The aim of this pragmatic study was “to investigate the effectiveness of acupuncture in addition to routine care in patients with allergic asthma compared to treatment with routine care alone.”
Patients with allergic asthma were included in a controlled trial and randomized to receive up to 15 acupuncture sessions over 3 months plus routine care, or to a control group receiving routine care alone. Patients who did not consent to randomization received acupuncture treatment for the first 3 months and were followed as a cohort. All trial patients were allowed to receive routine care in addition to study treatment. The primary endpoint was the asthma quality of life questionnaire (AQLQ, range: 1–7) at 3 months. Secondary endpoints included general health related to quality of life (Short-Form-36, SF-36, range 0–100). Outcome parameters were assessed at baseline and at 3 and 6 months.
A total of 1,445 patients were randomized and included in the analysis (184 patients randomized to acupuncture plus routine care and 173 to routine care alone, and 1,088 in the nonrandomized acupuncture plus routine care group). In the randomized part, acupuncture was associated with an improvement in the AQLQ score compared to the control group (difference acupuncture vs. control group 0.7 [95% confidence interval (CI) 0.5–1.0]) as well as in the physical component scale and the mental component scale of the SF-36 (physical: 2.5 [1.0–4.0]; mental 4.0 [2.1–6.0]) after 3 months. Treatment success was maintained throughout 6 months. Patients not consenting to randomization showed similar improvements as the randomized acupuncture group.
The authors concluded that in patients with allergic asthma, additional acupuncture treatment to routine care was associated with increased disease-specific and health-related quality of life compared to treatment with routine care alone.
We have been over this so many times (see for instance here, here and here) that I am almost a little embarrassed to explain it again: it is fairly easy to design an RCT such that it can only produce a positive result. The currently most popular way to achieve this aim in alternative medicine research is to do a ‘A+B versus B’ study, where A = the experimental treatment, and B = routine care. As A always amounts to more than nothing – in the above trial acupuncture would have placebo effects and the extra attention would also amount to something – A+B must always be more than B alone. The easiest way of thinking of this is to imagine that A and B are both finite amounts of money; everyone can understand that A+B must always be more than B!
Why then do acupuncture researchers not get the point? Are they that stupid? I happen to know some of the authors of the above paper personally, and I can assure you, they are not stupid!
I am afraid there is only one reason I can think of: they know perfectly well that such an RCT can only produce a positive finding, and precisely that is their reason for conducting such a study. In other words, they are not using science to test a hypothesis, they deliberately abuse it to promote their pet therapy or hypothesis.
As I stated above, it is fairly easy to design an RCT such that it can only produce a positive result. Yet, it is arguably also unethical, perhaps even fraudulent, to do this. In my view, such RCTs amount to pseudoscience and scientific misconduct.
The recent meta-analysis by Mathie et al for non-individualised homeopathy (recently discussed here) identified just 3 RCTs that were rated as ‘reliable evidence’. But just how rigorous are these ‘best’ studies? Let’s find out!
THE FIRST STUDY
The objective of the first trial was “to evaluate the efficacy of the non-hormonal treatment BRN-01 in reducing hot flashes in menopausal women.” Its design was that of a multicentre (35 centres in France), randomized, double-blind, placebo-controlled. One hundred and eight menopausal women, ≥50 years of age, were enrolled in the study. The eligibility criteria included menopause for <24 months and ≥5 hot flashes per day with a significant negative effect on the women’s professional and/or personal life. Treatment was either BRN-01 tablets, a registered homeopathic medicine [not registered in the UK] containing Actaea racemosa (4 centesimal dilutions [4CH]), Arnica montana (4CH), Glonoinum (4CH), Lachesis mutus (5CH), and Sanguinaria canadensis (4CH), or placebo tablets, prepared by Laboratoires Boiron according to European Pharmacopoeia standards [available OTC in France]. Oral treatment (2 to 4 tablets per day) was started on day 3 after study enrolment and was continued for 12 weeks. The main outcome measure was the hot flash score (HFS) compared before, during, and after treatment. Secondary outcome criteria were the quality of life (QoL) [measured using the Hot Flash Related Daily Interference Scale (HFRDIS)], severity of symptoms (measured using the Menopause Rating Scale), evolution of the mean dosage, and compliance. All adverse events (AEs) were recorded. One hundred and one women were included in the final analysis (intent-to-treat population: BRN-01, n = 50; placebo, n = 51). The global HFS over the 12 weeks, assessed as the area under the curve (AUC) adjusted for baseline values, was significantly lower in the BRN-01 group than in the placebo group (mean ± SD 88.2 ± 6.5 versus 107.2 ± 6.4; p = 0.0411). BRN-01 was well tolerated; the frequency of AEs was similar in the two treatment groups, and no serious AEs were attributable to BRN-01. The authors concluded that BRN-01 seemed to have a significant effect on the HFS, compared with placebo. According to the results of this clinical trial, BRN-01 may be considered a new therapeutic option with a safe profile for hot flashes in menopausal women who do not want or are not able to take hormone replacement therapy or other recognized treatments for this indication.
