No, this post is not about the pop duo ‘EURYTHMICS’, it is about ‘EURYTHMY’ which pre-dates the pop duo by a few decades.

Eurythmy is a movement therapy of anthroposophic medicine which, according to its proponents, has positive effects on a person’s physical body, spirit, and soul. It is involves expressive movements developed by Rudolf Steiner in conjunction with Marie von Sivers in the early 20th century. It is used as a performance art, in education, especially in Steiner schools, and – as part of anthroposophic medicine – for therapeutic purposes. Here is what one pro-eurymthy website tells us about it:

Eurythmy is one of Rudolf Steiner’s proudest achievements. To better understand what Steiner says about eurythmy, you should read his self-titled “A Lecture on Eurythmy” Not always one to boast, Steiner says:

EURYTHMY has grown up out of the soil of the Anthroposophical Movement, and the history of its origin makes it almost appear to be a gift of the forces of destiny.

Steiner, Rudolf. A Lecture on Eurythmy, 1923

Clearly, Steiner felt that eurythmy was something very special, and of great importance. As such, eurythmy is a tool of Anthroposophy used to reveal and bring about a certain “spiritual impulse” in our age:

For it is the task of the Anthroposophical Movement to reveal to our present age that spiritual impulse which is suited to it.I speak in all humility when I say that within the Anthroposophical Movement there is a firm conviction that a spiritual impulse of this kind must now, at the present time, enter once more into human evolution. And this spiritual impulse must perforce, among its other means of expression, embody itself in a new form of art. It will increasingly be realised that this particular form of art has been given to the world in Eurythmy.

Steiner, Rudolf. A Lecture on Eurythmy

 

The question is, of course,  whether as a therapy eurythmy works. A recent publication might give an answer.

The aim of this systematic review was to update and summarize the relevant literature on the effectiveness of eurythmy in a therapeutic context since 2008. It is thus an up-date of a previously published review. This paper  found 8 citations which met the inclusion criterion: 4 publications referring to a prospective cohort study without control group (the AMOS study), and 4 articles referring to 2 explorative pre-post studies without control group, 1 prospective, non-randomized comparative study, and 1 descriptive study with a control group. The methodological quality of studies ranged in from poor to good, and in sample size from 5 to 898 patients. In most studies, EYT was used as an add-on, not as a mono-therapy. The studies described positive treatment effects with clinically relevant effect sizes in most cases.

For the up-date, different databases like PubMed, MEDPILOT, Research Gate, The Cochrane Library, DIMDI, Arthe and also the journal databases Der Merkurstab and the European Journal of Integrative Medicine were searched for prospective and retrospective clinical trials in German or English language. There were no limitations for indication, considered outcome or age of participants. Studies were evaluated with regard to their description of the assembly process and treatment, adequate reporting of follow-ups, and equality of comparison groups in controlled trials.

Eleven studies met the inclusion criteria. These included two single-arm, non-controlled pilot studies, two publications on the same non-randomized controlled trial and one case study; six further studies referred to a prospective cohort study, the Anthroposophic Medicine Outcome Study. Most of these studies described positives treatment effects with varying effect sizes. The studies were heterogynous according to the indications, age groups, study design and measured outcome. The methodological quality of the studies varied considerably.

The authors who all come from the Institute of Integrative Medicine, anthroposophical University of Witten/Herdecke in Germany draw the following conclusions: Eurythmy seems to be a beneficial add-on in a therapeutic context that can improve the health conditions of affected persons. More methodologically sound studies are needed to substantiate this positive impression.

I am puzzled! How on earth could they reach this conclusion? There is not a single trial that would  allow to establish cause and effect!!! The way I read the evidence from the therapeutic trials included in this and the previous reviews, the only possible conclusion is that EURYTHMY IS A WEIRD THERAPY FOR WHICH THERE IS NOT GOOD EVIDENCE WHATSOEVER.

Medical ethics comprise a set of rules and principles which are essential for all aspects of medicine, including of course research. The main issues are:

  • Respect for autonomy – patients must have the right to refuse or choose their treatments.
  • Beneficence – researchers and clinicians must act in the best interest of the patient.
  • Non-maleficence – the expected benefits of interventions must outweigh their risks.
  • Justice – the distribution of health resources must be fair.
  • Respect for persons – patients must be treated with dignity.
  • Truthfulness and honesty – informed consent is an essential element in research and clinical practice.

