In.ether.Ards,.sham'.r 'placebo' acupuncture generally produces the same effects as 'real' acupuncture and, in some cases, does better.” 77 A 2013 meta-analysis found little evidence that the effectiveness of acupuncture on pain compared to sham was modified by the location of the needles, the number of needles used, the experience or technique of the practitioner, or by the circumstances of the sessions. 78 The same analysis also suggested that the number of needles and sessions is important, as greater numbers improved the outcomes of acupuncture compared to non-acupuncture controls. 78 There has been little systematic investigation of which components of an acupuncture session may be important for any therapeutic effect, including needle placement and depth, type and intensity of stimulation, and number of needles used. 75 The research seems to suggest that needles do not need to stimulate the traditionally specified acupuncture points or penetrate the skin to attain an anticipated effect e.g. psychosocial factors. 2 A response to “sham” acupuncture in osteoarthritis may be used in the elderly, but placebos have usually been regarded as deception and thus unethical. 79 However, some physicians and ethicists have suggested circumstances for applicable uses for placebos such as it might present a theoretical advantage of an inexpensive treatment without adverse reactions or interactions with drugs or other medications. 79 As the evidence for most types of alternative medicine such as acupuncture is far from strong, the use of alternative medicine in regular healthcare can present an ethical question. 80 Using the principles of evidence-based medicine to research acupuncture is controversial, and has produced different results. 71 Some research suggests acupuncture can alleviate pain but the majority of research suggests that acupuncture's effects are mainly due to placebo. 9 Evidence suggests that any benefits of acupuncture are short-listing. 14 There is insufficient evidence to support use of acupuncture compared to mainstream medical treatments . 81 Acupuncture is not better than mainstream treatment in the long term. 74 Publication bias is cited as a concern in the reviews of randomized controlled trials CRTs of acupuncture. 57 82 83 A 1998 review of studies on acupuncture found that trials originating in Cina, Japan, Hong Kong, and Taiwan were uniformly favourable to acupuncture, as were ten out of eleven studies conducted in Russia. 84 A 2011 assessment of the quality of CRTs on ACM, including acupuncture, concluded that the methodological quality of most such trials including randomization, experimental control, and blinding was generally poor, particularly for trials published in Cinese journals though the quality of acupuncture trials was better than the trials testing ACM remedies. 85 The study also found that trials published in non-Chinese journals tended to be of higher quality. 85 Chinese authors use more Chinese studies, which have been demonstrated to be uniformly positive. 86 A 2012 review of 88 systematic reviews of acupuncture published in Chinese journals found that less than half of these reviews reported testing for publication bias, and that the majority of these reviews were published in journals with impact factors of zero. 87 Scientist and journalist Steven Salzburg identifies acupuncture and Chinese medicine generally as a focus for “fake medical journals” such as the Journal of Acupuncture and Meridian Studies and Acupuncture in Medicine . 88 The conclusions of many trials and numerous systematic reviews of acupuncture are largely inconsistent with each other. 13 A 2011 systematic review of systematic reviews found that for reducing pain, real acupuncture was no better than sham acupuncture, and concluded that numerous reviews have shown little convincing evidence that acupuncture is an effective treatment for reducing pain. 10 The same review found that neck pain was one of only four types of pain for which a positive effect was suggested, but cautioned that the primary studies used carried a considerable risk of bias. 10 A 2009 overview of Cochran reviews found acupuncture is not effective for a wide range of conditions, and suggested that it may be effective for only chemotherapy-induced nausea/vomiting, postoperative nausea/vomiting, and idiopathic headache. 13 A 2014 systematic review suggests that the nocebo effect of acupuncture is clinically relevant and that the rate of adverse events may be a gauge of the nocebo effect. 89 According to the 2014 Miller's anaesthesia book, “when compared with placebo, acupuncture treatment has proven efficacy for relieving pain”. 44 A 2012 meta-analysis conducted by the Acupuncture Trialists' Collaboration found “relatively modest” efficiency of acupuncture in comparison to sham for the treatment of four different types of chronic pain back and neck pain, knee osteoarthritis, chronic headache, and shoulder pain and on that basis concluded that it “is more than a placebo” and a reasonable referral option. 90 Commenting on this meta-analysis, both Eduard Ernst and David Colquhoun said the results were of negligible clinical significance. 91 92 Eduard Ernst later stated that “I fear that, once we manage to eliminate this bias that operators are not blind … we might find that the effects of acupuncture exclusively are a placebo response.” 