Final - Power Mobility and Manual Mobility

Question 1

benefits of a power chair

Answer 1

get out in the community,

energy conservation, appropriate pressure sore release, increased independence

Question 2

limitations of a power chair

Answer 2

expensive, bulky/heavy, maintenance

Question 3

3 base choices

Answer 3

(where the big wheel is)
front wheel
midwheel
rear wheel

Question 4

drive wheel position affects

Answer 4

maneuverability - turning radius, obstacle climbing, tracking

Question 5

turning radius

Answer 5

RWD: back is a pivot, big turning radius
MWD: small turning radius, turns where you are
*easiest
FWD: little wheels turn behind you (have a tail)

Question 6

obstacle climbing

Answer 6

front wheel climbs over obstacles the easiest (powers through it)

Question 7

tracking

Answer 7

directional stability

RWD has the best = speed!

Question 8

seating systems

Answer 8

1. Stationary (standard)
2. Tilt - pressure relief (entire chair goes back)
3. Recline - just back part goes back, prevents hip contractures by stretching
4. Tilt/recline combo
5. Standing

Question 9

control - proportional

Answer 9

• Works like a gas pedal - the harder you push, the faster you go
• Offers more control (requires more coordination)

Question 10

control - non-proportional

Answer 10

• Turns on and off at a fixed speed (ie, slow, medium, fast)

* Offers less control (requires less coordination)

Question 11

control - momentary

Answer 11

• Moves only when rider delivers command and stops when released

Question 12

control - latched

Answer 12

• Continues to go until told to stop
(like a cruise control)
for someone with low endurance

Question 13

access devices

Answer 13

• Joystick
• Head array
• Breath control (sip and puff)
• Tongue-touch keypad
• Kill switch

Question 14

advantages/disadvantages of recline chairs

Answer 14

comfort, PROM of hips and knees, self catheterization, OH, edema

spasms, shearing

Question 15

advantages/disadvantages of tilt n space

Answer 15

decreased pressure sores and shear, edema, OH

can restrict the bladder, transport, price

Question 16

rigid vs folding frame

Answer 16

rigid - lighter, less maintenance, hard to transfer

folding - easy to transfer, heavier, use for short period of time

Question 17

wheel type

Answer 17

MAG wheels - heavy but sturdier
spoke - light, ***given to heavy wheelchair users
spinergy - the best (durable, light, good shock absorption)

Question 18

tire type

Answer 18

solid - heavy, no maintenance
pneumatic - light, better shock absorption, grab on surfaces
flat free - in between

Question 19

when are projections on handrails appropriate

Answer 19

someone with good hand function/dexterity

Question 20

seat slope/dump

Answer 20

the weaker the trunk, the more dump is necessary to provide support

Question 21

degree of camber average for everyday use

Answer 21

2-4 degrees
