My Cousin is a senior physical therapy consultant however he is in Glasgow Scotland, I have a contact at a hospital in Boston MA, if you would be ok with going there for a visit? I can ask them about physical therapy shadowing and short internships and will do my best to update on here, Boston really is a nice city and you're not far away, a few hours on the train or even quicker to fly to Boston Logan..
There's lots to see and do there and the people are nice,the food is great too (am sure you've been already, I stayed there for a while myself)
Students like yourselves usually need to take the initiative to find shadowing opportunities.
Just go to a local office or to an office of someone you know, or even your MD to ask him, her.
Say something like you are considering a career in PT , and wants to see what qualities are called for,and that you would greatly appreciate having the opportunity to shadow one of their PTs.
