Shoulder impingement syndrome

SIS is sometimes called swimmer’s or thrower’s shoulder, as it is most often caused by overhead arm movements, such as in swimming or racket sports. It is a result of the tendons of the rotator cuff becoming irritated and inflamed as they pass through the shoulder joint, leading to pain, reduced movement and weakness in the shoulder. If left untreated, a rotator cuff tear can occur.

Stretching is very important in preventing or repairing SIS, as well as ensuring that any movements that involve lifting the arm out to the side (abduction) above horizontal are done with the arm rotated outwards. The same applies to movements lifting the arm up forwards (flexion).

Additionally, exercises that strengthen the rotator cuff should be done regularly, as well as attempting to maintain good posture.
