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.

  • Reds pitching meeting tomorrow:

    "Hey coach...maybe we should walk Bryant?"
    "No...keep challenging him with fastballs! What kind of man are you?! The Cubs walked Harper, and look what happened there! They got teased for it, by one of the Nat players! Is that what you want?"

  • Ian Happ is hitting.733 after 5 games at Tennessee. He went into tonight's game hitting .667 -- and went 3-for-3 to raise his average.

    2-for-3, including a bomb, for LaStella at Iowa. Pierce Johnson very bad -- 2IP, 5ER. Pitching prospects not looking so hot -- Underwood has been awful.

    Did Jiminez get hurt? I noticed he came out early yesterday.

  • Contreras keeps hitting/walking like this, and Miggy keep up the poor D and lack of offense - the kid could be the #1 catcher very soon.

  • it doesn't hurt that the Cardinals lose the KC and the Pirates lost too.

  • ...still trying to process what I just saw. From both KB and Jake. Walking Billy Hamilton twice is a cry for help. I think the nudie photos are messing with Jake's head.

  • damn...totally missed that ruben quevedo died on june 7th. he was only 37...heart attack.

    he threw some really horrible games for the cubs in 2000 and followed it up by doing the same for 3 season for the brewers.

  • Hitting 3 HR, 2 doubles in a game. Never been done in mlb history per Len/Bob.

  • walks? this is baseball, not a nature hike. he needs to get his head in the game.

    in my opinion, he would have been better off hitting 2 homers rather than walking twice. /moneyballs
