Zhong Yi acupuncture and low-back pain: traditional Chinese medical acupuncture differential diagnoses and treatments for chronic lumbar pain

Comparative efficacy of acupuncture, venesection, and physical therapy on chronic low back pain outcomes: a randomized clinical trial

Objective

Chronic low back pain (CLBP) imposes considerable financial and social burden with poor response to medical and surgical treatments. Alternatively, acupuncture and venesection(Fasd) are traditionally used to alleviate nociceptive and musculoskeletal pains. This study aimed to evaluate the effectiveness and the safety of acupuncture and venesection on CLBP and patient functionality.

Methods

The current study was a single-blinded, randomized clinical trial with balanced allocation, conducted in the Department of Physical Medicine & Rehabilitation Medicine, in 2022. One hundred five CLBP patients who had no back pain-attributable structural or major diseases were randomly allocated into three parallel arms and received either physical therapy (PTG), acupuncture (APG), or venesection (VSG). Pain severity and functional aspects were evaluated using the visual analogue scale (VAS) and Oswestry disability index (ODI) during the study. VAS and ODI scores were defined as the primary outcomes.

Results

Ninety-five patients were reviewed in the final analysis (PTG=33, APG=30, VSG=31). Demographic data showed equal group distribution. Statistical analysis showed all procedures had reduced VAS score immediately after the first session, after the last session, and after follow-up; however, APG and VSG values were significantly lower (P<0.05). Pain reduction results in follow-up period were more sustainable in APG and VSG as compared to PTG (P<0.01). ODI results revealed global improvement after the last session of the treatment in all groups, while APG had more significant results (P<0.05). During the follow-up period, ODI still tended to decrease in VSG, non-significantly increased in APG, and significantly increased in PTG. Only two patients reported fainting after receiving venesection.

Conclusion

Considering the pain and functional scores, both acupuncture and venesection can reproduce reliable results. Acupuncture and venesection both have sustained effects on pain and daily function of the patients even after treatment termination, while physical therapy had more relapse in pain and functional limitations.

The strategies outlined in this review are paramount to supporting breast cancer survivors' quality of life.

Criteria for the selection, evaluation and application of traditional knowledge in contemporary health practice, education, research and policy: A systematic review

BACKGROUND

Traditional and complementary medicine (T&CM) is highly utilised and draws on traditional knowledge (TK) as evidence, raising a need to explore how TK is currently used.

OBJECTIVES

Examine criteria used to select, evaluate and apply TK in contemporary health contexts.

METHODS

Systematic search utilising academic databases (AMED, CINAHL, MEDLINE, EMBASE, SSCI, ProQuest Dissertations Theses Global), Trip clinical database and Google search engine. Citations and reference lists of included articles were searched. Reported use of TK in contemporary settings was mapped against a modified 'Exploration-Preparation-Implementation-Sustainment' (EPIS) implementation framework.

RESULTS

From the 54 included articles, EPIS mapping found TK is primarily used in the Exploration phase of implementation (n = 54), with little reporting on Preparation (n = 16), Implementation process (n = 6) or Sustainment (n = 4) of TK implementation. Criteria used in selection, evaluation and application of TK commonly involved validation with other scientific/traditional evidence sources, or assessment of factors influencing knowledge translation.

DISCUSSION

One of the difficulties in validation of TK (as a co-opted treatment) against other evidence sources is comparing like with like as TK often takes a holistic approach. This complicates further planning and evaluation of implementation.

CONCLUSION

This review identifies important criteria for evaluating current and potential contemporary use of TK, identifying gaps in research and practice for finding, appraising and applying relevant TK studies for clinical care.

Experimental Studies of Inter-Rater Agreement in Traditional Chinese Medicine: A Systematic Review

