The Subtalar Joint [Part 2] | Pronation vs Supination EXPLAINED

The video tutorial explains the movements at the subtalar joint, focusing on inversion, eversion, supination, and pronation. It distinguishes between simple and composite movements, describes the subtalar joint's anatomy, and discusses the functional implications of these movements in activities like walking and exercising. The tutorial also covers the concept of subtalar joint neutral and the differences between open and closed chain movements.

What bones form the subtalar joint?

• Talus and tibia

• Talus and calcaneus

• Calcaneus and fibula

• Tibia and fibula

Which movements are primarily associated with the talocrural joint?

• Abduction and adduction

• Dorsiflexion and plantarflexion

• Supination and pronation

• Inversion and eversion

What is the main difference between inversion and eversion compared to supination and pronation?

• Inversion and eversion are composite movements

• Supination and pronation are simple movements

• Inversion and eversion are simple movements

• Supination and pronation involve only one movement

How can you determine if someone is in subtalar joint neutral?

• By measuring the angle of the ankle

• By checking if the foot is flat on the ground

• By ensuring the midline of the calf and calcaneus are parallel

• By observing the arch of the foot

What happens to the tarsal bones in a pronated state?

• They move closer to the midline

• They become more rigid

• They lock together

• They separate and become more mobile

Which state of the foot is better for shock absorption?

• Supinated

• Inverted

• Neutral

• Pronated

During which part of the gait cycle is the foot typically supinated?

• Initial contact

• Toe off

• Loading response

• Mid stance

In closed chain supination, what movement does the talus undergo?

• Inversion and eversion

• Plantarflexion and adduction

• Internal rotation

• Dorsiflexion and abduction

What is the effect of calcaneal inversion in a supinated state?

• The talus adducts

• The ankle collapses laterally

• The tibia internally rotates

• The ankle collapses medially

In closed chain pronation, how does the tibia move?

• Externally rotates

• Internally rotates

• Moves laterally

• Moves anteriorly
