Researchers from the ‘International Centre for Allied Health Evidence’, University of South Australia in Adelaide wanted to determine whether massage therapy is an effective intervention for back pain. They carried out extensive literature searches to identify all systematic reviews on the subject, analysed them critically and evaluated their methodological quality. Nine systematic reviews were found. Their methodological quality varied from poor to excellent. The primary research informing these systematic reviews was generally considered to be weak quality. The findings indicated that massage may be an effective treatment option when compared to placebo or active treatment options such as relaxation, especially in the short term. There were conflicting and contradictory findings for the effectiveness of massage therapy as a treatment of non-specific low back pain when compared against other manual therapies such as mobilization, standard medical care, and acupuncture.

The authors concluded that there is an emerging body of evidence, albeit small, that supports the effectiveness of massage therapy for the treatment of non-specific low back pain in the short term. Due to common methodological flaws in the primary research, which informed the systematic reviews recommendations arising from this evidence base should be interpreted with caution.

My own systematic review from 1999 (which the authors of this systematic review of systematic reviews seem to have missed) concluded that massage seems to have some potential as a therapy for low back pain. Indeed, there seems to be unanimous agreement that massage therapy is a promising treatment. Why then do massage therapists not finally get their act together and conduct a few more high quality primary studies? Currently, we have about as many reviews as trials! Doing even more reviews will not answer the question about effectiveness!!!

And it is a damn important question. Back pain is extremely common and extremely expensive for us all. At present, we have no optimal treatment. Chiropractors and osteopaths are claiming to have found a good solution, but many experts are not convinced by their evidence and argue that the risks of spinal manipulation might not outweigh its benefits. Massage, by contrast, is almost risk-free. Considering all this, I believe we need more trials with some urgency.

So, why are such trials not forthcoming? I realise that multiple hurdles have to be taken:

  • Clinical studies of that nature are expensive, and there is no obvious funding source.
  • Massage therapists usually do not have enough research expertise to pull off a sound study.
  • There are multiple methodological problems in conduction a definitive massage trial that might convince us all.

However, none of these obstacles are insurmountable. I suggest massage therapists team up with experts who know how to run clinical trials, hammer out a reasonable study design and approach government or other official funders for support. We need a definitive answers and we need them soon: is massage effective? which type of massage? for which patients? at which stage of non-specific low back pain?

Researchers from the ‘Complementary and Integrative Medicine Research, Primary Medical Care, University of Southampton’ conducted a study of Professional Kinesiology Practice (PKP) What? Yes, PKP! This is a not widely known alternative method.

According to its proponents, it is unique and a complete kinesiology system… It was developed by a medical doctor, Dr Bruce Dewe and his wife Joan Dewe in the 1980s and has been taught since then in over 16 countries around the world with great success… Kinesiology is a unique and truly holistic science and on the cutting edge of energy medicine. It uses muscle monitoring as a biofeedback system to identify the underlying cause of blockage from the person’s subconscious mind via the nervous system. Muscle monitoring is used to access information from the person’s “biocomputer”, the brain, in relation to the problem or issue and also guides the practitioner to find the priority correction in order to stimulate the person’s innate healing capacity and support their physiology to return to normal function. Kinesiology is unique as it looks beyond symptoms. It recognizes the flows of energy within the body not only relate to the muscles but to every tissue and organ that make the human body a living ever changing organism. These energy flows can be evaluated by testing the function of the muscles, which in turn reflect the body’s overall state of structural, chemical, emotional and spiritual balance. In this way kinesiology taps into energies that the more conventional modalities overlook and helps remove all the guesswork, doubt and hard work of subjective diagnostics. This is a revolutionary way to communicate with the body/mind connection. Through muscle monitoring and the use of over 300 fingermodes we can detect and correct the cause of the problem and effect a long lasting change for better health and wellbeing. Our posture could be considered to be the visual display unit from our internal bio-computer. Our posture / life energy improves as we upgrade the way we respond to life’s constant challenges and demands.

