, painless, can be applied in almost any environment, and may be easily accepted by patients worldwide. Contact tool theory and practice may be successfully integrated into acupuncture curricula outside of Japan, used to inform clinical trials, and contribute to an expanded repertoire of methods for practitioners to benefit individual patients in international contexts.

Beliefs and values in Japanese acupuncture: an ethnography of Japanese trained acupuncture practitioners in Japan

BACKGROUND

Japanese acupuncture is gaining international recognition. However, previous research has failed to comprehensively describe the characteristics of Japanese acupuncture by not investigating it within the Japanese clinical environment. This study aimed to identify unique and routine elements of Japanese acupuncture, describe these elements in detail, and examine how the current beliefs and attitudes of Japanese acupuncture practitioners related to philosophical concepts in their practice.

METHODS

Between August 2012 and December 2016, ethnographic fieldwork was conducted in Japan. Japanese trained acupuncture practitioners were recruited by chain referral and emergent sampling. Data were collected through participant observation, interviews, and by analyzing documents. Thematic analysis was used to critically evaluate the data.

RESULTS

Thirty-eight participants were recruited. Of these participants, 22 agreed to clinical observation; 221 treatments were observed with 172 patients. Additionally, 17 participants consented to participate in formal semistructured interviews and 28 to informal unstructured interviews (fieldwork discussion). Besides "knowledge," "beliefs and values" was a major theme interpreted from the data. Subthemes-including Zen Buddhism, effect through technique, instant effects of treatment, anatomical areas of significance, resolution of abnormalities, minimal stimulation, and patient comfort and customer service-were identified.

CONCLUSION

Beliefs and values are an underrepresented, yet extremely important aspect of philosophical concepts influencing acupuncture practice in Japan. Uniquely Japanese beliefs and values that do not rely on a commitment to any spiritual or religious affiliations or proprietary knowledge of traditional or biomedicine may be successfully exported from Japan to advance acupuncture education, research and practice in international contexts.

Reliability of the NICMAN Scale: An Instrument to Assess the Quality of Acupuncture Administered in Clinical Trials

BACKGROUND

The aim of this study was to examine the reliability of a scale to assess the methodological quality of acupuncture administered in clinical research.

METHODS

We invited 36 acupuncture researchers and postgraduate students to participate in the study. Firstly, participants rated two articles using the scale. Following this initial stage, modifications were made to scale items and the exercise was repeated. Interrater reliability was assessed for individual items using the Fleiss kappa statistic, whilst the overall scale used the intraclass correlation coefficient statistic. A threshold agreement of ≥0.61 was acceptable.

RESULTS

We received 26 responses and a 72% response rate. The first phase of testing found moderate reliability with intraclass correlation coefficients of 0.46 and 0.55 for the articles. The interrater reliability of the scales varied between and within the researchers (0.35, 0.60) and was more consistent with the postgraduate students (0.54, 0.54). Five items on the scale scored below the threshold and were revised for further testing. In this phase the intraclass correlation coefficient demonstrated variability between articles but improved to achieve reliability above the agreed threshold.

CONCLUSION

This study provides evidence of the reliability of the NICMAN scale although improvements to a small number of items remain.

Treating primary dysmenorrhoea with acupuncture: a narrative review of the relationship between acupuncture 'dose' and menstrual pain outcomes

OBJECTIVE

A number of randomised controlled trials have been performed to determine the effectiveness or efficacy of acupuncture in primary dysmenorrhoea. The objective of this review was to explore the relationship between the 'dose' of the acupuncture intervention and menstrual pain outcomes.

METHODS

Eight databases were systematically searched for trials examining penetrating body acupuncture for primary dysmenorrhoea published in English up to September 2015. Dose components for each trial were extracted, assessed by the two authors and categorised by neurophysiological dose (number of needles, retention time and mode of stimulation), cumulative dose (total number and frequency of treatments), needle location and treatment timing.

RESULTS

Eleven trials were included. Components of acupuncture dose were well reported across all trials. The relationship between needle location and menstrual pain demonstrated conflicting results. Treatment before the menses appeared to produce greater reductions in pain than treatment starting at the onset of menses. A single needle during menses may provide greater pain reduction compared to multiple needles. Conversely, multiple needles before menses were superior to a single needle. Electroacupuncture may provide more rapid pain reduction compared to manual acupuncture but may not have a significantly different effect on overall menstrual pain.

CONCLUSIONS

There appear to be relationships between treatment timing and mode of needle stimulation, and menstrual pain outcomes. Needle location, number of needles used and frequency of treatment show clear dose-response relationships with menstrual pain outcomes. Current research is insufficient to make definitive clinical recommendations regarding optimum dose parameters for treating primary dysmenorrhoea.

