Q

What are the Ottawa Ankle rules?

A
  • Find out MOI and gauge pt’s ability to bear weight within the first hour of injury
  • Begin palpation in neutral site (forefoot)
  • Palpate for bone tenderness
  • Posterior edge of malleoli
  • 5th metatarsal (prox tip to base)
  • navicular
  • distal 6 cm of fibula
  • When bone tenderness is absent, have the pt take 4 steps, 2 with each foot. If they can’t do it, refer for radiograph
  • Have pt seek f/u care if pain doesn’t decrease and WB doesn’t increase after 5-7 days

Q

What are 5 variables you can change to make balance exercises easier/harder?

A
  • EO/EC
  • regular stance/tandem
  • SL/DL
  • even/uneven surface
  • steady/add perturbations
17
Q

What would you expect to see during a negative Windlass test?

A

arch elevates

18
Q

How do you measure LLD in standing?

A

ASIS to medial malleolus

19
Q

Why should we measure LLD in standing vs unloaded?

A
  • WB gives you info applicable to function

- unloaded doesn’t take into account recurvatum etc

20
Q

Is a LLD more impactful in the sedentary or active population?

A
  • active

- performing more impact activities that are altered with LLD, whereas sedentary individuals don’t

21
Q

In OKC, what are the arthrokinematics of the talocrural (ankle) jt?

A

convex on concave

22
Q

In CKC, what are the arthrokinematics of the talocrural (ankle) joint?

A

concave on convex

23
Q

Greater than 10 mm difference on Navicular drop test indicates

A

pronated foot

24
Q

When using the longitudinal arch angle test, what goniometric measurement is considered to be normal?

A

130-150˚

25
Q

What are the major landmarks used when measuring figure 8 anthropometrics?

A
  • anterior tib tendon
  • navicular tubercle
  • plantar surface of foot
  • cuboid groove
  • back to anterior tib tendon
  • distal to medial malleolus
  • proximal to calcaneal dome
  • distal to lateral malleolus
  • back to anterior tib tendon
26
Q

What is the taping procedure to help with arch support?

A

Low dye taping

27
Q

What common dx is low dye taping used for?

A

PF

28
Q

What is the procedure for 1st ray mobility testing?

A
  • long sitting
  • stabilize rays 2-5 with 1 hand and grasp 1st ray using the other
  • apply pressure in dorsal/plantar directions
29
Q

What should 1st ray mobility testing look like?

A

passive mobility should be a 1:1 ratio

30
Q

1st ray mobility: (+) finding

A

more mobility in plantar compared to dorsal direction

31
Q

1st ray mobility: implication of (+) finding

A
  • compensation for forefoot varus

- for the foot to reach the ground, it has to go farther than if it was in neutral

32
Q

What is the maximum internal shoe lift that can be used?1

A

1/2 inch

33
Q

What is the closed packed position of the ankle?

A

max DF

34
Q

What is the loose packed position of the ankle?

A

PF

35
Q

Name one test you can use to quantify the degree of pronation/supination that a pt has

A
  • Feiss’ line
  • navicular drop test
  • longitudinal arch angle
