|Poisoned by Massage+
Massage is not a detoxification treatment in any sense, contrary to a popular belief. Ironically, it’s the opposite: post-massage soreness and malaise (PMSM) is probably caused by mild rhabdomyolysis (“rhabdo”). True rhabdo is a medical emergency in which the kidneys are poisoned by myoglobin from muscle crush injuries. But many physical and metabolic stresses cause milder rhabdo-like states — even just intense exercise can do it, and probably massage as well. This is substantiated by a case study of acute rhabdomyolsis caused by intense massage (see Lai), by many well-documented cases of exertional or “white collar” rhabdo, and by the strong similarity between PMSM and ordinary exercise soreness. A rhabdo cocktail of waste metabolites and by-products of tissue damage is probably why we feel a bit cruddy after biological stresses and traumas — even massage, sometimes. And you can’t “flush” the rhabdo away with massage or by drinking a little extra water. PMSM is just an unavoidable mild side effect of strong massage.Rather than being “detoxifying,” massage may cause a modestly toxic situation in the body

|Digital Motion X-Ray+
Digital motion X-ray (DMX) is an X-ray video: many X-ray images strung together to make a movie. The output is impressive. In theory, it can reveal serious problems that somehow eluded diagnosis otherwise. In practice, this unregulated and banned-in-Canada technology is primarily sold to neck pain patients by chiropractors, often for evidence in personal injury lawsuits, and is completely eschewed in medicine because of concern about radiation exposure. DMX undoubtedly has some potential to show important things, but is it worth an increased risk of cancer to diagnose conditions that, mostly, can and should be diagnosed any other way? It’s not completely out of the question, but you should get multiple medical opinions and think hard before resorting to this exotic diagnostic method.What’s the risk from the radiation exposure?

|Your Back Is Not “Out” and Your Leg Length is Fine+
“Structuralism” is the excessive focus in the physical therapies on crookedness or “mechanical” problems in the body — what I call the biomechanical bogeymen. It is the source of much bogus diagnosis — things like tilted pelvises, short legs, abnormal spinal curvatures, or “misaligned” anything — and the cause of much therapeutic barking up the wrong tree. Such factors are much less important than many people still believe.
Structuralism has been challenged by many medical researchers and experts like Dr. Lorimer Moseley Moseley, Dr. Scott Dye (knee surgeon); or back experts Drs. Richard Deyo, John Sarno, and Nickolai Bogduk; soft tissue pain experts like the late Dr. Janet Travell, Drs. David Simons and Seigfried Mense (see Muscle Pain), or Dr. Chann Gunn, and on and on.
Many key scientific studies over the years have undermined major structuralist assumptions, like Finan’s finding that knee pain correlates more with pain sensitivity than arthritis; Grundy’s conclusion in Lancet that short leg length differences don’t correlate with back pain; or Grob’s findings that abnormal neck curvatures do not predict neck pain; or Moseley’s finding that a placebo for knee osteoarthritis is just as good as real surgery; or numerous MRI studies showing terrible correlation between structural problems and back pain (see Boden, Jensen, Weishaupt, Stadnik, Borenstein); or the astonishing finding by Haig that even narrowing of the spinal canal does not necessarily cause stenotic back pain; or the clear evidence that even dislocation of the upper cervical spine is often asymptomatic (Swinkels); and so on (and on and on).Debunking the obsession with alignment, posture, and other biomechanical factors as a major cause of pain

|Quite a Stretch+Stretching just doesn’t have the effects that most people hope it does. Plentiful recent stretching research has shown that it doesn’t warm you up, prevent soreness or injury, enhance peformance, or physically change muscles. Although it can boost flexibility, the value of this is unclear, and no other measurable and significant benefit to stretching has ever been proven. Regardless of efficacy, stretching is inefficient, “proper” technique is controversial at best, and many key muscles are actually biomechanically impossible to stretch — like most of the quadriceps group (which runners never believe without diagrams). If there’s any hope for stretching, it might be a therapeutic effect on muscle “knots” (myofascial trigger points), but even that theory is full of problems.

|Does Spinal Manipulative Therapy (SMT) Work?+
The idea of “adjusting” the spine refers to many different manual therapies that wiggle, pop and otherwise manipulate spinal joints. The correct umbrella term for these treatments is “spinal manipulative therapy” or SMT. Expert opinions on SMT range widely, with some prominent medical scientists expressing strong concern and skepticism. Its provenance in chiropractic subluxation theory is dubious, its benefits are minor at best, and yet there are serious risks, even including paralysis and death in the case of SMT for the joints of the neck.
Despite all the controversy, there has been little high quality scientific research to determine whether or not SMT is safe and really works. Major science reviews have either been thoroughly discouraging. Thus, SMT fails the “impress me” test — it can’t possibly be working any miracles.
And yet spinal joint popping in particular is something that people crave, and most clinicians believe that some forms of SMT can be helpful to some of their patients, some of the time. There seems to be almost no doubt that there is something of therapeutic interest going on in SMT, at least some of the time.Adjustment, manipulation, and popping of the spinal joints and the subluxation theory of disease, back pain and neck pain

Surprisingly, Frobell et al found that it’s not clear if a torn anterior cruciate ligament should be surgically repaired. In a randomized, controlled study of 121 young adults with acute ACL injury, there was little difference between getting reconstructive surgery right away and just doing normal rehabilitation. Given the structural importance of the ACL ligament, it’s amazing that it can recover from major trauma without surgery approximately as well as it can without. This study did not show that ACL repair is never or rarely necessary, but it certainly strongly suggests that it’s less crucial than most people would expect.

For many people, a diligent effort over a period of weeks might well increase your range of motion. In 2011, a nicely done experiment by Marshall et al showed that regular hamstring stretching substantially increased range of motion in normal university kids. Specifically, after “a 4-week stretching program consisting of 4 hamstring and hip stretches performed 5 times per week,” their range increased about 16˚ or 20%. That’s a real result. For whatever it’s worth. Regardless of what it does for flexibility, stretching remains amazingly useless for nearly any other popular or clinical goal. See Quite a Stretch.

