What is the fulcrum point for the Shoulder Flexion test?

• A. Lateral greater tubercle.
• B. Anterior acromial.
• C. Lateral midline of humerus.
• D. Midline of sternum.

Answer: (A)

When measuring shoulder flexion with a goniometer, place the axis at the center of rotation of the humerus as it moves at the shoulder joint. The best landmark for this axis is the lateral aspect of the greater tubercle of the humerus. This location tracks the actual glenohumeral joint rotation during flexion, giving an accurate reading of how far the arm can raise in front of the body.

The other landmarks described aren’t the axis for this movement: one describes where the moving arm should align, another describes where the stationary reference should sit on the trunk, and the remaining option isn’t the axis used to capture shoulder flexion.
