Infraspinatus The origin of the infraspinatus is the fossa of scapula. It inserts into the back of the shoulder joint capsule (posterior aspect of greater tuberosity of humerus). Action The infraspinatus muscle laterally rotates the arm. It is the primary muscle force resposible for external rotation. It also adducts the arm and is involved in extension at the shoulder joint. Test Slightly abduct the arms and bend the elbows bent at 90 degrees. Place your hands on the outside of their arms. Encourage gentle force that opens their arms and externally rotates them. |
