WC Propulsion and Development

Question 1

what direction should the wheelchair be when ascending a single curb?

Answer 1

forward

provides greater control of the chair and requires less effort by the caregiver

Question 2

steps for going up a curb in a wheelchair

Answer 2

face the curb
elevate the casters
move the chair forward until drive wheel contacts the curb
lower caster wheels on surface of curb
roll chair forward

Question 3

what direction should the wheelchair be when descending a single curb?

Answer 3

backwards

provides greatest control and requires less effort by the caregiver

Question 4

steps for going down a curb in a wheelchair

Answer 4

face backwards
rear wheels close to the edge of the curb
stand behind chair and control chair as it rolls backwards
use your thigh for added control
rear wheels come off first followed by the casters

Question 5

steps to ascend a slope in a wheelchair

Answer 5

push the chair forwards
elevate casters
may need to zigzag up or down the slope if it is steep

Question 6

when descending a slope forward you should

Answer 6

elevate casters

Question 7

when descending a slope backward in a wheelchair

Answer 7

all four wheels must be on the ground

Question 8

multiple steps in wheelchair–assisted

Answer 8

up backwards; down forward
strongest person holds push handles
additional helpers grasp the frame of the chair
tip chair back and roll drive wheels up or down over steps
patient in chair can assist in ascent pulling back on hand rim
at the top step roll the chair back until casters clear the step
most safely performed with two or three people

Question 9

what is the best shape for independent wheelchair propulsion?

Answer 9

semicircular

Question 10

during pre-ambulation you should

Answer 10

improve strength, power and endurance
increase or maintain ROM
enhance sensory integration
handling and moving affected extremity
develop postural stability
develop dynamic stability
improve trunk and pelvic control
deep functional balance responses

Question 11

pre-ambulation activities progress from

Answer 11

low CoG and large BoS to high CoG and small BoS

Question 12

maintaining a position precedes…

Answer 12

attaining a position

Question 13

stability precedes…

Answer 13

mobility; static to dynamic

Question 14

purpose/benefits of bridging/hooklying

Answer 14

allows weight bearing through the feet
precursor to assuming the kneeling position
BoS is reduced and CoM is raised
facilitates pelvic motions and strengthens low back and hip extensors

Question 15

when prone, there is a ____ BoS and a ___ CoM

Answer 15

wide BoS and low CoM

Question 16

prone on elbows

benefits and reasoning for

Answer 16

wide BoS and low CoG
improve UE and neck/head control
increaser extensor ROM ant hip extensor

Question 17

quadruped

purposes of

Answer 17

decreased BoS and raises CoM
weight bearing through hips and shoulder joints
improve upper trunk, lower trunk, LE, UE, neck/head control

Question 18

purpose/benefits of half-kneeling

Answer 18

improve head/neck upper trunk, lower trunk, and LE control
WB through hips in upright antigravity position
improve balance reaction
wide BoS, CoM rises

Question 19

purpose of kneeling

Answer 19

narrow BoS, CoM rises
improve head/neck, upper trunk, lower trunk and LE control
WB through hips in upright antigravity position
improve balance reaction

Question 20

what is the purpose of modified plantigrade?

Answer 20

wide BoS and high CoM
improve head/neck, upper trunk, lower trunk, UE and LE control
improve gravity reactions
functional posture
lead up for standing

Question 21

what is the purpose/benefits of standing?

Answer 21

narrow BoS and higher CoM
improve head/neck, upper trunk, lower trunk, and LE control
improve balance reactions
important for ADL skills
Lead-up for gait