You do not understand? Let me make it crystal clear by citing another PKP-site:

PKP is a phenomenological practice – this means practitioners use manual muscle testing to demonstrate to the client how much or how little they are able to move in relation to their problem. PKP practitioners have tests for more than 100 muscles, and dozens of other tests that they do so they can clearly show you how your movement is affected by your problem. This muscle story shows a person how their life is unfolding, and it also helps to guide on how to transcend the situation and design a future which is more in alignment with nature and the laws of the cosmos… PKP is about living life more wisely.

In case you still have not understood what PKP is, you might have to watch this youtube clip. And now that everyone knows what it is, let us have a look at the new study.

According to its authors, it was an exploratory, pragmatic single-blind, 3-arm randomised sham-controlled pilot trial with waiting list control (WLC) which was conducted in the setting of a UK private practice. Seventy participants scoring ≥4 on the Roland and Morris Disability Questionnaire (RMDQ) were randomised to real or sham PKP receiving one treatment weekly for 5 weeks or a WLC. WLC’s were re-randomised to real or sham after 6 weeks. The main outcome measure was a change in RMDQ from baseline to end of 5 weeks of real or sham PKP.

The results show an effect size of 0.7 for real PKP which was significantly different to sham. Compared to WLC, both real and sham groups had significant RMDQ improvements. Practitioner empathy (CARE) and patient enablement (PEI) did not predict outcome; holistic health beliefs (CAMBI) did, though. The sham treatment appeared credible; patients did not guess treatment allocation. Three patients reported minor adverse reactions.

From these data, the authors conclude that real treatment was significantly different from sham demonstrating a moderate specific effect of PKP; both were better than WLC indicating a substantial non-specific and contextual treatment effect. A larger definitive study would be appropriate with nested qualitative work to help understand the mechanisms involved in PKP.

So, PKP has a small specific effect in addition to generating a sizable placebo-effect? Somehow, I doubt it! This was, according to its authors, a pilot study. Such an investigation should not evaluate the effectiveness of a treatment but the feasibility of the protocol. Even if we disregard this detail, I assume that the results indicate the effects of PKP to be essentially due to placebo. The small effect which the authors label as “specific” is, in my view, almost certainly caused by residual confounding and hidden biases.

One could also go one step further and say that any treatment that is shrouded in pseudo-scientific language and has zero plausibility is an ill-conceived candidate for a clinical trial of this nature. If it should be tested at all – and thus cost money, effort and patient-participation – a rigorous study should be designed and conducted not by apologists of the intervention but by more level-headed scientists.

In 2010, NICE recommended acupuncture for chronic low back pain (cLBP). Acupuncturists were of course delighted; the British Acupuncture Council, for instance, stated that they fully support NICE’s (National Institute for Health and Clinical Excellence) decision that acupuncture be made available on the NHS for chronic lower back pain. Traditional acupuncture has been used for over 2,000 years to alleviate back pain and British Acupuncture Council members have for many many years been successfully treating patients for this condition either in private practice or working within the NHS. In effect, therefore, these new guidelines are a rubber stamp of the positive work already being undertaken as well as an endorsement of the wealth of research evidence now available in this area.

More critical experts, however, tended to be surprised about this move and doubted that the evidence was strong enough for a positive recommendation. Now a brand-new meta-analysis sheds more light on this important issue.

Its aim was to determine the effectiveness of acupuncture as a therapy for cLBP. The authors found 13 RCTs which matched their inclusion criteria. Their results show that, compared with no treatment, acupuncture achieved better outcomes in terms of pain relief, disability recovery and better quality of life. These effects were, however, not observed when real acupuncture was compared to sham acupuncture. Acupuncture achieved better outcomes when compared with other treatments. No publication bias was detected.

The authors conclude that acupuncture is an effective treatment for chronic low back pain, but this effect is likely to be produced by the nonspecific effects of manipulation.

In plain English, this means that the effects of acupuncture on cLBP are most likely due to placebo. Should NICE be recommending placebo-treatments and have the tax payer foot the bill? I think I can leave it to my readers to answer this question.

