This is so not a neuro thing, but I found myself doing it today in my neuro OT. So you’ll want to pay attention to this. The scapula is the shoulder-blade. Do you ever feel like your shoulder-blade pops out a little too much? I feel that way all the time. That’s what PTs call scapular winging. Press against a wall like the lady is doing in this picture and if your shoulder-blade sticks way out that’s scapular winging. The muscle that controls this is called the serratus anterior. So in order to stop your scapula from winging get this muscle strong by doing ceiling punches, push-up plus, and this thing. And get your rotator cuff strong. The reason my scapula winged out during OT is because I was concentrating so hard on what I was doing with hands I was paying no attention whatsoever to my backside. When I kinda scanned my body I realized that my shoulder-blade was popped out so I guess I have a weak serratus anterior.
