Swiss chiropractors have just published a clinical trial to investigate outcomes of patients with radiculopathy due to cervical disk herniation (CDH). All patients had neck pain and dermatomal arm pain; sensory, motor, or reflex changes corresponding to the involved nerve root and at least one positive orthopaedic test for cervical radiculopathy were included. CDH was confirmed by magnetic resonance imaging. All patients received regular neck manipulations.
Baseline data included two pain numeric rating scales (NRSs), for neck and arm, and the Neck Disability Index (NDI). At two, four and twelve weeks after the initial consultation, patients were contacted by telephone, and the data for NDI, NRSs, and patient’s global impression of change were collected. High-velocity, low-amplitude thrusts were administered by experienced chiropractors. The proportion of patients reporting to feel “better” or “much better” on the patient’s global impression of change scale was calculated. Pre-treatment and post-treatment NRSs and NDIs were analysed.
Fifty patients were included. At two weeks, 55.3% were “improved,” 68.9% at four and 85.7% at twelve weeks. Statistically significant decreases in neck pain, arm pain, and NDI scores were noted at 1 and 3 months compared with baseline scores. 76.2% of all sub-acute/chronic patients were improved at 3 months.
The authors concluded that most patients in this study, including sub-acute/chronic patients, with symptomatic magnetic resonance imaging-confirmed CDH treated with spinal manipulative therapy, reported significant improvement with no adverse events.
In the presence of disc herniation, chiropractic manipulations have been described to cause serious complications. Some experts therefore believe that CDH is a contra-indication for spinal manipulation. The authors of this study imply, however, that it is not – on the contrary, they think it is an effective intervention for CDH.
One does not need to be a sceptic to notice that the basis for this assumption is less than solid. The study had no control group. This means that the observed effect could have been due to:
a placebo response,
the regression towards the mean,
the natural history of the condition,
or other factors which have nothing to do with the chiropractic intervention per se.
And what about the interesting finding that no adverse-effects were noted? Does that mean that the treatment is safe? Sorry, but it most certainly does not! In order to generate reliable results about possibly rare complications, the study would have needed to include not 50 but well over 50 000 patients.
So what does the study really tell us? I have pondered over this question for some time and arrived at the following answer: NOTHING!
Is that a bit harsh? Well, perhaps yes. And I will revise my verdict slightly: the study does tell us something, after all – chiropractors tend to confuse research with the promotion of very doubtful concepts at the expense of their patients. I think, there is a name for this phenomenon: PSEUDO-SCIENCE.
Chiropractors across the world tend to make false claims. This has been shown with such embarrassing regularity that there is no longer any question about it. Should someone have the courage to disclose and criticises this habit, chiropractors tend to attack their critic, rather than putting their house in order. One of their more devious strategies, in my view, is their insistence on claiming to effectively treat all sorts of childhood conditions.
What could be more evil than treating sick children with ineffective and harmful spinal manipulations? The answer is surprisingly simple: PREVENTING CHILDREN FROM PROFITTING FROM ONE OF THE MOST BENEFICIAL INTERVENTIONS EVER DISCOVERED!
The National Vaccine Information Center (NVIC) is an organisation which seems to support anti-vaxers of various kinds. Officially they try hard to give the image of being neutral about vaccinations and state that they are dedicated to the prevention of vaccine injuries and deaths through public education and to defending the informed consent ethic in medicine. As an independent clearinghouse for information on diseases and vaccines, NVIC does not advocate for or against the use of vaccines. We support the availability of all preventive health care options, including vaccines, and the right of consumers to make educated, voluntary health care choices.
In my view, this is thinly disguised promotion of an anti-vaccination stance. The NVIC recently made the following announcement:
The International Chiropractic Pediatric Association (ICPA), which was founded by Dr. Larry Webster and represents doctors of chiropractic caring for children, has supported NVIC’s mission to prevent vaccine injuries and deaths through public education and to protect informed consent rights for more than two decades. ICPA’s 2013 issue of Pathways to Family Wellness magazine features an article written by Barbara Loe Fisher on “The Moral Right to Religious and Conscientious Belief Exemptions to Vaccination.”
Pathways to Family Wellness is a full-color, quarterly publication that offers parents timely, relevant information about health and wellness options that will help them make conscious health choices for their families. ICPA offers NVIC donor supporters and NVIC Newsletter subscribers a complimentary digital version or print version of Pathways to Family Wellness magazine at a significant discount. Visit the Pathways subscription page and, when checking out in the shopping cart, add the exclusive code: NVIC.
ICPA also has initiated parenting support groups that meet monthly to discuss health and parenting topics. Meetings are hosted by local doctors of chiropractic and the Pathways website features a directory of local groups. ICPA Executive Director Dr. Jeanne Ohm said “We look forward to many more years of collaborating with NVIC to forward our shared goal of enhancing and protecting the ability of parents to make fully informed health and wellness choices for their children.”
