It's only legit ART if they hold down trigger points and put that area through range of motion. So deep tissue is just a harder back rub while ART they work out the kinks through putting the area through a range of motion. Gratson is done with little tools to break up tissue damage and restore range of motion in the area and speed up recovery. Deep tissue feels good but is pretty useless as far as changes in tissue quality, but if feels damn good and people get a lot out of that.
I've only had two sessions of Gratson. Sometime last year I had two workouts where I had terrible pain in my right knee at the bottom of my squat, was really worried and didn't want to fuck around so I went right to my chiro. Did two really painful gratson sessions and some electrotherapy in the area and I've never felt the pain again. Well worth my $75. I couldn't imagine having Gratson done on a rotator cuff or something like that, or even worse inside the armpit.
My ART therapist was legit fursure. She told me she acutally incorporate ART, Chiro, and Gratson. She mainly did ART and Chiro on me today. Didn't feel much pain when she was working on my lower back but damn, I nearly cried when she was working on my right shoulder along the armpit and on the rotator cuff which it has a chronic injury. I'm going to see her next week. She prescribed me 2 days of rest and icing so no lifting until Friday. I wonder how much scar tissue would she had broke up just in 1 or 2 sessions?