Laboratoires Boiron provided BRN-01, its matching placebo, and financial support for the study. Randomization and allocation were carried out centrally by Laboratoires Boiron. I would argue that the treatment time in this study was way too short for generating a therapeutic response. The evolution of the HFS in the two groups was assessed by analysis of the area under the curve (AUC) of the mean scores recorded weekly from each patient in each group over the duration of the study, including those at enrollment (before any treatment). I wonder whether this method was chosen only when the researchers noted that the HFS at the pre-defined time points did not yield a significant result or whether it was pre-determined (elsewhere in the methods section we are told that “The primary evaluation criterion was the effect of BRN-01 on the HFS, compared with placebo. The HFS was defined as the product of the daily frequency and intensity of all hot flashes experienced by the patient, graded by the women from 1 to 4 (1 = mild; 2 = moderate; 3 = strong; 4 = very strong). These data were recorded by the women on a self-administered questionnaire, assisted by a telephone call from a clinical research associate. Data were collected (i) during the first 2 days after enrolment and before any medication had been taken; (ii) then every Tuesday and Wednesday of each week until the 11th week of treatment, inclusive; and (iii) finally, every day of the 12th week of treatment.”). Two of the authors of this paper are employees of Boiron.
THE SECOND STUDY
The second trial was aimed at finding out “whether a well-known and frequently prescribed homeopathic preparation could mitigate post-operative pain.” It was a randomized, double-blind, placebo-controlled trial to evaluate the efficacy of the homeopathic preparation Traumeel S® in minimizing post-operative pain and analgesic consumption following surgical correction of hallux valgus. Eighty consecutive patients were randomized to receive either Traumeel tablets or an indistinguishable placebo, and took primary and rescue oral analgesics as needed. Maximum numerical pain scores at rest and consumption of oral analgesics were recorded on day of surgery and for 13 days following surgery. Traumeel was not found superior to placebo in minimizing pain or analgesic consumption over the 14 days of the trial, however a transient reduction in the daily maximum post-operative pain score favoring the Traumeel arm was observed on the day of surgery, a finding supported by a treatment-time interaction test (p = 0.04). The authors concluded that Traumeel was not superior to placebo in minimizing pain or analgesic consumption over the 14 days of the trial. A transient reduction in the daily maximum post-operative pain score on the day of surgery is of questionable clinical importance.
Traumeel is a mixture of 6 ingredients, 4 of which are in the D2 potency. Thus it neither is administered as a homeopathic remedy (no ‘like cures like’) nor is it highly diluted. In fact, it is not homeopathy at all but belongs to a weird offspring of homeopathy called ‘homotoxicology’ [this is an explanation from my book: Homotoxicology is a method inspired by homeopathy which was developed by Hans Heinrich Reckeweg (1905 – 1985). He believed that all or most illness is caused by an overload of toxins in the body. The toxins originate, according to Reckeweg, both from the environment and from the malfunction of physiological processes within the body. His treatment consists mainly in applying homeopathic remedies which usually consist of combinations of single remedies, because health cannot be achieved without ridding the body of toxins. The largest manufacturer and promoter of remedies used in homotoxicology is the German firm Heel.] The HEEL Company (Baden-Baden, Germany) provided funding for the performance and monitoring of this project, supplied the study medication and placebo, and prepared the randomization list. The positive outcome mentioned in the authors’ conclusion refers to a secondary endpoint. I would argue that the authors should not have noted it there and should have made it clear that the trial generated a negative result.
THE THIRD STUDY
Finally, the third of the 3 ‘rigorous’ studies “evaluated the effectiveness of the homeopathic preparation Plumbum Metallicum (PM) in reducing the blood lead levels of workers exposed to this metal.” The Brazilian researchers recruited 131 workers to this RCT who took PM in the CH15 potency or placebo for 35 days (10 drops twice daily). Thereafter, the percentage of workers whose lead level had fallen by at least 25% did not differ between the groups, both on intention to treat and per protocol analyses. The authors concluded that PM “had no effect in this study in terms of reducing serum lead in workers exposed to lead.”
This study lacks a power calculation, and arguably the period might have been too short to show an effect. The trial was published in the journal HOMEOPATHY which, some might argue, has not the most rigorous of peer-review procedures.
The third study seems the most rigorous by far, in my view. The other two trials are seriously under-whelming in several respects, primarily because we cannot be sure how much influence the commercial interests of the sponsor had on their findings. I am sure others will spot weaknesses in all three trials that I failed to see.
Mathie et al partly disagree with my assessment when they write in their paper: “We report separately our model validity assessments of these trials, evaluating consequently their overall quality based on a GRADE-like principle of ‘downgrading’ : two trials [23, 25] rated here as reliable evidence were downgraded to ‘low quality’ overall due to the inadequacy of their model validity; the remaining trial with reliable evidence  was judged to have adequate model validity. The latter study  thus comprises the sole RCT that can be designated ‘high quality’ overall by our approach, a stark finding that reveals further important aspects of the preponderantly low quality of the current body of evidence in non-individualised homeopathy.”
