Wheelchair Seating Flashcards
Obliquity
One side is lower than the other
Common with UMN issues with spasticity or high tone
Can tell via the ischial tuberosity
Rotation
One side is more forward than the other
Tilt
Top of pelvis forward or backward
Anterior: Is common with Spina Bifida for stability.
Windswept
All of these: Rotation, Tilt, Oblliquity
When assessing someone for posture, look at the ____ and ____ to determine how to properly adjust someone.
Pelvis and Ribs
Three points of contact to straighten someone out:
Hip, Rib, and Hip.
- Should leave about an inch below the axilla. (Two finger widths)
- Use large enough pads to distribute pressure evenly.
- If there is a lot of pressure at one point consider moving the pad.
- Applying a pad tighter to the body can sometimes result in less force which is good!
In order to correct scoliosis in this example you would
Apply a pad on the middle left ribs and one the on the lower right ribs.
Types of equipment options for wheelchair positioning
- Deep contour backrest
- Custom molded backs
- Tilt/Recline
Recline vs Tilt Chair
Recline opens up the hip angle. (Almost no one rotates from recline alone).
Tilt: Whole seat tilts back, takes pressure off backside.
Changing someones trunk posture for scoliosis a vest is used to…
Press on the bony process of the sternum
Wheelchair Propulsion Techniques
Fit and Support Considerations
Seat Width: Widest point to widest point; Make sure the tape is taught to get an accurate measurement.
Seath Length: Go as far back as the persons butt can go up to the back of the knee
Back Height: Height of the axilla
Back Width: Chest Width to best support the fit of the back
Shoulder Width: Helps in determining wheel angle
Hip Width Measurement - APTA Exam Question
Take linear hip measurement and then add 2 inches for a coat
In reality would not work this way.
Back Height Measurement - APTA Exam Question
Shoulder should be able to get to 90 degrees. Frees up the scapula; applies more toward an athlete in a wheelchair.
The length from the axilla to the legs determines…
how fast someone can turn. The larger the distance the slower the turn. Figure skaters physics apply here with moment arms.
The most perscibed wheelchair is ____
K0001-K0003
This would be recovering from an injury; shorter term.
Titanium vs Aluminum for a wheelchair, what to choose?
Titanium and Aluminum weigh the same, Titanium allows for less load transmission making it more comfortable; kinda like springs on a car.
____ and lower does not require extra specialized people, such as an assistive technology professional with training to do the measurement
K0004
If you qualify for a wheelchair you also qualify for…
a seat and back!!!
Specificaly ask for general use back and cushion which will allow for increased comfort and more anatomical support.
Target pressure based on capillary refill is
32 mmHg and less
More than this leads to occlusion and ischemia
Off loading after 30 minutes of sitting on a wheelchair should be how long?
30-60 Seconds
Can do shifting side to side or wheelchair pushups.
No more than ____ hours at a time should be spent in the wheelchair without a rest out of the chair.
2
A ____ should be used for patients who do slideboard transfers.
push to lock
Soft foam, gel and air work by
increase the surface area by wrapping around and decreases the force