The introduction is now available on my sleepy little personal blog, Writerly, and the first dozen chapters are queued up — they’ll be freely available while I finish writing the book.

|blogTwo books edited, six to go+ |
I’m pleased to announce the first complete professional editing of two of my books — about plantar fasciitis and iliotibial band syndrome. Although the difference will not be obvious to most readers, several hundred improvements and corrections were made to each, and the reading is definitely smoother.
What took me so long? Logistics and cash. Like any truly professional writer, I always knew I needed good editorial help, but that can be hard to find and pay for. Editing a book is a Big Deal. But SaveYourself.ca has grown to the point where it finally got important and affordable, and I was lucky enough to find a skilled, reliable editor: JoAnne Dyer of Seven Madronas Communications. After working with JoAnne on many smaller projects over the last couple years, I asked her to start working on my books. Two down, six to go!

|blogSo…what does work, Mister Smartypants?+ |
I am often criticized for failing to suggest alternatives when criticizing bad ideas in therapy, especially in my article about “structuralism” (overemphasizing biomechanical factors in therapy). It’s a bogus gripe: failing to suggest a wardrobe for the emperor to wear tomorrow doesn’t make him any less naked today. Structuralism is a deeply flawed basis for therapy regardless of whether anything can readily replace it. But I’ve gone ahead and made some simple suggestions anyway, in a short new conclusion to the article (link takes you directly to the conclusion).
There will be much more on this so-what-does-work theme over the next couple years. I’m just getting started on it.

|blogOh, stretching! Can you do anything right?+ |
My main stretching article now includes a section on the failure to treat contracture (a scar-like shortening of soft tissues). Stretching always gets the benefit of the doubt, whether it deserves it or not. Most people and most professionals probably assume that long, intense stretches are an effective prevention/treatment for contracture. It is not an assumption held with much conviction, I imagine — it’s just that stretching always gets the benefit of the doubt, whether it deserves it or not, and it seems to “make sense” that stretching would be a cure for contracture.
Common sense fails again, I’m afraid. Continue reading (link goes directly the new section).

Can a custom shoe prevent injuries by compensating for individual differences in running mechanics?
Knapick et al. gave several hundred Marine Corps recruits motion control, stability, or cushioned shoes for their “low, medium, or high arches.” Those recruits got injured just as much as hundreds of other recruits who were given stability shoes, regardless of their arch shape. It’s a large, good quality experiment that clearly establishes that prescribing special shoes “based on the shape of the plantar foot surface had little influence on injuries.” What “Big Ortho” doesn’t want you to know!

Not many self-help books go to great lengths to stifle false hope and unrealistic expectations…but mine do. My shin splints book is not intended to “decrease shin pain,” and I warn readers about that, in several ways, in both the free introduction and in the main text. In fact, I would say it’s impossible to actually read and understand my book and still think that it should have “fixed” anything. It’s an unreasonable expectation of any book… but particularly one that goes well out of its way to caution readers against that expectation!

|Trigger Point Doubts+
People routinely experience muscle pain and acutely sensitive spots in muscle tissue — “muscle knots.” They can be surprisingly severe, and massaging them often seems to help quite a bit. What’s going on? The dominant theory is that a trigger point is a patch of tightly contracted muscle, an isolated spasm affecting just a small patch of muscle tissue. Unfortunately, after a few decades it’s still just a theory, and trigger point science is a bit half-baked and somewhat controversial. It’s not even clear that there is really a problem in the meat at all; it could be a sensory “disturbance,” for instance. Meanwhile, people keep hurting, and there is little doubt that there is an important, almost epidemic phenomenon here in need of explaining and treating. Massage — especially self-massage — remains a safe, cheap way of trying to deal with it, and there is some evidence that it can provide some meaningful relief (e.g. Furlan 2008) is probably the best example). That’s why I have a large tutorial devoted to how to self-treat “trigger points” — whatever they really are. But it’s very important to keep in mind that they are not well understood.Is there really such a thing as a muscle “knot”?

|Does Ultrasound Work?+
Ultrasound therapy is the use of sound waves to treat musculoskeletal problems, especially inflammation (tendinitis, bursitis). It has been a popular therapy for decades, its use so widespread that it almost defines physical therapy. Unfortunately, although mainstream, it is not as scientific a treatment as most people assume. It has been generally undermined or damned with faint praise by one scientific review after another for more than a decade now. Between 1995 and 2008, what little science has been done on the subject was reviewed in ten papers I considered to be worthwhile (see Gam, Windt, Brosseau, Robertson, Welch, Baker, Buchbinder, Ho, Ho, Jamtvedt). Eight of those were unambiguously negative, some of them strongly so. Authors had almost nothing good to say about ultrasound. Conclusions like this one (from Windt et al) are the rule: “As yet, there seems to be little evidence to support the use of ultrasound therapy in the treatment of musculoskeletal disorders.” Some modern variants of ultrasound are expensive, hyped, and totally unproven for any or many conditions.Many concerns about the widespread usage of therapeutic ultrasound, especially extracorporeal shockwave therapy (ESWT)

|Does Fascia Matter?+
Fascia is widely regarded as an exciting scientific frontier, with well-attended fascia conferences featuring “rock star” gurus in the world of massage and manual therapy. The main idea is that fascia — tough connective tissue wrapping around all muscles and organs — can get tight and restrictive, and needs to be “released” by pulling on it artfully. Unfortunately, although fascia science may be inherently interesting as biology, and fascial compartment syndrome is certainly a real and scary medical problem, no subtle property of fascia has yet been shown to be clinically relevant. No fascial pathology seems to be a factor in any common painful problem, and no method of fascial manipulation is known to “fix” fascia or even change it.
I have challenged fascia fans to cite clinically relevant fascia science, with no result years now. This article reviews three key candidates: well-known studies about fascia’s toughness, its contractility, and its fibroblasts. None confirm any clinical relevance of fascia, and one actually undermines it, showing that fascia is too tough to “release.” I also discuss the irrelevance of piezoelectricity, thixotropic effect, and contradict Gil Hedley’s popular fascial “fuzz” theory of stiffness. The article criticizes fascia excitement from a scientific perspective.A detailed critical analysis of the clinical relevance of fascia science and fascia properties

