Wheelchair Mobility: Power Add On Options And Use For Manual Wheelchairs

---

1.  Alternate Drive Mechanisms are appropriate for which manual wheelchair user? A user with upper extremity injury and pain A user who cannot manage slopes or long distances without assistance A user who is less efficient due to aging All of the above

2.  Which of the following are NOT considered an Alternate Drive Mechanism? Lever drives Arm-crank drives Add on joystick and power wheels PAPAWs

3.  What does PAPAW stand for? Power assist power activated wheel Pushrim-activated power assist Grandpa Power activated pushrim wheel

4.  Which of the following systems may include gears? Reverse pushrim drives Lever systems Armcrank systems All of the above

5.  When would a user choose Continuous Mode on a PAPAW? Long distances Within the home Slopes Uneven terrain

6.  DeShawn is a 13 year old young man with the diagnosis of Transverse Myelitis. He is currently using an ultralight MWC with customized seating. He can propel throughout his school, but slowly and with fatigue. What would be a medical justification for an Alternate Drive Mechanism? Increased speed Increased distance Increased cost Reduce the risk of repetitive stress injuries

7.  What would be functional justifications for an Alternate Drive Mechanism? Decreased independence in a variety of environments Energy conservation to allow other tasks to be completed Cost Larger footprint

8.  What was a primary reason that PAPAWs were recommended instead of a PWC? They look cool Cost The vehicle was not accessible They hold a charge for longer

9.  The funding source requested proof that use of PAPAWs would actually increase efficiency. What strategies could be used? Time tests before and after PAPAWs were placed Propulsion tests before and after PAPAW were placed Documentation of situations in which DeShawn was dependent for mobility and independent with the PAPAWs All of the above

10.  What is an advantage to using a Reverse Pushrim Drive? Posture during propulsion More intuitive Decreased cost Lower weight
