Oblique axis that forms a 42° angle in the vertical plane and 16° in the horizontal plane

Front 12

True or False: motion at the subtalar joint can be described as being triaxial.

Back 12

False, it is triplanar

Front 13

True or False: Rearfoot pronation is associated with internal rotation of the tibia.

Valgus

Front 15

True or False: During open chain subtalar motions the talus is stable.

Back 15

TRUE

Front 16

True or False: During closed chain subtalar motions the forefoot is stable.

Back 16

TRUE

Front 17

True or False: during closed chain subtalar pronation the talus adducts and plantarflexes.

Back 17

TRUE

Front 18

True or False: during open chain subtalar supination the forefoot abducts and dorsiflexes.

Front 20

True or False: a person with excessive pronation has a decreased medial longitudinal arch.

Back 20

TRUE

Front 21

What role do the arches of the foot play?

dissipating forces, adjusting to changes in terrain and propelling body forward.

Back 24

TRUE

Front 25

Back 25

TRUE

Front 26

Back 26

L4-5

Front 27

Describe the arthrokinematics of closed chain plantarflexion.

Back 27

The tibia rolls and glides posteriorly

Front 28

What nerve roots innervate the Gastrocnemius?

Back 28

S1 and S2

Front 29

Decribe why ankle dorsiflexion is more stable then plantarflexion.

Back 29

Since the anterior aspect of the talus is wider than the posterior aspect, during DF the anterior aspect fits between the malleoli thus creating a "wedging" effect