|Tissue Provocation Therapies+
"There are two “laws” of tissue adaptation, one each for hard and soft tissue. Wolff’s law is that bone will change and strengthen in response to loading. This was first noticed by Julius Wolff in the 19th Century, who got the naming rights. It was greatly refined in the mid 20th century by Dr. Harold Frost, an American surgeon who studied bone biology, and published scientific papers more often than I change my socks. The full details of how bone responds to stress are described in his Mechanostat model. The corollary in soft tissue is the obscure and much less developed Davis’ law. (No one even seems to know who Davis was.)
Although there’s no question soft tissue does adapt to stress, the responses of muscles, tendons, and ligaments are much more complex and less well understood. Many treatments are based on the idea of forcing adaptation or “toughening up” tissues by stressing the tissues. It has always been a reasonable idea, but the devil is in the details: what constitutes the “right” amount and kind of stress is difficult to know, and the results of such therapies have generally been highly inconsistent.The laws of tissue adaptation and provocation therapies like Prolotherapy and Graston Technique

|The View from Somewhere+
Readers often prevail upon me to be “objective,” but it’s an over-rated virtue. I am often criticized for a lack of it — always by somone who disagrees with me. And sometimes I am praised for my neutrality — always by someone who agrees with me. But I am not impartial on any of the controversial questions in my field, I’ve never met anyone who is, and I don’t aspire to it.
Objectivity and balance are highly over-rated as journalistic virtues. They are mostly a pretentious delusion, and you should actually beware of those who claim to have them. See Jay Rosen on “the view from nowhere.” And Dan Rather said it well: “I don’t like the word ‘balance’ as applied to journalistic work, because to me, that carries with it at least a connotation that, if you run 15 words about the Republican Party, then you’ve got to run 15 words about the Democratic Party. That’s balance. But I think “fairness” is the word I prefer” (interviewed by Hedrick Smith on PBS, 1996).
Instead of expecting balance, look for someone with a View from Somewhere — from someone who isn’t afraid to disclose and own a bias. That is my goal. Not only will I fail to achieve the ideal of “objectivity,” I assume that my biases are inevitable, constantly egregious, and utterly human. We are all bias machines. We can only keep a bemused eye on this frailty, do some damage control, and try to avoid being emphatic or overconfident about much of anything other than the rise of the sun, death, taxes, and the absurd fallibility of confidence itself. The ideal is not be unbiased, but to be biased with integrity.

Most therapeutic taping is either practical (stabilizing a sprained ankle), or aims to tinker with more subtle biomechanics. Taping has gotten a lot hotter in the last few years with prominent new products and branding, and lots of hype and claims about therapeutic effects, prevention, and performance enhancement. New materials that may achieve different and possibly superior benefits, but probably not much. It doesn’t work biomechanically, as many professionals assume. It’s more likely that the odd sensations change function and reduce pain, but that kind of effect tends to be minimal, and hard to predict and control.Over-hyped, but harmless and at least a little bit promising

|Fatigue-induced muscle rippling+
Muscle fibres do not normally contract all at once, as most people imagine. Instead they are organized into groups called “motor units,” one per motor nerve. Rather than firing all at once, the groups alternate their contractions, like pistons. At any given time, countless motor units are in different phases of contraction and relaxation. The units are so small and the switching system is so fast that their coordinated action seems to be completely smooth to us.
There is an interesting exception, though: if you get tired enough that a lot of motor units start failing to contract, the switching system fails because there aren’t enough motor units available for smooth contraction. This is why muscles start to ripple and quiver with very intense exertions.
This phenomenon has no official name that I know of. It is sometimes called “fasciculation,” and I used to do that myself, but it’s an error: that’s just the smartypants word for an involuntary contraction, a twitch or spasm. This rippling business happens in a resting muscle as well a contracting one.

Once again, consider the case of Philippe Fuchs, who ran from Paris to Beijing, covering ~5,100 miles in 161 days. His primary concern was his “ability to keep absorbing muscular and skeletal punishment day after week after month,” of course. By the time Fuchs finished, he had developed an endurance stride that was clearly shorter and lower: he padded along with about 6% more steps per mile, a whopping 30% less time in the air, and 11% less landing force. I’m betting he wouldn’t have made it without those adjustments. Fascinating!

new article about Kinesio Tape® and similar products, which explains that therapeutic taping is mainly just a sensation tweaker, and that’s fine as far as it goes. We humans are neurological input-output machines. We constantly, systematically, creatively tinker with how we feel … touch-testing the world. This is why I have no strong objection to therapeutic taping, but also why I will probably never be impressed by it: it’s just another method of playing with how our bodies feel, one of many. But it will never trump functional challenges as the main drivers of recovery and performance. The bottom line is always going to be that we have to push ourselves a little to get better than we are — and being taped just isn’t much of a challenge.

|blogPerformance enhancement+ |
“Performance enhancement” is usually a problematic claim, because it’s commonly based on sloppy extrapolation from recovery effects (which are themselves often a bit sketchy). Even what genuinely helps people who are sick or broke is not necessarily going to do anything for fit, healthy people. Or vice versa. (Simple example: compression bandaging for swelling. Unambiguously handy in recovery … but useless if you’re not swollen!) Rehabilitation and performance enhancement are just different things. On the one hand, they are the same process with different starting points. On the other hand, how much value the body can extract from an input is generally proportionate to need. A glass of water is more important to a man dying of thirst, and novel sensation is more neurologically useful to an injured person than a healthy Olympian.

