Q

body powered prosthesis are called

24
Q

body powered prosthesis relies upon

Study These Flashcards
A

gross body movements captured thorugh a harness

25
benefits of body powered prosthesis are
moderate cost and weight durable environmentally resistant prioprioception through harness system
26
limitations of body powered prosthesis are
grip strength or pinch force restrictive & uncomfortable harness requires muscle power & excursion poor static & dynamic cosmesis
27
body movements needed for prosthetic control : transradial:
transradial - elbow flexion - elbow lock - terminal device needs: - scapular AB duction and humeral flexion
28
body movements needed for prosthetic control: transhumeral
elbow flexion - scapular ABduction / humeral flexion elbow lock: - shoulder depression and humeral: ABduction / extension
29
an externally powered prosthesis aka means
"electrically powered or "moyelectic"
30
an externally powered prosthesis is powered by
a battery and myoelectric signals - by various input methods
31
benefits of an externally powered prosthesis:
``` stronger grip forces moderate or no harnessing minimal energy expenditure least body movement to operate moderate aesthetics ```
32
limitations externally powered prosthesis:
heavier more expensive limited sensory feedback extensive therapy training
33
muscle groups for myoelectric control: transradial:
wrist flexors / extensors - FCR - FCU - ECRL / ECRB - EDC
34
muscle groups for myoelectric control: transhumeral :
biceps brachii triceps brachii deltoid
35
a myoelectric hand is always stronger than a
hook hand
36
hook will have less _____ but _____
pinch | is lighter
37
elbow has to be
body powered
38
hand can be
externally powered
39
why would we suggest an activity specific prosthesis:
FUNCTION IN ADLS
40
an activity specific proshesis is also
adaptive / recreational
41
activity specific is designed for
a specific activity | - an adaptation to an exisiting prosthesis
42
TMR means
targeted muscle reinnervation
43
a TMR is a
reassignment of nerves
44
some partial hand prosthesis options are:
1. silicone restoration 2. opposition prosthesis 3. mechanical systems 4. powered finger systems
45
success depends on
COMMUNICATION
46
what are the two phases of rehabilitation?
pre prosthetic | post prosthetic
47
parts of the preprosthetic phase:
presurgical | post surgical and in fitting process
48
post prosthetic phase is
after prosthetic delivery
49
primary goal of the preprosthetic phase is to
reinforce realistic expectations;
50
EMG steps:
develop two anatagnositic muscles with acceptable EMG output 2. develop EMG separation between the muscle sites 3. develop stamina in each muscle
51
things you have to teach with a new prosthetic aka interventiosn:
donning of prosthesis control of components functional training occupational performance
52
preprosthetic training focuses on :
promoting readiness for the permanent prosthesis
53
promoting readiness for the permanent prosthesis includes:
``` promote skin healing conditioning preventing contractures controlling edema providing desensitization to the residual limb ```
54
capability factors to getting a prosthestic:
physical psychosocial specific needs
55
performance factors to getting a prosthestic:
activity vocational future needs
