Acupuncture for pain and osteoarthritis of the knee: a pilot study for an open parallel-arm randomised controlled trial

BackgroundThere is some evidence that acupuncture for pain and osteoarthritis (OA) of the knee is more than a placebo, and short term clinical benefits have been observed when acupuncture is compared to usual care. However there is insufficient evidence on whether clinical benefits of acupuncture are sustained over the longer term. In this study our key objectives are to inform the design parameters for a fully powered pragmatic randomised controlled trial. These objectives include establishing potential recruitment rates, appropriate validated outcome measures, attendance levels for acupuncture treatment, loss to follow up and the sample size for a full scale trial.MethodsPotential participants aged over 50 with pain and osteoarthritis of the knee were identified from a GP database. Eligible patients were randomised to either 'acupuncture plus usual care' and 'usual care' alone, with allocation appropriately concealed. Acupuncture consisted of up to 10 sessions usually weekly. Outcome measures included Western Ontario and McMaster Universities (WOMAC) index with the sample size for a full scale trial determined from the variance.ResultsFrom the GP database of 15,927 patients, 335 potential trial participants were identified and invited to participate. After screening responses, 78 (23%) were identified as eligible and 30 patients who responded most promptly were randomised to 'acupuncture plus usual care' (15 patients) and 'usual care' alone (15 patients). Attendance for acupuncture appointments was high at 90% of the maximum. Although the trial was not powered to detect significant changes in outcome, the WOMAC pain index showed a statistically significant reduction at 3 months in the acupuncture group compared to usual care. This was not sustained at 12 months. The sample size for a fully powered two-arm trial was estimated to be 350.ConclusionThis pilot study provided the evidence that a fully powered study to explore the longer term impact of acupuncture would be worthwhile, and relevant design features for such a trial were determined.Trial registration numberISRCTN25134802.

Still Looking for Effective Nonhormonal Hot Flash Therapies

Bothersome hot flashes, which affect more than half of postmenopausal women, are effectively treated with estrogens; however, adverse effects have prompted efforts to identify effective nonestrogenic therapies. Now, three studies add to our knowledge about the effectiveness of such approaches for treating hot flashes. In a randomized Norwegian study, investigators assessed the effects of acupuncture plus self-provided care (e.g., soy, herbs, physical activity, and relaxation techniques) or self-care alone on hot flash frequency and intensity in 248 postmenopausal women. At 12 weeks, women in the acupuncture group …

Tunbridge Wells Homeopathic Hospital outcome study

To assess health changes seen in routine homeopathic and acupuncture care for patients with a wide range of chronic conditions who were referred to a hospital outpatient department. Observational study of consecutive follow-up patients during a nearly 7- year period (I st Jan 1999–Nov 2006). Hospital outpatient unit within an acute National Health Service (NHS) Trust in the United Kingdom. Every patient attending the hospital outpatient unit for a follow-up appointment over the study period was included, commencing with their first follow-up attendance. Outcomes were based on scores on a 7-point Likerttype scale at all follow up consultations and were assessed as overall outcomes compared to the initial baseline assessments. A total of 15,249 consecutive follow-up appointments from 4.571 patients were given outcome scores. 77% reported positive health changes; 21 % little better (+1), 25% moderately better (+2) and 31 % reported to be much better (+3). A condition specific analysis of improvement over time is presented. The most common conditions seen were eczema, menopause, CFS, IBS, osteoarthritis, depression and migraine. Homeopathy and acupuncture seem to have a positive effect in a substantial proportion of this large cohort of patients with complex chronic conditions and previous unsatisfactory response to conventional treatment. Further research needs to look at the most promising conditions using more reliable designs and include an assessment of all the patients who were lost to follow up.

Patient satisfaction with routine care acupuncture in chronic pain conditions—Does gender play a role?