What Mathie et al seem to forget entirely is that none of the 3 RCTs is a trial of homeopathy as defined by treatment according to the ‘like cures like’ principle. The authors of the second study acknowledge this fact by stating: “Homeopathic purists may find fault in the administration of a standardized combination homeopathic formula to all patients, based upon clinical diagnosis – as opposed to the individualized manner dictated by standard homeopathic practice.”
So, which ever way we look upon this evidence, we cannot possibly deny that the evidence for non-individualised homeopathy is rubbish.
D D Palmer was born on March 7, 1845; so, why do chiros celebrate the ‘CHIROPRACTIC AWARENESS WEEK’ from 10 – 16 of April? Perhaps out of sympathy with the homeopaths (many US chiros also use homeopathy) who had their ‘big week’ during the same period? Please tell me, I want to know!
Anyway, the HAW almost ‘drowned’ the CAW – but only almost.
The British Chiropractic Association did its best to make sure we don’t forget the CAW. On their website, we find an article that alerts us to their newest bit of research. Here are some excerpts:
The consumer survey by the British Chiropractic Association (BCA) of more than 2,000 UK adults who currently suffer from back or neck pain, or have done so in the past, found that almost three in five (56%) people experienced pain after using some form of technological device. Despite this, only 27% of people surveyed had limited or stopped using their devices due to concerns for their back or neck health and posture. The research showed people were most likely to experience back or neck pain after using the following technological devices:
• Laptop computer (35%)
• Desktop computer (35%)
• Smart phone (22%)
• Tablet (20%)
• Games console (17%)
The age group most likely to experience back or neck pain when using their smart phone were 16-24 year olds, while nearly half (45%) of young adults 25-34 year olds) admitted to experiencing back or neck pain after using a laptop. One in seven (14%) 16-24 year olds attributed their back or neck pain to virtual reality headsets.
As part of Chiropractic Awareness Week (10-16 April) the BCA is calling for technology companies to design devices with posture in mind, to help tech proof our back health. BCA chiropractor Rishi Loatey comments: “We all know how easy it is to remain glued to our smart phone or tablet, messaging friends or scrolling through social media. However, this addiction to technology could be causing changes to posture, which can lead to increased pressure on the muscles, joints and discs in the spine. Technology companies are now starting to issue older phone models which hark back to a time before smart phones enabled people to do everything from check emails and take pictures, to internet banking. Returning to a time of basic functionality, which may see people look to limit the time spent on their phone, can only be good news for our backs. Yet, in an age where people can now track their health and wellbeing using their phone, technology companies should also start looking at ways to make their devices posture friendly from the outset, encouraging us to take time away from our desks and breaks from our scrolling, gaming and messaging.”
END OF QUOTE
So, here we have it: another piece of compelling, cutting edge research by the BCA. They have made us giggle before but rarely have I laughed so heartily about a ‘professional’ organisation confusing so unprofessionally correlation with causation.
Considering the amount of highly public blunders they managed to inflict on the profession in recent years, I have come to the conclusion that the BCA is a cover organisation of BIG PHARMA with the aim of giving chiropractic a bad name!
Tui Na is a massage technique that is based on the Taoist principles of TCM. It involves a range of manipulations usually performed by an operator’s finger, hand, elbow, knee, or foot applied to muscle or soft tissue at specific parts of the body. According to one website of TCM-proponents “Tui Na makes use of various hand techniques in combination with acupuncture and other manipulation techniques. To enhance the healing process, the practitioner may recommend the use of Chinese herbs. Many of the techniques used in this massage resemble that of a western massage like gliding, kneading, vibration, tapping, friction, pulling, rolling, pressing and shaking. In Tui Na massage, the muscles and tendons are massaged with the help of hands, and an acupressure technique is applied to directly affect the flow of Qi at different acupressure points of the body, thus facilitating the healing process. It removes the blockages and keeps the energy moving through the meridians as well as the muscles. A typical session of Tui Na massage may vary from thirty minutes to an hour. The session timings may vary depending on the patient’s needs and condition. The best part of the therapy is that it relaxes as well as energizes the person. The main benefit of Tui Na massage is that it focuses on the specific problem, whether it is an acute or a chronic pain associated with the joints, muscles or a skeletal system. This technique is very beneficial in reducing the pain of neck, shoulders, hips, back, arms, highs, legs and ankle disorders. It is a very effective therapy for arthritis, pain, sciatica and muscle spasms. Other benefits of this massage therapy include alleviation of the stress related disorders like insomnia, constipation, headaches and other disorders related to digestive, respiratory and reproductive systems. The greatest advantage of Tui Na is that it focuses on maintaining overall balance with both physical and mental health. Any one who wants to avoid the side effects of drugs or a chemical based treatment can adopt this effective massage technique to alleviate their pain. Tui Na massage therapy is now becoming a more common therapy method due to its focus on specific problems rather than providing a general treatment.”
This clearly begs the question IS IT EFFECTIVE?
This systematic review assessed the evidence of Tui Na for cervical radiculopathy. Seven databases were searched. Randomised controlled trials (RCTs) incorporating Tui Na alone or Tui Na combined with conventional treatment were included. Five studies involving 448 patients were found. The pooled analysis from the 3 trials indicated that Tui Na alone showed a significant lowering immediate effects on pain score with moderate heterogeneity compared to cervical traction. The meta-analysis from 2 trials revealed significant immediate effects of Tui Na plus cervical traction in improving pain score with no heterogeneity compared to cervical traction alone. None of the RCTs mentioned adverse effects. There was very low quality or low quality evidence to support the results.
The authors concluded that “Tui Na alone or Tui Na plus cervical traction may be helpful to cervical radiculopathy patients, but supportive evidence seems generally weak. Future clinical studies with low risk of bias and adequate follow-up design are recommended.”
In my view, this is a misleading conclusion. A correct one would have been: THE CURRENT EVIDENCE IS INSUFFICIENT TO DRAW ANY CONCLUSIONS ABOUT THE EFFECTIVENESS OF TUI NA.
Here are some of the most obvious reasons:
- there are far too few studies for a firm conclusion,
- the included RCTs lack scientific rigour,
- all trials originate from China where reliability seems to be a serious problem,
- traction is not a useful therapy for radiculopathy,
- the primary studies violate research ethics by not reporting adverse effects.
Personally, I am getting very tired of conclusions stating ‘…XY MAY BE EFFECTIVE/HELPFUL/USEFUL/WORTH A TRY…’ It is obvious that the therapy in question MAY be effective, otherwise one would surely not conduct a systematic review. If a review fails to produce good evidence, it is the authors’ ethical, moral and scientific obligation to state this clearly. If they don’t, they simply misuse science for promotion and mislead the public. Strictly speaking, this amounts to scientific misconduct.
Drug and alcohol dependencies are notoriously difficult to treat effectively. Patients and their families are often desperate and willing to try anything. This seems like an ideal ground for acupuncturists who are, in my experience, experts in putting up smokescreens hiding the true value of their treatment.
The best way to determine the value of any intervention is probably conducting a systematic review of the evidence from rigorous clinical trials. Today we are in the fortunate position to have not just one of those articles; but do they really tell us the truth?
This brand-new systematic review investigated the effects of acupuncture on alcohol-related symptoms and behaviors in patients with this disorder. The PubMed database was searched until 23 August 2016, and reference lists from review studies were also reviewed. The inclusion criteria were the following: (1) being published in a peer-reviewed English-language journal, (2) use of randomized controlled trials (RCTs), (3) assessing the effects of acupuncture on psychological variables in individuals with a primary alcohol problem, and (4) reporting statistics that could be converted to effect sizes.
Seventeen studies were identified for a full-text inspection, and seven (243 patients) of these met our inclusion criteria. The outcomes assessed at the last post-treatment point and any available follow-up data were extracted from each of the studies. Five studies treated patients by inserting a needle into several acupoints in each ear. Two studies stimulated body points with or without ear stimulation. Four studies treated control patients with a placebo needle or under a completely different type of intervention, such as relaxation or transdermal stimulation, whereas the remaining studies inserted needles into nonspecific points. The patients were treated for 2 weeks to 3 months, and the treatment duration per session was 15–45 min. The results of the meta-analysis demonstrated that an acupuncture intervention had a stronger effect on reducing alcohol-related symptoms and behaviours than did the control intervention. A beneficial but weak effect of acupuncture treatment was also found in the follow-up data.
The authors concluded that although our analysis showed a significant difference between acupuncture and the control intervention in patients with alcohol use disorder, this meta-analysis is limited by the small number of studies included. Thus, a larger cohort study is required to provide a firm conclusion.
I am used to reading poor research papers, but this one is like a new dimension. Here are just the most obvious flaws:
- by searching just one database, the likelihood of missing studies is huge,
- by excluding non-English papers, the review automatically becomes non-systematic,
- the included studies differed vastly in many respects and can therefore not be pooled.
As it happens, a further meta-analysis has just been published. Here is its abstract:
Acupuncture has been widely used as a treatment for alcohol dependence. An updated and rigorously conducted systematic review is needed to establish the extent and quality of the evidence on the effectiveness of acupuncture as an intervention for reducing alcohol dependence. This review aimed to ascertain the effectiveness of acupuncture for reducing alcohol dependence as assessed by changes in either craving or withdrawal symptoms.
In this systematic review, a search strategy was designed to identify randomised controlled trials (RCTs) published in either the English or Chinese literature, with a priori eligibility criteria. The following English language databases were searched from inception until June 2015: AMED, Cochrane Library, EMBASE, MEDLINE, PsycINFO, and PubMed; and the following Chinese language databases were similarly searched: CNKI, Sino-med, VIP, and WanFang. Methodological quality of identified RCTs was assessed using the Jadad Scale and the Cochrane Risk of Bias tool.
