ankle/foot assignment

Question 1

Why is peroneus tertius innervated by the deep peroneal nerve instead of the superficial like the other lateral leg muscles?

Peroneus tertius crosses the ankle anteriorly and receives innervation with the other anterior muscles.
That is not the innervation
Peronius tertius is a two joint muscle
Peroneus tertius crosses the ankle posteriorly

Answer 1

Peroneus tertius crosses the ankle anteriorly and receives innervation with the other anterior muscles.

Question 2

During the ankle plantarflexion MMT test, when do you stop counting heel raises?

When the patient is unable to raise the heel from the floor consecutively through the max PF range every 2 seconds
Once the patient completed 1 heel raise without support
Once the patient feels confident enough to complete the PF without UE support
Once the patient reaches 25 reps, regardless of range

Answer 2

When the patient is unable to raise the heel from the floor consecutively through the max PF range every 2 seconds

Question 3

How are all of the MMTs for inversion and eversion grade 2s different from the MMTs we have learned for the hip and knee?

Grade 2 is partial ROM in gravity minimized
Grade 2 is full ROM against gravity
Grade 2 requires minimal resistance against gravity
Grade 2 is partial ROM against gravity

Answer 3

Grade 2 is partial ROM against gravity

Question 4

What is one major muscle of the lower leg that is considered a two-joint muscle?

Peroneus brevis
Soleus
Gastrocnemius
Flexor hallcus longus

Answer 4

Gastrocnemius

Question 5

When measuring ankle DF, positioning is important to avoid passive insufficiency . Which muscle is of concern and what position is required to prevent passive insufficiency?

Anterior tib/knee extended
Soleus/ knee flexed
Gastroc/ knee flexed
Anterior tib/ knee flexed

Answer 5

Gastroc/ knee flexed

Limit eversion

Answer 12

Prevent lateral displacement of the talus

Question 13

Which nerve innervates the gastrocnemius and soleus?

Deep fibular
Tibial
Superficial fibular

Answer 13

Tibial

Question 14

The tibialis posterior passes under the:
