  • Do the effects of acupuncture vary between Acupuncturists? Analysis of the Acupuncture Trialists' Collaboration individual patient data meta-analysis.
    Acupuncture in medicine : journal of the British Medical Acupuncture Society, 2020
    Co-Authors: Andrew J Vickers, George Lewith, Karen J. Sherman, Hugh Macpherson, Nadine E Foster, Claudia M Witt, Emily A Vertosick, Dominik Irnich, Klaus Linde
    Abstract:

    The degree to which the effects of acupuncture treatment vary between Acupuncturists is unknown. We used a large individual patient dataset of trials of acupuncture for chronic pain to assess practitioner heterogeneity. Individual patient data linked to identifiable Acupuncturists were drawn from a dataset of 39 high-quality trials of acupuncture, where the comparators were either sham acupuncture or non-acupuncture controls, such as standard care or waitlist. Heterogeneity among Acupuncturists was assessed by meta-analysis. A total of 1206 Acupuncturists in 13 trials were included. Statistically significant heterogeneity was found in trials with sham-control groups (p < 0.0001) and non-acupuncture control groups (p <0.0001). However, the degree of heterogeneity was very small, with the observed distribution of treatment effects virtually overlapping that expected by chance. For instance, for non-acupuncture-controlled trials, the proportion of Acupuncturists with effect sizes half a standard deviation greater or less than average was expected to be 34%, but was observed to be 37%. A limitation is that the trials included a relatively limited range of Acupuncturists, mainly physician-Acupuncturists. Although differences in effects between Acupuncturists were greater than expected by chance, the degree of variation was small. This suggests that most chronic pain patients in clinical practice would have similar results to those reported in high-quality trials; comparably, we did not find evidence to suggest that greater standardization of acupuncture practice would improve outcomes. Further research needs to be conducted exploring variability using a sample of Acupuncturists with a broader range of practice styles, training and experience.

  • The diagnosis and treatment of chronic back pain by Acupuncturists, chiropractors, and massage therapists.
    The Clinical journal of pain, 2006
    Co-Authors: Karen J. Sherman, Daniel C. Cherkin, Janet H. Erro, Andrea Hrbek, Richard A. Deyo, Roger B. Davis, David Eisenberg
    Abstract:

    Objectives: To describe the diagnostic and therapeutic content of visits for chronic back pain to Acupuncturists, chiropractors, and massage therapists. Methods: Randomly selected Acupuncturists, chiropractors, and massage therapists in two states were surveyed, and then eligible providers collected data on consecutive patient visits. The authors analyzed information on diagnosis, treatment, and self-care recommendations for chronic back pain patients collected during consecutive patient visits to these complementary and alternative medicine (CAM) providers. Results: Back pain was the most common reason for visits to each of these providers, with chronic back pain representing about 10% of visits to Acupuncturists, 20% of visits to chiropractors, and 12% of visits to massage therapists. Diagnosis by Acupuncturists included traditional questioning and inspecting the patient as well as pulse and tongue assessment and palpation of the acupuncture meridians. Treatments usually included acupuncture needling, heat of some sort, and other modalities, such as East Asian massage, herbs, and/or cupping (application of suction cups to the skin). Lifestyle recommendations were common, particularly exercise and dietary counseling. Visits to chiropractors usually included spinal and muscle/soft tissue examinations and spinal manipulation. Soft tissue techniques (eg, "active release"), stretch or strength training, and home exercise recommendations were much less common. Massage therapists usually performed a tissue assessment and commonly assessed range of motion. They emphasized Swedish, deep tissue, and trigger point massage techniques and usually made self-care recommendations, particularly increased water intake, hot/cold therapy, exercise, and body awareness. Conclusion: Information on the care patients routinely receive from CAM providers will help physicians better understand these increasingly popular forms of care.

  • The practice of acupuncture: Who are the providers and what do they do?

    Abstract:

    PURPOSE This study provides basic information about the training and practices of licensed Acupuncturists. METHODS Randomly selected licensed Acupuncturists in Massachusetts and Wash- ington state were interviewed and asked to record information on 20 consecutive patient visits. RESULTS Most Acupuncturists in both states had 3 or 4 years of academic acu- puncture training and had received additional "postgraduate" training as well. Acupuncturists treated a wide range of conditions, including musculoskeletal problems (usually back, neck, and shoulder) (33% in Massachusetts and 47% in Washington), general body symptoms (12% and 9%, respectively) such as fatigue, neurological problems (10% and 12%, respectively) (eg, headaches), and psy- chological complaints (10% and 8%, respectively) (especially anxiety and depres- sion). Traditional Chinese medicine (TCM) was the predominant style of acupunc- ture used in both states (79% and 86%, respectively). Most visits included a tra- ditional diagnostic assessment (more than 99%), regular body acupuncture (95% and 93%, respectively), and additional treatment modalities (79% and 77%, respectively). These included heat and lifestyle advice (66% and 65%, respec- tively), most commonly dietary advice and exercise recommendations. Chinese herbs were used in about one third of visits. Although most patients self-referred to acupuncture, about one half received concomitant care from a physician. Acu- puncturists rarely communicated with the physicians of their patients who were providing care for the same problem. CONCLUSIONS This study contributes new information about Acupuncturists and the care they provide that should be useful to clinicians interested in becoming more knowledgeable about complementary or alternative medical therapies avail- able to their patients.