Why, we may well ask, are so many chiropractors against immunisations? The answer might be found in the history of chiropractic. Their founding fathers believed and taught that “subluxations” are the cause of all human diseases. To uphold this ridiculous creed, it was necessary to deny that infections play an important role in many illnesses. In other words, early chiropractors negated the germ theory of disease. Today, of course, they claim that all of this is ancient history – but the stance of many chiropractors against immunisations discloses fairly clearly, I think, that this is not true. Many chiropractic institutions still teach obsolete pseudo-knowledge and many chiropractors seem unable to totally free themselves from such obvious nonsense.
But back to the ICPA: they profess to be a non-profit organization whose mission is to engage and serve family chiropractors worldwide through education, training, and research, establishing evidenced informed practice, excellence in professional skills and unity in a global community which cooperatively and enthusiastically participates in advancing chiropractic for both the profession and the public.
What does “evidence informed practice” mean? This bizarre creation is alarmingly popular with quacks of all kinds and seems to aim at misleading the unsuspecting public. It clearly has little to do with EVIDENCE-BASED PRACTICE as globally adopted by responsible clinicians. If not, the ICPA would inform its members and the public at large that immunisations are amongst the most successful preventive measures in the history of medicine. It is hard to think of another medical intervention where the benefits so clearly and hugely outweigh the risks. Immunisations have saved more lives than most other medical treatments. To not make this crystal clear to concerned parents is, in my view, wholly irresponsible.
Researchers from the ‘Complementary and Integrative Medicine Research, Primary Medical Care, University of Southampton’ conducted a study of Professional Kinesiology Practice (PKP) What? Yes, PKP! This is a not widely known alternative method.
According to its proponents, it is unique and a complete kinesiology system… It was developed by a medical doctor, Dr Bruce Dewe and his wife Joan Dewe in the 1980s and has been taught since then in over 16 countries around the world with great success… Kinesiology is a unique and truly holistic science and on the cutting edge of energy medicine. It uses muscle monitoring as a biofeedback system to identify the underlying cause of blockage from the person’s subconscious mind via the nervous system. Muscle monitoring is used to access information from the person’s “biocomputer”, the brain, in relation to the problem or issue and also guides the practitioner to find the priority correction in order to stimulate the person’s innate healing capacity and support their physiology to return to normal function. Kinesiology is unique as it looks beyond symptoms. It recognizes the flows of energy within the body not only relate to the muscles but to every tissue and organ that make the human body a living ever changing organism. These energy flows can be evaluated by testing the function of the muscles, which in turn reflect the body’s overall state of structural, chemical, emotional and spiritual balance. In this way kinesiology taps into energies that the more conventional modalities overlook and helps remove all the guesswork, doubt and hard work of subjective diagnostics. This is a revolutionary way to communicate with the body/mind connection. Through muscle monitoring and the use of over 300 fingermodes we can detect and correct the cause of the problem and effect a long lasting change for better health and wellbeing. Our posture could be considered to be the visual display unit from our internal bio-computer. Our posture / life energy improves as we upgrade the way we respond to life’s constant challenges and demands.
You do not understand? Let me make it crystal clear by citing another PKP-site:
PKP is a phenomenological practice – this means practitioners use manual muscle testing to demonstrate to the client how much or how little they are able to move in relation to their problem. PKP practitioners have tests for more than 100 muscles, and dozens of other tests that they do so they can clearly show you how your movement is affected by your problem. This muscle story shows a person how their life is unfolding, and it also helps to guide on how to transcend the situation and design a future which is more in alignment with nature and the laws of the cosmos… PKP is about living life more wisely.
According to its authors, it was an exploratory, pragmatic single-blind, 3-arm randomised sham-controlled pilot trial with waiting list control (WLC) which was conducted in the setting of a UK private practice. Seventy participants scoring ≥4 on the Roland and Morris Disability Questionnaire (RMDQ) were randomised to real or sham PKP receiving one treatment weekly for 5 weeks or a WLC. WLC’s were re-randomised to real or sham after 6 weeks. The main outcome measure was a change in RMDQ from baseline to end of 5 weeks of real or sham PKP.
The results show an effect size of 0.7 for real PKP which was significantly different to sham. Compared to WLC, both real and sham groups had significant RMDQ improvements. Practitioner empathy (CARE) and patient enablement (PEI) did not predict outcome; holistic health beliefs (CAMBI) did, though. The sham treatment appeared credible; patients did not guess treatment allocation. Three patients reported minor adverse reactions.
From these data, the authors conclude that real treatment was significantly different from sham demonstrating a moderate specific effect of PKP; both were better than WLC indicating a substantial non-specific and contextual treatment effect. A larger definitive study would be appropriate with nested qualitative work to help understand the mechanisms involved in PKP.
So, PKP has a small specific effect in addition to generating a sizable placebo-effect? Somehow, I doubt it! This was, according to its authors, a pilot study. Such an investigation should not evaluate the effectiveness of a treatment but the feasibility of the protocol. Even if we disregard this detail, I assume that the results indicate the effects of PKP to be essentially due to placebo. The small effect which the authors label as “specific” is, in my view, almost certainly caused by residual confounding and hidden biases.
