The classification rules of the International Federation for Wheelchair Basketball state that athletes with a physical impairment that affects at least one leg are eligible to compete in the sport at the Paralympics.
Classification also groups athletes in classes, defined by the degree to which they are limited in their ability to perform activities within that sport.
In Wheelchair Basketball there are eight classes from 1.0 for a player with the least physical function, increasing by 0.5 per class through to 4.5 for the most physical function.
To minimise the impact of types of impairment on the outcome of competition, the total on-court point value during play for each team of five players cannot exceed 14.
