Biopuncture is a therapy whereby specific locations are injected with biological products. The majority of the products are derived from plants. Most of these injections are given into the skin or into muscles. Products commonly used in Biopuncture are, for example, arnica, echinacea, nux vomica and chamomile. Arnica is used for muscle pain, nux vomica is injected for digestive problems, echinacea is used to increase the natural defense system of the body. Biopuncturists always inject cocktails of natural products. Lymphomyosot is used for lymphatic drainage, Traumeel for inflammations and sports injuries, Spascupreel for muscular cramps. Injections with antiflogistics, hyaluronic acid, blood platelets, blood, procaine, ozon, cortisone or vitamin B are not considered as Biopuncture…
How can such a small dose influence your body and stimulate healing? Scientists don’t have the final proof yet, but they postulate that these injections are working through the stimulation of the immune system (which is in fact your defense system). Let’s compare it with a vaccination. When you receive a tetanus vaccination, only small amounts of a particular product are necessary to stimulate the immune system against lockjaw. In other words, just a few injections can protect your body for years…
An important issue in Biopuncture is the detoxification of the body. It literally means “cleaning the body” from all the toxins that have accumulated: for example from the environment (air pollution, smoking), from bad nutrition, or from medication (e.g., antibiotics and steroids you’ve taken). These toxins can block your defense system. Some injections work specifically on the liver and others on the kidneys. Cleaning up the lymphatic system with Lymphomyosot is considered very important in Biopuncture. It is like taking the leaves out of the gutter. The down side of such an approach is that old symptoms (which have been suppressed earlier on) may come to the surface again. But that is sometimes part of the healing strategy of the body…
That sounds strange, to say the least. But remember: strange treatments might still work! The question is therefore: IS BIOPUNCTURE AN EFFECTIVE THERAPY? If you ask it to Dr Oz, the answer would be a resounding YES – but let’s not ask Oz, let’s try to find some reliable evidence instead. In my quest to locate such evidence, I came across claims like these.
Examples of some acute conditions we treat with biopuncture:
- Knee and ankle sprains
- Muscle sprains- quadriceps, hamstring, adductors, rotator cuff
Examples of some chronic conditions we treat with biopuncture:
- Achilles tendinitis
- Tennis elbow
- Chronic arthritis of the knee, hip, shoulder
- Back pain
- Myofascial pains
- Irritable bowel syndrome
- TMJ syndrome
Somehow I had the feeling that this was more than a little too optimistic, and I decided to conduct a rudimentary Medline search. The results were sobering indeed: not a single clinical trial seems to be available that supports any of the claims that are being made for biopuncture.
So, what should we conclude? I don’t know about you, but to me it seems that biopuncture is quackery at its purest.
The question that I hear with unfailing regularity when talking about alternative medicine is WHY IS IT SO POPULAR? I always struggle to find a simple answer – mainly because there is no simple answer. The reasons for patients and consumers to use alternative medicine are complex and multiple. They range from dissatisfaction with conventional medicine to clinging to the last straw. However, one factor is very clearly always involved: the often bafflingly uncritical promotion of quackery by the daily papers – and that even includes those with a reputation for being respectable.
Yesterday’s article in THE TELEGRAPH is as good an example as any. In the following section, I quote excerpts from it and add my own comments in bold.
It is perhaps easier to list what the naturopath Katrin Hempel doesn’t offer her clients than what she does. “Bioresonance and live blood analysis, acupuncture, biopuncture, infusion therapy, oxyvenation…”
Katrin Hempel, B.H.Sc.,ND, Dipl.Ac. describes herself on her website as an energetic, enthusiastic and experienced natural therapist with a great passion and commitment to the health and well-being of her patients. She calls herself a ‘naturopathic doctor’. I am not sure what this actually is but I am fairly sure she has not studied medicine. I do not doubt her enthusiasm, but I do doubt that most of the methods listed above are anything else but pure quackery.
“Germany has a long tradition of natural medicine, so it’s more common to find conventional doctors who have also studied natural medicine and use these modalities. Here we are at least 20 years behind.” That is true only, if one regards the integration of quackery as progress.
“Every cell in the body puts out a certain electromagnetic frequency, that can be measured – a healthy stomach cell sounds different to a healthy brain cell – and the machine can put the right resonance back in, to trigger deep healing.”) This is pure pseudoscience; neither live blood analysis nor bioresonance are supported by good evidence (and don’t even ask about ‘biopuncture’).
