Railgun patient launcher Magnetic resonance imaging machine, not a useful tool in identifying the cause of back pain
The ads in my local newspaper are a never-ending source of questionable health claims, most often from diet supplement manufacturers and chiropractors. There’s no single spokesman like Dr. Oz, but as a group they remind me of Oz’s unending series of weight loss miracles, each one the perfect solution until the next one comes along. The proliferation of chiropractic ads is bad advertising for the efficacy of chiropractic itself, since chiropractors are increasingly turning to adjunctive treatments like lasers and decompression machines.
The latest ad that annoyed me was from the Objective Diagnostics Research and Rehabilitation Institute (ODRRI). What an impressive name! On their website, not only do they advertise “the low back pain solution,” but they offer to fix herniated discs without surgery. They say they treat the underlying cause and say their approach is “based on solid and leading edge diagnostics, scientific research, and experience.” While not a complete lie, that statement is certainly misleading.

The saga of chiropractic began in 1895 when D.D. Palmer, a magnetic healer, announced that “95 percent of all diseases are caused by displaced vertebrae, the remainder by luxations of other joints.” Palmer opened the first chiropractic school in Davenport, Iowa, offering a three-week course of study at the Palmer School and Cure, subsequently renamed the Palmer School of Chiropractic. The school was taken over by B.J. Palmer, the son of D.D. Palmer, in 1906. In 1910, the course of instruction was six months. Kansas and North Dakota were the first states to pass laws legalizing the practice of chiropractic (in 1913 and 1915). By 1921, the Palmer School of Chiropractic, requiring 18 months of study, had 2,000 students, reaching a peak enrollment of 3,600 in 1922. By 1923, 27 states had chiropractic licensing boards. Hundreds of chiropractic schools sprang up, some offering correspondence courses. There were no entrance requirements, anyone could become a chiropractor. H.L. Mencken wrote in the December 11th, 1924, issue of the Baltimore Evening Sun:
Today the backwoods swarm with chiropractors, and in most States they have been able to exert enough pressure on the rural politicians to get themselves licensed. Any lout with strong hands and arms is perfectly equipped to become a chiropractor. No education beyond the elements is necessary.1
Although Palmer’s subluxation theory was contrary to all known laws of anatomy and physiology, the theory was appealing to the general public. Medical science was in its infancy, struggling to find effective and safe remedies for disease and infection. There was no known cure for many common ailments, and many of the medicines used by physicians were ineffective or harmful. In the public marketplace, the door was wide open for snake oil salesmen, entrepreneurs, and opportunists who could mix a concoction or fabricate a new treatment guaranteed to work. With growing numbers of chiropractors treating disease and infection by adjusting the spine to relieve alleged pressure on spinal nerves, offering treatment claimed to be superior to medical care, members of the medical community felt an obligation to oppose what they viewed to be blatant, unbridled quackery.

