Week 6 Flashcards
- flat cushion
- ex: sitting on a table
- ischial tuberosities push through tissues of butt, bony prominences of butt press on hard surface, displaces tissue, cuts off blood supply, reduces oxidation and leads to necrosis
planar
t/f - it’s okay for people to sit in planar cushions for a short amount of time
true
- curved cushion
- having a well gives ischial tuberosities space to go
- takes away the pressure and allows a more even distibution of pressure
contoured cushion
regarding a cushion, ___ isn’t necessarily better.
softer
name a negative of not using a backrest.
upholstery is usually built with a sag/hammock in it, so person could collapse in it
where should the back height of a w/c be cut below in order for them to propel themselves with w/c?
inferior angle of scapula
why is cutting the back height of a w/c below the inferior angle of the scapula a good idea?
allows person to bring arms back and push wheels on w/c
as soon as you put a back rest on a w/c it moves depth ___.
shorter
name 3 types of patients who would need lateral supports.
- scoliosis
- lateral flexion
- anything that takes them out of midline position
what is the first part of the body that should be considered and prioritized regarding seating and positioning?
pelvis
if someone has a bend in their spine, where would the pads of the lateral support go?
3 points of control - high, low - concave, convex - where apex of curve is
why are there 3 points of control needed as lateral supports to fix a bend in the spine?
need counter action on other side (not just on one side)
- helps hold pt. up
- sometimes not possible on women due to breasts
- if you’re not stabilizing the hips and person loses pelvis position and collapses and slides down, chest strap
chest straps/harness
what do lap boards prevent arms from doing?
falling into internal rotation and flexion
describe optimal pelvic positioning support (seat belt) .
- better to be further forward - belt should be on femur, should be perpendicular to femur itself, just anterior to ASIS of pelvis
- prevents pelvis from sliding forward, allows pelvis to flex
