The rotator cuff is a group of muscles and tendons that attach to the bones of the shoulder joint, allowing the shoulder to move and keeping it stable.
The tendons of the rotator cuff pass underneath a bony area on their way to attaching the top of the arm bone. These tendons join together to form a cuff that surrounds the shoulder joint. This provides the stability of the joint and allows movement of the arm bone on the shoulder bone.
Injury to these tendons may result in:
Rotator cuff tendinitis, when irritation and swelling of these tendons is present
A rotator cuff tear, when one of the tendons is torn due to overuse or injury

These injuries often lead to pain, weakness, and stiffness when you use your shoulder. A key part in your recovery is starting exercises to make the muscles and tendons in your joint stronger and more flexible.
Your doctor may refer you to a physical therapist to treat your rotator cuff. A physical therapist is trained to help improve your ability to do the activities you want.
Muscle Strengthening and Stretching
Many muscles surround your shoulder and lower back. When all of these muscles are working together well, they serve to stabilize your shoulder joint. When your shoulder is stabilized, there is less strain on your shoulder joint and muscles when you are active.
Before treating you, a doctor or therapist will evaluate your body mechanics. The therapist may:
Watch how your shoulder moves as you perform activities, including your shoulder joint and your shoulder blade
Observe your spine and posture as you stand or sit
Check the range of motion of your shoulder joint and spine.
Test different muscles for weakness or stiffness
Check to see which movements seem to cause or worsen your pain
After testing and examining you, your physical therapist or doctor will know which muscles are too weak or too tight. You will then start a program to stretch out your muscles and make them stronger.
The goal is to teach you proper techniques for using your shoulder with everyday activities, at work, or during sports. Exercises can help you heal from an injury and avoid re-injury.
The goal is for you to function as well as possible with little or no pain. To do this, your physical therapist will treat your shoulder pain, help you strengthen and stretch the muscles around your shoulder, and teach you proper techniques to move your shoulder, for either everyday tasks or sports activities.
Before doing exercises, have your doctor or physical therapist make sure you are doing them properly. If you have pain during or after an exercise, you may need to change the way you are doing the exercise.
Most exercises for your shoulder work to either strengthen (make stronger) or stretch the muscles and tendons of your shoulder joint.