Tai Chi, as we know it in the West, is said to promote the smooth flow of “energy” throughout the body by performing postures, slow meditative movements and controlled breathing. Tai Chi is also supposed to help increasing flexibility, suppleness, balance and coordination. According to enthusiasts, the smooth, gentle movements of Tai Chi aid relaxation and help to keep the mind calm and focused.

Tai Chi has become popular in Western countries and is being considered for a surprisingly wide range of conditions. The patient/consumer is taught to perform postures, slow meditative movements and controlled breathing. The concepts underlying Tai Chi are strange, but that does not necessarily mean that the treatment is not effective for certain illnesses or symptoms.

There has been a surprising amount of research in this area, and some studies have generated encouraging results. A recent study which is unfortunately not available electronically ( Wu, WF; Muheremu, A; Chen, CH; Liu, WG; Sun, L. Effectiveness of Tai Chi Practice for Non-Specific Chronic Low Back Pain on Retired Athletes: A Randomized Controlled Study. JOURNAL OF MUSCULOSKELETAL PAIN 2013, 21:1, p.37-45) tested the effectiveness of Tai Chi for chronic back pain. Specifically, the researchers wanted to determine whether regular Tai Chi practice is superior to other means of sports rehabilitation in relieving non-specific chronic low back pain [LBP] in a younger population. They randomized 320 former athletes suffering from chronic LBP into a treatment [tai chi practice] and several control groups [regular sessions with swimming, backward walking or jogging, or no such interventions]. At the beginning, middle, and end of a six-month intervention, patients from all groups completed questionnaires assessing the intensity of LBP; in addition, a physical examination was conducted.

After 3 and 6 months, no statistically significant difference in the intensity of LBP was demonstrated between the Tai Chi and swimming. However, significant differences were demonstrated between the Tai Chi and backward walking, jogging, and no exercise groups.

The authors’ concluded that “Tai chi has better efficacy than certain other sports on the treatment of non-specific chronic LBP.”

This is only the second RCT of Tai chi for back pain. The first such study consisted of 160 volunteers between ages 18 and 70 years with persistent nonspecific low back pain. The experimental group (n = 80) had 18 Tai Chi sessions over a 10-week period. The waitlist control group continued with their usual health care. Bothersomeness of symptoms was the primary outcome, and secondary outcomes included pain intensity and pain-related disability. Tai Chi reduced bothersomeness of back symptoms by 1.7 points on a 0-10 scale, reduced pain intensity by 1.3 points on a 0-10 scale, and improved self-report disability by 2.6 points on the 0-24 Roland-Morris Disability Questionnaire scale. The authors of this RCT concluded that a 10-week Tai Chi program improved pain and disability outcomes and can be considered a safe and effective intervention for those experiencing long-term low back pain symptoms.

My own team have conducted their fair share of Tai Chi research. Specifically,we have published several systematic reviews of Tai Chi as an adjunctive or supportive treatment of various conditions, and the conclusions (in italics) have been mixed.

DIABETES: The existing evidence does not suggest that tai chi is an effective therapy for type 2 diabetes.

HYPERTENSION: The evidence for tai chi in reducing blood pressure in the elderly individuals is limited.

BREAST CANCER: the existing trial evidence does not show convincingly that tai chi is effective for supportive breast cancer care.

IMPROVEMENT OF AEROBIC EXCERCISE CAPACITY: the existing evidence does not suggest that regular tai chi is an effective way of increasing aerobic capacity.

PARKINSON’S DISEASE: the evidence is insufficient to suggest tai chi is an effective intervention for Parkinson’s Disease.

OSTEOPOROSIS: The evidence for tai chi in the prevention or treatment of osteoporosis is not convincing.

OSTEOARTHRITIS: there is some encouraging evidence suggesting that tai chi may be effective for pain control in patients with knee OA.

RHEUMATOID ARTHRITIS: Collectively this evidence is not convincing enough to suggest that tai chi is an effective treatment for RA.

