During loading response, the external knee moment is what?

During loading response, the external knee moment is what?

• A. Internal rotation
• B. Abduction
• C. Extension
• D. Flexion

Answer: (D)

In loading response, the force from the ground through the leg tends to bend the knee, so the external knee moment is a flexion moment. This phase is about absorbing shock as weight is borne by the limb, and the quadriceps work to counter that by creating an internal extension moment to control and gradually straighten the knee as stance continues. Abduction, internal rotation, or pure extension moments aren’t the dominant tendency during this phase.
