Q

What paper gives overview to the function of the foot arch, windlass mechanism and flat vs rigid feet?

A

Behling, 2023

17
Q

Whole foot pronation consists of what three movements ?

A
  1. Rear foot eversion
  2. Forefoot abduction
  3. Forefoot dorsiflexion
18
Q

Nielsen, 2013 paper gives support to what?

A

That foot pronation is not consistently linked to injuries

19
Q

What nerve may be injured with a lateral Mal. Fracture?

A

Superficial peroneal nerve

20
Q

True or false: the PIM contribute greatly to resist long arch deformation during weight acceptance ?

21
Q

When do the PIM become important in the gait cycle and how do they contribute?

What paper supports this notion

A

They are important in stiffening the forefoot during late stance just prior to push off

As found by Farris 2019

22
Q

Inhibition of the PIM does what to the foot during

A

Decline in power output during push-off

23
Q

What two PIM are most important for the active contribution to the LA

24
Q

What role do the PIM play in relation to the MTP joint and gait

A

They actively stiffen to 1st MTP in late stance - this assists in propulsive power during push off

25
What effect does barefoot running have on foot strike
Generally a shift towards mid and forefoot strike is more likely
26
A Baxter neuropathy is compression or which nerve?
ICN
27
What muscle does the ICN innervate?
Abductor digiti minimi
28
What nerves are involved in Morton’s neuroma ?
Common digital nerves - usually between the third web space
29
What is Tarsal Tunnel Syndrome?
Entrapment of the Tibial nerve around the medial flexor retinaculum
30
Tarsal Tunnel syndrome may refer symptoms where?
