User Measurement
- Pelvic Width
Corresponding Equipment Measurement - Seat Width |
| |
A measurement
of the maximum width of the hips at the level of the greater trochanter
of the widest point.
- Wheel access
- Pelvic position
and stability
- Growth
|
| B |
User Measurement
- Sitting Depth (Upper Leg Length)
Corresponding Equipment Measurement - Seat Depth |
| |
A measurement
from the most posterior portion of the buttocks, or from the back
plane to the posterior surface of the medical hamstring tendon at
the back of knee. A right and left measurement should be taken into
account for any discrepancy.
- Pressure
distribution
- Pelvic position
and stability
- Overall frame
length / maneuverability
|
| C |
User Measurement
- Lower Leg Length
Corresponding Equipment Measurement - Footrest / Legrest Length
(Note: Legrest length is the measurement minus the cushion depression) |
| |
The distance
from under the knee (popliteal fossa) to the bottom of the heel, or
the most interior weight bearing surface of the foot if the ankle
is fixed in planar or dorsi flexion. Consider any additional length
due to shoe or orthotics that would normally be worn by the individual.
It is important to measure the right and left lower leg in the same
situation to account for any leg length discrepancies.
- Pressure
distribution
- Pelvic position
and stability

| D/G |
User Measurement
- Inferior Angle of the Scapula (each side)
Corresponding Equipment Measurement - Active Back Height
(Note: Back height is the functional back measurement plus the cushion
depression) |
| |
A measurement
from the seat rail plane to the inferior angle of the scapula. Active
back height should be positioned at one inch above or one inch below
the inferior angle of the scapula."
Possible pressure point
- Thoracic
and lumbar support and stability
- Scapula stability
and/or mobility
|
| E |
User Measurement
- Shoulder Height
Corresponding Equipment Measurement - Back Height / Grommet
Height
(Note: Back height or grommet height is the measurement plus the cushion
depression)
|
|
The measurement
from the seat rail plane to the top of the shoulder.
- Scapular
stability and mobility
- Thoracic
and lumbar support and stability
- Head control
|
| F |
User Measurement
- Sitting Height
Corresponding Equipment Measurement - Head Support Height
(Note: The head support height is equal to the measurement plus the
cushion depression) |
|
- Reference
point for the amount of adjustment needed in the head support
hardware
|
| H |
User Measurement
- Thoracic Depth
Corresponding Equipment Measurement - Thoracic Support Size or Positioning
Fore/Aft
(Note: When considering the thoracic support size it is important
to take into consideration the depth of the back support surface and
its placement relative to the back uprights) |
| |
The depth of
the thoracic cavity is taken at the point on the thorax determined
to be appropriate for lateral support. |
| I
|
User Measurement
- Pre-Ischial Crease
Corresponding Equipment Measurement - Ramp Position (anti-thrust seat) |
| |
A measurement
from the most posterior portion of the buttocks, or from the posterior
surface of the medical hamstring tendon at the back of the knee. A
right and left measurement should be taken into account for any discrepancy
or asymmetry. |
| JR/JL |
User Measurement
- Elbow Height (each side)
Corresponding Equipment Measurement - Armrest Height
(Note: Armrest height is equal to the measurement plus the cushion
depression) |
| |
he measurement
from the seat rail plane to the inferior portion of the elbow when
the upper extremity is positioned in 90 degrees of elbow flexion
and slight shoulder flexion and abdution. Consider taking a right
and left measurement given a pelvic obliquity, scoliosis, right
or left tone asymmetries.
- Thoracic
stabilisation
- Head control
- Functional
work surface
|
| K |
User Measurement
- Superior Angle of Anterior Pelvic Tilt
Corresponding Equipment Measurement - Position of Bi-Angular Back
Fold Point
|
| |
A measurement
from the seat rail plane to the position of the top of the anterior
tilt. The bi-angular back fold should be positioned approximately
one inch higher than this line (usually 1" - 2" below waistline) |
| L |
User Measurement
- Foot Length and Width
Corresponding Equipment Measurement - Footplate / Shoe Holder Length
and Width
|
| |
The user's foot
length and width measurement should be taken to include the shoes
and any ankle or foot orthotics devices normally worn by the individual.
- Foot support
and position
- Foot protection
- Foot clearance
