During undergrad I first heard of IASTM, from a friend and former classmate that was attending chiropractic college; he talked about Gua Sha, Graston and SASTM. He went into their use and cost (how he was going to try to even pay for it). He sparked my curiosity and I started to look into IASTM, particularly the major marketers (Graston, SASTM, and ASTYM) and how it was theorized to work. Also, during my extremities orthopedic class in DPT, an adjunct clinical professor showed us a tool that he had been using. This was my first hands on exposure to an instrument. He also talked about some of the IASTM tools on the market. Most of us were interested in the tools but not the price. I joked to a couple of classmates that day in class that I could make them less expensively and they said they would buy one if I could pull it off.

I started talking with the Machine Shop staff in the Engineering Department at the University at Buffalo. Since I was a student I had access to the university’s facilities to do the project at a substantial savings. I learned to use CAD software to save money by doing the designing and prototyping myself. Once I had the design, I also figured out the whole machining process and related costs. It was pitched to my current and former classmates getting enough interest to move forward. About 75% of the class pre-ordered to fund the project and the first run of Fibroblasters was made in late Fall ’09 (entire project was not-for-profit).

As with all good stories, I have to give a shout out for my mom. She went online to be the first to purchase a Fibroblaster from the website, at retail price no less. She proudly displays it next to the clay knickknacks that were made in elementary school. For the financially strapped graduate student, there is a student discount for those willing to supply me with their advisor’s name, email, contact number, school name and grad date. Once status is verified, they receive a discount via email. Since the start sales have been steady and there has been lot of positive feedback from those who have purchased. The goal of Fibroblaster is to make a quality soft tissue mobilization instrument without the high price tag that is associated with other stainless steel IASTM tools on the market.
