Which sequence correctly describes the three rockers from heel strike to forefoot?

• A. Heel rocker, Ankle rocker, Forefoot rocker
• B. Forefoot rocker, Heel rocker, Ankle rocker
• C. Ankle rocker, Forefoot rocker, Heel rocker
• D. Heel rocker, Forefoot rocker, Ankle rocker

Answer: (A)

In gait, the foot uses three rockers to allow smooth forward progression, each defined by a different part of the foot acting as a fulcrum. The sequence begins with the heel contacting the ground and the tibia moving forward over the fixed calcaneus, which is the heel rocker. As the stance leg continues, the ankle itself becomes the pivot point, letting the tibia advance over the ankle joint—that's the ankle rocker. Finally, as weight shifts onto the forefoot and the heel rises, the forefoot and toes form the pivot, enabling the push-off—the forefoot rocker. Therefore, from heel strike to forefoot, the order is heel rocker, then ankle rocker, then forefoot rocker.