Objectives: It has been recommended that clinical trials of Traditional Chinese Medicine (TCM) would be more ecologically valid if its characteristic mode of diagnostic reasoning were integrated into their design. In that context, however, it is also widely held that demonstrating a high level of agreement on initial TCM diagnoses is necessary for the replicability that the biomedical paradigm requires for the conclusions from such trials. Our aim was to review, summarize, and critique quantitative experimental studies of inter-rater agreement in TCM, and some of their underlying assumptions. Design: Systematic electronic searches were conducted for articles that reported a quantitative measure of inter-rater agreement across a number of rating choices based on examinations of human subjects in person by TCM practitioners, and published in English language peer-reviewed journals. Publications in languages other than English were not included, nor those appearing in other than peer-reviewed journals. Predefined categories of information were extracted from full texts by two investigators working independently. Each article was scored for methodological quality. Outcome measures: Design features across all studies and levels of inter-rater agreement across studies that reported the same type of outcome statistic were compared. Results: Twenty-one articles met inclusion criteria. Fourteen assessed inter-rater agreement on TCM diagnoses, two on diagnostic signs found upon traditional TCM examination, and five on novel rating schemes derived from TCM theory and practice. Raters were students of TCM colleges or graduates of TCM training programs with 3 or more years experience and licensure. Type of outcome statistic varied. Mean rates of pairwise agreement averaged 57% (median 65, range 19-96) across the 9 studies reporting them. Mean Cohen's kappa averaged 0.34 (median 0.34, range 0.07-0.59) across the seven studies reporting them. Meta-analysis was not possible due to variations in study design and outcome statistics. High risks of bias and confounding, and deficits in statistical reporting were common. Conclusions: With a few exceptions, the levels of agreement were low to moderate. Most studies had significant deficits of both methodology and reporting. Results overall suggest a few design features that might contribute to higher levels of agreement. These should be studied further with better experimental controls and more thorough reporting of outcomes. In addition, methods of complex systems analysis should be explored to more adequately model the relationship between clinical outcomes, and the series of diagnoses and treatments that are the norm in actual TCM practice.

Treating the patient not the symptoms: Acupuncture to improve overall health - Evidence, acceptance and strategies

Documented mechanisms of acupuncture suggest the possibility of whole body effects in addition to local and regional effects. Traditional theories of acupuncture predict whole body effects. Does this permit the possibility of applying treatment to target overall health improvement of the patient rather than the symptom? After introducing the term 'health improvement' this paper explores situations where it might be advantageous to do this, giving examples of how health authorities in some countries have proposed broader treatment approaches that focus on health improvement. It also discusses cases where acupuncture has been recommended as a treatment method in a number of these proposals and gives some clinical examples of this kind of whole body 'health improvement' targeted treatment effects. Given that health authorities have already recognised this potential for the application of acupuncture the author then explores evidence of more whole-body 'health improvement' effects from systematic reviews and examples of health experts recommending acupuncture to take advantage of them. Research strategies and foci are then proposed and explored to develop this evidence. What are the best treatment approaches to create these effects? By what mechanisms can 'health improvement' be produced? How can one measure these effects? It is likely that treatments based on 'pattern identification' (PI) may provide the best strategies for producing 'health improvement', thus PI-based acupuncture treatments are likely to be the best strategy for clinical research investigating these effects.

SEED: the six excesses (Liu Yin) evaluation and diagnosis scale

Background

Infections such as common colds, influenza, acute upper respiratory infections, bacterial gastroenteritis, and urinary tract infections are usually diagnosed according to patients’ signs and symptoms. This study aims to develop a scale for the diagnosis of infectious diseases based on the six excesses (Liu Yin) etiological theory of Chinese medicine (CM) by the Delphi method.

Methods

A total of 200 CM-guided diagnostic items measuring signs and symptoms for infectious diseases were compiled from CM literature archives from the Han to Ming dynasties, CM textbooks in both China and Taiwan, and journal articles from the China Knowledge Resource Integrated Database. The items were based on infections and the six excesses (Liu Yin) etiological theory, i.e., Feng Xie (wind excess), Han Xie (coldness excess), Shu Xie (summer heat excess), Shi Xie (dampness excess), Zao Xie (dryness excess), and Huo Xie (fire excess). The items were further classified into the six excess syndromes and reviewed via a Delphi process to reach consensus among CM experts.

Results

In total, 178 items with a mean or median rating of 7 or above on a scale of 1–9 from a panel of 32 experts were retained. The numbers of diagnostic items in the categories of Feng (wind), Han (coldness), Shu (summer heat), Shi (dampness), Zao (dryness), and Huo (fire) syndromes were 15, 22, 25, 37, 17, and 62, respectively.

Conclusions

A CM-based six excesses (Liu Yin) evaluation and diagnosis (SEED) scale was developed for the evaluation and diagnosis of infectious diseases based only on signs and symptoms.