It is a widely and passionately held belief that back and abdominal strengthening will help back pain, and Pilates is the branded exercise system dedicated to core strengthening, so Pilates must be good for back pain, right? But in a recent test by Miyamoto et al, patients who did Pilates had “small benefits” compared to those who did not. And the test had a serious flaw: it neglected to compare Pilates to other any other kind of activity (shamefully sloppy design, fairly junky science). These results only add to the pile of evidence that exercise and therapeutic attention of any kind are probably good for low back pain. It’s only worth reporting these results insofar as they damn Pilates with the faintest possible praise — evidence that Pilates has no special power over back pain. I am not even a tiny bit surprised by this.

Because, of course, what we see in magazines and movies aren’t really people anymore, but skilfully lit and pixel-manipulated artwork — beautiful in their own way, of course, or why bother? But they are only distant, abstract cousins to homo sapiens. In all my years massaging, I never experienced a client as “ugly.” It just isn’t possible when you’re actually paying attention to the person.

|blogWeights as good as a run?+ |
What if it was just as good for your aerobic fitness to lift weights as to run? Here’s a paper that says it probably is. The authors have a bias favouring this theory, and there’s no real evidence about it yet, but it’s plausible and they make several perfectly reasonable points about the basic exercise biology. At the very least, it does firmly support the idea that building strength is better for general fitness than most people realize (which is all I’m really after). More detail in the bibliography:

Real question from a runner:
Um, no … in (at least) 2 important ways:
First, of course, there’s just a real risk of making any injury much worse that way. Duh! There are exceptions, but you need to know what those are — you need a clear and specific rationale for breaking a generally excellent rule.
And second, “stuffing” with pain-killers is seriously risky and useless to boot. Pain-killers are bandaids at best, possibly not even that, and definitely not a good long term solution, because there isn't a single one that doesn't have truly serious hazards with chronic use (not the least of which is their effectiveness wanes).

Critical what? Hardly a day goes by I don’t read something smart online about critical thinking: how important it is, how to do it. It’s everywhere. So … why is still so much not-so-critical thinking floating around out there?! It seems odd.
The answers are obvious of course: above all, good quality thinking is a skill, because it requires working around obstacles that are truly unknown to us without training (obscure logical fallacies and sneaky cognitive distortions). It’s a hard skill to learn even for people who are super motivated. There’s almost no chance if it threatens comforting beliefs… or, worse, the basis for making a living!
But it still seems mighty peculiar and ironic that there’s so much good information available about critical thinking that isn’t being used.

Noise, noise, noise! I am often asked about the meaning of knee noise (“crepitus”), which can often be quite spectacular — surely the loudest joint in the body. But knee noise in the absence of any other clear signs (like pain) is usually uninterpretable. It does not correlate well with problems. So you can be in trouble ... silently. And you can be fine... noisily. Rule of thumb: crepitus is only of concern if you’re also in pain, and not necessarily even then.

Why is back pain still a huge problem? Here’s an articulate explanation from a new paper by Max Zusman:
Nicely said. More simply: patients believe back pain is caused by structural fragility, and therapy careers are often built on catering to that belief.
If only I could edit it, though, I would say instead that it is difficult to alter that belief in anyone, patient or professional. The overemphasis on fragility isn’t just reinforced by the practices of manual therapists, it’s the reason for many of them.

But derpish stupidity is also rampant in health care, and this more technical definition of what derp has come to mean in politics is a pitch perfect description of how quacks defend their beliefs — namely, with self-serving assumptions that are impervious to contrary data, and are literally decades or even centuries behind biology and medicine.

|blogFailed healing+ |
Most of the time it’s hard not to heal. You couldn’t stop it if you tried — not that you’d want to. The body is going to recover from most kinds of injuries almost no matter what — it’s just a matter of time. As long as you were reasonably healthy before you were injured (and you don’t smoke or otherwise abuse your vitality), healing will usually progress inexorably.
Chronic pain is different by definition: it doesn’t stop when it’s supposed to. Either healing itself fails, or the pain continues even when the tissues are fine, or a bit of both. Overuse injuries or repetitive strain injuries (RSIs) like carpal tunnel syndrome and plantar fasciitis are slow-motion traumas that often seem immune to recovery — this is what makes them both terrible and fascinating. They are not as simple as they seem. More:

|Jun 4, 13Jun '13||15||•|
Therapeutic touch (TT) is hands-off aura massage, actual touch not included, and it is the most common form of energy or chi medicine. Many years ago I believed in it, but that’s true of Santa Claus too; eventually I decided it was nonsense based only on wishful thinking, laughably naive references to quantum physics, and wide-eyed exaggeration of ordinary social interaction effects. Most practitioners are massage therapists and, oddly, nurses. TT is a culturally neutral subset of Japanese reiki, which has been successfully exported around the world. (Reiki practitioners have the infamously obnoxious holier-than-thou habit of calling themselves “masters.” •eyeroll•)
Auras do not exist and cannot be felt, let alone manipulated therapeutically. Just as dousers and psychics have never passed a controlled test, TT practitioners cannot not detect a person by feeling their aura (see Rosa et al), which makes them look ridiculous.
It is peculiar and pleasant to have someone wave their hands all around you with friendly intentions, but those effects are minor and fleeting and it doesn’t matter what specifically the therapist does, because it’s the interaction that is the active ingredient. (Hence the term “non-specific effects,” a cousin of placebo.) There’s no problem with doing therapy in a way that optimizes non-specific benefits, but it has strict limits. Placebo is nowhere near as “powerful” as people believe (usually for self-serving reasons), and there are all kinds of ethical and practical problems with cluttering up the interaction with interpretations of what’s going on.

