Q

What are the muscles under the upper trunk group for NWB ambulation?

A

17
Q

What are the muscles under the lower trunk group for NWB ambulation?

A

trunk extensors and trunk flexors

18
Q

What are the muscles under the upper extremity group for NWB ambulation?

A

shoulder depressors, shoulder extensors and flexors, elbow extensors, finger flexors

19
Q

What are the muscles under the WB lower extremity group for WB ambulation?

A

hip abductors, hip extensors, knee flexors, knee extensors, ankle dorsiflexors, and plantar flexors

20
Q

There are no restrictions of weight-bearing and 100% of the BW can be borne on the LE.

A

Full weight-bearing (FWB)

21
Q

No weight is borne in the involved limb and foot/toes make no contact with the ground.

A

Non weight-bearing (NWB)

22
Q

Only a portion of the weight can be borne on the affected extremity and presented as percentage of the BW.

A

Partial weight-bearing (PWB)

23
Q

Only toes of the affected limb have contact with the ground

A

Toe-touch weight-bearing (TTWB)

24
Q

Weight-bearing is limited by the patient’s tolerance of weight borne on an extremity?

A

Weight-bearing as tolerated (WBAT)

25
Q

Categories of assistive devices ranked from highest to lowest in terms support magnitude.

A

Walkers
Bilateral crutches
Single crutch
Bilateral canes
Quad canes
Hemi cane
Single cane

26
Q

Used when maximal support and stability is required

A

Walkers

27
Q

Type of walkers include

A

Standard
Child
Reciprocal
Bariatric
Stair-climbing
Wheeled
Folding
One-handed

28
Q

What are the advantages of using walkers?

A

Wide BOS (provides anterior and bilateral lateral support)
Provides high level of stability
Provides sense of security (especially to the older population)

29
Q

What are the disadvantages of using walkers?

A

May be difficult to store and transport
Difficult to use on stairs
Difficult to perform normal gait pattern
Can be difficult to use in narrow spaces

30
Q

What are the advantages of using axillary crutches?

A

Enhances UE lateral stability
Allows UE to transfer body weight to the floor
Allows functional ambulation while maintaining WB restrictions status

31
Q

What are the disadvantages of using axillary crutches?

A

Less stable due to narrower BOS
Requires good standing balance
Provides less security to pts (especially to older population)
Adequate strength in the upper limbs is required

32
Q

What are the advantages of using forearm crutches?

A

Easy to store and transport
Eliminates the danger of injury
More functional on stairs and narrower spaces.

33
Q

What are the disadvantages of using forearm crutches?

A

Less stable than axillary crutches
Requires functional standing balance
Requires good UE strength for many gait patterns
Cuffs may irritate the pts wrists

34
Q

What are the advantages of using platform attachments?

A

Allows transfer of weight through forearm to assistive device

35
Q

What are the disadvantages of using platform attachments?

A

Pt loses the use of triceps to elevate and maintain the body during swing phase
Another person may be needed to apply/remove it.
Sometimes is difficult to attach
Less effective on stairs

36
Q

Platform attachment are aka

A

Forearm rests

37
Q

Platform attachments are used by pts who _____

A

are unable to bear weight on hands and wrists
have severe hand deformities
who have below elbow amputation
are unable to extend their elbows

38
Q

What are the advantages of using canes?

A

Easy to store and transport
Quickly adjustable

39
Q

What are the disadvantages of using canes?

A

Limited support due to small BOS
