THE HINKLEY TIMES is quickly becoming my favourite newspaper. Yesterday they published an article about my old friend Tredinnick. I cannot resist showing you a few excerpts from it:
START OF EXCERPTS
Alternative therapy advocate, David Tredinnick has called for greater self reliance as a way of reducing pressures on the NHS. Speaking on the BBC’s regional Sunday Politics Show he suggested people should take more responsibility for their own health, rather than relying on struggling services. He highlighted homeopathy as a way of treating ailments at home and said self-help could cut unnecessary trips to the GP. He also said people could avoid illness by not being overweight and taking exercise…During debate on the show about the current ‘crisis’ in health and social care he said: “There are systems such as homeopathic remedies. Try it yourself before going to the doctor.”
Mr Tredinnick has always stood by his personal preferences for traditional therapies despite others disparaging his views. His recent remarks have sparked a response from Lib Dem Parliamentary spokesman Michael Mullaney. He said in the wake of the NHS facing cuts and closures, Mr Tredinnick was yet again showing he was out of touch. He added: “It’s dangerous for Mr Tredinnick, who is not properly medically trained, to use his platform as an MP to tell ill people to treat themselves with homeopathy, a treatment for which there is no medical proof that it works. He should stop talking about his quack theories and do his job representing the people of Hinckley and Bosworth, or otherwise he should resign as MP for he is totally failing to do his job of representing local people.”
END OF EXCERPTS
Yes, there is no doubt in my mind: if the public would ever take Tredinnick seriously when he talks about quackery, our health would be in danger. Therefore, it must be seen as most fortunate that hardly anyone does take him seriously. And here are a few reasons why this is so:
Personally, I would very much regret if he resigned – there would be so much less to laugh about in the realm of alternative medicine!
We all know that alternative medicine is currently popular, and much of the evidence suggested that this is mostly because mostly people in the midst of their lives are using it. This may be so, but it is about to change; it stands to reason that these ‘baby boomers’ are getting older, and therefore the typical user of alternative medicine is or will soon be an elderly person. In addition, the ‘oldies’ (I am one of them) are likely to be multi-morbid and therefore have more reason to try everything that is on offer.
Not convinced? But that is roughly is what this website seems to suggest:

Geriatric population is more susceptible to chronic diseases such as heart problems, joint disorders and others. Therefore, this population group needs regular use of the medicines to prevent the disease conditions. The use of complementary and alternative medicines is increasing among the geriatric population globally due to the fact that CAMs decreases the risk of adverse reactions and drug interactions.
Complementary and alternative medicines include products such as dietary medicine and herbal medicine products. These medicines can be used for the management of both communicable (i.e. tuberculosis, hantavirus and others) and non communicable diseases (i.e. chronic kidney disease, cardiovascular and others) in geriatric population. These medicines (i.e. CAM) treat the patients by healing therapies which is not based on principles of conventional medicine.
Geographically, North America is considered as the largest market of geriatric complementary and alternative medicines owing to high use of CAMs in this region. For example, Health and Retirement Study conducted one survey which concluded that around 85% of the geriatric population in North America reported the use of complementary and alternative medicines. Thus, high use of CAM modalities will establish healthy platform to develop the growth of geriatric complementary and alternative medicines market.
Europe is the second largest market of geriatric complementary and alternative medicines. The growth is mainly attributed to the increasing aging population coupled with rising use of complementary and alternative medicines in Europe. According to European Commission (Eurostat) report published in 2013, around 17.8% of the European population were aged 65 years and above. The organization has also stated that aging population is expected to increase at high rate in coming year in Europe. In addition, Asia-Pacific is the emerging market for geriatric complementary and alternative medicines market because of rising interest of key companies to expand their presence in Asia Pacific.
Key companies operating in the market for geriatric complementary and alternative medicines include Geriatric & Medical Companies, Inc., Merck Sharp & Dohme Corporation. Geri-Care pharmaceuticals, UAS Laboratories.

I know, this text includes several glaring errors. But the main claim that alternative medicine is fast becoming a thing for the elderly might well be true. This, of course, has implications for marketing, research, etc. For us on this blog it means that we need to find better ways to get through to people who are no spring chickens any longer.
The elderly have special needs and can be vulnerable in several ways. When they are ill, they need efficacious treatments. By and large, this excludes alternative therapies. The elderly may also be more susceptible to the risks of alternative medicine. Moreover, they are often not that affluent and might need to watch their expenses. Making them spend large amounts of cash on treatments that are ineffective is therefore a particularly unethical.
