physical therapy for musicians/artists

does anyone know if any of the PT places around here know much about repetitive stress caused by guitar playing and/or drawing and or knitting/crochet? I'm seeing some folks out in boonton (near my work) and they seem pretty sports focused. I told my PT I'd been knitting and I think it's flairing up my shoulder bursitis and he didn't undertand why it would trigger that but a web search tells me it's a common repetitive stress thing for knitters?

I have other reasons for looking for a new PT than just that but I thought if I could find someone who knows more about nerd injuries it's be a nice bonus.