Fifteen RCTs were included in this review, comprising 1378 participants. The majority of the RCTs were rated as having poor methodological rigour. A statistically significant effect was found in the two primary analyses: acupuncture reduced alcohol craving compared with all controls (SMD = −1.24, 95% CI = −1.96 to −0.51); and acupuncture reduced alcohol withdrawal symptoms compared with all controls (SMD = −0.50, 95% CI = −0.83 to −0.17). In secondary analyses: acupuncture reduced craving compared with sham acupuncture (SMD = −1.00, 95% CI = −1.79 to −0.21); acupuncture reduced craving compared with controls in RCTs conducted in Western countries (SMD = −1.15, 95% CI = −2.12 to −0.18); and acupuncture reduced craving compared with controls in RCTs with only male participants (SMD = −1.68, 95% CI = −2.62 to −0.75).
This study showed that acupuncture was potentially effective in reducing alcohol craving and withdrawal symptoms and could be considered as an additional treatment choice and/or referral option within national healthcare systems.
This Meta-analysis is only a little better than the first, I am afraid. What its conclusions do not sufficiently reflect, in my view, is the fact that the quality of the primary studies was mostly very poor – too poor to draw conclusions from (other than ‘acupuncture research is usually lousy’; see figure below). Therefore, I fail to see how the authors could draw the relatively firm and positive conclusions cited above. In my view, they should have stated something like this: DUE TO THE RISK OF BIAS IN MANY TRIALS, THE EFFECTIVENESS OF ACUPUNCTURE REMAINS UNPROVEN.
The authors of the first meta-analysis open the discussion by proudly declaring that “the present study is the first meta-analysis to examine the effect of acupuncture treatment on patients with alcohol use disorder and to provide data on the magnitude of this effect on alcohol-related clinical symptoms and behaviours.” They discretely overlook this meta-analysis from 2009 (and several others which even their rudimentary search would have identified):
Nineteen electronic databases, including English, Korean, Japanese, and Chinese databases, were systematically searched for RCTs of acupuncture for alcohol dependence up to June 2008 with no language restrictions. The methodological qualities of eligible studies were assessed using the criteria described in the Cochrane Handbook.
Eleven studies, which comprised a total of 1,110 individual cases, were systematically reviewed. Only 2 of 11 trials reported satisfactorily all quality criteria. Four trials comparing acupuncture treatment and sham treatments reported data for alcohol craving. Three studies reported that there were no significant differences. Among 4 trials comparing acupuncture and no acupuncture with conventional therapies, 3 reported significant reductions. No differences between acupuncture and sham treatments were found for completion rates (Risk Ratio = 1.07, 95% confidence interval, CI = 0.91 to 1.25) or acupuncture and no acupuncture (Risk Ratio = 1.15, 95% CI = 0.79 to 1.67). Only 3 RCTs reported acupuncture-related adverse events, which were mostly minimal.
The results of the included studies were equivocal, and the poor methodological quality and the limited number of the trials do not allow any conclusion about the efficacy of acupuncture for treatment of alcohol dependence. More research and well-designed, rigorous, and large clinical trials are necessary to address these issues.
One does not need to be an expert in interpreting meta-analyses, I think, to see that this paper is more rigorous than the new ones (which incidentally were published in the very dubious journals). And this is why I trust the conclusions of this last-named meta-analysis more than those of the new one: the efficacy of acupuncture remains unproven. And this means that we should not employ or promote it for routine care.
How Jackfruit Kills Cancer… This title hardly left any doubt that jackfruit (Artocarpus heterophyllus Lam) is effective in curing cancer. The website continued in this vein:
“Jackfruit contains phytonutrients like lignans, saponins, and isoflavones, which have anticancer, antihypertensive, anti-ulcer, antioxidant, and anti-aging properties (2).
Lastly, the cancer-preventing abilities of the fruit are due in part to dietary TF-binding lectins (8). The pulp has the ability to reduce the mutagenicity of carcinogens and combat the proliferation of cancer cells (9).
In addition, the fruit contains carotenoids, flavonoids, and polyphenols that lower blood pressure, fight stomach ulcers, boost metabolism, support nerve function, and play a role in hormone synthesis. They also contain polysaccharides that boost immunity by interacting with white blood cells, including T cells, monocytes, macrophages, and polymorphonuclear lymphocytes (10).
Each part of the fruit and tree can be used: the flowers help stop bleeding in open wounds, prevent ringworm infestations, and heal cracks in dry feet while the root is used to treat skin diseases, asthma, and diarrhea. Additionally, the wood has a sedative and abortifacient effect…”
END OF QUOTE
To many desperate cancer patients, this would sound convincing, not least because the references provided by the author look sophisticated and seem to back up most of the claims made.
But where are the references to clinical trials showing that jackfruit does cure this or that type of cancer? Where is the evidence that it does “lower blood pressure, fight stomach ulcers, boost metabolism, support nerve function, and play a role in hormone synthesis”? Where are the data to prove that it does “boost immunity”?
I did conduct a ‘rough and ready’ Medline search and found precisely nothing; not a single clinical trial that would confirm the multiple claims made above.
You are not surprised?
Neither am I!
But what about the desperate cancer patients?
