1- The mnemonic for the muscles is: SITS
2- We will start with ABDuction and finish with ADDuction
3- The vowels in English can be remembered by AEEIou ( shout to remember better :P )
4- Now just match letters from the 2 mnemonics in the same order they are written in
as you can see in the table:
So S goes with A...I goes with E...T goes with E and the last S goes with I.
Never forget the action of Rotator Cuff muscles again :)