The article goes on misleading the reader in the most scandalous way by promoting pure nonsense. To provide a flavour, I will merely cite a few quotes from the ‘naturopathic doctor':
- “If your digestion isn’t working properly there is a malabsorption of nutrients”
- “Bioresonance can pick up a condition before it manifests as a disease.”
- “Bioresonance measures the electromagnetic output of every cell in the body. If there’s any discrepancy with the healthy frequency for that kind of cell that gives a diagnosis.”
- “Whatever the problem, at root it will be an imbalance in the cells.”
At no point in this article is there an attempt to challenge or critically analyse this bonanza in quackery; THE TELEGRAPH promotion of dangerous nonsense ends with the cheerful footnote informing the reader that one hour with the ‘naturopathic doctor’ will cost from £100. THE TELEGRAPH does not even shy away to print an address for booking a consultation with the ‘naturopathic doctor’.
But is it really all quackery? Yes it is! The article promotes so many unproven methods that I find it hard to choose one for demonstrating how irresponsible it really is. Let’s take life blood analysis (LBA), for instance; here is what I published about LBA some time ago:
The principle of LBA is fairly simple: a drop of blood is taken from your fingertip, put on a glass plate and viewed via a microscope on a video screen. Despite the claims made for it, LBA is by no means new; using his lately developed microscope, Antony van Leeuwenhoek observed in 1686 that living blood cells changed shape during circulation. Ever since, doctors, scientists and others have studied blood samples in this and other ways.
What is new, however, is what today’s “holistic practitioners” claim to be able to do with LBA. Proponents believe that the method provides information “about the state of the immune system, possible vitamin deficiencies, amount of toxicity, pH and mineral imbalance, areas of concern and weaknesses, fungus and yeast”, as another website puts it.
Others dare to be much more concrete and claim that they can “spot cancer and other degenerative immune system diseases up to two years before they would otherwise be detectable”; or say they can diagnose “lack of oxygen in the blood, low trace minerals, lack of exercise, too much alcohol or yeast, weak kidneys, bladder or spleen”. All this would amount to a remarkable discovery if it were true. But it’s not.
No credible scientific studies have demonstrated the reliability of LBA for detecting any of the above conditions. In what was, to the best of my knowledge, the first attempt to assess the value of this method, a practitioner with several years of experience in LBA tested the samples of 110 patients. Twelve had cancer and the task was to identify their samples without knowing further details. The results could hardly have been more disconcerting – just three of the 12 with confirmed cancer were detected, and the authors concluded that the method “does not seem to reliably detect cancer. Clinical use of the method can therefore not be recommended.”
And, in case you do not trust me, here is a recent Advertising Standards Authority ruling on LBA:
London Natural Therapies is in breach of the UK Advertising Standards Code for making unproven claims on its website about Live Blood Analysis. The CAP Compliance team has contacted London Natural Therapies several times about removing claims implying that Live Blood Analysis could be beneficial for Gastro Intestinal Tract Disorders, Allergies and Hormonal Imbalances after the ASA previously ruled that Live Blood Analysis was not effective in detecting/diagnosing those conditions. Despite repeated requests to remove the problem claims, London Natural Therapies continues to feature them on its website, www.londonnaturaltherapies.co.uk. Because of London Natural Therapies continued non-compliance we took the decision to place its details on this section of the ASA website on 26 June 2012. These details shall remain in place until such time as London Natural Therapies has removed or appropriately amended the claims on its website to ensure compliance with the CAP Code.
This is but one of many examples of truly shoddy journalism published in a daily paper that most people would call ‘respectable’. If anyone cares to look at the less respectable end to the journalistic spectrum, the picture gets even more horrific. The points I am trying to make are simple and, I think, important:
- Journalists and editors have a responsibility which, in the realm of alternative medicine, they often disregard most scandalously.
- Such poorly researched, unbalanced and uncritical articles can cause very serious harm.
- The promotion of quackery may be good for selling copy, but it can also quickly ruin the reputation of a paper.
If you have diabetes, chances are that you need life-long treatment. Before effective anti-diabetic medications became available, diabetes amounted to a death sentence. Fortunately, these times are long gone.
