CARMICHAEL, Calif.--(BUSINESS WIRE)--A Chicago-area study of 50 individuals with misaligned Atlas vertebrae (located high in the neck) documents reduced blood pressure following one specialized chiropractic adjustment and continued results after eight weeks. The Foundation for Chiropractic Progress, a not-for-profit organization dedicated to increasing public awareness of the benefits of chiropractic, points out that these results, as published in the March 2, 2007 online issue of the Journal of Human Hypertension, are two times greater than provided by a blood-pressure drug.
