1. Strength Testing of the Rotator Cuff Muscle
Strength testing of the rotator cuff is assessed using resisted motion. The following resisted motions should be tested:
2. Special Tests for Subacromial Pain Syndrome (SAPS)
The signs are used to diagnose subacromial pain syndrome (SAPS). Three signs are elicited by passively moving the shoulder into the following positions while watching for pain or lack of motion.
3. Instability Tests
Several tests can be done to assess for glenohumeral joint instability. These include:
4. Labrum Tests

The shoulder exam continues by checking the strength of the rotator cuff muscles and biceps tendons. The rotator cuff muscles (supraspinatus, infraspinatus, teres minor, and subscapularis) act as compressors, holding the humeral head in place against the glenoid. Injury and degeneration of the rotator cuff tendons are the most common sources of shoulder pain.
The strength testing of the rotator muscle is performed by testing motions against resistance applied by the examiner. Pain with these resisted motions suggests tendonitis; weakness suggests a rotator cuff tear. The strength test is followed by tests for subacromial pain syndrome (SAPS), shoulder instability, and labrum injury. It is important to test both shoulders and compare the sides. The opposite shoulder should be used as the standard to evaluate the injured shoulder, provided it has not been injured as well.

The clinical evaluation of the shoulder begins with inspection, palpation, and testing range of motion, followed by strength testing of the rotator cuff and biceps muscles. While assessing the strength of the rotator cuff muscles, it is essential to differentiate true muscle weakness from a painful inhibition of strength that can be seen with severe tendonitis. The next part of the exam is the assessment for signs of subacromial pain syndrome (SAPS), using Neer's, Hawkins, and crossover tests. Pain or lack of motion ...