Designing clinical studies that take into account traditional East Asian medicine's systems and methods - with focus on pattern identification

This article is based on two presentations held at Chinese medicine conference in Rothenburg (2013), Germany and at the 19th Anniversary of Korean Institute of Oriental Medicine (KIOM) International Symposium of Current Research Trends in Traditional Medicine - Pattern of Identification (2013). In designing clinical studies, it is a research question that leads to appropriate study design. However, they are mostly diagnostic procedures and techniques that are the key points to reflect the application of systems and methods in all forms of medicine - traditional East Asian medicine (TEAM) is no exception. The challenges within TEAM based on research reflect in different systems of medicine/theories such as traditional Japanese acupuncture, traditional Korean acupuncture and traditional Chinese acupuncture. This diversity of medical systems and methods applied in East Asia seems to have been fruitful within the different countries and traditional medicines have found their places within the respective countries health systems. The existing diversity, from a clinician's point of view, may be viewed as a treasure when dealing with patients in the 'real world'. On the other hand, this diversity seems to challenge the scientific mind worldwide, especially when it comes to research. Hence, there is a gap between clinical practice and research.

Reliability of the Eight Guiding Principles and Syndrome Diagnosis in Chinese Medicine Diagnosis of Patients with Knee Osteoarthritis

Abstract Background: A Chinese medicine (CM) "Syndrome" or "pattern of disharmony" is a diagnostic subcategory of a disease/disorder or symptom, characterized by particular symptoms and signs, and indicative of the etiology and the state of pathogenesis at that point in time. In CM, treatment is aimed at addressing the disease/disorder and the underlying CM Syndrome. A few studies have assessed reliability of CM Syndrome diagnosis according to one of the major CM theories, Zang-Fu theory, but only 1 study has investigated the reliability of diagnosis according to a fundamental theory, that of the Eight Guiding Principles. Given that treatment follows diagnosis, if diagnosis is not reliable there will be lower confidence that optimal treatment is received. There have not yet been any reliability studies in osteoarthritis (OA). Little is known about the characteristics or Syndromes of OA with respect to the Eight Guiding Principles and Zang-Fu theory. Objectives: The objectives of this study were to characterize diagnostic subcategories of OA according to the Eight Guiding Principles and Zang-Fu theory and to investigate the inter-rater reliability of CM diagnosis according to these two theories. Methods: An inter-rater reliability study was conducted as a substudy of a clinical trial investigating the treatment of knee OA with Chinese herbal medicine. Two (2) experienced CM practitioners conducted a CM examination separately, within 2 hours of each other, of 40 participants. A CM assessment form was utilized to record the diagnostic data. Cohen's κ coefficient was used as a measure of reliability. Results: Results support the concept that knee OA is more likely a disease with characteristics of Interior, Deficiency, and Yin according to the Eight Guiding Principles. There was no clear agreement on CM Syndromes of knee OA according to Zang-Fu theory. The main Zang Organs involved were broadly agreed on; they were Kidney, Liver, and Spleen. Conclusions: Results lend some empirical evidence to support to the argument that OA of the knee is an Internal disease with the manifestations of Deficient symptoms according to CM theories. To establish if Syndrome diagnosis is reliable, more studies should be conducted for different clinical conditions.

Construction of a traditional Chinese medicine syndrome-specific outcome measure: the Kidney Deficiency Syndrome Questionnaire (KDSQ)

Background

Development of Traditional Chinese Medicine (TCM) syndrome-specific outcome measures is needed for the evaluation of TCM syndrome-specific therapies. We constructed a Kidney Deficiency Syndrome Questionnaire (KDSQ) for the evaluation of the common TCM syndromes Kidney-Yin Deficiency Syndrome (KDS-Yin) and Kidney-Yang Deficiency Syndrome (KDS-Yang) in middle-aged women with menopausal symptoms.

Methods

KDS-Yin and KDS-Yang were traditionally defined by expert opinion were validated by exploratory factor analysis (EFA) and structural equation modeling (SEM). Content validity was tested by EFA on a sample of 236 women from a seminar and SEM on another sample of 321 women from a postal survey. Other psychometric properties were tested on 292 women from the seminar at baseline and two systematically selected sub-samples: 54 who reported no changes in discomforts 11–12 days after the baseline and 31 who reported changes in discomforts 67–74 days after the baseline. All participants completed the KDSQ, the Greene Climacteric Scale and the standard 12-item Short Form Health Survey.

