GIRD

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.

  • Brian Matusz, supposedly he has attachments. Hope it's not like an email with a virus attached.

  • One thing to remember about Chapman -- he can be magic, but his ERA is higher than Rondon's this year. 100+ mph is fun, but I'd love to see a few more sliders. I think he enjoys the crowd reaction from 103 mph.

  • Wow -- Chapman gives up a hit and everything completely caves in. I think the Cubs went into collective shock.

    Stolen base with the pitcher holding the ball, WP that should have been caught or blocked, then Russell with a 2-out error on a routine play. Cubs handed them 2 runs. Throw in a Fowler bobble and it was a mess.

    Hopefully, that is all out of their system now -- let's get a W tomorrow.

  • First time I've ever seen a base running slump -- he's made some poor decisions recently, but I thought it was a great idea to try to score there -- it's not like Heyward was going to get a 2-out hit against a LHP. Sliding feet-first into home is probably the safe (ugh) way to go, but it's hard to get the foot on the plate.

  • Yup. He got squeezed (twice) on the first walk, but, when you have one-run lead and the other team is trying to make an out -- take the out.

  • Clearly the Cubs need to clear out the farm and trade for another closer

    Where's Ed Lynch when you need him?
