About a year ago the editors of Anesthesia & Analgesia solicited a written debate on whether or not acupuncture is effective or simply an elaborate placebo. Four experienced acupuncture researchers agreed to write the pro-acupuncture article, Wang, Harris, Lin and Gan. They asked David Colquhoun to write the con position, and David asked me to write it with him (which, of course, I enthusiastically agreed to do).
The article is fortunately published in open access, and so I can reprint it here (full article is below). What I think David and I convincingly demonstrated is that, according to the usual standards of medicine, acupuncture does not work.
Let me explain what I mean by that. Clinical research can never prove that an intervention has an effect size of zero. Rather, clinical research assumes the null hypothesis, that the treatment does not work, and the burden of proof lies with demonstrating adequate evidence to reject the null hypothesis. So, when being technical, researchers will conclude that a negative study “fails to reject the null hypothesis.”
Osteoarthritis is the “wear and tear” kind of arthritis that many of us develop as we get older. Cartilage becomes less resilient with age, collagen can degenerate, and inflammation and new bone outgrowths (osteophytes) can occur. This leads to pain, crepitus (Rice Krispie type crackling noises with movement), swelling and fluid accumulation in the joints (effusion), and can severely limit activity for some patients. Patellofemoral pain is one of the most common of the repetitive strain injuries and is like an early onset of arthritis.
Since knee osteoarthritis is such a ubiquitous annoyance, home remedies and CAM offerings abound. Previously we have covered a number of CAM options on this blog, including glucosamine, acupuncture, and several others. The American Academy of Orthopaedic Surgeons (AAOS) has just issued a 1200 page report evaluating the evidence for various treatments for knee osteoarthritis short of total knee replacement surgery. A 13 page summary is available online. They have done the heavy lifting for us, reviewing all the available scientific studies for evidence of effectiveness. Here’s what the science says: (I’ve highlighted the ones where the evidence is strong.) (more…)
Note: Lest you think that SBM is becoming “turtles all the way down,” let me apologize for the duplication and explain that I had already written this right before I read Mark Crislip’s Turtle Agony article on Friday. My focus is different, and turtles were only a small part of my article, so I decided to leave the turtles in. If you prefer to avoid a turtle overdose, you can just skip the Turtlepuncture section and go on to the Motion Style Acupuncture section. They are clearly labeled for your convenience.
The “science” of acupuncture trudges ever onward without really getting anywhere. New developments include a report of turtlepuncture and a study about treating low back pain with a new kind of “motion style” acupuncture using passive or active movement while the needles are in place. I found the first amusing and the second unconvincing.
A group of Ridley sea turtles were rescued after being stranded during a cold spell that left them hypothermic and unable to function. In addition to the usual rescue and rehabilitation efforts, two of the turtles, Dexter and Fletcher Moon, were treated with acupuncture. It was intended to “decrease inflammation and swelling on their front flippers, restore a full range of motion on those limbs and help the animals regain their appetites.” It allegedly worked: their appetite and the use of their limbs improved. But without any controlled observations, this is only an anecdotal report and means very little. They might have recovered just as well without the treatment, for all we know.
Lest anyone think I am a heartless bastard, I would like it to be known that I do not like to see any creature suffer or die. I am the kind of person who, when finding a spider in the house, is likely to catch it and toss it outside. I always think, “I can’t squish the end result of 6 billion years of evolution”. Except mosquitoes. Those I squish with glee. Infection vectors can die die die die.
I like animals and hate to see them suffer unnecessarily. Like sticking them with needles. Frontal lobes are nice to have. They can let you know that pain is coming and provide preparation and compensation. Once I had a steel bar smack me on the head, opening up a six-inch cut to the bone. No, my brain was not affected, thank you very much. Everything predates the head trauma. When the ER doc numbed the scalp for sutures, he missed the last half-inch and I felt the needle. Knowing what was going on I steeled myself and let him do the last two sutures with no lidocaine, since the needle hurt only a little worse than the lidocaine injection. I have had many other unpleasant medical procedures in my 56 years but knowing what was coming and understanding why makes it easier to tolerate a needle popping into the knee joint or an abdominal drain being pulled.