While all of this has long been fairly standard in conventional health care, it is often neglected in alternative medicine. It is therefore timely to ask, how much of research in the realm of alternative medicine abides by the rules of medical ethics?

After more than two decades of involvement in this sector, I have serious and growing concerns. The subject is, of course complex, but the way I see it, in alternative medicine there are two main areas where medical ethics are violated with some regularity.

  1. Nonsensical research projects
  2. Lack of informed consent

NONSENSICAL RESEARCH PROJECTS

At best, nonsensical research is a waste of precious resources, at worst it violates the beneficence principle. In alternative medicine, nonsensical research seems to happen ad nauseam. Regular readers of this blog will have seen plenty of examples of such abuse – for instance, if researchers conduct a clinical trial of chiropractic spinal manipulation for improving the singing voices of choir singers, or homeopaths test whether their remedies enhance female fertility. Often, nonsensical research happens when naïve enthusiasts decide to dabble a bit in science in order to promote their trade – but without realising that research would require a minimum of education.

But there are other occasions when it seems that the investigators know only too well what they are doing. Take for instance the plethora of ‘pragmatic’ trials which are currently so much ‘en vogue’ in alternative medicine. They can be designed in such a way that their results must produce what the researchers intended to show; the ‘A+B versus B’ study design is a prominent and obvious example of this type of abuse which I have repeatedly written about on this blog.

I use the term ‘abuse’ intentionally, because that is precisely what it is, in my view. Nonsensical research abuses the willingness of patients to participate by misleading them that it is a worthwhile sacrifice. In reality it is an unethical attempt to generate findings that can mislead us all. Moreover, it gives science a bad name and can lead to patients’ unwillingness to take part in research that does need doing. The damage done by nonsensical research projects is therefore immeasurable.

INFORMED CONSENT

Informed consent is essential in research for protecting the interests of the volunteering patients. When a clinical trial is first conceived, the researchers need to work out all the details, write a protocol and submit it to their ethics committee. Their submission has to give evidence that all the participating patients have given informed consent in writing before they are enrolled into the study. That means, they have to be told the essential details about what might happen to them during the trial.

In a placebo-controlled trial of homeopathy, for instance, they might be told that they will receive either a homeopathic remedy or a placebo during the study period. They might also be informed that there is some encouraging evidence that the former works, and that the trial is designed to define to what extend this is so. Generating this knowledge, they might further be told, will help future patients and will be an important contribution to improving health care. Based on such phraseology, the ethics committee is likely to allow the study to go ahead, and patients are likely to agree to take part.

But, of course, this information is less than truthful. An honest and full information for patients would need to include the following points:

  • you will receive either a homeopathic remedy or a placebo,
  • the former contains no active molecules and the totality of the most reliable evidence does not show that it works for your condition,
  • this means that you will receive either a homeopathic or a conventional placebo,
  • neither of these can possibly help your condition,
  • the study can therefore not advance our knowledge in any way,
  • during the trial your condition will remain untreated which is likely to increase your suffering unnecessarily.

If any research team would truthfully disclose this information, no ethics committee would pass their protocol. If by some weird mistake they did, no patients would volunteer to participate in the study.

I have chosen here the example of homeopathy (because most readers will understand it quite easily), but I could have used almost any other alternative treatment. The issues are identical or very similar: informed consent is usually misinformed consent. If it were fully and truthfully informed, it would neither pass the hurdle of the essential ethics approval nor would it lend itself to recruiting sufficiently large numbers of patients.

CONCLUSION

There are, I think, very serious concerns about the ethical standards in alternative medicine research. I have been banging on about these issues since many years (for instance here and here and here and here). Predictably, this did not find much resonance in the realm of alternative medicine. Regrettably, very few ethicists have so far taken this subject seriously; they seem to feel that these problems are trivial compared to the important issues medical ethics face in conventional health care. I remain unconvinced that this is true and believe it is high time to systematically address the ethics of alternative medicine.

