Which test checks the joint between the clavicle and scapula during downward movement of the clavicle?

The acromioclavicular test is specifically designed to assess the integrity and functionality of the acromioclavicular joint, which is the joint between the clavicle and the scapula. During this test, the clinician observes how the joint behaves under stress, especially when the clavicle is subjected to downward movement. An improper or abnormal response during this movement can indicate issues such as acromioclavicular joint injury, instability, or other related pathologies.

This test is vital in the context of sports medicine as it helps determine whether the joint is functioning correctly, particularly for athletes who place significant stress on their shoulder joints. Understanding the mechanics of the acromioclavicular joint is crucial for diagnosing and managing shoulder injuries effectively.
