I thought I had seen everything that is lamentable about homeopathy. When I came across this article, I had to change my opinion. It is a more despicable, unethical and dangerous promotion of falsehoods than I could have imagined.

Strong words? Read for yourself:

There are treatments that can heal vaccine damage, but few physicians in the conventional medical care system know about them, since vaccine injuries are usually denied as the cause of any illness. Some parents with autistic children report that homeopathy has completely reversed their children’s autism and healed other serious health conditions caused by vaccines. This article explains how homeopathic remedies can bring about healing for many types of vaccine injuries.

Homeopathy is not the only treatment that has helped children and adults recover from vaccine damage, but it is the one that is the focus of this article. I will describe how homeopathy can bring about a true cure for the harm that vaccines have caused to children and adults…

It is a tragedy when a normal young child suddenly starts losing the ability to speak sentences or even to speak words after receiving vaccines. The ability to have positive social interactions with other children or adults can disappear in a matter of days after vaccines have been given to children. Intellectual development can be lost and even successful potty training skills can disappear. The ability to sit quietly, listen to a story being read, and the ability to learn can suddenly be replaced with hand flapping, body spinning, head banging, food allergies, asthma, agitation, hyperactivity, learning disabilities, chronic colds and fevers, constant stomach pain, constipation, and a general failure to grow and thrive. There are also serious consequences for adults who use vaccines. Formerly productive adults can lose their independence and become paralyzed, infertile, chronically ill, and even die, because of vaccine damage. It happens every day, yet few people make the connection between their illnesses and vaccine use…

By the time parents fully awaken to the harm that has occurred to their children, many have already resigned themselves to a lifetime of caretaking their disabled children. Some parents will even receive counsel from their physicians to give up their children to the care of the state, because they have no treatments to offer and can offer no hope of recovery. Some physicians will try to convince parents that this is a genetic problem that might be cured someday, but not in the near future. The conventional medical care system leaves parents feeling like helpless victims without any good options. The truth is there are good options for restoring health after vaccine damage, and homeopathy is one of them!…

Homeopathy does not wage war on disease and seek to destroy the symptoms of disease through brute force. It does not bring substances into the body as is done with allopathic drugs, for the purpose of doing hand to hand combat against disease. Instead, homeopathy and its remedies are intended to gently stimulate and strengthen the body so that it can overcome illness through its own vital force and strength. Homeopathic remedies restore the natural ability of the body to defend itself against illness and to heal itself. When this happens, a person is truly cured of what ails him…

Allopathic drugs and treatments do not have a positive effect upon the vital force in the body. They do not improve the strength of a person, and they do not provide for physical, emotional, or mental renewal. Rather, they just suppress symptoms, and add side effects…

You may also wish to ask for a referral from your chiropractor, osteopath, or acupuncturist. Such practitioners are often aware of good homeopaths in the area. Sometimes the person who is responsible for managing supplements and remedies sold at health food stores will be aware of experienced homeopaths as well…

I know, apologists will claim that such extreme idiocy is always the work of a few ‘rotten apples’, even most homeopaths would object to such dangerous and amoral lunacy. But the fact is, they don’t! If you disagree, please show me the protests from homeopaths or other alternative practitioners.

When Wakefield was shown to be a fraud endangering public health with his bogus claims about vaccine damage, there were protests in abundance, and he was ousted by the medical and scientific communities. Where are the protests by the alternative medicine fraternity against this article and the many, many others like it?

NOBODY SHOULD BE ALLOWED TO ENDANGER PUBLIC HEALTH IN THIS WAY.

PS

In case you wonder who wrote the above article, it is John P. Thomas. He is a health writer for Health Impact News. He holds a B.A. in Psychology from the University of Michigan, and a Master of Science in Public Health (M.S.P.H.) from the School of Public Health, Department of Health Administration, at the University of North Carolina at Chapel Hill. John specializes in environmental health, but writes on a variety of issues.

If you ask a chiropractor, you will probably be told that chiropractic spinal manipulation is a safe treatment. Unfortunately this is not quite true, as regular readers of this blog will appreciate. About half of all patients suffer mild to moderate adverse effects after chiropractic treatments and, in addition, many instances of much more serious complications have been documented, including rare cases of Horner syndrome. It results from an interruption of the sympathetic nerve supply to the eye and is characterized by the classic triad of miosis (ie, constricted pupil), partial ptosis, and loss of hemifacial sweating (ie, anhidrosis).

