One would be hard-pressed to find a form of so-called alternative medicine (SCAM) that is not being promoted for back pain: chiropractic, osteopathy, reflexology, naturopathy, homeopathy … you name it. Intriguingly, they all seem to generate similarly good – a realist would say bad – results. Faced with this large but largely ineffective options, one can hardly be surprised that enterprising innovators look for their own solutions. And few are more enterprising then this patient from Ireland who decided to devise his very own and highly unusual back pain therapy.

The 33 year old male with a history of back problems was seen complaining of severe, sudden onset lower back pain. He reported lifting a heavy steel object 3 days prior and his symptoms had progressed ever since. A physical exam of revealed an erythematous papule with a central focus on the medial aspect of his right upper limb.

The patient disclosed that he had – independent of any medical advice – intravenously injected his own semen as an innovative method to alleviate his back pain (a truly naturopathic approach, if there ever was one!). He also revealed that he had previously injected one monthly “dose” of semen for 18 consecutive months using a hypodermic needle purchased online.

On this occasion, the patient had tried to inject three “doses” of semen intra-vascularly and intra-muscularly. The erythema extended medially along his upper limb over the course of the following 24 hours.

It became indurated around the injection site where he had failed multiple attempts at injecting the semen thus causing an extravasation of his sperm into the soft tissues. Blood tests demonstrated a C-reactive protein of 150mg/L and white cell count of 13×109/L. The patient was immediately commenced on intravenous antimicrobial treatment after seeking advice regarding appropriate cover. A radiograph of the limb was obtained to exclude retained foreign body and it demonstrated a subcutaneous emphysema.

This patient’s back pain improved over the course of his inpatient stay. He opted to discharge himself without availing of an incision and drainage of the local collection.


For me, the most fascinating aspect of this story is the fact that the patient had previously treated himself 18 (!) times before this little mishap occurred.

Why?, one may well ask. The answer has, I think, been provided by legions of proponents of diverse forms of SCAM: BECAUSE IT WORKED! PEOPLE ARE NOT STUPID; THEY DON’T CONTINUE TREATMENTS, IF THEY DON’T WORK.

So, either intravenous semen injections are an effective way to control back pain – in which case, I recommend that NICE look into it – or…


(I know which explanation I favour)

Once again, I am indebted to the German homeopathy lobbyist, Jens Behnke (research officer at the Karl and Veronica Carstens-Foundation); this time for alerting me via a tweet to the existence of the ‘Institute for Scientific Homeopathy’ run by Dr K Lenger. Anyone who combines the terms ‘scientific’ and ‘homeopathy’ has my full attention.

The institution seems to be small (too small to have its own website); in fact, it seems to have just one member: Dr Karin Lenger. But size is not everything! Lenger has achieved something extraordinary: she has answered the questions that have puzzled many of us for a long time; she has found the ‘modus operandi’ of homeopathy by discovering that:

  • Homeopathy is a regulation therapy that acts (and reacts) as per the principle of resonance to deal hypo- and hyper-functions of pathological pathways.
  • As per resonance principle, the fundamental principles of homeopathy have the same frequencies so that the resonance principle can work.
  • Pathological pathways are cured by using their highly potentized substrates, inhibitors, and enzymes.
  • The efficacy of homeopathy now has a scientific base and is completely explained by applying biochemical and biophysical laws.

Progress at last!

If that is not noteworthy, what is?

But there is more!

This website, for instance, explains that Lenger Karin Dr.rer.nat., pursued Diploma in Biochem, studied Biochemistry at the Universities of Tubingen and Cologne. Her research topics revolved around enzymatic gene regulation, cancer research, enzymatic mechanisms of steroid hormones at the Medical University of Lubeck. In 1987 she became a Lecturer for Homeopathy at DHU ((Deutsche Homöopathie Union = German Homeopathy Union). Since 1995 she worked as a Homeopathic Practitioner and developed the “biochemical homeopathy” by using highly potentized substrates of pathological enzymes for her patients. She detected magnetic photons in high homeopathic potencies by two magnetic resonance methods and developed a model of physical and biochemical function of homeopathy.

