My thoughts on PT is that it can be good or it can be bad..

depends on the therapist.
depends on what your cause or symptoms are.
depends on If the PT does an assessment at beginning of each session, to see how you are doing, if anything got worse or better.
good ones will adjust the "plan" to address issues that arise, by backing off you have increase in pain and only moving forward after no increase in pain or symptoms.

Posture needs to be addressed too. The worse it is the longer it will take to see improvements..

*The standard "cookie cutter" PT plan of pushing most of us into strengthening right away is not good at all.*
We used to have so many posts about the generic PT plans- they might work Ok for people with strains or c spine issues, but not for TOS.

If you are in pain, then pain reliving modalities need to be used first, until pain is way down. Any trigger points need to be resolved also.
And top rib mobilization if applicable. I suffered for months before anyone thought to check mine..


If you have severe clear cut NTOS, PT most likely can't help that much because something is directly impinging/compressing on the nerve somewhere.
