I just wanted to clarify.

As far as I know, Range of Motion done yourself under the instruction of your doctor should be done after surgery yes. Physical therapy after surgery for the continued treatment of TOS may be helpful, yes of course.

But, do you need physical therapy in response to the surgery itself? No, as far as I know.

Further, no physical therapy should be done with someone that has not treated TOS before. Finding a good PT that knows TOS is key regardless of when the PT is done.
