Shoulder impingement is an overuse injury that
causes achy pain on the front or side of the shoulder. The pain is felt most
when the arm is overhead or extended to the side. Shoulder impingement also is
called rotator cuff tendonitis, subacromial impingement, supraspinatus
tendonitis, and shoulder bursitis.
Shoulder impingement is common in swimmers and
athletes who play baseball, tennis, and volleyball. It can also occur in weight
lifters, gymnasts, divers, and rowers. Causes include a rapid increase in
overhead activity, weakness or strength imbalance in the rotator cuff or
scapular muscles, postural abnormalities, shoulder joint instability, or
improper training or technique.
The following is information from the American
Academy of Pediatrics summarizing treatment phases and goals for shoulder
Treating shoulder impingement involves limiting
activities that cause pain and using ice and nonsteroidal anti-inflammatory
drugs (NSAIDs) to help reduce inflammation. The symptoms of shoulder impingement
will subside with rest, but the condition will not fully resolve until the
underlying causes have been identified and corrected.
1. Limit overhead activity
or anything that causes pain.
Pitchers—Limit pitching; may try playing
first or second base.
Tennis—Limit serves and overhead shots.
Swimmers—Limit butterfly, freestyle, and hand
2. Ice, NSAIDs.
1. The other phases of
rehabilitation will not be effective until pain is
2. Swelling inside the
shoulder may worsen the pain and contribute to further
3. Pain may be reduced by
limiting activities or changing technique for painful
1. Correct poor posture.
2. Restore strength to
1. Stretch anterior chest
wall muscles; strengthen inter-scapular muscles with
rowing-type exercises (Figure 1), and strengthen scapular
stabilizers with shoulder protraction exercises (Figure
2. Use elastic tubing or
weights to strengthen external rotators of shoulder.
1. Continue with aspects of
the sport that don't require overhead motion or cause
2. General conditioning,
including aerobic exercise (running, cycling, kicking drills
3. Lower extremity and trunk
1. Resume overhead motion
gradually as symptoms permit.
2. Correct technique or
1. For pitchers, follow a
graded return-to-throwing program.
2. Consider biomechanical
assessment if technique errors are suspected in a pitcher,
swimmer, or tennis player.
