Simon Singh's Takedown of the Chiropractic Industry: Raw and Unedited

My darlings, I have got something PZ hasn't got: the original Simon Singh article that launched a libel suit over the word "bogus." Thanks to Orac, we can see it in all its original glory:

A while back, I wrote about the grievous miscarriage of justice that occurred to Simon Singh in the form of a ruling against him in the libel suit brought against him by the British Chiropractic Association. Suffice it to say, that the BCA is using the U.K.'s exceedingly plaintiff-friendly libel laws to silence legitimate criticism of the dubious practices of its members. This resulted in a campaign from the British pro-science organization Sense About Science to Keep Libel Laws Out of Science.

Now, I learn that, true to Internet tradition, the attempt to suppress information or punish someone for utilizing his free speech rights is boomeranging, as it nearly always does. Dozens of blogs and websites are reprinting a lawyer-sanitized version of Singh's original article, which lack a couple of sentences, namely the allegedly defamatory sentences plus one other that I can't for the life of me figure out why the lawyers removed. Personally, I don't see the point of using the lawyer-scrubbed version, and here's why. The very point of commenting on this libel case is to point out how outrageously illogical and illiberal Judge Eady's ruling on the meaning of "bogus" in the context of the article is. How can readers know what all the fuss is about if a lawyer-sanitized version of the article is all that they can see?

So read and judge for yourself if Judge Eady made a reasonable ruling. Is this article libelous? I don't think so. The sentences everyone else is excluding are in bold:

Beware the spinal trap

Some practitioners claim it is a cure-all but research suggests chiropractic therapy can be lethal

This is Chiropractic Awareness Week. So let's be aware. How about some awareness that may prevent harm and help you make truly informed choices? First, you might be surprised to know that the founder of chiropractic therapy, Daniel David Palmer, wrote that, "99% of all diseases are caused by displaced vertebrae". In the 1860s, Palmer began to develop his theory that the spine was involved in almost every illness because the spinal cord connects the brain to the rest of the body. Therefore any misalignment could cause a problem in distant parts of the body.

In fact, Palmer's first chiropractic intervention supposedly cured a man who had been profoundly deaf for 17 years. His second treatment was equally strange, because he claimed that he treated a patient with heart trouble by correcting a displaced vertebra.

You might think that modern chiropractors restrict themselves to treating back problems, but in fact they still possess some quite wacky ideas. The fundamentalists argue that they can cure anything. And even the more moderate chiropractors have ideas above their station. The British Chiropractic Association claims that their members can help treat children with colic, sleeping and feeding problems, frequent ear infections, asthma and prolonged crying, even though there is not a jot of evidence. This organisation is the respectable face of the chiropractic profession and yet it happily promotes bogus treatments.

I can confidently label these treatments as bogus [changed to "utter nonsense" in the scrubbed version] because I have co-authored a book about alternative medicine with the world's first professor of complementary medicine, Edzard Ernst. He learned chiropractic techniques himself and used them as a doctor. This is when he began to see the need for some critical evaluation. Among other projects, he examined the evidence from 70 trials exploring the benefits of chiropractic therapy in conditions unrelated to the back. He found no evidence to suggest that chiropractors could treat any such conditions.

But what about chiropractic in the context of treating back problems? Manipulating the spine can cure some problems, but results are mixed. To be fair, conventional approaches, such as physiotherapy, also struggle to treat back problems with any consistency. Nevertheless, conventional therapy is still preferable because of the serious dangers associated with chiropractic.

In 2001, a systematic review of five studies revealed that roughly half of all chiropractic patients experience temporary adverse effects, such as pain, numbness, stiffness, dizziness and headaches. These are relatively minor effects, but the frequency is very high, and this has to be weighed against the limited benefit offered by chiropractors.

More worryingly, the hallmark technique of the chiropractor, known as high-velocity, low-amplitude thrust, carries much more significant risks. This involves pushing joints beyond their natural range of motion by applying a short, sharp force. Although this is a safe procedure for most patients, others can suffer dislocations and fractures.

Worse still, manipulation of the neck can damage the vertebral arteries, which supply blood to the brain. So-called vertebral dissection can ultimately cut off the blood supply, which in turn can lead to a stroke and even death. Because there is usually a delay between the vertebral dissection and the blockage of blood to the brain, the link between chiropractic and strokes went unnoticed for many years. Recently, however, it has been possible to identify cases where spinal manipulation has certainly been the cause of vertebral dissection.

Laurie Mathiason was a 20-year-old Canadian waitress who visited a chiropractor 21 times between 1997 and 1998 to relieve her low-back pain. On her penultimate visit she complained of stiffness in her neck. That evening she began dropping plates at the restaurant, so she returned to the chiropractor. As the chiropractor manipulated her neck, Mathiason began to cry, her eyes started to roll, she foamed at the mouth and her body began to convulse. She was rushed to hospital, slipped into a coma and died three days later. At the inquest, the coroner declared: "Laurie died of a ruptured vertebral artery, which occurred in association with a chiropractic manipulation of the neck."

This case is not unique. In Canada alone there have been several other women who have died after receiving chiropractic therapy, and Professor Ernst has identified about 700 cases of serious complications among the medical literature. This should be a major concern for health officials, particularly as under-reporting will mean that the actual number of cases is much higher.

Bearing all of this in mind, I will leave you with one message for Chiropractic Awareness Week - if spinal manipulation were a drug with such serious adverse effects and so little demonstrable benefit, then it would almost certainly have been taken off the market.