Everyone should know better than to trust those stories — because it’s 2013, not 1913 — but they are still prevalent, given far too much weight, and they hijack most conversations about what works and what doesn’t for stubborn painful problems. As soon as someone says, “Well, it works for me/my patients,” that’s pretty much the end of any useful debate.

|Applied Kinesiology is Bunk+
Applied kinesiology (AK) is a pseudoscientific method of diagnosis and prescription, used by many chiropractors and naturopaths, and denounced as an absurd parlour trick by everyone else. (AK has no relationship to kinesiology, which is the study of human movement.) Practitioners believe that muscle strength fluctuates meaningfully and is a useful diagnostic tool. They test strength while substances are placed on or near patients, or while asking meaningful questions: strength means the body says yes, weakness means no. This is about as scientific as a ouija board.
There is almost no real AK research: no real scientist would bother with it, or get funding for it. It’s like studying the Nigerian email scam to see if it really works. Even NCCAM hasn’t bothered (NCCAM exists to study alternative medicine).
Patients are often impressed by AK, because it exploits potent illusions based on the ideomotor and observer-expectancy or subject-expectancy (power of suggestion) effects. This is why a magician like James Randi knows exactly how to debunk AK (see also a more detailed video debunking). It fools practitioners just as readily as it fools patients: most are deluded true believers, not scam artists.

Thursday and Friday’s trouble with my e-bookstore now seems to be cleared up, but it took a solid 48 hours.

The theory is that corrected information about the location of my e-bookstore took much longer (2 days) to spread around the world than it would have before (2 hours).

This is great! A nicely written reality check on the antibiotics for back pain hype, from PubMed. Great stuff.
Back pain is one of the richest myth mines in all of medicine. An extremely common, often serious, and usually mysterious pain problem = absolutely maximum fertility for bullshit to grow in. There are a great many books about low back pain, and many are garbage, selling snake oil and hype and false hope instead of good information. There are also some fine myth-busting books about low back pain … and mine is one of them.

“Modality empire” is my own term for an ego-driven proprietary method or mode of manual therapy — a sub-discipline — championed and promoted by a single charismatic entrepreneur. Most of the “emperors” have healer syndrome, lack humility, make big promises, and make their money from unusually expensive therapy, workshops and books. Professionals are sold on the opportunity to purchase credibility in the form of increasing “levels” of certification, but the quality of these certifications is completely unregulated and often dubious. A modality empire is as much a business model as a method of helping people. There is a lot of overlap between modality empires and quackery. Classic examples of modality empires include Ida Rolf’s ROLFING®, John Barne’s myofascial release, and John Upledger’s craniosacral therapy. Sometimes a modality empire is particularly unoriginal, re-packaging old ideas for a new generation of workshop consumers.A tradition of ego-driven treatment methods in manual therapy

Interesting, impressive new work announced today by Examine.com: a well-crafted new presentation of a huge database of scientific evidence that “clearly tells you what a supplement does (and doesn’t do). Goodbye supplement confusion.” This rabbit hole goes deep, so browse. Look at their “Human Effect Matrix” tables for key topics in particular, which beautifully summarize the science (go right to an example, for creatine). What’s remarkable here is the quality of the presentation. These are not just tables of data! They are quite artful, crafted to emphasize what matters. I would love to have evidence presented like this on SaveYourself.ca, and I do have some of the foundations for it — but I’m a few design and technology leaps away from being able to deliver something like that.

Patients with back pain and sciatica recovered about equally well with or without disc herniations visible on MRI. Most people recovered (84%) well within a year … and there were actually 2% more good outcomes in the patients with disc herniations! This seems like a rather surprising result, but that is what the research has been showing for years. There is a chance the nearly identical stats are a fluke, but they’d have to be off by a lot to change the take-home message. Even a 20-point difference, ten times larger than this, would still show that a “slipped disc” confirmed by MRI isn’t nearly as worrisome as most people assume.

It’s a topical anti-inflammatory medication, so it can be applied only where you need it, instead of soaking your entire system with medication, avoiding or minimizing common side effects like indigestion, and some serious safety concerns associated with the oral version of the drug. It’s FDA-approved to treat osteoarthritis in “joints amenable to topical treatment, such as the knees and those of the hands,” but it probably also works for some other painful problems, such as some repetitive strain injuries and back pain. The evidence shows that it “provides clinically meaningful analgesia.” So this product actually works and it gets a pass from skeptics and critics — a rare thing indeed in the world of pain treatments!

It doesn’t take much reading at TestingTreatments.org (see previous post) to realize that it’s actually impossible to know if a something works based on clinical observations alone. Repeat after me:
“I will not claim to know what treatments really work for pain before they are properly tested.”

|blogOne of my favourite history of medicine stories+ |
It’s the 200th birthday of John Snow, the father of epidemiology, the science of diseases and how they spread. In 1854, Snow mapped cases of cholera and traced the disease to its origin, and proved with a simple test that it was coming from a polluted well: he removed the pump handle, and the cholera outbreak stopped. Naturally, this conclusion was scoffed at by those with competing theories (“bad air”), producing one of my favourite history of medicine stories: to prove that cholera was not in the water, some smartypants biologist drank a glass of the stuff … and got away with it, because he just happened to be immune. It’s a great example of why “experience” is not trustworthy, and why it takes so long to settle even relatively straightforward puzzles in medicine.

Pelvic tilt is one of the great biomechanical bogeymen, one of those things that gets blamed for a lot of pain and is the justification for a lot of massage and chiropractic therapy. I was taught in school to judge pelvic tilt by measuring the pointy bits. It all seemed very technical. And yet, as I always suspected, pelvic shape is simply much too variable to diagnose pelvic tilt by feel. The shape can vary as much as the position! A new study of cadavers “found that the PSIS/ASIS angle varied from left to right (up to eleven degrees), even when the pelvis was in neutral. The asymmetrical shape of the pelvis in this respect could make it appear that one side is rotated forward compared to the other.” That’s from a superb report on the study by Todd Hargrove at BetterMovement.org:

|Thixotropy is Nifty, but It’s Not Therapy+Thixotropy is the property of some gels or fluids that are normally thick (viscous), but thin when they are stressed. In the human body, the synovial fluid that lubricates most joints is thixotropic, as is the gelatinous “ground substance,” which is part of all connective tissues such as tendons and ligaments. (Fun fact: semen is also thixotropic.) Thixotropy is one of the reasons that we loosen up a little as we move around, just like engine oil warming up. However, thixotropic effect is not a therapeutic effect, and does not explain “releases” in massage or fascial therapy: it is too minor, slow, and temporary, and connective tissue is too tough.

