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)
true
39
If correction requires excessive force, possible skin compromise and discomfort, should you accommodate or correct?
accommodate
40
What are two ways to accommodate and support?
custom orthoses
bracing
41
Postural supports (should/shouldnt) match the fixed spinal curve
should
42
Correct position to point of resistance or compensation at the pelvis (true/false)
false
43
with obliquity and scoliosis, should you accommodate or correct?
correct
44
What tone needs to be considered with front end angle?
hamstring tone
45
symmetry is the primary goal (true/false)
false
FUNCTION
46