Animals, and young humans, lack the ability to comprehend the what and why of pain inflicted as part of medicine. Adults can make a conscious decision to be endure pain and fool themselves into thinking it is of benefit. No pain, no gain. Animals can make no such choice.
For example consider sea turtles, who, apparently, are subjected to all sorts of nonsense at the New England Aquarium including acupuncture and laser therapy. As is obvious, I am no veterinarian, the only animal of which I have any understanding of anatomy and physiology is a human, but even with that background it is remarkable what is reported from New England. I used to say the ‘B’ students went into journalism; given the credulous reporting perhaps the standards have been lowered. They certainly have for marine biologists and veterinarians, who are evidently shortchanged in their education. (more…)
If the “Health Freedom” movement has its way, everyone in the United States will be able to practice medicine. It may be quack medicine but that doesn’t seem to bother them. Short of that, chiropractors, naturopaths and acupuncturists are aiming to reinvent themselves primary care providers and even physicians. As David Gorski pointed out, this will reduce medical doctors to just another iteration of physician, the “allopathic” type, equal in stature to the chiropractic, naturopathic and acupuncture types. These “physicians” already call themselves “doctor” (e.g., “Doctor of Oriental Medicine”) and claim to graduate from four-year “doctoral” programs. This despite the fact that their schools operate outside the mainstream American university system and avoid some of the basics of typical graduate programs, such as entrance exams, as well as the extensive clinical training required for medical doctors.
Consumers are confused by all of this, and who wouldn’t be? In 2008 and 2010, surveys done for the American Medical Association by outside firms revealed that many patients did not know the qualifications of their healthcare provider. The comparisons were between allied health professions (e.g., audiologists and nurse practitioners) and medical doctors, but chiropractors were included. In 2008, 38 per cent of those surveyed (n=850) thought chiropractors were medical doctors, although that dropped to 31 per cent in 2010. Still, we are talking about roughly one-third of the survey participants.
The surveys also asked about the use of the term “physician” and confusion in advertising materials.
Every so often, our “friends” on the other side of the science aisle (i.e., the supporters of “complementary and alternative medicine”—otherwise known as CAM or “integrative medicine”) give me a present when I’m looking for a topic for my weekly bit of brain droppings about medicine, science, and/or why CAM is neither. It’s also been a while since I’ve written about this particular subject; so it’s a win-win for all sides! I get a topic. A certain CAM journal gets extra traffic. And you get the benefit of my usually brilliant deconstruction of dubious science. What could go wrong? I mean, I might not be Mark Crislip, but I do enjoy a good dive into a pile of pseudoscience every now and then. It’s just a weird trait of mine.
In any case, there is a journal called Medical Acupuncture. Sadly, it’s published by a real scientific publisher, Mary Ann Liebert, Inc., a publisher that has a stable of decent, if not top tier, journals. Unfortunately, it also has a stable of CAM journals, including, of course, the aforementioned journal Medical Acupuncture. Because I happen to be on the mailing list for Mary Ann Liebert, Inc., I recently got an e-mail with an announcement:
How Does Acupuncture Work? The Science behind the Therapy Is Explored in a Special Issue of Medical Acupuncture
New Rochelle, NY, April 16, 2013—Even as medical acupuncture is increasingly being validated as an effective treatment for a broad range of medical conditions, what has been missing is an understanding of the basic science and mechanisms of action of this age-old method of healing. A special issue of Medical Acupuncture, a peer-reviewed journal published by Mary Ann Liebert, Inc., publishers presents a series of articles by authors from around the world who provide diverse and insightful perspectives on the science and physiologic responses underlying medical acupuncture. The issue is available free on the Medical Acupuncture website.
