During a lower extremity D1 flexion PNF pattern, what movements are taking place at the hip?

• A. Flexion, adduction, external rotation
• B. Extension, abduction, internal rotation
• C. Flexion, abduction, internal rotation
• D. Flexion, adduction, internal rotation

Answer: (A)

In the lower-extremity D1 flexion pattern, the hip moves into flexion while the thigh adducts (moves toward the midline) and externally rotates. This combination—flexion plus adduction with external rotation—defines the D1 flexion direction for the leg and mirrors a diagonal flow used in functional tasks like bringing the leg up and across the body. This pattern contrasts with the other option pairs because those either omit flexion, add abduction (moving away from midline), or use internal rotation (the opposite of external rotation). Therefore, flexion with adduction and external rotation is the correct hip movement for this pattern.
