During scapular elevation testing in anti-gravity, what is the test position?

During scapular elevation testing in anti-gravity, what is the test position?

• A. Seated with arms by the sides; stabilization achieved through subject compliance; resistance applied downward on the superior shoulder.
• B. Sitting with the shoulder flexed to 90 degrees and palm down; stabilization by opposite scapula.
• C. Prone with the trunk weight on the table.
• D. Sidelying with the arm supported and the elbow flexed.

Answer: (A)

In scapular elevation testing against gravity, you want to isolate the upward movement of the scapula driven by the upper trapezius and elevator scapulae. The best setup is seated with the arms at the sides, having the patient shrug the shoulders upward (elevate the scapula toward the ears) while you provide downward resistance on the top of the shoulder. Stabilization comes from the patient maintaining the position and resisting movement, so gravity challenges the elevation but the scapula remains in place rather than shifting or rotating. This configuration specifically tests the strength of the elevation mechanism against an anti-gravity load. Other positions don’t isolate this motion. Elevation with the shoulder flexed to 90 degrees engages additional muscles and movements beyond pure scapular shrug. Prone with the trunk weight on the table changes the weight-bearing context and often emphasizes stabilization or different scapular actions. Sidelying with the arm supported and elbow flexed alters the movement pattern and doesn’t reproduce the standard anti-gravity scapular shrug.
