Which group correctly lists the three demands of swing limb advancement?

• A. Knee Locking, Hip Extension, Ankle Plantarflexion
• B. Lifting of the Foot, Completion of Stride Length, Preparation for Next Stance Interval
• C. Pelvic Drop, Pelvic Hike, Foot Slap
• D. Shock Absorption, Limb Stability, Preservation of Progression

Answer: (B)

During swing, the leg must advance in a way that keeps you moving smoothly and safely forward. The first requirement is lifting the foot to clear the ground, which prevents tripping as the leg swings under you. The second is completing the stride length, meaning the leg travels far enough forward to set up the next step and maintain steady progression. The third is preparing for the next stance interval, so the foot lands in the right position for a stable heel strike and weight acceptance. The other options describe actions more tied to the stance phase or to abnormal gait signs. Knee locking, hip extension, and ankle plantarflexion are classic elements of push-off and weight bearing rather than the forward clearance and placement tasks of swing. Pelvic drop, pelvic hike, and foot slap are gait abnormalities or compensations rather than the fundamental demands of advancing the limb during swing. Shock absorption, limb stability, and preservation of progression relate to how the body handles contact and stability in stance, not the primary aims of swing limb advancement.
