Chiropractic: A Modern Threat to Canadian Health

A Brief History of Chiropractic

No more than a year ago, my preconception of chiropractic was probably similar to that of most Canadians; I assumed that chiropractors were doctors who specialized in back pain as it relates to the spine and musculoskeletal system. As I began to research chiropractic – dissecting both modern practice and historical origins – I found that this simplistic understanding did not account for the wide variety of diagnostic and treatment paradigms that practitioners adhere to. While many chiropractors are experts in the domains of pain and function in relation to the musculoskeletal system and spine, there are many chiropractors who purport treatment of nearly all medical ailments. These chiropractors hold on to age-old beliefs that are steeped in a spiritual mysticism and vitalism.

The invention of chiropractic is attributed to D.D. Palmer. Palmer was originally a magnetic healer who appropriated the osteopathic technique of joint manipulation. He further appropriated the medical term “subluxation” to refer to what he thought were misaligned vertebrae. Positing that these misalignments impinge on nervous tissue which control healing forces within the body, Palmer implicated subluxations as the root cause for all manner of disease. In his book The Science, Art and Philosophy of Chiropractic, he claimed:

D.D. Palmer’s practice of chiropractic may never have gained the following it has today if it weren’t for the mythologizing of a particular extraordinary deed. In 1895 – examining the back of the hearing impaired Harvey Lillard – Palmer claimed to have discovered a bony protrusion. By performing a manual adjustment of the offending vertebrae, Palmer was credited with restoring Lillard’s hearing.

Although the incident is often said to be instrumental to the proliferation of chiropractic, treatment of the deaf is not something found within the scope of modern chiropractic. In fact, no chiropractor has performed the procedure successfully under controlled conditions. The challenge of repeating this chiropractic miracle is likely attributable to the anatomy of hearing (something we now more clearly understand); the auditory nerves reside exclusively within the skull and at no point travel down the spine. To put it bluntly: chiropractic cannot heal the deaf.

As chiropractic first expanded, some practitioners incorporated radical religious and philosophical beliefs. The adoption of religious symbolism and ideology was – in part – a ploy by Palmer to protect chiropractors from prosecution for practicing medicine without a license. Although much of Palmer’s writings were contradictory and far from concise, his philosophy generally describes a Universal Intelligence (God) that manifests as an Innate healing power channeled through the nervous system and spine.

In essence, Palmer’s principles of chiropractic assert that subluxations result in interference between the Innate vitalistic force and the body by compressing the nerves, causing disease. When chiropractors perform adjustments on patients, they claim to be completing the body’s connection with Innate, allowing it to perform its healing ability. It is this practice that led chiropractors to coin the notion of, “connecting man the physical with man the spiritual,” which is often expressed as turning people’s power on.

Of course, no one would believe these things in this modern age would they? Actually, London’s own celebrity chiropractor B.J. Hardick evidently subscribes to a very similar worldview:

While many current practices today developed from mythologies of the past, chiropractic is unique for retaining much of its philosophical and religious heritage. It’s not uncommon today to hear chiropractors reference Innate or subluxations within their practice. Although the term subluxation does have an appropriate medical use, chiropractors have manipulated it to fit their own design. The lack of substantiation for vertebral subluxation did little to impede the proliferation of chiropractic.

If subluxations are a valid source of concern, we should be able to identify them, illustrate their causal link to disease, and demonstrate that their treatment has a positive effect on specific disease processes and patient symptoms. In 2009, a group of chiropractic researchers examined the evidence relating to subluxations and found “no supportive evidence . . . for the chiropractic subluxation being associated with any disease process or of creating suboptimal health conditions.” Some chiropractors took issue with the findings, but none put forward a substantive critique. Indeed, when suggesting a novel scientific paradigm, the burden of proof rests on those who make extraordinary claims.