How many fell for the scam? How many gave up their conventional cancer treatments and used jackfruit instead? How many consumers know that it is not unusual for plants to contain lignans, saponins, isoflavones and many other ingredients that have amazing effects in vitro? How many know that this rarely translates into meaningful health effects in human patients?
We will never know.
One thing we do know, however, is that articles like this one can cost lives, and that alternative cancer cures are and always will be a myth.
THE CHRONICLE OF CHIROPRACTIC is not a publication I usually read, I have to admit. But perhaps I should, because this article from its latest edition is truly fascinating. Here are the crucial excerpts:
“A so called “debate” on vertebral subluxation was held at the recent chiropractic educational conference held by the controlling factions of the Chiropractic Cartel: The World Federation of Chiropractic, the Association of Chiropractic Colleges and the American Chiropractic Association. Every few years this faction of the profession makes an attempt to disparage vertebral subluxation and those who practice in a subluxation model by trotting out its long list of Subluxation Deniers.
This year was no different.
David Newell, who is a Senior Lecturer at the Anglo European College of Chiropractic, made a number of unsubstantiated claims and engaged in logical fallacies that would shock even the casual observer. As an example, Newell made the statement:
“The subluxation as vitalistic concept, an impediment in and of itself to health and well being, impeding the expression of higher intelligence is not only entirely bereft of any evidence whatsoever but is a complete non starter even as a scientific question.”
…Newell claimed that what is dangerous about the use of vertebral subluxation are concepts and behavior associated with its use. Newell stated that subluxations are used by some in the profession to “scare or misinform patients” and gave the following examples of claims he has issues with:
- You cannot be healthy with them
- They will lead to serious disease
- Chiropractors are the only ones that can help
- A chiropractic manipulation is unique
- You need to come back for the rest of your life
- You need to bring your children otherwise they will not develop properly
Newell claimed that such statements are “confusing, un-evidenced and detrimental to our standing as a profession in the outside world” and that “at worse, sometimes used to justify approaches to care and practice models that are unacceptable both inside and outside of the profession.”
Newell … continued his tirade against his perceived threat to public health stating vertebral subluxation and the concepts attached to it are: “. . . used to generate dependancy through fear or coercion. Here, use of such words and concepts essentially as smoke screens for a model of care dominated by a coercive business ethic are strongly reputationally damaging and are not OK.” …Newell further claimed that the concept of ” . . . subluxation as an impediment to innate intelligence is bereft of science and evidence” and that “. . . this approach will be inadmissible to characterise a modern healthcare profession. Describing the profession in such language will further isolate and marginalise.”…”The irony” he states “. . . is of course that there are much better explanations, concepts and terms. Much of what is seen in practice can be explained by sound science and scientific language and so a subluxation model isn’t even needed.”
He went on to engage in further expressions of logical fallacies by stating: “Even on a simple level, science has yet to answer questions as to what a subluxation is as a defined entity, can it be validly and reliably identified, can it be validly and reliably shown to have gone post manipulation and is such disappearance associated with meaningful clinical change in patients.”
In reality, there is a rich evidence base that demonstrates the validity and reliability of numerous methods of measurements focused on the various components of vertebral subluxation as well as evidence demonstrating reduction or correction of it with resulting positive health outcomes.
Unfortunately, most simply go along with statements such as Newell’s either out of ignorance, simple aquiesence or collegiality.
Imagine the plight of students in a chiropractic program being exposed to Newell’s dogma, scientism and denial of even the existence of vertebral subluxation. That he is even given a stage and an audience is a failure of leadership within the ranks of those who purport to embrace the vitalistic concept of vertebral subluxation.
We laugh and mock those who contend the Earth is flat, yet Subluxation Deniers are given voice by schools and political organizations along with a role in determining the subluxation research agenda. And its the leadership on the traditional, conservative side of the profession that does this – as evidenced by his even being entertained at an educational conference billed as the largest and most important gathering of chiropractic educators and researchers.
Not a single objection to his, or any other Deniers, participation by the leadership in the vitalistic faction. In fact, quite the opposite – he was given the opportunity to spew his Flat Earth nonsense to a wide audience who educate the future of this profession.
Imagine a meeting at NASA where a Flat Earther is given a voice and a vote on the Mars Mission.
This was and is a failure of leadership within the vitalistic, conservative, traditional faction of the chiropractic profession.”
END OF EXCERTS
On this blog, we have heard again and again that the chiropractic profession is in the middle of a fundamental reform, that it has given up the idiotic concepts of its founders, that it has joined the 21st century, that it is becoming evidence-based, that progress is being made etc. etc. However, sceptics have always doubted these claims and pointed out that chiropractic minus its traditional concepts would merely become a limited type of physiotherapy.
From the above article, I get the impression that the notion of reform might be a bit optimistic. The old guard seems to be as alive and powerful as ever, fighting as fiercely as always to preserve chiropractic’s nonsensical cult.
Some will, of course, claim that the above article shows exactly the opposite of what I just stated. They will try to persuade us that it is evidence for the struggle of the new generation of chiropractors instilling reason into their brain-dead peers. It is evidence, they will claim, for the fact that there is a healthy discussion within the profession.
