"I wish that all chiropractors could take in this basic principle of our science-that too much or not enough energy is disease". D.D. Palmer
Today the modern chiropractor determines where there is nerve interference through palpation, instrumentation, x-ray, and muscle testing. During the adjustment the area of nerve interference is released. Innate or the body's own healing ability is released and healing begins. Innate finishes what the Chiropractor begins. There is an emphasis in Chiropractic towards finding the cause of disease rather than treating just the symptoms. Taking medication can cover up the problem but not necessarily cure it.
The chiropractor also takes into account what spinal nerves could be responsible for certain ailment using nerve charts.
