1 Wheel Chair components

Question 1

Seat Back: What is the optimal height?

Answer 1

• Just below the interior angle of the scapula for pushers
• lower if improved trunk control

Question 2

What are the stages of pressure injuries?

Answer 2

1 -

2- Partial thickness

3 - FUll thickness

4 - Deep tissue exposure

Question 3

What are pressure relief methods and when do patients perform relief?

Answer 3

Methods:

• Push up manuver
• Leaning to side (hook)
• Leaning forward (45 degrees)
• HOLD FOR 15-30 seconds

Perform every 15-30 minutes

Question 4

When would you use a power WC?

Answer 4

• Marginal self propell
• Limited endurance
• more adaptable

Question 5

What is the difference between folding and rigid WC?

Answer 5

Folding: Below seat cross bar

provide smoother ride, heavier

Rigid: lighter, higher functioning, durable

Question 6

What are cambers?

Answer 6

Angle of the wheel

Out improves efficiency and stability with turning but decrease access

Question 7

What makes the WC more tippy?

Answer 7

Axel location

further axel forward = tippy (loses propulsion)

optimal is lin line with the GH joint

Question 8

What are the keys to propulsion?

Answer 8

• Long symmetrical strokes
• Leaning forward enhances the propulsive force
• Pushing forward on side side and puling back on other - sharp turn

Question 9

What are keys for inclines?

Answer 9

• short/forceful strokes
• leaning forward for more propulsion

Question 10

What are keys to declines?

Answer 10

• Slowly release pressures on the hand grips
• Leaning back enhances the breaking forces
• turning sideways allows the user to rest

Question 11

What are keys to wheelies?

Answer 11

• Balance point: where front casters are off the ground
• User pushes forward on rims, leans back
• Pushes back on rims to lean forward

Question 12

Keys to curbs?

Answer 12

Ascent: user pops wheelie to get the front casters over the curb and uses forward leverage of the wheel

Descent: user pops wheelie once casters at edge