Karin Lenger detected magnetic photons in highly diluted and potentized homeopathic remedies. Since the living body is an electromagnetic wavepackage (Einstein), the homeopathic law of Similars (Hahnemann 1755-1843) can be expressed as: the frequencies of the patient must match the frequencies of the remedies. Homeopathy is a regulation therapy curing hypo and hyperfunction of a pathological pathway by resonance: highly potentized substrates, inhibitors, enzymes, receptors of the distinct pathological pathways cure according to biochemical rules: A homeopathic symptom picture is obtained by poisoning a volunteer with a toxin. Simultaneously he develops psychological symptoms, the toxicological pathway and e.g. frequencies I-V. The highly potentized toxin has the frequencies I-V. The patient has symptoms as if he was poisoned by the toxin: during his illness he developed the toxicological pathway, frequencies I-V and psychological symptoms. The potentized toxin cures simultaneously the patient’s frequencies by resonance, his pathological pathway and the psychological symptoms. A stitch of honey bee, apis mellifica, causes a red oedema; a patient developing a red oedema at the finger-joint by rheumatism is cured by highly potentized Apis mellifica. Paralyses caused by a lack of the neurotransmitter acetylcholine bound to the acetylcholine-receptor at the post-synapsis can be healed by using these potentized remedies: the venom of cobra, Naja tripudians containing the receptor’s irreversible inhibitor cobrotoxin, the reversible inhibitor Atropine and Acetylcholine, daily applied. The availability of acetylcholine is maintained by glycolysis and fatty acid oxidation. This can be supported by giving these remedies: Lecithin, Lipasum, Glycerinum, Glucosum and Coenzyme A.

And in case, you are not yet fully convinced, a recent publication is bound to ball you over. Here is its abstract, if you need more, the link allows you to read the full paper as well:

Homeopathy, a holistic therapy, is believed to cure only acute symptoms of a beginning illness according to the Laws of Similars; but not deep, bleeding, septic wounds. The homeopaths refuse to heal according to special medical indications. Based on Lenger’s detection of magnetic photons in homeopathic remedies a biochemical and biophysical model of homeopathic healing was developed Biochemical, pathological pathways can be treated by their highly potentized substrates and inhibitors. Three groups of patients with moderate, severe and septic wounds had been successfully treated with the suitable remedies depending on the biochemical pathological state.


Do I sense a Nobel Prize in the offing?


Lenger’s clinical trial is baffling. But much more impressive are the ‘magnetic photons’ and the reference to Einstein. This is even more significant, if we consider what the genius (Einstein, not Lenger!) is reported to have said about homeopathy:  Einstein reflected for a little while and then said: “If one were to lock up 10 very clever people in a room and told them they were only allowed out once they had come up with the most stupid idea conceivable, they would soon come up with homeopathy.”

The notion that ‘chiropractic adds years to your life’ is often touted, particularly of course by chiropractors (in case you doubt it, please do a quick google search). It is logical to assume that chiropractors themselves are the best informed about what they perceive as the health benefits of chiropractic care. Chiropractors would therefore be most likely to receive some level of this ‘life-prolonging’ chiropractic care on a long-term basis. If that is so, then chiropractors themselves should demonstrate longer life spans than the general population.

Sounds logical?

Perhaps, but is the theory supported by evidence?

Back in 2004, a chiropractor, Lon Morgan,  courageously tried to test the theory and published an interesting paper about it.

He used two separate data sources to examine the mortality rates of chiropractors. One source used obituary notices from past issues of Dynamic Chiropractic from 1990 to mid-2003. The second source used biographies from Who Was Who in Chiropractic – A Necrology covering a ten year period from 1969-1979. The two sources yielded a mean age at death for chiropractors of 73.4 and 74.2 years respectively. The mean ages at death of chiropractors is below the national average of 76.9 years; it also is below the average age at death of their medical doctor counterparts which, at the time, was 81.5.

