Shoulder impingement syndrome. Shoulder impingement syndrome is a syndrome involving tendonitis (inflammation of tendons) of the rotator cuff muscles as they pass through the subacromial space, the passage beneath the acromion. It is particularly associated with tendonitis of the supraspinatus muscle. [1] This can result in pain, weakness, and ...
The Hawkins-Kennedy test [11] [12] has a sensitivity of approximately 80% to 90% for detecting impingement. The infraspinatus and supraspinatus [13] tests have a specificity of 80% to 90%. [10] A common cause of shoulder pain in rotator cuff impingement syndrome is tendinosis, which is an age-related and most often self-limiting condition. [14]
Subacromial bursitis. Subacromial bursitis is a condition caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon (one of the four tendons of the rotator cuff) from the overlying coraco-acromial ligament, acromion, and coracoid (the acromial arch) and from the deep surface of the deltoid muscle. [1]
They call it impingement syndrome because your rotator cuff tendons literally get “impinged” between the round head of your shoulder joint and a hook-shaped bone in the front of your shoulder ...
Tip: Avoid lifting your elbows above shoulder height if you're concerned about impingement or feel any discomfort using a larger range of motion. If you already have shoulder impingement and feel ...
Primary shoulder problems may cause pain over the deltoid muscle intensified by abduction against resistance – the impingement sign. This signifies pain arising from the rotator cuff, but cannot distinguish among inflammation, strain, or tear.
