Getting good and experienced lecturers for courses is not easy. Having someone who has done more research than most working in the field and who is internationally known, might therefore be a thrill for students and an image-boosting experience of colleges. In the true Christmas spirit, I am today making the offer of being of assistance to the many struggling educational institutions of alternative medicine .
A few days ago, I tweeted about my willingness to give free lectures to homeopathic colleges (so far without response). Having thought about it a bit, I would now like to extend this offer. I would be happy to give a free lecture to the students of any educational institution of alternative medicine. I suggest to
- do a general lecture on the clinical evidence of the 4 major types of alternative medicine (acupuncture, chiropractic, herbal medicine, homeopathy) or
- give a more specific lecture with in-depth analyses of any given alternative therapy.
I imagine that most of the institutions in question might be a bit anxious about such an idea, but there is no need to worry: I guarantee that everything I say will be strictly and transparently evidence-based. I will disclose my sources and am willing to make my presentation available to students so that they can read up the finer details about the evidence later at home. In other words, I will do my very best to only transmit the truth about the subject at hand.
Nobody wants to hire a lecturer without having at least a rough outline of what he will be talking about – fair enough! Here I present a short summary of the lecture as I envisage it:
- I will start by providing a background about myself, my qualifications and my experience in researching and lecturing on the matter at hand.
- This will be followed by a background on the therapies in question, their history, current use etc.
- Next I would elaborate on the main assumptions of the therapies in question and on their biological plausibility.
- This will be followed by a review of the claims made for the therapies in question.
- The main section of my lecture would be to review the clinical evidence regarding the efficacy of therapies in question. In doing this, I will not cherry-pick my evidence but rely, whenever possible, on authoritative systematic reviews, preferably those from the Cochrane Collaboration.
- This, of course, needs to be supplemented by a review of safety issues.
- If wanted, I could also say a few words about the importance of the placebo effect.
- I also suggest to discuss some of the most pertinent ethical issues.
- Finally, I would hope to arrive at a few clear conclusions.
You see, all is entirely up to scratch!
Perhaps you have some doubts about my abilities to lecture? I can assure you, I have done this sort of thing all my life, I have been a professor at three different universities, and I will probably manage a lecture to your students.
A final issue might be the costs involved. As I said, I would charge neither for the preparation (this can take several days depending on the exact topic), nor for the lecture itself. All I would hope for is that you refund my travel (and, if necessary over-night) expenses. And please note: this is time-limited: approaches will be accepted until 1 January 2015 for lectures any time during 2015.
I can assure you, this is a generous offer that you ought to consider seriously – unless, of course, you do not want your students to learn the truth!
(In which case, one would need to wonder why not)
A German homeopathic journal, Zeitschrift Homoeopathie, has just published the following interesting article entitled HOMEOPATHIC DOCTORS HELP IN LIBERIA. It provides details about the international team of homeopaths that travelled to Liberia to cure Ebola. Here I take the liberty of translating it from German into English. As most of it is fairly self-explanatory, I abstain from any comments of my own – however, I am sure that my readers will want to add their views.
In mid-October, an international team of 4 doctors travelled to the West African country for three weeks. The mission in a hospital in Ganta, a town with about 40 000 inhabitants on the border to Guinea, ended as planned on 7 November. The exercise was organised by the World Association of Homeopathic Doctors, the Liga Medicorum Homoeopathica Internationalis (LMHI), with support of by the German Central Association of Homeopathic Doctors. The aim was to support the local doctors in the care of the population and, if possible, also to help in the fight against the Ebola epidemic. The costs for the three weeks’ stay were financed mostly through donations from homeopathic doctors.
“We know that we were invited mainly as well-trained doctors to Liberia, and that or experience in homeopathy was asked for only as a secondary issue”, stresses Cornelia Bajic, first chairperson of the DZVhA (German Central Association of Homeopathic Doctors). The doctors from India, USA, Switzerland and Germany were able to employ their expertise in several wards of the hospital, to help patients, and to support their Liberian colleagues. It was planned to use and document the homeopathic treatment of Ebola-patients as an adjunct to the WHO prescribed standard treatment. “Our experience from the treatment of other epidemics in the history of medicine allows the conclusion that a homeopathic treatment might significantly reduce the mortality of Ebola patients”, judges Bajic. The successful use of homeopathic remedies has been documented for example in Cholera, Diphtheria or Yellow Fever.
