"Chiropractic is a controversial health care system that originated in the United States in 1895. The National Council Against
Health Fraud (NCAHF) finds it remarkable that the chiropractic profession has existed for a century without having made a
single notable contribution to the world's body of knowledge in the health sciences. The reason for this failure can be found in
its origins and in the continued presence of antiscience attitudes. This includes the fields of the care and prevention of back pain
and the value of spinal manipulative therapy (SMT), the areas in which chiropractic has dominated the health care services
marketplace. Recent pronouncements on the value of manipulative therapy for back pain have involved medical research, not
work done by doctors of chiropractic (DCs). DC publicists have been quick to grab the credit for these findings for marketing
purposes, but deserve little credit. Some research projects are now under way, but chiropractic still does not play a significant
role in researching the causes and treatment of the human ailments from which it derives most of its income."
