In assessing wall angle performance, which anatomy is prioritized for stability before raising the arms?

• A. Scapula
• B. Elbow
• C. Wrist
• D. Ankles

Answer: (A)

Stability of the shoulder girdle, specifically the scapula, is prioritized because it sets the foundation for the entire overhead movement. The scapula sits on the thorax and provides the base for the humerus to move with proper alignment; when it is stable, the glenohumeral joint can elevate without compensations such as winging or excessive tipping. In wall angle tasks, you cue scapular setting—subtle retraction and upward rotation—to keep the scapula in a stable position while the arms rise. The elbow, wrist, and ankles are distal and play little role in establishing that initial stability, so without a solid scapular base, arm elevation mechanics become unstable and less efficient.