Objectives To analyze whether gender aspects have an impact on patient satisfaction and global assessment of therapeutic success addressing both patient's and therapist's sex. Methods 5.109 patients (mean age 55, sd 15 years) with chronic pain conditions from an observational acupuncture study were included into this secondary analysis. For each patient sex and medical specialty of the treating acupuncturist were known. Patient satisfaction was assessed after last acupuncture session by EuroPep questionnaire [Grol et al., Br J Gen Pract 2000;50:882–7] covering different aspects of care. Effectiveness of treatment was assessed by a global rating of patient and physician. Statistical analysis was performed by general linear models with multiple factors. Results The percentage of female patients was 83%, and 35% of the patients were treated by a female therapist indicating that more female patients were treated by female therapists than expected by chance ( p p p Conclusions Patient satisfaction was lowest when treated by orthopedists; patients treated by female acupuncturists showed higher satisfaction. Since distribution of patients’ sex was extremely skewed, further analyses with respect to age and pain condition were limited.

Safety and Efficacy of Acupuncture in Children

Acupuncture has been used therapeutically in China for thousands of years and is growing in prominence in Europe and the United States. In a recent review of complementary and alternative medicine use in the US population, an estimated 2.1 million people or 1.1% of the population sought acupuncture care during the past 12 months. Four percent of the US population used acupuncture at any time in their lives. We reviewed 31 different published journal articles, including 23 randomized controlled clinical trials and 8 meta-analysis/systematic reviews. We found evidence of some efficacy and low risk associated with acupuncture in pediatrics. From all the conditions we reviewed, the most extensive research has looked into acupuncture's role in managing postoperative and chemotherapy-induced nausea/vomiting. Postoperatively, there is far more evidence of acupuncture's efficacy for pediatrics than for children treated with chemotherapy. Acupuncture seems to be most effective in preventing postoperative induced nausea in children. For adults, research shows that acupuncture can inhibit chemotherapy-related acute vomiting, but conclusions about its effects in pediatrics cannot be made on the basis of the available published clinical trials data to date. Besides nausea and vomiting, research conducted in pain has yielded the most convincing results on acupuncture efficacy. Musculoskeletal and cancer-related pain commonly affects children and adults, but unfortunately, mostly adult studies have been conducted thus far. Because the manifestations of pain can be different in children than in adults, data cannot be extrapolated from adult research. Systematic reviews have shown that existing data often lack adequate control groups and sample sizes. Vas et al, Alimi et al, and Mehling et al demonstrated some relief for adults treated with acupuncture but we could not find any well-conducted randomized controlled studies that looked at pediatrics and acupuncture exclusively. Pain is often unresolved from drug therapy, thus there is a need for more studies in this setting. For seasonal allergic rhinitis, we reviewed studies conducted by Ng et al and Xue et al in children and adults, respectively. Both populations showed some relief of symptoms through acupuncture, but questions remain about treatment logistics. Additionally, there are limited indications that acupuncture may help cure children afflicted with nocturnal enuresis. Systematic reviews show that current published trials have suffered from low trial quality, including small sample sizes. Other areas of pediatric afflictions we reviewed that suffer from lack of research include asthma, other neurologic conditions, gastrointestinal disorders, and addiction. Acupuncture has become a dominant complementary and alternative modality in clinical practice today, but its associated risk has been questioned. The National Institutes of Health Consensus Statement states "one of the advantages of acupuncture is that the incidence of adverse effects is substantially lower than that of many drugs or other accepted procedures for the same conditions." A review of serious adverse events by White et al found the risk of a major complication occurring to have an incidence between 1:10,000 and 1:100,000, which is considered "very low." Another study found that the risk of a serious adverse event occurring from acupuncture therapy is the same as taking penicillin. The safety of acupuncture is a serious concern, particularly in pediatrics. Because acupuncture's mechanism is not known, the use of needles in children becomes questionable. For example, acupoints on the vertex of infants should not be needled when the fontanel is not closed. It is also advisable to apply few needles or delay treatment to the children who have overeaten, are overfatigued, or are very weak. Through our review of pediatric adverse events, we found a 1.55 risk of adverse events occurring in 100 treatments of acupuncture that coincides with the low risk detailed in the studies mentioned previously. The actual risk to an individual patient is hard to determine because certain patients, such as an immunosuppressed patient, can be predisposed to an increased risk, acupuncturist's qualifications differ, and practices vary in certain parts of the world. Nevertheless, it seems acupuncture is a safe complementary/alternative medicine modality for pediatric patients on the basis of the data we reviewed.

