Talk:Rotator cuff

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. Away in which direction -- forwards or backwards? And aren't different muscles used if the elbow is at your side instead of level with the shoulder (as in the diagram? (I don't know, and the article does not make it clear.)

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. —Preceding unsigned comment added by 86.154.125.219 (talk) 12:04, 31 October 2010 (UTC)

Rotor Cuff / Rotator Cuff
The University of Cambridge teach Rotator Cuff as the correct terminology, so perhaps not a layman's term. —Preceding unsigned comment added by 131.111.233.176 (talk) 20:51, 12 November 2010 (UTC)

Description of position of upper arm and forearm so unclear
"Sit perpendicular to the dumbell with arm flexed at 90 degrees at the elbow, and the forearm resting parallel on the dumbbell." What on earth does that mean? How do you "sit perpendicular to the dumbbell"? This is too surreal for words. Anybody here who has ever written position descriptions as captions for fitness illustrations? "the forearm resting parallel on the dumbbell." Where is the dumbbell in this description? Why anchor everything to the dumbbell? A good description would start with the position of the upper body, the position of the upper arm relative to the upper body, elbow flexed at 90º, and position of the forearm relative to the upper body. Then we know where the hand is and of course where the dumbbell is. But making the dumbbell the focal point of the description is simply the wrong approach, and impossible to visualize.--ROO BOOKAROO (talk) 13:33, 28 July 2013 (UTC)

Subscapularis is internal, not external rotator

Whole section about exercises is full of glaring mistakes. It is obvious it was written by someone without correct theoretical knowledge, let alone practical. Maybe it would be best to remove it completely and add links to competent sources.
