Simon Singh sued and silenced; Svetlana and Steinberg's speech surmounts suppression
Science writer Simon Singh (author of The Code Book on yesterday’s list of science books) is a columnist for The Guardian, for which he wrote a column critical of chiropractic titled “Beware the spinal trap.” The British Chiropractic Association sued him for the column, and it was withdrawn from the Guardian’s website. Svetlana Pertsovich has posted the offending column from Internet cache on her website in Russia, James Steinberg has posted it at his blog, and I’ve included it below. UK libel law is still in need of reform. Beware the spinal trap Some practitioners claim it is a cure-all but research suggests chiropractic therapy can be lethal Simon Singh The Guardian, Saturday April 19 2008 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 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. · Simon Singh is the co-author of Trick or Treatment? Alternative Medicine on Trial www.simonsingh.net UPDATE: The part about chiropractic-induced stroke is of interest to me, as I had once heard of a case of chiropractic manipulation leading to blindness. When I mentioned it at a dinner of skeptics in Tempe, Arizona in 1987 that included James Randi and Jim Lowell of the National Council Against Health Fraud, both of them suggested that this was impossible because the optic nerves don’t come anywhere near the spine. But nobody at the table (including me) thought about the possibility of spinal manipulation inducing a stroke causing damage to the visual system. This article from a chiropractic journal discusses cases of visual loss as a result of spinal surgery as a sort of tu quoque defense of chiropractic for similar problems, citing this article: Myers M, Hamilton S, Bogosian A, Smith C, Wagner T Visual loss as a complication of spine surgery. Spine June 15, 1997;22(12). So perhaps my remark from 21 years ago is vindicated? UPDATE (November 4, 2009): Simon Singh gave an overview and update on his case on June 3. Simon Singh fought against the libel claim despite the state of UK law, and has successfully won the right to appeal in October. UPDATE (April 16, 2010): Simon Singh won his appeal, and the BCA dropped their suit.