So, one might be tempted to conclude that ‘chiropractic substracts years from your life’. I know, this would be not very scientific – but it would probably be more evidence-based than the marketing gimmick of so many chiropractors trying to promote their trade by saying: ‘chiropractic adds years to your life’!

In any case, Morgan, the author of the paper, concluded that this paper assumes chiropractors should, more than any other group, be able to demonstrate the health and longevity benefits of chiropractic care. The chiropractic mortality data presented in this study, while limited, do not support the notion that chiropractic care “Adds Years to Life …”, and it fact shows male chiropractors have shorter life spans than their medical doctor counterparts and even the general male population. Further study is recommended to discover what factors might contribute to lowered chiropractic longevity.

Another beautiful theory killed by an ugly fact!

The ‘Dunning Kruger Effect‘ (DuKE) has been discussed here before. The DuKE means that, the less you know, the less able you are to recognize how little you know, and the less likely you are to recognize your limitations. Consequently, your confidence in yourself is inflated and you believe you are more competent than your opponent. Expressed differently:

  • Incompetence prevents the recognition of incompetence.
  • Too stupid to doubt.

A recent paper brilliantly shows the DuKE in action; here is its abstract

There is widespread agreement among scientists that genetically modified foods are safe to consume and have the potential to provide substantial benefits to humankind. However, many people still harbour concerns about them or oppose their use. In a nationally representative sample of US adults, we find that as extremity of opposition to and concern about genetically modified foods increases, objective knowledge about science and genetics decreases, but perceived understanding of genetically modified foods increases. Extreme opponents know the least, but think they know the most. Moreover, the relationship between self-assessed and objective knowledge shifts from positive to negative at high levels of opposition. Similar results were obtained in a parallel study with representative samples from the United States, France and Germany, and in a study testing attitudes about a medical application of genetic engineering technology (gene therapy). This pattern did not emerge, however, for attitudes and beliefs about climate change.

As I have stated before, I suspect the DuKE can explain much of what is going on in the realm of SCAM (so-called alternative medicine). So much so that I am tempted to re-write part of the above abstract as follows:

As extremity of belief in SCAM increases, objective knowledge about science and medicine decreases. In parallel, perceived understanding of science and medicine increases. Extreme believers in SCAM know the least, but think they know the most. Moreover, the relationship between self-assessed and objective knowledge shifts from positive to negative at high levels of SCAM-belief.

Yes, yes, I know. You are absolutely correct: this is little more than speculation! And I also realise, of course, that not everyone can have a full understanding of SCAM, medicine and science; however, if someone has a strong interest in (plus a strong opinion of) these matters, it would be advisable to read up about at least the most basic facts.

In case you disapprove, please do have a look at some of the recent comments on this blog or assess what some of the most famous proponents of SCAM tell the public, and I am confident that you will begin to suspect that my speculation might be not that far off the mark.

Most chiropractors claim they can effectively treat a wide range of conditions. I have looked far and wide but I fail to see sound evidence to show that this assumption is true. On a good day, I might agree that chiropractic works for back pain (but this would need to be a very good day and I would need to close at least one eye) – and that’s basically it! Unsurprisingly, chiropractors vehemently disagree with me. Yet, they have an all too obvious conflict of interest in that question and, therefore, they are unlikely to be objective.

One regular commentator of this blog recently reminded me that the UK ‘ADVERTISING STANDARDS AUTHORITY’ (ASA) state on their website that based on all evidence submitted and reviewed to date, the ASA and CAP accept that chiropractors may claim to treat the following conditions:

  • Ankle sprain (short term management)
  • Cramp
  • Elbow pain and tennis elbow (lateral epicondylitis) arising from associated musculoskeletal conditions of the back and neck, but not isolated occurrences
  • Headache arising from the neck (cervicogenic
  • Joint pains
  • Joint pains including hip and knee pain from osteoarthritis as an adjunct to core OA treatments and exercise
  • General, acute & chronic backache, back pain (not arising from injury or accident)
  • Generalised aches and pains
  • Lumbago
  • Mechanical neck pain (as opposed to neck pain following injury i.e. whiplash)
  • Migraine prevention
  • Minor sports injuries
  • Muscle spasms
  • Plantar fasciitis (short term management)
  • Rotator cuff injuries, disease or disorders
  • Sciatica
  • Shoulder complaints (dysfunction, disorders and pain)
  • Soft tissue disorders of the shoulder
  • Tension and inability to relax

