There is now a lot of evidence showing that more than half of patients suffer from mild to moderate adverse effects after consulting a chiropractor. They are mostly local and referred pain that usually last two to three days. Chiropractors often state that these are necessary steps to improve. Although doctors use this series of codes to indicate traumatic vertebral dislocation (a contraindication for manipulation), chiropractors often use these codes to indicate manipulable vertebral subluxation.
They then estimated the total number of neck manipulations performed by chiropractors during the same period from survey responses, comparing them with insurance reimbursement data. They surveyed all members of the Danish Chiropractic Association and compared member reports on stroke cases with published cases, official complaints, and insurance data. Spinal manipulation (MS), as performed by chiropractors, is an effective option for treating certain types of spinal pain and some headaches. Since chiropractors perform between 80 and 90 percent of the spinal cord manipulations performed in the United States, and this company insures approximately half of the professionals in the US.
In the US, this malpractice insurer is a good source of statistics on this topic. The author estimated that Canadian chiropractors performed at least 50,000,000 cervical manipulations during that period. As WebMD states, “Chiropractors use practical spinal manipulation and other alternative treatments, with the theory that proper alignment of the body's musculoskeletal structure, particularly the spine, will allow the body to heal on its own without surgery or medication. You could even visit the chiropractor for more gentle manual or traction therapy, which involves stretching or movements that are less aggressive and more controlled.
Wade Smith, a neurologist and one of the authors of a 2003 study that found that chiropractic manipulation is an independent risk factor for strokes, said that chiropractors should warn people, even if the risk is small. However, one of the techniques used by chiropractors, called cervical neck manipulation or “neck cracking,” has raised concerns that it could cause serious harm. During that period, there were about 110 million visits to the chiropractor's office in California and between 33 and 50 million neck adjustments. Experts say the chiropractor who treated her could have been too aggressive, leading to ruptured arteries.
Less conservative treatments, such as neck surgery, are also commonly used for conditions very similar to those that chiropractors treat by manipulating the spine. Unfortunately, there have been cases where patients have suffered serious injuries after consulting a chiropractor. Instead, they say, a visit to a chiropractor is usually the result of an arterial dissection, not the cause of it. Beliveau, who had been to the chiropractor because of persistent back pain caused by a car accident, said he wouldn't have done the treatment either if he had known.