“Posturology” is the cheesy, popular term for the mostly made-up “discipline” of studying the relationship between posture and pain, and even diseases. Posturologists (I can barely write that with a straight face) tend to assume their own conclusion: they just take it for granted that poor posture does cause pain and then look for confirmation. And so there are many, many scientific papers that seem to present evidence of a connection between posture and pain, but most of them suck (see Guimond et al for a good example) and “posturology” is mostly a slummy pseudoscientific research backwater. There may actually be something to learn, if only posturology research was better quality, but most of it has to be just chucked or at least taken with a huge grain of salt.

However, it probably doesn’t do what you hope it’s doing. Although Epsom salt probably does have some physiological effects, it is unknown if there is a therapeutic effect on aches and pains … and somewhat unlikely. Most of the theories you hear are oversimplified and meaningless — for instance, nearly everyone says it is absorbed by osmosis, but that is false and impossible — and the known effects of Epsom salt don’t have much to do with common causes of pain. The heat of a nice bath is probably more therapeutic. The case for the healing powers of Epsom salt is mostly made by people selling the stuff, or recommending it as casually and imprecisely as an old wives’ tale.

So my blog posts are all in some sense excerpts or rough drafts of larger projects. I very roughly estimate that I actually wrote more than double that much, but only blogged about 175,000 words.

|Popular but Weird and Dangerous Cures+
The colorful history of medicine and quackery is overflowing with people who “swore by” treatments that were bizarre and dangerous. Bloodletting was popular almost until the 20th century, despite being relentlessly harmful. Some of the most lethal “cures” in history were inspired by the discovery of radiation. People happily drank metals like mercury and silver. Even drinking urine had near fad status for a while! They tried to purge disease with sulfuric acid, and stimulate their vitality (and virility) with powerful electric shocks. Women were sold Lysol as a douche … and women actually went along with it for a while. Voluntary lobotomy may be the craziest of them all: it was a popular treatment for all kinds of psychiatric disorders, and at least fifty thousand people volunteered to have their brains lanced.
All of these terrible treatments, and many more obscure examples, had many fans and enthusiastic testimonials. People paid for them, believed in them, loved them, swore by them — that is how misleading testimonials can be. People believe what they want to believe.The most dangerous, strange and yet popular snake oils and “treatments” in history, and why anecdotes and testimonials cannot be trusted

Static stretching vs. “fancy” PNF stretching: which works better? Hold-relax, right?
It’s common for stretching enthusiasts to dismiss my concern that stretching is not all that useful with the concession that, of course, static stretching is quite pointless, but fancier methods (their methods) are “obviously” clinically useful. By far the most common example of allegedly superior stretching is the broad category of “proprioceptive neuromuscular facilitation,” and more specifically the hold relax method. Supposedly this approach works better than mere pulling on muscle. However, this test of the immediate effects HR-PNF versus static stretch on hamstrings was a bust: they both increased flexibility equally well (for whatever that’s worth).

|Does Arnica Cream Work for Pain?+
Homeopathic (diluted) herbal ointments for inflammatory pain, like muscle pain, joint pain, sports injuries and bruising, are quite popular, but their effectiveness is fairly questioned by many. Known to most customers as “herbal” arnica cream, most contain less than 10 micrograms of arnica per dose — dramatically less that what is needed of most substances to be considered a chemically active ingredient. Homeopathy is based on an exotic interpretation of physics that involves diluting ingredients to the point of completely removing them. Some of the herbal ingredients are less diluted and may be chemically active and more useful.
A few tests of homeopathic pain creams have been mildly encouraging, but mostly old and poor quality ones. In all good quality, modern scientific trials so far, they seem to do no better than placebo. It is possible that a benefit can still be proven, but it is not likely.A detailed review of popular homeopathic (diluted) herbal creams like Traumeel, used for muscle pain, joint pain, sports injuries, bruising, and post-surgical inflammation

This sentiment is heard all too often in alternative medicine: “We need some science to prove how treatment modality X works!” No! No no no! That is bass-ackwards. It’s a terrible inspiration for doing science, guaranteed to dial confirmation bias up to 11.
The premise that treatment X “works” is invariably based only on clinical experience, which proves nothing and cannot be trusted. Treatment efficacy must be actually tested and proven rigorously first. We need find out if an idea actually produces measurable medical results and then — if it works, if it actually helps people enough to be measurable — then and only then do we proceed to try to illuminate the mechanism. Stated even more briefly: we cannot study how a treatment works if we haven’t figured out if it works.

Electrosensitivity is an alleged allergy to electromagnetic fields and radiation. It is the basis for paranoia particularly about the health effects of wi-fi networks, power lines, and cell phones — fears that top the charts of human irrationality. There’s little doubt that the afflicted are suffering from something, but it is either an unrelated medical condition or psychosomatic. Electrosensitivity, like (non-celiac) gluten sensitivity, has been thoroughly debunked.
A massage therapist I know described a client who not only refused an electric heating pad, but didn’t even want to to be close to it unplugged. This isn’t a garden variety silly belief — it’s a logical meltdown. If people could actually be so sensitive to electromagnetic fields that they could be hexed by a heating pad’s vibes (let alone an unplugged one), none of them would last a day anywhere in the modern world. It would be an electrosensitive holocaust. They’d vanish in a poof of oversensitive smoke, moths flying into a bonfire.

|Medical Training Wins+
Many alternative health care practitioners, especially chiropractors, claim that they are as well trained as physicians. This is false. Doctor’s academic training is routinely longer, and — more importantly — most of their serious learning occurs during extensive on-the-job training, where they are thrust into demanding clinical environments and supervised for years as they deal with a great variety of clinical situations and many extremely sick and hurt patients. That hands-on phase of their training is where all doctors will tell you that they became professionals — and there is nothing like it in any non-medical health care training.