…unless, of course, you decide to listen to the promises of alternative practitioners many of whom offer a cure for diabetes. Here is just one website of hundreds that does just that. The following is an abbreviated quote where I have changed nothing, not even the numerous spelling mistakes:
Modern medicine has no permanent cure for diabetes but alternative medicines like yoga ,mudra,ayurveda is very useful to control and even cure diabetes.Ayurveda is an alternative medicine to cure diabetes.
Alternative medicine like ayurveda is a best to cure diabetes naturally.
A serious disorder of the glands,of pancreas to be exact,is diabetes,or madhumeha as described in ayurveda.It is one of the most insidious disorders of the metabolism and,if left undiagnosed or untreated,it may lead to rapid emaciation and ultimately death…
Ayurveda medicines to cure diabetes
In ayurveda the following medicines have been recommended for this disease
Shiljita ————————–240 mg
Nyagrodadhi churna ———3 gm
These should be given twice after meals with decoction of arni.
Vasantakusumakara rasa —120 mg
Shudha Shilajit ————–240 mg
Nag Bhasma —————–120 mg
Haldi ————————–500 mg
Amlaki Churna ————-500 mg
Twice daily with powder of rose-apple stones.Twice daily with honey.
Chadraprabha Vati ——– 500 mg
Mudra the alternative treatment to cure diabetes naturally
Mudra is a non medical and no cost treatment to cure diabetes.You can perform mudras at any time or any position.It is an effective way of treatment you can get better result if you practice it regularly .
It goes without saying that none of these treatments would cure diabetes. A Cochrane review concluded that there is insufficient evidence at present to recommend the use of these interventions in routine clinical practice. It also goes without saying that not many patients would fall for the nonsense proclaimed on this or so many other websites. But even just one single patient dying because of some charlatan promising a cure for life-threatening diseases is one patient too many.
Acute tonsillitis (AT) is an upper respiratory tract infection which is prevalent, particularly in children. The cause is usually a viral or, less commonly, a bacterial infection. Treatment is symptomatic and usually consists of ample fluid intake and pain-killers; antibiotics are rarely indicated, even if the infection is bacterial by nature. The condition is self-limiting and symptoms subside normally after one week.
Homeopaths believe that their remedies are effective for AT – but is there any evidence? A recent trial seems to suggest there is.
It aimed, according to its authors, to determine the efficacy of a homeopathic complex on the symptoms of acute viral tonsillitis in African children in South Africa.
The double-blind, placebo-controlled RCT was a 6-day “pilot study” and included 30 children aged 6 to 12 years, with acute viral tonsillitis. Participants took two tablets 4 times per day. The treatment group received lactose tablets medicated with the homeopathic complex (Atropa belladonna D4, Calcarea phosphoricum D4, Hepar sulphuris D4, Kalium bichromat D4, Kalium muriaticum D4, Mercurius protoiodid D10, and Mercurius biniodid D10). The placebo consisted of the unmedicated vehicle only. The Wong-Baker FACES Pain Rating Scale was used for measuring pain intensity, and a Symptom Grading Scale assessed changes in tonsillitis signs and symptoms.
The results showed that the treatment group had a statistically significant improvement in the following symptoms compared with the placebo group: pain associated with tonsillitis, pain on swallowing, erythema and inflammation of the pharynx, and tonsil size.
The authors drew the following conclusions: the homeopathic complex used in this study exhibited significant anti-inflammatory and pain-relieving qualities in children with acute viral tonsillitis. No patients reported any adverse effects. These preliminary findings are promising; however, the sample size was small and therefore a definitive conclusion cannot be reached. A larger, more inclusive research study should be undertaken to verify the findings of this study.
Personally, I agree only with the latter part of the conclusion and very much doubt that this study was able to “determine the efficacy” of the homeopathic product used. The authors themselves call their trial a “pilot study”. Such projects are not meant to determine efficacy but are usually designed to determine the feasibility of a trial design in order to subsequently mount a definitive efficacy study.
Moreover, I have considerable doubts about the impartiality of the authors. Their affiliation is “Department of Homoeopathy, University of Johannesburg, Johannesburg, South Africa”, and their article was published in a journal known to be biased in favour of homeopathy. These circumstances in itself might not be all that important, but what makes me more than a little suspicious is this sentence from the introduction of their abstract:
“Homeopathic remedies are a useful alternative to conventional medications in acute uncomplicated upper respiratory tract infections in children, offering earlier symptom resolution, cost-effectiveness, and fewer adverse effects.”