Finally, an overview over all systematic reviews of Tai Chi suggested that the only area where the evidence is convincing is the prevention of falls in the elderly.

I think, this indicates that we should not pin our hopes too high as to the therapeutic value of Tai Chi. In particular, for back pain, the evidence might be optimistically judged as encouraging, but it is by no means convincing; the effect size seems to be small and two studies are not enough to issue general recommendations. On the other hand, considering that there is so little to offer to back pain patients, I concede that this is an area that should be studied further. Meanwhile, one could argue that Tai Chi can be fun and is devoid of risks – so, why not give it a try?

According to the UK General Osteopathic Council, osteopathy is a system of diagnosis and treatment for a wide range of medical conditions.  It works with the structure and function of the body, and is based on the principle that the well-being of an individual depends on the skeleton, muscles, ligaments and connective tissues functioning smoothly together.

To an osteopath, for your body to work well, its structure must also work well.  So osteopaths work to restore your body to a state of balance, where possible without the use of drugs or surgery.  Osteopaths use touch, physical manipulation, stretching and massage to increase the mobility of joints, to relieve muscle tension, to enhance the blood and nerve supply to tissues, and to help your body’s own healing mechanisms.  They may also provide advice on posture and exercise to aid recovery, promote health and prevent symptoms recurring.

In case this sounds a bit vague to you, and in case you wonder what this “wide range of conditions” might be, rest assured, you are not alone. So let’s try to be a little more concrete and clear up some of the confusion around this profession. There are two very different types of osteopaths: US osteopaths are virtually identical with conventionally trained physicians; their qualification is equivalent to those of medical practitioners and they can, for instance, specialise to become GPs or neurologists or surgeons etc. Elsewhere, osteopaths are non-medically qualified alternative practitioners. In the UK, they are regulated by statute, in other counties not. And as to the “wide range of conditions”, I am not aware of any disease or symptom for which the evidence is convincing.

Osteopaths most commonly treat patients suffering from Chronic Non-Specific Low Back Pain (CNSLBP) using a set of non-drug interventions, particularly manual therapies such as spinal mobilisation and manipulation. The question is how well are these techniques supported by reliable evidence. To answer it, we must not cherry-pick our evidence but we need to consider the totality of the reliable studies; in other words, we need an up-to-date systematic review. Such an assessment of clinical research into osteopathic intervention for CNSLBP was recently published by Australian experts.

A thorough search of the literature in multiple electronic databases was undertaken,  and all articles were included that reported clinical trials; had adult participants; tested the effectiveness and/or efficacy of osteopathic manual therapies applied by osteopaths, and had a study condition of CNSLBP. The quality of the trials was assessed using the Cochrane criteria. Initial searches located 809 papers, 772 of which were excluded on the basis of abstract alone. The remaining 37 papers were subjected to a detailed analysis of the full text, which resulted in 35 further articles being excluded. There were thus only two studies assessing the effectiveness of manual therapies applied by osteopaths in adult patients with CNSLBP. The results of one trial suggested  that the osteopathic intervention was similar in effect to a sham intervention, and the other implies equivalence of effect between osteopathic intervention, exercise and physiotherapy.

I guess, this comes as a bit of a surprise to many consumers who have been told over and over again by osteopaths and their supporters that the evidence is sound. Personally, I am not at all surprised because, two years ago, we published a similar review, albeit with a wider spectrum of conditions, namely any type of musculoskeletal pain. We managed to include a total of 16 RCTs. Five of them suggested that osteopathy leads to a significantly stronger reduction of musculoskeletal pain than a range of control interventions. However, 11 RCTs indicated that osteopathy, compared to controls, generates no change in musculoskeletal pain. At the time, we felt that these data fail to produce compelling evidence for the effectiveness of osteopathy as a treatment of musculoskeletal pain.

This lack of convincing evidence is in sharp contrast to the image of osteopaths as back pain specialists. The UK General Osteopathic council, for instance, sates that Osteopaths’ patients include the young, older people, manual workers, office professionals, pregnant women, children and sports people. Patients seek treatment for a wide variety of conditions, including back pain…In addition, thousands of websites try to convince the consumer that osteopathy is a well-proven therapy for chronic low back pain – not to mention the many other conditions for which the evidence is even less sound.