The idea of “toxins” is usually used as a tactic to scare people into buying de-toxifying snake oil of one sort or another. It’s not that there’s no such thing as a toxin — obviously there are toxic substances in the environment. The problem is the kind of people who toss the idea around, the reasons they do it (profit), and the total lack of any specific claim or scientific knowledge or evidence to support it. It is so vague that it’s literally meaningless, except as a marketing message. Indeed, “detoxification” may be the single most common marketing buzzword in alternative health care, and yet exactly which toxins we’re talking about, or exactly how they are disposed of, is never explained by anyone selling a product that supposedly detoxifies — because they don’t know.
The body deals with undesirable molecules in many ways. It eliminates some and recycles others; some are trapped in a safe place; and quite a few can’t be safely handled at all (metals). Most alleged “detox” treatments are focussed on stimulating an excretion pathway, like sweating in a sauna. But it’s not like sweating is broken and the sauna is fixing it! The only truly “detoxifying” treatments help the body eliminate or disarm molecules the body cannot process on its own. A stomach pump for someone with alcohol poisoning is literally “detoxifying.” So are chelation for heavy metals, and antivenoms.
I cover the specific idea of “flushing” toxins in Should You Drink Water After Massage? (Massage is wonderful for all kinds of reasons — it doesn’t need the support of the idea that it detoxifies.) For more general consumer advocacy and education about toxins, see “Detoxification” Schemes and Scams (from QuackWatch.org).

|Masking Symptoms Is Under-Rated+
“Masking symptoms,” especially with medications, is often maligned because it doesn’t “aid healing” or “treat the root cause.” But masking symptoms can be a perfectly good idea, and it should not be eschewed just because it doesn’t have a real healing effect … because there are very few real healing effects! Maybe none. There are few or no known ways to actually improve on the biological process of healing. We can’t tell the body, “Hey, heal better, will ya?”
“Healing” is mainly about removing impediments to natural recovery, such as continued overuse and excessive stress. It’s not dictated by some mythical power to speed healing, but by a strong understanding of the nature of the problem and what pisses it off and slows recovery. The most idiotically simple example is that bad sprains need to be immobilized for a while, just like a fracture — and maybe that seems “obvious,” but it was actually common practice for decades to recommend excessive early mobilization.
Here’s a classic, trickier example: patellofemoral pain is often misdiagnosed and “treated” with strength training that tends to stress the knee even more, and yet it often works to simply avoid sitting with bent knees, because that position is more biomechanically “intense” than most patients realize. Removing that sneaky knee stress isn’t “healing,” per se, but it’s sure important!
Focus on facilitating natural recovery, and don’t knock a little “symptom relief” along the way.

Confirmation bias explains a lot about human nature. Most people know it best as “selective hearing” or “selective memory” — hearing and remembering only what you want to hear (see also “pareidolia”). Confirmation bias is a whole lot more: a dazzling array of devious and largely unconscious mental tactics and thinking glitches that lead people to confirm their beliefs and pet theories. We not only tend to ignore, deny and overlook anything that contradicts our point of view, but we also invariably notice, inflate and or even fabricate anything that supports it.
Confirmation bias is one of the main reasons that The Truth is so slippery, and both amateurs and experts alike are prone to significant thinking errors. There are people who consider it part of their job description to eliminate confirmation bias from their thinking — the best scientists and journalists, for instance — but it’s really difficult. Everyone has confirmation bias: it’s just how minds (don’t) work!

|What’s a Claim?+
A claim is any unverified assertion. But not all claims are created equal. In health care and health science, “claim” implies a more self-serving assertion. If a claim could be used as a bullet-point in a sales pitch, it’s more claim-y. If it makes you (or your profession) look better, it’s more claim-y. And the more claim-y it is, the more it needs to be backed up.
This special case of the word claim comes from the thorny ethical challenges with selling care to sick, hurt people. All claims need skepticism and verification, but it’s just not as ethically critical if it has no claim-stink. Sagan’s law that “extraordinary claims require extraordinary evidence” is also, in spirit, about more mundane but self-serving and profitable claims — a more common ethical hazard than “extraordinary” claims.

There can certainly be something wrong with your spinal joints — there are a few possibilities — but “subluxation” and spinal joints being “out” are not defined clearly enough to be useful, and are probably quite misleading.
“Subluxation” is mainly a chiropractic idea of spinal joint dysfunction, with many shades of meaning — too many — depending on who is talking about it. However, it is inextricably entangled with the idea of a spinal joint being “out” of place, and it is this sense of the word that needs some debunking. Chiropractors attribute great importance to subluxation. Most believe that subluxations cause neck and back pain, and — significantly — many also believe that they cause a wide variety of other health problems and so they “use spinal manipulation to treat visceral disease” (Homola). Subluxation theory has been both popular and controversial for many decades now, and it has never achieved medical respectability. Many experts, including quite a few chiropractors, actually deny that spinal subluxations exist in any meaningful sense.
It’s problematic that spinal manipulative therapy — the umbrella term for all kinds of spinal joint “adjustment” — is so often based on such a confusing and controversial concept. Subluxation has too much baggage to be a useful term. Let’s use more modern and specific terminology, and get away from the idea of spinal joints being “out.”

|The Simon Singh Story and British Libel Reform+
Simon Lehna Singh’s story is now the most famous example of legal bullying of a science writer for commenting on controversial health care. It has had important consequences for free speech, and great significance to me because I was being legally bullied for similar reasons at the same time.
Simon Singh criticized the British Chiropractic Association for endorsing spinal adjustment for children with conditions like asthma and ear infections, calling it bogus and pointing out the lack of evidence. The BCA sued, exploiting Britain’s nasty libel laws, which bizarrely require defendants to prove themselves innocent at fantastic expense. The case got off to a rough start for free speech with a ruling that Singh could not rely on his only realistic hope, the “fair comment” defence. Nevertheless, Simon appealed and the case became a public relations disaster for the BCA. On April 1, 2010, Simon Singh won his appeal, and the BCA withdrew its lawsuit.
The case catalysed a major on-going campaign to reform British libel law and put an end to the phenomenon of “libel tourism” — corporations suing their critics around the world in Britain, exploiting crazy laws that favour them there. A science writer should be able to comment on genuine concerns on an important public health issue (such as correct treatment for children) without the threat and expense of British High Court libel claims. The cost of an opinion about a controversial health care issue should not be ruinous. In the words of Frank Frizelle: “Let’s hear your evidence, not your legal muscle.”

