Four Track - Instructional progressions are used for those individuals who
have the strength to independently or with minimal assistance support
themselves, to balance, and to coordinate movements while standing
upright. Generally these individuals ambulate (walk) independently with
the use of assistive aides (forearm crutches, walker, etc.). These
individuals may or may not also use other assistive aides such as
orthotics or braces to help them walk. Four track skiers are able to ski
standing upright on two skis while using (a) two handheld outriggers
(forearm crutches with skis attached at the base of the crutch) or (b) a
modified walker with skis attached, thus providing four points of contact
with the snow. This equipment assists with static and dynamic balance as
well as helping to achieve desired dynamic skiing movements. Four track
skiers may or may not require the use of other specialized adaptive
equipment to provide support to the skis they are standing on (i.e
ski-bra-tip device, spreader bar, etc).
A partial list of those who would
use 4-Track methods includes: persons with cerebral palsy, spina bifida,
traumatic brain injury, etc.
