Power Mobility: New Trends and Advances with Power Mobility Part Two: Power Assist Dave Neises, M.Ed, OTR/L, ATP

Sometimes called… PAW: power assist wheels PAPAW: pushrim-activated power-assisted wheelchairs (Nash et al 2008)

What are the Benefits?

In comparison to wheelchairs without power assist: -Less effort and energy -Lower hear rate -Less oxygen consumption -Less activation of upper limb and trunk muscles -Reduced stroke frequency and ROM -Less perceived exertion (Levy et al 2014) and (Nash et al 2008)

Most common power assist options

Comparison Chart enanzeigen/Overview_Active_Drives_USA_ _2.pdf enanzeigen/Overview_Active_Drives_USA_ _2.pdf

E-motion (Alber) [max 286 lbs] Pros -Assist on every push/direction/stopping -Programmability for strength differences Cons: -22 pounds per wheel

Smart Drive (MaxMobility) [max 331 lbs] Pros: - Only 13 pounds -Minimal push strokes -Alternative uses Cons: -Safety awareness -Off-road performance

Twion (Alber) [max 264 lbs] Pros -Only 13 pounds -Assist on every push/direction/ stopping -Smart phone functions Cons: ?

Xtender (Quickie/Sunrise Medical) [max 265 lbs] Pros: -Assist on every push/direction/ Stopping Cons: -38 pounds -Only available on Quickie wheelchairs

Funding Justification -Unable to consistently independently propel a manual wheelchair without power assist wheels. -Unable to independently propel long distances -Upper extremity, neck, or back pain when propelling a manual wheelchair without power assist wheels. Include pain scale 1-10, location, and frequency. -Caregivers unable to consistently independently push their child in a manual wheelchair up hills/inclines/ramps -MUST HAVE TRIALS WITH PAW BEING REQUESTED
