what are the pros to a folding frame
shock absorption
smoother ride
more flexible
easy to transfer
what are the cons to a folding frame
heavier
greater maintenance
what are the pros to a rigid frame?
less maintenance lighter stronger easy to propel fewer movable parts
what are the cons to a rigid frame?
decreased shock absorption
difficult to get in car
uncomfortable ride
what type of frame are sports chairs?
active duty light weight
name the material of frames from heaviest to lightest.
steel, aluminum, titanium
what is the tradeoff for a high back?
less mobility
for a more active individual, should you have a high or low back?
low back
what type of support does back upholstery give? does it interfere with the folding of the chair?
moderate support
no
what is one negative side and one positive side to wrap around armrests?
reduces the width of the chair
easier manuevarability
what are the positives to the full length armrest?
larger surface for pushup transfers
space for upper extremity support surface
who would benefit from height adjustable armrests?
kids
useful for people who need more or less support throughout the day
features of a rigid leg rest.
decreases propulsion
gets in the way when performing a transfer
features of a folding frame leg rest.
removable
you can specify the angle
what is the negative side of placing the axle in the front.
it shifts the COM posterior and can cause tipping
difference between spokes and mags.
spokes: increased shock absorption, lighter, more maintenance
mags: less shock absorption, heavier, less maintenance
difference between solid and pneumatic tires.
solid tires: decreased traction, decreased shock abosrption, decreased maintenance
pneumatic tires: increased traction, increased shock absorption, more risk for flat tires
difference between large and small castors.
large castors: larger turning radius, more effort to start moving, smoother ride
small castors: smaller turning radius, less effort to start moving, harder to maneuver over obstacles
someone with a C5 injury will utilize what type of brake?
pull brake
which patients get a head/neck support? what does it allow for?
patients with a fair, poor, or absent head control
increased resp, swallowing/feeding, increased safety, promotes neutral cervical spine, visual interaction
what are the negatives to a head/neck support?
skin problems
what are lateral trunk supports indicated for?
weak and spastic muscles
what do lateral trunk supports allow for?
increased postural alignment, pelvic alignment, controls lateral trunk flexion, respiration, swallowing, increases weight of chair and interferes with self propulsion
what may interfere with transfers if fixed?
lateral hip guides
