In the lower extremity D1 flexion pattern, which combination of hip movements is performed?

In the lower extremity D1 flexion pattern, which combination of hip movements is performed?

• 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 a combination of flexion, adduction, and external rotation. This diagonal pattern brings the leg upward and across the body with the foot turning outward. The other movement combinations correspond to different patterns (for example, extension with abduction and internal rotation, or flexion with abduction plus internal rotation), so they don’t match the D1 flexion pattern.