|Missing Serious Symptoms+
One of the most common and serious basic problems with alternative medicine is that ominous signs and symptoms of serious disease are often overlooked, misinterpreted, and minimized by many overconfident and under-trained “professionals.” Naturopaths, chiropractors, acupuncturists and massage therapists often have a haughty disdain for “mainstream” medicine. I have been constantly exposed to that attitude for many years now — it is much too common.
Of course doctors often also overlook problems — nobody’s perfect (see Medical Errors in Perspective). However, the chances of a doctor missing a scary diagnosis are generally far lower, and particularly so because they have vastly more experience with much sicker people (see Medical Training Wins).

|The Medical Blind Spot for Aches and Pains+
Doctors lack the skills and knowledge to treat most common aches, pains and injury problem, especially stubborn cases, and even the best are poor substitutes for physical therapists. Many doctors are well aware of this, but some are alarmingly oblivious. Dr. Jonathon Tomlinson, an instructor at St. Leonards Hospital in Hoxton, explains that “undergraduate training is focused on hospital orthopedics (broken bones and anything else that’s amenable to surgery) or rheumatology (nasty inflammatory diseases) which comprise a minority of the aches/pains/strains and injuries that people actually suffer from.”
Medical researchers have done many studies showing that most doctors do not understand aches and pains or heed expert recommendations. A good recent example is a paper in the Archives of Internal Medicine showing that family doctors frequently ignore guidelines for the care of low back pain — see Williams et al.
More generally, the Journal of Bone and Joint Surgery, and the Journal of the American Osteopathic Association, have both published papers recently showing that physicians simply do not have an adequate understanding of musculoskeletal medicine. In 2002, Freedman et al felt that “It is ... reasonable to conclude that medical school preparation in musculoskeletal medicine is inadequate.” Then again in 2005 in JBJS, Matzkin et al concluded that “training in musculoskeletal medicine is inadequate in both medical school and non-orthopaedic residency training programs.” Most recently, in 2006, Stockard et al found that 82% of medical graduates “failed to demonstrate basic competency in musculoskeletal medicine.”

|Medical Errors in Perspective+
Alternative medicine practitioners often point accusingly to medical error rates, with the implication that chiropractic, naturopathy and other alternative care is much safer. That’s probably true … in the sense that walking is much safer than driving. But if you routinely had to treat huge numbers of people with life-threatening injuries and dire illness, your profession would have scary error rates, too.
There is no question that bad things happen in hospitals, and stats about iatrogenic (doctor-generated) medical errors can seem alarming. However, to simply state that medicine kills and hurts people is misleading fear-mongering. Cars kill and hurt people too, and for pretty much the same reason: sure it’s risky, but the benefits are worth the risk, and huge numbers of people are willing to take that chance.
Medical systems deal with vastly greater numbers of much more serious cases than any chiropractor or naturopath, and many of them are no-win, rarely-win, or sometimes-lose situations with the highest stakes, terrible suffering and death. We should be cautious about criticizing that from the outside. Try working in a hospital for a while, try to be perfect, try to never have anything go wrong that matters!Medical error rates should not be used to spread fear, uncertainty and doubt

Homeopathy is a 200-year-old medical philosophy that has been thoroughly debunked, and survives today thanks to wishful thinking, ignorance, and because it is too useless to be dangerous. It is the flagship in the alternative medicine fleet: the most popular, profitable, and absurd of all snake oils.
Most people have no idea just how strange homeopathy is. The deal-breaker for many consumers is the discovery that it’s not an “herbal” or “natural” remedy, but a “magical” one, based on a principle that reeks of flaky physics and old-timey snake oil flamboyance—much farther out in left field than herbs. Some people, of course, are quite happy citing quantum physics to explain alternative medicine, but you really have to be a card-carrying new age sort to go there. For most people, that crosses a line.
But they have to find out first! Fortunately, doctors, scientists and skeptics are unanimously and harshly critical of homeopathy, and have published many good quality critical reviews. For instance, see my own article about homeopathic arnica — the most popular of all homeopathic products, intended to treat inflammatory pain.

Healing speed is of great interest, and people often believe that treatment X helped them to heal faster. It’s also a common marketing claim. Unfortunately, most patients aren’t the least bit knowledgeable about what constitutes a normal healing time, and should probably defer to clinicians who have seen hundreds or even thousands of examples — except that they don’t really know either, because they do know that healing time varies wildly depending on countless variables. People often recover faster or slower than expected for reasons no one can ever know. We also seem to recover faster or slower depending on which psychological “goggles” we have on (optimistic, pessimistic, etc).
The bottom line is that the natural variation in healing times tends to obscure the effects of treatments, and simply isn’t actually possible to know if any treatment helped us heal “faster,” because we can never know how long it would have taken without it. You also don’t know what will happen the next time. The only possible way to settle such questions and confirm a faster average recovery time — especially if it’s only a little bit faster — is with carefully designed scientific testing, and quite a bit of it.

|“Reductionism” Is Not an Insult+
Alternative medicine professionals often derisively accuse their critics of being “reductionist.” It is intended to sound wise and knowing, but sneering at “reductionism” is a transparently convenient way to dismiss rational objections to crank theories and flaky bullshit — the main context in which it comes up. It’s a gripe, not a meaningful thought, about those who allegedly can’t see the forest for the trees. It insinuates a lack of vision and savvy about complex systems (like the body). This is quite ironic, coming as it usually does from barely-trained dabblers and dilettantes, people who clearly have not exactly mastered either forest or trees. (Anyone actually capable of being seeing profound patterns in complex systems would be a scientific celebrity.)
Certainly reductionism can go wrong (see Dan Dennett’s concept of “greedy reductionism”). But good reductionism — the real thing, not the insult — is just one of many thinking and reasoning tools … not an all-consuming obliviousness to “the whole.”