While practitioners of unproven techniques often recall the aphorism that an absence of evidence is not evidence of absence, after years of investigation, evidence of absence is precisely what plagues the chiropractic subluxation. The British General Chiropractic Council denounced the subluxation complex in 2010, followed by additional chiropractic institutions in 2015. Despite the fact that there is no evidence or plausible biological mechanism to validate subluxations as the cause of disease, and despite the fact that chiropractors can’t reliably identify subluxations, some chiropractors continue to apply this philosophy in their clinical treatment. Prominent chiropractors in support of evidence-based practice have noted the detriment to public health that is subluxation theory.

In his book Chiropractic Abuse: An Insider’s Lament, chiropractor Preston Long details how the chiropractic profession is plagued by unscientific beliefs that have persisted in spite of their clash with modern scientific and medical knowledge:

“I am a chiropractor. I do not say this with pride. My profession is full of men and women who exaggerate what they can do and provide unnecessary and sometimes dangerous services to their patients. Most chiropractors are not bad people, but far too many embrace cult-like beliefs.”

Chiropractic Abuse by Preston Long

Reformation

Today, a contentious rift exists within the chiropractic community. There even exists terminology to demarcate between those clinging to the ideas of the past and those who incorporate novel techniques: straights (often self-described as principled) are those who follow the classical Palmer doctrine whereas mixers are those who incorporate other techniques including modern scientific understanding of disease processes (although mixers sometimes pursue equally suspect health practices). This leaves us with two different chiropractic philosophies. The former (the straights) generally believe that subluxations are the root cause of most disease and that a lifetime of spinal adjustments is essential for maintaining proper health. The latter (the mixers) apply spinal manipulation therapy to relieve musculoskeletal pain and generally work with patients to improve mobility and function.

So if the subluxation is a mythical concept, what benefits do chiropractors offer? A 2011 Cochrane review examined the use of combined chiropractic interventions for what chiropractors are most known for: treatment of lower back pain. While they found evidence that “chiropractic interventions slightly improved pain and disability in the short term and pain in the medium term for acute/subacute” lower back pain, they concluded that “there is currently no evidence that supports or refutes that these interventions provide a clinically meaningful difference for pain or disability in people with [lower-back pain] when compared to other interventions.” Follow up research examining spinal manipulation therapy reached a similar conclusion in 2013.

In addition to lower back pain, there is some evidence indicating that spinal manipulation may aid migraines, as well as neck pain. While the evidence is weak, this may be a result of biomechanical variability among patients, causing some patients to respond well to treatment but not others. After all, many patients swear by chiropractic; while recent Gallup polls illustrated that the American public finds physical therapy generally more effective and safer than chiropractic for neck and back pain, chiropractic care did rank higher than all other interventions. Indeed, many patients are satisfied with their chiropractic care. Despite the mixed evidence, there may be a future for spinal manipulation therapy in treating some pain and disability. If chiropractors can help curtail the opioid crisis as they purport, then their deployment in conservative musculoskeletal care is welcomed.

Unfortunately, a significant impediment to healthcare integration is the division within the chiropractic community. Chiropractic’s historical baggage has led to disparate professional identities, causing criticism from the medical community, particularly among orthopedic surgeons. It’s not hard to see why. Many chiropractors make outlandish and unsubstantiated claims regarding treatment of conditions unrelated to the musculoskeletal system. While evidence-based practitioners generally offer manipulations with the intent of mobilizing joints, those in the straight community claim to precisely adjust misaligned vertebrae and restore them to their proper positions. These claims are dismissed even by chiropractic researchers, yet many practitioners still offer these unscientific services.

A Legacy of Anti-Science

Subluxation-based chiropractic is a treatment in search of a disease. Unlike most medical research which seeks to evaluate novel treatments and diagnostic techniques, chiropractic research is still trying to vindicate an age-old approach to health. This led the American Medical Association to label chiropractic an “Unscientific Cult” as early as 1969. In response, chiropractors sued. Though the AMA lost in an antitrust suit (not by scientific merit), the war continues to this day and chiropractors have still not demonstrated the existence of the subluxation.

