European Spine Journal Publishes PosturePrint® Study

by Deed E. Harrison, DC

After his undergraduate pre-chiropractic courses at the University of Utah, Dr. Deed Harrison graduated from Life-West in 1996. He is co-author of more than 50 peer-reviewed, indexed, research articles. These include 32 in JMPT, 3 in Chiropractic Technique, and 15 at major Index Medicus journals. He is a Reviewer for an Index Medicus Orthopaedic journal. He is a certified instructor for CBP® Seminars, has written three new CBP® text books, and is Vice-President of CBP® Nonprofit, Inc. He has a private practice in Elko, Nevada.

In January 2006, the Editor of the European Spine Journal notified us that one of our projects on the PosturePrint® was accepted for publication. This manuscript is entitled, “Validation of a Computer Analysis to Determine 3-D Rotations and Translations of the Rib Cage in Upright Posture from Three 2-D Digital Images,” by Harrison DE, Janik TJ, Cailliet R, Harrison DD, Normand MC, Perron DL, Ferrantelli JR.

           This project was completed on a mannequin thoracic cage at the University of Quebec a Trois Rivieres in December 2004.

           In the Biomechanics laboratory, the mannequin positions were precisely measured before three PhDs took 204 photographs (68 different positions). The photographs were processed through the PosturePrint® computer program and the differences from measured positions of the mannequin to PosturePrint® calculations were reported as measured errors. The results showed that the PosturePrint® computerized postural analysis was extremely accurate for a simple photographic method.

           Critics (Triano), at the recent ACC-RAC Conference (March 2006 in Washington, DC), complained that we did not use multiple cameras at orthogonal positions with expensive computer code analysis (such as the $250,000 system at Health South). PosturePrint® uses one camera, one wall grid, and some cheap anatomical markers. We responded with the facts that (1) we obtained very close to similar accuracy to those expensive systems (1.5 degrees for rotation angles and 1.5 mm for translations), (2) our method is very inexpensive (PosturePrint® cost the User $30/use) compared to orthogonal cameras systems used at University laboratories (several hundred thousand dollars = what DC could buy one?), (3) our method showed high reliability even though the subject is moved to new locations during photography (left lateral, AP, right lateral), (4) our method can fit into a Doctor’s exam room and thus is very convenient for clinical use, and (5) our method supplies the Doctor and patient with a very accurate but simple to read/understand Report of Findings.

           The accuracy of postural analysis by the PosturePrint® will allow us to perform future clinical studies with this computer analysis.
