The swing limb advancement comprises which phases?

• A. Loading response
• B. Initial contact
• C. Pre-swing, initial swing, mid-swing, terminal swing
• D. Midstance and terminal stance

Answer: (C)

The swing limb advancement is about the forward progression of the leg from toe-off to the next heel strike, and it’s described in four subphases that capture how the leg moves to clear the ground and position for contact. This sequence starts with pre-swing, where weight shifts to the other leg and the swinging leg begins to move forward in preparation for toe-off. Then comes initial swing, when the hip and knee flex to start lifting the leg. Next is mid-swing, as the thigh moves forward and the leg clears the ground more fully. Finally, terminal swing, during which the leg extends and decelerates to ready the foot for heel strike. The other options describe periods when the foot is in contact with the ground and bearing weight (stance phases), so they don’t describe the forward-moving phases of the swinging leg. Including pre-swing along with the three swing subphases best matches how the leg progresses toward the next step.