In Ganta, the doctors of the LMHI team treated patients with “at times most serious diseases, particularly inflammatory conditions, children with Typhus, meningitis, pneumonias, and unclear fevers – each time only under the supervision of the local doctor in charge”, reports Dr Ortrud Lindemann, who also worked obstetrically in Ganta. The medical specialist reports after her return: “When we had been 10 days in the hospital, the successes had become known, and the patients stood in queues to get treated by us.” The homeopathic doctors received thanks from the Ganta hospital for their work, it was said that it had been helpful for the patients and a blessing for the employees of the hospital.
POLITICAL CONSIDERATIONS MORE IMPORTANT THAN MEDICAL TREATMENT?
This first LMHI team of doctors was forbidden to care for patients from the “Ebola Treatment Unit”. The decision was based on an order of the WHO. A team of Cuban doctors was also waiting in vain for being allowed to work. “We are dealing here with a dangerous epidemic and a large number of seriously ill patients. And despite a striking lack of doctors in West Africa political considerations are more important than the treatment of these patients”, criticises the DZVhA chairperson Bajic. Now a second team is to travel to Ganta to support the local doctors.
Acupuncture seems to be as popular as never before – many conventional pain clinics now employ acupuncturists, for instance. It is probably true to say that acupuncture is one of the best-known types of all alternative therapies. Yet, experts are still divided in their views about this treatment – some proclaim that acupuncture is the best thing since sliced bread, while others insist that it is no more than a theatrical placebo. Consumers, I imagine, are often left helpless in the middle of these debates. Here are 7 important bits of factual information that might help you make up your mind, in case you are tempted to try acupuncture.
- Acupuncture is ancient; some enthusiast thus claim that it has ‘stood the test of time’, i. e. that its long history proves its efficacy and safety beyond reasonable doubt and certainly more conclusively than any scientific test. Whenever you hear such arguments, remind yourself that the ‘argumentum ad traditionem’ is nothing but a classic fallacy. A long history of usage proves very little – think of how long blood letting was used, even though it killed millions.
- We often think of acupuncture as being one single treatment, but there are many different forms of this therapy. According to believers in acupuncture, acupuncture points can be stimulated not just by inserting needles (the most common way) but also with heat, electrical currents, ultrasound, pressure, etc. Then there is body acupuncture, ear acupuncture and even tongue acupuncture. Finally, some clinicians employ the traditional Chinese approach based on the assumption that two life forces are out of balance and need to be re-balanced, while so-called ‘Western’ acupuncturists adhere to the concepts of conventional medicine and claim that acupuncture works via scientifically explainable mechanisms that are unrelated to ancient Chinese philosophies.
- Traditional Chinese acupuncturists have not normally studied medicine and base their practice on the Taoist philosophy of the balance between yin and yang which has no basis in science. This explains why acupuncture is seen by traditional acupuncturists as a ‘cure all’ . In contrast, medical acupuncturists tend to cite neurophysiological explanations as to how acupuncture might work. However, it is important to note that, even though they may appear plausible, these explanations are currently just theories and constitute no proof for the validity of acupuncture as a medical intervention.
- The therapeutic claims made for acupuncture are legion. According to the traditional view, acupuncture is useful for virtually every condition affecting mankind; according to the more modern view, it is effective for a relatively small range of conditions only. On closer examination, the vast majority of these claims can be disclosed to be based on either no or very flimsy evidence. Once we examine the data from reliable clinical trials (today several thousand studies of acupuncture are available – see below), we realise that acupuncture is associated with a powerful placebo effect, and that it works better than a placebo only for very few (some say for no) conditions.
- The interpretation of the trial evidence is far from straight forward: most of the clinical trials of acupuncture originate from China, and several investigations have shown that very close to 100% of them are positive. This means that the results of these studies have to be taken with more than a small pinch of salt. In order to control for patient-expectations, clinical trials can be done with sham needles which do not penetrate the skin but collapse like miniature stage-daggers. This method does, however, not control for acupuncturists’ expectations; blinding of the therapists is difficult and therefore truly double (patient and therapist)-blind trials of acupuncture do hardly exist. This means that even the most rigorous studies of acupuncture are usually burdened with residual bias.
