What is Impingement syndrome?

Put simply, it is the irritation of rotator cuff tendon under the acromion (a bony roof that covers the tendon).

There are a variety of causes ranging from abnormal shape of the acromion (curved or hooked) to dysfunction of the rotator cuff tendon that can lead to imbalance of the shoulder girdle and functional impingement as the cuff can no longer effectively compress the ball of the joint during overhead movements. This leads to dynamic impingement of the tendon. Sometime repetitive overuse as in athletes involved in throwing sports (javelin, fast bowling etc).

  • Dull, sometimes nonspecific aching pain around shoulder
  • Worse pain during overhead movements
  • Difficulty in lying on the affected side, sleep may be disturbed.
