Study Notes
- The ankle plantarflexes and dorsiflexes twice during the gait cycle.
- The ankle rapidly plantarflexes during loading response.
- The ankle is in about 10° of dorsiflexion by the end of midstance.
- The foot dorsiflexes to neutral or slight dorsiflexion during swing phase.
- The greatest amount of plantarflexion and dorsiflexion both occur during the stance phase.
- The metatarsophalangeal joints hyperextend during the stance phase.
- The MTP joints reach their maximum motion, 55° to 60°, by the end of preswing.
- Hyperextension of the MTP joints is maintained at about 30° to 40° during swing phase.
- Pain or restriction of motion of the MTP joints can have devastating effects on the ability to walk.
- The ankle close-packed position is 10° of dorsiflexion.
