During terminal stance, the ankle is approximately in what position?

• A. 15-20° plantarflexion
• B. 0°
• C. 5° plantarflexion
• D. 10° dorsiflexion

Answer: (D)

During terminal stance the body is progressing over the stance foot, with the heel rising and the weight shifting toward the forefoot. The ankle moves into dorsiflexion to about 10 degrees as the tibia advances over the foot. This dorsiflexed position allows proper forward progress, lengthens the plantarflexor muscles so they can control tibial advance eccentrically, and sets up the foot for the upcoming toe-off. As you move into the next phase, the ankle then plantarflexes to generate push-off.
