Flashcards in Prosthetics Deck (21):
1

Causes of UE amputations

Trauma
Congenital
Disease

2

Causes of LE amputations

largely a result of disease

3

What is the basic prosthetic goal generally?

Provide appropriate function and appearance to increase independence with ADLs and improve quality of life

4

What are some priorities and challenges for new amputees

Patient/caregiver education
Peer support
Delineate prosthetic expectations
Rebuilding proprioception
Establishing independence and confidence
Establishing good habits

5

Through evaluation process, we want to design a device that meets what kinds of needs?

Activities of daily living
Medical needs
Gainful employment/ Vocational need
Psychological need
Avocational needs
Specific tasks

6

Benefits of an oppositional prosthesis

Provides aesthetic appearance
Light weight & simple
Functions: Opposition, Holding objects, Restore body image
Proprioceptive feedback

7

Limitations of an oppositional prosthesis

No active prehension
High cost for custom
Durability
Patient can have unreal expectations for cosmesis

8

Prosthesis that relies upon gross body movements captured through a harness

body-powered prosthesis aka cable-driven

9

Benefits of a body-powered prosthesis

Moderate cost and weight
Durable
Environmentally resistant
Proprioception through harness system

10

Limitations of a body-powered prosthesis

Grip strength or pinch force
Restrictive & uncomfortable harness
Requires muscle power & excursion
Poor static & dynamic cosmesis

11

What body motions do you need to open the terminal device for a transradial amputation

Biscapular abduction & Humeral flexion

12

What body motions do you need to open the terminal device for a transhumeral amputation and elbow flexion? For prosthetic elbow lock? (Have to lock the elbow before the terminal device is opened)

Biscapular abduction & humeral flexion.
Shoulder depression & humeral abduction & extension

13

Prosthesis that is powered by a battery and uses myoelectric signals. It is controlled by various input methods

Externally powered prosthesis

14

Benefits of an externally powered prosthesis

Stronger grip force
Moderate or no harnessing
Minimal energy expenditure
Least body movement to operate
Moderate aesthetics

15

Limitations of an externally powered prosthesis

Heavier
More expensive
Limited sensory feedback
Extensive therapy training

16

A single prosthesis in which two or more technologies are combined
Less weight than fully powered system
More grip strength than a body powered system

hybrid prosthesis

17

Benefits of hybrid prosthesis

Simultaneous control of the elbow and terminal device
Reduced weight compared to all electric

18

Limitations of hybrid prosthesis

Less pinch with cable controlled TD
Difficult to lift battery powered TD

19

What are the limitations of traditional myoelectric control

Lack of control signals…usually just 2 electrodes
Rely on larger muscle groups for signal
Control muscles usually physiologically inappropriate

20

Post delivery rehab therapy includes:

Donning of prosthesis
Control of components
Functional training
Occupational performance

21

_____ training focuses on promoting readiness for the permanent prosthesis including promoting skin healing, conditioning, preventing contractures, controlling edema, and providing desensitization to the residual limb.