In contrast to health practices like physiotherapy or massage, subluxation-based chiropractors are particularly vocal in their opposition to the medical system. A likely explanation – aside from the obvious history – is that physiotherapy, massage, and even modern chiropractic are exclusively complementary to medical practices. Quite distinctly, subluxation-oriented chiropractors often find themselves in competition with the medical system; after all, subluxation-based chiropractors consider their treatment to remedy the cause of most afflictions (despite the lack of evidence). A simple Google search involving the term ‘chiropractic’ and any disease will produce unsavory results. Even chiropractic’s patriarch D.D. Palmer spent time in jail for practicing medicine without a license.

Perhaps the most repugnant philosophical stance that remains pervasive in the chiropractic world is the fervent opposition to vaccination. While scientists and public health experts unanimously recognize vaccination as an effective approach to prevent disease with little risk, the topic remains a contentious issue within the world of chiropractic. D.D. Palmer’s son, B.J. Palmer – the great promoter of chiropractic – is largely responsible.

“The idea of poisoning healthy people with vaccine virus . . . is irrational. People make a great ado if exposed to a contagious disease, but they submit to being inoculated with rotten pus, which, if it takes, is warranted to give them a disease.”

With a long history of opposition to vaccination, chiropractors who cling to the ideas of the past put children at risk and endanger public health. If you think that chiropractic in Canada has outgrown its superstitious and unscientific views, you would be wrong. A recent investigation uncovered significant promotion of anti-vaccination propaganda among Manitoba chiropractors, leading to calls for proactive oversight and regulation. Some chiropractors are even ignorant enough to make media statements against vaccination.

“My parents chose to opt me out of the routine vaccination schedule many years before the world was paying attention to mercury toxicity, Autism, studies, or anything else … My parents wanted me to develop my immune system naturally, without interference.”

Anti-vaccination beliefs aren’t the only risk posed to children by chiropractors. One area in particular where chiropractic has received extensive criticism from the medical community is in the domain of pediatrics. Many chiropractors in Ontario and abroad have made outlandish claims with regards to chiropractic treatment for infants and children. While there are documented consequences from chiropractors working on infants, precise rates of complication are unknown – likely a consequence of poor adverse event documentation and reporting.

“There’s nothing that I love more than seeing a kid jumping up on the table . . . make sure they’re subluxation free and whether it ever elicits a symptomatic change in that child or not, just being able to know that we’ve turned on the power.”

B.J. Hardick is a prominent example of a chiropractor promoting treatments for infants and children. The following images were all scraped from his professional Facebook page:

The absurdity of chiropractors treating infants is only eclipsed by what they claim they are treating; many chiropractors advocate for treatment of children with ear infections, asthma, colic, and other non-musculoskeletal conditions. It’s important to note that the vast majority of conditions that chiropractors treat in children are self-limiting – they tend to resolve spontaneously. A prominent example is colic, for which there is no evidence supporting chiropractic treatment.

Dr. Harriet Hall Chiro
Retrieved Jan. 2017 from here.

In Canada, the problem is pervasive enough that the Canadian Pediatric Society released a position paper: “Chiropractic care for children: Controversies and issues. The original position was posted in 2002 and reaffirmed in 2016. When examining the scientific evidence, they found that there was no evidence for chiropractic to treat any pediatric disorder. Instead, they found that chiropractors put children at risk by spreading misinformation regarding immunization and by attempting to treat acute pediatric conditions that instead need serious medical treatment. These weren’t the only risks identified. The authors noted that “parents should be made aware that there is a lack of substantiated evidence for the theory of subluxated vertebrae as the causality for illness in children, and x-rays taken for this purpose expose the child to unnecessary radiation.” In fact, chiropractors often overuse x-rays. Even for lower back pain, Choosing Wisely Canada recommends against x-rays partly because it has not been shown to improve management of symptoms. Naturally, misuse of X-ray technology has a long history in chiropractic. B.J. Hardick himself claims that it’s dangerous to adjust without x-rays and has showcased x-rays of children in his YouTube videos.