I think that messages like these might convince some elderly people to stop putting unreasonable hope in, and wasting their time/money on bogus therapies. But I am very keen to hear from my readers about further ideas how to curb the boom of alternative medicine in this age group.
Chiropractors (and other alternative practitioners) tend to treat their patients for unnecessarily long periods of time. This, of course, costs money, and even if the treatment in question ever was indicated (which, according to the best evidence, is more than doubtful), this phenomenon would significantly inflate healthcare expenditure.
This sounds perfectly logical to me, but is there any evidence for it? Yes, there is!
The WSJ recently reported that over 80% of the money that Medicare paid to US chiropractors in 2013 went for medically unnecessary procedures. The federal insurance program for senior citizens spent roughly $359 million on unnecessary chiropractic care that year, a review by the Department of Health and Human Services’ Office of Inspector General (OIG) found.
The OIG report was based on a random sample of Medicare spending for 105 chiropractic services in 2013. It included bills submitted to CMS through June 2014. Medicare audit contractors reviewed medical records for patients to determine whether treatment was medically necessary. The OIG called on the Centers for Medicare and Medicaid Services (CMS) to tighten oversight of the payments, noting its analysis was one of several in recent years to find questionable Medicare spending on chiropractic care. “Unless CMS implements strong controls, it is likely to continue to make improper payments to chiropractors,” the OIG said.
Medicare should determine whether there should be a cut-off in visits, the OIG said. Medicare does not pay for “supportive” care, or maintenance therapy. Patients who received more than a dozen treatments are more likely to get medically unnecessary care, the OIG found, and all chiropractic care after the first 30 treatment sessions was unnecessary, the review found. However, a spokesperson for US chiropractors disagreed: “Every patient is different,” he said. “Some patients may require two visits; some may require more.”
I have repeatedly written about the fact that chiropractic is not nearly as cost-effective as chiropractors want us to believe (see for instance here and here). It seems that this evidence is being systematically ignored by them; in fact, the evidence gets in the way of their aim – which often is not to help patients but to maximise their cash-flow.
Since several years, there has been an increasingly vociferous movement within the chiropractic profession to obtain limited prescription rights, that is the right to prescribe drugs for musculoskeletal problems. A recent article by Canadian and Swiss chiropractors is an attempt to sum up the arguments for and against this notion. Here I have tried to distil the essence of the pros and contras into short sentences.
1) Arguments in favour of prescription rights for chiropractors
1.1 Such privileges would be in line with current evidence-based practice. Currently, most international guidelines recommend, alongside prescription medication, a course of manual therapy and/or exercise as well as education and reassurance as part of a multi-modal approach to managing various spine-related and other MSK conditions.
1.2 Limited medication prescription privileges would be consistent with chiropractors’ general experience and practice behaviour. Many clinicians tend to recommend OTC medications to their patients in practice.
1.3 A more comprehensive treatment approach offered by chiropractors could potentially lead to a reduction in healthcare costs by providing additional specialized health care options for the treatment of MSK conditions. Namely, if patients consult one central practitioner who can effectively address and provide a range of treatment modalities for MSK pain-related matters, the number of visits to providers might be reduced, thereby resulting in better resource allocation.
1.4 Limited medication prescription rights could lead to improved cultural authority for chiropractors and better integration within the healthcare system.
1.5 With these privileges, chiropractors could have a positive influence on public health. For instance, analgesics and NSAIDs are widely used and potentially misused by the general public, and users are often unaware of the potential side effects that such medication may cause.
2) Arguments against prescription rights for chiropractors
2.1 Chiropractors and their governing bodies would start reaching out to politicians and third-party payers to promote the benefits of making such changes to the existing healthcare system.
2.2 Additional research may be needed to better understand the consequences of such changes and provide leverage for discussions with healthcare stakeholders.
2.3 Existing healthcare legislation needs to be amended in order to regulate medication prescription by chiropractors.
2.4 There is a need to focus on the curriculum of chiropractors. Inadequate knowledge and competence can result in harm to patients; therefore, appropriate and robust continuing education and training would be an absolute requirement.
2.5 Another important issue to consider relates to the divisiveness around this topic within the profession. In fact, some have argued that the right to prescribe medication in chiropractic practice is the profession’s most divisive issue. Some have argued that further incorporation of prescription rights into the chiropractic scope of practice will negatively impact the distinct professional brand and identity of chiropractic.