Results

The EFA and SEM established the measurement models of KDS-Yin and KDS-Yang supporting content validity of the KDSQ. Internal consistency was good (Cronbach’s Alpha >0.70). Construct validity was supported by theoretically-derived levels of correlation with the established external measures. Test–retest reliability was strong (ICC_agreement: KDS-Yin, 0.94; KDS-Yang, 0.93). The KDSQ was responsive to changes over time as tested by effect size and longitudinal validity.

Conclusions

The KDSQ was a valid and reliable measure for KDS-Yin and KDS-Yang in Hong Kong Chinese middle-aged women with menopausal symptoms.

An evidence-based validation of traditional Chinese medicine syndromes

OBJECTIVES

A standard description regarding the diagnosis of traditional Chinese medicine (TCM) syndromes based on validated evidence is needed for education, practice and evaluation of TCM syndrome-specific treatments. We studied whether an evidence-based four-step approach proposed for the validation of TCM syndromes could validate Kidney-Yin deficiency syndrome (KDS-Yin) and Kidney-Yang deficiency syndrome (KDS-Yang) in middle-aged women with menopausal symptoms.

METHODS

TCM classic and contemporary literature were reviewed for the symptoms and the domain changes of KDS-Yin and KDS-Yang. Factor analysis was used to explore whether these symptoms could be grouped according to their mutual relationships in a sample of women. Latent tree models were constructed based on the factor loadings and justifiability by the theory, and were tested by structural equation modelling on another sample of women.

RESULTS

The symptoms and domain changes were reviewed from the TCM literature. Exploratory factor analysis (EFA) identified symptom patterns on a sample of 236 women. Based on the findings and the TCM literature, latent tree models of KDS-Yin and KDS-Yang, showing their domain changes and domain symptoms, were constructed and could be confirmed by structural equation modelling on a sample of 323 women.

CONCLUSION

KDS-Yin and KDS-Yang in middle-aged women with menopausal symptoms were validated and the four-step approach may be used to validate TCM syndromes.

Different frequencies of acupuncture treatment for chronic low back pain: an assessor-blinded pilot randomised controlled trial

OBJECTIVES

To examine the feasibility of a main RCT to compare the effectiveness of two frequencies (2 versus 5 times/week) of acupuncture treatment for chronic low back pain (LBP).

METHODS

Participants (n=30) with chronic LBP were randomised into two groups to receive 10 acupuncture treatments: Low Frequency Group, 2 times/week for five weeks (n=15); High Frequency Group, 5 times/week for two weeks (n=15). The following outcomes were measured blindly at baseline, 2 weeks, 5 weeks, 3 months and 1 year: pain on a VAS, functional disability using the RMDQ, quality of life using the Measure Yourself Medical Outcome Profile (MYMOP-2), psychological impact with the Coping Strategies Questionnaire (CSQ) and Pain Locus of Control (PLC) questionnaire. Two objective outcomes, the Shuttle Walk Test (SWT) and Lateral Trunk Flexibility (LTF), were also measured.

RESULTS

The compliance rate was 100% for each group. Some of the measurements were shown to be sensitive (VAS, RMDQ, MYMOP-2 Wellbeing). 66-330 participants would be required for a fully powered non-inferiority trial. The groups were balanced at baseline for LBP and demographic characteristics. There were no significant differences between the groups in terms of any of the outcomes, at each follow-up time point. It was notable however that the clinically important improvement in terms of pain, functional disability, quality of life, and SWT in both groups was achieved within the first two weeks, which was maintained at one year follow-up.

CONCLUSIONS

It is feasible to conduct a main RCT, to compare different frequencies of acupuncture for LBP, using sensitive measurements. Also the trend for early clinically important improvement within a minimum of four measurements is worthy of further study.

Improvement of agreement in TCM diagnosis among TCM practitioners for persons with the conventional diagnosis of rheumatoid arthritis: effect of training

OBJECTIVE

To investigate whether a training process that focused on consensus on Traditional Chinese Medicine (TCM) diagnostic criteria will improve the agreement of TCM diagnosis on patients with rheumatoid arthritis (RA).

DESIGN

The design was a prospective survey.

SETTING

The study was conducted at the General Clinical Research Center, University of Maryland Hospital System, Baltimore, MD.

