Impingement Syndrome - Neer Test

Impingement syndromes are a spectrum of conditions caused by a narrowing of the subacromial and subcoracoid spaces, leading to impingement of the rotator cuff tendons and/or the subacromial bursa between the humeral head and the acromion. Impingement syndromes typically manifest as shoulder pain that is exacerbated on raising the arm overhead. The Neer test is used to clinically identify a potential subacromial impingement syndrome. This test is performed with the patient in a seated posture. The examiner stands on the same side as the shoulder being examined. With one hand stabilizing the ipsilateral scapula, the examiner internally rotates the patient's arm and then raises the arm overhead, thus narrowing the space between the greater tubercle and the coracoacromial arch. Elicitation of pain on performing this maneuver is considered a positive Neer test for subacromial impingement syndrome.
