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.

  • Oh my! Cards down 2-1 to Reds in the bottom of the 9th -- get a leadoff triple -- and don't score!

  • Gameday has stopped at the top of the 8th inning. Google tells me it ended up 8-4 Pirates but I can't get further detail. Guess I'll have to wait until the Cubs' website updates...

  • Dear Baseball Gods--
    My trip to Chicago has nothing whatsoever to do with the Cubs. In actuality, I am a Red Sox fan.
    Sincerely,

  • Strange, because he really seemed to have the Pirates number last year.

    Bummer for Jake -- I think this is the first time all year his ERA has been over 3.00, and that will be his number for the year.

  • 3rd time this season he's given up 6+ runs to PIT...only team he's given up 6+ runs to this season.

    7 runs is the most he's given up since august 6th in colorado...in 2014.

  • coghlan out...got his cleats stuck in the wall attempting a play (failed, but looked great doing it). walking off on his own, precautionary/day-to-day looking stuff...hopefully not worse.

    also, jake arrieta is literally worse than hitler. 1-5, bottom 5. ...make that 1-6, bottom 5. ...make that 1-7, bottom 5.

  • Coghlan crashes into wall and comes up limping, looks like left knee or ankle. Leaves game...

    Arrieta inspiring no confidence yet again.

    When he left Boston after nine years as general manager, Epstein said he believed in the philosophy espoused by legendary football coach Bill Walsh: essentially that 10 years is a natural shelf life for a high-stress job.