Danish neurologists recently reported the case of a 60-year-old man with no relevant medical history who was admitted to the Department of Neurology with drooping of his right upper eyelid and an ipsilateral contracted pupil, combined with pain, weakness, and numbness in his upper right limb.

The patient had experienced thoracic back pain of moderate intensity with radiating right-sided belt-like chest pain for 7 days. When the discomfort suddenly intensified, he sought chiropractic treatment. Following manipulations of the thoracic and cervical spine, the pain intensity initially lessened. Approximately one hour after chiropractic treatment, the patient experienced the eye and upper limb symptoms described above, for which he sought medical assistance three days later.

A detailed neurologic examination revealed moderate right-sided ptosis and miosis, no facial anhidrosis, decreased strength of the intrinsic and opponens muscles of the right hand, and reduced cutaneous sensation corresponding to the T1 dermatome, with inability to discriminate pain and light touch. The remaining clinical examination, routine blood tests, and vital parameters were unremarkable.

Brain CT scan and CT angiography including the aortic arch and neck vessels were performed and ruled out cerebral stroke and carotid artery dissection, respectively. As clinical signs of Horner syndrome and a concomitant radiating pain to the medial arm were considered suggestive of either a lower brachial plexopathy, i.e., due to a Pancoast tumor, or a radiculopathy, chest X-ray and electroneurography (ENG) were performed. No apical pulmonary pathology was detected. ENG of the right medial cutaneous antebrachial nerve demonstrated a normal sensory action potential (SAP), consistent with the lesion being located proximally to the dorsal spinal root ganglion, thus suggestive of a spinal nerve root lesion. A subsequent MRI of the thoracic spine showed a para-median herniation of the T1-T2 intervertebral disc compressing the right T1 spinal nerve root.

The patient received no surgery, and follow-up examination 6 months later revealed near-complete recovery, with only mild paraesthesia in the T1 segment of his right arm and a subtle ptosis remaining.

Horner syndrome due to a herniated thoracic disc has only been reported 6 times in the English language literature, though never preceded by chiropractic manipulation.

One of the most frequent causes of Horner syndrome is carotid artery dissection, which may occur spontaneously or due to local trauma to the neck region. Chiropractic manipulation as an independent risk factor for neck artery dissection and a consequent stroke is a controversial topic, though multiple cases of Horner syndrome due to ICA dissections subsequent to chiropractic manipulation have been reported. In the patient described here, an ICA dissection was considered unlikely due to the concomitant prominent radiating medial brachialgia and was furthermore ruled out by a CT angiogram of the neck vessels.

This patient experienced the onset of a Horner syndrome and ipsilateral upper limb symptoms shortly after chiropractic treatment, suggesting the cervico-thoracic manipulation as the cause of or at least worsening factor in the T1-T2 disc herniation. Several cases of disc herniations following chiropractic treatment have been reported.

While the definite pathophysiologic mechanism to explain this patient’s Horner syndrome remains unclear, it seems, according to the authors of this case-report, evident that manipulations as a minimum altered the configuration of an already existing disc protrusion.

I have repeatedly stressed that herbal remedies can cause harm in a range of ways. Indian rheumatologists recently enforced this point by publishing a case-report of adrenal suppression caused by herbal remedies.

A 49-year-old male presented with polyarthritis from which he had suffered for more than 10 years. His serum cortisol levels were extremely low, he had vitamin D deficiency, and his rheumatoid factor was negative. He revealed symptoms of adrenal suppression, mainly muscle weakness and suicidal tendency, and few other psychiatric disturbances.

The patient eventually discontinued his herbal medicine. Then, he was put on deflazacort for 12 weeks at 12 mg twice daily and later the dose was tapered to 6 mg/day. Deflazocort, an intermediate-acting corticosteroid, was prescribed to minimize the probable withdrawal symptoms due to the probable presence of dexamethasone or betamethasone (long-acting steroids) presumably from the herbal medication.

The herbal samples of used by the patient was analysed by mass spectrometry. It showed the presence of steroidal compounds by the mass 393.81, which may be dexamethasone or betamethasone.

The authors of this paper believe that the symptoms of adrenal suppression could have precipitated or exacerbated the neuropsychiatric disturbances due to Hypothalamus-Pituitary-Adrenal (HPA) suppression. In their view, adrenal suppression following ingestion of herbal remedies is of major concern. Abrupt withdrawal of such products could precipitate adrenal failure which can be fatal.