  • A comparison of physician and nonphysician acupuncture treatment for chronic low back pain.
    The Clinical journal of pain, 2005
    Co-Authors: Donna Kalauokalani, Daniel C. Cherkin, Karen J. Sherman
    Abstract:

    Background Although up to a third of the 10,000 Acupuncturists in the United States are medical doctors, little is known about the acupuncture techniques they use or how their practices compare with those of nonphysician licensed Acupuncturists. This is the first study providing descriptive data on physician acupuncture and comparison to nonphysician acupuncture. Purpose This study describes how a random sample of physician Acupuncturists in the United States diagnose and treat chronic low back pain and contrasts their practices with those of nonphysician licensed Acupuncturists. Methods A total of 464 questionnaires were mailed to physician Acupuncturists randomly sampled from 3 sources: web-based Yellow Pages, American Academy of Medical Acupuncturists (AAMA) membership, and Pain Clinics associated with American College of Graduate Medical Education-approved fellowship programs. Responses (n=137, 30%) were analyzed using descriptive statistics. The results of this survey were compared with data published from a similar survey of nonphysician licensed Acupuncturists in Washington State. Results Physicians who perform acupuncture use a mixture of styles and emphasize neuroanatomic approaches to needle placement. Most physicians received training in French Energetic acupuncture. In contrast, most nonphysician licensed Acupuncturists use a traditional Chinese medicine approach to needle placement. Despite this apparent difference in their predominant styles of acupuncture, there was a high correlation between physician and nonphysician licensed Acupuncturist acupoint selection to treat low back pain. In addition to acupuncture needling, physicians use other medical treatments, whereas nonphysician licensed Acupuncturists' employ a variety of traditional Chinese medicine adjuncts to needling. Conclusion This study provides new information about the nature of physician acupuncture practice in the United States and how it compares to acupuncture provided by nonphysician licensed Acupuncturists. Further research is necessary to determine if the different types of acupuncture provided by physicians and nonphysician Acupuncturists affect treatment outcomes and costs for patients with chronic low back pain.

  • Yin scores and yang scores: A new method for quantitative diagnostic evaluation in traditional Chinese medicine research.
    Journal of alternative and complementary medicine (New York N.Y.), 2004
    Co-Authors: Helene M. Langevin, Karen J. Sherman, Gary J. Badger, Bonnie K. Povolny, Robert T Davis, Alexander C. Johnston, Janet Kahn, Ted J. Kaptchuk
    Abstract:

    Objective: To develop and evaluate a method for quantitative evaluation of yin and yang (yin and yang scores) in human subjects for the purposes of research. This method aims to classify subjects into groups allowing future quantitative testing of key research questions such as: do different groups of patients respond differently to acupuncture treatments or Chinese herb formulas? Methods: In a pilot study of inter-rater reliability, 12 volunteers were each successively interviewed and examined by 6 Acupuncturists on the same day. Each Acupuncturist gave each volunteer a score for yin and a score for yang on a scale of -10 to +10, zero representing a "balanced" score. Acupuncturists were blinded to each other's scores. Results: Overall mean (±standard deviation [SD]) yin and yang scores were -1.86 ± 0.90 and -0.68 ± 1.23 respectively. Intraclass correlations (ICCs) associated with a single Acupuncturist's ratings were 0.35 (yin) and 0.36 (yang). ICC's for subject's mean scores based on the six acupuncturi...

  • Characteristics of licensed Acupuncturists, chiropractors, massage therapists, and naturopathic physicians.
    The Journal of the American Board of Family Practice, 2002
    Co-Authors: Daniel C. Cherkin, Karen J. Sherman, Andrea Hrbek, Richard A. Deyo, L. Gary Hart, Janet H. Street, Elaine H. Cramer, Bruce Milliman, Jennifer Booker, Robert D. Mootz
    Abstract:

