What movement does the deltoid control?
Deltoid muscle functions include: Arm abduction, which means raising your arm out to the side of your body. Compensation for lost arm strength if you have an injury, such as a rotator cuff tear. Flexion (moving your arm forward, toward an overhead position) and extension (moving your arm backward, behind your body).
