Mobility devices consisting of a chair mounted on wheels, designed to assist people with mobility impairments in moving around.
Compound of 'wheel' from Old English 'hweol' and 'chair' from Old French 'chaiere.' The first self-propelled wheelchair was invented in 1655, but the modern lightweight designs emerged in the 20th century with advances in materials and engineering.
The evolution of wheelchairs reflects changing attitudes toward disability - early versions were heavy, institutional objects that emphasized limitation, while modern designs prioritize independence and athletic performance. Paralympic sports have revolutionized wheelchair technology, creating devices that enhance rather than merely accommodate human capability.
