I saw a PT a couple of months ago who did a couple of passthroughs on my subscapularis via ART and I got some good feedback and my ROM opened up pretty good for a day or so.  

If a muscle has been gummed up and in spasm for months is it likely to take several sessions to see drastic improvement (like a sticky subscap) or would I likely see full improvement and lasting relief on one session?