As so often in alternative medicine, these claims seem to be based more on wishful thinking than on reliable evidence. And as so often, the victims of bogus claims are the consumers who are being misled into making wrong therapeutic decisions, wasting money, and delaying recovery from illness.

Some national and international guidelines advise physicians to use spinal manipulation for patients suffering from acute (and chronic) low back pain. Many experts have been concerned about the validity of this advice. Now an up-date of the Cochrane review on this subject seems to provide clarity on this rather important matter.

Its aim was to assess the effectiveness of spinal manipulative therapy (SMT) as a treatment of acute low back pain. Randomized controlled trials (RCTs) testing manipulation/mobilization in adults with  low back pain of less than 6-weeks duration were included. The primary outcome measures were pain, functional status and perceived recovery. Secondary endpoints were return-to-work and quality of life. Two authors independently conducted the study selection, risk of bias assessment and data extraction. The effects were examined for SMT versus  inert interventions, sham SMT,  other interventions, and for SMT as an adjunct to other forms of treatment.

The researchers identified 20 RCTs with a total number of 2674 participants, 12 (60%) RCTs had not been included in the previous version of this review. Only 6 of the 20 studies had a low risk of bias. For pain and functional status, there was low- to very low-quality evidence suggesting no difference in effectiveness of SMT compared with inert interventions, sham SMT or as adjunct therapy. There was varying quality of evidence suggesting no difference in effectiveness of SMT compared with other interventions. Data were sparse for recovery, return-to-work, quality of life, and costs of care.

The authors draw the following conclusion: “SMT is no more effective for acute low back pain than inert interventions, sham SMT or as adjunct therapy. SMT also seems to be no better than other recommended therapies. Our evaluation is limited by the few numbers of studies; therefore, future research is likely to have an important impact on these estimates. Future RCTs should examine specific subgroups and include an economic evaluation.”

In other words, guidelines that recommend SMT for acute low back pain are not based on the current best evidence. But perhaps the situation is different for chronic low back pain? The current Cochrane review of 26 RCTs is equally negative: “High quality evidence suggests that there is no clinically relevant difference between SMT and other interventions for reducing pain and improving function in patients with chronic low-back pain. Determining cost-effectiveness of care has high priority. Further research is likely to have an important impact on our confidence in the estimate of effect in relation to inert interventions and sham SMT, and data related to recovery.”

This clearly begs the question why many of the current guidelines seem to mislead us. I am not sure I know the answer to this one; however I suspect that the panels writing the guidelines might have been dominated by chiropractors and osteopaths or their supporters who have not exactly made a name for themselves for being impartial. Whatever the reason, I think it is time for a re-think and for up-dating guidelines which are out of date and misleading.

Similarly, it might be time to question for what conditions chiropractors and osteopaths, the two professions who use spinal manipulation/mobilisation most, do actually offer anything of real value at all. Back pain and SMT are clearly their domains; if it turns out that SMT is not evidence-based for back pain, what is left? There is no good evidence for anything else, as far as I can see. To make matters worse, there are quite undeniable risks associated with SMT. The conclusion of such considerations is, I fear, obvious: the value of and need for these two professions should be re-assessed.

Chiropractors have become (in)famous for making claims which  contradict the known facts. One claim that we find with unfailing regularity is that “regular chiropractic treatments will improve your quality of life“. There are uncounted websites advertising this notion, and most books on the subject promote it as well, some are even entirely dedicated to the theme. Here is a quote from a typical quote from one site chosen at random: “Quality of life chiropractic care is the pinnacle of chiropractic care within the chiropractic paradigm.  It does not solely rely on pain or postural findings, but rather on how a persons life can be positively influenced through regular adjustments… A series of regular adjustments is programmed and continual advice on life improvement is given.  It is designed as a long term approach and gains its strength from the regularity of its delivery.”