- Few acupuncturists warn their patients of possible adverse effects; this may be because the side-effects of acupuncture (they occur in about 10% of all patients) are mostly mild. However, it is important to know that very serious complications of acupuncture are on record as well: acupuncture needles can injure vital organs like the lungs or the heart, and they can introduce infections into the body, e. g. hepatitis. About 100 fatalities after acupuncture have been reported in the medical literature – a figure which, due to lack of a monitoring system, may disclose just the tip of an iceberg.
- Given that, for the vast majority of conditions, there is no good evidence that acupuncture works beyond a placebo response, and that acupuncture is associated with finite risks, it seems to follow that, in most situations, the risk/benefit balance for acupuncture fails to be convincingly positive.
Here I am not writing about herbal medicine in general – parts of which are supported by some encouraging evidence (I will therefore post more than one ‘seven things to remember…’ article on this subject) – here I am writing about the risks and benefits of consulting a traditional herbal practitioner. Herbalists come in numerous guises depending what tradition they belong to: Chinese herbalist, traditional European herbalist, Ayurvedic practitioner, Kampo practitioner etc. If you consult such a therapist, you should be aware of the following issues.
- Worldwide, the treatment by traditional herbal practitioners is by far the most common form of herbal medicine; it is more common than to use specific, well-tested herbs to treat specific conventionally diagnosed conditions (an approach that might best be called ‘rational phytotherapy’).
- Herbalists often use their very own diagnostic methods (think, for instance, of ‘tongue and pulse diagnoses’ used by Chinese herbalists) and reject (or are untrained to use) conventional diagnostic methods. The traditional diagnostic techniques of herbalists have either not been validated at all or they have been tested and found to be not valid.
- Herbalists usually do not recognise conventional disease categories. Instead they arrive at a diagnosis according to their specific philosophy which has no grounding in reality (for instance, energy imbalance in traditional Chinese herbalism).
- Herbalists individualise their treatments, meaning that 10 patients suffering from depression, for instance, might receive 10 different, tailor-made prescriptions according to their individual characteristics (and none of the 10 patients might receive St John’s Wort, the only herbal remedy that actually is proven to work for depression).
- Typically, such prescriptions contain not one herbal ingredient, but are mixtures of many – up to 10 or 20 – herbs or herbal extracts.
- Even though the efficacy of the individualised herbal approach can, of course, be tested in rigorous trials, and even though about a dozen such studies are available today, there is currently no good evidence to show that it is effective.
- The risk of harm through these individualised herbal mixtures can be considerable: the more ingredients, the higher the likelihood that one of them has toxic effects or that one interacts with a prescription medicine. Essentially, this means that there is no good evidence that individualised herbal treatments as used by so many herbal practitioners across the globe generates more good than harm.
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.
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.
Whenever I give a public lecture about homeopathy, I explain what it is, briefly go in to its history, explain what its assumptions are, and what the evidence tells us about its efficacy and safety. When I am finished, there usually is a discussion with the audience. This is the part I like best; in fact, it is the main reason why I made the effort to do the lecture in the first place.
The questions vary, of course, but you can bet your last shirt that someone asks: “We know it works for animals; animals cannot experience a placebo-response, and therefore your claim that homeopathy relies on nothing but the placebo-effect must be wrong!” At this stage I often despair a little, I must admit. Not because the question is too daft, but because I did address it during my lecture. Thus I feel that I have failed to get the right message across – I despair with my obviously poor skills of giving an informative lecture!
Yet I need to answer the above question, of course. So I reiterate that the perceived effectiveness of homeopathy relies not just on the placebo-effect but also on phenomena such as regression towards the mean, natural history of the condition etc. I also usually mention that it is erroneous to assume that animals cannot benefit from placebo-effects; they can be conditioned, and pets can react to the expectations of their owners.
Finally, I need to mention the veterinary clinical evidence which – just like in the case of human patients – fails to show that homeopathic remedies are better than placebos for treating animals. Until recently, this was not an easy task because no systematic review of randomised placebo-controlled trials (RCTs) of veterinary homeopathy was available. Now, I am happy to announce, this situation has changed.
