As I have noted before, more is published on acupuncture and traditional Chinese pseudo-medicine than the other SCAM. Here are some of the articles that drew my attention.
Captain Hook and acupuncture
Here is one of the more curious articles on acupuncture I have yet to find, “Psychophysical and neurophysiological responses to acupuncture stimulation to incorporated rubber hand.”
I did not know this, but you can fool a person into thinking that a rubber hand is their own.
The synchronous tactile stimulation of the real hand of an individual and rubber hand leads to the feeling that the rubber hand is incorporated with the body of that individual. This is referred to as the rubber hand illusion (RHI), and it occurs because the brain is attempting to interpret the interaction of the visual, tactile, and proprioceptive systems of the body, which in turn, leads to a re-calibration of the touch and the felt position of the hand. The multimodal visuotactile stimulation inherent in the RHI induces the brain to temporarily incorporate external objects into its body image. In addition, when the experimenter threatens the rubber hand with a needle during this illusion, it generally elicits an enhanced sympathetic response and a measurable cortical anxiety response, which indicates that the bodily ownership of the rubber hand causes changes in the interoceptive system of the brain.
Cool. Check out this video to see how it is done. So what happens when you do acupuncture on a rubber hand that the brain thinks is its own?
The findings of the present study clearly demonstrate that acupuncture stimulation to a rubber hand resulted in the experience of the DeQi sensation when the rubber hand was fully incorporated into the body.
As judged by fMRI findings (always taken with a grain of salt substitute) and patient reports. DeQi is what dey feel when de needle is twirled in de skin. (more…)
Back in 2004, data from the 2002 National Health Interview Survey (NHIS) appeared in a report titled “Complementary and Alternative Medicine Use Among Adults: United States, 2002.” It showed a whopping 62% of adults had used CAM in the past 12 months, but only if prayer for health reasons was included. With prayer excluded, the percentage was substantially lower, at 35%.
“CAM” was defined as:
a group of diverse medical and health care systems, therapies, and products that are not presently considered to be part of conventional medicine.
The authors noted that, in earlier surveys of CAM use, “CAM has been operationally defined in a variety of ways” and the lists of CAM interventions/therapies included “varied considerably among the surveys.”
The most commonly used CAM therapies (excluding prayer) were non-vitamin, non-mineral natural products (18.9%), deep breathing exercises (11.6%), chiropractic care (7.5%), yoga (5.1%), massage (5.0%) and diet-based therapies (3.5%). CAM was most often used to treat back pain or problems, head or chest colds, neck pain or problems, joint pain or stiffness, and anxiety or depression. Most CAM use was self-prescribed. Rebranding things like exercise (yoga) as “CAM” was in the mix from the get-go.
Belvidere, NE- Bref Albright was taking an unfamiliar route home from work because of a stalled 18-wheeler when he passed by the cell phone tower. As the electromagnetic field washed over him, symptoms of his sensitivity quickly set in. He first noticed a tingling sensation throughout his body and an odd dryness in his mouth and throat. Then nausea and headache. Once the palpitations and difficulty concentrating on the road began, he knew he had to pull over in order to avoid an accident.

“Getting off the road was the right thing to do,” Albright explained. “I couldn’t risk injuring somebody else if I lost control of my truck, but it left me vulnerable. I was a sitting duck!” As expected, Albright’s condition worsened because of continued exposure to the deadly yet fundamental force of nature. Despite blurry vision and difficulty remembering his wife’s cell phone number, he managed to place a call. No answer. His wife, home brewing kombucha, had left her phone in another room.
Albright, a 53-year-old taxidermist for the Belvidere Parks Commission, then pressed the red button that activated his alternative medical emergency alert system. Within seconds, a satellite had pinpointed the location of Albright’s pendant and a team of emergency alternative medicine experts was soon on its way. While on route, a member of the team was even able to contact Albright’s wife Norleen and ask a few questions about Bref’s alternative medical history.

Last week I gave a quick overview of standard treatment options for migraine, a severe form of recurrent headaches. As promised, this week I will address some common treatments for migraine that I don’t think are supported by the evidence.
Acupuncture is the CAM modality that, it seems to me, has infiltrated the furthest into mainstream medicine, including for the treatment of migraine. In fact the The American Headache Society includes acupuncture on its list of recommended treatments. The reason for this is that acupuncture proponents have been able to change the rules of clinical research so that essentially negative or worthless studies of acupuncture are presented as positive.
I reviewed the evidence for acupuncture and migraine previously, demonstrating the multiple problems with the acupuncture literature in general, and specifically acupuncture in migraines. Most studies suffer from at least one fatal flaw: they are not properly blinded, they do not include a control, they mix acupuncture with non-acupuncture variables (mostly including electrical stimulation in the treatment group), comparison groups are not adequately treated, they make multiple comparisons to maximize chance outcomes, or they are simply too small making them susceptible to all the usual problems of bias in research.
