Q

Define TTWB (toe-touch or touch down weight bearing)

A
  • foot contacts ground for balance only or up to 20% of body weight
22
Q

Define PWB (partial weight bearing)

A
  • usually 20% to 50% of body weight
23
Q

Define WBAT (weight bearing as tolerated)

A
  • limited only by patient tolerance (> 50%)
24
Q

Define FWB (full weight bearing)

A
  • no restriction (100%)
25
Q

Ways to monitor weight bearing status

A
  • bathroom scale
  • limb load monitors
  • clinician foot/hand (not recommended as it puts the pt & therapist at risk)
26
Q

List the assistive devices from most stable to most mobile

A
  • parallel bars
  • walker
  • bilateral axillary crutches
  • bilateral forearm crutches
  • bilateral canes
  • hemi walker
  • quad cane
  • single point cane
  • no device
27
Q

Fitting the patient with an assistive device

A
  • goal is to have a 20-30 degree bend in the elbow
  • device should be on the floor (back legs of walker even with pt’s mid foot; crutches 2 inches lateral & 4-6 inches anterior to the toes & 3 fingers below the axilla)
28
Q

Advantages of parallel bars

A
  • maximal stability, support, & safety to build skills
  • great place to initiate gait training, balance training, & to evaluate fit of other AD’s
  • allows for multiple staff to assist
  • guarding within bars provides greater protection against falls
29
Q

Disadvantages of parallel bars

A
  • severely limits mobility
  • bars must be wide enough for patient to ambulate through
  • not practical
30
Q

Advantages of walkers

A
  • used when maximal stability, support, & mobility are required
  • rolling walker = faster continuous gait pattern when compared to a standard walker
31
Q

Disadvantages of walkers

A
  • facilitates flexion of the trunk
  • patient may try to pull & alter sit to stand
  • patient loses arm swing
32
Q

Advantages of trough/platform attachments

A
  • used for patients who are unable to bear weight through their wrists & hands or have severe deformities of the UE
  • may help those with UE amputation or are unable to extend elbow
  • provides additional stability
33
Q

Disadvantages of trough/platform attachments

A
  • unable to use triceps
  • may require additional assist
  • not as effective on stairs
  • difficulty to manage in home environment or around obstacles
34
Q

Advantages of canes

A
  • used to compensate for impaired balance or to improve stability/confidence
  • more functional on stairs & in narrow confined areas/community areas
  • easily transported
35
Q

Disadvantages of canes

A
  • very limited base of support
  • not ideal for a 3 point gait pattern or anyone with a weight bearing limitation due to lack of stability
36
Q

Guarding during gait

A
  • typically behind & slightly tot he weaker side
  • control points at the pelvic area & shoulder girdle
  • one hand is typically grasping the gait belt & the other hand hovers at the contralateral shoulder
  • anticipate the patient’s actions & responses to the environment & prevent or control any major losses of balance
37
Q

Describe four point gait pattern

A
  • requires use of bilateral ambulation aids
  • very slow & stable pattern
  • low energy demand
  • sequence = AD, opposite LE, AD, opposite LE
38
Q

Describe 3 point gait pattern

A
  • requires bilateral ambulation aides or a walker, but cannot be performed with bilateral canes
  • stable gait pattern, requires less strength & stability, but slow
  • sequence for NWB & PWB = AD(s), PWB extremity, WBAT or FWB extremity
39
Q

Describe two point gait pattern

A
  • used with two or one assistive device
  • stable gait pattern & faster than four point gait
  • low energy, similar to normal gait
  • requires more coordination
  • sequence = AD & one LE, other LE & device follow
40
Q

Describe step to or swing to gait pattern

A
  • the trail LE will only advance as far as the lead LE
  • more stable
  • good for cognitive stage of learning
  • slower speed, more taxing
41
Q

Describe step through or swing through gait pattern

A
  • the trail LE will advance past the lead LE
  • simulates more typical gait pattern
  • increased speed & improved energy conservation
  • progression of gait
  • decreased stability, requires increased control/balance
42
Q

Describe stairs with crutches

A
  • guard posterior to the patient as they ascend/climb the steps
  • guard anterior to the patient as they descend
  • crutches go first in descending the stairs and go last in climbing the stairs
43
Q

Describe stairs for different assistive devices

A

Quad cane: not advised to have cane and both feet on the same step
Single point cane: stays back with affected leg
Walker: can place on flat platform and walk into walker, go up the stairs backwards, fold walker and place opposite of railing, or turn the walker and place opposite of the railing

44
Q

Describe stairs with a cane

A

Sequence to ascend: intact LE, involved & cane at same time follow
Sequence to descend: cane first, involved LE follows, then intact LE

45
Q

ow many stairs is considered a full flight of stairs

A
  • 12 to 13 steps
46
Q

Describe curbs with a rolling walker

A
  • have patient place rolling walker on curb first if curb is < 4 inches
  • have patient turn around & use a retro technique if curb is > 6 inches
47
Q

How to go through a door that opens toward you

A
  • stand close to the door, turned slightly toward the hinges
  • pull door open, then push it fully open with same hand
  • block door with crutch tip if needed
  • walk through doorway
48
Q

How to go through a door that opens away from you

A
  • stand close to the door, facing door handle
  • push door wide open
  • block with crutch tip if needed
  • walk through
49
Q

Prevention of falling with crutches by addressing

A
  • person: balance, strength, appropriate device
  • task: effective gait training
  • environment: good lighting, removing obstacles
50
Q

How to decrease risk of injury in a fall with crutches

A
  • dropping crutches out to the side
  • slightly flexing elbows of extended arms
  • turning head to the side
51
Q

How to get up after a fall with crutches

A
  • gather crutches
  • move into kneeling with both crutches on one side
  • move into half-kneeling on stronger LE
  • move into full standing & place a crutch on each side