SUBJECTS

The participants were 42 patients with RA. PRACTITIONERS: The practitioners included 3 licensed acupuncturists with a minimum of 5 years' licensure and education in Chinese herbs.

METHODS

A training session of TCM diagnostic procedures was conducted with an open case discussion and "real time" practice. After the training, 3 TCM practitioners examined the same 42 patients with RA separately. Patients filled out a questionnaire to serve as the data for the "Inquiry" component while physical examinations, including observations of tongue and palpation of radial pulse, were conducted by the 3 practitioners. Each practitioner provided a TCM diagnosis based upon the examination results. These diagnoses were then examined with respect to the rate of agreement among the 3 practitioners.

RESULTS

The average agreement with respect to the TCM diagnoses among the 3 pairs of TCM practitioners was 73% (64.3%-85.7%). Statistically significant differences were found between this study and the two previous studies (p < 0.001).

CONCLUSIONS

After training focused on consensus on TCM diagnostic criteria, we found that these 3 same TCM practitioners who were used in phase II of the study produced a significantly higher agreement when compared to study phase I or phase II. Our study suggests that improved consensus on TCM diagnostic criteria results in increased agreement of diagnosis.

Interventions and Physician Characteristics in a Randomized Multicenter Trial of Acupuncture in Patients with Low-Back Pain

OBJECTIVE

Descriptions of the interventions used in acupuncture studies are often incomplete. The aim of this paper is to describe participating trial physicians and interventions in a randomised trial of acupuncture for low back pain.

DESIGN

Three-armed, randomized, controlled multicenter trial with 1-year follow-up. A total of 301 patients with low-back pain were randomized to 12 sessions of semistandardized acupuncture (at least six local and two distant points needled bilaterally from a selection of predefined points, but individual choice of additional body or ear acupuncture points possible), minimal acupuncture (superficial needling of at least 6 of 10 predefined, bilateral, distant nonacupuncture points), or a waiting list control (2 months no acupuncture followed by semistandardised acupuncture described above).

OUTCOME MEASURES

Participating trial physicians and interventions.

RESULTS

Forty-five (45) physicians specializing in acupuncture (mean age 44 +/- 7.8 years, 23 (51%) female) in 30 outpatient centers in Germany provided the interventions. The median duration of acupuncture training of trial physicians was 350 hours (range 140-2508). The most frequently reported Chinese diagnosis was Kidney deficiency (39%), followed by qi and Blood stagnation (24%), and bi syndrome (20%). The total number of needles used was 17.3 +/- 4.2 in the acupuncture group compared to 12.3 +/- 1.2 in the minimal acupuncture group. In total, 40 physicians (89%) stated that they would have treated patients similarly or in exactly the same way outside of the trial, whereas 5 (11%) stated that they would have treated patients differently.

CONCLUSIONS

For most trial physicians, the semistandardized acupuncture strategy used in this trial was an acceptable compromise for an efficacy study. However, a relevant minority of participating trial physicians stated that they would have treated patients differently outside of the trial.

Pain prevalence, experiences and management strategies among the elderly in taiwanese nursing homes

The purpose of this study was to explore pain prevalence, experiences, and self-care management strategies among elderly residents of nursing homes in Taiwan. Stratified random sampling was used to recruit participants (n=150). In these elderly nursing home residents, pain prevalence was 65.3% and the average number of pain sites was 3.24 (SD=2.59). The mean pain intensity was 3.86 (SD=1.90) and pain interference was 4.30 (SD=2.28). "Aching" was the word most commonly used (77.6%) to describe pain. Most participants (54.21%) took prescribed medications for dealing with pain; doctors were the main information source for this self-care strategy. Although participants reported severe bouts of pain, they used limited self-care pain management strategies. Since health care providers play an important role in helping the elderly to manage pain, the authors recommend training nursing home staff to perform regular pain assessments and providing current knowledge about pain assessment and management strategies.

Clinical Research on Acupuncture: Part 2. Controlled Clinical Trials, an Overview of Their Methods

There is almost universal agreement that the quality of clinical trials of acupuncture is poor. There is an urgent need to improve their quality. The author develops here a list of 45 criteria important in the design, implementation, and writing up of controlled clinical acupuncture trials. This list has been compiled after examining the quality assessment criteria used in meta-analyses and systematic reviews of acupuncture, general publications on clinical trial designs and methodological considerations specific to acupuncture trials. Each criterion is discussed with recommendations about use and implementation. Additionally, each criterion is discussed relative to their importance in three types of acupuncture trial, acupuncture versus sham acupuncture, acupuncture versus standard therapy and acupuncture versus no treatment or wait-list. It is hoped that this exploration and systematic presentation of the 45 criteria will contribute to improving the quality of clinical trials of acupuncture. Improved trial quality will lead to greater ease interpreting the results of trials, especially in systematic reviews.

