Hi Tim,
Sorry for the late response. That's a great question. The BFST is a unique product possessing much proprietary information. We have worked hard at improving upon existing technologies and have created a product that is by and far more effective at healing soft tissue.
What I can say is that the BFST is a form of Diathermy that uses electromagnetic energy to stimulate blood flow within deep soft tissue. I have copied in below a link to a research paper written about electromagnetic energy therapy. While this paper does not explain the BFST in full, differs on some aspects altogether and lacks specifics with regards to power density, the research still does touch upon many of the same attributes. The paper gives a brief overview of electromagnetic energy therapy as well as case studies. Our testimonials page is a great resource to see how people have benefited from our products specifically, I highly recommend taking a look at that as well.
As a Customer Service Advisor my main focus is on helping our customers get the best out of our products. However we can definitely appreciate that our customers are in pain, possibly unable to work or compete athletically and are looking for a little more information before giving the products a trial (with our 30 day return policy). For this reason we will be updating this section with research topics and papers periodically and more than welcome any questions.
