Foot & Ankle Flashcards
(20 cards)
1
Q
Sach Foot
About
A
- Heel compresses during LR
- Simulates PF to get foot flat
- Replace function of DF muscles during LR
2
Q
Single Axis
About
A
- Allows passive PF and DF
- increased knee stability during loading response
- reduced knee flexion moment
3
Q
A
4
Q
Flexible Keel
About
A
- Forefoot ev/inversion
- improve transition to ipsilateral side in TS
5
Q
Multiaxial
About
A
Motion in 2+ Planes
6
Q
ESAR
About
A
- Provides sense of push off
- Heel Spring: Simulates PF Shock Absorption
- Keel Spring: Deflects under load
7
Q
SACH
Advantages
A
- Low maint
- various heel heights
- decreased KF moment
- rigid keel = stabilization @ Mst encourage KF want body to go forward
8
Q
Single Axis
Advantages
A
promotes sagittal plane knee stability
9
Q
Flexible Keel
Advantages
A
- smooth rollover properties
- forefoot eversion/inversion
10
Q
Multiaxial
Advantages
A
- Sagittal: PF increaes knee stability at LR; DF soften rollover in LS
- Coronal: uneven terrain
- transverse: absorption of rotation
11
Q
ESAR
Advantages
A
- reduced energy expenditure
- reduced impact of cyclic vertical load
- low weight if carbon
12
Q
SACH
Disadvantages
A
- deterioration of soft material
- no coronal plane “ground compliance”
13
Q
Single Axis
Disadvantages
A
- maintenanc edur to articulating components
- heavier
14
Q
SACH
Indications
A
- limited ambulators
- children
- bilateral
15
Q
Single Axis
Indications
A
- Weak Quads (TT)
- limited ambulator
- weak extensors (TF)
16
Q
Multiaxial
Indications
A
- golfer
- uneven ground
17
Q
ESAR
Indications
A
- @ risk for overuse injury
- walk @ variable cadence
- community ambulators
18
Q
Single Axis
contraindication
A
- do not use w/ stance flexion knee
19
Q
Multiaxial
Contraindications
A
- lower K level cant control conronal plane
- too flexible
20
Q
ESAR
Contraindications
A
- weak quads or extensors (Push them forward)
- unstable
