Wheelchair Seating: Considerations For The Prop Sitter

Please note: exam questions are subject to change.

1. Which of the following are goals of positioning the prop sitter? To provide adequate proximal support for improved function To optimize function To prevent develop of or accommodate asymmetrical postures All of the above
2. What is a prop sitter? Independent sitter Requires hands on surface to maintain sitting Requires external supports to maintain sitting Cannot be seated
3. What is a common presentation in the prop sitter? Significant, non-reducible asymmetries High tone Independent sitting ability Independent standing ability
4. What are goals of accommodating asymmetries? Pressure distribution Comfort Function All of the above
5. To achieve maximum alignment, which of the following principles is required? Neutral position Force and counterforce Pressure distribution Leg length adaptation
6. Anderson is a 12-year-old young man with the diagnosis of cerebral palsy. He is seated in a tilt-in-space manual wheelchair with a molded seating system, however this is no longer accommodating his body shape as he has continued to make changes. He is a prop sitter, requiring significant postural support. He is dependent for transfers and uses a power wheelchair for mobility. Anderson has tight hip flexors. If his hips are extended beyond his available range, what destructive posture is likely to occur? Pelvic obliquity Pelvic rotation Posterior pelvic tilt Anterior pelvic tilt
7. Anderson shows rib cage distortion due to his spinal curvatures. Which curvature is leading to increased prominence of the right posterior rib cage? Kyphosis and rotation Lordosis Posterior pelvic tilt Anterior pelvic tilt
8. Andersons lateral scoliosis is reduced when sidelying. How does this translate into seating recommendations? Significant contact at the lateral pelvis and trunk will be required to reduce this asymmetry. He will require a lateral tilt. He will require lateral trunk supports. He will require anterior trunk support for counterforce.
9. What is an advantage of a molded seating system for Anderson? Cost Accommodating multiple and significant asymmetries of the pelvis, spine and rib cage Growth Temperature regulation
10. What two factors determined Anderson's seat to back angle? Hip flexor range and pelvic tilt The available adjustment on the manual wheelchair backcanes Hip flexor range and head balance The relation of the posterior point of the kyphosis and the posterior point of the pelvis