2.6 Such privileges would increase chiropractors’ professional responsibilities. For example, if given limited prescriptive authority, chiropractors would be required to recognize and monitor medication side effects in their patients.
2.7 Prior to medication prescription rights being incorporated into the chiropractic scope of practice worldwide, further discussions need to take place around the breadth of such privileges for the chiropractic profession.
In my view, some of these arguments are clearly spurious, particularly those in favour of prescription rights. Moreover, the list of arguments against this notion seems a little incomplete. Here are a few additional ones that came to my mind:
- Patients might be put at risk by chiropractors who are less than competent in prescribing medicines.
- More unnecessary NAISDs would be prescribed.
- The vast majority of the drugs in question is already available OTC.
- Healthcare costs would increase (just as plausible as the opposite argument made above, I think).
- Prescribing rights would give more legitimacy to a profession that arguably does not deserve it.
- Chiropractors would then continue their lobby work and soon demand the prescription rights to be extended to other classes of drugs.
I am sure there are plenty of further arguments both pro and contra – and I would be keen to hear them; so please post yours in the comments section below.
Several investigations have suggested that chiropractic care can be cost-effective. A recent review of 25 studies, for instance, concluded that cost comparison studies suggest that health care costs were generally lower among patients whose spine pain was managed with chiropractic care. However, its authors cautioned that the studies reviewed had many methodological limitations. Better research is needed to determine if these differences in health care costs were attributable to the type of HCP managing their care.
Better research might come from the US ‘Centers for Medicaid and Medicare Services’ (CMS); they conduced a two-year demonstration of expanded Medicare coverage for chiropractic services in the treatment of beneficiaries with neuromusculoskeletal (NMS) conditions affecting the back, limbs, neck, or head.
The demonstration was conducted in 2005–2007 in selected counties of Illinois, Iowa, and Virginia and the entire states of Maine and New Mexico. Medicare claims were compiled for the preceding year and two demonstration years for the demonstration areas and matched comparison areas. The impact of the demonstration was analyzed through multivariate regression analysis with a difference-in-difference framework.
Expanded coverage increased Medicare expenditures by $50 million or 28.5% in users of chiropractic services and by $114 million or 10.4% in all patients treated for NMS conditions in demonstration areas during the two-year period. Results varied widely among demonstration areas ranging from increased costs per user of $485 in Northern Illinois and Chicago counties to decreases in costs per user of $59 in New Mexico and $178 in Scott County, Iowa.
The authors concluded that the demonstration did not assess possible decreases in costs to other insurers, out-of-pocket payments by patients, the need for and costs of pain medications, or longer term clinical benefits such as avoidance of orthopedic surgical procedures beyond the two-year period of the demonstration. It is possible that other payers or beneficiaries saved money during the demonstration while costs to Medicare were increased.
In view of such results, I believe chiropractors should stop claiming that chiropractic care is cost-effective.
I have previously reported about the issue of homeopathy on the NHS in Liverpool here. Since then, the NHS Liverpool Clinical Commissioning Group (CCG) has conducted a consultation on whether to continue funding. Personally, I think such polls are a daft waste of resources.
I will explain in a moment; first read the (slightly shortened) summary:
In November 2015, NHS Liverpool CCG Governing Body stated a preference to decommission the homeopathy service and commenced the consultation exercise with the intent to ascertain how the public felt about it. This report was written by the Centre for Public Health, Liverpool John Moores University, and includes independent analysis of the consultation activities.
The consultation ran from 13th November – 22nd December 2015. The two main methods used were 1) a survey available online and in paper format. It was completed by 743 individual respondents and, of those who provided a valid postcode, 68% (323 individuals) lived within the Liverpool CCG area, 2) a small consultation event held on 4th December 2015 facilitated by Liverpool John Moores University. The event was attended by 29 individuals, the majority of whom were patients and staff from the Liverpool Medical Homeopathic Service. Eighteen of the participants at this event resided in Liverpool.