One could also go one step further and say that any treatment that is shrouded in pseudo-scientific language and has zero plausibility is an ill-conceived candidate for a clinical trial of this nature. If it should be tested at all – and thus cost money, effort and patient-participation – a rigorous study should be designed and conducted not by apologists of the intervention but by more level-headed scientists.
In a recent comment, US chiropractors stated that there is a growing recognition within the profession that the practicing chiropractor must be able to do the following: formulate a searchable clinical question, rapidly access the best evidence available, assess the quality of that evidence, determine if it is applicable to a particular patient or group of patients, and decide if and how to incorporate the evidence into the care being offered. In a word, they believe, that evidence-based chiropractic is possible, perhaps even (almost) a reality. For evidence-based practice to penetrate and transform a profession, the penetration must occur at two levels, they explain. One level is the degree to which individual practitioners possess the willingness and basic skills to search and assess the literature.
The second level, the authors explain, relates to whether the therapeutic interventions commonly employed by a particular health care discipline are supported by clinical research. The authors believe that a growing body of randomized controlled trials provides evidence of the effectiveness and safety of manual therapies. Is this really true, I wonder.
In support of these fairly bold statements, they cite a paper by Bronfort et al which, in their view, is currently the most comprehensive review of the evidence for the efficacy of manual therapies. According to these authors, the ‘Bronfort-report’ stated that evidence is inconclusive for pneumonia, stage 1 hypertension, pre-menstrual syndrome, nocturnal enuresis, and otitis media. The authors also believe that it is unlikely manipulation of the neck is causally related to stroke.
When I read this article, I could not stop myself from giggling. It seems to me that it provides pretty good evidence for the fact that the chiropractic profession is nowhere near reaching the stage where anyone could reasonably claim that chiropractors practice evidence-based medicine – not even the authors themselves seem to abide by the rules of evidence-based medicine! If they had truly been able to access the best evidence available and assess the quality of that evidence surely they would not have (mis-) quoted the ‘Bronfort-report’.
Bronfort’s overview was commissioned by the General Chiropractic Council, it was hastily compiled by ardent believers of chiropractic, published in a journal that non-chiropractors would not touch with a barge pole, and crucially it lacks some of the most important qualities of an unbiased systematic review. In my view, it is nothing short of a white-wash and not worth the paper it was printed on. Conclusions, such as the evidence regarding pneumonia, bed-wetting and otitis is inconclusive are just embarrassing; the correct conclusion is that the evidence fails to be positive for these and most other indications.
Similarly, if the authors had really studied and quoted the best evidence, how on earth could they have stated that manipulation of the neck cannot cause a stroke? The evidence for that is fairly overwhelming, and the only open question here is, how often do such complications occur? And even the biased ‘Bronfort-report’ states: Adverse events associated with manual treatment can be classified into two categories: 1) benign, minor or non-serious and 2) serious. Generally those that are benign are transient, mild to moderate in intensity, have little effect on activities, and are short lasting. Most commonly, these involve pain or discomfort to the musculoskeletal system. Less commonly, nausea, dizziness or tiredness are reported. Serious adverse events are disabling, require hospitalization and may be life-threatening. The most documented and discussed serious adverse event associated with spinal manipulation (specifically to the cervical spine) is vertebrobasilar artery (VBA) stroke. Less commonly reported are serious adverse events associated with lumbar spine manipulation, including lumbar disc herniation and cauda equina syndrome.
Evidence-based practice? Who are these chiropractors kidding? This article very neatly reflects the exact opposite. It ignores hundreds of peer-reviewed papers which are critical of chiropractic. The best one can do with this paper, I think, is to use it as a hilarious bit of involuntary humour or as a classic example of cherry-picking.
Come to think of it, chiropractic and evidence-based practice are contradictions in terms. Either a therapist claims to adjust mystical subluxations, in which case he/she does not practice evidence-based medicine. Or he/she practices evidence-based medicine, in which case adjusting mystical subluxations cannot be part of their therapeutic repertoire.
Towards the end of the article, we learn further fascinating things: the authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article – oh, really?!?! Furthermore, we are told that this ‘research’ was funded by the ‘National Center of Complementary and Alternative Medicine’ (NCCAM) of the National Institutes of Health.
Can it be true? Does the otherwise most respectable NIH really give its name for such overt nonsense? Yes, it is true, and it is by no means the first time. In fact, our analysis shows that, when it comes to chiropractic, this organisation has sponsored almost nothing but utter rubbish, and our conclusion was blunt: the criticism repeatedly aimed at NCCAM seems justified, as far as their RCTs of chiropractic is concerned. It seems questionable whether such research is worthwhile.
According to its proponents, Vibrational Medicine (VM) is a healing system that uses the ancient art of dowsing to identify the cause of a disease (or dis-harmony in the body). This therapy is a meeting of eastern and western forms of healing since we often use a western understanding of the body and how it functions and combine this with the eastern practice of rebalancing energies within the body to bring about healing. Sometimes the actual cause of a disease can appear to be far removed from the apparent symptoms when taking the western viewpoint. However everything is connected and especially so within the body. The body is always striving to heal itself but sometimes it can get ‘blocked’. These ‘blocks’ can be caused by many things including biochemicals, toxins, emotions, viruses, parasites or bacteria. The main aim of vibrational medicine is to clear these ‘blocks’ to allow the body to function correctly.
