Serratus Anterior MMT
For various shoulder pathologies and movement impairment syndromes, one of the most common contributing factors includes a lack of sufficient scapular upward rotation. This is often due to insufficient activity of the trapezius and serratus anterior muscles. The serratus anterior muscle is capable of providing both a protraction and upward rotation force. It is the upward rotation force that we are wanting to test, however. In my clinical practice thus far, I have seen several different ways of testing the serratus anterior, but it is essential that the upward rotatory force is assessed.
Origin: outer surfaces and superior borders of upper 8-9 ribs
Insertion: costal surface of the medial border of the scapula
Take a look at the video below for how to perform the MMT. How do you test the serratus anterior and what are some ways you like to train the muscle?

Supine punch ups and wall push up plus (push off the wall) are good serrated ant. exercises.

Both exercises are great. In my experience however they are more geared towards protraction. To incorporate the upward rotation provided by the Serratus I often have patients do a foam roll up/down on a wall using their forearms. I find it to be more functional.

I typically start pts with the wall push plus if they can access their SA. If not I will do to the supine punches. To train more functionally I do closed chain wall Ys with resisted banding between the arms.
