Which rocker is associated with toe off or pre-swing?

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

Answer: (D)

Forefoot rocker is the mechanism that enables toe-off and pre-swing. In late stance, the heel rises and the body’s weight shifts onto the forefoot, with the metatarsal heads acting as the pivot. The ankle plantarflexes and the toes extend, allowing the foot to roll over the forefoot and propel the body forward into the next swing. This differs from the heel rocker, which describes the initial contact rolling over the heel, and the ankle rocker, which describes tibial progression over a relatively fixed ankle during mid-stance. So toe-off and pre-swing are dominated by the forefoot rocker.
