For people with spinal cord injuries, the selection of a wheelchair and sea
ting system involves many factors. This clinical perspective describes a mo
del that includes consideration of the person, the wheelchair, the immediat
e environment between the person and the wheelchair, the intermediate envir
onment of the home and work, and the community environment. The seated post
ure is examined biomechanically, and literature is reviewed that highlights
the differences in the seated position of people with spinal cord injuries
and people without spinal cord injuries. Reports regarding overuse injurie
s of the shoulder and wrists are discussed along with methods of relieving
pressure at the buttock and seat interface. The impact that research findin
gs should have on current clinical practice and the need for more research
to provide evidence to either support or change current practice are discus
sed.