This is an impressive yet very odd list:

  • Why is ‘joint pain’ listed twice?
  • Can lateral epicondylitis arise from musculoskeletal conditions of the back and neck?
  • What exactly are ‘generalised aches and pains’?
  • Isn’t lumbago and backache the same?
  • Are ‘minor sports injuries’ (including a cut, bruise or haematoma?) a category that is well-defined?
  • What is a ‘soft tissue disorders of the shoulder’

But let’s not be pedantic. Let’s assume these are all defined conditions that need to be treated. The problem still remains that there is hardly any good evidence that they can be effectively treated by chiropractic spinal manipulation (in case you disagree, please post the evidence in the comments section).

And here we come to the crux of the matter, I think.

Chiropractors would say that they use so much more than spinal manipulations.

  • For a sport injury, they might apply an ice-pack.
  • For the inability to relax, they might give a massage.
  • For rotator cuff problems, they might administer exercises.
  • For tennis elbow, they might recommend immobilizing the joint.
  • Etc., etc.

But that’s not chiropractic!

Yes, it is what we do, insist the chiropractors.

I do not doubt it, but survey after survey shows that chiropractors treat almost all their patients with spinal manipulation. And the history of chiropractic is purely based on spinal manipulation. Yes, today they also use treatments borrowed from other disciplines, yet spinal manipulation is the treatment that defines them.

Let me try an example to make my point clear. Imagine a surgeon who specialises in an obsolete type of operation (e.g. ligation of the mammary artery as a treatment of coronary artery disease). Following the chiro-logic, he could claim that:

  • my approach is not ineffective because I do so much more than just operate,
  • I also prescribe medications,
  • I give dietary advice,
  • I give nutritional advice,
  • I recommend relaxation,
  • I suggest regular exercise.

And the results would, of course, show that many of his patients benefit from all this.

Does that mean our surgeon provides effective care for his patients?

Similarly, crystal healing could be seen as being effective, because some crystal healers tell their obese patients to eat less and exercise more?

So, the above-cited list of claims that the ASA now allows UK chiropractors to make is either way too long or much too short – in any case, it is nonsense. If we base it on the proven effectiveness of spinal manipulation, it must be very short indeed. If we base it on everything chiropractors might do in addition, it is far too short; in this case, it should include everything in the medical textbooks from AIDS to ZOSTER (I cannot imagine many conditions for which life-style advice, exercise or cryotherapy [for pain-control] etc. would not be helpful).

My conclusions from all this are as follows:

  • Chiropractors have tried to reinvent themselves by borrowing some treatments from other healthcare professions.
  • They have done this, I suspect, to avoid being judged by their largely ineffective hallmark intervention, spinal manipulation. The move may be commercially clever, but it is nevertheless transparently nonsensical and wholly unconvincing.
  • Chiropractors must be judged not by the treatments they borrowed and might use occasionally, but by the only therapy that is inherent to chiropractic: spinal manipulation.
  • And spinal manipulation is certainly not effective for a wide range of conditions.

Probiotics (live microorganisms for oral consumption) are undoubtedly popular, not least they are being cleverly promoted as a quasi panacea. But are they as safe as their manufacturers try to convince us? A synthesis and critical evaluation of the reports and series of cases on the infectious complications related to the ingestion of probiotics was aimed at finding out.

The authors extensive literature searches located 60 case reports and 7 case series including a total of 93 patients. Fungemia was the most common infectious complications with 35 (37.6%) cases. The genus Saccharomyces was the most frequent with 47 (50.6%) cases, followed by Lactobacillus, Bifidobacterium, Bacillus, Pedioccocus and Escherichia with 26 (27.9%), 12 (12.8%), 5 (5.4%), 2 (2.2%) and 1 (1.1%) case, respectively. Adults over 60 years of age, Clostridium difficile colitis, antibiotic use and Saccharomyces infections were associated with overall mortality. HIV infections, immunosuppressive drugs, solid organ transplantation, deep intravenous lines, enteral or parenteral nutrition were not associated with death.