It should be added, I think, that such illegal adulterations of herbal remedies have been reported with some regularity, particularly in Indian (and Chinese) preparations. Our systematic review showed that this problem has caused serious harm. The most severe documented adverse effects include agranulocytosis, meningitis, multi-organ failure, perinatal stroke, arsenic, lead or mercury poisoning, malignancies or carcinomas, hepatic encephalopathy, hepatorenal syndrome, nephrotoxicity, rhabdomyolysis, metabolic acidosis, renal or liver failure, cerebral edema, coma, intracerebral haemorrhage, and death.

As under-reporting can be suspected to be huge, we do currently not know how frequent these events are.

In the world of homeopathy, the truth is often much weirder than fiction. Take this recent article, for instance; it was published by the famous lay homeopath Alan Schmukler in the current issue of ‘HOMEOPATHY 4 EVERYONE’.

Before you read the text in question, it might be relevant to explain who Schmukler is: he attended Temple University, where he added humanistic psychology to his passions. After graduating Summa Cum Laude, Phi Beta Kappa and President’s Scholar, he spent several years doing workshops in human relations. Alan also studied respiratory therapy and worked for three years at Einstein Hospital in Philadelphia. Those thousands of hours in the intensive care and emergency rooms taught him both the strengths and limitations of conventional medicine. Schmukler learned about homeopathy in 1991 when he felt he had been cured of an infection with Hepar sulph. He later founded the Homeopathic Study Group of Metropolitan Philadelphia, giving free lectures and hosting the areas best homeopaths to teach. He also helped found and edit Homeopathy News and Views, a popular culture newsletter on homeopathy. He taught homeopathy for Temple University’s Adult Programs, and has been either studying, writing, lecturing or consulting on homeopathy since 1991. He wrote Homeopathy An A to Z home Handbook, which is now available in five languages. Alan Schmukler has been practicing homeopathy for more than two decades and is Chief Editor of Hpathy.com and of Homeopathy4Everyone. He says that his work as Editor is one of his most rewarding experiences.

Now, brace yourself, here is the promised text/satire (in bold); I promise, I did not change a single word:

EIGHT REASONS TO VACCINATE YOUR CHILD

  1. Your child is deficient in Mercury, Aluminum, Formaldehyde, viruses, foreign DNA or other ingredients proven to cause neurological damage.
  2. Your child has an excess of healthy, functioning brain cells.
  3. You need more cash. The National Vaccine Injury Compensation program has paid out 2.8 billion dollars to parents of children injured or killed by vaccines.
  4. You and your husband are feeling alienated and you need a crisis to bring you together.
  5. You believe that pharmaceutical conglomerates which earn billions from vaccines are more credible than consumer groups.
  6. You think thousands of parents who report that their children became autistic two weeks after vaccination are lying.
  7. You don’t see a problem in logic when the government tells you that vaccines work, but that vaccinated children can catch diseases from unvaccinated children.
  8. You think the government should dictate which healing methods you and your children are allowed to use.

Funny? No!

Bad taste? Very much so!

Barmy? I think so!

Dangerous? Yes!

Irresponsible? Most certainly!

Unethical? Yes!

Characteristic for lay homeopathy? Possibly!

There are things that cannot be said too often. In medicine, these are often related to issues that can save lives. In alternative medicine, it is worth remembering that there is nothing that can save more lives than the following rule: EVEN AN APPARENTLY HARMLESS REMEDY WILL BECOME LIFE-THREATENING, IF IT IS USED AS AN ALTERNATIVE TO AN EFFECTIVE THERAPY FOR A SERIOUS CONDITION.

Here is a publication that serves as a very sad reminder of this important axiom.

Japanese physicians recently published a case-report of 2-year-old girl who died of precursor B-cell acute lymphoblastic leukaemia (ALL), the most common cancer in children. She had no remarkable medical history. She was transferred to a hospital because of respiratory distress and died 4 hours after arrival.

Two weeks before her death, she had developed a fever of 39°C, which subsided after the administration of a naturopathic herbal remedy. Subsequently, she developed jaundice one week before death, and her condition worsened on the day of death.

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

With advancements in medical technology, the 5-year survival rate of children with ALL is nearly 90%. However, in this case, the deceased’s parents preferred alternative medicine to evidence-based medicine and had not taken her to a hospital for a medical check-up or immunisation since she was an infant. The authors state that, if she had received routine medical care, she would have a more than 60% chance of being alive 5 years after diagnosis. Therefore, we conclude that the parents should be accused of medical neglect regardless of their motives.

