As sports fans and athletes alike know, shoulder injuries are serious business. They can be extremely painful, limiting, and slow to heal. As physical therapist and founder of WebPT Heidi Jannenga explains, the rotator cuff is a common shoulder injury site, though there are plenty of exercises to help you recover.

What Is a Rotator Cuff Injury?

The rotator cuff is a group of four muscles that stabilize the shoulder and allow it to move. Jannenga says you should visualize the head of the arm bone as a golf ball, and the area of the shoulder blade as a golf tee. “The rotator cuff serves as a sleeve that enables the ball to spin and roll while remaining on the tee,” she says.

The most common rotator cuff injuries are impingements and tears. An impingement occurs when a rotator cuff muscle swells and cramps the space between the arm and shoulder bones, causing pinching. Muscle strain or other overuse injuries, as well as bone spurs, are common causes of swelling.  

A less common injury, a rotator cuff tear occurs when a rotator cuff tendon or muscle is torn. “There are many degrees of a tear, most of which do not require surgery,” Jannenga says. “The depth, or thickness, of the tear, as well as the muscles affected, determine the degree of the tear.”

Repetitive, overhead motions can wear down the rotator cuff muscles and are thus a common cause of injury. This is why athletes such as baseball pitchers frequently have shoulder issues. A traumatic injury, such as falling onto your arm, can also cause injury. Regardless of how it happens, the risk of a rotator cuff tear increases as we age and the wear on our bodies accumulates.

What to do After an Injury?

Jannenga suggests using the “RICE” method immediately following an injury; rest, ice, compression, and elevation work together to reduce pain and swelling. Once swelling has gone down and moving your arm is no longer painful, exercises such as the following can help you heal and prevent issues such as “frozen shoulder” or range of motion loss.

Heidi recommends using a light dumbbell or resistance band for many repetitions. If you do not have a light dumbbell, try using a can of soup.

Doorway Stretch

  1. Warm up your muscles by standing in an open doorway and spreading your arms out to the side.
  2. Grip the sides of the doorway with each hand at or below shoulder height, and lean forward through the doorway until you feel a light stretch.
  3. Keep a straight back as you lean and shift your weight onto your toes. You should feel a stretch in the front of your shoulder. Do not overstretch.

Side-Lying External Rotation

  1. Lie down on the side opposite your injured arm.
  2. Bend the elbow of your injured arm to 90 degrees and rest the elbow on your side. Your forearm should rest across your abdomen.
  3. Hold a light dumbbell and, keeping your elbow against your side, slowly raise the dumbbell toward the ceiling. Stop rotating your arm if you feel strain.
  4. Hold the dumbbell up for a few seconds before returning to the start position with your arm down.
  5. Repeat three sets of 10 up to three times a day. Increase reps to 20 when 10 becomes easy.

High-to-Low Rows

  1. Attach a resistance band to something sturdy at or above shoulder height. Be sure it is securely held so it doesn’t come lose when you pull on it.
  2. Get down on one knee so the knee opposite your injured arm is raised. Your body and lowered knee should be aligned. Rest your other hand on your raised knee.
  3. Holding the band securely with your arm outstretched, pull your elbow toward your body. Keep your back straight and squeeze your shoulder blades together and down as you pull. Your body should not move or twist with your arm.
  4. Return to start and repeat three sets of 10.

Reverse Fly

  1. Stand with your feet shoulder-width apart and your knees slightly bent. Keep your back straight and bend forward slightly at the waist.
  2. With a light weight in each hand, extend your arms and raise them away from your body (do not lock your elbow). Squeeze your shoulder blades together as you do so. Do not raise your arms above shoulder height.
  3. Return to start and repeat three sets of 10.  

Lawn Mower Pull

  1. Stand with your feet shoulder-width apart. Place one end of a resistance band under the foot opposite your injured arm. Hold the other end with the injured arm, so the band goes diagonally across your body.
  2. Keeping your other hand on your hip, bend slightly at the waist (do not lock your knees) so the hand holding the band is parallel to the opposite knee.
  3. As if starting a lawn mower in slow motion, straighten upright while pulling your elbow across the body to your outside ribs. Keep your shoulders relaxed and squeeze your shoulder blades together as you stand.
  4. Repeat three sets of 10.

While these exercises can help build strength after a minor injury, a major or recurring injury requires more attention. Consult a doctor if you experience pain (or a deep ache), swelling, difficulty raising your arm, or difficulty sleeping on your arm more than a few days after your injury.