    BACKGROUND Despite growing popularity of complementary and alternative medical (CAM) therapies, little is known about the patients seen by CAM practitioners. Our objective was to describe the patients and problems seen by CAM practitioners. METHODS We collected data on 20 consecutive visits to randomly sampled licensed Acupuncturists, chiropractors, massage therapists, and naturopathic physicians practicing in Arizona, Connecticut, Massachusetts, and Washington. Data were collected on patient demographics, smoking status, referral source, reasons for visit, concurrent medical care, payment source, and visit duration. Comparative data for conventional physicians were drawn from the National Ambulatory Medical Care Survey. RESULTS In each profession, at least 99 practitioners collected data on more than 1,800 visits. More than 80% of visits to CAM providers were by young and middle-aged adults, and roughly two thirds were by women. Children comprised 10% of visits to naturopathic physicians but only 1% to 4% of all visits to other CAM providers. At least two thirds of visits resulted from self-referrals, and only 4% to 12% of visits were from conventional physician referrals. Chiropractors and massage therapists primarily saw musculoskeletal problems, while Acupuncturists and naturopathic physicians saw a broader range of conditions. Visits to Acupuncturists and massage therapists lasted about 60 minutes compared with 40 minutes for naturopathic physicians and less than 20 minutes for chiropractors. Most visits to chiropractors and naturopathic physicians, but less than one third of visits to Acupuncturists and massage therapists, were covered by insurance. CONCLUSIONS This information will help inform discussions of the roles CAM practitioners will play in the health care system of the future.

  • Acupuncture for chronic low back pain: diagnosis and treatment patterns among Acupuncturists evaluating the same patient. (Washington University School of Medicine, St. Louis, MO) Southern Med J. 2001;94:486–492.
    Pain Practice, 2001
    Co-Authors: Donna Kalauokalani, Karen J. Sherman, Daniel C. Cherkin
    Abstract:

    In this case study 7 office-based Acupuncturists practicing Traditional Chinese Medicine evaluated the same patient with chronic low back pain and provided data regarding principal assessment techniques, diagnoses, and therapeutic recommendations. A high diagnostic agreement existed among 5 of 7 Acupuncturists. However, recommended treatments included varying numbers and locations of acupuncture points. Recommendations varied between 5 and 14 points requiring 7 to 26 needles, since many points were intended for bilateral application. Of 28 acupuncture points selected, only 4 (14%) were prescribed by 2 or more Acupuncturists. Most recommended various forms of adjuvant heat. Conclude that 7 Acupuncturists agreed considerably in the diagnoses for the same patient with chronic low back pain, but treatment recommendations varied substantially. Clinicians and researchers must recognize treatment recommendation variations and the challenges they present for study design interpretation.

  • mechanical signaling through connective tissue a mechanism for the therapeutic effect of acupuncture
    The FASEB Journal, 2001
    Co-Authors: Helene M. Langevin, David L Churchill, Marilyn J Cipolla
    Abstract:

    The mechanism of action of acupuncture remains largely unknown. The reaction to acupuncture needling known as 'de qi', widely viewed as essential to the therapeutic effect of acupuncture, may be a key to understanding its mechanism of action. De qi includes a characteristic needling sensation, perceived by the patient, and 'needle grasp' perceived by the Acupuncturist. During needle grasp, the Acupuncturist feels pulling and increased resistance to further movement of the inserted needle. We hypothesize that 1) needle grasp is due to mechanical coupling between the needle and connective tissue with winding of tissue around the needle during needle rotation and 2) needle manipulation transmits a mechanical signal to connective tissue cells via mechanotransduction. Such a mechanism may explain local and remote, as well as long-term effects of acupuncture.

  • unilateral and immediate stimulation of acupuncture points xiaohai si8 and jianwaishu si14 of the small intestine meridian increases electromyographic activity and strength in the ipsilateral and contralateral upper trapezius muscle
    Journal of Acupuncture and Meridian Studies, 2016
    Co-Authors: Leandro L De Souza, Fernanda Lopes Buiatti De Araujo, Fernanda Machado Da Silva, Thais S Mucciaroni, Joao Eduardo De Araujo
    Abstract:

    Abstract We previously showed that a yin meridian of the upper limb decreased electromyographic activity (root mean square) and muscle strength ipsilateral and contralateral to the side of stimulation. Here, we tested the upper trapezius (UT) muscle response after stimulation of a yang meridian of the upper limb, the small intestine (SI). Thirty-eight healthy volunteers were randomized into the following groups: UT muscle (SI14), distant of the UT muscle (SI8), without stimulation (CG), and sham (R3). An Acupuncturist certificated by the Brazilian Society of Physical Therapists and Acupuncturists performed the needle insertion. Each volunteer received only one stimulation to the right upper limb. The evaluation occurred before, 5 minutes after, and 20 minutes after needle withdrawal. The root mean square activity increased on the right side in the UT muscle for the SI8 and SI14 groups ( F 3,37  = 4.67; p F 3,37  = 4.52; p F 3,37  = 3.41; p

The root mean square activity increased on the right side in the UT muscle for the SI8 and SI14 groups (F3,37 = 4.67; p < 0.025) at the 20-minute evaluation. The most vigorous response occurred on the contralateral side because the effects were maintained for 5 minutes after withdrawal (F3,37 = 4.52; p < 0.025). Both groups showed an increase in the UT muscle strength at the 20-minute evaluation (F3,37 = 3.41; p < 0.025). The CG and R3 groups did not show any changes. Our data indicate that SI a yang meridian increases the UT muscle response.
