Chiropractic was developed by Daniel David Palmer, a self-taught healer in Davenport, Iowa. Palmer wanted to find a cure for disease and illness that did not use drugs. He studied the structure of the spine and the ancient art of moving the body with the hands (manipulation). Palmer started the Palmer School of Chiropractic, which still exists today.
One of the most common concerns about the neck that is not especially worrisome: signs of “wear and tear” on the cervical spine, arthritis, and degenerative disc disease, as revealed by x-ray, CT scans, and MRI. Many people who have clear signs of arthritic degeneration in their spines will never have any symptoms, or only minor, and/or not for a long time.10 For instance, about 50% of fortysomethings have clinically silent disk bulges, and even at age 20 there’s a surprising amount of spinal arthritis. The seriousness of these signs is routinely overestimated by patients and healthcare professionals alike.11
Licensure takes place at the state level under specific state laws. Licensing and the scope of practice may differ from state to state. Most states require that chiropractors complete the National Chiropractic Board examination before they get their license. Some states also require chiropractors to pass a state examination. All states recognize training from chiropractic schools accredited by the Council of Chiropractic Education (CCE).
Maruyama et al: “All but one patient [of seven] with migraine considered the pain to be unique and unusual compared with previously experienced headache or neck pain episodes. Nevertheless, pain was often interpreted initially as migraine or musculoskeletal in nature by the patient or the treating doctor.” Arnold et al: “Pain was different from earlier episodes in all but one case [of 20].” BACK TO TEXT

Chiropractors use hands-on spinal manipulation and other alternative treatments, the theory being that proper alignment of the body's musculoskeletal structure, particularly the spine, will enable the body to heal itself without surgery or medication. Manipulation is used to restore mobility to joints restricted by tissue injury caused by a traumatic event, such as falling, or repetitive stress, such as sitting without proper back support.
