In Arizona chiropractors must pass strict licensing requirements. In addition to the practice of chiropractic medicine, additional certification can be obtained in physiotherapy, and Acupuncture. Also many chiropractic doctors take post graduate training and have additional education. One post graduate training course is called Advanced Practice. Chiropractic Advanced Practice requires and additional nine month of specialized training in the interpretation of blood, urine and hair analysis. These tests help the Advanced Practice chiropractor to determine nutritional needs in a scientific and objective way. They also help the doctor document that his treatment is working through improved measures on the patient's labs. There are specialty programs within chiropractic that are approved by the American Chiropractic Association, Some of the more popular board certifications through the ACA are radiology (the post graduate study of X-rays and MRIs), Orthopedics (the post graduate study or orthopedic joint conditions and their treatment) and Neurology which is the post graduate study of the brain and spinal cord. While chiropractic doctors with these advanced certifications are recognized by the American Chiropractic Association as having a specialized body of knowledge in their field, they are licensed under the Arizona Board of Chiropractic Examiners. Like all chiropractors in the State of Arizona.