Given the ubiquitous nature of such claims, and given the fact that many chiropractic clients have back problems which reduce their quality of life, and given that back pain is just about the only condition for which chiropractors might have something to offer, it seems relevant to ask the following question: what is the evidence that chiropractic interventions affect the quality of life of back pain sufferers?

Some time ago, an Italian randomised clinical trial compared chiropractic spinal manipulations with sham-manipulations in patients affected by back pain and sciatica. Its results were disappointing and showed “no significant differences in quality of life and psychosocial scores.” But this is just one (potentially cherry-picked) study, I hear my chiropractic friends object. What we quite clearly need, is someone who takes the trouble to evaluate the totality of the available evidence.

Recently, Australian researchers published a review which did just that. Its authors conducted thorough literature searches to find all relevant studies on the subject. Of the 1,165 articles they located, 12 investigations of varying quality were retained, representing 6 studies, 4 randomised clinical trial and two observational studies. There was a high degree of inconsistency and lack of standardisation in measurement instruments and outcome measures. Three studies reported reduced use of additional treatments as a positive outcome; two studies reported a positive effect of chiropractic interventions on pain, and two studies reported a positive effect on disability. The 6 studies reviewed concentrated on the impact of chiropractic care on physical health and disability, rather than the wider holistic view which was the focus of the review. On the basis of this evidence, the authors conclude that “it is difficult… to defend any conclusion about the impact of chiropractic intervention on the quality of life, lifestyle, health and economic impact on chiropractic patients presenting with back pain.”


What should we make of all this? I don’t know about you, but I fear the notion that chiropractic improves the quality of life of back pain patients is just another of these many bogus assumptions which chiropractors across the globe seem to promote, advertise and make a living from.

As I have mentioned before, I like positive news as much as the next person. Therefore, I am constantly on the look-out for recently published, sound evidence suggesting that  some form of alternative medicine is effective and safe for this or that condition. This new systematic review fits that description, I am pleased to report.

Its authors evaluated the effectiveness of massage therapy (MT) for neck and shoulder pain. Their extensive literature searches identified 12 high-quality studies. The meta-analyses showed significant effects of MT for neck pain and shoulder pain compared to inactive therapies. MT did not yield better effects for neck pain or shoulder pain than other active therapies administered to the control groups. Shoulder function was not significantly affected by MT. The authors concluded that “MT may provide immediate effects for neck and shoulder pain. However, MT does not show better effects on pain than other active therapies. No evidence suggests that MT is effective in functional status”.

Massage therapy is thus a promising treatment, particularly as this systematic review is by no means the only piece of encouraging evidence. It is not better than other effective treatments, but it is not associated with frequent or serious adverse effects. This means that the demonstrable benefits are likely to outweigh its risks; in other words, the risk benefit balance is positive. Regular readers of this blog will appreciate the importance of this point.

Massage is practiced by several professions: mostly, of course, by massage therapists, but occasionally also by nurses, osteopath, chiropractors etc. Chiropractors, in particular, have recently tried to make much – I think too much – of this fact. They tend to claim that, as they use treatments which are evidence-based, such as massage, chiropractic is an evidence-based profession. I think this is akin to surgeons claiming that all of surgery is evidence-based because surgeons use medications which effectively reduce post-operative pain. Chiropractors foremost employ spinal manipulation and surgeons foremost use surgery; if they want us to believe that their practice is evidence-based, they need to show us the evidence for their hall-mark interventions. In the case of surgery, the evidence is mostly established; in the case of chiropractic, it is mostly not.

Massage is backed by reasonably sound evidence not just for neck and shoulder pain but for a range of other conditions as well. WHAT DO WE CALL AN ALTERNATIVE MEDICINE THAT WORKS? WE CALL IT MEDICINE!

So why is massage not a mainstream therapy? The answer is simple: in many countries, massage therapy has long been considered to be entirely conventional. Twenty years ago, I was chair of rehabilitation medicine at the university of Vienna. Amongst my staff, there always were about 5-8 full time massage therapists and nobody thought this to be unusual in any way. Similarly, in Germany, massage is entirely conventional.

