Q

What three factors contribute to considering powered wheeled mobility?

A
  1. Unable to propel due to UE limitations in strength, coordination, pain, ROM
  2. Home has adequate access for maneuvering
  3. Use will significantly improve ability to perform MRADLs

Q

What are the two functions of cushions?

A
  1. Pressure relief
  2. Postural control
22
Q

What are the 6 types of cushions?

A
  1. Foam
  2. Viscoelastic
  3. Gel
  4. Fluid filled
  5. Air
  6. Combination
23
Q

What are advantages of a foam cushion?

A

Inexpensive, lightweight, comes in range of densities, holds shape, provides even support, can be cut

24
Q

What are disadvantages of a foam cushion?

A

Wears out faster, loses shape, old foam can lead to sore development

25
Q

What are advantages of a gel cushion?

A

Excellent pressure distribution, comfortable, supplemental inserts to stabilize legs

26
Q

What are disadvantages of a gel cushion?

A

Heavy, leakage, less able to absorb impact, allow gel to push out to sides

27
Q

What are advantages of an air flotation cushion?

A

Lightweight, even pressure distribution, will not bottom out is properly inflated, modified to relieve pressure sores, waterproof

28
Q

What are disadvantages of an air flotation cushion?

A

Less stable, chance of puncture, high maintenance

29
Q

What degree of tilt defines a pressure relieving tilt?

A

> 30 degrees

30
Q

What effect does a tilt of 15 degrees or less have?

A

No advantage for pressure relief

31
Q

What is the effect of a 25 degree tilt?

A

Shear reduction

32
Q

What is the effect of a tilt up to 65 degrees?

A

Significant ischial pressure relief

33
Q

Does recline without tilt provide pressure relief?

A

No, may increase shear on back

34
Q

What are the three types of tires?

A
  1. Pneumatic
  2. No-flat inserts
  3. Solids
35
Q

What are advantages of pneumatic tires?

A

Lightest, shock absorbing, good traction, right amount of pressure can offer softer ride and provide tactile grip on wet surfaces

36
Q

What are limitations of pneumatic tires?

A

Requires regular maintenance

37
Q

How often should pneumatic tired be checked and inflated?

A

Checked weekly and inflated 1-2x per month

38
Q

What are the advantages of no-flat insert tires?

A

More grip and a softer ride than solid tired,

39
Q

What are limitations of a no-flat insert tire?

A

More rolling resistance than pneumatic or solid tires, heaviest, does not perform optimally outdoors, difficult to maintain

40
Q

What are the advantages of a solid tire?

A

Fully puncture proof, low maintenance, durable against chemicals and sharp objects, wear at a slow rate, higher tensile strength

41
Q

What are the limitations of a solid tire?

A

Less effective on rougher terrain, heavier than air tires, indoor use, rougher ride, increase rolling resistance

42
Q

What effect does the size of a castor have?

A

Larger castors leads to a smoother ride, but are less responsive to turns. Also can absorb shock

43
Q

What type of frame does not allow for elevating or removable leg rests, and what alternative is present?

A

Rigid frames, foot play may flip up to allow for easier transitions

44
Q

What are spoke wheels?

A

24-36 metal spokes, can be crossed or radial. Function to keep wheel aligned and provide a smooth ride

45
Q

What are mag wheels?

A

Synthetic material, made of 10 spokes. Less smooth ride but very durable

46
Q

What type of wheel yields a smoother ride?

A

Spoke wheels > mag wheels

47
Q

Why is the height of the wheelchair back important?

A

The height of a wheelchair back is directly correlated to how much support the client needs

48
Q

Describe alignment for pushing efficiency

A

Rear wheel axle should be in line with or slightly in front of the shoulder for most effective pushing

49
Q

What are the 6 seating principles?

A
  1. Stabilize proximal to promote improved distal mobility and function
  2. Achieve and maintain pelvic alignment
  3. Facilitate optimal postural alignment in all body segments, accommodating for impairments in ROM
  4. Limit abnormal movement and improve function
  5. Provide minimum support needed to achieve anticipated goals and outcomes
  6. Provide comfort
50
Q

What are the 6 key measurement considerations?

A
  1. Seat width
  2. Seat depth
  3. Seat height
  4. Footrest style and length
  5. Arm rest height
  6. Weight of individual and wheelchair
51
Q

What 6 elements need to be included in justification and establishing medical necessity?

A
  1. Describe specific functional limitation
  2. Detailed description of device
  3. Specific description of the effect of the device
  4. Description of evaluation process and how recommendation was determined
  5. Explanation why device is least costly solution
  6. Description of expertise of interdisciplinary team