Alternative practitioners who treat their patients in this way, are in my experience often full of good intentions. They remind me of something Bert Brecht one wrote: THE OPPOSITE OF GOOD IS NOT EVIL, IT IS GOOD INTENTIONS.

Ayurvedic medicine has become highly popular in Western countries; it originates, of course, from India, and is considered to be one of the world’s oldest health care systems. Its adherents claim to create harmony between the body, mind, and spirit, maintaining that this balance prevents illness, treats acute conditions, and contributes to a long and healthy life. In India Ayurveda is mainstream and more than 90% of the population are said to use it. Outside India, Ayurveda is usually classified as an alternative therapy.

Ayurvedic treatments can consist of a range of modalities, including herbal remedies taken by mouth. These preparations have often been reported to be contaminated with toxic metals. Despite several case reports of poisoning from such contamination, the epidemiological evidence is still limited. A new paper on this important topic is therefore welcome. It reports on a cluster of lead and mercury toxicity cases which occurred 2011 among a community of users of Ayurvedic remedies in the US.

Following the identification of the index case, adherents of Ayurveda were offered heavy metals screening. The results showed that 46 of 115 participants (40%) had elevated blood lead levels (BLLs) of 10 μg/dl or above, with 9.6% of BLLs at or above 50 μg/dl.

The authors issued the following warning: this is the largest cluster of lead and mercury toxicity following use of Ayurvedic supplements described in the literature in the US. Contamination of herbal products is a public health issue of global significance. There are few regulations addressing contamination of “natural” products or supplements.

Rasa shastra, the practice of adding metals, minerals or gems to herbal preparations, is a well-documented part of Ayurveda. Adverse reactions to herbs are described in traditional Ayurvedic texts, but practitioners tend to be reluctant to admit that their remedies could be toxic and that reliable information on their risks is not readily available.

Already in 1990, a study on Ayurvedic medicines in India found that 41% of the products tested contained arsenic, and that 64% contained lead and mercury. A 2004 study found toxic levels of heavy metals in 20% of Ayurvedic preparations sold in the Boston area. A 2008 study of more than 230 products found that approximately 20% of remedies (and 40% of rasa shastra medicines) purchased over the Internet from U.S. and Indian suppliers contained lead, mercury or arsenic.

My 2002 systematic review summarised all the available evidence and concluded that heavy metals, particularly lead, have been a regular constituent of traditional Indian remedies. This has repeatedly caused serious harm to patients taking such remedies. The incidence of heavy metal contamination is not known, but one study shows that 64% of samples collected in India contained significant amounts of lead (64% mercury, 41% arsenic and 9% cadmium). These findings should alert us to the possibility of heavy metal content in traditional Indian remedies and motivate us to consider means of protecting consumers from such risks.

Despite these concerns, Ayurveda-fans continue to believe that the toxicity of these remedies is reduced through the purification processes of Ayurvedic remedy preparation. Bizarrely, they may involve prayers as well as physical pharmacy techniques.

The Indian government ruled that Ayurvedic products must be labelled with their metallic content. However, one Indian expert, has been quoted claiming that “the absence of post-market surveillance and the paucity of test laboratory facilities [in India] make the quality control of Ayurvedic medicines exceedingly difficult at this time”. In the US, most Ayurvedic products are marketed without having been approved by the FDA. Since 2007, the FDA has placed an import alert on some Ayurvedic products in order to prevent them from entering the US.

Protecting consumers from heavy metal poisoning by Ayurvedic remedies is certainly not easy – but, in the interest of public health, it is a task that we must tackle with some ungency.

Yoga is a popular form of alternative medicine. Evidence for its effectiveness is scarce and generally far from convincing. But at least it is safe! At least this is what yoga enthusiasts would claim. Unfortunately, this is not entirely true; adverse events have also been reported with some regularity. Their frequency is, however, not known.

A new study was aimed at filling this gap. It was conducted to elucidate the frequencies and characteristics of adverse events of yoga performed in classes and the risk factors of such events.

The subjects were 2508 people taking yoga classes and 271 yoga therapists conducting the classes. A survey for yoga class attendees was performed on adverse events that occurred during a yoga class on the survey day. A survey for yoga therapists was performed on adverse events that the therapists had observed in their students to date. Adverse events were defined as “undesirable symptoms or responses that occurred during a yoga class”.

