Scapular Dyskinesis

Stretching: The Truth

I'm planning on a series of articles to update our readers on some of the current concepts in pitcher related injuries and diagnoses that most fans have not heard much about.

We've all had our fill of reading about pitchers with rotator cuff and glenoid labrum tears. There are some interesting trends in sportsmedicine that have lead to changes in exercise programs throughout the majors and minors in an attempt to protect pitchers from a cascade of preventable injuries most fans don't know about.

Diagnoses such as:

GIRD: (Glenohumeral Internal Rotation Deficit...not to be confused with the stomach malady also known as GERD which Cubs fans get from watching too many losses). Pitching (both cocking phase and deceleration phase) leading to a tight or thickened posterior shoulder capsular ligament plus a loose anterior capsule and loss of internal rotation of the shoulder. Extra external rotation of the shoulder develops at the expense of internal rotation.

Scapular Dyskinesia: Shoulder blade weakness with altered kinematics.

Internal Impingement: Thought to be related to posterior shoulder contracture from GIRD with subsequent instability of the shoulder as the humeral head (ball of the shoulder joint) which shifts back/posteriorly and upward/superiorly). This is a different entity from subacromial or rotator cuff impingement which is more common and typically occurs from friction outside the shoulder joint.

...and finally connecting the dots, sorting out how the the injured or weakened shoulder (scapula) leads to severe strain on the elbow and tearing of the Ulnar Collateral Ligament (aka the Tommy John injury).

My attention to this topic started last summer, when  I heard a remarkable interview on XM radio with renown Orthopedic Surgeon, Dr. Craig D. Morgan with hosts Jim Memolo and Rob Dibble. The focus of the interview was Stephen Strasburg's shoulder tightness and the subsequent ulnar collateral ligament elbow injury that lead to "Tommy John" reconstruction of that ligament last summer. Dr. Morgan said that he had predicted elbow problems in Strasburg by watching the way he held his shoulder.

More on how the arm bone is connected to the...after the jump.

  • Thanks PHIL.

    Boy, that is a nifty K:BB ratio Hudson has going at almost 4:1!

    I hope he continues improving.

  • And of course the Bucs won again playing AZ (not PHIL). They dont seem to have a problem yet with the bottom feeders.

    They picked up 3 games this last week.

    I'm looking forward to them coming to the Chi.

  • Don't mess with the SI jinx. Since the Javy/Cubs cover came out, he is 2-for-20 with no walks.

  • BRADSBEARD: If all three are assigned to Eugene, the Cubs can play Galindo, Paredes, and Paniagua at the same time by moving Paredes between SS-3B-DH, Galindo between 3B-1B-DH, and Paniagua between 1B-LF-DH. 

    The Cubs like to have their players (including their minor leaguers) learn to play more than one position even if they eventually are projected to settle at one spot, and I suspect that will be reflected at Eugene, with just about everybody who will be assigned there able to play at least two positions.

  • Thanks - at least the scorer was consistent

  • I don't think the error call was completely out of the blue but the ball took a very bad hop and would have taken a very good play to get it. Same with one of the Stella throws where I think it could have easily been ruled a hit. Neither were cut and dry calls though imo.

  • chased a high fastball...

    I think his BABIP during his run has been around .950

  • Great stuff CubbyBlue!!! I think it inspired today's six spot as well.

  • That's all fine and good, but I think it's short-changing the Arrieta-like affect of his beard

  • Was the error scored on Zobrist's third ab ruled correctly? Ron was saying that it was a pretty tough chance for the fielder

  • Did anybody see that Zobrist strikeout?

    That was extremely disappointing.

  • Strangest win of the year, and one of the sweetest. Twice I thought it was easily in the bag, then after the first 2 hitters in the 9th I thought all was lost. Big game for Grimm, Strop & Rondon. But, man, those Cards can hit for power.

  • Very satisfying, gut-check win today. The beers on the trip back to Chicago are going to taste fantastic.

  • It's still very early but this game felt very important to me and probably knocked 2 years off my life. Seemed like every inning was big.

  • This is the exact game that the Cubs would have lost in years past to the Cardinals.