Self-help advice as a process integral to traditional acupuncture care: Implications for trial design

In the literature on acupuncture research, the active (or specific) component of acupuncture is almost always presented as acupuncture needling alone. However, specific components, by definition, should include all interventions driven by acupuncture theory that are also believed to be causally associated with outcome. In this paper, we explore the delivery of self-help advice as a component of the process of acupuncture care, and discuss the implications for future trial designs. In a nested qualitative study, six acupuncturists were interviewed about the treatments they provided within a pragmatic clinical trial. The acupuncturists practised individualised acupuncture according to traditional principles. Audiotapes were transcribed and coded and the contents analysed by case and by theme. The analysis focuses on a priori and emergent themes associated with the process of delivering self-help advice as described by the practitioners. Individualised self-help advice is seen by practitioners as being an integral part of the acupuncture treatment that they provide for patients with low back pain. Several categories of generic advice were described; all were embedded in the acupuncture diagnosis. These included; movement, exercise and stretching to move 'qi stagnation'; rest in cases of 'qi deficiency'; diet when the digestive system was compromised; protection from the elements where indicated by the diagnosis, e.g. Bi Syndrome. According to the practitioners, longer-term benefits require the active participation of patients in their self-care. Simplified concepts derived from acupuncture theory, such as 'stagnation' and 'energy', are employed as an integral part of the process of care, in order to engage patients in lifestyle changes, help them to understand their condition, and to see ways in which they can help themselves. Within acupuncture care, self-help advice is not seen as an 'add-on' but rather as an integral and interactive component of a theory-based complex intervention. Studies designed to evaluate the overall effectiveness of traditional acupuncture should accommodate the full range of therapeutic components, strategies and related patient-centred treatment processes. In acupuncture trials, non-needling components, such as self-help advice, when drawn directly from the diagnosis and integral to the process of care, should not be misclassified as incidental, non-specific, or placebo if we are to accurately assess the value of treatment as delivered.

Acupuncture Care for Breast Cancer Patients During Chemotherapy: A Feasibility Study

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

Beyond Needling—Therapeutic Processes in Acupuncture Care: A Qualitative Study Nested Within a Low-Back Pain Trial

In the medical and scientific literature, there is a dearth of reports about how acupuncturists work and deliver care in practice. An informed characterization of the treatment process is needed to support the appropriate design of evaluative studies in acupuncture. The design was that of a nested qualitative study within a pragmatic clinical trial. Six acupuncturists who treated up to 25 patients each were interviewed after the treatment phase of the trial to obtain an account of their experiences of providing acupuncture care to patients with low back pain referred by their GP. Using semistructured interviews and a topic guide, data were collected and analyzed for both a priori and emergent themes. This paper focuses on practitioners' accounts of the goals and processes of care, and describes the strategies employed in addition to needling and other hands-on treatments. From the interview data, it is clear that a coherent body of theoretical knowledge informed clinical decisions and practice, and that the goals of treatment went beyond the alleviation of immediate pain-related symptoms. Acupuncturists in this study all described a pattern of patient-centered care based on a therapeutic partnership. Study participants confirmed the importance of three processes that characterized acupuncture care in this trial, each contributing to the goal of a positive long-term outcome; building a therapeutic relationship; individualizing care; and facilitating the active engagement of patients in their own recovery. Acupuncturists described elements of care that characterized these processes including establishing rapport, facilitating communication throughout the period of care, using an interactive diagnostic process, matching treatment to the individual patient, and the use of explanatory models from Chinese medicine to aid the development of a shared understanding of the patient's condition and to motivate lifestyle changes that reinforce the potential for a recovery of health. Acupuncturists did not view these therapeutic goals, processes, and strategies as a departure from their usual practice. This study suggests that acupuncture care for patients with chronic conditions such as low back pain is likely to be a complex intervention that utilizes a number of patient-centered strategies to elicit longterm therapeutic benefits. Research designed to evaluate the effectiveness of acupuncture as it is practiced in the UK needs to accommodate the full range of therapeutic goals and related treatment processes.

