Question 17

most common muscle used for crutches

Answer 17

latissimus dorsi

Question 18

in order to propel the assistive device. help LE to move

Answer 18

scapular stabilizers= rotator cuff muscles

Question 19

more stable assistive devices

Answer 19

walkers

Question 20

three major categories of assistive devices

Answer 20

1. canes
2. crutches
3. walkers

Question 21

there are no restrictions on weight bearing; 100% of body weight can be borne on the LE .

Answer 21

full-weight bearing

Question 22

no weight is borne on the involved limb; foot/toes make no contact with floor/ground surface.

Answer 22

non-weight bearing

Question 23

only a portion of weight can be borne on the extremity; sometimes expressed as a percentage of body weight

Answer 23

partial weight bearing

Question 24

only the toes of the affected extremity contact the floor to improve balance (not to support the body weight)

Answer 24

toe-touch weight bearing/ or touch-down weight bearing

Question 25

weight bearing is limited by patient tolerance of weight borne on extremity

Answer 25

weight bearing as tolerated

Answer 26

1. walkers 2. bilateral crutches 3. single crutch 4. bilateral canes 5. quad canes 6. hemi cane 7. single cane

Question 27

first part of treatment in assistive devices

Answer 27

parallel bars

Question 28

best device from point a to point b

Answer 28

walkers