I am intrigued and surprised; for instance, I had no idea that there is such a thing as a western understanding of the body and how it functions. But what does this mean? How does VM work? The answer seems simpler than you may have thought: VM works by rebalancing the minute vibrational frequencies that make up the energy field within the atoms, molecules, organs and systems within the body. A block or a disharmony within the body can be thought of as being like an orchestra with an instrument that is not tuned correctly. The remedies applied are then ‘re-tuning’ the body’s energy so that the body (the orchestra) plays a more harmonious tune again.
I see, that is impressive! And what diseases can be treated with VM? Don’t tell me it is a panacea! Yes, it is: Because vibrational medicine can work on many levels within the body (for instance it can work on the aura and chakras, the cellular level or it can work on particular organs or systems within the body) it can therefore be used to treat any condition that affects the mind or body of any person or animal.
How utterly miraculous! But in case you find this too vague and not sufficiently technical, here is a more scientific explanation from a different source: The term ‘vibrational’ is connected to the field of Quantum Physics where it is found that all living beings (people, animals and plants) have a unique vibrational frequency or energy field. Kilian photography is one of several scientific methods which have illustrated the existence of this field. If one picks a leaf from a tree and applies a high voltage to its energy field, it can be photographed and observed. As the leaf dies the field becomes smaller until it disappears when it is dead. Also, a ‘quantum’ of energy is released by an atom when it reaches a stable state. This is unique to that particular atom.
I did suspect that quantum physics had to be involved. This is as good as it gets! I am sure you are as fascinated as I am and keen to learn more. The exciting news is that, at the Scottish School of Vibrational Medicine, you can complete your knowledge to diploma-level: This course will cover the major range of topics covered in the course of obtaining the Diploma in Vibrational Medicine and is a “broad brush” coverage of the whole course. During the course specialist and unique Homeopathic remedies will be used and students will take some remedies home with them to try at leisure the working of these remedies.
Now I understand; VM seems to be a bit of homeopathy, naturopathy, spiritual healing all mixed together. Sounds convincing – wait until our Health Secretary hears about this one! The NHS might never be the same again.
A cult can be defined not just in a religious context, but also as a” usually nonscientific method or regimen claimed by its originator to have exclusive or exceptional power in curing a particular disease.” After ~20 years of researching this area, I have come to suspect that much of alternative medicine resembles a cult – a bold statement, so I better explain.
One characteristic of a cult is the unquestioning commitment of its members to the bizarre ideas of their iconic leader. This, I think, chimes with several forms alternative medicine. Homeopaths, for instance, very rarely question the implausible doctrines of Hahnemann who, to them, is some sort of a semi-god. Similarly, few chiropractors doubt even the most ridiculous assumptions of their founding father, D D Palmer who, despite of having been a somewhat pathetic figure, is uncritically worshipped. By definition, a cult-leader is idealised and thus not accountable to anyone; he (yes, it is almost invariably a male person) cannot be proven wrong by logic arguments nor by scientific facts. He is quite simply immune to any form of scrutiny. Those who dare to disagree with his dogma are expelled, punished, defamed or all of the above.
Cults tend to brain-wash their members into unconditional submission and belief. Likewise, fanatics of alternative medicine tend to be brain-washed, i.e. systematically misinformed to the extend that reality becomes invisible. They unquestioningly believe in what they have been told, in what they have read in their cult-texts, and in what they have learnt from their cult-peers. The effects of this phenomenon can be dramatic: the powers of discrimination of the cult-member are reduced, critical questions are discouraged, and no amount of evidence can dissuade the cult-member from abandoning even the most indefensible concepts. Internal criticism is thus by definition non-existent.
Like religious cults, many forms of alternative medicine promote an elitist concept. Cult-members become convinced of their superiority, based not on rational considerations but on irrational beliefs. This phenomenon has a range of consequences. It leads to the isolation of the cult-member from the rest of the world. By definition, critics of the cult do not belong to the elite; they are viewed as not being able to comprehend the subtleties of the issues at hand and are thus ignored or not taken seriously. For cult-members, external criticism is thus non-existent or invalid.
Cult-members tend to be on a mission, and so are many enthusiasts of alternative medicine. They use any conceivable means to recruit new converts. For instance, they try to convince family, friends and acquaintances of their belief in their particular alternative therapy at every conceivable occasion. They also try to operate on a political level to popularize their cult. They cherry pick data, often argue emotionally rather than rationally, and ignore all arguments which contradict their belief system.
Cult-members, in their isolation from society, tend to be assume that there is little worthy of their consideration outside the cult. Similarly, enthusiasts of alternative medicine tend to think that their treatment is the only true method of healing. Therapies, concepts and facts which are not cult-approved are systematically defamed. An example is the notion of BIG PHARMA which is employed regularly in alternative medicine. No reasonable person assumes that the pharmaceutical industry smells of roses. However, the exaggerated and systematic denunciation of this industry and its achievements is a characteristic of virtually all branches of alternative medicine. Such behaviour usually tells us more about the accuser than the accused.