In a further affront (conscious or otherwise) to public health, many chiropractors attribute risk of subluxation to how the baby is delivered (here is a prime example). Not only are they doing a disservice to public health, but they are unnecessarily shaming mothers about their personal choices regarding the birth process.

“The more natural the delivery, the less interference, the fewer interventions medically that are necessary, the less trauma to the skull . . . I had a baby last week where unfortunately based on the way the baby was presented, they had to turn the baby manually inside the mom and then pull the baby out. So the baby’s neck was definitely subluxated.”

“One fact we do know, however, is that the first subluxation usually happens in the birth canal because of the normal trauma associated with vaginal deliveries. Even babies delivered by C-section are subject to birth trauma and vertebral subluxation. This is why it is absolutely critical for parents to bring their babies to their chiropractor as soon after birth as possible. This will ensure that their child’s nervous system is functioning at full capacity, which will provide the framework for a long life of health and vitality.”

Where are the regulators?

In 1991, chiropractors became authorized to use the title ‘doctor’ under the Chiropractic Act. This privilege has been used irresponsibly by chiropractors nation-wide when making public statements on medical concerns unrelated to musculoskeletal issues. When the public is likely to conflate the use of the title ‘doctor’ with ‘medical doctor’, it is irresponsible to apply the title in the context of non-musculoskeletal medical advice; this is especially true when practitioners are disseminating misleading information.

The College of Chiropractors of Ontario is the self-regulating body for chiropractic in Ontario. As authorized in the Chiropractic Act, the chiropractic scope of practice is as follows:

  • The practice of chiropractic is the assessment of conditions related to the spine, nervous system and joints and the diagnosis, prevention and treatment, primarily by adjustment, of,
    • (a) dysfunctions or disorders arising from the structures or functions of the spine and the effects of those dysfunctions or disorders on the nervous system; and
    •  (b) dysfunctions or disorders arising from the structures or functions of the joints.

The problem is that the application and enforcement of this scope is open to broad interpretation. If you subscribe to the classical subluxation philosophy and believe that spinal adjustments channel the healing power of Innate through the body, what could possibly be considered outside of a chiropractor’s scope of practice?

How pervasive is the belief among practitioners that chiropractic can effectively treat a wide range of medical conditions unrelated to the spine? Unfortunately, it is not known. No regulatory body surveys and disseminates this information and existing literature on the topic is unreliable at best. A recent survey of Canadian chiropractors indicated that large proportions of chiropractors in clinical practice use entirely unsubstantiated diagnostic and treatment techniques (for example, 22% claimed to prescribe homeopathy – a treatment that isn’t only unproven but implausible).

Ultimately, the regulatory body has not enforced evidence-based practices, resulting in a vast number of chiropractors who sell useless, even dangerous treatments. My article regarding the Byron-based chiropractor who uses a cheap ear thermometer to diagnose subluxations is a prime example of a chiropractor running a successful business in spite of either having no idea what he is doing, or consciously conning his patients. It’s worth repeating: where are the regulators?

Unfortunately, patients seeking responsible chiropractic care must be extra diligent in screening their care provider. My advice would be to take time to examine the chiropractor’s website. Do they make absurd claims regarding non-MSK conditions? Do they treat infants? Do they treat subluxations? Do they offer long-term treatment/payment plans? Do they advertise testimonials regarding conditions outside of the scope of chiropractic? Do they perform x-rays on every patient? If the answer is yes to any of these, you’re very likely dealing with a quack.

“Good chiropractors are essentially physical therapists who specialize in the spine. Spinal manipulation is an effective option for mechanical low back pain, but physical therapists and some doctors also use that treatment. Some chiropractors want to be primary care providers and treat a variety of non-MSK diseases, but they are not trained to do that. Many chiropractors subscribe to outright quackery like applied kinesiology; and only half of them support vaccination. A medical subluxation is a partial dislocation of a joint that is readily visible on x-ray; the “chiropractic subluxation” is a myth and does not show on x-ray. And chiropractic can be dangerous: stroke is a rare but devastating complication of neck manipulations.”