Using Cochrane methods, a brand-new review aimed to assess risk of bias and to quantify the effect size of homeopathic interventions compared with placebo for each eligible peer-reviewed trial. Judgement in 7 assessment domains enabled a trial’s risk of bias to be designated as low, unclear or high. A trial was judged to comprise reliable evidence, if its risk of bias was low or was unclear in specified domains. A trial was considered to be free of vested interest, if it was not funded by a homeopathic pharmacy.
The 18 RCTs found by the researchers were disparate in nature, representing 4 species and 11 different medical conditions. Reliable evidence, free from vested interest, was identified in only two trials:
- homeopathic Coli had a prophylactic effect on porcine diarrhoea (odds ratio 3.89, 95 per cent confidence interval [CI], 1.19 to 12.68, P=0.02);
- individualised homeopathic treatment did not have a more beneficial effect on bovine mastitis than placebo intervention (standardised mean difference -0.31, 95 per cent CI, -0.97 to 0.34, P=0.35).
The authors conclusions are clear: Mixed findings from the only two placebo-controlled RCTs that had suitably reliable evidence precluded generalisable conclusions about the efficacy of any particular homeopathic medicine or the impact of individualised homeopathic intervention on any given medical condition in animals.
My task when lecturing about homeopathy has thus become a great deal easier. But homeopathy-fans are not best pleased with this new article, I guess. They will try to claim that it was a biased piece of research conducted, most likely, by notorious anti-homeopaths who cannot be trusted. So who are the authors of this new publication?
They are RT Mathie from the British Homeopathic Association and J Clausen from one of Germany’s most pro-homeopathic institution, the ‘Karl und Veronica Carstens-Stiftung’.
DOES ANYONE BELIEVE THAT THIS ARTICLE IS BIASED AGAINST HOMEOPATHY?
Hard to believe that it’s been already two years! On 14 October 2012, I posted the very first article. It set out what I wanted to achieve:
Why another blog offering critical analyses of the weird and wonderful stuff that is going on in the world of alternative medicine? The answer is simple: compared to the plethora of uncritical misinformation on this topic, the few blogs that do try to convey more reflected, sceptical views are much needed; and the more we have of them, the better.
At the time, I had no idea how successful this venture into the unknown would become. Today, over 350 articles have been posted and almost 8000 comments have contributed to an often lively debate about almost all aspects of alternative medicine. Currently, the blog has well over 1000 – 2000 visitors every day. Selected posts have been translated and re-published in about half a dozen languages. I admit: I am quite proud of all that!
Back in 2012, I also had no idea how much fun I would derive from doing all this. Those who know me well would probably confirm that I am an unlikely candidate for getting his teeth into something like a blog. Thanks to mostly helpful and often brilliant comments from my readers, this blog has become a constant source of entertainment and information for me and, I hope, many others too.
My aims have remained very much the same during these last two years. Today I might formulate them as follows:
- I want to inform the public about all matters related to alternative medicine.
- I aim to review new evidence as it emerges.
- I also wish to entertain my readers.
- I feel a strong need to create a counter-balance to the thousands of blogs that are dangerously promotional and woefully uncritical.
- And I want to help consumers to become much more effective ‘BULL-SHIT DETECTORS’ (I got this term recently from Sir Iain Chalmers).
Of course, none of these aims are achievable without active, critical, witty and outspoken readers and commentators. I would like to take the occasion of this second anniversary to thank everybody who has helped with and contributed to this blog. May the good work and intense fun continue!
Reflexology? Isn’t that an alternative therapy? And as such, a physiotherapist would not normally use it, most of us might think.
Well, think again! Here is what the UK Chartered Society of Physiotherapists writes about reflexology:
Developed centuries ago in countries such as China, Egypt and India, reflexology is often referred to as a ‘gentle’ and ‘holistic’ therapy that benefits both mind and body. It centres on the feet because these are said by practitioners to be a mirror, or topographical map, for the rest of the body. Manipulation of certain pressure, or reflex, points is claimed to have an effect on corresponding zones in the body. The impact, say reflexologists, extends throughout – to bones, muscles, organs, glands, circulatory and neural pathways. The head and hands can also be massaged in some cases. The treatment is perhaps best known for use in connection with relaxation and relief from stress, anxiety, pain, sleep disorders, headaches, migraine, menstrual and digestive problems. But advocates say it can be used to great effect far more widely, often in conjunction with other treatments.