A useful alternative to conventional medications (there are no conventional drugs) for earlier symptom resolution?
If it is true that the usefulness of homeopathic remedies has been established, why conduct the study?
If the authors were so convinced of this notion (for which there is, of course, no good evidence) how can we assume they were not biased in conducting this study?
I think that, in order to agree that a homeopathic remedy generates effects that differ from those of placebo, we need a proper (not a pilot) study, published in a journal of high standing by unbiased scientists.
Rigorous research into the effectiveness of a therapy should tell us the truth about the ability of this therapy to treat patients suffering from a given condition — perhaps not one single study, but the totality of the evidence (as evaluated in systematic reviews) should achieve this aim. Yet, in the realm of alternative medicine (and probably not just in this field), such reviews are often highly contradictory.
A concrete example might explain what I mean.
There are numerous systematic reviews assessing the effectiveness of acupuncture for fibromyalgia syndrome (FMS). It is safe to assume that the authors of these reviews have all conducted comprehensive searches of the literature in order to locate all the published studies on this subject. Subsequently, they have evaluated the scientific rigor of these trials and summarised their findings. Finally they have condensed all of this into an article which arrives at a certain conclusion about the value of the therapy in question. Understanding this process (outlined here only very briefly), one would expect that all the numerous reviews draw conclusions which are, if not identical, at least very similar.
However, the disturbing fact is that they are not remotely similar. Here are two which, in fact, are so different that one could assume they have evaluated a set of totally different primary studies (which, of course, they have not).
One recent (2014) review concluded that acupuncture for FMS has a positive effect, and acupuncture combined with western medicine can strengthen the curative effect.
Another recent review concluded that a small analgesic effect of acupuncture was present, which, however, was not clearly distinguishable from bias. Thus, acupuncture cannot be recommended for the management of FMS.
How can this be?
By contrast to most systematic reviews of conventional medicine, systematic reviews of alternative therapies are almost invariably based on a small number of primary studies (in the above case, the total number was only 7 !). The quality of these trials is often low (all reviews therefore end with the somewhat meaningless conclusion that more and better studies are needed).
So, the situation with primary studies of alternative therapies for inclusion into systematic reviews usually is as follows:
- the number of trials is low
- the quality of trials is even lower
- the results are not uniform
- the majority of the poor quality trials show a positive result (bias tends to generate false positive findings)
- the few rigorous trials yield a negative result
Unfortunately this means that the authors of systematic reviews summarising such confusing evidence often seem to feel at liberty to project their own pre-conceived ideas into their overall conclusion about the effectiveness of the treatment. Often the researchers are in favour of the therapy in question – in fact, this usually is precisely the attitude that motivated them to conduct a review in the first place. In other words, the frequently murky state of the evidence (as outlined above) can serve as a welcome invitation for personal bias to do its effect in skewing the overall conclusion. The final result is that the readers of such systematic reviews are being misled.
Authors who are biased in favour of the treatment will tend to stress that the majority of the trials are positive. Therefore the overall verdict has to be positive as well, in their view. The fact that most trials are flawed does not usually bother them all that much (I suspect that many fail to comprehend the effects of bias on the study results); they merely add to their conclusions that “more and better trials are needed” and believe that this meek little remark is sufficient evidence for their ability to critically analyse the data.
Authors who are not biased and have the necessary skills for critical assessment, on the other hand, will insist that most trials are flawed and therefore their results must be categorised as unreliable. They will also emphasise the fact that there are a few reliable studies and clearly point out that these are negative. Thus their overall conclusion must be negative as well.
In the end, enthusiasts will conclude that the treatment in question is at least promising, if not recommendable, while real scientists will rightly state that the available data are too flimsy to demonstrate the effectiveness of the therapy; as it is wrong to recommend unproven treatments, they will not recommend the treatment for routine use.
The difference between the two might just seem marginal – but, in fact, it is huge: IT IS THE DIFFERENCE BETWEEN MISLEADING PEOPLE AND GIVING RESPONSIBLE ADVICE; THE DIFFERENCE BETWEEN VIOLATING AND ADHERING TO ETHICAL STANDARDS.
