The two most popular tests for shoulder impingement are the Neer test and the Hawkins test. In the Neer test (below left), the examiner stabilizes the scapula while passively elevating the shoulder, in effect jamming the humeral head into the acromion. In the Hawkins test (below right) the examiner elevates the arm to 90 degrees of abduction and forces the shoulder into internal rotation, grinding the cuff under the subacromial arch.
A nucleic acid test, often called a NAT, (or nucleic acid amplification test - NAAT) is a molecular technique used to detect a virus or a bacterium. These tests were developed to shorten the window period, a time between when a patient has been infected and when they show up as positive by antibody tests.
