He might want to look into ART (Active Release Techniques). I fucked my Rotator cuff as well, and they told me I needed surgery. I knew that if I get surgery, I would never be the same again. I tried regular physio, it helped, but not all that much. Someone told me about ART, and I'm now pressing 80% of what I use to.
Call 719-473-7000, this will give you an ART licensed physiotherapist in your area.
Btw, this may sound like an ad, but I have no vested interest in this.
Good luck to your friend.
