Who is the RoughRider for?
To avoid potential injury, the RoughRider should only be used by someone who can meet the
following criterion:
Pressure Management
-
The single most important criterion
. If you have limited or no
sensation (feeling) you must be able to manage the pressure on your body to use the
RoughRider safely (e.g., proper techniques for self care, pressure relief, skin care). A pressure
ulcer can form after only 20 minutes of sitting without pressure relief. You must always have an
appropriate, high quality pressure relief cushion (and know how to care for it) to use with the
RoughRider.
Head and Trunk Control
- The RoughRider’s sling-type backrest may not be suitable for you
if you have weak or absent trunk muscles, as you may not have enough muscle support to
maintain a desirable riding position. Using the RoughRider with inadequate trunk control could
lead to the development of scoliosis (curvature of the spine). If you are not able to support your
head independently, you should not use the RoughRider, as it does not provide any head
support.
Size and Fit
– The RoughRider is designed for riders with hip widths between 31.5–48.5 cm*
(12.5–19 in.), and an upper leg length longer than 40.7 cm (16 in.). The length measurement is
taken while seated and measures from back of pelvis to back of lower leg. With some standard
modifications however, the RoughRider may be suitable for riders outside of these ranges. See
end of section for more information. *Seat widths may vary depending on manufacturer.
