WC Measurements Flashcards
How to measure seat depth?
Posterior buttock to popliteal space (-2 inches)
How to measure hip width?
Width across lap of patient (widest part) (+2 inches)
How to measure chest width?
Distance between R and L axila
How to measure shoulder width?
Widest part across both shoulders
How to measure seat to elbow?
From bottom of patient in sitting, elbow 90 degrees of flexion
How to measure seat to axilla?
Bottom of patient to axilla
How to measure seat to shoulder?
Bottom of patient to acromion process
How to measure seat to pt head?
Bottom of patient to patients head
How to measure popliteal fossa to heel?
Measure length of lower leg
How to get a proper fitting
Start at the pelvis and use the3 point method. The 3 point method is using the 3 points of trunk control
Ex: The pt leans R. So we will put 2 points of support to the R and 1point on the L
How do we test for Posterior pelvic tilt in a WC?
Roll forward and backward.
-Lordotic curve: back extended and LE’s ABD
If they have a flexible posterior pelvic tilt what do we do and use a WC?
FIX IT
-Pommel: an attachment used to separate the knee and lumbar support.
-Anterior/posterior trunk supports
What do we do if they have a fixed Posterior pelvic tilt and use a WC?
ACCOMODATE.
-Open seat to back angle to match pelvic angle
-Decrease pressure tilt in space.
-Accommodate pelvis
How do we test for windswept legs?
Hip ABD and ER, genu virus at knee and other knee/hip are ADD and IR- genu vagus
What do we do if they have flexible windswept legs and use a WC?
Treat with proper width of the seat. Not too high and contoured seat pommel. Also add lateral thigh support and foot straps.
What do we do if they have fixed windswept legs and use a WC?
Accomodate
-Foot plate that is fit to both feet.
-Contact of back and seat with custom cushion to hold position.
-Measure true point seat width
How do we test for kyphosis?
Excessively posterior convex curve which is common in the thoracic. “Round back”
What do we do if they have flexible kyphosis and use a WC?
Anterior chest/shoulder support to the mid thoracic- support tilt in space
What do we do if they have fixed kyphosis and use a WC?
Open back seating, tilt frame, and a custom molded back
How do we know if a pt has scoliosis?
Their back will be shaped like an S or a C
How do we treat a flexible scoliosis on a WC?
Lateral trunk support
-3 point pad system…. 1 pad apex of convex, and 2 pads on top/bottom on concave aspect, with anterior trunk support
How do we accomodate a fixed scoliosis with WC?
Custom back
Lateral tilt support under seat to fix head position
