• Active user wheelchairs were originally designed
for use in sport, but as they are very light and adjustable, they can
suit older and frailer users who find a standard wheelchair hard work.
• Key features include: frames that are available
in a range of sizes; quick-release wheels; multiple axle positions;
rear wheels that can be moved forwards, which means that the chair can
not only be propelled with much less effort, but the front castors can
also be lifted from the ground more readily, making it easier to negotiate
kerbs and other obstacles.
• Cambered wheels - wheels that are set at an
angle to the vertical make it easier both to steer a straight course,
and to turn the chair. A camber of up to 5° gives the benefit of
easier manoeuvrability, without making the width of the chair so great
that it become difficult to get through doors and narrow passageways.
• Backrests on active user wheelchairs may be
lower in height than on standard chairs, providing just enough support
for the lumbar region, while leaving the arms completely free to propel
the chair without hindrance. Some active user chairs have an angle-adjustable
backrest, for greater support.
• Materials - aluminium alloy is much lighter
than steel, although a bit more expensive. Greatest lightness and strength
is provided by carbon fibre or titanium, but these materials are a lot
more expensive, and can be hard to repair - although they won't corrode.
