What % if UE amps are from trauma
Males? |
- 40%
- 4:1 |
|
|
Goals of early preprosthetic care
|
1. promote limb shrinkage and shaping
2. desensitize 3. maintain ROM 4. Increase strength 5. Max ADL's 6. if myoeletric - determine muscle site 7. educate and make goals |
|
|
How to limb shrink and shape (5)
|
- figure 8
- distal to prox - NEVER CIRCULAR - reapply every 3-4 hours - only take off to bathe |
|
|
techniques to desensitize (5)
|
- massage
- tapping - vibration - pressure - texture exposure |
|
|
What is phantom limb sensation
|
- ability to perceive cortical images of the lost limb
- *almost every acquired amp - does not need to be treated |
|
|
What is phantom limb pain
occurs at: |
- can begin immediate post amp but should go away
- if interferes with life for more than 6 weeks, must be aggressively treated *occurs at somatosensory cortex |
|
|
What is residual limb pain
3 causes |
- pain that doesnt descend into phantom
-neuroma - poorly fitting prosthesis - physical changes |
|
|
4 top developmental signs that a child is ready for a prosthetic
|
1. sits without support
2. explores residual limb while supine 3. tries to hold object in elbow fold or agianst body 4. responds to verbal instructions |
|
|
Most frequent amp recommended
- most common hook |
- Voluntary opening hook
- Hosmer-Dorrance |
|
|
How does voluntary opening work
|
- force prehension determined by rubber bands
- each rubber band produces 1 pound of prehensile force |
|
|
What are wrist units
3 positions |
- connect terminal device to prosthetic forearm
- neutral, 25 deg, 50 deg flexion |
|
|
TRaining for prosthetic time
|
- 15-30 min 3x/day
|
|
|
How to open device
- below elbow amp - above elbow amp |
- scap abduction and shoulder flexion
- shoulder flexion |
|
|
how to lock the elbow
|
- down, back , out
- shoulder depression, humeral extension. shoulder abduction |
|
|
Myoprosthetic
- what does size of signal depend on |
- number of motor units recruited and their firing rates
- then amplified |
|
|
Best fit
|
- below elbow amp
|
|
|
Advantages of MYO
|
- requires less body motion
- more normal looking - no harness - ease in all planes |
|
|
Disadvantages of MYO
|
- cost
- fragile - weight - noise - socket heat - no in wet/dirty places |
|
|
advantages of conventional prostheisis
|
- easy to maintain
- cheap - reliable |
|
|
What is a hyprid system
|
- combines body powered and externally powered components
|
|
|
Advantage of hybrid
|
- lighter
- smaller harness - decreased cost |
|
|
Disadvantage of prosthetic wear
|
- impede function
- reduce sensation - hard to skin match |
