"The dilemma that emerges seems clear: informed consent compels chiropractors to tell neck pain patients firstly that the benefit of chiropractic spinal manipulation is uncertain, secondly that its risks are not negligible, and thirdly that other therapeutic options are not associated with harm. Such information is likely to deter patients from choosing chiropractic treatment. Thus, informed consent can work against the financial interests of CM (Complementary Medicine) practitioners, most of who are privately paid by their patients."
