              In 1990, Dr. Don Harrison presented the CBP® Nonprofit, Inc Board with a 5 year plan for research. This came about because Drs. Sang and Don Harrison were disappointed in the direction of chiropractic research at that time and decided to do something about it. The CBP® NP Board decided to funnel the majority of its funds into research. It took 3 years (1993) for us to achieve our first publication. This Board decision has resulted in 61 publications, 10 in press, 8 in review, and 11 in preparation for a total of 90 papers from 1993-2003!! Our next major goal is to reach 100 publications in the Index Medicus and we believe that we will reach this goal by the end of 2005.

            For our next 10-year plan, we are moving into more clinical type studies versus the necessary foundation work that our previous 10 years had established. Our 5th and 6th Clinical Control Trials have been finished and submitted; one of which has been accepted with minor revisions and the other one is in review.

            However, we still want to continue our biomechanical studies with Tad Janik, PhD, Chris Colloca, BS, DC, and Tony Keller, PhD. Some of these studies have established/quantified that abnormal posture creates abnormal loading on the spinal tissues.

            At the CBP® NP Annual meeting held this year in Jackson, Wyoming, the CBP® Board voted to fund computerized ROM equipment for Dr. Deed Harrison to use to collect clinical data. The Board also approved a new computer system for Tony Keller, PhD and an Australian project utilizing pigs with Robert Gunzburg, MD, Rob Moore, PhD, Tony Keller, PhD, and Chris Colloca, DC.