Conventional cough syrups do not have the best of reputations – but the repute of homeopathic cough syrups is certainly not encouraging. So what should one do with such a preparation? Forget about it? No, one conducts a clinical trial, of course! Not just any old trial but one where science, ethics and common sense are absent. Here are the essentials of a truly innovative study that, I think, has all of these remarkable qualities:

The present prospective observational study investigated children affected by wet acute cough caused by non-complicated URTIs, comparing those who received the homeopathic syrup versus those treated with the homeopathic syrup plus antibiotic. The aims were: 1) to assess whether the addition of antibiotics to a symptomatic treatment had a role in reducing the severity and duration of acute cough in a pediatric population, as well as in improving cough resolution; 2) to verify the safety of the two treatments. Eighty-five children were enrolled in an open study: 46 children received homeopathic syrup alone for 10 days and 39 children received homeopathic syrup for 10 days plus oral antibiotic treatment (amoxicillin/clavulanate, clarithromycin, and erythromycin) for 7 days. To assess cough severity we used a subjective verbal category-descriptive (VCD) scale. Cough VCD score was significantly (P < 0.001) reduced in both groups starting from the second day of treatment (−0.52 ± 0.66 in the homeopathic syrup group and −0.56 ± 0.55 in children receiving homeopathic syrup plus oral antibiotic treatment). No significant differences in cough severity or resolution were found between the two groups of children in any of the 28 days of the study. After the first week (day 8) cough was completely resolved in more than one-half of patients in both groups. Two children (4.3 %) reported adverse effects in the group treated with the homeopathic syrup alone, versus 9 children (23.1 %) in the group treated with the homeopathic syrup plus antibiotics (P = 0.020).

Conclusions

Our data confirm that the homeopathic treatment in question has potential benefits for cough in children as well, and highlight the strong safety profile of this treatment. Additional antibiotic prescription was not associated with a greater cough reduction, and presented more adverse events than the homeopathic syrup alone.

Let us be clear about what has happened here. I think, the events can be summarised as follows:

  • the researchers come across a homeopathic syrup (anyone who understands respiratory problems and/or therapeutics would be more than a little suspicious of this product, but this team is exceptional),
  • they decide to do a trial with it (a decision which would make some ethicists already quite nervous, but the ethics committee is exceptional too),
  • the question raises, what should the researchers give to the control group?
  • someone has the idea, why not compare our dodgy syrup against something that is equally dodgy, perhaps even a bit unsafe?
  • the researchers are impressed and ask: but what precisely could we use?
  • let’s take antibiotics; they are often used for acute coughs, but the best evidence fails to show that they are helpful and they have, of course, risks,
  • another member of the team adds: let’s use children, they and their mothers are unlikely to understand what we are up to,
  • the team is in agreement,
  • Boiron, the world’s largest producer of homeopathic products, accepts to finance the study,
  • a protocol is written,
  • ethics approval is obtained,
  • the trial is conducted and even published by a journal with the help of peer-reviewers who are less than critical.

And the results of the trial? Contrary to the authors’ conclusion copied above, they show that two bogus treatments are worse that one.

BOB’S YOUR UNCLE!

EVERYONE SEEMS HAPPY: THE RESEARCHERS CAN ADD AN ARTICLE TO THEIR PUBLICATION LIST, BOIRON HAS MORE ‘EVIDENCE’ IN FAVOUR OF HOMEOPATHY, AND THE ETHICS COMMITTEE SLEEP JUST AS SOUNDLY AS THE PEER-REVIEWERS.

While my last post was about the risk following some naturopaths’ advice, this one is about the effectiveness of naturopathic treatments. This is a complex subject, not least because naturopaths use a wide range of therapies (as the name implies, they pride themselves of employing all therapeutic means supplied by nature). Some of these interventions are clearly supported by good evidence; for instance, nobody would doubt the effectiveness of a healthy diet or the benefits of regular exercise. But what about all the other treatments naturopaths use? The best approach to find an answer might be to assess not each single therapy but to evaluate the entire package of the naturopathic approach, and not a single study but all such trials.

This is precisely what US researchers have recently done. The purpose of this interesting, new systematic review was to compile and consolidate research that has investigated the whole practice of naturopathic medicine as it is practiced in community settings in order to better assess the quantity and quality of the research, and clinical effect, if any.

