Q

How are pelvic rotation deviations named?

What often accompanies these deviations?

A

named after the posterior half of the pelvis

accompanied by a compensatory counter rotation of the spine

22

adjust based on available hip flexion

improve foot clearance or allow foot propulsion

23
Q

just below the inferior angle of the scapula for pushers, lower if patient has improved trunk control

Hard-can be more supportive and cushioned

  • increased age
  • body weight
  • tobacco use
25

Cons:
-can’t be washed, increased skin temp., must be replaced every 6 months

26
Q

What are the pros and cons of air cushions for sitting in a wheelchair?

A

Pros:
-better weight distribution, lowest interface pressures if inflated properly

Cons:
-heavier, easily punctured, decreased stability, transfers are difficult

27
Q

What are the pros and cons of gel or fluid cushions for sitting in a wheelchair?

A

Pros:
-better weight distribution, minimizing shear forces during transfers, good choice for the active individual

Cons:
-heavy, promote increased skin temp. and moisture build up at the sitting surface, stability is decreased, difficulty of transfers is increased

28
Q

How often should wheelchair users perform pressure relief? How long should the relief be held for?

What methods help achieve this?

A

Every 15-30 minutes and held for 15-30 seconds

  • push-up maneuver
  • leaning to the side (hook)
  • leaning forward (must reach 45 degrees)
29
Q

What patients should use a powered wheelchair?

What patients should use a manual wheelchair?

A

Power:

  • pt. who is a marginal self-propeller or cannot self propel
  • limited endurance for community mobility
  • when manual use has the potential to lead to long term sequela

Manual:

  • lower cost
  • patients who want to maintain physical capacity
  • patients who want improved access and lower maintenance
30
Q

What are the two basic frames for a manual wheelchair?

A

Folding (smoother ride but heavier) and rigid (durable and lighter, also has adjustable seat to back angle)

31
Q

What is the camber of a manual wheelchair?

What is the optimal axle location for a manual wheelchair?

A

camber=angle of the wheels (outward angle improves efficiency and stability but decreases accessibility)

ideal axle location is just in line of the GH joint to have optimal “tipping”

32
Q

What are the 3 wheel systems for powered chairs and what are the advantages of each?

A

Rear Wheel: improves speed
Center wheel: improves turn radius
Front Wheel: improved terrain navigation

33
Q

What are the keys for propulsion in a wheelchair?

A
  • long symmetrical strokes
  • leaning forward enhances the propulsive forces
  • pushing forward on one side and pulling back on the other =sharp turns

users must be able to propel forward, backward, and over multiple terrains

34
Q

What are the keys for inclines/declines when in a wheelchair?

A

Inclines:

  • short forceful strokes
  • leaning forward enhances the propulsive forces
  • turning sideways allows user to rest

Declines:

  • slowly release pressure on the hand grips
  • leaning back enhances the breaking forces
  • turning sideways allows user to rest
35
Q

What are the keys for wheelies in a wheelchair?

A
  • balance point where front casters are off the ground and in equilibrium
  • user pushes forward on the rims to lean back
  • pushes back on the rims to lean forward

users need to be able to attain, maintain and move in the wheelie position

36
Q

What are the keys for ascent/descent of curbs in a wheelchair?

A

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

Descent: user pops a wheelie once the front casters are at the edge of the curb and uses leverage of the wheel against the curb to descend

37

50
Q

What are the indicators for a sport-specific wheelchair?

A

if individual participates in athletic event using a wheelchair

51
Q

What are the steps for prescribing a wheelchair?

A

1- determine need for wheelchair