Perhaps it is time that the English-speaking countries catch up with Europe when it comes to massage therapy and the evidence that supports it?

Acupuncture remains a highly controversial treatment: its mechanism of action is less than clear and the clinical results are equally unconvincing. Of course, one ought to differentiate between different conditions; the notion that acupuncture is a panacea is most certainly nonsense.

In many countries, acupuncture is being employed mostly in the management of pain, and it is in this area where the evidence is perhaps most encouraging. Yet, even here the evidence from the most rigorous clinical trials seems to suggest that much, if not all of the effects of acupuncture might be due to placebo.

Moreover, we ought to be careful with generalisations and ask what type of pain? One very specific pain is that caused by aromatase inhibitors (AI), a medication frequently prescribed to women suffering from breast cancer. Around 50 % of these patients complain of AI-associated musculoskeletal symptoms (AIMSS) and 15 % discontinue treatment because of these complaints. So, can acupuncture help these women?

A recent randomised, sham-controlled trial tested whether acupuncture improves AIMSS. Postmenopausal women with early stage breast cancer, experiencing AIMSS were randomized to eight weekly real or sham acupuncture sessions. The investigators evaluated changes in the Health Assessment Questionnaire Disability Index (HAQ-DI) and pain visual analog scale (VAS). Serum estradiol, β-endorphin, and proinflammatory cytokine concentrations were also measured pre and post-intervention. In total, 51 women were enrolled of whom 47 were evaluable (23 randomized to real and 24 to sham acupuncture).

Baseline characteristics turned out to be balanced between groups with the exception of a higher HAQ-DI score in the real acupuncture group. The results failed to show a statistically significant difference in reduction of HAQ-DI or VAS between the two groups. Following eight weekly treatments, a significant reduction of IL-17 was noted in both groups. No significant modulation was seen in estradiol, β-endorphin, or other proinflammatory cytokine concentrations in either group. No difference in AIMSS changes between real and sham acupuncture was seen.

Even though this study was not large, it was rigorously executed and well-reported. As many acupuncturists claim that their treatment alleviates pain and as many women suffering from AM-induced pain experience benefit, acupuncture advocates will nevertheless claim that the findings of this study are wrong, misleading or irrelevant. The often remarkable discrepancy between experience and evidence will again be the subject of intense discussions. How can a tiny trial overturn the experience of so many?

The answer is: VERY EASILY! In fact, the simplest explanation is that both are correct. The trial was well-done and its findings are thus likely to be true. The experience of patients is equally true – yet it relies not on the effects of acupuncture per se, but on the context in which it is given. In simple language, the effects patients experience after acupuncture are due to a placebo-response.

This is the only simple explanation which tallies with both the evidence and the experience. Once we think about it carefully, we realise that acupuncture is highly placebo-genic:

It is exotic.

It is invasive.

It is slightly painful.

It involves time with a therapist.

It involves touch.

If anyone had the task to develop a treatment that maximises placebo-effects, he could not come up with a better intervention!

Ahhh, will acupuncture-fans say, this means that acupuncture is a helpful therapy. I don’t care how it works, as long as it does help. Did we not just cover this issues in some detail? Indeed we did –  and I do not feel like re-visiting the three fallacies which underpin this sentence again.

Musculoskeletal and rheumatic conditions, often just called “arthritis” by lay people, bring more patients to alternative practitioners than any other type of disease. It is therefore particularly important to know whether alternative medicines (AMs) demonstrably generate more good than harm for such patients. Most alternative practitioners, of course, firmly believe in what they are doing. But what does the reliable evidence show?

