=== Wheelchairs ===
{{Main|Wheelchair}}
Wheelchairs are devices that can be manually propelled or electrically propelled, and that include a seating system and are designed to be a substitute for the normal mobility that most people have. Wheelchairs and other mobility devices allow people to perform mobility-related [[activities of daily living]] which include feeding, toileting, dressing, grooming, and bathing. The devices come in a number of variations where they can be propelled either by hand or by motors where the occupant uses electrical controls to manage motors and seating control actuators through a [[joystick]], [[sip-and-puff]] control, [[head switches]] or other input devices.<ref>Francisco Sandoval, et al. "Wheelchair Collaborative Control For Disabled Users Navigating Indoors." Artificial Intelligence in Medicine 52.3 (2011): 177–191. Academic Search Complete. Web. 9 April 2013</ref> Often there are handles behind the seat for someone else to do the pushing or input devices for caregivers. Wheelchairs are used by people for whom [[walking]] is difficult or impossible due to illness, injury, or disability. Ambulatory wheelchair users may also use other devices, such as walkers. 

Newer advancements in wheelchair design enable wheelchairs to climb stairs, go off-road or propel using [[segway]] technology or additional add-ons like [[Handcycle|handbikes]] or [[Wheelchair power add-on|power assists]].