“Understanding acupuncture in the same manner that we understand the mechanism of action and pharmacokinetics of a particular drug will, similarly, enable us to match treatments better with conditions,” states Guest Editor Richard F. Hobbs, III, MD. “The net effect will be improved outcomes,” he writes in his editorial “Basic Science Matters.”
For many years I have been using Continuing Medical Education (CME) programs offered by the American Academy of Family Physicians (AAFP). The FP Essentials program consists of a monthly monograph with a post-test that can be submitted electronically for 5 hours of CME credit. Over a 9-year cycle, a complete family medicine curriculum is covered to prepare participants for the re-certification board exams. Some examples of typical subjects are skin cancer, hand and wrist injuries, valvular heart disease, and care of the newborn. I rely on these programs to learn, review, and keep up-to-date in my specialty. Imagine my dismay when I opened the latest package to find a monograph on Integrative Medicine.
First it was called various names like folk medicine, quackery, and unproven/untested treatments, then all of those (the less rational right along with the more rational) were lumped together under the umbrella term “Alternative Medicine,” then it became “Complementary and Alternative Medicine” (CAM), and now it has been re-branded as “Integrative Medicine.” The term is designed to make unscientific treatments seem more acceptable to science-based doctors. “Integrative Medicine” is a marketing term, not a meaningful scientific category. It is a euphemism for combining Complementary and Alternative Medicine (CAM) with mainstream medical practice, unproven with proven, magic with science. It has been critiqued many times on this blog. We have stressed that there is only one medicine, and that when a treatment is proven to work by good evidence, it is just “medicine.” When the evidence for a CAM treatment is not good, it essentially amounts to experimental treatments and/or comfort measures. Worse, sometimes CAM even persists in using treatments that have been proven not to work or that are totally implausible, like therapeutic touch or homeopathy. (more…)
You need to keep an open mind.
A common suggestion offered to naysayers of nonsense.
The usual retort concerns not letting one’s brain fall out.
Evaluating SCAM’s is less about having an open mind and more about having standards, a conceptual framework that is used to interpret and analyze new information. One of the benefits of writing and reading topics covered by science-based medicine (SBM) is it has clarified and sharpened the ideas by which I understand the world. Those concepts were nicely summed up by Steve Novella at Neurologica, and I reproduce them here, slightly modified. They should be on stone tablets, not quite commandants, but strong suggestions. The 8 strong suggestions somehow doesn’t cut it however. (more…)
Acupuncture, or more broadly, Oriental or Traditional Chinese Medicine, is a
weird medley of philosophy, religion, superstition, magic, alchemy, astrology, feng shui, divination, sorcery, demonology and quackery.
And via the particular form of magic known as legislative alchemy, acupuncture is a licensed health care profession in 44 states and the District of Columbia.
A growing body of evidence demonstrates acupuncture is simply an elaborate placebo. Even the CAM-friendly National Center for Complementary and Alternative Medicine, says
Although millions of Americans use acupuncture each year, often for chronic pain, there has been considerable controversy surrounding its value as a therapy and whether it is anything more than placebo.
Someone should tell the state legislatures. (more…)
Electrodermal testing is a bogus procedure where measurements of skin conductance with a biofeedback device are entered into a computer to diagnose nonexistent health problems and “energy imbalances” and to recommend treatments for them, often involving the sale of homeopathic remedies and other useless products. It falls under the general category of EAV (Electro Acupuncture of Voll). The history and variants of EAV are explained in an article on Quackwatch.
I’ve written about electrodermal testing before. I’ve explained how it amounts to fooling patients with a computerized Magic 8 Ball and I’ve discussed the legal and regulatory issues.
Now Stephen Barrett (founder of Quackwatch and Vice-President of the Institute for Science in Medicine) has written an article in FACT (Focus on Alternative and Complementary Therapies) entitled “Bogus electrodermal testing devices: where are the regulators?” He points out that existing regulations are sufficient to ban these devices, but that regulators have failed to take appropriate action.