Acupuncture for low back pain: traditional diagnosis and treatment of 148 patients in a clinical trial

AIMS

To assess patterns of diagnosis, including concordance, and treatment within a clinical trial of traditional acupuncture for low back pain.

SETTING

In a pragmatic randomised controlled clinical trial, 148 patients with low back pain, of between 4 weeks and 12 months duration, were randomised to the offer of individualised acupuncture and received up to 10 treatments.

METHODS

Standardised diagnosis and treatment records were completed by practitioners for 148 patients. The diagnosis was based on three pre-defined low back pain syndromes. For a subgroup of patients, one of the six practitioners then independently re-examined the patients, blind to the original diagnosis. The diagnostic inter-rater reliability was assessed in terms of percentage congruent classifications and Cohen's Kappa. Structured interviews of practitioners established further details about practice styles.

RESULTS

The most commonly diagnosed syndrome associated with low back pain was Qi and Blood Stagnation (88% of patients), followed by Kidney Deficiency (53%) and Bi Syndrome (28%), with more than one syndrome being identified for 65% of patients. For the subgroup examined twice, practitioner concordance was reasonable: between 47 and 80% of classifications were congruent, while Kappa values lay between 0 ("the same as chance") and 0.67 ("good"). Practitioners provided 1269 treatments in total, using 177 different acupuncture points. Most commonly used channels were Bladder and Gall Bladder, and the commonest points were BL-23 and the two lowest Huatuojiaji points. Auxiliary treatments were utilised by all practitioners to varying degrees.

CONCLUSIONS

Diagnostic concordance among practitioners was reasonable, and clear themes emerged for treatment. Further research is required to develop a flexible trial protocol with scope for individualised treatment.

One-shot percutaneous electrical nerve stimulation vs. transcutaneous electrical nerve stimulation for low back pain: comparison of therapeutic effects

OBJECTIVE

To investigate the therapeutic effects of one shot of low-frequency percutaneous electrical nerve stimulation one shot of transcutaneous electrical nerve stimulation in patients with low back pain.

DESIGN

In total, 133 low back pain patients were recruited for this randomized, control study. Group 1 patients received medication only. Group 2 patients received medication plus one shot of percutaneous electrical nerve stimulation. Group 3 patients received medication plus one shot of transcutaneous electrical nerve stimulation. Therapeutic effects were measured using a visual analog scale, body surface score, pain pressure threshold, and the Quebec Back Pain Disability Scale.

RESULTS

Immediately after one-shot treatment, the visual analog scale improved 1.53 units and the body surface score improved 3.06 units in the percutaneous electrical nerve stimulation group. In the transcutaneous electrical nerve stimulation group, the visual analog scale improved 1.50 units and the body surface score improved 3.98 units. The improvements did not differ between the two groups. There were no differences in improvement at 3 days or 1 wk after the treatment among the three groups.

CONCLUSIONS

Simple one-shot treatment with percutaneous electrical nerve stimulation or transcutaneous electrical nerve stimulation provided immediate pain relief for low back pain patients. One-shot transcutaneous electrical nerve stimulation treatment is recommended due to the rarity of side effects and its convenient application.

The diagnosis and treatment of patients with chronic low-back pain by traditional Chinese medical acupuncturists

The selection of appropriate treatments in clinical trials of acupuncture requires understanding how acupuncturists diagnose and treat specific conditions. We examined the Traditional Chinese Medical (TCM) diagnoses and treatments for patients with chronic low-back pain using two separate sets of treatment records. Information from more than 150 initial visits was available for analysis. A diagnosis of Qi and Blood Stagnation or Qi Stagnation was made for 85% of patients. A diagnosis of kidney deficiency (or one of its three subtypes) was made for 33%-51% of patients. Other specific diagnoses were made for less than 20% of the patients. An average of 12-13 needles was used in each treatment. Although more than 85 different acupoints were used in each data set, only 5 or 6 acupoints were used in more than 20 of the treatments in each data set. Only two of those acupoints (UB23, UB40) were the same for both sources of data. More than half of the patients received adjunctive treatments, including heat (36%-67%), and cupping (16%-21%). There was substantial variability in treatments among providers. Such diversity will make it challenging to select a single treatment that has wide applicability. We recommend that researchers attempt to develop a treatment that is considered credible by expert acupuncturists and has broad features characteristic of patterns of common clinical practice.

