Impingement usually occurs from repetitive and chronic compression of the rotator cuff tendons in the subacromial space. These tendons help hold your arm in place, provide shoulder stability and enable movement.

What is the impingement position?

The shoulder impingement zone is the most likely area when injuries to your rotator cuff or shoulder bursa occur due to the narrowing of the sub-acromial (space below the acromion) during this shoulder position.

What is an impingement in the shoulder?

Impingement syndrome describes a condition in which the tendons of the rotator cuff of the shoulder are pinched as they pass between the top of the upper arm (humerus) and the tip of the shoulder (acromion). The rotator cuff is a group of four muscles and bones that share a common tendon.