Reflexology, or Reflex Therapy (RT) as some physiotherapists prefer to call it, clearly is approved by the UK Chartered Society of Physiotherapists. And what evidence do they have for it?
One hundred members of the Association of Chartered Physiotherapists in Reflex Therapy (ACPIRT) participated in an audit to establish a baseline of practice. Findings indicate that experienced therapists use RT in conjunction with their professional skills to induce relaxation (95%) and reduce pain (86%) for patients with conditions including whiplash injury and chronic pain. According to 68% of respondents, RT is “very good,” “good” or “as good as” orthodox physiotherapy practices. Requiring minimal equipment, RT may be as cost effective as orthodox physiotherapy with regards to duration and frequency of treatment.
But that’s not evidence!!! I hear you grumble. No, it isn’t, I agree.
Is there good evidence to show that RT is effective?
I am afraid not!
My own systematic review concluded that the best evidence available to date does not demonstrate convincingly that reflexology is an effective treatment for any medical condition.
Does that mean that the Chartered Society of Physiotherapists promotes quackery?
I let my readers answer that question.
What on earth is that?
Whatever it is, it is big; there are more than half a million websites on it, and it seems to me that a lot of dosh is being made with pranic healing.
But what is it?
This website might be as good as any to explain:
Pranic Healing is a form of ancient energy medicine, which utilizes the inherent energy Prana (life force or energy) to balance, and promote the body’s energy and its processes. Prana is a Sanskrit word which actually means, the vital force that keeps us alive and healthy. Pranic healing is a holistic approach as it assumes a person in its complexity and does not separate the body and the mind.
It was developed by Grand Master ChoaKok Sui who founded the World Pranic Healing Foundation. He is a Manila-based businessman of Chinese origin – a spiritual teacher, writer and therapist of Pranic healing system.
According to ancient medicine, the body is composed of several physical elements including skin, bones, muscles, organs and so on which function with the help of Prana.The pranais present in the form of +ve and –ve ions. Pranic therapy or treatment involves the act of manipulating the energy (by experts) to restore the energy of the chakras in the body which is believed to treat the condition. Although it’s difficult to detect and measure life energy, its existence is undoubtedly proved…
Following health issues can be successfully treated with Pranic healing: Sleeping illness (lack of sleep) Mental illnesses including depression, anxiety etc. Stress Sprains and strains Body aches like neck pain, muscle pain, back pain etc. A recent trauma and related inflammation Improve psycho-physical aspects in athletes Improve memory Enhance energy level Treat headache Fight ulcers (intestinal) Heal respiratory illnesses, including sinusitis and asthma Skin diseases, including eczema Improves overall immunity Treat the various causes of infertility Aesthetic treatments such as Pranic face lift, bust lift, hip and tummy tuck etc.
Not only is pranic healing a true panacea, it also includes all the buzz-words any self-respecting charlatan wants to employ these days:
- energy medicine
- ancient wisdom
- life force
But the real beauty is, I think, that the existence of the energy – and by implication pranic healing – is undoubtedly proven!
Should we believe this statement?
Not without some evidence, I suggest.
Medline lists all of 4 articles on the subject of pranic healing – not too difficult a task to summarise them quickly here:
The first paper is entirely evidence-free, but we learn the following interesting thing: “When Pranic healing is applied the molecular structure of liquid and dense states of matter can be altered significantly to create positive outcomes, as revealed through research.”
The second article is not actually on pranic healing and contains no relevant information on it.
The third article is merely a promotional essay for nurses that fails to include anything resembling evidence.
The fourth paper finally is much of the same again.
So where is all this science supporting pranic healing? After all any treatment that can alter the molecular structure of matter must amount to a bit of a scientific sensation! Has the evidence perhaps been published in journals that are not Medline-listed? That I find difficult to imagine after realising that even the AUSTRALIAN JOURNAL OF HOLISTIC NURSING (one of the above 4 publications) is included in this database. And, in any case, such a scientific sensation deserves to be published in one of the leading science-journals!
Could it be that there is not science to pranic healing at all?
Could the whole thing be a hoax?
I sure hope one of my readers can point me to the science thus proving my suspicion to be unfounded!
