chapter 13 seated mobility adl exam 3 Flashcards
Orthosis
device applied to body to stabilize of immobilize or assist with function
wheelchair
a type of orthosis.
wheelchair fit
must be fit and selected by pro. 68% of patient’s wheelchairs are not right for them. seat, back UE LE supports wrong position for their condition.
condition and wheelchair needs can change over time.
Besides measurement fits, what are some other concerns about selecting the right wheelchair?
- goals and desires
- frequency of use, longevity of use, durability needs environment
- cognitive sensory and cardiopulmonary abilities
- psychosocial concerns
- environmental
- financial
- care partner availability
- community and social resources
Manual wheelchair
lighter more prtable
Battery powered wheelchair
Heavier and harder for portability
Pushrim-activated power assist wheelchair
(PAPAW) - Smart Drive - can be much lighter.
Two main types of wheelchair seats
flexible “sling” or ridged. - both often have padding.
seat slope
“Dump” front of the seat is higher than the back. slope affects stability of pelvis.
Pressure map
pressure sensors placed on seat and back of wheelchair to guage comfort and when patients lack sensory cues.
wheelchair back support
standard 90 degree
Some (tilt in space) recline without changing the angle to the seat re relieve pressure.
Armrests
decrease weight on butt 5% for tetra 9% for para.
for menuverablility, may be omitted.
Front rigging
foot and calf supports
swing away foot and calf supports
facilitate transfers and allows manuverability.
elevating legrests
keep knee flexion over 90 degrees. Must have calf pad.
legrest and edema
tilt body back 30 degree or legs 30cm above heart can manage edema.
footrests for athletes
may be at slight inward angle for meneuverability.
wheelchair frame old
tubular steel (hospital wheelchairs)
New types of wheelchair frames
aluminum, titanium, airplane steel, carbon fiber
Fixed box frame
sturdier - top fold over seat. less energy to propel
cross brace frame
can fold up for storage better shock absorption - more energy to propel
frame of battery power wheelchair
ridged 85 to 300 lbs.
Pediatric wheelchair
often aluminum. expand
Integrated standing wheelchair
can move from sitting to standing while still supported by the chair.
Axel postion
Determines drive wheel position and stability and meneuverability.
axel postion back
more stable less meneuverable
axel position forward
less stable more meneuverable
Power chair axel postion
front, mid or rear drive
Rear wheel drive chairs
move more rapidly - less effective at inclines.
Front wheel drive chairs
good inclines and better at curbs.
mid wheel drive chairs
tight turning raidius. can get stuck over obstacles.
Drive wheels
push wheels 22,24,26 inch
spoked drive wheels
light weight, require meaintenance.
Mag wheels
light weight but not as light as spoked. six to 8 strutts. magnesium.
Camber
top of wheel angled in. Improves stability and agility.
Pushrims
handrims. rings outside drive wheel.
can have projections
can be ergonomic.
casters
small wheels for atability and direction change. turn and can extend BoS.
large casters
more stable but harder to propel
small casters
less stable but more menuverable
electric wheelchair 3 wheel
power-operated vehicles - more menuverable
electric wheelchair 4 wheel
less menuverable.
tires
pneumatic, foam filled solid
pneumatic tires
better shock absorption and better outside. harder to propel.