In order to get included into the review, studies had to report results from multi-modal treatment delivered by North American naturopathic doctors. The effect size for each study was calculated; no meta-analysis was undertaken.

Fifteen studies met the authors’ inclusion criteria. They covered a wide range of chronic diseases. Most studies had low to medium risks of bias including acknowledged limitations of pragmatic trials. Effect sizes for the primary medical outcomes varied and were statistically significant in 10 out of 13 studies. A quality of life metric was included in all of the RCTs with medium effect size and statistical significance in some subscales.

The authors concluded that previous reports about the lack of evidence or benefit of naturopathic medicine (NM) are inaccurate; a small but compelling body of research exists. Further investigation is warranted into the effectiveness of whole practice NM across a range of health conditions.

This sounds like good news for naturopathy! However, there are several important caveats:

  • the authors seem to have only looked at US studies (naturopathy is a European tradition!),
  • the searches were done three years ago, and more recent data were thus omitted,
  • the authors included all sorts of investigations, even uncontrolled studies; only 6 were RCTs,
  • rigorous trials were very scarce; and for each condition, they were even more so,
  • the authors mention the PRISMA guidelines for systematic reviews implying that they followed them but, in fact, they did not.

My biggest concern, however, is something else. It relates to the interventions tested in these studies. The authors claim that their results table provides full details on this issue but this is unfortunately not true. All we have by way of an explanation is the authors’ remark that the interventions tested in the studies of their review included diet counseling and nutritional recommendations, specific home exercises and physical activity recommendations, deep breathing techniques or other stress reduction strategies, dietary supplements including vitamins, hydrotherapy, soft-tissue manual techniques, electrical muscle stimulation, and botanical medicines.

Survey data from two US states tell us that the most commonly prescribed naturopathic therapeutics are botanical medicines (51% of visits in Connecticut, 43% in Washington), vitamins (41% and 43%), minerals (35% and 39%), homeopathy (29% and 19%) and allergy treatments (11% and 13%). They also inform us that the mean length of a consultation with an US naturopath is about 40 minutes.

I think, this puts things into perspective. If I advise a patient with diabetes or hypertension or coronary heat disease to follow an appropriate diet, exercise and to adhere to some stress reduction program, if in addition I show empathy and compassion during a 40 minute consultation and make sure that my advise is taken seriously and subsequently adhered to, the outcome is likely to be positive. Naturopaths may elect to call this package of intervention ‘naturopathy’, however, I would call it good conventional medicine.

The problem, I think is clear: good therapeutic advice is effective but it is not naturopathy, and it cannot be used to justify the use of doubtful interventions like homeopathy or all sorts of dodgy supplements. Testing whole treatment packages of this nature can therefore lead to highly misleading results, particularly if the researchers draw unwarranted conclusions about specific schools of health care.

Proponents of alternative medicine regularly stress the notion that their treatments are either risk-free or much safer than conventional medicine. This assumption may be excellent for marketing bogus treatments, however, it neglects that even a relatively harmless therapy can become dangerous, if it is ineffective. Here is yet again a tragic reminder of this undeniable fact.

Japanese doctors reported the case of 2-year-old girl who died of precursor B-cell acute lymphoblastic leukaemia (ALL), the most common cancer in children.

She had no remarkable medical history. She was transferred to a hospital because of respiratory distress and died 4 hours after arrival. Two weeks before her death, she had developed a fever of 39 degrees C, which subsided after the administration of a naturopathic herbal remedy. One week before death, she developed jaundice, and her condition worsened on the day of death.

Laboratory test results on admission to hospital showed a markedly elevated white blood cell count. Accordingly, the cause of death was suspected to be acute leukaemia. Forensic autopsy revealed the cause of death to be precursor B-cell ALL.

With the current advancements in medical technology, the 5-year survival rate of children with ALL is nearly 90%. However, in this case, the child’s parents had opted for naturopathy instead of evidence-based medicine. They had not taken her to a hospital for a medical check-up or immunisation since she was an infant. If the child had received routine medical care, she would have a more than 60% chance of being alive 5 years after diagnosis of ALL.

