Throwing athletes face unique shoulder challenges that standard medical approaches often fail to address. This deep dive into shoulder pain reveals why the timing and location of pain matters more than most practitioners realize. When throwers experience pain at layback position—that critical moment when the arm is fully rotated backward before acceleration—it requires far more than rest and ice to properly heal.
The biomechanics at play are fascinating. The biceps tendon and anterior capsule frequently become irritated from excessive forward translation of the humeral head, primarily caused by insufficient external rotation range. This limitation forces compensatory movements that stress structures not designed for such demands. While 80% of overhead athletes show some labrum involvement on imaging, most remain pain-free—highlighting the disconnect between structural findings and actual function.
Most surprising to many athletes is that GIRD (Glenohumeral Internal Rotation Deficit) isn't something that needs "fixing." This adaptive change represents a normal, even beneficial evolution for throwers, combining bony adaptations with soft tissue changes that enable high-velocity movements. Working to increase internal rotation through techniques like sleeper stretches can actually be counterproductive.
The treatment approach outlined reveals how limited shoulder mobility creates a cascade of compensatory patterns—from the characteristic "W position" at layback to increased medial elbow stress (potentially leading to Tommy John surgery) and even lumbar spine issues. Effective intervention requires understanding these interconnections and addressing the entire kinetic chain: improving subscapularis function, enhancing pure external rotation, optimizing thoracic mobility, and establishing proper scapular control.