The authors concluded that the use of probiotics cannot be considered risk-free and should be carefully evaluated for some patient groups.

Other authors have previously warned that individuals under neonatal stages and/or those with some clinical conditions including malignancies, leaky gut, diabetes mellitus, and post-organ transplant convalescence likely fail to reap the benefits of probiotics. Further exacerbating the conditions, some probiotic strains might take advantage of the weak immunity in these vulnerable groups and turn into opportunistic pathogens engendering life-threatening pneumonia, endocarditis, and sepsis. Moreover, the unregulated and rampant use of probiotics potentially carry the risk of plasmid-mediated antibiotic resistance transfer to the gut infectious pathogens. 

And yet another review had concluded that the adverse effects of probiotics were sepsis, fungemia and GI ischemia. Generally, critically ill patients in intensive care units, critically sick infants, postoperative and hospitalized patients and patients with immune-compromised complexity were the most at-risk populations. While the overwhelming existing evidence suggests that probiotics are safe, complete consideration of risk-benefit ratio before prescribing is recommended.

Proponents of probiotics will say that these risks are rare and confined to small groups of particularly vulnerable patients. This may well be so, but in view of the often uncertain benefits of probiotics, the incessant hype and aggressive marketing, I find it nevertheless important to keep these risks in mind.

As with any therapy, the question must be, does this treatment really generate more good than harm?

I would warn every parent who thinks that taking their child to a chiropractor is a good idea. For this, I have three main reasons:

  1. Chiropractic has not been shown to be effective for any paediatric condition.
  2. Chiropractors often advise parents against vaccinating their children.
  3. Chiropractic spinal manipulations can cause harm to kids.

The latter point seems to be confirmed by a recent PhD thesis of which so far only one short report is available. Here are the relevant bits of information from it:

Katie Pohlman has successfully defended her PhD thesis, which focused on the assessment of safety in pediatric manual therapy. As a clinical research scientist at Parker University, Dallas, Texas, she identified a lack of prospective patient safety research within the chiropractic population in general and investigated this deficit in the paediatric population in particular.

Pohlman used a cross-sectional survey to assess the barriers and facilitators for participation in a patient safety reporting system. At the same time, she also conducted a randomized controlled trial comparing the quantity and quality of adverse event reports in children under 14 years receiving chiropractic care.

The RCT recruited 69 chiropractors and found adverse events reported in 8.8% and 0.1% of active and passive surveillance groups respectively. Of the adverse events reported, 56% were considered mild, 26% were moderate and 18% were severe. The frequency of adverse events was more common than previously thought.

This last sentence from the report is somewhat puzzling. Our systematic review of the risks of spinal manipulation showed that data from prospective studies suggest that minor, transient adverse events occur in approximately half of all patients receiving spinal manipulation. The most common serious adverse events are vertebrobasilar accidents, disk herniation, and cauda equina syndrome. Estimates of the incidence of serious complications range from 1 per 2 million manipulations to 1 per 400,000. Given the popularity of spinal manipulation, its safety requires rigorous investigation.

The 8.8% reported by Pohlman are therefore not even one fifth of the average incidence figure reported previously in all age groups.

What could be the explanation for this discrepancy?

There are, of course, several possibilities, including the fact that infants cannot tell the clinician when their pain has increased. However, the most likely one, in my view, lies in the fact that RCTs are wholly inadequate for investigating risks because they typically include far too few patients to generate reliable incidence figures about adverse events. More importantly, clinicians included in such studies are self-selected (and thus particularly responsible/cautious) and are bound to behave most carefully while being part of a clinical trial. Therefore it seems possible – I would speculate even likely – that the 8.8% reported by Pohlman is unrealistically low.

Having said that, I do feel that the research by Kathie Pohlman is a step in the right direction and I do applaud her initiative.

