1

What may cause foot drop with a forefoot-heel contact?

common fibular nerve palsy and peripheral neuropathy
- this results in very weak DFs and/or pes equinus

2

T/F: There is no active dorsiflexion during swing for a foot drop with forefoot-heel contact.

true, just passive DF during stance, no active DF during swing

3

Why would one have a foot flat gait?

common fibular nerve palsy and peripheral neuropathy

4

What does the deep fibular n. innervate?

anterior compartment of leg (DFs)

5

What does superficial n. innervate?

lateral compartment of leg (everter/PFs)

6

What can cause a foot slap or drop?

weak DFs from common fibular nerve palsy or peripheral neuropathy

7

What major issues may follow at the ankle with a common fibular nerve palsy or peripheral neuropathy?

- foot slap/drop
- flat foot
- foot drop with forefoot heel contact
* all these are issues with the DFs

8

What are some ways we can compensate to help clear the floor?

hip hike, circumduct, vault, more KF/HF/DF

9

What likely impairments cause a forefoot-delayed heel contact gait?

spastic PFs or PF contracture; pes equinus

10

What happens at the tibia with a forefoot-delayed heel contact gait?

it needs to be thrust backwards to get the foot down, so you go into a good amount of extension at knee

11

What likely impairments occur with a foot flat gait?

- markedly weak DFs, knee flexion contracture, overactive hamstrings

12

What pathological precursors can cause a forefoot-delayed heel contact gait?

UMN lesion, CP, CVA

13

Why would someone be a toe walker?

- due to calcaneal pain
- upper motor neuron lesion, CP, CVA causing PF contracture or PF spasticity

14

What does a crouched gait look like?

may present in a toe walker: HF, KF, PF

15

What other excessive motions may accompany plantar flexor weakness during gait?

hip flexion and knee flexion
- no PF = no tibia control, causing more KF

16

Delayed heel rise is due to what deformity?

weak PFs, due to peripheral or CNS disorders
- or lengthening of Achilles tendon

17

What happens to gait when you have weak PFs?

no push off, shortened step length, prolonged heel contact

18

What can cause lateral foot weight bearing?

a supinated foot position (pes cavus) due to SCI, congenital structural deformity

19

With what gait deviation may you see reduced midfoot mobility?

lateral foot weightbearing

20

Dynamic excessive pronation can be due to a weak ___________ muscle.

tibialis posterior

21

In dynamic excessive pronation, the foot stays pronated too long in what stance?

midstance: should be moving from pronation to supination here and it doesn't

22

What can cause static excessive pronation?

floppy foot can be caused by paralyzed inverters or pes planus deformity
- can be due to UMN lesion or congenital structural deformity

23

T/F: Subtalar joint is constantly everted with a floppy foot.

true

24

During what phase of gait does vaulting present?

midstance

25

An overall excessive internal rotation of the lower extremity in stance can be seen in what gait deviation?

floppy foot, or static excessive pronation

26

Why might someone present with a backward lurch during their gait?

to bring the LoG posterior to help the gluts not work as hard, they may be paralyzed or weak
- decreases forward progression of body
- this lurch can also help bring the swing limb forward

27

Excessive toe out can be caused by what bony alignment issue?

retroversion

28

Inadequate knee flexion affects what stages?

loading and most of swing phases

LR = no shock absorption
PSw = toe off is difficult
ISw = dragging toe here
MSw = continued toe drag

29

What can cause a knee extensor thrust?

upper motor neuron lesion causing spastic quads

30

What can cause weak quads?

UMN lesion, femoral nerve palsy, arthritis pain, L3-4 compression neuropathy