There are many other parallels between a cult and alternative medicine, I am sure. In my view, the most striking one must be the fact that any spark of cognitive dissonance in the cult-victim is being extinguished by highly effective and incessant flow of misinformation which often amounts to a form of brain-washing.
The main aim of our systematic review was to estimate the prevalence of use of alternative medicine (AM) in the UK. Five databases were searched for peer-reviewed surveys published between 1 January 2000 and 7 October 2011. In addition, relevant book chapters and files from our own departmental records were searched by hand. Eighty-nine surveys were included, with a total of 97,222 participants. Surely, fact that this large amount of UK surveys had emerged in only about one decade, speaks for itself.
Most studies turned out to be of poor methodological quality. Across all surveys, the average one-year prevalence of AM-use was 41.1%, and the average lifetime prevalence was 51.8%. However, many of these investigations were flimsy. According to methodologically sound surveys, the equivalent rates were 26.3% and 44%, respectively. In surveys with response rates >70%, the average one-year prevalence was nearly threefold lower than in surveys with response rates below 50%. Herbal medicine was the most popular CAM, followed by homeopathy, aromatherapy, massage and reflexology.
To the best of my knowledge, this is the first time that four crucial points about such surveys have been clearly documented:
1) The amount of surveys in AM is staggering.
2) They contribute very little worthwhile knowledge and mostly seem to be exercises in AM-promotion.
3) Their methodological quality is usually low.
4) The poor quality surveys systematically over-estimate the prevalence of AM-use.
I think it is time that AM investigators focus on real research answering important questions which advance out knowledge, that AM-journal editors stop publishing meaningless nonsense, and that decision-makers understand the difference between promotion dressed up as science and real research.
Even after all these years of full-time research into alternative medicine and uncounted exchanges with enthusiasts involved in this sector, I find the logic that is often applied in this field bewildering and the unproductiveness of the dialogue disturbing.
To explain what I mean, it be might best to publish a (fictitious, perhaps slightly exaggerated) debate between a critical thinker or scientist (S) and an uncritical proponent (P) of one particular form of alternative medicine.
P: Did you see this interesting study demonstrating that treatment X is now widely accepted, even by highly critical GPs at the cutting edge of health care?
S: This was a survey, not a ‘study’, and I never found the average GP “highly critical”. Surveys of this nature are fairly useless and they “demonstrate” nothing of real value.
P: Whatever, but it showed that GPs accept treatment X. This can only mean that they realise how safe and effective it is.
S: Not necessarily, GPs might just give in to consumer demand, or the sample was cleverly selected, or the question was asked in a leading manner, etc.
P: Hardly, because there is plenty of good evidence for treatment X.
S: Really? Show me.
P: There is this study here which proves that treatment X works and is risk-free.
S: The study was far too small to demonstrate safety, and it is wide open to multiple sources of bias. Therefore it does not conclusively show efficacy either.
P: You just say this because you don’t like its result! You have a closed mind!
In any case, it was merely an example! There are plenty more positive studies; do your research properly before you talk such nonsense.
S: I did do some research and I found a recent, high quality systematic review that arrived at a negative conclusion about the value of treatment X.
P: That review was done by sceptics who clearly have an axe to grind. It is based on studies which do not account for the intrinsic subtleties of treatment X. Therefore they are unfair tests of treatment X. These trials don’t really count at all. Every insider knows that! The fact that you cite it merely confirms that you do not understand what you are talking about.
S: It seems to me, that you like scientific evidence only when it confirms your belief. This, I am afraid, is what quacks tend to do!
P: I strongly object to being insulted in this way.
S: I did not insult you, I merely made a statement of fact.
P: If you like facts, you have to see that one needs to have sufficient expertise in treatment X in order to apply it properly and effectively. This important fact is neglected in all of those trials that report negative results; and that’s why they are negative. Simple! I really don’t understand why you are too stupid to understand this. Such studies do not show that treatment X is ineffective, but they demonstrate that the investigators were incompetent or hired with the remit to discredit treatment X.
S: I would have thought they are negative because they minimised bias and the danger of generating a false positive result.
P: No, by minimising bias, as you put it, these trials eliminated the factors that are important elements of treatment X.
S: Such as the placebo-effect?
P: That’s what you call it because you irrationally believe in reductionist science.
S: Science requires no belief, I think you are the believer here.
P: The fact is that scientists of your ilk negate all factors related to human interactions. Patients are no machines, you know, they need compassion; we clinicians know that because we work at the coal face of health care. Scientists in their ivory towers have no idea about patient care and just want science for science sake. This is not how you help patients. Show some compassion man!
S: I do know about the importance of compassion and care, but here we are discussing an entirely different topic, namely tests the efficacy or effectiveness of treatments, not patient-care. Let’s focus on one issue at a time.
P: You cannot separate things in this way. We have to take a holistic view. Patients are whole individuals, and you cannot do them justice by running artificial experiments. Every patient is different; clinical trials fail to account for this fact and are therefore fairly irrelevant to us and to our patients. Real life is very different from your imagined little experiments, you know.
