YES,
Movements by micro movements, the awareness and ability to do anything slow as in Feldenkrais.
It took me 2-3 weeks before my doc of PT started out doing the perscribed trap max/minus strrengthening.
And it took me weeks to get it going.
You say, STRENGTHENING with TOS? Never as I learned the hard way
However, there are conclusive exceptions to the law of TOS.
Our posture is the culprit from doing what we did best in our careers or injured.
The trapezius muscles, cervical spine and shoulder girdle are weakend by the stress.
We have to begin strengthening these muscle areas that came crashing down or all the surgeries in the world will not do anything for us.

Begin laying flat on the floor. The floor is now my bestest friend.
Think Feldenkrais to start with and use micro movements bringing your trapezius muscles towards your spine and down tightening for a few seconds.
Then dor the other side.
You will find one side is easier than another and it it very hard when in pain to begin with.
Let me say 3 months later after my 911 cal and trip to the ER
Everbody comments on my posture.
It feels so good and take the pressure and burning off the muscles.
But as with anything like typing this
You have limits
It's my time to say I'll be back to add more.
