Week 8 Flashcards
What joint does dorsiflexion and plantarflexion occur?
Talocrucal joint
What joint does inversion and eversion occur at?
Subtalar joint
What is sprained in a high ankle sprains?
Anterior inferior talofibular ligament.
What makes up the forefoot, midfoot and rear foot?
Forefoot- metatarsals and phalanges.
Midfoot - Navicular bone, the cuboid bone and 3 cuneiform bones.
Rearfoot - Talus and calcaneus.
Why there is greater ankle stability when we are in dorsiflexion?
Talus is wider anteriorly than it is posteriorly and there is less movement at the ankle motus.
What does the transverse arch span?
It is perpendicular to the longitudinal arch and spans the midfoot region and head of metatarsals.
What is a pes cavus foot and why is it bad?
It means the person has a high arch, their foot is very rigid and is painful as it doesn;t absorb a lot of force.
What is a pes planus foot?
A flat foot and while the foot is more mobile than a pes cavus foot - painful because the forces cannot be distributed properly.
Which way does the tibia rotate when the foot is supinated and pronanted?
Supinated - external tibial rotation.
Pronated- internal tibial rotation.
When is the foot in supination in the gait cycle?
During toe off- when heel makes contact with the ground.
What it the pathway of the ground reaction force?
Lateral and medial.
How many degrees of ROM do you need for ankle dorisflexion to prevent overuse injuries?
10 degrees.
What is the consequence of having weak intrinsic foot muscles?
Reduced motor control and propioception.
What are some signs and symptoms following a contusion and acute compartment syndrome to the lower leg? Why is it a medical emergency?
Foot Drop Cold Foot Numbness and Tingling Shiny Look Swollen
Compromises neuromuscular structures.
Is chronic acute compartment syndrome a medical emergeny?
No - comes and goes and with rest the symptoms subside.
