"A mobility aid is a device designed to assist walking or otherwise improve the mobility of people with a mobility impairment.
There are various walking aids which can help people with impaired ability to walk, and wheelchairs or mobility scooters for more severe disability or longer journeys which would otherwise be undertaken on foot. For people who are blind or visually impaired the white cane and guide dog have a long history of use. Other aids can help with mobility or transfer within a building or where there are changes of level.
Traditionally the phrase "mobility aid" has applied mainly to low technology mechanical devices. The term also appears in government documents, for example dealing with tax concessions of various kinds. It refers to those devices whose use enables a freedom of movement similar to that of unassisted walking or standing up from a chair." - (en.wikipedia.org 30.07.2021)
