UE and Special Populations Flashcards
What motions are lost during B/E amputations?
pronation and supination
What are bony landmarks and why are they important?
C7 - harness ring below to not put patient into neck flexion
Clavicle - site of breakdown
Acromion - to measure length of residuum
Scapula - need good mobility to function prosthesis
How does a patient open terminal device in a B/E manual prosthetic? Close the device?
shoulder flexion and protract scapula
- puts tension on the cable
shoulder extension to relax cable tension
How does an A/E patient lock their manual device elbow to operate the terminal device?
Elbow lock through depression of shoulder with humeral abduction and extension and then operate terminal device
What motion closes the terminal device in a myoelectric system?
flexion closes the device
- just like wrist flexors close the hand
What is the most important thing for bilateral transfemoral amputations?
reliable stance phase
- swing phase is important but reliable stance is the most important
What kind of characteristics will bilateral transfemoral gait have?
- wide based with decreased speed
- typically use some AD
- very taxing
- community barriers
What are rehab goals for pediatric amputees?
- ROM > strength
- AD use
- education on skin care, device function, and donning/doffing
What compensates for lack of PF in the amputated leg?
- overactive hip musculature
- ↑ energy absorption and generation at the hip of the amputated leg
During a squat, eccentric _________ power is increased in sound limb, but eccentric _______ power was greater in amputated leg. Why?
hamstring, quad
- Eccentric hamstrings to decelerate limb and eccentric quad to control lowering
Why is hip extension important in prosthetic running?
- Need adequate hip extension ROM and strength to pull through stance phase
- causes speed and power
- loads the forefoot of the prosthesis - where you will get spring back
- increase contralateral stride length