93 A 2010 systematic review suggested that acupuncture is more than a placebo for commonly occurring chronic pain conditions, but the authors acknowledged that it is still unknown if the overall benefit is clinically meaningful or cost-effective. 94 A 2010 review found real acupuncture and sham acupuncture produce similar improvements, which can only be accepted as evidence against the efficacy of acupuncture. 95 The same review found limited Acupuncture evidence that real acupuncture and sham acupuncture appear to produce biological differences despite similar effects. 95 A 2009 systematic review and meta-analysis found that acupuncture had a small analgesic effect, which appeared to lack any clinical importance and could not be discerned from bias. 15 The same review found that it remains unclear whether acupuncture reduces pain independent of a psychological impact of the needling ritual. 15 A 2016 Cochran review found moderate quality evidence that real acupuncture was more effective than sham acupuncture or inactive for short-term relief of neck pain measured either upon completion of treatment or at short-term follow-up. 96 A 2013 meta-analysis found that acupuncture was better than no treatment for reducing lower back pain, but not better than sham acupuncture, and concluded that the effect of acupuncture “is likely to be produced by the non-specific effects of manipulation”. 97 A 2013 systematic review found supportive evidence that real acupuncture may be more effective than sham acupuncture with respect to relieving lower back pain, but there were methodological limitations with the studies. 98 A 2013 systematic review found that acupuncture may be effective for non-specific lower back pain, but the authors noted there were limitations in the studies examined, such as heterogeneity in study characteristics and low methodological quality in many studies. 99 A 2012 systematic review found some supporting evidence that acupuncture was more effective than no treatment for chronic non-specific low back pain; the evidence was conflicting comparing the effectiveness over other treatment approaches. 12 A 2011 systematic review of systematic reviews found that “for chronic low back pain, individualized acupuncture is not better in reducing symptoms than formula acupuncture or sham acupuncture with a toothpick that does not penetrate the skin.” 10 A 2010 review found that sham acupuncture was as effective as real acupuncture for chronic low back pain. 2 The specific therapeutic effects of acupuncture were small, whereas its clinically relevant benefits were mostly due to contextual and psychosocial circumstances. 2 Brain imaging studies have shown that traditional acupuncture and sham acupuncture differ in their effect on limbic structures, while at the same time showed equivalent analgesic effects. 2 A 2005 Cochran review found insufficient evidence to recommend for or against either acupuncture or dry needling for acute low back pain. 100 The same review found low quality evidence for pain relief and improvement compared Sun simian published acupuncture-related diagrams and charts that established standardized methods for finding acupuncture sites on people of different sizes and categorized acupuncture sites in a set of modules. 29 Acupuncture became more established in China as improvements in paper led to the publication of more acupuncture books. Sometimes needles were used while they were still hot, creating a cauterizing effect at the injection site. 29 :104 Nine needles were recommended in the Ben chi Ta Cheng from 1601, which may have been because of an ancient Chinese belief that nine was a magic number. 29 :102-103 Other belief systems were based on the idea that the human body operated are still unable to find a shred of evidence to support the existence of meridians or Ch'i”, 21 “The traditional principles of acupuncture are deeply flawed, as there is no evidence at all to demonstrate the existence of Ch'i or meridians” 22 and “As yin and yang, acupuncture points and meridians are not a reality, but merely the product of an ancient Chinese philosophy”. 23 Tyne, D.; Shenker, N..>Acupuncture.Tote..s..orm.f.lternative.edicine..n which thin needles are inserted into the body. 3 It is a key component of traditional Chinese medicine ACM. 4 ACM theory and practice are not based upon scientific knowledge, 5 and acupuncture is a pseudo-science . 6 7 There is a diverse range of acupuncture theories based on different philosophies, 8 and techniques vary depending on the country. 9 The method used in ACM is likely the most widespread in the US. 2 It is most often used for pain relief, 10 11 though it is also used for a wide range of other conditions. 4 Acupuncture is generally used only in combination with other forms of treatment. 12 The conclusions of many trials and numerous systematic reviews of acupuncture are largely inconsistent. 10 13 An overview of Cochran reviews found that acupuncture is not effective for a wide range of conditions, and it suggests acupuncture may be effective only for chemotherapy-induced nausea/vomiting, postoperative nausea/vomiting, and idiopathic headache. 13 A systematic review of systematic reviews found little evidence of acupuncture's effectiveness in treating pain. 10 The evidence suggests that short-term treatment with acupuncture does not produce long-term benefits. 14 Some research results suggest acupuncture can alleviate pain, though the majority of research suggests that acupuncture's effects are mainly due to placebo . 