Wheelchairs By Name

Wheelchairs
A wheelchair is a chair with wheels, designed to be a replacement for walking. The device comes in variations where it is propelled by motors or by the seated occupant turning the rear wheels by hand. Often there are handles behind the seat for someone else to do the pushing. Wheelchairs are used by people for whom walking is difficult or impossible due to illness (physiological or physical), injury, or disability. People with both sitting and walking disability often need to use a wheelbench. A basic manual wheelchair incorporates a seat, foot rests and four wheels: two, caster wheels at the front and two large wheels at the back. The two larger wheels in the back usually have handrims; two metal or plastic circles approximately 3/4" thick. The handrims have a diameter normally only slightly smaller than the wheels they are attached to. Most wheelchairs have two push handles at the top of the back to allow for manual propulsion by a second person. Other varieties of wheelchair are often variations on this basic design, but can be highly customised for the user's needs. Such customisations may encompass the seat dimensions, height, seat angle (also called seat dump or squeeze), footrests, leg rests, front caster outriggers, adjustable backrests and controls. A Standing wheelchair is one that supports the user in a nearly standing position. They can be used as both a wheelchair and a standing frame, allowing the user to sit or stand in the wheelchair as they wish. They often go from sitting to standing with a hydraulic pump or electric-powered assist. A mobility scooter is a motorized assist device similar to an EPW, but with a steering 'tiller' or bar instead of the joystick, and fewer medical support options. Mobility scooters are available without a prescription in some markets, and range from large, powerful models to lightweight folding ones intended for travel. A bariatric wheelchair is one designed to support larger weights; most standard chairs are designed to support no more than 250 lbs. (113 kg) on average. Pediatric wheelchairs are another available subset of wheelchairs. Hemi wheelchairs have lower seats which are designed for easy foot propulsion. The decreased seat height also allows them to be used by children and shorter individuals. A knee scooter is a related device which may be substituted for a wheelchair when an injury has occurred to only one leg, below the knee. The patient rests the injured leg on the scooter, grasps the handlebars, and pushes with the uninjured leg. A power-assisted wheelchair is a recent development that uses the frame & seating of a typical manual chair while replacing the standard rear wheels with wheels that have small battery-powered motors in the hubs. A floating rim design senses the pressure applied by the users push & activates the motors proportionately. This results in the convenience, small size & light-weight of a manual chair while providing motorised assistance for rough/uneven terrain & steep slopes that would otherwise be difficult or impossible to navigate, especially by those with limited upper-body function.