S: These are platitudes that are nonsensical in this context and do not contribute anything meaningful to the present discussion. You do not seem to understand the methodology or purpose of a clinical trial.
P: That is typical! Whenever you run out of arguments, you try to change the subject or throw a few insults at me.
S: Not at all, I thought we were talking about clinical trials evaluating the effectiveness of treatment X.
P: That’s right; and they do show that it is effective, provided you consider those which are truly well-done by experts who know about treatment X and believe in it.
S: Not true. Only if you cherry-pick the data will you be able to produce an overall positive result for treatment X.
P: In any case, the real world results of clinical practice show very clearly that it works. It would not have survived for so long, if it didn’t. Nobody can deny that, and nobody should claim that silly little trials done in artificial circumstances are more meaningful than a wealth of experience.
S: Experience has little to do with reliable evidence.
P: To deny the value of experience is just stupid and clearly puts you in the wrong. I have shown you plenty of reliable evidence but you just ignore everything I say that does not go along with your narrow-minded notions about science; science is not the only way of knowing or comprehending things! Stop being obsessed with science.
S: No, you show me rubbish data and have little understanding of science, I am afraid.
P: Here we go again! I have had about enough of that and your blinkered arguments. We are going in circles because you are ignorant and arrogant. I have tried my best to show you the light, but your mind is closed. I offer true insight and you pay me back with insults. You and your cronies are in the pocket of BIG PHARMA. You are cynical, heartless and not interested in the wellbeing of patients. Next you will tell me to vaccinate my kids!
S: I think this is a waste of time.
P: Precisely! Everyone who has followed this debate will see very clearly that you are obsessed with reductionist science and incapable of considering the suffering of whole individuals. You want to deny patients a treatment that really helps them simply because you do not understand how treatment X works. Shame on you!!!
Reiki is a form of healing which rests on the assumption that some form “energy” determines our health. In this context, I tend to put energy in inverted commas because it is not the energy a physicist might have in mind. It is a much more mystical entity, a form of vitality that is supposed to be essential for life and keep us going. Nobody has been able to define or quantify this “energy”, it defies scientific measurement and is biologically implausible. These circumstances render Reiki one of the least plausible therapies in the tool kit of alternative medicine.
Reiki-healers (they prefer to be called “masters”) would channel “energy” into his or her patient which, in turn, is thought to stimulate the healing process of whatever condition is being treated. In the eyes of those who believe in this sort of thing, Reiki is therefore a true panacea: it can heal everything.
The clinical evidence for or against Reiki is fairly clear – as one would expect after realising how ‘far out’ its underlying concepts are. Numerous studies are available, but most are of very poor quality. Their results tend to suggest that patients experience benefit after having Reiki but they rarely exclude the possibility that this is due to placebo or other non-specific effects. Those that are rigorous show quite clearly that Reiki is a placebo. Our own review therefore concluded that “the evidence is insufficient to suggest that Reiki is an effective treatment for any condition… the value of Reiki remains unproven.”
Since the publication of our article, a number of new investigations have become available. In a brand-new study, for instance, the researchers wanted to explore a Reiki therapy-training program for the care-givers of paediatric patients. A series of Reiki training classes were offered by a Reiki-master. At the completion of the program, interviews were conducted to elicit participant’s feedback regarding its effectiveness.
Seventeen families agreed to participate and 65% of them attended three Reiki training sessions. They reported that Reiki had benefited their child by improving their comfort (76%), providing relaxation (88%) and pain relief (41%). All caregivers thought that becoming an active participant in their child’s care was a major gain. The authors of this investigation conclude that “a hospital-based Reiki training program for caregivers of hospitalized pediatric patients is feasible and can positively impact patients and their families. More rigorous research regarding the benefits of Reiki in the pediatric population is needed.”
Trials like this one abound in the parallel world of “energy” medicine. In my view, such investigations do untold damage: they convince uncritical thinkers that “energy” healing is a rational and effective approach – so much so that even the military is beginning to use it.
The flaws in trials as the one above are too obvious to mention. Like most studies in this area, this new investigation proves nothing except the fact that poor quality research will mislead those who believe in its findings.
Some might say, so what? If a patient experiences benefit from a bogus yet harmless therapy, why not? I would strongly disagree with this increasingly popular view. Reiki and similarly bizarre forms of “energy” healing are well capable of causing harm.
Some fanatics might use these placebo-treatments as a true alternative to effective therapies. This would mean that the condition at hand remains untreated which, in a worst case scenario, might even lead to the death of patients. More important, in my view, is an entirely different risk: making people believe in mystic “energies” undermines rationality in a much more general sense. If this happens, the harm to society would be incalculable and extends far beyond health care.
Five years ago to the day, Simon Singh and I published an article in The Daily Mail to promote our book TRICK OR TREATMENT… which was then about to be launched. We recently learnt that our short article prompted a “confidential” message by the BRITISH CHIROPRACTIC ASSOCIATION to all its members. “Confidential” needs to be put in inverted commas because it is readily available on the Internet. I find it fascinating and of sufficient public interest to reproduce it here in full. I have not altered a thing in the following text, except putting it in italics and putting the section where the BCA quote our text in bold for clarity.
