UE Proesthetic Overview Flashcards
What are teh 2 most common UE amputation casues
- trauma
- disease
75% of UE amputations in adults are caused by ___
Trauma
How does a unilateral used of a UE prosthetics usually use it primarily
As an assistive device , doing most ADLS one handed with sound limb
How does a bilateral user of a UE prosthetics usually use it primarily
Uses it more due to need , the below elbow user will be more function than a higher level due to better positioning
Will a above the elbow or below the elbow amputation use prothestics more functionally
Below
What are the preferred levels for UE amputation
Above or elbow the elbow
What are the choices of prosthetics for UE
• No Prosthesis
• Passive Functional / Cosmetic
• Body Powered / Conventional
• Myoelectric / External Power
• Hybrid
• Adaptive
What are advantages of a passive functional/ cosmetic prosthetic (7)
- Cosmetic
- Lightweight
- Simple
- Little Maintenance
- Inexpensive (NON-custom silicone)
- Great for Partial Hands
- Provides Opposition
What are disadvantages of a passive functional/ cosmetic prosthetic (5)
- No Active Prehension
- Limited Function
- Decreased Durability
- Unreal Expectations for Cosmesis
- Custom Silicone Very Expensive
Components on the prethesis , such as the elbow and terminal device are operated by a ___ system… this system is controlled by what
Harness
Gross body movements
What does a single control harness do
Operates teh terminal device
What are advantages of a body powered prothestics (5)
- Heavy Duty Construction
- Proprioception
- Less Expensive
- Lighter in Weight
- Reduced Cost and Maintenance
What are disadvantages of a body powered prothestics (5)
- Grip Force is Limited (shoulder strength and
rubber band tolerance) - Functional Envelope (ROM) is Limited
- Harness Can be Uncomfortable and
Restrictive - Poor Cosmesis
- Possible Over-Use, Nerve Entrapment
Syndrome
What are the typical systems for transradial fitting for a harness
Single control systems
What are the typical systems for a transhumeral fitting for a harness
- double control harness
- triple control harness
What is the double contrl harness
- has 2 control cables
- activation of terminal device and control of forearm flexion
- elbow joint lock/relseae
What are advantages of myoelectric / external power prosthetics (4)
- Greater Functional Envelope
- Increased Cosmesis
- Greater Grip Force
- Reduced or Eliminated Harness System
What are disadvantages of myoelectric / external power prosthetics (4)
- Increased Cost and Maintenance
(initially) - Increased Weight (typically)
- Battery
- Environmental Interference
What are advantages of hybrid prosthesis(6)
- Greater Functional Envelope
- Reduced Weight
- Greater Grip Force
- Reduced Harness System (greater comfort and improved
ROM) - Feedback of Forearm Flexion Velocity
- Reduced Initial and Maintenance Costs
What are disadvantages for a hybrid prosthesis
- Control Harness Typically Required
- Increased Weight on Harness
What enables ur brain to control prosthetic limbs
Targets mm reinneravtion
What are the futures things when combining OI with technical advances
- targeted mm re innervation
- pattern recognition
- implantable electrodes
- sensory feedback