Two thirds of survey respondents (66%; 380 respondents) said they would never use homeopathy services in the future. The reasons for this included the lack of evidence and scientific basis of homeopathy; negative personal experiences of homeopathy; and believing it was an inappropriate use of NHS funding. Those who would be likely to use it in the future (28%) felt they wanted to be able to choose an alternative to conventional medicine; felt it was value for money for the NHS; appreciated the time, care and holistic consultation; and discussed their own positive experiences. Sixty six per cent of survey respondents (111) who had used homeopathy in the past reported an excellent or good experience. Those who reported a positive experience (66%) felt that homeopathy had improved their health where conventional medicine had not, and participants valued that the homeopathic practitioner had treated their emotional as well as their physical needs. Those who reported a below average or poor experience (31%) felt homeopathy had not improved their medical condition and some felt they had been misled and had not been told the remedy contained no active ingredients.
At the consultation event, the majority of the 29 participants were homeopathy service users and they described a positive experience of homeopathy and the ability to choose ‘holistic’ and non-pharmaceutical treatment. Participants also questioned what services they could use if they were unable to access homeopathy on the NHS and were concerned and angry about the service potentially being decommissioned. A small number of participants at this event agreed with the view that there is a lack of evidence regarding efficacy and felt it was an inappropriate use of NHS funds that would be better spent on other, more effective services.
Of the survey respondents, 73% (541 individuals) chose the option to stop funding all homeopathy services; when including only Liverpool residents in the analysis this decreased to 64%. Twenty three per cent of survey respondents (170 individuals) wanted to continue to fund homeopathy services in Liverpool (either at current levels or to increase the budget); when only including Liverpool residents this proportion increased slightly to 30%. At the end of the consultation event the participants in the room (29 individuals) were asked to vote on their preferred funding option; twenty two participants (76%) wanted to continue the service and increase the maximum funding limit; three participants (14%) wanted to stay with the current situation and three participants (10%) wanted to stop funding the service.
There was some tension in what those in the consultation saw as acceptable and appropriate evidence about the effectiveness of homeopathy. Many participants in the survey and at the event reported their positive experience or anecdotal evidence as “proof” that homeopathy is effective. There was a low understanding about how scientific research is conducted or evaluated. The NHS try to base funding decisions on rigorous, high-quality, unbiased, peer-reviewed research, however, the CCG is required to account of all evidence, including patient experience, when funding or discontinuing services.
Across the survey and the consultation event there was some confusion about what types of treatment come under the heading of “homeopathy”, with participants making reference to a range of herbal remedies and supplements. Iscador (a mistletoe extract) may be, in some cases, provided as a complementary treatment for patients with cancer, however, this is not a homeopathic remedy. There was also discussion (in the event and in the survey responses) about other herbal remedies and supplements.
END OF SUMMARY
So, why do I not think highly about exercises of this kind?
In general, surveys are tricky and often very dodgy research tools. Particularly in alternative medicine, they are as popular as they are useless. The potential problems arise from the way the methodology is often applied. For instance, sampling is crucial. If, like in the present case, no rigorous sampling techniques are applied, the results will inevitably be unreliable in reflecting the views of a population.
The findings of the survey above could easily be little more than a reflection of which camp had a better PR. Homeopaths usually are very good on such occasions at persuading others for homeopathy. In this case, the results show that, despite their best efforts, the overall vote was not positive for homeopathy. What we don’t know is whether this is a reflection on the ‘will of the people’. It could be that the public is much more against funding nonsense than this poll suggests.
I would also argue that letting people vote about the availability of medical interventions is nonsensical. The value of healthcare technologies is not determined by such ‘beauty contests’; the value depends on the scientific evidence, and that is not readily evaluated by non-experts. Imagine: next we might vote for or against bone-marrow transplants; who has the expertise to cast such a vote?
Oh yes, and the ‘small consultation’ – what was that supposed to be. Probably just an exercise in political correctness. Nobody in their right mind can have expected any meaningful insight coming from it.
Finally, I dispute that ‘patients’ experience’ is the same as ‘evidence’, as the summary above seems to claim. This is just nonsense. evidence is something entirely different from experience.
But politicians will disregard all this. They will say ‘the public has decided’ and will stop funding homeopathy on the NHS in Liverpool. More by coincidence than by design, this survey went into the right direction. Now one can only hope that the rest of the country will follow suit – on evidence, not on dodgy pseudo-evidence from surveys.
Now, here is a surprise, at least for me it was one: I just came across a website [url deleted by Admin as potential phishing site] claiming that the estimated value of this blog is $21,928.77.
How on earth do they calculate this?
What does it mean?
How can you put a monetary value on a blog like mine?
I have to admit, I fail to know the answers to any of these questions. What I do know, however, is that, over the last few years, many complete strangers have assured me that my blog is ‘invaluable’. And comments like these are for me the sole reason for writing it.