TCM Pattern Questionnaire for Lateral Elbow Pain: Development of an Instrument via a Delphi Process

Individualized acupuncture treatment has been practiced for pain therapy. This study used acupuncture treatment for lateral elbow pain (LEP) as an example to study the diagnostic practice of individualized acupuncture treatment. A provisional version of LEP pattern questionnaire was developed based on a recent systematic review on TCM pattern diagnosis for LEP. A Delphi panel of 33 clinical experts from seven different countries was formed, and the Delphi survey was conducted in Chinese and English language for two rounds. Consensus was achieved from all 26 panelists who responded to the second round on 243 items of the instrument, which included a 72-question-long questionnaire. The mean level of expert consensus on the items of the final questionnaire was 85%. Consensus was found on four TCM patterns that could underlie LEP, namely, the wind-cold-dampness pattern, the qi stagnation and blood stasis pattern, the dual deficiency of qi and blood pattern, and the retained dampness-heat pattern. A list of signs and symptoms indicating one of the four TCM patterns and a list of preferred treatment modalities for each pattern were also generated. Our instrument shows considerable content validity. Further validity and reliability studies are under way.

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.

Establishing key components of yoga interventions for reducing depression and anxiety, and improving well-being: a Delphi method study

BACKGROUND

Previous research suggests benefits of yoga in reducing depression and anxiety. However, common concerns in reviews of the research include lack of detail, rationale and consistency of approach of interventions used. Issues related to heterogeneity include amount, types and delivery of yoga interventions. This study aims to document consensus-based recommendations for consistency of yoga interventions for reducing depression and anxiety.

METHODS

The Delphi method was used to establish consensus from experienced yoga teachers. Thirty-three eligible teachers were invited to participate, from four different countries. Two rounds of an online survey were sent to participants. The first round sought initial views. The second round sought consensus on a summary of those views. Survey questions related to frequency and duration (dosage) of the yoga, approaches and techniques to be included or avoided, and training and experience for yoga teachers.

RESULTS

Twenty-four teachers agreed to participate. Eighteen completed the second round (n = 18). General consensus (>75% of participants in agreement) was achieved on parameters of practice (dosage): an average of 30 to 40 minutes, to be done 5 times per week, over a period of 6 weeks. Numerous recommendations for yoga techniques to include or avoid were collected in the first round. The second round produced a consensus statement on those recommendations. Breath regulation and postures were considered very important or essential for people with depression; and relaxation, breath regulation and meditation being very important or essential for people with anxiety. Other recommended components also achieved consensus. There was also general consensus that it is very important or essential for teachers to have a minimum of 500 training hours over 2 years, at least 2 years teaching experience, training in developing personalised yoga practices, training in yoga for mental health, and professional supervision or mentoring.

CONCLUSIONS

The Delphi process has achieved a consensus statement on the application of yoga for reducing anxiety and depression. This consensus provides a checklist for identification of commonalities and evaluation of past research. Future research can proceed to develop and evaluate consensus-based yoga intervention protocols for the reduction of anxiety and depression, and improvements in well-being.

Local and distant acupuncture points stimulation for chronic musculoskeletal pain: A systematic review on the comparative effects

One in four people suffers from chronic musculoskeletal pain (CMP). Acupuncture points stimulation is increasingly used for pain relief for CMP. Commonly, a combination of local and distant points is used. However, the difference between the effects of local and distant point stimulation is unknown. This systematic review aimed to determine if there was a difference in effects between stimulating local and distant points, and the combination of both when compared with either alone. English and Chinese electronic databases were searched to identify randomized controlled trials, where local or distant points were stimulated in adults with CMP. Pain intensity was the primary outcome measure. Nineteen were included in the qualitative analysis and 15 in the meta-analysis. Local and distant point stimulation was more effective than their respective controls in pain reduction immediately after treatment. Three studies directly compared the stimulation of local and distant points and found no significant difference between the two. No studies compared combined local and distant point stimulation with either alone. Subgroup analyses showed that, local tender point stimulation was more effective than local acupuncture points. Local and distant point stimulation induces similar degree of acupuncture analgesia. The benefit of combining local and distant point stimulation is unknown. However, subgroup analyses suggested that local tender points could be important in the treatment of CMP for short-term pain relief.

Faculty survey to assess research literacy and evidence-informed practice interest and support at Pacific College of Oriental Medicine

CONTEXT

Educating healthcare practitioners to understand, critically evaluate, and apply evidence to the clinical practice of complementary and alternative medicine has been an important initiative for the National Institutes of Health National Center for Complementary and Alternative Medicine.

