Q

considerations for air cushion

A
  • high protection for skin
  • comes in low, mid, high grade
  • high maintenance, can pop
  • more disruptive to posture

Q

considerations of hybrid cushions

A
  • combo of air or gel and foam
  • offers additional stability over posterior thighs
  • good option for patient who need air but struggle with posture - but lose full coverage/protection

17
Q

Which armrests require hand and finger use?

A

flip-back

18
Q

considerations of rigid footrests

A
  • less maintenance
  • extra thing to maneuver feet around during transfers
19
Q

considerations of swing-away footrests

A
  • ideal for gait trials
  • need adequate hand and wrist function to operate
20
Q

considerations for rubber wheels

A
  • havier option
  • way less maintenance
21
Q

considerations of air wheels

A
  • lighter option
  • smoother ride
  • more maintenance, can pop
22
Q

considerations of push-rims wheels

A
  • allow for easier propulsion, can build up to compensate for weaker grip
  • makes chair wider - more difficult to negotiate tight spaces
23
Q

different considerations for small and large casters

A

small casters are more lightweight

larger casters are beneficial when frequently negotiation outdoors/rough terrain

24
Q

Which drive has the largest turn radius?

A

rear wheel drive

25
Q

Which drive is the fastest?

A

rear wheel drive

26
Q

Which drive is the most maneuverable for indoors?

A

mid wheel drive

27
Q

Which drive is best for navigating tight corners?

A

front wheel drive

28
Q

Which drive is best for rough terrain?

A

front wheel drive

29
Q

considerations of front wheel drive

A
  • larger turning raidus than mid wheel but excellent at navigating tight corners
  • helpful with negotiating rough terrain
30
Q

considerations of rear wheel drive

A

largest 360 degree circumference and turning radius
- fastest chair
- good for folks going longer distances like traveling across college campus

31
Q

considerations of mid wheel drive

A
  • most maneuverable, excellent indoor chairs
  • fair maneuverability over outdoor surfaces
32
Q

T/F: Rear wheel drive is good for small apartment or dorm room

A

false - front or mid would be better

33
Q

Which drive is best for steep inclines and declines? Why?

A

mid wheel drive
- has front and back casters which help chair from tipping

34
Q

What is needed for a standard joystick?

A

need grasp (thumb or finger) and good control of UE

35
Q

What is needed for football post joystick?

A
  • the ability to lift hand on and off
  • C5/C6 may struggle if they cant lift their hand off
36
Q

pros and cons of chin control

A

pros - can still talk while negotiating chair vs tongue control

cons - TMJ issues

37
Q

What is needed for sip and puff control?

A

stable pulmonary status

38
Q

general wheelchair considerations for high cervical (C1-C4)

A
  • PWC
  • head array, chin, tongue, or sip and puff controls
  • portable respiratory may be attached
39
Q

general wheelchair considerations for C5

A
  • can use manual chair with propulsion aids, but likely need PWC for distance and energy conservation
  • sip and puff, chin, tongue, or football post controls
40
Q

general wheelchair considerations for C6

A
  • PWC for longer distances
  • can start to consider manual chair w/ friction surface hand rims
  • should progress to independent on smooth surfaces
41
Q

general wheelchair considerations for C7

A

manual chair with friction surface hand rims but increased propulsion ability

42
Q

general wheelchair considerations for C8

A

manual chair with standard hand rims
