During terminal stance and pre-swing, the external hip moment is what?

During terminal stance and pre-swing, the external hip moment is what?

• A. Abduction
• B. Extension
• C. Dorsiflexion
• D. Flexion

Answer: (B)

During terminal stance and pre-swing, the leg trails behind the body and the ground reaction force acts behind the hip joint. This positioning tends to rotate the thigh in the direction of extension, producing an external hip extension moment. The hip extensors work to control and propel the limb during this phase. Abduction or dorsiflexion describe movements at other joints or planes, and flexion would be the opposite direction of the observed torque at the hip in this part of the gait cycle.
