Scapula retraction and protraction

[scilearner]

I hope this is the right place to put it.

 

Anyway when I checked wikipedia it says

 

Protraction is the movement of an anatomical part of the body forward (anteriorly)

 

However in the scapula protraction is movement to left and retraction to the right. It is not forward bending. Then I checked some youtube videos and they do the test like wiki. I'm confused!!

 

Thanks

Your ribcage is curved, and your scapula slides along it. Thus, as you move your scapula away from your spine, it'll also slide forward with the curve of your ribs. Reverse the motion to get retraction.