The Oil Rush: How Health Canada has Failed to Regulate Deceptive Health Products

My former roommate was an early adopter of essential oils. Using a diffuser (ultrasonic humidifier) to spread fragrances house-wide, I would come home to aromas of peppermint, orange, and lavender instead of the familiar musty scent baked into our basement apartment. Sold on the efficacy of essential oils in reinvigorating stagnant air, I too became a user. In a rational world, this is where the story would end. Unfortunately, we do not live in a rational world.

Essential oils have taken upper middle class suburbia (and by extension Instagram) by storm. Social media platforms – once the refuge of dank memes and animal pictures – are now home to the blurred line between people’s personal lives and their multi-level marketing schemes. What’s particularly frightening, however, is how quickly each exciting new business opportunity has become the path to true health and wellness.

If you believe everything you read, you might think that essential oils are here to cure cancer, solve world hunger, reverse climate change, and ultimately prevent the impending heat death of the universe. You might think that essential oils have been divinely bestowed on us to empower stay-at-home parents to become entrepreneurs and health gurus while simultaneously enriching themselves, their communities, and the world around them. You would be wrong, but I can’t blame you.

Essential oils have been marketed relentlessly and deceptively by multi-level marketing organizations that profit from our modern addiction to wellness. Although Young Living pioneered the business of deceptive essential oil marketing, doTERRA made it a household affliction through their consultants’ insistence that oils could treat anything from asthma to Ebola.

In reality, essential oils have not been demonstrated to be particularly effective at preventing or treating any disease or condition. It wasn’t long before both the EPA and the FDA took action against this blatant pseudoscience, prompting doTERRA to go on the defensive. Now, rather than instructing their consultants to make unsubstantiated health claims that are illegal, doTERRA provides guidelines for consultants that employ semantics to avoid those pesky science-based regulators:

Of course, there isn’t even good evidence that essential oils satisfy any of the “Structure-Function Claims,” but the mildness of the claims are enough to appease the FDA. As unfortunate as it is for public health, however, doTERRA advocates are not mild people.

In London, we are home to Canada’s first Presidential Diamond doTERRA representative: Ange Peters. In their not-at-all-a-pyramid-scheme compensation plan, the honor of Presidential Diamond is bestowed only on those who have climbed to the top and profited from those below.

Although Peters claims to guide women to true HEALTH, her social media is not filled with responsible health advice.

But I digress; what troubles me more than the content of my social media feed is the content of Peters’ advertising. The sheer magnitude of misleading medical claims that appear on Peters’ various platforms is staggering. Her own “Getting Started with Oils” guide provides a compendium of medical recommendations for essential oil, which can be accessed by clicking the prominently displayed “Health Concerns” graphic:

In this encyclopedia of serious medical conditions, various criticisms are levied against effective medical treatments. Instead, specific essential oil “Protocols” are offered for every affliction you can think of. Of course, none of them are proven to work in any capacity, hence the inclusion of the Quack Miranda Warning. In many cases, these “treatments” likely do more harm than good.

Although the domain of this site is registered to doTERRA, the content was taken offline some time ago, presumably in response to the crackdown by the FDA.

The vitamin and mineral comment likely stems from a landmark 2004 study (and similar studies) that saw a small reduction in some nutrients among cultivated crops, likely attributable to changes in soil composition and changes in cultivated varieties. It’s a worrying trend and certainly something to keep an eye on, but to say we need to eat five times the food today for the same vitamin and mineral intake is nothing short of ignorant. The claim grossly overstates the reduction and doesn’t identify which foods or even which nutrients in those foods are impacted. Further, do these changes even impact our health in any capacity? I get the impression that Peters hasn’t read the primary scientific literature.

