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.

  • I thought the same. It'd be great luck to face these non-contenders after the trade deadline.

  • At the start of the season the book was that he was trying to pitch to more contact so he could stay in the game longer and it seems to be working so far. Contact against is 77.5% this year and it was 70.2% the year before. He averaged 6.7 IP/game last year and so far it's 7 IP/game. His actual pitches per game are only down to 106.1/game from 107.2/game last year but if he's able to go a bit farther into games without throwing more pitches and without giving up more runs that is a good thing.

  • sale's skills and insane value makes it almost too hard to have a market for the guy...he's got 3/38m owed to him over 3 seasons (2 team options). he could easily pull in 30m/yr if he was on the market as a FA.

    he's throwing a bit differently this season, especially with more sliders and less changeups like earlier in his career, but all his stuff still looks great even if the HRs are a little elevated and the Ks are down.

  • Torres, Happ, McKinney, Jimenez, and Candelario for Sale. Deal or no deal?

    "The White Sox are reportedly asking for “five top prospects” for Chris Sale, FanRag Sports’ Jon Heyman reports."

  • Unless he develops 30+ HR power and keeps his walk rate close to his K rate at the MLB level, he's not going to turn into Prince Fielder. And even if he does turn into Prince Fielder, he's gonna have a short prime. His very limited athleticism is likely to also detract some value from his ability to reach base--I don't buy making an out as being preferable to base clogging, but you'd certainly prefer just about any base runner other than Vogelbach, David Ortiz, etc.

  • seeing as arod has played a total of 27.1 innings of D at 1st/3rd and somehow managed a -0.5 dWAR with his 1 error at 1st and an overall positive total zone rating...he might end up even more in the shitter via the characteristics/flaws/whatever of how some sites determine various WAR values. dWAR doesn't directly lead to a WAR value, but the 2 main entities pushing the most popular variations of WAR sometimes lead to some interesting discrepancies in value.

  • I have a lot of faith in Baez that he's going to turn into a more consistent, solid player. It looks like it took him about a half season or so of futility at the plate to figure out he was not talented enough to get away with the crazy approach he had. I think his running game will eventually have a more measured aggression.
