What causes poor shoulder internal rotation?
A decrease in IR can often be attributed to overactive or shortened infraspinatus or teres minor muscles, and joint dysfunction due to capsular contraction of the posterior shoulder ligaments. This loss of mobility is so common that the term glenohumeral internal rotation deficit (GIRD) is used to describe it.
What is internal arm rotation?

What causes poor shoulder mobility?
Mobility issues that develop in the shoulder can result from several types of activity or inactivity. Some of the most common types of shoulder mobility issues are impingement, rotator cuff tears, and frozen shoulder. Instability and overuse of the joint cause many of these.