Yet this is simply not true: The maligned Mr Newell is NOT a chiropractor!
To me, the above article suggests that, for the foreseeable future, chiropractic will remain where it always has been: firmly anchored in the realm of quackery.
Therapeutic Touch is a therapy mostly popular with nurses. We have discussed it before, for instance here, here, here and here. To call it implausible would be an understatement. But what does the clinical evidence tell us? Does it work?
This literature review by Iranian authors was aimed at critically evaluating the data from clinical trials examining the clinical efficacy of therapeutic touch as a supportive care modality in adult patients with cancer.
Four electronic databases were searched from the year 1990 to 2015 to locate potentially relevant peer-reviewed articles using the key words therapeutic touch, touch therapy, neoplasm, cancer, and CAM. Additionally, relevant journals and references of all the located articles were manually searched for other potentially relevant studies.
The number of 334 articles was found on the basis of the key words, of which 17 articles related to the clinical trial were examined in accordance with the objectives of the study. A total of 6 articles were in the final dataset in which several examples of the positive effects of healing touch on pain, nausea, anxiety and fatigue, and life quality and also on biochemical parameters were observed.
The authors concluded that, based on the results of this study, an affirmation can be made regarding the use of TT, as a non-invasive intervention for improving the health status in patients with cancer. Moreover, therapeutic touch was proved to be a useful strategy for adult patients with cancer.
This review is badly designed and poorly reported. Crucially, its conclusions are not credible. Contrary to what the authors stated when formulating their aims, the methods lack any attempt of critically evaluating the primary data.
A systematic review is more than a process of ‘pea counting’. It requires a rigorous assessment of the risk of bias of the included studies. If that crucial step is absent, the article is next to worthless and the review degenerates into a promotional excercise. Sadly, this is the case with the present review.
You may think that this is relatively trivial (“Who cares what a few feeble-minded nurses do?”), but I would disagree: if the medical literature continues to be polluted by such irresponsible trash, many people (nurses, journalists, healthcare decision makers, researchers) who may not be in a position to see the fatal flaws of such pseudo-reviews will arrive at the wrong conclusions and make wrong decisions. This will inevitably contribute to a hindrance of progress and, in certain circumstances, must endanger the well-being or even the life of vulnerable patients.
It was a BBC journalist who alerted me to this website (and later did an interview to be broadcast today, I think). Castle Treatments seem to have been going already for 12 years; they specialise in treating drug and alcohol dependency. And they are very proud of what they have achieved:
“We are the U.K.’s leading experts in advanced treatments to help clients to stop drinking, stop cocaine use and stop drug use. Over the last 12 years we have helped over 9,000 private clients stop using: alcohol, cocaine, crack, nicotine, heroin, opiates, cannabis, spice, legal highs and other medications…
All other treatment methods to help people stop drinking or stop using drugs have a high margin for error and so achieve very low success rates as they use ‘slow and out-dated methods’ such as talking therapies (hypnosis, counselling, rehab, 12 steps, CBT etc) or daily medications (pharma meds, sprays, opiates, subutex etc) which don’t work for most people or most of the time.
This is because none of these methods can remove the ’cause’ of the problem which is the ‘frequency of the substance’ itself. The phase signal of the substance maintains the craving or desire for that substance, once neutralised the craving/desire has either gone or is greatly diminished therefore making it much easier to stop drinking or using drugs as per the client feedback.
When compared to any other method there is no doubt our treatments produce the best results. Over the last 12 years we have helped over 9,000 clients the stop drinking, stop cocaine use or stop using drugs with excellent results as each client receives exactly the same treatment program tailored to their substance(s) which means our success rates are consistently high, making our advanced treatment the logical and natural choice when you want help.
Our technicians took basic principles in physics and applied them to new areas to help with addiction and dependency issues. Our treatment method uses specific phase signals (frequency) to help:
- neutralise any substance and reduce physical dependency
- improve and restore physical & mental health
When the substance is neutralised, the physical urge or craving has ‘gone or is greatly diminished’ therefore making it much easier to stop drinking or using drugs. The body can also absorb beneficial input frequencies so physically and mentally our clients ‘feel much better‘ and so find it much easier to ‘stop and regain control’…
The body (muscle, tissue, bones, cells etc) radiate imbalances including disease, physical, emotional and psychological conditions which have their own unique frequencies that respond to various ‘beneficial input frequencies’ (Hz) or ‘electroceuticals’ which can help to improve physical and mental health hence why our clients feel so much better during/after treatment…”

To me this sounds like nonsense on stilts.
Bioresonance is, as far as I can see, complete baloney. It originates from Germany and uses an instrument that is not dissimilar to the e-meter of scientology (its inventor had links to this cult). This instrument is supposed to pick up unhealthy frequencies from the body, inverses them and thus treats the root cause of the problem.
