Why Do You Have Shoulder Pain?
The shoulder blade has 17 muscles that attach to it. Imagine trying to organize and outing for 17 people. Not only do you have to get everyone to agree on where to meet, you need them to all get there at a certain pace and certain speed. Similarly, when your shoulder blade moves in any direction, 17 muscles have to coordinate and adjust to give you whatever movement your brain wants it to do.
So if ONE of them is off, due to injury or faulty movement pattern, it throws the whole team off. And that’s only one. Most of the time multiple scapular muscles are not working properly so your body ends up using other adjacent muscle groups to help with the movement. Before you know, you develop a compensation pattern that your body recognizes as the new normal and it wears out your rotator cuff over time.
Bottom line is, your shoulder health is essentially dependent on how well your shoulder blades move.
