Exam 1: Prosthetic Feet Flashcards
The type of prosthetic foot used is based on the _____ level of the patient
functional
True or False:
How the foot functions does not influence how the proximal kinetic chain functions
false
(Medicare/Medicaid) has established functional levels that LE amputees fall into for determining medical necessity for components of the prosthesis
Medicare
What are the categories of patient level that Medicare established based on
current and potential functional abilities
When will Medicare cover the cost of a prosthesis
If the patient will reach or maintain a defined functional state within a reasonable time and is motivated to ambulate
The clinical assessment of rehab potential must be based on the ______ _____
classification system
How many categories are within the classification system
5 categories
K0-K4
Which category of the classification system would an amputee fall under if he or she does not have the ability or potential to ambulate or transfer safely with or without assistance and a prosthesis does not enhance their quality of life or mobility
K0
Which category of the classification system would an amputee fall under if he or she has the ability or potential to use a prosthesis for transfers or ambulation on level surfaces at fixed cadence. Typical of the limited and unlimited household ambulator
K1
Which category of the classification system would an amputee fall under if he or she has the ability or potential for ambulation with the ability to traverse low-level environmental barriers such as curbs, stairs or uneven surfaces. Typical of the community ambulator.
K2
Which category of the classification system would an amputee fall under if he or she has the ability or potential for ambulation with variable cadence. Typical of the community ambulator who has the ability to traverse most environmental barriers and may have vocational, therapeutic, or exercise activity that demands prosthetic utilization beyond simple locomotion
K3
Which category of the classification system would an amputee fall under if he or she has the ability or potential for a prosthetic ambulation that exceeds basic ambulation skills, exhibiting high impact, stress, or energy levels. Typical of the prosthetic demands of the child, active adult, or athlete
K4
Which category of the classification system would be typical of the limited and unlimited household ambulator
K1
Which category of the classification system would be typical of the limited community ambulator
K2
Which category of the classification system would be typical of the community ambulator who has the ability to traverse most environmental barriers and may have vocational, therapeutic, or exercise activity that demands prosthetic utilization beyond simple locomotion
K3
Which category of the classification system would be typical of the prosthetic demands of the child, active adult, or athlete
K4
True or False:
Bilateral amputees are not strictly bound by the classification system
True
Would a physician, PT, and prosthetist prescribe a prosthesis for a patient’s current level or potential level. Why?
potential level in order to save money
What are the four categories of prosthetic feet
- non-articulating
- articulation
- non-articulating dynamic response
- Dynamic response and energy storing
What type of prosthetic feet would be classified as non-articulating
SACH - Solid ankle cushioned heel
What K level would a non articulating foot fall under
K1
A non articulating, SACH foot is (low/high) maintenance
very low
Describe what would happen if an amputee with a non-articulating foot walked on uneven surfaces
With a non-articulating SACH foot, there is basically no accommodation or PF, so the entire leg with move to adjust to the ground since there are no ankle strategies available
If a patient was considered to be at a K1 level, what type of prosthetic feet would be prescribed
non articulating SACH
What type of prosthetic feet would be classified as articulating
single axis or multi axis feet
A single axis articulating foot allows up to ___ degrees of PF and ___ degrees of DF
15 PF
5-7 DF
Which type of articulating foot allows for 15 degrees of PF and 5-7 degrees of DF
single axis
A multi axis articulating foot has ____ for DF and PF and allows (no/some) inversion or eversion for accommodating to different surfaces
bumpers; some
What type of articulating foot has bumpers for DF and PF and allows some inversion and eversion
multi-axis feet
What types of prosthetic feet would be classified as non-articulating dynamic response
SAFE - stationary ankle flexible endoskeleton
Elastic Keel Feet
What category of prosthetic feet allows for storing of energy and then a release of energy
non articulating dynamic response
A dynamic response foot can be a (single/multiple) axial prosthetic
both
K__ level users get more use out of a dynamic response foot than other K levels
3
Which K level would be an household limited ambulator
1
True or False:
A K1 SACH foot as moving parts
false
Which K level would be a community limited ambulatory
2
Most feet fit for K2 level amputees are (lightweight/heavy), have a (flexible/rigid) heel, are (single/multi) axial, and provide some energy for return
lightweight, flexible, multi-axial
K3 feet are typically made of lightweight flexible _____ _____
carbon fiber
Microprocessor feet fall into what K level
K3
There are nearly ____ different designs available for K3 users
100
K__ level feet can adjust the heel height, have shock and torsion absorption, or may have hydraulic damping to improve sagittal plane fluidity
3
Microprocessor ankles adjust to PF and DF with _____ and ____.
inclines and declines
Microprocessor ankles adjust to ___ and ___ with inclines and declines
PF and DF
Some microprocessor ankles assist (DF/PF) torque needed from (anterior tib/gastroc) for propulsion
PF; gastroc
Which prosthetic foot is usually heavier and needs nightly charging
microprocessors
Can microprocessors be exposed to water, dirt, or extreme heat
no
Currently, microprocessors are (single/multiple) axis
single
A carbon fiber composite foot with energy storing dynamic response belongs to a level of K__
3
A high level child, athlete, or active adult would use a prosthetic foot that belonged to a K__ level
4
Which K level foot would be used for serious athletes and runners
4
True or False:
Prosthetics that are made for running and sprinting can also be worn for every day wear
false
Which K level foot would be appropriate for golfers and hikers
multi-axis K4
Which K level foot would be used for swimming or rock climbing
K4
Swimming feet can lock in (DF/PF) to aid in the activity
PF
It is important to select the proper foot because it could dramatically decrease ____ on the residual limb and sound limb
stress
