What is the Infraspinatus Muscle?

The infraspinatus muscle is on the back of the shoulder blade and connects to the top of the upper arm. It helps rotate the arm outward and supports shoulder joint stability. Though it works in silence, injury or strain to this muscle can lead to sharp or lingering pain.

• It forms part of the rotator cuff group and aids smooth shoulder rotation.

• It holds the arm bone securely within the shoulder socket during motion.

• It works constantly during pulling, lifting, and overhead reaching movements.

• It shares load with other rotator cuff muscles, balancing shoulder effort.

• It stretches whenever you reach behind your back or head.

• It lies under the trapezius muscle, close to bones and other soft tissues.

• It plays a role in preventing dislocations during fast or forceful arm actions.