The German Association of Medical Homeopaths (Deutscher Zentralverein homöopathischer Ärzte (DZVhÄ)) have recently published an article where, amongst other things, they lecture us about evidence-based medicine (EBM). If you feel that this might be a bit like an elephant teaching Fred Astaire how to step-dance, you could have a point. Here is their relevant paragraph:

… das Konzept der modernen Evidenzbasierte Medizin nach Sackett [stützt sich] auf drei Säulen: auf die klinischen Erfahrung der Ärzte, auf die Werte und Wünsche des Patienten und auf den aktuellen Stand der klinischen Forschung. Homöopathische Ärzte wehren sich gegen einen verengten Evidenzbegriff der Kritiker, der Evidenz allein auf die Säule der klinischen Forschung bzw. ausschließlich auf RCT verengen möchte und die anderen beiden Säulen ausblendet. Experten schätzen, dass bei einer solchen Auffassung von EbM rund 70 Prozent aller Leistungen der GKV nicht evidenzbasiert sei. Nötiger als eine Homöopathie-Debatte hat die deutsche Ärzteschaft aus unserer Sicht eine klare Verständigung darüber, welcher Evidenzbegriff nun gilt.

For those who cannot understand the full splendour of their argument because of the language problem, I translate as literally as I can:

… the concept of the modern EBM according to Sackett is based on three pillars: on the clinical experience of the doctors, on the values and wishes of the patient and on the current state of the clinical research. Homeopaths defend themselves against the narrowed understanding of ‘evidence’ of the critics which aims at narrowing evidence solely to the pillar of the clinical research or exclusively to RCT, while eliminating the other two pillars. Experts estimate that, with such an view of EBM, about 70% of all treatments reimbursed by our health insurances would not be evidence-based. We feel that we more urgently need a clear understanding which evidence definition applies than a debate about homeopathy.


So, where is the hilarity in this?

I don’t know about you, but I find the following things worth a giggle:

  1. ‘narrowed understanding of evidence’ – this is a classical strawman; non-homeopaths tend to apply Sackett’s definition which states that ‘evidence-based medicine is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients. The practice of evidence-based medicine means integrating individual clinical experience with the best available external clinical evidence from systematic research‘;
  2. as we see, Sackett’s definition is quite different from the one cited by the homeopaths;
  3. the three pillars cited by the homeopaths are those subsequently developed for Evidence Based Practice (EBP) and include: A) patient values, B) clinical expertise and C) external best evidence;
  4. as we see, these three pillars are also not quite the same as those suggested by the homeopaths;
  5. non-homeopaths do certainly not aim at eliminating the ‘other two pillars’;
  6. current best evidence clearly includes much more than just RCTs – to mention RCTs in this context therefore suggests that the ones guilty of narrowing anything might, in fact, be the homeopaths;
  7. even if it were true that 70% of reimbursable treatments are not evidence-based, this would hardly be a good reason to employ homeopathic remedies of which 100% are not even remotely evidence-based;
  8. unbeknown to the German homeopaths, the discussion about a valid definition of EBM has been intense, is as old as EBM itself, and would by now probably fill a mid-size library;
  9. this discussion does, however, in no way abolish the need to bring the debate about homeopathy to the only evidence-based conclusion possible, namely the discontinuation of reimbursement of this and all other bogus therapies.

In conclusion, I do thank the German homeopaths for being such regular contributors to fun and hilarity. I shall miss them, once they have fully understood EBM and are thus compelled to stop prescribing placebos.

Having been frantically searching for a decent quality study reporting a positive result, I am delighted to announce that I might have had some luck.

This study examined the effects of whole-body massage on knee osteoarthritis, compared to active control (light-touch) and usual care. Assessments were done at baseline and weeks 8, 16, 24, 36, and 52. Subjects in massage or light-touch groups received eight weekly treatments each lasting one hour, then were randomized to biweekly intervention or usual care to week 52. The original usual care group continued to week 24. Analysis was performed on an intention-to-treat basis. Five hundred fifty-one screened for eligibility, 222 adults with knee osteoarthritis enrolled, 200 completed 8-week assessments, and 175 completed 52-week assessments.

