Flashcards in 04 Foot Exam 4 Deck (27):
1

common foot types

- rigid rearfoot, rigid forefoot
- rigid rearfoot, flexible forefoot
- stable rearfoot, stable forefoot
- flexible rearfoot, flexible forefoot
- flat rearfoot, flat forefoot

2

What is STJ neutral?

position of congruency between talus and calcaneus

3

rearfoot exam: patient position

- figure 4
- PF of foot on medial knee

4

How to find STJ neutral position

- grasp talus
- provide slight DF at head of metatarsals 4 and 5
- make sure you don't bias the alignment of the foot
- you're in neutral STJ position when head and dome of talus are no longer prominent

5

Why apply DF pressure when finding STJ neutral?

simulate neutral stance phase of gait cycle

6

Alternative method to finding neutral STJ

- take STJ to full INV/EV
- back off either 2/3 from INV or 1/3 from EV

7

STJ neutral in WB: calcaneus position

perpendicular to transverse plane

8

STJ neutral in NWB (prone): calcaneus position

perpendicular to frontal plane

9

subtalar joint: calcaneus position

normally has 2-4˚ varus

10

measuring calcaneal varus

- bisect posterior calcaneus
- compare to bisection of lower 1/3 of tibia

11

midtarsal joint: normal

STJ neutral

12

midtarsal joint: normal forefoot should be at this position

- 0˚
- directly perpendicular to bisection of the calcaneus
- must measure with STJ in neutral

13

testing the midtarsal joint

- passive mobility testing to adduction and abduction
- qualitative assessment of SYMMETRY of movement
- should have symmetrical PROM

14

Chopart's joint

midtarsal joint between talus/calcaneus and navicular/cuboid

15

Lis Franc's joint

tarsometatarsal joints

16

What position should you evaluate the forefoot in?

prone

17

Measuring forefoot position

- start with rearfoot in neutral
- evaluate the forefoot relative to neutral rearfoot

18

first ray mobility testing

should be parallel to other metatarsal heads with fourth ray loaded in STJ neutral

19

ECPP

excessive compensatory prolonged pronation

20

ECPP: what is it?

- excessive pronation
- staying in pronation for a longer time during gait cycle instead of resupinating)

21

foot mechanics: high arch

underpronation/supination

22

foot mechanics: medium arch

- neutral position
- mild overpronation

23

foot mechanics: flat arch

- severe overpronation

24

shoe recommendation: high arch

neutral

25

shoe recommendation: medium arch with neutral pronation

neutral or stability

26

shoe recommendation: medium arch with mild overpronation

stability or motion control

27

shoe recommendation: severe overpronation

motion control