I am often asked, “What do chiropractors do?” That’s not an easy question to answer. The answer is usually expected to be, “They treat back trouble.” But as alternative medicine practitioners, chiropractors do a lot of things, and they treat a variety of ailments, based largely on a scientifically-invalid vertebral subluxation theory which proposes that nerve interference resulting from a misaligned vertebra or a dysfunctional spinal segment can affect general health.
As a co-host of the Chirobase web site, I frequently answer questions about chiropractic, some of which are published in a section titled “Consumer Strategy/Consumer Protection.” In this post, I’ll focus on these:
- Are Subluxations Causing My Health Problems?
- Is a Misaligned Atlas Causing My Back Pain?
- What is that “Thumper” My Chiropractor Uses on My Back?
- How Does a Chiropractor Locate Subluxations?
- Should I Let a Chiropractor Adjust My Baby?
- Why Is Every Chiropractor’s Treatment Different?
- Can Neck Manipulation Cause a Stroke?
- Should I Go to a Chiropractic College?
- Are There Any Good Chiropractors?
- Is It Possible to Reform the Chiropractic Profession?
By far, most of the questions I receive express concern about questionable methods and advice offered in the offices of chiropractors. Many questions are generated by the suspicions of patients who initially visited a chiropractor for treatment of back pain and who were then offered spinal adjustments as a treatment for health problems unrelated to the spine. Patients are often concerned about the expense involved in such care, usually extended over a long period of time, followed by “maintenance care” to correct or prevent “vertebral subluxations” after symptoms have resolved. I generally advise patients to refuse chiropractic care for anything other than a musculoskeletal problem, to seek treatment only when symptoms are present, never pay for treatment in advance, and to discontinue treatment and see an orthopedic specialist if symptoms worsen after a few days or have not subsided after a week or so.
Although obscured by controversy, there is evidence to indicate that spinal manipulation can be as effective as conventional treatment methods in relieving low-back pain.1,2,3,4 This grain of truth mixed with chiropractic vertebral subluxation theory that encompasses a broad scope of ailments makes it difficult for the average person to distinguish between appropriate and inappropriate use of manipulation by chiropractors. A person who is satisfied with chiropractic manipulative treatment for back pain might be led to believe that the same treatment can be used to treat a variety of organic ailments by correcting “vertebral subluxations.” Such treatment is usually described as a “chiropractic adjustment.”
A manual chiropractic adjustment
Although chiropractic care based on subluxation theory has been rejected by the scientific community, spinal manipulation used in the treatment of mechanical-type back pain has a plausible basis that makes it acceptable in mainstream healthcare. A good back-cracking back rub provided by a chiropractor or some other manual therapist can be a pleasurable, pain-relieving experience, and this can be a preferred method of treatment for some types of back pain. But you should be well-informed enough to know where to draw the line in separating subluxation-based chiropractic adjustments from appropriate use of generic spinal manipulation if you should consider treatment by a chiropractor. Otherwise, you might become the victim of the bait-and-switch tactics of chiropractors who offer you treatment for back pain and then attempt to indoctrinate you in subluxation theory.
Much of what follows in this article has been said before in other articles of mine posted on this site. An up-to-date summary of basic concerns about chiropractic care, however, might be useful for new readers and others, including professionals, who want a brief overview for quick reference in seeking answers to questions about the problematic aspects of chiropractic use of spinal manipulation.
Low back pain is a particularly frustrating condition that is common, poorly understood, and difficult to treat. Could a long course of antibiotics be the answer for some patients? A recent study from Denmark suggests that it might be: “Antibiotic treatment in patients with chronic low back pain and vertebral bone edema (Modic type 1 changes): a double-blind randomized clinical controlled trial of efficacy” by Albert, Sorensen, Christensen and Manniche. Is this a crazy idea like long-term antibiotics for “chronic Lyme disease” or will it pan out like antibiotic eradication of H. pylori in patients with ulcers? Time will tell. This was a rigorous, well-done study, but we can never rely on the results of a single study until it is replicated or confirmed elsewhere.
Glucosamine is widely used for osteoarthritis pain. It is not as impossible as homeopathy, but its rationale is improbable. As I explained in a previous post,
Wallace Sampson, one of the other authors of this blog, has pointed out that the amount of glucosamine in the typical supplement dose is on the order of 1/1000th to 1/10,000th of the available glucosamine in the body, most of which is produced by the body itself. He says, “Glucosamine is not an essential nutrient like a vitamin or an essential amino acid, for which small amounts make a large difference. How much difference could that small additional amount make? If glucosamine or chondroitin worked, this would be a medical first and worthy of a Nobel. It probably cannot work.”
Nevertheless, glucosamine (alone or with chondroitin) is widely used, and there are some supporting studies. But they are trumped by a number of well-designed studies that show it works no better than placebo, as well as a study showing that patients who had allegedly responded to glucosamine couldn’t tell the difference when their pills were replaced with placebos. The GAIT trial was a large, well-designed, multicenter study published in The New England Journal of Medicine that showed no effect in knee osteoarthritis. A subsequent study of hip osteoarthritis also showed it worked no better than placebo.
A new study shows that glucosamine works no better than placebo for osteoarthritis pain in the low back. It was published in the JAMA: Effect of Glucosamine on Pain-Related Disability in Patients with Chronic Low Back Pain and Degenerative Lumbar Osteoarthritis: A Randomized Controlled Trial, by Wilkens et al.

In September 2008 I wrote a post on Misleading Ads for Back Pain Treatment. with particular attention to the bogus claims for the DRX 9000.
The Canadian Broadcasting Company (CBC) show “Marketplace” has just done a scathing exposé of so-called nonsurgical spinal decompression treatment with machines like the DRX 9000 and of some of the unscrupulous practitioners who offer it. Between the hidden camera footage and the weasel words of the chiropractor they interview, it’s quite entertaining.
There was a full-page ad in my local paper today for Back in Action Spine and Health Centers, targeted at sufferers from almost any kind of chronic back pain. It started with “Are You Ready to Throw in the Towel and Just Live with Hurting So Bad?” It went on to make a number of claims:
- Doctors can fix the problem.
- Breakthrough medical technologies.
- Treatments are FDA cleared.
- Treatments are scientifically proven.
- No side effects.
- Best kept secrets for healing “bad backs.”
- Corrects scoliosis.
- Corrects compressed discs.
- Several university studies at Johns Hopkins, Stanford and Duke have confirmed that these treatments work.
- Medical researchers have reported these methods up to 89% effective.
- Treatments work for back and neck pain, sciatica/numbness, herniated and/or bulging discs, degenerative disc disease (arthritis), spinal stenosis, facet syndromes, spondylolisthesis.
- Their questionnaire can determine who will benefit – if you fit even one criterion like “does your back feel out of alignment?” or “do you have arthritis?” you should call right away.
The ad offers a “Free Qualifying Exam” but you “Must Not Wait” because appointments are limited and they can only honor this free offer for 3 weeks. To encourage you to call, they sweeten the pot with a FREE $49 gift bag.
Are you suspicious yet? You should be. (more…)
