Rotator cuff impingement is what happens when the tendons and bursa in the sub-acromial/suprahumeral area are compacted together. Compression can initiate painful friction, stress and mechanical wear on the shoulder. Classic signs and symptoms include pain when flexing or abducting the shoulder above 80 degrees and weakness in the shoulder muscles, which are often detected when the patient is given the Hawkins-Kennedy and Neer impingement tests. This impingement disorder mostly stems from athletes and individuals whose jobs require constant overhead lifting, but can also be the result of an unstable glenohumeral joint caused by aging or tendon pathologies. Because there are multiple causes of rotator cuff impingement, it is classified into two categories; primary and secondary. Furthermore, rotator cuff impingement is categorized into three different stages related to age and the deterioration of the rotator cuff.

A good example of this is when an individual has a curved (type II) or hooked (type III) acromion that decreases the size of the sub-acromial space. Secondary impingement refers to hypermobility in the joint caused by translation of the humeral head.
Stage I: Usually takes place in patients 25 and younger, with noted hemorrhage and edema. The pain is generally worsened when the shoulder is abducted more than 90 degrees.
Stage II: Affects middle age patients (25 to 40 years old), with documented tendonitis and fibrosis. This stage is said to be irreversible because of the repeated stress over a long period of time. Pain is prevalent in daily routine and while resting at night.
Stage III: Typically happens in patients over 40 years old, with cases of bone spurs and ruptured tendons. The main cause is recurring shoulder pain and muscle