What we don’t see is a consistent and clinically-relevant effect in properly-controlled double-blind trials where the variables of acupuncture are isolated.
SBM frequently receives questions from readers asking for more information or even challenging our position on various topics. We make extensive efforts to answer such questions, since engaging with the public is one of the primary purposes of this blog. In fact, I specifically chose the blog format because of its interactive nature and the ability to rapidly respond to items in the news or being discussed publicly.
Sometimes it’s helpful to provide answers to questions in the form of its own post. I do this when the questions are common or explore some new or interesting angle of a topic. I am also more likely to engage when the questions are polite and genuine.
We recently received the following e-mail which meets all these criteria, so here is my response. I will reprint the e-mail in sections as I address each question.
I have the utmost respect for the scientific method, and we subscribe to the Skeptical Inquirer. I respect much of what your organization does, and I do not believe that Reiki or Therapeutic Touch is effective, unless the person receiving these therapies believe they work. However, your organization seems to go out of its way to disprove things like the benefit of organic produce which has less pesticides than conventional produce. You claim that natural pesticides could be just as harmful. Here are some examples of these natural pesticides: apply 1 tablespoon of canola oil and a few drops of ivory soap to the leaves of plants and vegetables to repel insects. Also, apply 2 TBSPS of hot pepper sauce with a few drops of ivory soap to leaves, use baking soda and water or pureed onions to repel insects. How can you claim that these innocuous substances are as harmful as conventional pesticides?
Several snarks were painfully maimed in the writing of this blog post
I read a lot of the pseudo-medical websites. The writing is at best pedestrian, often turgid, and, at its worst, incoherent. It is rarely either engaging or clever.
Wit, the clever bon mot, the amusing turn of phrase or retort, is rare at best. So rare I cannot think of an example. It is ironic that those who engage in fantastical treatments are so often lacking in cleverness with language and thought. The closest you get to humor are the painfully-lame cartoons at the Natural News. I am sure that the readers will flood the comments with examples of all the clever writing I have missed in the world of pseudo-medicine just to prove me wrong. Not that the reality-based world is much better. It is the rare author on the internet whose style keeps me coming back for more.
But for some reason I found “Dear Science Based Medicine, Just a Few Questions About Acupuncture” funny and engaging, at odds with most of the purple quasi-paranoid articles I normally read. Just the right amount of chatty snarkiness to be enjoyable, at least for me. So refreshing given the style of the usual pro-acupuncture comments. Your millage may vary. (more…)
I am happy to report some good news: chiropractors, naturopaths, acupuncturists and assorted other practitioners of pseudo-medicine didn’t fare too well in the 2013-2014 state legislative sessions.
We’ve been following their legislative efforts all year over at the Society for Science-Based Medicine. Some state legislatures meet in yearly sessions. At the end of the year, pending bills die with the session. Some meet only every other year. Others meet in two-year sessions and, in some of these, legislation introduced in one year carries over to the next year. All states with two-year sessions ended these sessions at the close of 2014, except New Jersey and Virginia. If you want to see how your state operates, several websites can help you: MultiState Associates, National Conference of State Legislatures and StateScape.
Chiropractors are already licensed in all 50 states and all of their practice acts permit the detection and correction of the non-existent subluxation. Having achieved that goal, the focus of chiropractic legislative efforts is to expand their scope of practice (the holy grail, for some, being primary care physician status), turf protection and mandates requiring insurance reimbursement or their inclusion in various activities, such as sports physicals, concussion treatment, and scoliosis detection programs.
The most interesting chiropractic bill, one from Oklahoma, didn’t fall into any of those categories:
Chiropractic physicians in this state shall obtain informed, written consent from a patient prior to performing any procedure that involves treatment of the patient’s cervical spine and such informed consent shall include the risks and possible side effects of such treatment including the risk of chiropractic stroke.
I’m cheating. No, I’m recycling. ‘Tis the season to have to no time to get anything done. Since I know none of you pay attention to the blog of at the Society for Science-Based Medicine and I have no time with work and the holidays to come up with new material, I am going to collect and expand on the entries on acupuncture I wrote from SfSBM. Anything I write really is worth reading twice. I really need to make my multiple personality disorder work for me, but the Goth cowgirl persona is a luddite at best, so you are stuck with the over -extended ID doctor. Here goes.
A recent study in the Journal of General Internal Medicine evaluated a treatment for constipation. It tested whether training patients to massage the perineum (the area between the vagina or scrotum and the anus) would improve their reported bowel function and quality of life at 4 weeks after training. They found that it did. It’s a simple, innocuous treatment that may be worth trying, but why, oh why, did they have to call it “acupressure”? That irritated me. Should it have? Why should it matter? Isn’t a rose by any other name still a rose? Is this a meaningless semantic quibble and hypersensitivity on my part, or am I right to see it as yet another example of quackademia’s attempts to infiltrate science-based medicine? I’ll explain my thinking and let you decide for yourself. (more…)