Among 2508 yoga class attendees, 1343 (53.5%) had chronic diseases and 1063 (42.3%) were receiving medication at hospitals. There were 687 class attendees (27.8%) who reported some type of undesirable symptoms after taking a yoga class. Musculoskeletal symptoms such as myalgia were the most common symptoms, involving 297 cases, followed by neurological symptoms and respiratory symptoms. Most adverse events (63.8%) were mild and did not interfere with class participation. The risk factors for adverse events were examined, and the odds ratios for adverse events were significantly higher in attendees with chronic disease, poor physical condition on the survey day, or a feeling that the class was physically and mentally stressful. In particular, the occurrence of severe adverse events that interfered with subsequent yoga practice was high among elderly participants (70 years or older) and those with chronic musculoskeletal diseases.

The authors concluded that the results of this large-scale survey demonstrated that approximately 30% of yoga class attendees had experienced some type of adverse event. Although the majority had mild symptoms, the survey results indicated that attendees with chronic diseases were more likely to experience adverse events associated with their disease. Therefore, special attention is necessary when yoga is introduced to patients with stress-related, chronic diseases.

I find these findings interesting and thought-provoking. The main question that they raise is, I think, the flowing: ARE THERE ANY CONDITIONS FOR WHICH YOGA DEMONSTRABLY GENERATES MORE GOOD THAN HARM?

If we listen to acupuncturists and their supporters, we might get the impression that acupuncture is totally devoid of risk. Readers of this blog will know that this is not quite true. A recent case report is a further reminder that acupuncture can cause serious complications; in extreme cases it can even kill.

A male patient in his late forties died right after an acupuncture treatment. A medico-legal autopsy disclosed severe haemorrhaging around the right vagus nerve in the neck. All other organs were normal, and laboratory findings revealed nothing significant. Thus, the authors of this case-report concluded that the man most probably died from severe vagal bradycardia and/or arrhythmia resulting from vagus nerve stimulation following acupuncture: To the best of our knowledge, this is the first report of a death due to vagus nerve injury after acupuncture.

In total, around 100 deaths have been reported after acupuncture in the medical literature. ‘This is a negligible small figure’ claim acupuncture fans. True, it is a small number, but it could just be the tip of a much larger ice-berg: there is no reporting system that could possibly pick up severe complications, and in the absence of such a scheme, nobody can name reliable incidence rates. And even if the numbers of severe complications and deaths are small – even a single fatality would seem one too many.

The deaths that are currently on record are mostly due to bilateral pneumothorax or cardiac tamponade. The present case of vagus nerve injury seems to be ‘a first’. Perhaps we should watch out for similar events?

IF WE DON’T LOOK, WE DON’T SEE.

Here is another short passage from my new book A SCIENTIST IN WONDERLAND. It describes the event where I was first publicly exposed to the weird and wonderful world of alternative medicine in the UK. It is also the scene which, in my original draft, was the very beginning of the book.

I hope that the excerpt inspires some readers to read the entire book – it currently is BOOK OF THE WEEK in the TIMES HIGHER EDUCATION!!!

… [an] aggressive and curious public challenge occurred a few weeks later during a conference hosted by the Research Council for Complementary Medicine in London. This organization had been established a few years earlier with the aim of conducting and facilitating research in all areas of alternative medicine. My impression of this institution, and indeed of the various other groups operating in this area, was that they were far too uncritical, and often proved to be hopelessly biased in favour of alternative medicine. This, I thought, was an extraordinary phenomenon: should research councils and similar bodies not have a duty to be critical and be primarily concerned about the quality of the research rather than the overall tenor of the results? Should research not be critical by nature? In this regard, alternative medicine appeared to be starkly different from any other type of health care I had encountered previously.

On short notice, I had accepted an invitation to address this meeting packed with about 100 proponents of alternative medicine. I felt that their enthusiasm and passion were charming but, no matter whom I talked to, there seemed to be little or no understanding of the role of science in all this. A strange naïvety pervaded this audience: alternative practitioners and their supporters seemed a bit like children playing “doctor and patient”. The language, the rituals and the façade were all more or less in place, but somehow they seemed strangely detached from reality. It felt a bit as though I had landed on a different planet. The delegates passionately wanted to promote alternative medicine, while I, with equal passion and conviction, wanted to conduct good science. The two aims were profoundly different. Nevertheless, I managed to convince myself that they were not irreconcilable, and that we would manage to combine our passions and create something worthwhile, perhaps even groundbreaking.