Some people are their worst enemies, and it seems as though chiropractors are no strangers to this strange phenomenon.
On this blog, I frequently criticise chiropractic; my main concerns are that
- chiropractors make far too many bogus claims far too often,
- there is precious little evidence that their hallmark treatment, spinal manipulation, generates more good than harm.
I repeatedly voice those concerns because I feel strongly that consumers have the right to unbiased information for making evidence-based therapeutic decisions. When I do this, I get invariably attacked by some chiropractors who disagree with me. Frequently, these chiropractors are not interested to discuss the issues I raised with me; instead they insult me in the most primitive way imaginable.
This happens far too often to write about each time, but occasionally things are so extraordinary that I do blog about them. A case in point is the email I recently received out of the blue from “Dr” Brian Moravec, a chiropractor who believes in subluxation and claims that new-born babies should have spinal adjustments. My last post quotes his astonishing views in full; he believes I am a self proclaimed “expert” on alternative medicine, promoting so much misinformation with regard to chiropractic care. Unfortunately he failed to tell me which of my statements he considers to be misleading and he continued: fortunately you look old. and soon will be gone.
Rejoicing at the (hopefully not so) imminent demise of a fellow human being is perhaps not what one might expect from a health care professional. Yet it does fit into the behaviour of chiropractors which tends to turn outright self-destructive when challenged. The comments by chiropractors that followed my post seem to confirm this tendency. They show that the demolition of chiropractic’s reputation by chiropractors is relentless.
One chiropractor claimed Moravec’s opinion could “have been better put”… and “come over as a somewhat personal attack” while quickly changing the subject by starting a discussion on the evidence-base of chiropractic. This ended abruptly in him agreeing with me to disagree. Other chiropractors seemed to concur.
At that stage, one chiropractor noted that Moeavec’s email is doing no favours to the reputation of chiropractic, a ray of light which quickly was instantly overshadowed by a further chiropractor’s comments. This man – or perhaps woman (hiding behind a pseudonym) – is a regular commentator on my blog. He felt that Moravec’s comments were rather polite an opinion which he justified as follows: Dr. Moravec thinks you are old because of your unflattering (IMO) photo. The shiny, bald look adds years to a person’s looks, especially in photos. It is the old glass half-empty or half-full debate. IOW, have you lost hair or have you gained face? The mustache is so fifties, too. The perpetual scowl, however, does suit you rather well. Just sayin’.
At this point, I cannot help but laugh out loud. Someone asked how I can bear those vicious attacks. The answer is that I merely cringe at the stupidity on display. Are these guys really so limited as to not realise what they are doing to their own reputation? Do they not notice that this amounts to a relentless and general demolition of chiropractic’s reputation?
All of this would, of course, be rather trivial fun, if it were a single occurrence – but it is most definitely not!
As I already pointed out, such things happen to me all the time. More remarkably, chiropractors have repeatedly tried to get me fired. Much more importantly, chiropractors have behaved in this way when they decided to sue Simon Singh for libel. Each time, they ended up with plenty of egg on their faces.
Isn’t it time that they learn a lesson? Isn’t it time that they learn to consider criticism seriously? Isn’t it time the more rational one amongst them do something about the many cranks in their midst? Isn’t it time they got their act together?
“Dr” Brian Moravec is a chiropractor from the US; he has a website where he describes himself and his skills as follows: I attended Chiropractic College and I am a graduate of Palmer College of Chiropractic in Davenport Iowa. I earned a Bachelor of Science degree as well as my Doctor of Chiropractic degree from Palmer College, which is the first chiropractic college in the world and the origin of our profession. I also attend continuing education seminars designed to keep doctors current with regard to clinical chiropractic, technique and nutrition.
The key to overall health and wellness is to have a healthy nervous system and that is what I do as a chiropractor – I make sure that your spine is functioning at its best so that your nervous system functions at its best. When the nervous system is functioning at 100%, you are a healthier individual that experiences a higher quality of life and health. I know this to be true in myself, my family and my patients.
I go to great lengths to provide my patients with the best chiropractic care I can give. I work with my patients to design a treatment plan that will be effective for their particular condition and specific to their needs. We utilize manual and low force techniques (safe and effective for newborns to seniors), to correct sublaxations in the spine. Chiropractic adjustments remove nerve interference, which allows the body to perform at its best again. I also am available for consultations on nutrition and diet, dietary supplementation and how to minimize the wear and tear on your spine.
