Wheelchair Seating: Considerations for the Hands-Free Sitter

Please note: exam questions are subject to change.

1. Which of the following are goals of positioning the hands-free sitter? Maximize reach without loss of position Prevent development of asymmetrical postures Mitigate pressure issues All of the above
2. What is a hands-free sitter? Independent sitter Requires hands on surface to maintain sitting Requires external supports to maintain sitting Cannot be seated
3. Maintaining a seated posture while performing functional tasks requires: Static sitting balance Dynamic sitting balance The correct cushion A pelvic positioning belt
4. What is the purpose of a pre-ischial shelf in a cushion? To prevent pelvic obliquity To distribute pressure To provide stability To prevent forward movement of the pelvis into a posterior pelvic tilt
5. Which of the following is a clinical advantage of a back height just under the scapulae? Transfers Accommodates self-propulsion Posterior pelvic support Less heat retention
6. Lori is a 35 year old woman with the diagnosis of cerebral palsy. She is seated in an ultralight manual wheelchair with a cushion, back, pelvic positioning belt, and anterior lower leg strap. She is a hands-free sitter, can independently transfer and can self-propel her MWC. Lori has limited hip flexion. Her current seat to back angle is 95 degrees. What destructive posture is this most likely leading to? Pelvic obliquity Pelvic rotation Posterior pelvic tilt Anterior pelvic tilt
7. Lori tends to fix in her current seating system in order to stabilize. Recommendations were made to increase stability. Increased stability may also: Reduce muscle tone Reduce posterior pelvic tilt Limit her ability to self-feed Reduce her ability to self-propel
8. Lori has a non-reducible kyphosis. If her seat to back angle is at approximately 90 degrees, how would this impact head position? Tendency toward neck flexion Difficulty keeping the head upright Neck hyperextension All of the above
9. These type of cushions are designed to provide increased postural support and stability through aggressive contours, positioning options, and strong contact. These are not designed for users at high risk of pressure injuries. General use Positioning Custom Planar
10. Given the information presented, what height back would be most appropriate for Lori? To top of shoulders Mid scapulae Under scapulae To top of pelvis
