a. age
b. funding
c. living environment
d. individual needs and use

individual needs and use

2

A fixed asymmetry with malalignment that does not correct with minimal manual force will need what kind of intervention?
a. correct
b. accommodate

accommodate

3

What are the considerations for accommodation?

prevent worsening of symptoms
postural supports should match the fixed spinal curve
respect the ROM limitations
do not correct position to point of resistance or compensation at the pelvis

4

A flexible asymmetry that reverses with minimal manual force will need what kind of intervention?
a. accommodate
b. correct

correct

5

What is the primary goal of posture and positioning?

function

6

What needs to be considered with evaluation in short sitting?

what support does the pt need to maintain optimal posture?
is manual support by PT needed? and how much force is required, points of contact needed?

7

What needs to be considered with evaluation in supine?

ROM limitations
causes of "imbalanced" pelvis
spinal alignment/malalignment
quality of muscle tone
fixed verse flexible deviations

8

How should the pelvis be positioned in a wheelchair?

the hips as far back as possible

9

Positioning the hips as far back as possible will influence

puts axle position more forward - decrease rolling resistance - increase propulsion efficiency

10

What is important to consider for the front-end angle?
a. hamstring flexibility and tone
b. quad flexibility and tone
c. back flexibility
d. LE flexibility

hamstring flexibility and tone

11

If the footrest height is too low the patient will have

posterior pelvic tilt
anterior slide
feet not supported by foot rest

12

If the footrest height is too high the patient will have

increased ischial pressure
"splaying" of knees into abduction

13

The rear seat height should be (higher/lower) than the front

lower

14

An appropriate seat dump will
improve _ efficiency in elderly
improve propulsion biomechanics in _ subjects and _ the risk of injury
_ stabilizing muscle activity in SCI during reach tasks with tilt/reclined seat position

propulsion
SCI
decrease
decreased

15

If seat dump is too little, you will see
_ trunk balance
_ pelvic tilt for stability
_ slide

decreased
posterior
anterior

16

If seat dump is too much, you will see

decreased ability to transfer "tippy"
posterior pelvic tilt

17

The elbow should be flexed _ degrees with the palm at 12:00 handrim
a. 80-100 degrees
b. 90-100 degrees
c. 100-120 degrees
d. 110-120 degrees

100-120 degrees

18

If the seat height is too low, you will see
_ shoulder and wrist _
difficulty _

increased shoulder and wrist extension
difficulty transferring to other surfaces

19

If the seat height is too high, you will see

short push stroke
increased stroke frequency
fatigue

20

The goal with the backrest is to

optimize manual propulsion

21

Height for the backrest should be _ as possible and at least _ inch below the _

low
1 inch below the inferior angle of the scapula

22

if the patient is unable to balance in an upright back position

open the back angle

23

If the patients backrest is too reclined, you will see an

increased forward head
ceiling gazy
tippy

24

if the patients backrest is too upright, you will see
the trunk _ _
_ function without _ support

the trunk fall forward
unable to function without UE support

25

The lumbar support should support
a. the pelvis in a posterior tilt
b. the pelvis slightly anterior tilted
c. the pelvis in a neutral position
d. the pelvis in a natural position

the pelvis in a neutral position

26

seat tilt + posterior pelvic support =

stability

27

if the lumbar support is too high, you will see the patient

pushes upper back forward

28

if the lumbar support is too low, you will see the patient

push sacrum forward and encourage a posterior pelvic tilt

29

be cautious with _ for lumbar support

skin

30

in a manual wheelchair, after positioning the lumbar support, revisit _ position

axle

31

the axle should be as far (forward/backward) as possible

forward

32

how many inches should the front casters be off the floor in a balanced position for wheelies?
a. 2-4 inches
b. 3 inches
c. 1-2 inches
d. 1-3 inches

1-3 inches

33

If the headrest is too high the patient

probably needs to be pulled back into wheelchair

34

What 3 things need to be identified for the frontal view?

pelvis
lower extremities
trunk

35

What are 3 types of pelvic asymmetries?

obliquity
tilt: anterior, posterior
rotation

36

Pelvic asymmetries can be caused by

ROM limitations caused by HO, orthopedic restrictions, contractures
spasticity
muscle imbalance
ischial shaving for previous pressure sores

37

Trunk and neck asymmetries can be caused by

compensatory or pre-existing
righting responses

38

It is important to correlate asymmetries with mat evaluation (True/false)