The authors of this case-report concluded that the parents should be accused of medical neglect regardless of their motives.

Such cases are tragic and infuriating in equal measure. There is no way of knowing how often this sort of thing happens; we rely entirely on anecdotes because systematic research is hardly feasible.

While anecdotes of this nature have their obvious limitations, they are nevertheless important. They can serve as poignant reminders that alternative remedies might be relatively harmless, but this does not necessarily apply to all alternative practitioners. Moreover, they should make us redouble our efforts to inform the public responsibly about the all too often trivialized risks of alternative medicine.

When I come across a study with the aim to “examine the effectiveness of acupuncture to relieve symptoms commonly observed in patients in a hospice program” my hopes are high. When I then see that its authors are from the ‘New England School of Acupuncture’, the ‘All Care Hospice and the ‘Tufts University School of Medicine, Boston, my hopes for a good piece of science are even higher. So, let’s see what this new paper has to offer.

A total of 26 patients participated in this acupuncture ‘trial’, receiving a course of weekly treatments that ranged from 1 to 14 weeks. The average number of treatments was five. The Edmonton Symptom Assessment Scale (ESAS) was used to assess the severity of pain, tiredness, nausea, depression, anxiety, drowsiness, appetite, well-being, and dyspnoea. A two-tailed, paired t test was applied to the data to compare symptom scores pre- versus post-acupuncture treatment. Patients enrolled in All Care Hospice’s home care program were given the option to receive acupuncture to supplement usual care offered by the hospice team. Treatment was provided by licensed acupuncturists in the patient’s place of residence.

The results indicated that 7 out of 9 symptoms were significantly improved with acupuncture, the exceptions being drowsiness and appetite. Although the ESAS scale demonstrated a reduction in symptom severity post-treatment for both drowsiness and appetite, this reduction was not found to be significant.

At tis stage, I have lost most of my hopes for good science. This is not a ‘trial’ but a glorified case-series. There is no way that the stated aim can be pursued with this type of methodology. There is no reason whatsoever to assume that the observed outcome can be attributed to acupuncture; the additional attention given to these patients is but one of several factors that are quite sufficient to explain their symptomatic improvements.

This is yet another disappointment then from the plethora of ‘research’ into alternative medicine that, on closer inspection, turns out to be little more than thinly disguised promotion of quackery. These days, I can bear such disappointments quite well – after all, I had many years to get used to them. What I find more difficult to endure is the anger that overcomes me when I read the authors’ conclusion: Acupuncture was found to be effective for the reduction and relief of symptoms that commonly affect patient QOL. Acupuncture effectively reduced symptoms of pain, tiredness, nausea, depression, anxiety, and shortness of breath, and enhanced feelings of well-being. More research is required to assess the long-term benefits and symptom reduction of acupuncture in a palliative care setting.

This is not disappointing; in my view, this is scientific misconduct by

  • the authors,
  • the institutions employing the authors,
  • the ethics committee that has passed the ‘research’,
  • the sponsors of the ‘research’,
  • the peer-reviewers of the paper,
  • the journal and its editors responsible for publishing this paper.

The fact that this sort of thing happens virtually every day in the realm of alternative medicine does not render this case less scandalous, it merely makes it more upsetting.

This article is hilarious, I think. It was written by Heike Bishop, a homeopath who works in Australia. Here she tries to advise colleagues how best to defend homeopathy and how to deal effectively with the increasingly outspoken criticism of homeopathy. Below is the decisive passage from her article; I have not changed or omitted a word, not even her grammatical or other mistakes [only the numbers in brackets were inserted by me; they refer to my comments added below]:

Getting up in the morning and hearing that all the television and radio station report that it is dangerous for people to see their homoeopath, is utterly heart breaking. Even more so because I grew up in East Germany where the government suppressed free speech and anything that was off the beaten path [1]. So what can we do in times like these?

First of all, watch out for Government inquiries. History has shown that they are usually not favourable towards homoeopathy [2] unless you live in Switzerland [3]. It is vitally important in times like these to put differences aside amongst our professional peers. Every association should be mobilised to take an active and ONGOING role to educate and advertise the benefits of homoeopathy [4]. If things have gone too far already, talk about freedom of choice [5]. Write articles and join blogs talking about what you can do specifically for certain conditions [6].  Encourage your patients to tell their success stories in blogs and other social media forums [7]. It is in most cases utterly useless to engage in any conversation [8] online with trolls [9].

