Dr. Perron presently is Vice President of Business Development for Biotonix, a technology company in Montreal, Quebec, Canada. She received her DC degree from Palmer College in 1985. Before deciding to help advance Biotonix‚s entry into healthcare markets, she had a high volume chiropractic practice for 15 years. For the past 8 years, Dr. Perron has been a member of the Board of Directors of Somiper Inc., which owns assets in the biotechnology, pulp and paper and aviation industries. She has lectured on Postural analysis and protocols of care at many different chiropractic colleges and universities, including Parker, CMCC, UQTR, as well as medical institutions such as Stanford, and University of Pittsburgh Medical Center. Since 2002, Dr Perron has also been involved with lecturing to Chiropractors and healthcare practitioners in Japan.

Establishing for Chiropractors and healthcare practitioners a scientifically sound baseline tool to measure postural deviations, track changes, and prescribe corrective exercises has been major feat. We are pleased today to see Doctors and Patients benefit from the science of CBP® through the PosturePrint™ with their personalized exercise programs, postural monitoring along with continued chiropractic care.
When patients understand what is wrong with them and why they need postural correction, they are more likely to continue chiropractic care. PosturePrint™ has been shown to increase patient retention and increase the efficiency of providing quality personalized care for patients. PosturePrint™ is committed to providing Doctors with the most scientific and easy to use clinical tool to help DCs help their patients.
Most of you know that we have already performed validity studies on mannequins with the PosturePrint™ at the University of Quebec a Trois Rivieres in late 2004. Once the reliability and validity of the PosturePrint™ was established on mannequins, (the results came out more accurate than we dreamed), we then designed the next step in a reliability study. This research on human subjects is to further substantiate, not only the intra and inter-examiner marker placement reliability, but the reproducibility of the whole process using PosturePrint™.
For our reliability study, in November 2005, Dr. Don Harrison (Wyoming), Dr. Joe Ferrantelli (Florida), Dr. Marin Wendell (Nevada), and I (Denise Perron, DC, Montreal, Canada) traveled to the University of Quebec a Trois Rivieres to perform a PosturePrint™ Reliability study with Martin Normand, PhD, DC, Professor at UQTR. Dr. Normand and Dr. Harrison had previously written a research proposal and IRB for using student subjects for our reliability project. After the Ethics committee at the UQTR approved our project, Dr. Normand arranged to have 40+ volunteers and for permission to use the lab at the Chiropractic Division of UQTR.
While I obtained personal data from each subject, Drs. Marin Wendell, Joe Ferrantelli, and Martin Normand placed markers and took three photographs of each volunteer subject. With a one day delay, this process was repeated. This will allow for three sets of Intra- and Inter-Examiner Reliability data on the PosturePrint™ system.
Those not familiar with research protocol believe that we should have done PosturePrint™ research on human subjects first, but it is a waste of money to do reliability studies if one’s evaluation tool is not valid/accurate. Thus, first we performed validity studies on mannequins with the PosturePrint™ at the University of Quebec a Trois Rivieres last year. When the results came out more accurate than we dreamed, we designed this reliability study.
When the data analysis is finished, this present reliability project will complete our preliminary investigations into the validity and reliability of the PosturePrint™ system, which is used to measure rotations and translations of the head, rib cage, and pelvis in 3-D. We will then proceed with the Posture and Health study planned with the ICA. You can contact me, Dr. Denise Perron at perrond@biotonix.com or Susan Bourck at bourcks@biotonix.com.
