In the assessment of postural alignment, how can you identify protraction of the scapula?

Identifying scapular protraction involves an assessment of the position of the acromion relative to the plumb line. When the acromion is positioned in front of the plumb line, it indicates that the scapulae are protracted. This aligns with the definition of protraction, where the shoulder blades move away from the spine and towards the front of the body, leading to a more forward position of the acromion.

In a balanced and aligned posture, the acromion would typically fall in line with the plumb line. If it is positioned behind the plumb line, it may indicate retraction or a more neutral scapular position. A higher position of the acromion relative to the plumb line may suggest elevation rather than protraction. Thus, the clear identification of protraction as signified by the acromion being in front of the plumb line is essential for proper postural analysis.