If I did it for money, I would need quite a bit more than the above sum. When, a few years ago, I wrote a regular column and later blog for the Guardian, they paid me £ 250 for each article [if I remember correctly]. So, multiply the well over 500 posts on my blog by £ 250, and you arrive at an approximate value for it…something around £ 150 000.
Yes, I know, this is not realistic, in fact, it is barmy!
And therefore I prefer to attribute no monetary value to my blog and receive zero funds from anyone for my work here. People who occasionally tell me that it is invaluable is plenty of reward for me!
A recent article in the LIVERPOOL ECHO caught my eye. It is about the possibility that the NHS in Liverpool might stop funding their homeopathy service . Maybe I should read the LIVERPOOL ECHO more often, because the short article is most revealing.
It first cites the chairman of the local NHS Clinical Commissioning Group, Dr Nadim Fazlani saying that “There is little evidence that homeopathy has a clinical benefit so, as a governing body, our preferred option would be to stop commissioning this service. However, it is important that the people have an opportunity to provide their views before a decision is made.”
I would like to mention, however, that health care is not a beauty contest or a supermarket shelve. We don’t have popular votes for bone marrow transplants or bypass surgery either. Why? Not because we don’t believe in democracy but because the general public cannot possibly understand medicine well enough. This is why we send some of our kids to medical school and other institutions to help us comprehend and eventually take responsible decisions for us. It is, I think, an ethical imperative to base important health care decisions of this nature on the best evidence and expertise, and it seems foolish to expect the public to have either.
Then the article in the LIVERPOOL ECHO quotes a statement of the Liverpool homeopathy service which is run by GPs Dr Hugh Nielsen and Dr Sue de Lacy: “The patients we see generally have long-standing, complex conditions that are often difficult to treat with conventional medicine. Yet regular audits of our clinic show a very high level of patient satisfaction, with patients consistently reporting an improvement in their health. As experienced doctors trained in homeopathy we see it working every day and that is why we believe Liverpool CCG – and more importantly the patients the CCG serves – is getting excellent value for the relatively small amount of funding the service receives.”
I find this interesting, not least because the arguments used by these two GPs are, in my view, miles better than those we have seen on this blog recently by Christian Boiron, Dana Ullman, Dr Michael Dixon or the Queen’s homeopath Dr Fisher all put together. At least they do not contain blatant lies!
This does not mean, however, that the arguments of the two homeopaths from Liverpool are convincing. They are not – for the following 4 reasons:
- True, long-standing, complex conditions are often difficult to treat with conventional medicine. But if they are difficult to treat with real medicine, they surely are even more difficult to treat with fake medicine.
- I have no problem believing that their audits show high level of patient satisfaction, with patients consistently reporting an improvement in their health. But we need to be quite clear that these effects are not brought about by the homeopathic remedies which contain zero active ingredients. They are due to the compassion shown by these homeopath. If they prescribed real medicine in addition to providing compassion, their results would in all likelihood be even better.
- It is also true that an experienced doctor trained in homeopathy will see it working every day. But the ‘it’ refers not to the remedy, it relates to the compassion – and to convey compassion, we do not need bogus treatments.
- It is a little misleading to claim that homeopathy is ‘excellent value’. The remedies contain nothing but lactose, and £ 5-10 for a gram or two of lactose is jolly expensive! So, the remedies are over-priced placebos, and the consultations might be good value.
Despite these counter-arguments, I must congratulate these two GPs from Liverpool: they seem to be so much more honest and intelligent than the defenders of homeopathy mentioned above.
The notion that the use homeopathy instead of real medicine might save money (heavily promoted by homeopaths and their followers, often to influence health politics) has always struck me as being utterly bizarre: without effectiveness, it is hard to imagine cost-effectiveness. Yet the Smallwood report (in)famously claimed that the NHS would save lots of money, if GPs were to use more homeopathy. At the time, I thought this was such a serious and dangerous error that I decided to do something about it. My objection to the flawed report might have prevented it being taken seriously by anyone with half a brain, but sadly it also cost me my job (the full story can be read here).
Later publications perpetuated the erroneous idea of homeopathy’s cost-effectiveness. For instance, an Italian analysis (published in the journal ‘Homeopathy’) concluded that homeopathic treatment for respiratory diseases (asthma, allergic complaints, Acute Recurrent Respiratory Infections) was associated with a significant reduction in the use and costs of conventional drugs. Costs for homeopathic therapy are significantly lower than those for conventional pharmacological therapy. Again, this paper was so badly flawed that, other than some homeopaths, nobody seemed to have taken the slightest notice of it.