OBJECTIVE

To determine the self-assessed research skills and interest of faculty at Pacific College of Oriental Medicine (New York campus) and their likely support of, and participatory interest in, an evidence-based medicine (EBM) training program.

DESIGN

The survey was administered in Survey Monkey. All questions were close-ended with 5-point Likert answers, except for one open-ended question at the end of the survey.

SETTING

One of three campuses of Pacific College of Oriental Medicine (PCOM), the largest Chinese medicine college in the United States.

PARTICIPANTS

102 faculty employed at PCOM.

RESULTS

The response rate was 88.7%. Responses illustrated a generally high degree of interest and support for research, EBM, and institutional participation in research activities. Faculty who responded to the open-ended question (19.6% of respondents) expressed concerns about the relevance of research to Chinese medicine and the possibility of co-option by biomedicine.

CONCLUSIONS

While faculty were overall supportive and interested in research and EBM, the results are consistent with the hypothesis that success of EBM training programs could be enhanced by soliciting and addressing faculty concerns and by being inclusive of approaches that honor the traditions of Chinese medicine and its own forms of clinical evidence.

Using a Delphi consensus process to develop an acupuncture treatment protocol by consensus for women undergoing Assisted Reproductive Technology (ART) treatment

Background

Assisted reproductive technologies (ART) are increasingly utilised for resolving difficulties conceiving. These technologies are expensive to both the public purse and the individual consumers. Acupuncture is widely used as an adjunct to ART with indications that it may assist reducing the time to conception and increasing live birth rates. Heterogeneity is high between treatment protocols.

The aim of this study was to examine what fertility acupuncturists consider key components of best practice acupuncture during an ART cycle, and to establish an acupuncture protocol by consensus.

Methods

Fifteen international acupuncturists with extensive experience treating women during ART interventions participated in 3 rounds of Delphi questionnaires. The first round focused on identifying the parameters of acupuncture treatment as adjunct to ART, the second round evaluated statements derived from the earlier round, and the third evaluated specific parameters for a proposed trial protocol. Consensus was defined as greater than 80% agreement.

Results

Significant agreement was achieved on the parameters of best practice acupuncture, including an acupuncture protocol suitable for future research. Study participants confirmed the importance of needling aspects relating to the dose of acupuncture, the therapeutic relationship, tailoring treatment to the individual, and the role of co-interventions. From two rounds of the Delphi a consensus was achieved on seven treatment parameters for the design of the acupuncture treatment to be used in a clinical trial of acupuncture as an adjunct to ART. The treatment protocol includes the use of the traditional Chinese medicine acupuncture, use of manual acupuncture, a first treatment administered between day 6–8 of the stimulated ART cycle which is individualised to the participant, two treatments will be administered on the day of embryo transfer, and will include points SP8, SP10, LR3, ST29, CV4, and post transfer include: GV20, KD3, ST36, SP6, and PC6. Auricular points Shenmen and Zigong will be used. Practitioner intent or yi will be addressed in the treatment protocol.

Conclusions

Despite a lack of homogeneity in the research and clinical literature on ART and acupuncture, a consensus amongst experts on key components of a best practice treatment protocol was possible. Such consensus offers guidance for further research.

A new method for quantifying the needling component of acupuncture treatments

OBJECTIVES

The highly variable nature of acupuncture needling creates challenges to systematic research. The goal of this study was to test the feasibility of quantifying acupuncture needle manipulation using motion and force measurements. It was hypothesised that distinct needling styles and techniques would produce different needle motion and force patterns that could be quantified and differentiated from each other.

METHODS

A new needling sensor tool (Acusensor) was used to record needling in real time as performed by six New England School of Acupuncture staff from the 'Chinese acupuncture' (style 1) and 'Japanese acupuncture' (style 2) programmes (three from each). Each faculty expert needled 12 points (6 bilateral locations) in 12 healthy human subjects using tonification (technique 1) and dispersal (technique 2). Parameters calculated from the raw needling data were displacement amplitude, displacement frequency, rotation amplitude, rotation frequency, force amplitude and torque amplitude.

RESULTS

Data analysis revealed significant differences in the amplitude of displacement and rotation between needling performed by staff from two different acupuncture styles. Significant overall differences in the frequency of displacement between techniques 1 and 2 that were not dependent of the style of acupuncture being performed were also found. The relationships between displacement and rotation frequencies, as well as between displacement and force amplitudes showed considerable variability across individual acupuncturists and subjects.

CONCLUSIONS

Needling motion and force parameters can be quantified in a treatment-like setting. Needling data can subsequently be analysed, providing an objective method for characterising needling in basic and clinical acupuncture research.
