Which combination describes the shoulder movements in the D2 flexion pattern of PNF?

• A. Shoulder flexion, abduction, external rotation
• B. Shoulder extension, adduction, internal rotation
• C. Shoulder flexion, adduction, internal rotation
• D. Shoulder flexion alone

Answer: (C)

In PNF, the D2 flexion pattern is a diagonal shoulder movement that combines three components: flexion, adduction, and internal rotation. This pattern moves the arm upward toward the midline while the humerus internally rotates, creating a diagonal arc often described as bringing the hand from a lower, lateral position toward the upper, medial region of the body. That combination—flexion with adduction and internal rotation—best matches the described D2 flexion pattern.

The other options don’t fit because they either add a component not included in this pattern (such as abduction with external rotation) or describe a different movement direction (extension rather than flexion) or omit one of the key components of the diagonal.