Now a new article has been published on this very subject. The aim of this study was to compare the health care costs for patients using additional homeopathic treatment (homeopathy group) with the costs for those receiving usual care (control group).
Cost data provided by a large German statutory health insurance company were retrospectively analysed from the societal perspective (primary outcome) and from the statutory health insurance perspective. Patients in both groups were matched using a propensity score matching procedure based on socio-demographic variables as well as costs, number of hospital stays and sick leave days in the previous 12 months. Total cumulative costs over 18 months were compared between the groups with an analysis of covariance (adjusted for baseline costs) across diagnoses and for six specific diagnoses (depression, migraine, allergic rhinitis, asthma, atopic dermatitis, and headache).
Data from 44,550 patients (67.3% females) were available for analysis. From the societal perspective, total costs after 18 months were higher in the homeopathy group (adj. mean: EUR 7,207.72 [95% CI 7,001.14-7,414.29]) than in the control group (EUR 5,857.56 [5,650.98-6,064.13]; p<0.0001) with the largest differences between groups for productivity loss (homeopathy EUR 3,698.00 [3,586.48-3,809.53] vs. control EUR 3,092.84 [2,981.31-3,204.37]) and outpatient care costs (homeopathy EUR 1,088.25 [1,073.90-1,102.59] vs. control EUR 867.87 [853.52-882.21]). Group differences decreased over time. For all diagnoses, costs were higher in the homeopathy group than in the control group, although this difference was not always statistically significant.
The authors of this paper (who have a long track record of being pro-homeopathy) concluded that, compared with usual care, additional homeopathic treatment was associated with significantly higher costs. These analyses did not confirm previously observed cost savings resulting from the use of homeopathy in the health care system.
The next time someone does a (no doubt costly) cost-effectiveness analysis of an ineffective treatment, it would be good (and cost-effective) to remember: WITHOUT EFFECTIVENESS, THERE CAN BE NO COST-EFFECTIVENESS.
“So what? We all know that homeopathy is nonsense,” I hear some people argue, “at the same time, it is surely trivial. Let those nutters do what they want; at least it is not harmful!”

I THINK I CAN REST MY CASE.
We all know, I think, that chronic low back pain (CLBP) is common and causes significant suffering in individuals as well as cost to society. Many treatments are on offer but, as we have seen repeatedly on this blog, not one is convincingly effective and some, like chiropractic, is associated with considerable risks.
Enthusiasts claim that hypnotherapy works well, but too little is known about the minimum dose needed to produce meaningful benefits, the roles of home practice and hypnotizability on outcome, or the maintenance of treatment benefits beyond 3 months. A new trial was aimed at addressing these issues.
One hundred veterans with CLBP participated in a randomized, four parallel group study. The groups were (1) an eight-session self-hypnosis training intervention without audio recordings for home practice; (2) an eight-session self-hypnosis training intervention with recordings; (3) a two-session self-hypnosis training intervention with recordings and brief weekly reminder telephone calls; and (4) an eight-session active (biofeedback) control intervention.
Participants in all four groups reported significant pre- to post-treatment improvements in pain intensity, pain interference and sleep quality. The three hypnotherapy groups combined reported significantly more pain intensity reduction than the control group. There was no significant difference among the three hypnotherapy groups. Over half of the participants who received hypnotherapy reported clinically meaningful (≥30%) reductions in pain intensity, and they maintained these benefits for at least 6 months after treatment. Neither hypnotizability nor amount of home practice was associated significantly with treatment outcome.
The authors conclude that two sessions of self-hypnosis training with audio recordings for home practice may be as effective as eight sessions of hypnosis treatment. If replicated in other patient samples, the findings have important implications for the application of hypnosis treatment for chronic pain management.
Even though this trial has several important limitations, I do agree with the authors: these results would be worth an independent replication – not least because self-hypnosis is cheap and does not carry great risks. What would be interesting, in my view, are studies that compare several alternative LBP therapies (e.g. chiropractic, osteopathy, acupuncture, massage, various form of exercise and hypnotherapy) in terms of cost, risks, long-term effectiveness and patients’ preference. I somehow feel that the results of such comparative trials might overturn the often issued recommendations for spinal manipulation, i.e. chiropractic or osteopathy.