Try to develop a calloused skin when it comes to criticism. Your patients don’t want to hear how difficult it is to be a homeopath [10], they want you to be in control and to be reassured that their treatment continues [11]. When someone asks you to comment on an attack on homoeopathy, put your best smile on and state how threatened the pharmaceutical industry must be to resort to such tactics [12].

Staphysagria is indeed a good remedy. Hahnemann also knew its benefits and even alternated it with Arsenicum the day his first wife died and he got a letter that the hospital built in his name allowed patients to choose their treatment between allopathy and homoeopathy [13]. That was the only time he took two remedies on the same day! [14]

Find out what you can about your country’s own internet trolls [15]. However, don’t underestimate their effectiveness in swaying popular opinion [16]. There is no denying that their methods are very effective [17]. It doesn’t matter how ludicrous their comments are, don’t go into direct explanation [18]. Learn from the enemy [19] and repeat a positive message over and over again so it can’t be contorted [20].

Our colleges should support post-graduate studies featuring marketing and media courses [21]. I once met a Homoeopath from the UK and she pointed out that part of the training in the UK is for students to hold homoeopathic first aid courses to promote homoeopathy [22]. Everyone is different – some of us are happy to stand in front of an audience others choose the pen as their sword [23]. The main thing is to do something to save the image of our healing art [24].

  1. Is she implying that facing criticism of homeopathy is akin to living in a totalitarian state? Or that criticism is a violation of free speech?
  2. I wonder why this is so – nothing to do with the evidence, I presume?
  3. Does she refer to the famous ‘Swiss Government report’ which was not by the Swiss Government at all?
  4. ‘Advertise and educate’ seems to be homeopathic speak for ‘MISLEAD’
  5. Good idea! Freedom of choice is a perfect argument (in this case, my choice would be to have a bottle of champagne at around 6 pm every day – on the NHS, of course).
  6. Certain conditions??? And I thought homeopaths do not treat conditions, only whole people.
  7. And forbid them to disclose stories where things did not work out quite so well?
  8. Very wise! Conversations are fraught with the danger of being found wrong.
  9. Critics are not critics but ‘trolls’ – makes sense.
  10. I would have thought that practising as a homeopath is not difficult at all – in most countries, they don’t even check whether you can spell the name correctly.
  11. Is it not rather the homeopath who wants the treatment to continue – after all, it is her livelihood?
  12. Ah yes, BIG PHARMA, the last resort of any quack!
  13. Did she not just praise patient choice as an important virtue?
  14. Hahnemann was famously cantankerous and argumentative all his life; does that mean that his remedies did not work?
  15. Homeopaths might need that for your ad hominem attacks.
  16. Never underestimate the power of truth!!!
  17. This might show that it is you and not the ‘trolls’ who are ludicrous.
  18. Particularly as there are no direct explanations for homeopathy.
  19. First the critics were ‘trolls’, now they have been upgraded to ‘enemy’! Is it really a war?
  20. You need to repeat it at least regularly so that eventually you believe it yourself.
  21. Are marketing and media a substitute for evidence?
  22. Really, first aid? Do homeopaths know what this is? Obviously not!
  23. But real clinicians, homeopaths call them allopaths, are quite happy simply with effective treatments that help patients to improve.
  24. And I thought the main thing was to treat patients with the most effective therapies available.

ENOUGH JOKING AND SARCASM!

There is, of course, a very serious message in all of this: when under pressure, homeopaths seem to think of all sorts of things in their (and homeopathy’s) defense – some more rational than others – but the ideas that criticism might be a good way to generate progress, and that a factual debate about the known facts might improve healthcare, do not seem to be amongst them.

One of the questions that I hear regularly is: ‘What happened to your research unit at Exeter?’ Therefore it might be a good idea to put the full, shameful story on this blog.