[Emphases are mine]
What he does not state is the fact that he also is a nifty e-mail writer!
To my great surprise, I received an e-mail from him which is far too good to be kept for myself. So I decided to share it with my readers; here it is in its full and unabbreviated beauty:
its interesting to see someone with your education, and is a self proclaimed “expert” on alternative medicine, promote so much misinformation with regard to chiropractic care. fortunately you look old. and soon will be gone. I always refer to the few of you anti chiropractic fools left here as “dinosaurs”. the proof is in the pudding my “friend”. chiropractic works and will continue to be here for centuries more. you and others with much much more power than you (the AMA for example) have tried to perpetuate lies and squash chiropractic. you fail, and they failed, because whatever better serves mankind will stand the test of time. you’re a dying breed edzard. thank God.
yours in health,
brian moravec d.c.
I am encouraged to see that he recognises my education but do wonder why his upbringing obviously failed so dismally teach him even a minimum of politeness, tact, or critical thinking. It is disappointing, I think, that he does not even mention what he perceives as my lies about his beloved chiropractic. So sad, I am sure it would have been fun to debate with him.
One of the problems regularly encountered when evaluating the effectiveness of chiropractic spinal manipulation is that there are numerous chiropractic spinal manipulative techniques and clinical trials rarely provide an exact means of differentiating between them. Faced with a negative studies, chiropractors might therefore argue that the result was negative because the wrong techniques were used; therefore they might insist that it does not reflect chiropractic in a wider sense. Others claim that even a substantial body of negative evidence does not apply to chiropractic as a whole because there is a multitude of techniques that have not yet been properly tested. It seems as though the chiropractic profession wants the cake and eat it.
Amongst the most commonly used is the ‘DIVERSIFIED TECHNIQUE’ (DT) which has been described as follows: Like many chiropractic and osteopathic manipulative techniques, Diversified is characterized by a high velocity low amplitude thrust. Diversified is considered the most generic chiropractic manipulative technique and is differentiated from other techniques in that its objective is to restore proper movement and alignment of spine and joint dysfunction.
Also widely used is a technique called ‘FLEXION DISTRACTION’ (FD) which involves the use of a specialized table that gently distracts or stretches the spine and which allows the chiropractor to isolate the area of disc involvement while slightly flexing the spine in a pumping rhythm.
The ‘ACTIVATOR TECHNIQUE’ (AT) seems a little less popular; it involves having the patient lie in a prone position and comparing the functional leg lengths. Often one leg will seem to be shorter than the other. The chiropractor then carries out a series of muscle tests such as having the patient move their arms in a certain position in order to activate the muscles attached to specific vertebrae. If the leg lengths are not the same, that is taken as a sign that the problem is located at that vertebra. The chiropractor treats problems found in this way moving progressively along the spine in the direction from the feet towards the head. The activator is a small handheld spring-loaded instrument which delivers a small impulse to the spine. It was found to give off no more than 0.3 J of kinetic energy in a 3-millisecond pulse. The aim is to produce enough force to move the vertebrae but not enough to cause injury.
There is limited research comparing the effectiveness of these and the many other techniques used by chiropractors, and the few studies that are available are usually less than rigorous and their findings are thus unreliable. A first step in researching this rather messy area would be to determine which techniques are most frequently employed.
The aim of this new investigation was to do just that, namely to provide insight into which treatment approaches are used most frequently by Australian chiropractors to treat spinal musculoskeletal conditions.
A questionnaire was sent online to the members of the two main Australian chiropractic associations in 2013. The participants were asked to provide information on treatment choices for specific spinal musculoskeletal conditions.
A total of 280 responses were received. DT was the first choice of treatment for most of the included conditions. DT was used significantly less in 4 conditions: cervical disc syndrome with radiculopathy and cervical central stenosis were more likely to be treated with AT. FD was used almost as much as DT in the treatment of lumbar disc syndrome with radiculopathy and lumbar central stenosis. More experienced Australian chiropractors use more AT and soft tissue therapy and less DT compared to their less experienced chiropractors. The majority of the responding chiropractors also used ancillary procedures such as soft tissue techniques and exercise prescription in the treatment of spinal musculoskeletal conditions.
