Power Assist


Whether you’re sightseeing on vacation or running your day-to-day errands, power assist can give you a little bit of an extra push when you need it most. While power assist isn’t new, thanks to advancements in technology and design, more options are currently available than ever before.


In the simplest terms, power assist provides manual wheelchair users with power when they need it.

Power Assist:

  • Requires less force to propel, reducing the number of pushes needed to go the same distance;
  • Makes it easier to propel over difficult terrain such as grass, gravel, carpet, curb cuts, ramps and inclines;
  • Allows users to do more while using less energy, which helps fight fatigue and overuse injuries, such as carpal tunnel and rotator cuff problems.

Power Assist Perks:

GREATER CONNECTIVITY: Bluetooth gives you the ability to control speed and customizable settings with an
app. It’s now possible to control some products without being in the chair, making it easy to store when not being used.
SAFETY: Many products offer increased speed to cross busy streets or assisted braking when going downhill, helping to make daily life a little more safe.
IMPROVED DRIVABILITYAND TRANSPORTABILITY: Thanks to continued innovations, products continue to get lighter and easier to remove for travel, while engines are becoming stronger and more efficient, helping you get where you’re going with a little less hassle.


Manual wheelchair users have two main options when it comes to power assist: power assist wheels or an add-on unit. In deciding between the two, experts suggest taking stock of your goals and finding the right combination of options that fit your lifestyle. You and your care team should consider functional and comfort levels as well as safety when making decisions about which product might work best. If you qualify, power assist may be covered by insurance, whether you’re a new or existing user. Private pay options are also available. If you have questions, consult your doctor, therapist or National Seating & Mobility.
