The science of Chiropractic and integrative medicine offers patients a complementary or alternative approach to the conventional health care methods of drugs and surgery. Chiropractic physicians embrace the entire person and implement conservative healing methods to enhance and maintain the body's own healing processes. Chiropractic physicians recognize several factors which can impact upon human physiology, among which are biomechanical dysfunction, posture, motion, nutritional status, exercise, stress, genetics, trauma, and microorganisms. Chiropractic physicians strive to correct these and other dysfunctions through the use of manual and natural means whenever possible. However, when situations arise that are outside the chiropractic physician's scope of practice, other practitioners and physicians are utilized.
