Below Knee Prosthetics
Prosthetic feet that have no heels and no footshells, many referred to as "running blades," would only be appropriate to provide to a patient who has been assigned a K-level of _____.
K4
With new bilateral AK amputees, what is the name of the bilateral prosthesis design are they fit with first?
Stubbies
This type of pain after an amputation is often described as cramping, squeezing, aching, or burning and can vary from mild to severe, sometimes benefiting from mirror therapy or graded motor imagery.
Phantom limb pain
This amputation level accounts for 90% of all UE amputations.
Partial hand amputations
In a transtibial socket, sometimes localized pressures are utilized. Name TWO sites are most often considered pressure-tolerant?
- Posterior popliteal
- Medial tibial flare
- Interosseous area between tibia and fibula
What type of prosthetic knee provides maximum stability, reducing the risk of falls? It is a simple design and very durable.
Manual locking knee
Which prosthetic interface is mainly used as a result of volume fluctuations within the socket?
Prosthetic socks
Which upper extremity prosthesis type typically results in a heavier device?
Myoelectric/Externally powered
Your transtibial patient has just bought cute new shoes and was super excited to tell you about them (since her prosthetic foot fit in them). They definitely look different than her previous pair, and not surprisingly, she also complains of a feeling that her knee buckles during gait (which is clearly observable). What has happened?
The new shoes have a higher heel than the old ones.
Which type of prosthetic knee uses accelerometers and gyroscopes?
Microprocessor knee
What post-op device is sometimes used with new BK amputees to prevent knee flexion contractures and protect the residuum's distal end?
Removable Rigid Dressing
The most anatomically accurate, visually appealing, and inconspicuous upper extremity prostheses are typically of which type of control system?
Passive
Which transtibial suspension method can offer audible feedback for the patient to be confident that their prosthesis will not fall off?
Pin locking suspension
Which transfemoral socket utilizes a “bony lock” to prevent movement of the pelvis over the socket during midstance?
Ischial containment
In lower extremity amputees, strength in this muscle group is crucial for knee stability in the sagittal plane during gait, while strength in the hip abductors aids in weight-bearing and frontal plane stability.
Hip extensors
In this type of cable-operated prosthetic control, the terminal device is closed at rest and opens when the patient pulls on the cable, with a spring or rubber band providing tension to close it again when relaxed.
Voluntary opening
The majority of the transtibial patients that you will see in the physical therapy clinic will have the a socket design most closely resembling which design?
a total surface bearing (TSB) design
Use of a hip joint and pelvic band for transfemoral prosthetic suspension is rare, but would be most ideal when a patient is observed to have what deficiency on the prosthetic side?
weak hip abductors
This exercise involves standing on a clock face and shifting weight to various ‘times’ without hand support, helping the patient learn the position of the prosthetic foot in relation to weight-bearing.
Proprioception training
For this level of amputation, a 'screwdriver shape' prosthetic socket provides transverse plane control, and anatomical suspension may or may not be used based on the trimline design.
Transradial/wrist disarticulation socket
