This is a convenient claim made by critics who have chosen to overlook convincing evidence to the contrary.
The placebo effect depends on the power of suggestion. Yet chiropractic results have been enjoyed by newborns, infants, pets that have been hit by cars, and others for whom the power of suggestion isn’t possible!
Plus, there are alterations to a patient’s spine from chiropractic care. Many see dramatic changes when they compare X-ray views taken before and after a period of care. Other tests show improved range of motion and flexibility.
There’s no question that the power of suggestion can be an important ally in the healing process. However, it can’t begin to explain the millions of patients who have been helped with chiropractic care.