Peters often claims to be “passionate about educating and empowering women to live their best life through natural solutions”. In reality, Peters is empowering her audience to take big risks with their health and their finances. Unfortunately, doTERRA has laid the foundation for Peters and other like-minded practitioners to prosper unabated while organizations like Health Canada have been complicit and ineffective in preventing false health claims. Whether a result of incompetence or ignorance, Health Canada – the organization mandated to protect the public from dangerous and ineffective health products – has failed.

In what is certainly an effort to find a balance between consumer demand and public health, Health Canada allows for the registration of Natural Health Products – products which are supposed to be screened to ensure they are “safe, effective and of high quality.” The problem, however, is that a vast number of registered products have literally no scientific evidence supporting the claims they are permitted to make. So how did they come to be registered?

In place of scientific evidence, Health Canada will accept “Tradition Use Claims. So if someone once used an ingredient, made up a claim about it, and then wrote it in a pharmacopoeia, products using this ingredient can register as natural health products and make the same claims – true or not. This is an ongoing failure of Health Canada that the CBC frequently illuminates. It’s the same flaw doTERRA has exploited.

Let’s look at a specific example: doTERRA’s Juniper Berry Essential Oil. On their Approved Claims List, doTERRA permits Canadian representatives to make a number of aromatherapeutic claims:

doTERRA - Juniper Berry
Retreived Dec. 2017 from: http://media.doterra.com/ca-otg/en/flyers/approved-claims-list-ca.pdf

Here’s the problem: Health Canada’s monograph for juniper essential oil doesn’t contain a single scientific or clinical study supporting its use for anything. Nonetheless, the oil is a registered natural health product, citing juniperus communis as a medicinal ingredient – a compound that also lacks scientific evidence from Health Canada for oral use.

A lack of regulatory controls on health products can have serious consequences. Not everyone is privileged enough with time and resources to conduct a thorough review of health claims. When essential oil companies boast that their products are registered natural health products, it lends legitimacy to the outlandish claims, emboldening proponents to believe that they were right all along about every mystical claim attributed to what is simply an aroma. As a result, listening to doTERRA advocates is like listening to a child talking about all the things Santa’s elves can do. Health Canada needs to be the one to tell her that Santa isn’t real.

I should be clear that I don’t believe Ange Peters acts maliciously. Although I wouldn’t say her business is innocent of profiteering, I get the sense that she feels her beliefs are vindicated. After all, she has amassed an audience of happy and healthy followers. Every successful customer is not just a business win, but a philosophical win. These are the people who I worry about the most.

When one of her clients asks “Does terrazyme help fight against disease?” and Peters answers Yes,” it condemns her audience to spend time and money chasing supplements that have no clinical evidence for preventing disease. Some may seek these products in place of legitimate medical care, but as it stands, doTERRA is not a medical company and essential oils are not medicine.

Despite not living up to their hype, I don’t hold anything against essential oils. In fact, I still use them nightly in my diffuser. Why? They smell nice and I enjoy it. What I won’t do is purchase from unethical companies like Young Living and doTERRA that have profited from misleading health claims and a predatory business model.

The Chiropractor’s Toy

I’ve been keeping my ear close to the ground on all things chiropractic lately, often coming across strange and unethical practices that are in need of a well-deserved scientific flogging. Most of these I let pass in anticipation of a bigger catch, but there is one practice that I can’t get over how funny it would be if it weren’t so troubling. First, some history.

Chiropractic originated from the father and son team of D.D. Palmer and his younger counterpart B.J. Palmer. Papa Palmer is largely attributed as the inventor of chiropractic, but B.J. Palmer and his unparalleled marketing skills helped make the profession what it is today. A prolific promoter, B.J. was an author, a radio host, and even at one point a circus hand. He was certainly no stranger to gimmicks.