The primary endpoint was the ‘Western Ontario and McMaster Universities Arthritis Index’. Visual analog pain scale, PROMIS Pain Interference, knee range of motion, and timed 50-ft walk were secondary outcome measures.

At 8 weeks, massage significantly improved WOMAC Global scores compared to light-touch and usual care. Massage also improved pain, stiffness, and physical function WOMAC subscale scores compared to light-touch and usual care. At 52 weeks, the omnibus test of any group difference in the change in WOMAC Global from baseline to 52 weeks was not significant, indicating no significant difference in change across groups. Adverse events were minimal.

The authors concluded that the efficacy of symptom relief and safety of weekly massage make it an attractive short-term treatment option for knee osteoarthritis. Longer-term biweekly dose maintained improvement, but did not provide additional benefit beyond usual care post 8-week treatment.

Massage therapy is supported by encouraging evidence from several systematic reviews, for instance:

  • One overview identified 31 systematic reviews of massage for pain control, of which 21 were considered high-quality. The most common type of pain included in systematic reviews was neck pain (n=6). Findings from high-quality systematic reviews describe potential benefits of massage for pain indications including labour, shoulder, neck, back, cancer, fibromyalgia, and temporomandibular disorder. However, no findings were rated as moderate- or high-strength.
  • A systematic review showed that massage therapy has promise for caner palliation: massage can alleviate a wide range of symptoms: pain, nausea, anxiety, depression, anger, stress and fatigue. However, the methodological quality of the included studies was poor, a fact that prevents definitive conclusions. The evidence is, therefore, encouraging but not compelling. The subject seems to warrant further investigations which avoid the limitations of previous studies.

So, should massage be recommended for knee osteoarthritis?

Yes and NO.

Yes, because it does seem to alleviate pain with only few adverse effects.

No, because it is merely symptomatic and does not cure the problem. Patients who want to treat the ‘root cause’ of knee osteoarthritis (which is often possible) ought to see an orthopaedic surgeon.

Come to think of it, this is almost a general rule: Patients who want to treat the ‘root cause‘ of any disease (which is often possible) ought to see a real doctor and not an alternative practitioner.

The 2018 World Federation of Chiropractic ACC Education Conference was held on 24-27 October in London. It resulted in several consensus statements developed by the attendees. I happen to know this from a short report that has just been published; it can be found here.

Of the 10 points made in this consensus, I find only the following noteworthy:

“Chiropractic education programs have an ethical obligation to support an evidence-based teaching and learning environment.”

Perhaps it is me – English is not my first language – but I find the phraseology used in this sentence strangely complicated and confusing. I have been a teacher of medical students for most of my life, but I am not sure what an ‘evidence-based teaching and learning environment’ is. I know what ‘evidence-based’ means, of course. However, what exactly is:

  • a teaching environment?
  • a learning environment?
  • and how does ‘evidence-based’ apply to either of the two?

Is there evidence that some environments are better suited than others for teaching?

Is there evidence that some environments are better suited than others for learning?

I suppose the answer must be YES!

The environment, i. e. the space and conditions in which teaching and learning happen should, for instance, be/include:

  • quiet,
  • not cramped,
  • not too cold,
  • not too hot,
  • equipped with ergometric chairs and desks,
  • well-lit,
  • there should be visual aids,
  • access to computers,
  • a library,
  • good mentoring and support,
  • etc.

So, the consensus of the education conference wanted to optimise the environmental conditions of teaching and learning for chiropractic lecturers and students? Most laudable, I must say!

But still, it seems like a missed opportunity for an ‘Education Conference’ not to have stated something about the content of teaching and learning. Personally, I find it a pity that they did not state: Chiropractic education programs have an ethical obligation to be evidence-based.

Or is that what they really wanted to say?

Naaahh … come to think of it … they cannot possibly make such a demand.


Because, in this case, they would have to teach students not to become chiropractors.
