Q

How much ROM do you need at the big toe for normal gait? and what results if not normal?

A

Need 60 deg for push off

less than 45 results in less rocker at the foot

0-120

23
Q

ROM goals for hip?

A

10-0-100

24
Q

What is Osseo-integrated fixation?

A

metal pylon goes right into bone, allows for vibratory sense and has best ABC score and balance

25
Q

When do you add a sock?

A

when limb shrinks

or when there’s red marks inferior border of patella or fibular head.

26
Q

When do you take off sock?

A

limb is not in socket enough

or when there’s red marks on tibial tubercle, or fib head

27
Q

Fitting needs during sitting?

A

clear hamstrings

28
Q

Fitting needs during standing?

A

good patella orientation

clear lateral walls and pressure points

29
Q

Excessive knee flexion can be due to what three things?

A

excessive DF
excessive ant socket over foot
excessive stiff heel/cushion
flexion contracture***

30
Q

lacking knee flexion can be due to what 5 things?

A 
excessive PF
excessively post socket over foot
excessive soft heel/cushion
anterior/distal discomfort
weak quads
habit****
31
Q

excessive lateral thrust can be due to what 2 things?

A

excessive medial placement of prosth foot

abducted socket

32
Q

What does ABC score stand for?

A

Activities-specific Balance Confidence

A

3.4

34
Q

What is MDC for TUG?

A

3.6 sec

35
Q

What assessment correlates with K level for Medicare?

A

AMP

36
Q

What is K0?

A

no potential to ambulate therefore no prosthesis

37
Q

What is K1?

A

limited potential for ambulation used for transfers

38
Q

What is K2?

forward progression
stance stability
energy conservation

42

A

heel: absorption
ankle: transition
forefoot: propulsion

43
Q

narrow base gait can be due to what 2 things?

A

excessive medial placement of prosth foot

improper lateral tilt of socket

44

Pistoning is due to what?

A

loss of suspension

45
Q

Abducted gait is due to what?
