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.

  • When we played the Reds with Chapman, I always thought of it as an eight-inning game. So now other teams have eight innings to try to get a lead against the Cubs. Should be a challenge, assuming three or four Cubs ever start hitting again.

    I don't really try to get to know and like these players personally. I'm rooting for laundry, for the most part. Exceptions might be when a player makes trouble in the clubhouse or in the dugout. (Zambrano and Bradley come to mind. Also Papelbon.) But I don't think Chapman is one of those jerks.

  • Unfortunately, a pretty good summary. It looks like next year Heyward will be getting yet another batting stance adjustment.

    The recent good news has been Baez. I'm afraid about the next league adjustment on him, though, which is probably right around the corner.

    Bryant I don't worry about too much. Just not seeing the ball well right now. He'll turn it around. Russell's been good with men in scoring position all year and he's 22ish. He'll be fine but next year is likely to be his breakout year.

  • If Travis' back-to-back-to-back walks cost Hendricks the ERA title, that would really suck.

  • This place is a real downer after a loss to the Sox.

  • I expect they will go 5-9 games above .500 the rest of the year. 96-98 wins will win the Division.

    They should have one more 2-3 week hot streak in them.

    However, several players are just "average" for the last month: Zobrist, Ross, Russell, Ceasar. Montero is terrible, plus he cannot throw anyone out. -WAR. Heyward is abysmal at the plate, but a plus in the OF. Still with RISP he has been terrible. KB has not been driving in runs as of late. But Apparently the team is still above average with RISP according to S Sahadev.

  • I came to that realization tonight. I kept expecting them to play better, but now I realize they aren't going to. They are a .500 team now.
    - They have one reliable starting pitcher. Jake's magic is gone, and it doesn't look like it's coming back. Lester has been lousy recently. Lackey's ERA goes up every time he pitches.
    - Heyward has been dead weight all year. I can't remember a single series where he was a significant offensive contributor. Not one. Great defense, but but if he were hitting .270 with 10 HR and played average defense, the Cubs would be better off.

  • Team is .500 since early May and is playing like a .500 team. Lack of offense seems to be putting a lot of pressure on the pitchers...and they aren't handling it terribly well.

    .500 the rest of the way still may win the division though.

  • ...i hate espn.

    nothing like settling into a cubs game to get a few minutes cutaway for an ortiz AB in the 6th inning of the det/bos game.

    oh, at least they're doing split screen now...i guess.

  • The next 2 games are nationally televised. I think we dominate tonight, hitting 3 HRs off Shields. Great night for KB to end HR drought facing HR prone pitcher in one of the most hitter friendly parks in the league.

  • If the ball didn't deflect off the pitcher's mound, the game wouldn't have ended. Montgomery did miss his location though, but if that same contact was made and went in any of direction, good chance of ground out if it doesn't get through.

    If it was 1 night later, Chapman would be out there and we probably would be going to extras.

    Also, If KB wasn't robbed of a HR, perhaps we would have won. We will never know. Nice play by Melky though.

  • The comparison isn't Chapman replacing Rondon. It's Chapman replacing Richard (hopefully) in the pen. Chapman's better.
