Overlapping (converging); mobility
Overlapping (converging); stability
Parallel; mobility
Parallel; stability
Overlapping (converging); stability
Your patient demonstrates decreased open-chain pronation at the subtalar joint. Which of the following would be limited?
Adduction of the calcaneus on the talus
Both A and C
Plantarflexion of the calcaneus on the talus
Eversion of the calcaneus on the talus
Eversion of the calcaneus on the talus
You observe that your patient has excessive flattening of the medial longitudinal arch. You hypothesize that the excessive flattening is due to excessive lengthening of the ligaments that support the medial longitudinal arch. Which of the following structures would be excessively lengthened?
Calcaneofibular ligament
Posterior talofibular ligament
Cervical ligament
Spring ligament
Spring ligament
Arch stability in the foot is maintained by the following structures
Tarsal bones, ligaments and muscles
Ligaments
Ligaments and muscles
Tarsal bones and ligaments
Tarsal bones, ligaments and muscles
Supination twist refers to a midfoot motion needed to maintain
The 1st toe in contact with the ground
Optimal alignment of the talus and calcaneus during push off
The 5th toe in contact with the ground
Optimal alignment of the talus and calcaneus during heel strike
The 5th toe in contact with the ground
Which of the following statements best describes the windlass mechanism of the plantar aponeuroses (fascia)?
Active tension causes the axes of the midtarsal joints to become more parallel at push-off.
Passive extension of the big toe causes the medial longitudinal arch to elevate.
Active tension on the lateral calcaneus causes the lateral longitudinal arch to elevate.
Passive flexion of the big toe causes the medial longitudinal arch to elevate.
Passive extension of the big toe causes the medial longitudinal arch to elevate.
Which of the following muscles supports the lateral longitudinal arch?
Flexor hallucis longus
Abductor hallucis
Posterior tibialis
Peroneus/fibularis longus
Peroneus/fibularis longus
