Scapular Abduction Syndrome

Scapular Abduction Syndrome

Medical Diagnoses:

  • Glenohumeral joint impingement
  • humeral subluxation (anteriorly)
  • tendinopathy – biceps, infraspinatus, and supraspinatus
  • bursitis – infradeltoid
  • interscapular pain in teh rhomboid and middle trapezius
  • sternoclavicular joint pain


Pain in the shoulders or upper back related to the scapula sitting too far away from the spine (>3 inches).   This positioning is evident at rest and gets worse with active elevation of the arm.  Increased muscle length of the trapezius and rhomboids and decreased muscle length of the serratus anterior cause this problem.

Diagnostic Tests:

  • Lengthened trapezius and rhomboids
  • Shortened deltoid or supraspinatus.
  • Hypertrophied scapulohumeral muscles and possibly pec major.
  • Short pectoralis major.
  • Decreased pain with corrected scapular posture.


  • Improve the muscle length and mobility of the pecs:

Self Release for the Pecs – Ben Bruno.  I like these stretches except for number 2.  I feel that number 2 can be performed correctly, but it also can be performed incorrectly adding stress to the anterior joint capsule of the shoulder.  So if you know how to do it, then go ahead, otherwise skip it. ,

  • Improve muscle length and mobility of the serratus anterior, deltoid, and supraspinatus.
  • Decrease the length and improve the strength of the trapezius and rhomboids.
  • Taping for postural support.