In expanding the diagnostic scope of chiropractic practice, B.J. introduced two devices into the clinic. The first was the x-ray machine, which is often of no use when treating lower back pain and is recommended against by Choosing Wisely Canada. Despite this, they are used widely by chiropractors in the treatment of lower back pain. The second device, was the neurocalometer – a gadget that B.J. fervently advertised and sold. What’s unique about the neurocalometer is that even many chiropractors agree that its introduction and promotion was unethical.

The Neurocalometer
The Neurocalometer [source]
So what is the neurocalometer? It’s a thermometer. No really, it’s basically just a thermometer.

The idea is that chiropractors use temperature as a gauge to measure subluxations – displacements of the vertebrae that impinge on the spinal nerves. They (I should be clear – not all chiropractors) believe that this interference in the nerves causes dissipation of heat to surrounding tissue, allowing them to precisely diagnose subluxations. There’s just one problem: subluxations don’t exist. In fact, a group of chiropractors and researchers found no evidence that they exist or are causally related to any disease process. Despite this, a large number of chiropractors still claim to be able to diagnose and treat the mythical vertebral subluxation.

As you can imagine, since vertebral subluxations don’t exist, there isn’t much hope for the neurocalometer as an effective diagnostic instrument, but it gets worse; even the Canadian Chiropractors Association stated that the “validity and reliability of measurement are highly doubtful.” This makes sense. Even if we granted the existence of subluxations, do nerves create heat when pinched? If nerves create heat when pinched, is it enough to be measured? Is enough heat created to be measured indirectly at the surface of the skin? The answer to all of these questions is an affirmative no.

Regardless, many chiropractors still make use of variants of the neurocalometer at great expense to their credibility. Luckily, crafty chiropractors at least avoid the great expense to their overhead and recognize that neurocalometers are really just overpriced thermometers. So why not just use a cheap ear thermometer instead? They measure surface temperature and are much more widely available. Even though they might not be very reliable, they make up for it by being cheap and easy to come by. You can even pick them up at Toys R Us:

In fact, one local chiropractor uses a similar (if not the exact same) model in a video “demonstrating” its use:

Source: “London, Ontario Newborn Adjustment” Retrieved from: London, Ontario Newborn Adjustment

That’s not to say the thermometer doesn’t work; it certainly is a real thermometer, but what is the chiropractor using it for? Well, in the video posted by his practice to Facebook (which my good friend Dennis forwarded to me), he is using it to diagnose subluxations. On a 2-week-old infant.

I left a comment on the post expressing my concerns. It was promptly removed and I was blocked from the page. After composing the initial draft of this article, I sent it to the Kay Harris Chiropractic & Wellness Center asking if they would respond or at least offer corrections if they found issues. They haven’t responded. Why is it that chiropractors have the audacity to promote such things without the integrity to defend them?

Remember, subluxations are to chiropractors as the tooth fairy is to children; they don’t exist, but still seem to bring in the money. That’s not all; there is no reason to think that chiropractic offers any benefits to children:

I don’t know of any reason to believe that it might be necessary to refer a child to a pediatric chiropractor or to use spinal manipulation on a child prior to onset of adolescence. “Wellness care” in the form of “subluxation correction” is unnecessary and scientifically indefensible, and it places children at risk. 

 -Sam Homola, Chiropractor

Yet here is a chiropractor with an infant in one hand and a thermometer in the other. He claims that treatment for a subluxation is needed for a 0.2 degree differential in temperature. Well not only are ear thermometers not designed for this purpose, but they are not terribly accurate. The thermometer in question has an accuracy of ±0.2°C even though its display resolution is 0.1 °C. It might be surprising to you at this point, but that means that a 0.2 degree differential cannot be reliably measured with this device. Because the accuracy is even worse outside its normal operating range, it’s likely that the device couldn’t even diagnose Harvey Lillard‘s Mother of all Subluxations. That is, if subluxations existed.

Further, according to the manual, “this thermometer is intended for household use only.” So I hope the chiropractor’s practice is at home; I want him to be comfortable when he hears this: what you are doing in this video is entirely useless.

Stay Scientific.
