A Chicago-area study of patients with a misaligned Atlas vertebra (located high in the neck) and high blood pressure showed that after a one-time specialized chiropractic adjustment, blood pressure decreased significantly. The research was conducted by Dr. Marshall Dickholtz, Dr. George Bakris and Dr. Bruce Bell.
