Treasurer, CBP® Nonprofit, Inc.

 

            Dr. Sang Harrison attended the University of Delaware and Life Chiropractic College in Atlanta, graduating in 1983. She interned with Dr. Don Harrison in Sunnyvale, California in 1983 and practiced in Fremont, California from 1984 to 1986, when she and Don were married and moved to Wyoming. She has been the financial officer for CBP®, Nonprofit since 1986. She has drawn all the skeletal drawings in the CBP® Technique textbooks. She is the co-author of 10 published, accepted, or in review research papers in the Index Medicus.

In a short period of time, CBP® Nonprofit, Inc has raised 50% of the funds needed to support the research agenda of Dr. Chris Colloca and Dr. Tony Keller (Dept Mechanical Engineering at Univ Vermont) for 2001-2002. Drs. Colloca and Keller have already been working hard this summer with four papers ready to submit to scientific journals (Spine, European Spine Journal, Clinical Biomechanics, JMPT). See the items numbered 62-65 below.

           

With the acceptance of CBP® research projects at the European Spine Journal and the Archives of Physical Medicine and Rehabilitation, CBP® research has now appeared in a wide variety of Index Medicus journals, including Spine,4 Journal of Spinal Disorders,2 Clinical Biomechanics,3 Journal of Orthopedic Research,1 European Spine Journal,2 Archives of Physical Medicine and Rehabilitation,1 and JMPT.31 At present, we have six papers in press and two more in review and soon we can add the four papers that will be in review authored by Drs. Colloca and Keller.

            In the past, CBP® research has been spinal displacement in nature, but now the neurology areas researched by Drs. Colloca and Keller will make CBP®’s research one of the few places in chiropractic where subluxation is actually being investigated. Compared to the big budgets of some chiropractic college research departments, CBP® has produced high quality research on a very small annual budget.

            We are getting close to finishing up the three additional clinical control trials at Dr. Deed’s office in Elko, Nevada. Also, Don Meyer, DC has just finished a cohort study at his office. With the three CBP® clinical control trials already published/in press/in review, we will soon have seven clinical studies on CBP® methods. We had nine excellent Case Studies presented at our Annual seminar in Las Vegas on the last weekend in September. Dr. Deed will be working with these DCs to get their studies in the proper JMPT format for submission.
