Doctors of Chiropractic (DCs) are the public's first choice of doctors for treatment using manipulation. A Summer, 1994 study by the respected health care research organization Louis Harris & Associates confirms this as a fact. This nation-wide survey reveals that nearly one-half of the general public and six in ten of those who sought professional care for a back problem in the recent past regard DCs as most skilled in the use of spinal manipulation. And the majority of those who visited other doctors for a back problem also consider DCs more skilled in the use of manipulation than their medical or osteopathic doctor. The DC's clinical expertise is derived from his/her training and the clinical experience gained from spending over 85% of his/her daily practice in the differential diagnosis of the patient's complaint and the management of neuromusculoskeletal (NMS) disorders. The DC's training and experience enable him/her to identify those health problems that are most likely to be responsive to chiropractic management and to administer the appropriate treatment personally, safely and effectively.
