Do this by asking the patient to identify and 'scratch' on the opposite scapula, both sides from above and below. Pain, restriction or asymmetry in these movements may be considered "positive".

Shoulder pain is common among patients. The unique anatomy and range of motion of the shoulder joint can present a diagnostic challenge, but proper clinical evaluation often reveals the cause of the pain.

The most common cause is that many forms of the wrong shoulder joint will cause pain during this back-scratching test.

The test is performed to evaluate the range of action of the shoulder joint, specifically, the range of movement of the arm, and the range of activity in or out of the shoulder joint. Although it suggests shoulder ligament, muscle damage to the shoulder, most of the sheath, ligament, muscle or bone damage in the shoulder joint has a positive result.

The Apley's back scraping test is a good test to evaluate overall shoulder joint function. However, there is no specific functional evaluation of the anatomical aspect of the shoulder joint, but the assessment of the range of activity of the shoulder joint is more.