Everyone was excited about the new chair in Exeter; high hopes and expectations filled the room. The British alternative medicine scene had long felt discriminated against because they had no academic representation to speak of. I certainly did sympathize with this particular aspect and felt assured that, essentially, I was amongst friends who realized that my expertise and their enthusiasm could add up to bring about progress for the benefit of many patients.
During my short speech, I summarized my own history as a physician and a scientist and outlined what I intended to do in my new post—nothing concrete yet, merely the general gist. I stressed that my plan was to apply science to this field in order to find out what works and what doesn’t; what is safe and what isn’t. Science, I pointed out, generates progress through asking critical questions and through testing hypotheses. Alternative medicine would either be shown by good science to be of value, or it would turn out to be little more than a passing fad. The endowment of the Laing chair represented an important mile-stone on the way towards the impartial evaluation of alternative medicine, and surely this would be in the best interest of all parties concerned.

To me, all this seemed an entirely reasonable approach, particularly as it merely reiterated what I had just published in an editorial for The Lancet entitled “Scrutinizing the Alternatives”.

My audience, however, was not impressed. When I had finished, there was a stunned, embarrassed silence. Finally someone shouted angrily from the back row: “How did they dare to appoint a doctor to this chair?” I was startled by this question and did not quite understand. What had prompted this reaction? What did this audience expect? Did they think my qualifications were not good enough? Why were they upset by the appointment of a doctor? Who else, in their view, might be better equipped to conduct medical research?

It wasn’t until weeks later that it dawned on me: they had been waiting for someone with a strong commitment to the promotion of alternative medicine. Such a commitment could only come from an alternative practitioner. A doctor personified the establishment, and “alternative” foremost symbolized “anti-establishment”. My little speech had upset them because it confirmed their worst fears of being annexed by “the establishment”. These enthusiasts had hoped for a believer from their own ranks and certainly not for a doctor-scientist to be appointed to the world’s first chair of complementary medicine. They had expected that Exeter University would lend its support to their commercial and ideological interests; they had little understanding of the concept that universities should not be in the business of promoting anything other than high standards.

Even today, after having given well over 600 lectures on the topic of alternative medicine, and after coming on the receiving end of ever more hostile attacks, aggressive questions and personal insults, this particular episode is still etched deeply into my memory. In a very real way, it set the scene for the two decades to come: the endless conflicts between my agenda of testing alternative medicine scientifically and the fervent aspirations of enthusiasts to promote alternative medicine uncritically. That our positions would prove mutually incompatible had been predictable from the very start. The writing had been on the wall—but it took me a while to be able to fully understand the message.

Iyengar Yoga, named after and developed by B. K. S. Iyengar, is a form of Hatha Yoga that has an emphasis on detail, precision and alignment in the performance of posture (asana) and breath control (pranayama). The development of strength, mobility and stability is gained through the asanas.

B.K.S. Iyengar has systematised over 200 classical yoga poses and 14 different types of Pranayama (with variations of many of them) ranging from the basic to advanced. This helps ensure that students progress gradually by moving from simple poses to more complex ones and develop their mind, body and spirit step by step.

Iyengar Yoga often makes use of props, such as belts, blocks, and blankets, as aids in performing asanas (postures). The props enable students to perform the asanas correctly, minimising the risk of injury or strain, and making the postures accessible to both young and old.

Sounds interesting? But does it work?

The objective of this recent systematic review was to conduct a systematic review of the existing research on Iyengar yoga for relieving back and neck pain. The authors conducted extensive literature searches and found 6 RCTs that met the inclusion criteria.

The difference between the groups on the post-intervention pain or functional disability intensity assessment was, in all 6 studies, favouring the yoga group, which projected a decrease in back and neck pain.

The authors concluded that Iyengar yoga is an effective means for both back and neck pain in comparison to control groups. This systematic review found strong evidence for short-term effectiveness, but little evidence for long-term effectiveness of yoga for chronic spine pain in the patient-centered outcomes.

So, if we can trust this evidence (I would not call the evidence ‘strong), we have yet another treatment that might be effective for acute back and neck pain. The trouble, I fear, is not that we have too few such treatments, the trouble seems to be that we have too many of them. They all seem similarly effective, and I cannot help but wonder whether, in fact, they are all similarly ineffective.

Regardless of the answer to this troubling question, I feel the need to re-state what I have written many times before: FOR A CONDITION WITH A MULTITUDE OF ALLEGEDLY EFFECTIVE THERAPIES, IT MIGHT BE BEST TO CHOSE THE ONE THAT IS SAFEST AND CHEAPEST.
