The body forms scar tissue as a natural response to trauma when the skin is lacerated or punctured either by accident or purposefully ie. surgery. Collagen being laid down during the repair process results in a thickened, fibrous mass which can impede proper circulation of blood, congests lymph flow, and can even impact range of motion.
I first learned this scar release as part of Bowen. Shortly after that I received an email from Alastair McLoughlin the creator of the technique stating that it was now recognized by NCBTMB as it's own technique. If I wanted, I could take a test, do case studies and become certified. It has been exciting to be on the ground floor as he builds MSTR.
