Is Your Shoulder Pain a Sign of Subacromial Impingement Syndrome?
Published: Jan 17, 2024
Subacromial impingement syndrome (SIS) is a common cause of shoulder pain, often affecting those who engage in repetitive overhead activities. Understanding its causes and symptoms can help in managing the discomfort and improving functionality.

What Causes SIS?
SIS occurs when shoulder structures like the rotator cuff and bursa are compressed. Activities that involve repetitive shoulder movements, such as painting or playing sports like tennis, increase the risk. Age is another factor, with older adults being more susceptible.
Understanding the Anatomy
The shoulder is a complex joint allowing a wide range of motion. However, this flexibility can lead to compression of tissues, causing pain. The acromion, a part of the shoulder blade, can vary in shape and contribute to susceptibility to SIS.

Symptoms to Watch For
Typical symptoms include pain during overhead activities and discomfort at night. Athletes might experience stiffness or prolonged warmup periods. A careful physical examination can help identify SIS, though no single test is definitive.