The authors concluded that this survey provides information on commonly used treatment choices to the chiropractic profession. Treatment choices changed based on the region of disorder and whether neurological symptoms were present rather than with specific diagnoses. Diversified technique was the most commonly used spinal manipulative therapy, however, ancillary procedures such as soft tissue techniques and exercise prescription were also commonly utilised. This information may help direct future studies into the efficacy of chiropractic treatment for spinal musculoskeletal disorders.
I am a little less optimistic that this information will help to direct future research. Critical readers might have noticed that the above definitions of two commonly used techniques are rather vague, particularly that of DT.
Why is that so? The answer seems to be that even chiropractors are at a loss coming up with a good definition of their most-used therapeutic techniques. I looked hard for a more precise definition but the best I could find was this: Diversified is characterized by the manual delivery of a high velocity low amplitude thrust to restricted joints of the spine and the extremities. This is known as an adjustment and is performed by hand. Virtually all joints of the body can be adjusted to help restore proper range of motion and function. Initially a functional and manual assessment of each joint’s range and quality of motion will establish the location and degree of joint dysfunction. The patient will then be positioned depending on the region being adjusted when a specific, quick impulse will be delivered through the line of the joint in question. The direction, speed, depth and angles that are used are the product of years of experience, practice and a thorough understanding of spinal mechanics. Often a characteristic ‘crack’ or ‘pop’ may be heard during the process. This is perfectly normal and is nothing to worry about. It is also not a guide as to the value or effectiveness of the adjustment.
This means that the DT is not a single method but a hotchpotch of techniques; this assumption is also confirmed by the following quote: The diversified technique is a technique used by chiropractors that is composed of all other techniques. It is the most commonly used technique and primarily focuses on spinal adjustments to restore function to vertebral and spinal problems.
What does that mean for research into chiropractic spinal manipulation? It means, I think, that even if we manage to define that a study was to test the effectiveness of one named chiropractic technique, such as DT, the chiropractors doing the treatments would most likely do what they believe is required for each individual patient.
There is, of course, nothing wrong with that approach; it is used in many other area of health care as well. In such cases, we need to view the treatment as something like a ‘black box'; we test the effectiveness of the black box without attempting to define its exact contents, and we trust that the clinicians in the trial are well-trained to use the optimal mix of techniques as needed for each individual patient.
I would assume that, in most studies available to date, this is precisely what already has been implemented. It is simply not reasonable to assume that a trial the trialists regularly instructed the chiropractors not to use the optimal treatments.
What does that mean for the interpretation of the existing trial evidence? It means, I think, that we should interpret it on face value. The clinical evidence for chiropractic treatment of most conditions fails to be convincingly positive. Chiropractors often counter that such negative findings fail to take into account that chiropractors use numerous different techniques. This argument is not valid because we must assume that in each trial the optimal techniques were administered.
In other words, the chiropractic attempt to have the cake and eat it has failed.
Influenza kills thousands of people every year. Immunisation could prevent many of these deaths. Those at particularly high risk, e.g. young children, individuals aged 65 and older and people with severe diseases in their medical history, are therefore encouraged to get immunised. Nova Scotia health officials have just started their annual flu shot campaign. Now they are warning about some anti-flu vaccine literature being distributed by a chiropractor.
The leaflets from local chiropractic clinics suggest that flu shots increase the risk of a child ending up in hospital and link Alzheimer’s disease to flu shots. When questioned about this, the chair of the Nova Scotia College of Chiropractors defended this misinformation and claimed the author of the pamphlet did his homework. “Chiropractic is really pro information. Look at the positive, look at the negative, look at both sides, get your information and make the appropriate decision that’s right for you,” he said.
However, Dr. Robert Strang, Nova Scotia’s chief public health officer, said the message is wrong and added that the pamphlet is not based on medicine and is confusing to the public. “It’s discouraging, but unfortunately there are a range of what I call alternative-medicine practitioners who espouse a whole bunch of views which aren’t evidence based,” he said.
