What direction of movement occurs during elevation/depression of the sternoclavicular joint?

During elevation and depression of the sternoclavicular joint, movement occurs in opposite directions. When the shoulder girdle elevates, which typically involves the scapula moving upward, the clavicle moves in a downward direction at the sternoclavicular joint. Conversely, during depression of the shoulder girdle, the scapula moves downward while the clavicle simultaneously moves upward at the joint. This relationship is crucial for shoulder motion and allows for the coordinated function of the upper extremity. Understanding this movement pattern is key for assessing shoulder dysfunction or designing rehabilitation programs following injuries or surgeries to the shoulder region.