Variation in diagnosis and treatment of chronic low back pain by traditional Chinese medicine acupuncturists

OBJECTIVES

To assess interrater reliability of Traditional Chinese Medicine (TCM) diagnosis and treatment of chronic low back pain.

DESIGN

Under a Latin square design, six TCM acupuncturists evaluated the same six patients on the same day.

SETTING

Northwest Institute of Acupuncture and Oriental Medicine, Seattle, Washington.

INTERVENTIONS

Assessment only.

OUTCOME MEASURES

TCM diagnosis, acupoint prescriptions, auxiliary treatment recommendations.

RESULTS

Twenty diagnoses and 65 acupoints were used at least once. The diagnosis of Qi/Blood Stagnation with Kidney Deficiency and the acupoint UB23 were used for every patient by most acupuncturists. However, consistency across acupuncturists regarding diagnostic details and other acupoints was poor. No diagnoses, and only one acupoint, were used preferentially for a subgroup of patients. Some diagnoses and treatment recommendations were dependent more on the practitioner than on the patient. Fine-grained diagnoses and most acupoints were unrelated to either patient or practitioner.

CONCLUSIONS

TCM diagnoses and treatment recommendations for specific patients with chronic low back pain vary widely across practitioners. Acupuncture clinical trials using an individualized treatment arm may be difficult to replicate or evaluate because of low concordance among acupuncturists. Comparison of individualized treatment with a thoughtfully developed standardized approach is warranted to determine which, if either, is superior.

How traditional Chinese medicine acupuncturists would diagnose and treat chronic low back pain: results of a survey of licensed acupuncturists in Washington State

OBJECTIVES

This survey was undertaken to learn how Traditional Chinese Medicine acupuncturists' diagnose and treat patients with chronic low back pain in order to develop a standardized treatment for a clinical trial of that condition.

DESIGN

We surveyed a randomly selected group of 56 acupuncturists in Washington State, USA about styles of acupuncture they used for treating chronic low back pain, diagnoses made, and key features of treatment for this condition.

RESULTS

While substantial variability existed among practitioners, there was agreement on several broad features of treatment including: the use of local and distal acupuncture points (86% of practitioners), the use of acupuncture points on the meridians traversing the back (especially the UB meridian, 90%) the use of acupoints determined by palpation (82%), the importance of eliciting de qi (60%), and of providing up to eight treatments for achieving therapeutic results (79%).

CONCLUSION

The use of practitioner surveys can enhance the systematic development of acupuncture treatment protocols and should be part of this process in future clinical trials of common conditions.

Traditional Chinese medicine syndromes in women with frequently recurring cystitis: frequencies of syndromes and symptoms

BACKGROUND

Frequently recurrent acute cystitis in adult women is common in Western medicine. In prophylactic treatment, women are treated between attacks of acute cystitis to prevent recurrences. A recent study has shown that acupuncture seems effective for prophylaxis.

OBJECTIVES

To describe the frequency of traditional Chinese medicine (TCM) syndromes found in females vulnerable to recurrent cystitis, and which symptoms most often form the basis for TCM diagnoses made in this condition.

METHODS

A descriptive study based on TCM diagnostic methods as used by experienced acupuncturists, and a questionnaire of symptoms used in TCM diagnostics.

RESULTS

Of 61 women with frequently recurring cystitis, 90% were diagnosed as having either a Spleen/Kidney yang xu/qi xu (54%), or a Liver qi stagnation (36%). Only 10% fell in other diagnostic groups. Of all symptoms noted, only three differed in frequency between the two main diagnostic groups: feeling cold (29/33 vs. 13/22, P<0.05), feeling tired (25/33 vs. 4/22, P<0.001), and having a preference for sweets (10/33 vs. 2/22, P<0.05).

CONCLUSION

Our findings have implications for TCM-based diagnostic work in females with recurrent cystitis, and also indicate that recurrent cystitis may be used as a case for further TCM research.
