UE Prosthetics Flashcards
(16 cards)
2 most common UE amputation causes
trauma (75%)
disease
how does a bilateral vs unilateral UE prosthetic user differ?
uni: use prosthetic as AD
bi: use prosthetic more
which level of UE amputation is more functional with their prosthetic?
bilateral below elbow
Perks of wrist disarticulation
Can WB on end
Has sensation
Advantages of function/cosmetic UE prosthetic
- cosmetic
- light weight
- simple
- little maintenance
- inexpensive
- great for partial hands
- PROVIDES OPPOSITION
Disadvantages of function/cosmetic UE prosthetic
- NO ACTIVE PREHENSION
- limited function
- decreased durability
- unreal expectations from cosmesis
- custom silicone very expensive
Prosthetic components, such as terminal devices, are operated by _____ system
Harness which is controlled by gross body movements
Advantages of body-powered prosthetic
Proprioception
Lighter weight
Disadvantages of body-powered prosthetic
- limited grip force
- ROM (function envelope) limited
- possible over-use, nerve entrapment
Typical type of harness for transradial amputations
Single-control system
Typical type of harness for transhumeral amputations
Double-control & triple-control harness
Pinch force strength is determined by ____ for voluntary closing terminal devices
Wearer
Pinch force strength is determined by ____ for voluntary opening terminal devices
Rubber bands or springs
Advantages of myoelectric/external power
- greater function envelope
- greater grip strength
- reduced or eliminated harness system
- increased cosmesis
Hybrid prosthetic includes ____ + ____
Body power + external power
Hybrid prosthesis advantages
- feedback of forearm flexion velocity
- greater ROM
- reduced weight
- greater grip strength
- Reduced harness system
