   ABC’s “Good Morning America” had reported on a University of Chicago study that found a possible connection between chiropractic cervical manipulation and a decrease in blood pressure.

   The study, published in the Journal of Human Hypertension, reported that patients who received chiropractic adjustments saw their blood pressure drop an average of 17 points – a dip that usually requires two blood pressure medications to achieve.

   The study does have its limitations, however, including its small sample size. In the original study, only 50 patients were treated. A larger study has been commissioned.

   During the “Good Morning America” segment, which aired in late march, ABC news medical editor Tim Johnson, MD, said, “This [research] catches our attention because of a significant drop in blood pressure. It absolutely deserves more study.
