In a wall angle progression, which component should be considered second after establishing neutral spine alignment?

• A. Clavicle alignment
• B. Scapula
• C. Humeral head position
• D. Foot placement

Answer: (B)

Focusing on the scapula next is essential because it provides the stable base for shoulder movement once the spine is neutral. When the scapula is set in a slightly depressed and retracted position against the rib cage, the shoulder girdle becomes a solid platform for the arm to move, promoting proper glenohumeral joint tracking and reducing compensations like elevation or protraction. This scapular positioning guides subsequent adjustments to the humeral head, ensuring the arm moves within a safer, more coordinated path. Foot placement and clavicle positioning are less central at this stage, while the scapula sets the foundation for the rest of the movement.
