What did (s)he do there? (Not a native speaker if that matters).
Not a native speaker either so I may be wrong in this assessment, but a physio is someone who also gives therapeutic massages when needed. Hence, rubbing shoulders.

(Computer programmers like me who spend a long time at the keyboard often visit a physio to get our shoulders manipulated and rubbed to relieve built up tension).
