Power assist and propulsion devices

Attachable devices or replacement wheels can assist propulsion and extend a wheelchair’s capabilities.

Potential benefits include reduced upper-limb strain and easier travel over longer distances or challenging terrain. People with limited strength or existing arm and shoulder problems may particularly value reduced effort.

Added forces and changes in stability can increase equipment damage and tipping risks. A manual chair’s frame may not be designed for the new forces.

Consider hand function, attachment needs, terrain, compatibility, transport, and professional assessment. Adapted controls may help some users with limited hand movement.

Non-powered options include devices that lift casters and mechanisms that amplify pushing effort. Larger front wheels can make uneven surfaces easier to negotiate.

Powered options include motorized wheels and front- or rear-mounted assistance. Pushrim-activated wheels amplify the user’s pushing, turning, and braking input.