9 A systematic review concluded that the analgesic effect of acupuncture seemed to lack clinical relevance and cGould not be clearly distinguished from bias. 15 Acupuncture is generally safe when done by an appropriately trained practitioner using clean needle technique and single-use needles. 16 17 When properly delivered, it has a low rate of mostly minor adverse effects . 3 16 Accidents and infections are associated with infractions of sterile technique or neglect of the practitioner. 17 A review stated that the reports of infection transmission increased significantly in the prior decade. 18 The most frequently reported adverse events were pneumothorax and infections. 10 Since serious adverse events continue to be reported, it is recommended that acupuncturists be trained sufficiently to reduce the risk. 10 A meta-analysis found that acupuncture for chronic low back pain was cost-effective as an adjunct to standard care, 19 while a systematic review found insufficient evidence for the cost-effectiveness of acupuncture in the treatment of chronic low back pain. 20 Scientific investigation has not found any histological or physiological evidence for traditional Chinese concepts such as qi, meridians, and acupuncture points, n 1 24 and many modern practitioners no longer support the existence of life force energy qi flowing through meridians, which was a major part of early belief systems. 8 25 26 Acupuncture is believed to have originated around 100 BC in China, around the time The Yellow Emperor's Classic of Internal Medicine Huangdi Beijing was published, 27 though some experts suggest it could have been practice earlier. 9 Over time, conflicting claims and belief systems emerged about the effect of lunar, celestial and earthly cycles, yin and yang energies, and a body's “rhythm” on the effectiveness of treatment. 28 Acupuncture grew and diminished in popularity cupping in China. In.999, the National enter for Complementary and Acupuncture chart from Shisi Ming fahui Expression of the Fourteen Meridians written by Hun thou Al. 1340s, Ming dynasty . Even.f.hey.ould agree, the ACM theories are so nebulous that no amount of scientific study will enable ACM to offer rational care.” 5 Some modern practitioners support the use of acupuncture to treat pain, but have abandoned the use of qi, meridians, yin, yang and other energies based in mysticism, as explanatory frameworks. 8 25 26 The use of qi as an explanatory framework has been decreasing in China, even as it becomes more prominent during discussions of acupuncture in the US. 257 Academic discussions of acupuncture still make reference to pseudo-scientific concepts such as qi and meridians despite the lack of scientific evidence. 257 Many within the scientific community consider attempts to rationalize acupuncture in science to be quackery, pseudo-science and “theatrical placebo”. 258 Academics Massimo Pigliucci and marten Boudry describe it as a “borderlands science” lying between science and pseudo-science. 259 Many acupuncturists attribute pain relief to the release of endorphins when needles penetrate, but no longer support the idea that acupuncture can affect a disease. 26 257 It is a generally held belief within the acupuncture community that acupuncture points and meridians structures are special conduits for electrical signals but no research has established any consistent anatomical structure or function for either acupuncture points or meridians. n 1 24 Human tests to determine whether electrical continuity was significantly different near meridians than other places in the body have been inconclusive. 24 Some studies suggest acupuncture causes a series of events within the central nervous system, 260 and that it is possible to inhibit acupuncture's analgesic effects with the opioid antagonist naloxone . 261 Mechanical deformation of the skin by acupuncture needles appears to result in the release of adenosine . 2 The anti-nociceptive effect of acupuncture may be mediated by the adenosine A1 receptor . 262 A 2014 Nature Reviews Cancer review article found that since the key mouse studies that suggested acupuncture relieves the body, and eventually to balancing Yin and Yang energies as well. 28 According to Dr.
Although acupuncture declined in China during this time period, it was also growing in popularity in other countries. 30 or a very weak constitution of the patient can be considered, all of which are thought to decrease the likelihood of successful treatment. Korea is believed to be the first country in Asia that acupuncture spread to outside of China. 29 Within Korea there is a legend that acupuncture was developed by emperor Dan gun, Needles. 48 Japanese acupuncturists use extremely thin needles that are used superficially, sometimes without penetrating the skin, and surrounded by a guide tube a 17th-century invention adopted in China and the West. A woman receiving fire skin is sterilized and needles are inserted, frequently with a plastic guide tube. In ACM, the four diagnostic methods are: inspection, on a rhythm and acupuncture had to be applied at the right point in the rhythm to be effective. 29 :140-141 In some cases a lack of balance between Yin and Yang were believed to be the cause of disease. 29 :140-141 In the 1st century AD, many of the first books about acupuncture were published and recognized acupuncturist experts began to emerge.
