My name is Mark and am a DPT, CSCS. I wanted an opinion from a T-Nation therapist about IASTM (Graston or ASTYM) and its ability to break up scar tissue. I know foam rolling and other myofascial release techniques won’t break up scar tissue, but other therapists in my field are convinced a tool assisted STM will do the trick. I’m not convinced. Please respond, I would really love to know others opinions or facts.
