By choice, chiropractors do not use drugs or surgery and instead utilize natural approaches to allow the body to heal. Chiropractors treat primarily the spine and its attachments to restore function and health. They are facilitators of health and utilize a variety of approaches, including adjustments, physiotherapy, exercises, nutritional recommendations, orthotics and daily living modifications. There are roughly 70,000 doctors of chiropractic in the U.S. who are concerned with the diagnosis, treatment and prevention of many disorders of the body. They treat a variety of conditions, ranging from back and neck pain to shoulder, hand, or feet disorders. Doctors of chiropractic are fully accredited and licensed in every state and have become well-accepted as complimentary healthcare providers.