Introducing Voluntary Donations to Fund Primary Care Acupuncture – a User Survey

An acupuncture clinic has been running in general practice without any funding for nine years. However, reorganisation of the health service meant that it had to become self-funding. A scheme for voluntary donations was introduced, with a target of ł15 per treatment. In the first six months, the scheme covered the clinic's costs. A user survey was undertaken to elicit patients' views on the scheme. The majority of patients thought that the scheme was a good idea, and the amount about right. However, a few patients found payment difficult, and stated that they would be less likely to use the service for that reason, or feel guilty about using it without paying. This information should be used to try to obtain public funding through public funds in the future.

Longer term clinical and economic benefits of offering acupuncture care to patients with chronic low back pain

To test whether patients with persistent non-specific low back pain, when offered access to traditional acupuncture care alongside conventional primary care, gained more long-term relief from pain than those offered conventional care only, for equal or less cost. Safety and acceptability of acupuncture care to patients, and the heterogeneity of outcomes were also tested. A pragmatic, two parallel group, randomised controlled trial. Patients in the experimental arm were offered the option of referral to the acupuncture service comprising six acupuncturists. The control group received usual care from their general practitioner (GP). Eligible patients were randomised in a ratio of 2:1 to the offer of acupuncture to allow between-acupuncturist effects to be tested. Three non-NHS acupuncture clinics, with referrals from 39 GPs working in 16 practices in York, UK. Patients aged 18-65 years with non-specific low back pain of 4-52 weeks' duration, assessed as suitable for primary care management by their general practitioner. The trial protocol allowed up to ten individualised acupuncture treatments per patient. The acupuncturist determined the content and the number of treatments according to patient need. The Short Form 36 (SF-36) Bodily Pain dimension (range 0-100 points), assessed at baseline, and 3, 12 and 24 months. The study was powered to detect a 10-point difference between groups at 12 months post-randomisation. Cost--utility analysis was conducted at 24 months using the EuroQoL 5 Dimensions (EQ-5D) and a preference-based single index measure derived from the SF-36 (SF-6D). Secondary outcomes included the McGill Present Pain Index (PPI), Oswestry Pain Disability Index (ODI), all other SF-36 dimensions, medication use, pain-free months in the past year, worry about back pain, satisfaction with care received, and safety and acceptability of acupuncture care. A total of 159 patients were in the 'acupuncture offer' arm and 80 in the 'usual care' arm. All 159 patients randomised to the offer of acupuncture care chose to receive acupuncture treatment, and received an average of eight acupuncture treatments within the trial. Analysis of covariance, adjusting for baseline score, found an intervention effect of 5.6 points on the SF-36 Pain dimension [95% confidence interval (CI) -1.3 to 12.5] in favour of the acupuncture group at 12 months, and 8 points (95% CI 0.7 to 15.3) at 24 months. No evidence of heterogeneity of effect was found for the different acupuncturists. Patients receiving acupuncture care did not report any serious or life-threatening events. No significant treatment effect was found for any of the SF-36 dimensions other than Pain, or for the PPI or the ODI. Patients receiving acupuncture care reported a significantly greater reduction in worry about their back pain at 12 and 24 months compared with the usual care group. At 24 months, the acupuncture care group was significantly more likely to report 12 months pain free and less likely to report the use of medication for pain relief. The acupuncture service was found to be cost-effective at 24 months; the estimated cost per quality-adjusted (QALY) was 4241 pounds sterling (95% CI 191 pounds sterling to 28,026 pounds sterling) using the SF-6D scoring algorithm based on responses to the SF-36, and 3598 pounds sterling (95% CI 189 pounds sterling to 22,035 pounds sterling) using the EQ-5D health status instrument. The NHS costs were greater in the acupuncture care group than in the usual care group. However, the additional resource use was less than the costs of the acupuncture treatment itself, suggesting that some usual care resource use was offset. Traditional acupuncture care delivered in a primary care setting was safe and acceptable to patients with non-specific low back pain. Acupuncture care and usual care were both associated with clinically significant improvement at 12- and 24-month follow-up. Acupuncture care was significantly more effective in reducing bodily pain than usual care at 24-month follow-up. No benefits relating to function or disability were identified. GP referral to a service providing traditional acupuncture care offers a cost-effective intervention for reducing low back pain over a 2-year period. Further research is needed to examine many aspects of this treatment including its impact compared with other possible short-term packages of care (such as massage, chiropractic or physiotherapy), various aspects of cost-effectiveness, value to patients and implementation protocols.