There are two seemingly rigorous positive studies of bioresonance. One suggested that it is effective for treating GI symptoms. This trial was, however, tiny. The other study suggested that it works for smoking cessation. Both of these articles appeared in a CAM journal and have not been independently replicated. A further trial published in a conventional journal reported negative results. In 2004, I published an article in which I used the example of bioresonance therapy to demonstrate how pseudo-scientific language can be used to cloud important issues. I concluded that it is an attempt to present nonsense as science. Because this misleads patients and can thus endanger their health, we should find ways of minimizing this problem (I remember being amazed that a CAM journal published this critique). More worthwhile stuff on bioresonance and related topics can be found here, here and here.
There is no good evidence that bioresonance is effective for drug or alcohol dependency (and even thousands of testimonials do not amount to evidence: THE PLURAL OF ANECDOTE IS ANECDOTES, NOT EVIDENCE!!!). Claiming otherwise is, in my view, highly irresponsible. If I then consider the fees Castle Treatments charge (Alcohol Support: Detox 1: £2,655.00, Detox 2: £3,245.00, Detox 3: £3,835.00) I feel disgusted and angry.
I hope that publishing this post somehow leads to the closure of Castle Treatments and similar clinics.
The title of the press-release was impressive: ‘Columbia and Harvard Researchers Find Yoga and Controlled Breathing Reduce Depressive Symptoms’. It certainly awoke my interest and I looked up the original article. Sadly, it also awoke the interest of many journalists, and the study was reported widely – and, as we shall see, mostly wrongly.
According to its authors, the aims of this study were “to assess the effects of an intervention of Iyengar yoga and coherent breathing at five breaths per minute on depressive symptoms and to determine optimal intervention yoga dosing for future studies in individuals with major depressive disorder (MDD)”.
Thirty two subjects were randomized to either the high-dose group (HDG) or low-dose group (LDG) for a 12-week intervention of three or two intervention classes per week, respectively. Eligible subjects were 18–64 years old with MDD, had baseline Beck Depression Inventory-II (BDI-II) scores ≥14, and were either on no antidepressant medications or on a stable dose of antidepressants for ≥3 months. The intervention included 90-min classes plus homework. Outcome measures were BDI-II scores and intervention compliance.
Fifteen HDG and 15 LDG subjects completed the intervention. BDI-II scores at screening and compliance did not differ between groups. BDI-II scores declined significantly from screening (24.6 ± 1.7) to week 12 (6.0 ± 3.8) for the HDG (–18.6 ± 6.6; p < 0.001), and from screening (27.7 ± 2.1) to week 12 (10.1 ± 7.9) in the LDG. There were no significant differences between groups, based on response (i.e., >50% decrease in BDI-II scores; p = 0.65) for the HDG (13/15 subjects) and LDG (11/15 subjects) or remission (i.e., number of subjects with BDI-II scores <14; p = 1.00) for the HDG (14/15 subjects) and LDG (13/15 subjects) after the 12-week intervention, although a greater number of subjects in the HDG had 12-week BDI-II scores ≤10 (p = 0.04).
The authors concluded that this dosing study provides evidence that participation in an intervention composed of Iyengar yoga and coherent breathing is associated with a significant reduction in depressive symptoms for individuals with MDD, both on and off antidepressant medications. The HDG and LDG showed no significant differences in compliance or in rates of response or remission. Although the HDG had significantly more subjects with BDI-II scores ≤10 at week 12, twice weekly classes (plus home practice) may rates of response or remission. Although the HDG, thrice weekly classes (plus home practice) had significantly more subjects with BDI-II scores ≤10 at week 12, the LDG, twice weekly classes (plus home practice) may constitute a less burdensome but still effective way to gain the mood benefits from the intervention. This study supports the use of an Iyengar yoga and coherent breathing intervention as a treatment to alleviate depressive symptoms in MDD.
The authors also warn that this study must be interpreted with caution and point out several limitations:
- the small sample size,
- the lack of an active non-yoga control (both groups received Iyengar yoga plus coherent breathing),
- the supportive group environment and multiple subject interactions with research staff each week could have contributed to the reduction in depressive symptoms,
- the results cannot be generalized to MDD with more acute suicidality or more severe symptoms.
In the press-release, we are told that “The practical findings for this integrative health intervention are that it worked for participants who were both on and off antidepressant medications, and for those time-pressed, the two times per week dose also performed well,” says The Journal of Alternative and Complementary Medicine Editor-in-Chief John Weeks
At the end of the paper, we learn that the authors, Dr. Brown and Dr. Gerbarg, teach and have published Breath∼Body∼Mind©, a technique that uses coherent breathing. Dr. Streeter is certified to teach Breath∼Body∼Mind©. No competing financial interests exist for the remaining authors.
Taking all of these issues into account, my take on this study is different and a little more critical:
- The observed effects might have nothing at all to do with the specific intervention tested.
- The trial was poorly designed.
- The aims of the study are not within reach of its methodology.
- The trial lacked a proper control group.
- It was published in a journal that has no credibility.
- The limitations outlined by the authors are merely the tip of an entire iceberg of fatal flaws.
- The press-release is irresponsibly exaggerated.
- The authors have little incentive to truly test their therapy and seem to use research as a means of promoting their business.
