Q

What are the 5 weight bearing status descriptors?

A

FWB (full weight bearing)
-All weight put on limb
WBAT (weight bearing as tolerated)
-“Allowed” to put full weight, may not due to pain
PWB (partial weight bearing)
-Some weight put on limb, in form of %
TDWB/TTWB (touch down/ toe touch weight bearing)
-little or no weight, foot or toes more so for balance
NWB (non weight bearing)
-No weight put through limb

Why might you pick one frame over another?

A

Lighter frames = greater ease of use

Heavier = not as much function

89
Q

Caster wheels are small front wheels, and can be a solid rubber or pneumatic tire.

  • Pneumatic tires are often wider- travel easier on ________ surfaces.
  • “Rollerblade” wheels- ultra light or ______ wheelchairs.
A
  • uneven

- sports

90
Q

Drive wheels and tires can be solid rubber or pneumatic tires.
-Inner rims are for _________ tires while the outer rims are for _________.

A
  • mounting

- propelling

91
Q

Additional Attachments:

  • Extensions for brakes
  • Seat belts
  • ____ _________: lateral at hips or knees or medial at knees to facilitate LE alignment
  • Seat back positioners: lateral trunk support
  • ___-_____ device: posterior extension attached to horizontal supports to prevent tipping backwards
  • ____ _______ device: mechanical brake that allows forward progression but automatically brakes if rolling backwards
A
  • seat positioners
  • anti-tipping
  • hill holder
92
Q

What are the variations of wheelchairs?

A
  • Reclining back
  • Tilt in space
  • One-arm drive wheelchair
  • Hemiplegic chair
  • AMP chair
93
Q

When are One-Arm Drive Wheelchairs used and how are they different?

A
  • Used if the pt has one functional UE
  • 2 hand tims attached to the same wheel, larger rim controls far drive wheel, smaller rim controls near drive wheel. Pushing both rims simultaneously moves wheelchair forawrd/backward.
94
Q

A Hemiplegic chair is low to the ground, why?

A

Allows for propulsion with noninvolved UE and LE.

95
Q

AMP Chair:

  • A LE amputation moves the pt’s COM ___________ when seated.
  • Wheelchair has increased chance to tip posteriorly.
  • Drive wheels set behind the vertical back support.
  • Moves BOS further to the rear.
A

posteriorly

96
Q

When are Recliner chairs used?

A
  • pt can’t maintain upright position

- help distribute weight

97
Q

A Bariatric Chair involved the axis moving _________ so the person is less likely to tip forward.

A

anterior

98
Q

Basic Concepts for Wheelchair Fitting:

  1. )Stabilize ___________ to promote improved distal mobility and function
  2. ) Achieve and maintain _________ alignment
  3. ) Facilitate optimal __________ alignment in all body segments, accommodating for impairments in range of motion
  4. ) Limit abnormal movement and improve ________
  5. ) Provide the __________ support necessary to achieve anticipated goals and expected outcomes
A
  • proximally
  • pelvic
  • postural
  • function
  • minimum
99
Q

What are some considerations for wheelchair selection?

A
  • Prognosis (temp or permanent)
  • Functional ability (user and/or helper)
  • Environmental constraints
  • Safety
  • Expense
  • Low tech vs high tech
100
Q

What are the 4 principles of positioning?

A
  • Patient comfort
  • Stability and alignment
  • Pressure sore prevention
  • Respect precautions/contraindications
101
Q

What measurements are often taken during measuring for a wheelchair?

A

-seat to floor height
-seat depth
-seat width
-back fack heigh
-armrest height
seat-to-footplate length

102
Q

Seat Width

  • Measure?
  • +/-
  • Too Little?
  • Too Much?
A
  • Measure = widest point while seated
  • +/- = +.5-1” to both sides
  • Too Little = Pressure on sides of greater trochanters
  • Too Much = Hard to reach wheels
103
Q

Seat Depth

  • Measure?
  • +/-
  • Too Little?
  • Too Much?
A
  • Measure = Back of support surface to popliteal crease
  • +/- = 2-3”
  • Too Little = Feel like sliding off = pressure on ischial tub
  • Too Much = Popliteal crease pressure = slide forward and slouch
104
Q

Seat to Floor Height

  • Measure?
  • +/-
  • Too Little?
  • Too Much?
A
  • Measure = Floor to top of seat cushion
  • +/- = +1-2” to clear foot plates
  • Too Little = Knees higher than hips; pressure on ischial tuberosity
  • Too Much = Footrest too long: sacral sit and slouch, Seat too high: cant sit close to table
105
Q

Back Height

  • Measure?
  • +/-
  • Too Little?
  • Too Much?
A
  • Measure =
  • +/- =
  • Too Little =
  • Too Much =
106
Q

Armrest Height

  • Measure?
  • +/-
  • Too Little?
  • Too Much?
A
  • Measure =
  • +/- =
  • Too Little =
  • Too Much =
