Future Projects

by Sanghak O. Harrison, DC

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 also practiced in Evanston, WY from 1986-1992. In 1993, she took over the Harrison CBP® Seminars business. 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.

         

 

 

From the front page article, you will note that we have two out of four of our PosturePrint® research projects accepted for publication. The other two projects are in review at Index Medicus journals. Soon we will start two important projects with the PosturePrint®. The ICA approached us with a project of collecting data on health and posture concomitant to ascertain any posture association with various health conditions or activities of daily living. They asked for 2,000-3,000 subjects. Such a project requires easy data processing and storage, which the Postureprint® provides.

              Additionally, CBP® researchers wish to measure any postural changes pre-post with CBP® Technique methods on large samples of patients from different offices.

              Also we are streamlining our research data collection methods with x-ray digitizing. We have developed PostureRay™ which allows digital images to be analyzed with angles and distances after choosing points on images of x-rays. These images can be from digital photos, scanners, or new digital x-ray equipment.

              We are also working on a whiplash study which preliminarily indicates how much loss of curve occurs after a car accident. We have approximately 50 subjects that had initial x-rays then were subsequently involved in a car accident and a second set of x-rays. Thus, before and after car accident lateral cervical views were available. These were digitized and analyzed.