After the complaint by Prince Charles’ secretary to my Vice Chancellor alleging that I had breached confidentiality over the Smallwood report, my University conducted a 13 months investigation into my actions. At the end of it, I was declared innocent as charged (it should have been clear from a 10 minute discussion that I had done nothing wrong: I had not disclosed any information from the report, and even if I had, it would have been a matter of public interest and medical ethics to blow the whistle. However, the Vice Chancellor never once bothered to talk to me.). Subsequently, all support that I had once enjoyed broke down, my staff’s contracts were terminated, and I eventually had to take early retirement (full details of this part of the story can be found in ‘A SCIENTIST IN WONDERLAND’).

A few months later, a new dean was appointed at my medical school. The new man seemed to have a lot more understanding for my situation than his predecessor. Provided that I accept to go into early retirement, he offered to re-employ me for one year (half time) to help him find a successor for my position.

I did accept because, above everything, I wanted to prevent the closure of my unit. We then developed criteria for advertising the post and conducted two rounds of advertisements. Several candidates applied but none them seemed suited in our view. Eventually we did find several experts who were promising; one even came to Exeter from abroad and had detailed talks with the dean and several other people.

However, Exeter was unwilling to equip my potential successor with any funds to speak of. The suggestion was to appoint the new chair with the onus to raise all the necessary funds himself. This is a proposition that no well-qualified academic at the professorial level can possibly find attractive. Consequently, the candidates all declined.

Meanwhile, there had been an initiative by several altruistic UK public figures and friends to raise funds for the new chair and thus save my unit from closure. Sadly, however, these activities did not generate in the necessary cash. When my year of half-time re-employment had expired, I left Exeter and my unit disappeared for good.

To the present day, I am not at all sure what the true intentions of Exeter had been during this final stage.

  • Was I offered re-employment simply to keep me sweet?
  • Did they fear that I would otherwise sue them or cause a public scandal?
  • Did they truly believe they could find a suitable successor?
  • If so, why did they not put up the money?

I do not expect to ever find conclusive answers for any of these questions. However, I do know what, in an ideal world, should have become of my unit. If it had been for me to decide, I would have equipped the chair with the necessary core funds and appointed an ethicist with a documented interest in alternative medicine as the new professor. I see two main reasons for this perhaps less than obvious choice:

  • In my experience, Exeter would greatly benefit from an ethicist to give them guidance on a range of matters.
  • After two decades of being involved in alternative medicine research, I have become convinced that this field foremost needs the input of a critical ethicist.

In case either of these last two statements puzzles you, I recommend you read ‘A SCIENTIST IN WONDERLAND’.

For ‘my’ journal FACT, I review all the new articles that have emerged on the subject of alternative medicine on a monthly basis. Here are a few impressions and concerns that this activity have generated:

  • The number of papers on alternative medicine has increased beyond belief: between the year 2000 and 2010, there was a slow, linear increase from 335 to 610 Medline-listed articles; thereafter, the numbers exploded to 1189 (2011), 1674 (2012) and 2236 (2013).
  • This fast growing and highly lucrative ‘market’ has been cornered mainly by one journal: ‘EVIDENCE BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE’ (EBCAM), a journal that I mentioned several times before (see here, for instance). In 2010, EBCAM published 76 papers, while these figures increased to 546, 880 and 1327 during the following three years.
  • Undeniably, this is big business, as authors have to pay tidy sums each time they get published in EBCAM.
  • The peer-review system of EBCAM is farcical: potential authors who send their submissions to EBCAM are invited to suggest their preferred reviewers who subsequently are almost invariably appointed to do the job. It goes without saying that such a system is prone to all sorts of serious failures; in fact, this is not peer-review at all, in my opinion, it is an unethical sham.
  • As a result, most (I estimate around 80%) of the articles that currently get published on alternative medicine are useless rubbish. They tend to be either pre-clinical investigations which never get followed up and are thus meaningless, or surveys of no relevance whatsoever, or pilot studies that never are succeeded by more definitive trials, or non-systematic reviews that are wide open to bias and can only mislead the reader.
  • Nowadays, very few articles on alternative medicine are good enough to get published in mainstream journals of high standing.

