Initial evaluation of chronic, overhead throwing-related shoulder injuries^*

AP: anteroposterior; GIRD: glenohumeral internal rotation deficit; SICK: scapular malposition, inferior medial border prominence, coracoid pain and malposition, and dyskinesis of scapular movement.

* Chronic injuries typically entail a vague or longer period (eg, months) during which symptoms developed; acute injuries often involve a specific incident when symptoms were first noted.
