Manual and electronic wheel chairs
 
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
 
Manual Wheelchair
  • Manual wheelchairs are those that require human power to move them. Many manual  wheelchairs can be folded for storage or placement into a vehicle, although modern wheelchairs are just as likely to be rigid framed.
  • Manual or self-propelled wheelchairs are propelled by the occupant
  • The user moves the chair by pushing on the handrims, which are made of circular tubing attached to the outside of the large wheels
  • The handrims have a diameter that is slightly less than that of the rear wheels
  • Skilled users can control speed and turning and often learn to balance the chair on its rear wheels do a "wheelie".
  • The wheelie is not just for show a rider who can control the chair in this manner can climb and descend curbs and move over small obstacles.
  •  Foot propulsion of the wheelchair by the occupant is also common for patients who have limited hand movement capabilities or simply do not wish to use their hands for propulsion.
  • Foot propulsion also allows patients to exercise their legs to increase blood flow and limit further disability.
  •  One-arm drive enables a user to guide and propel a wheelchair from one side. Two handrims, one smaller than the other, are located on one side of the chair, left or right. On most models the outer, or smaller rim, is connected to the opposite wheel by a folding axle.
When both handrims are grasped together, the chair may be propelled forward or backward in a straight line.
 
 
Electronic Wheelchair
  • An electric-powered wheelchair is a wheelchair that is moved via the means of an electric motor and navigational controls, usually a small joystick mounted on the armrest, rather than manual power.

  • For users who cannot manage a manual joystick, headswitches, chin-operated joysticks, sip-and-puff or other specialist controls may allow independent operation of the wheelchair.

  • 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.
