What does the Lateral Scapular Slide Test assess?

• A. The strength of rotator cuff muscles
• B. Scapular position at various degrees of arm abduction
• C. The presence of pain during shoulder flexion
• D. Stability of the humeral head

Answer: (B)

The Lateral Scapular Slide Test is designed to assess scapular position and dyskinesis during arm movement, particularly at various degrees of arm abduction. This test evaluates the relationship between the scapula and the humerus and how the scapula stabilizes and moves with the arm. By assessing the position of the scapula in different degrees of abduction, clinicians can determine if there are any abnormalities, such as winging or tipping, that may contribute to shoulder dysfunction or pain.

This assessment is particularly useful for identifying scapular dyskinesis, which can indicate problems with the muscles responsible for scapular control, but it focuses specifically on the position and movement of the scapula rather than directly measuring strength, pain, or joint stability. Hence, the essence of the test aligns correctly with the option regarding scapular position during arm abduction.