CONFIDENTIAL FOR BCA MEMBERS ONLY
Information for BCA members regarding an article in the Daily Mail – April 8th 2008
A double page spread appeared in the edition of the Daily Mail April 8th 2008 on page 46 and 47 and titled ‘Alternative Medicine The Verdict’.
The article was written by Simon Singh and Edzard Ernst and is a publicity prelude to a book they have written called ‘Trick or Treatment? Alternative Medicine on Trial’, which will be published later this month.
The article covers Alexander Technique, Aromatherapy, Flower Remedy, Chiropractic, Hypnotherapy, Magnet Therapy and Osteopathy.
The coverage of Chiropractic follows a familiar pattern for E Ernst. The treatment is oversimplified in explanation, with a heavy emphasis on words like thrust, strong and aggressive. There is tacit acknowledgement that chiropractic works for back pain, but then there is a long section about caution regarding neck manipulation. The article concludes by advising people not to have their neck manipulated and not to allow children to be treated.
WHAT IS IT? Chiropractors use spinal manipulation to realign the spine to restore mobility. Initial examination often includes X-ray images or MRI scans.
Spinal manipulation can be a fairly aggressive technique, which pushes the spinal joint slightly beyond what it is ordinarily capable of achieving, using a technique called high-velocity, low-amplitude thrust – exerting a relatively strong force in order to move the joint at speed, but the extent of the motion needs to be limited to prevent damage to the joint and its surrounding structures.
Although spinal manipulation is often associated with a cracking sound, this is not a result of the bones crunching or a sign that bones are being put back; the noise is caused by the release and popping of gas bubbles, generated when the fluid in the joint space is put under severe stress.
Some chiropractors claim to treat everything from digestive disorders to ear infections, others will treat only back problems.
DOES IT WORK? There is no evidence to suggest that spinal manipulation is effective for anything but back pain and even then conventional approaches (such as regular exercise and ibuprofen) are just as likely to be effective and are cheaper.
Neck manipulation has been linked to neurological complications such as strokes – in 1998, a 20-year-old Canadian woman died after neck manipulation caused a blood clot which led to stroke. We would strongly recommend physiotherapy exercises and osteopathy ahead of chiropractic therapy because they are at least effective and much safer.
If you do decide to visit a chiropractor despite our concerns and warnings, we very strongly recommend you confirm your chiropractor won’t manipulate your neck. The dangers of chiropractic therapy to children are particularly worrying because a chiropractor would be manipulating an immature spine.

As we are aware that patients or potential patients of our members will be confronted with questions regarding this article, we have put together some comment and Q&As to assist you.
• Please consider this information as strictly confidential and for your use only.
• Only use this if a patient asks about these specific issues; there is nothing to be gained from releasing any information not asked for.
• Do not duplicate these patient notes and hand out direct to the patient or the media; these are designed for you to use when in direct conversation with a patient.
The BCA will be very carefully considering any questions or approaches we may receive from the press and will respond to them using specially briefed spokespeople. We would strongly advise our members not to speak directly to the press on any of the issues raised as a result of this coverage.
Please note that In the event of you receiving queries from the media, please refer these direct to BCA (0118 950 5950 – Anne Barlow or Sue Wakefield) or Publicasity (0207 632 2400 – Julie Doyle or Sara Bailey).
The following points should assist you in answering questions that patients may ask with regard to the safety and effectiveness of chiropractic care. Potential questions are detailed along with the desired ‘BCA response’:
o “The Daily Mail article seems to suggest chiropractic treatment is not that effective”
Nothing could be further from the truth. The authors have had to concede that chiropractic treatment works for back pain as there is overwhelming evidence to support this. The authors also contest that pain killers and exercises can do the job just as well. What they fail to mention is that research has shown that this might be the case for some patients, but the amount of time it may take to recover is a lot longer and the chance of re-occurrence of the problem is higher. This means that chiropractic treatment works, gets results more quickly and helps prevent re-occurrence of the problem. Chiropractic is the third largest healthcare profession in the world and in the UK is recognised and regulated by the UK Government.
o “The treatment is described as aggressive, can you explain?”
It is important to say that the authors of the article clearly have no direct experience of chiropractic treatment, nor have they bothered to properly research the training and techniques. Chiropractic treatment can take many forms, depending on the nature of the problem, the particular patient’s age and medical history and other factors. The training chiropractors receive is overseen by the government appointed regulator and the content of training is absolutely designed to ensure that an individual chiropractor understands exactly which treatment types are required in each individual patient scenario. Gentle technique, massage and exercise are just some of the techniques available in the chiropractor’s ‘toolkit’. It is a gross generalisation and a demonstration of lack of knowledge of chiropractic to characterise it the way it appeared in the article.
o “The article talked about ‘claims’ of success with other problems”
There is a large and undeniable body of evidence regarding the effectiveness of chiropractic treatment for musculoskeletal problems such as back pain. There is also growing evidence that chiropractic treatment can help many patients with other problems; persistent headaches for example. There is also anecdotal evidence and positive patient experience to show that other kinds of problems have been helped by chiropractic treatment. For many of these kinds of problems, the formal research is just beginning and a chiropractor would never propose their treatment as a substitute for other, ongoing treatments.
o “Am I at risk of having a stroke if I have a chiropractic treatment?”
