Actually, a good deal of the ART therapy is for surrounding and affected muscle groups... psoas, hamstrings, adductors, abs etc. However, during the ART therapy around my abs, it caused some irritation of my incision. But my ART specialist speculated that it broke up some scar tissue around the incision. Before that it was really tight and I had a really hard ridge around the incision. That is now gone and my abs have loosened up considerably. Don't confuse ART therapy with mobilization of the incision. I was instructed to massage around the incision myself. And to be honest, I don't know if massaging around the incision itself a waste of time. ART therapy, as I understand it, is to remove what they call "adhesions" on muscles which have been overworked or stressed.
