Which statement correctly describes the toe-off phase?

Which statement correctly describes the toe-off phase?

• A. The foot transitions from heel to toe during late stance to promote forward progression.
• B. The ankle plantarflexes maximally during heel strike.
• C. The foot remains flat on the ground during late stance.
• D. The knee flexes excessively during toe-off.

Answer: (A)

Toe-off is the propulsion part of the stance phase, where the body moves from heel contact toward pushing off the toes. In this moment, the ankle plantarflexes and the forefoot bears weight as the heel rises, enabling forward progression. This is exactly what the statement describes: the foot transitions from heel to toe during late stance to promote forward progression. During heel strike, the ankle is not at maximal plantarflexion; the foot first contacts the ground with the ankle in dorsiflexion. The late stance phase does not keep the foot flat; the heel rises and weight shifts to the forefoot to push off. The knee does not flex excessively during toe-off; propulsion relies more on ankle plantarflexion and forefoot push-off than on large knee flexion.
