Wheelchair Mobility: Ultralight Configuration And Propulsion

---

1.  Which of the following are considered complex rehab equipment? Lightweight manual wheelchairs Ultralightweight manual wheelchairs Pediatric manual wheelchairs All of the above

2.  Which characteristic best explains why rigid frames are more efficient to propel? Lighter weight Energy is transferred into the ground instead of into a moving frame Smaller footprint Small front casters

3.  What measurement determines correct rear seat height when using an ultralight manual wheelchair? The size of the rear tire The length of the lower legs The user's elbow should be at 120 degrees when hand is resting on top of the wheel Center of gravity

4.  If the wheelchair is tippy rearward, what adjustment should be considered? Move the user's weight rearward Increase camber Move the rear wheel anteriorly Move the rear wheel posteriorly

5.  Lori is a 35 year old woman with the diagnoses of cerebral palsy and arthritis. She is currently in an ultralight manual wheelchair which she is able to self-propel. She has come in for assessment to improve her propulsion efficiency. When asked to hang her arm down from her shoulder to her side, her middle finger is several inches above the axle of the rear wheel. What adjustment is indicated? Raise rear seat height Immediately switch to power Trial smaller wheels Lower rear seat height

6.  Lori needs to pop a wheelie to get over curbs but is unable to do so in her wheelchair. What adjustment should be considered? Move rear wheel back / posterior Move rear wheel forward / anterior Trial a power wheelchair instead Increase wheel camber

7.  Lori is interested in making her rigid ultralight manual wheelchair even lighter. This could be accomplished by which of the following: Replacing tire solid inserts with pneumatic inserts Considering a lighter weight cushion Considering a lighter weight back All of the above

8.  Lori's rear wheels rub on her clothing at times, leaving marks. Which would be an appropriate solution? Move the rear wheels out laterally even if it affects propulsion Increase camber Recommend a "clothing guard" in between the rear wheel and the lateral pelvis Tell her to wear dark pants only

9.  What is NOT an advantage of a tighter front frame bend? Smaller footprint Improved maneuverability Accommodates tight hamstrings Larger footprint

10.  Which propulsion technique is most efficient? Semicircular Single loop over Double loop over Arcing
