Subluxation-based chiropractic care is sustained more by faith than by facts
Much of what is discussed in this article has been said before in previous articles I have written for Science-Based Medicine. But since the audience for SBM has greatly increased over the past few years, some subject matter should be repeated for the new readers and researchers coming to this site for reliable information on health care.
Many consumers now search SBM for articles dealing with controversial alternative treatment methods that have been shown to be ineffective or to be loaded with fraud and quackery. Chiropractic in particular continues to be problematic for its failure to renounce the scientifically indefensible, nonfalsifiable subluxation theory that defines the profession as a whole. A review of chiropractic web sites reveals that many chiropractors continue to base their treatment methods on subluxation theory, encompassing a broad scope of health problems. Some chiropractors are now including use of “functional medicine” which uses “natural tools” to treat diabetes, thyroid disease, neuropathy, and other diseases best treated by conventional medical care. Most alarming of all is the treatment of infants and children by “pediatric chiropractors.” Chiropractors are being certified in 10 different specialties, including a diplomate in Diagnosis and Internal Disorders.
As long as chiropractic is licensed as a health-care profession based on subluxation theory or some other unscientific approach, it will continue to be subjected to scrutiny and criticism by the science-based community. It is, in fact, the moral and ethical responsibility of science-based practitioners to oppose any form of unscientific health care, wherever it might exist, separating sense from nonsense without being influenced by politics, special interest, pseudoscience, or belief systems.
In 2011, chiropractor J.C. Smith published The Medical War Against Chiropractors: The Untold Story from Persecution to Vindication. He promises an exposé comparable to Harriet Beecher Stowe’s exposé of slavery in Uncle Tom’s Cabin. His thesis is that the AMA waged a shameless attack on competition, motivated only by money. I think the reality is closer to what he quoted from Dr. Thomas Ballantine, Harvard Medical School:
The confrontation between medicine and chiropractic is not a struggle between two professions. Rather it is more in the nature of an effort by an informed group of individuals to protect the public from fraudulent health claims and practices.
The book is self-published, long-winded, repetitive, and flawed. It is a vicious screed crammed with bias, half-truths, insulting language, and innumerable references to Nazis and racial prejudice. In my opinion, Smith not only fails to make his case but degrades chiropractic.
There is a very good chance that you will feel worse after seeing a chiropractor.
According to a new systematic review, serious complications of spinal manipulation are rare, but 33-60% of patients experience milder short-term adverse effects such as increased pain, radiation of pain, headaches, vertigo and even loss of consciousness. The study, published in the journal Spine, involved searching PubMed and the Cochrane Library for the years 1966 to 2007. They identified additional studies by hand searching. They looked for all articles that reported adverse effects associated with chiropractic irrespective of type of design. They omitted any reports where patients had underlying diseases (osteogenesis imperfecta, expansive vertebral hemangioma, osteoporotic fracture, etc.) that predisposed them to complications with manipulation.
They found 46 pertinent studies:
- One randomized controlled trial
- Two case-control studies
- Six prospective studies
- Twelve surveys
- Three retrospective studies
- 115 case reports
They recognized that “the heterogeneity of the study designs did not allow conducting a formal meta-analysis.” But they did the best they could to make sense out of what they found. (more…)
