Want to read a great article that discusses types of scapular patterns? Check out “The Disabled Throwing Shoulder: Spectrum of Pathology Part III: The SICK Scapula, Scapular Dyskinesis, the Kinetic Chain, and Rehabilitation” by Burkhart S, Morgan C, and Kibler B. The authors discussion of scapular mal-position and it’s relationship to pain patterns is very similar to the content presented in Impingement and Instability. Although the treatment approach is different from PRI, the muscles identified as being weak are main muscles of the BC chain. To get a copy of this article, contact us!
