Why are you giving me Shoulder Blade exercises if I have Shoulder pain–Part 3 Olympia WA

The video demonstrated below, by an orthopedic surgeon, shows the mechanics of why shoulder impingement happens with the tendons.

See the small space between the ball acromium? That is where the impingement happens. Making sure the supraspinatus tendon, which pushes the ball down as the arm bone is lifted by the deltoid, is working well is a big part of the picture of shoulder healthy function. BUT….if you raise the shoulder blade UP by STRENGTHENING the muscles which lift it up, (such as serratus anterior) and STRETCH muscles which PULL it down (such as latissimus dorsi) you can gain more space, which puts less pressure and pinch on the supraspinatus tendon.
