So THAT's what the rotator cuf is.
This is some interesting stuff. A friend ws asking me how you can tear your "rotator cup" so I figured I'd look it up online. Well I certainly know a lot more about the rotator cuff now than I did before. And now that I read this I think I may have actually torn my "rotator cup" before without even knowing what had happened.
The pictures are labelled incorrectly
The 1st exercise is "side lying external rotation", the 2nd exercise is "abduction"..... perhaps the descriptions are just next to the wrong pictures?
Actually the first two pictures are both external rotation, the first "side lying" and the second "standing"; side lying abduction is not shown!! —Preceding unsigned comment added by 12.191.193.147 (talk) 22:59, 24 September 2007 (UTC)
Watch the exercises on DVD
To make sure you do the exercises correctly you can watch them on DVD or even on youtube. I got a DVD that worked great at shoulderrelief.com but I'm sure there are others out there too. It may help make clear where those still pictures are hard to follow. —Preceding unsigned comment added by 72.130.230.200 (talk) 21:12, 6 February 2008 (UTC)
Are we forgetting a few muscles in this phrase?
"Along with the teres major and the deltoid the four muscles of the rotator cuff make up the six scapulohumeral (those that connect to the humerus and scapula) muscles of the human body."
While it's distal attachment is on the radius, Biceps long head very often considered an RC muscle, and the coracobrachialis, while minor, is still in there. Phtyex (talk) 13:02, 19 March 2008 (UTC)
Also the long head of triceps arises from Scapula and the medial and lateral from humerus.So that forms a connection.So added 'acting on gleno humeral joint'.

no description of impingement
I came to this page to learn more about my diagnosis, but there is no description of a rotator cuff impingement. It would be great if someone more knowledgeable than I could add something there. Thanks-- Suzensez (talk) 13:26, 23 March 2008 (UTC)
Supraspinatus does not perform external rotation
In the description of the first exercise used to strengthen the rotator cuff, an exercise involving external rotation is said to activate the supraspinatus. The supraspinatus is responsible for should abduction only, and is not even the prime mover involved in this movement, it merely acts as a synergist. —Preceding unsigned comment added by 128.54.62.115 (talk) 08:49, 21 January 2010 (UTC)
Description of action
On this, and other muscle pages, the descriptions of the action of the muscle are unclear to the layman. For example, abducts the arm where abducts is defined as a movement which draws a limb away from the median (Sagittal) plane of the body. Which of the three planes, and which direction away from the plane? Surely this could refer to any of four movements.
The section with the three exercises is far clearer. Of course, the pictures are a great help.
For a general audience the function of a muscle would be most successfully communicated by describing an exercise or action that uses the muscle.