What is important to understand is that any association between neck manipulation and stroke is extremely rare. Chiropractic is a very safe form of treatment.
Another important point to understand is that the treatments employed by chiropractors are statistically safer than many other conservative treatment options (such as ibuprofen and other pain killers with side effects such as gastric bleeding) for mechanical low back or neck pain conditions.
A research study in the UK, published just last year studied the neck manipulations received by nearly 20,000 chiropractic patients. NO SERIOUS ADVERSE SIDE EFFECTS WERE IDENTIFIED AT ALL. In another piece of research, published in February this year, stroke was found to be a very rare event and the risk associated with a visit to a chiropractor appeared to be no different from the risk of a stroke following a visit to a GP.
Other recent research shows that such an association with stroke may occur once in every 5.85 million adjustments.
To put this in context, a ‘significant risk’ for any therapeutic intervention (such as pain medication) is defined as 1 in 10,000.
Additional info: Stroke is a natural occurring phenomenon, and evidence dictates that a number of key risk factors increase the likelihood of an individual suffering a stroke. Smoking, high blood pressure, high cholesterol and family medical histories can all contribute; rarely does a stroke occur in isolation from these factors. Also, stroke symptoms can be similar to that of upper neck pains, stiffness or headaches, conditions for which patients may seek chiropractic treatment. BCA chiropractors are trained to recognise and diagnose these symptoms and advise appropriate mainstream medical care.
o “Can you tell if I am at risk from stroke?”
As a BCA chiropractor I am trained to identify risk factors and would not proceed with treatment if there was any doubt as to the patient’s suitability. Potential risks may come to light during the taking of a case history, which may include: smoking, high cholesterol, contraceptive pill, Blood clotting problems/blood thinning meds, heart problems, trauma to the head etc and on physical examination e.g. high blood pressure, severe osteoarthritis of the neck, history of rheumatoid arthritis
o “Do you ever tell patients if they are at risk?”
Yes, I would always discuss risks with patients and treatment will not proceed without informed consent.
o “Is it safe for my child to be treated by a chiropractor”
It is a shame that the article so generalises the treatment provided by a chiropractor, that it makes such outrageous claims. My training in anatomy, physiology and diagnosis means that I absolutely understand the demands and needs of spines from the newborn baby to the very elderly patient. The techniques and treatments I might use on a 25 year old are not the same as those I would employ on a 5 year old. I see a lot of children as patients at this clinic and am able to offer help with a variety of problems with the back, joints and muscles. I examine every patient very thoroughly, understand their medical history and discuss my findings with them and their parents before undertaking any treatment.
– Chiropractic is a mature profession and numerous studies clearly demonstrate that chiropractic treatment, including manipulative and spinal adjustment, is both safe and effective.
– Thousands of patients are treated by me and my fellow chiropractors every day in the UK. Chiropractic is a healthcare profession that is growing purely because our patients see the results and GPs refer patients to us because they know we get results!
This article is to promote a book and a controversial one at that. Certainly, in the case of the comments about chiropractic, there is much evidence and research that has formed part of guidelines developed by the Royal Society of General Practitioners, NICE and other NHS/Government agencies, has been conveniently ignored. The statements about chiropractic treatment and technique demonstrate that there has clearly been no research into the actual education that chiropractors in the UK receive – in my case a four year full-time degree course that meets stringent educational standards set down by the government appointed regulator.
Shortly after the article in The Daily Mail, our book was published and turned out to be much appreciated by critical thinkers across the globe — not, however, by chiropractors.
At the time, I did, of course, not know about the above “strictly confidential” message to BCA members, yet I strongly suspected that chiropractors would do everything in their power to dispute our central argument, namely that most of the therapeutic claims by chiropractors were not supported by sufficient evidence. I also knew that our evidence for it was rock solid; after all, I had researched the evidence for or against chiropractic in full depth and minute detail and published dozens of articles on the subject in the medical literature.
When, one and a half weeks after our piece in the Mail, Simon published his now famous Guardian comment stating that the BCA “happily promote bogus treatments”, he was sued for libel by the BCA. I think the above “strictly confidential” message already reveals the BCA’s determination and their conviction to be on firm ground. As it turned out, they were wrong. Not only did they lose their libel suit, but they also dragged chiropractic into a deep crisis.
The “strictly confidential” message is intriguing in several more ways – I will leave it to my readers to pick out some of the many gems hidden in this text. Personally, I find the most remarkable aspect that the BCA seems to attempt to silence its own members regarding the controversy about the value of their treatments. Instead they proscribe answers (should I say doctrines?) of highly debatable accuracy for them, almost as though chiropractors were unable to speak for themselves. To me, this smells of cult-like behaviour, and is by no means indicative of a mature profession – despite their affirmations to the contrary.