To find out, ‘Arthritis Research UK’ has sponsored a massive project  lasting several years to review the literature and critically evaluate the trial data. They convened a panel of experts (I was one of them) to evaluate all the clinical trials that are available in 4 specific clinical areas. The results for those forms of AM that are to be taken by mouth or applied topically have been published some time ago, now the report, especially written for lay people, on those treatments that are practitioner-based has been published. It covers the following 25 modalities: 


Alexander technique


Autogenic training


Chiropractic (spinal manipulation)

Copper bracelets

Craniosacral therapy

Crystal healing


Kinesiology (applied kinesiology)

Healing therapies



Magnet therapy (static magnets)



Music therapy

Osteopathy (spinal manipulation)

Qigong (internal qigong)


Relaxation therapy


Tai chi


Our findings are somewhat disappointing: only very few treatments were shown to be effective.

In the case of rheumatoid arthritis, 24 trials were included with a total of 1,500 patients. The totality of this evidence failed to provide convincing evidence that any form of AM is effective for this particular condition.

For osteoarthritis, 53 trials with a total of ~6,000 patients were available. They showed reasonably sound evidence only for two treatments: Tai chi and acupuncture.

Fifty trials were included with a total of ~3,000 patients suffering from fibromyalgia. The results provided weak evidence for Tai chi and relaxation-therapies, as well as more conclusive evidence for acupuncture and massage therapy.

Low back pain had attracted more research than any of the other diseases: 75 trials with ~11,600 patients. The evidence for Alexander Technique, osteopathy and relaxation therapies was promising by not ultimately convincing, and reasonably good evidence in support of yoga and acupuncture was also found.

The majority of the experts felt that the therapies in question did not frequently cause harm, but there were two important exceptions: osteopathy and chiropractic. For both, the report noted the existence of frequent yet mild, as well as serious but rare adverse effects.

As virtually all osteopaths and chiropractors earn their living by treating patients with musculoskeletal problems, the report comes as an embarrassment for these two professions. In particular, our conclusions about chiropractic were quite clear:

There are serious doubts as to whether chiropractic works for the conditions considered here: the trial evidence suggests that it’s not effective in the treatment of fibromyalgia and there’s only little evidence that it’s effective in osteoarthritis or chronic low back pain. There’s currently no evidence for rheumatoid arthritis.

Our point that chiropractic is not demonstrably effective for chronic back pain deserves some further comment, I think. It seems to be in contradiction to the guideline by NICE, as chiropractors will surely be quick to point out. How can this be?

One explanation is that, since the NICE-guidelines were drawn up, new evidence has emerged which was not positive. The recent Cochrane review, for instance, concludes that spinal manipulation “is no more effective for acute low-back pain than inert interventions, sham SMT or as adjunct therapy”

Another explanation could be that the experts on the panel writing the NICE-guideline were less than impartial towards chiropractic and thus arrived at false-positive or over-optimistic conclusions.

Chiropractors might say that my presence on the ‘Arthritis Research’-panel suggests that we were biased against chiropractic. If anything, the opposite is true: firstly, I am not even aware of having a bias against chiropractic, and no chiropractor has ever demonstrated otherwise; all I ever aim at( in my scientific publications) is to produce fair, unbiased but critical assessments of the existing evidence. Secondly, I was only one of a total of 9 panel members. As the following list shows, the panel included three experts in AM, and most sceptics would probably categorise two of them (Lewith and MacPherson) as being clearly pro-AM:

Professor Michael Doherty – professor of rheumatology, University of Nottingham

Professor Edzard Ernst – emeritus professor of complementary medicine, Peninsula Medical School

Margaret Fisken – patient representative, Aberdeenshire

Dr Gareth Jones (project lead) – senior lecturer in epidemiology, University of Aberdeen

Professor George Lewith – professor of health research, University of Southampton

Dr Hugh MacPherson – senior research fellow in health sciences, University of York

Professor Gary Macfarlane (chair of committee) professor of epidemiology, University of Aberdeen

Professor Julius Sim – professor of health care research, Keele University

Jane Tadman – representative from Arthritis Research UK, Chesterfield

What can we conclude from all that? I think it is safe to say that the evidence for practitioner-based AMs as a treatment of the 4 named conditions is disappointing. In particular, chiropractic is not a demonstrably effective therapy for any of them. This, of course begs the question, for what condition is chiropractic proven to work! I am not aware of any, are you?