Dreaming the Dark Side of the Body: Pain as Transformation in Three Ethnographic Cases

The body in‐pain has regularly been relegated to "the dark side"of Western biomedicine, academic research, and even everyday life. Following Starhawk's aptly titled resuscitation of "the dark"as a fertile source of spiritual transformation (Dreaming the Dark, 1982), this essay examines the ways in which intractable pain can open up the body to "a new body in the making" —one that engages with pain kinesthetically as well as discursively. This essay explores three ethnographic cases emerging from three different American fieldvvork sites. An Internet mailing list called WITSENDO constitutes the first case; through often daily participation in this electronic mailing list, women suffering from endometriosis co‐create a virtual community that strikingly mitigates their experiences of chronicand intense pain. The shift in how long‐term clients of acupuncture care regard needling is the locus of the second case. Acupuncture treatments in American clinical settings often negotiate an American cultural assumption that needles are painful; this second case documents what happens to patients' "fear" of needles and experiences of pain after regular acupuncture treatments. The third case focuses on adepth interview with an American doula who provides labor support for women primarily in hospital settings, this interview explores the conditions under which American women in labor experience pain and how alternative birth professionals define and conceive of pain during childbirth.These three ethnographic cases highlight the cultural construction of pain by delving into the ways that pain sufferers and health care practitioners engage with the body‐in‐pain. Such engagements occur in the realm of language ‐ both discursive and kinesthetic language.

Acupuncture: theory, efficacy, and practice.

Traditionally, acupuncture is embedded in naturalistic theories that are compatible with Confucianism and Taoism. Such ideas as yin-yang, qi, dampness, and wind represent East Asian conceptual frameworks that emphasize the reliability of ordinary, human sensory awareness. Many physicians who practice acupuncture reject such prescientific notions. Numerous randomized, controlled trials and more than 25 systematic reviews and meta-analyses have evaluated the clinical efficacy of acupuncture. Evidence from these trials indicates that acupuncture is effective for emesis developing after surgery or chemotherapy in adults and for nausea associated with pregnancy. Good evidence exists that acupuncture is also effective for relieving dental pain. For such conditions as chronic pain, back pain, and headache, the data are equivocal or contradictory. Clinical research on acupuncture poses unique methodologic challenges. Properly performed acupuncture seems to be a safe procedure. Basic-science research provides evidence that begins to offer plausible mechanisms for the presumed physiologic effects of acupuncture. Multiple research approaches have shown that acupuncture activates endogenous opioid mechanisms. Recent data, obtained by using functional magnetic resonance imaging, suggest that acupuncture has regionally specific, quantifiable effects on relevant brain structures. Acupuncture may stimulate gene expression of neuropeptides. The training and provision of acupuncture care in the United States are rapidly expanding.