The consequences of these fairly recent developments are serious:

  • Conventional scientists and clinicians must get the impression that there is little research activity in alternative medicine (while, in fact, there is lots) and that the little research that does emerge is of poor quality.
  • Consequently alternative medicine will be deemed by those who are not directly involved in it as trivial, and the alternative medicine journals will be ignored or even become their laughing stock.
  • At the same time, the field of alternative medicine and its proponents (the only ones who might actually be reading the plethora of rubbish published in alternative medicine journals) will get more and more convinced that their field is supported by an ever- abundance of peer-reviewed, robust science.
  • Gradually, they will become less and less aware of the standards and requirements that need to be met for evidence to be called reliable (provided they ever had such knowledge in the first place).
  • They might thus get increasingly frustrated by the lack of acceptance of their ‘advances’ by proper scientists – an attitude which, from their perspective, must seem unfair, biased and hostile.
  • In the end, conventional and alternative medicine, rather than learning from each other, will move further and further apart.
  • Substantial amounts of money will continue to be wasted for research into alternative medicine that, whenever assessed critically, turns out to be too poor to advance healthcare in any meaningful way.
  • The ones who medicine should be all about, namely the patients who need our help and rely on the progress of research, are not well served by these developments.

In essence this suggests, I think, that alternative medicine is ill-advised and short-sighted to settle for standards that are so clearly below those generally deemed acceptable in medicine. Similarly, conventional medicine does a serious disfavour to progress and to us all, if it ignores or tolerates this process.

I am not at all sure how to reverse this trend. In the long-term, it would require a change of attitude that obviously is far from easy to bring about. In the short-term, it might help, I think, to de-list journals from Medline that are in such obvious conflict with publication ethics.

A new RCT of Reiki healing has been published by US authors from the following institutions: Union Institute & University, Psychology Program, Brattleboro, VT, Coyote Institute, Augusta and Bangor, ME, Eastern Maine Medical Center and Acadia Hospital, Bangor, ME, University of New England College of Osteopathic Medicine, Biddeford, ME, Coyote Institute, Orono, ME. The purpose of this study was to determine if 30 minutes of healing touch could reduce burnout in community mental health clinicians.

The authors utilized a crossover design to explore the efficacy of Reiki versus sham Reiki, a pseudo treatment performed by volunteers who had no experience with Reiki and pretended to be healers vis-à-vis the patients. This sham control intervention was designed to mimic true Reiki.

Subjects were randomized to whether they started with Reiki or sham. The Maslach Burnout Inventory-Human Services Survey (MBI-HSS) and the Measure Your Medical Outcome Profile Version 2 (MYMOP-2) were used as outcome measures. Multilevel modeling was used to represent the relations among variables.

The results showed that real Reiki was significantly better than sham Reiki in reducing burnout among community mental health clinicians. Reiki was significant in reducing depersonalization, but only among single people. Reiki reduced the primary symptom on the MYMOP also only among single people.

The authors concluded that the effects of Reiki were differentiated from sham Reiki. Reiki could be helpful in community mental health settings for the mental health of the practitioners.

My team has published on Reiki (see here and here, for instance), and on this blog I have repeatedly been expressed my doubts that Reiki is more than an elaborate placebo (see here and here, for instance). Do these new results mean that I need to eat my words and henceforth praise the wonders of Reiki? No, I don’t think so!

Having conducted studies on ‘energy healing’ myself, I know only too well of the many pitfalls and possibilities of generating false-positive findings with such research. This new study has many flaws, but we need not look far to find the reason for the surprising and implausible finding. Here is my explanation why this study suggests one placebo to be superior to another placebo.

The researchers had to recruit 16 Reiki healers and several non-Reiki volunteers to perform the interventions on the small group of patients. It goes without saying that the Reiki healers were highly motivated to demonstrate the value of their therapy. This means they (unintentionally?) used verbal and non-verbal communication to maximise the placebo effect of their treatment. The sham healers, of course, lacked such motivation. In my view, this seemingly trivial difference alone is capable of producing the false-positive result above.

There are, of course, ways of minimising the danger of such confounding. In our own study of ‘energy healing’ with sham healers as controls, for instance, we instructed both the healers and the sham healers to abstain from all communication with their patients, we filmed each session to make sure, and we asked each patient to guess which treatment they had received. None of these safeguards were incorporated in the present study – I wonder why!