The stance of many chiropractors against immunisations is well known and has long historical roots. Campbell and colleagues expressed this clearly: Although there is overwhelming evidence to show that vaccination is a highly effective method of controlling infectious diseases, a vocal element of the chiropractic profession maintains a strongly antivaccination bias… The basis seems to lie in early chiropractic philosophy, which, eschewing both the germ theory of infectious disease and vaccination, considered disease the result of spinal nerve dysfunction caused by misplaced (subluxated) vertebrae. Although rejected by medical science, this concept is still accepted by a minority of chiropractors. Although more progressive, evidence-based chiropractors have embraced the concept of vaccination, the rejection of it by conservative chiropractors continues to have a negative influence on both public acceptance of vaccination and acceptance of the chiropractic profession by orthodox medicine.
No doubt, there will be comments following this post claiming that many chiropractors have now learnt their lesson and have considerably revised their stance on vaccination. This may well be true. But far too many chiropractors still post hair-raising nonsense about vaccination. Take this guy, for instance, who concludes his article (just one example of many) on the subject with this revealing paragraph: Our original blood was good enough. What a thing to say about one of the most sublime substances in the universe. Our original professional philosophy was also good enough. What a thing to say about the most evolved healing concept since we crawled out of the ocean. Perhaps we can arrive at a position of profound gratitude if we could finally appreciate the identity, the oneness, the nobility of an uncontaminated unrestricted nervous system and an inviolate bloodstream. In such a place, is not the chiropractic position on vaccines self-evident, crystal clear, and as plain as the sun in the sky?
As long as dangerous cranks are tolerated by the vast majority of chiropractors and their professional organisations to mislead the public, I have to agree with Dr Strang: “It’s discouraging, but unfortunately there are a range of what I call alternative-medicine practitioners who espouse a whole bunch of views which aren’t evidence based.”
A reader of this blog recently sent me the following message: “Looks like this group followed you recent post about how to perform a CAM RCT!” A link directed me to a new trial of ear-acupressure. Today is ‘national acupuncture and oriental medicine day’ in the US, a good occasion perhaps to have a critical look at it.
The aim of this study was to assess the effectiveness of ear acupressure and massage vs. control in the improvement of pain, anxiety and depression in persons diagnosed with dementia.
For this purpose, the researchers recruited a total of 120 elderly dementia patients institutionalized in residential homes. The participants were randomly allocated, to three groups:
- Control group – they continued with their routine activities;
- Ear acupressure intervention group – they received ear acupressure treatment (pressure was applied to acupressure points on the ear);
- Massage therapy intervention group – they received relaxing massage therapy.
Pain, anxiety and depression were assessed with the Doloplus2, Cornell and Campbell scales. The study was carried out during 5 months; three months of experimental treatment and two months with no treatment. The assessments were done at baseline, each month during the treatment and at one and two months of follow-up.
A total of 111 participants completed the study. The ear acupressure intervention group showed better improvements than the two other groups in relation to pain and depression during the treatment period and at one month of follow-up. The best improvement in pain was achieved in the last (3rd) month of ear acupressure treatment. The best results regarding anxiety were also observed in the last month of treatment.
The authors concluded that ear acupressure and massage therapy showed better results than the control group in relation to pain, anxiety and depression. However, ear acupressure achieved more improvements.
The question is: IS THIS A RIGOROUS TRIAL?
My answer would be NO.
Now I better explain why, don’t I?
If we look at them critically, the results of this trial might merely prove that spending some time with a patient, being nice to her, administering a treatment that involves time and touch, etc. yields positive changes in subjective experiences of pain, anxiety and depression. Thus the results of this study might have nothing to do with the therapies per se.
And why would acupressure be more successful than massage therapy? Massage therapy is an ‘old hat’ for many patients; by contrast, acupressure is exotic and relates to mystical life forces etc. Features like that have the potential to maximise the placebo-response. Therefore it is conceivable that they have contributed to the superiority of acupressure over massage.
What I am saying is that the results of this trial can be interpreted in not just one but several ways. The main reason for that is the fact that the control group were not given an acceptable placebo, one that was indistinguishable from the real treatment. Patients were fully aware of what type of intervention they were getting. Therefore their expectations, possibly heightened by the therapists, determined the outcomes. Consequently there were factors at work which were totally beyond the control of the researchers and a clear causal link between the therapy and the outcome cannot be established.
An RCT that is aimed to test the effectiveness of a therapy but fails to establish such a causal link beyond reasonable doubt cannot be characterised as a rigorous study, I am afraid.
Sorry! Did I spoil your ‘national acupuncture and oriental medicine day’?
