Individual events are divided into three groups: visually impaired, standing, and sitting, depending on the disability of the athlete. The results of each group are multiplied by the appropriate grading factor to determine the final results.

The race route requires about one-third uphill, one-third downhill and one-third undulation. In general, the standing and visually impaired groups have a more difficult course than the seated group, while the seated group has a relatively less difficult course with fewer drops and angles, and a relatively easier course.

The traditional technical competition field needs to press the special snow chute; the free technical competition field needs to be wide and flat, and there is no restriction on technical movements. The relay program requires athletes to alternate between traditional and free techniques.

Equipment

Seat ski chairs, including seat belts and suspension devices, are designed to be as light as possible to minimize the burden on the athlete and to reduce physical exertion.

No springs or other elastic parts can be installed in the seat connections and the seat is not adjustable to the snowboard. Non-elastic straps must be used to secure the athlete's thighs to the seat.

Standing athletes may compete with two, single or no poles, depending on their physical condition.

Athletes who are totally or almost totally blind will be required to wear an eye patch and will be guided through the race by a skate leader using a loudspeaker, and athletes with low vision will have the option to race with or without a skate leader.
