SCI W/C Considerations Flashcards
How is seat to back angle and tilt angle determined?
The activity level and level of athleticism of your patient
What is the back angle called?
Squeeze
What is the tilt angle called?
Dump
More squeeze and dump leads to…
A more efficient arm stroke for wheeling
What is arm rest height?
Measurement from the side of buttocks to the bottom of the bent elbow (elbow parallel to floor)
Considerations for measuring armrest height
Add one inch to the measurement and adjust for cushion height
2 types of WC frames
Folding
Rigid
Advantage of folding frame
Easy storage
Flexes to enable all four wheels to stay on the ground when riding on uneven surfaces
Removable foot rests allow for standing pivot transfer or feet on floor during transfer
Disadvantage of folding frame
Less efficient due to moving joints
Sling seating system
Heavy (>36 lbs)
Bulky with many moving, adjustable, and removable components
Lateral stability can decrease as the chair flexes or starts to fold
Seat to back angle usually not adjustable
Advantage of rigid frame
Fewer components thus more strength for a given weight
Usually lighter weight than a similarly equipped folding chair
Fewer removable parts
Seat-to-back angle adjustable
Easier loading into car
Disadvantage of rigid frame
May feel bumpier on uneven surfaces (more likely to tip over)
Can trigger clonus/spasticity
Does not fold into a small package for storage
Pt needs to be independent for transfer without feet on ground
What does the axle plate do?
Permits adjustment of wheelbase length and seat height
Increase in stability leads to
Decrease in mobility
Increase in the base of the WC leads to
Increase in stability
Decrease in base of the WC leads to
WC easier to tip (easier to wheelie)
