Classification
Wheelchair rugby players were given a classification based on their upper body function. A committee gave each athlete a 7-level score ranging from 0.5 to 3.5, with lower scores corresponding to more severe disability. During the game, the total score of all players on the court for a team cannot exceed 8 points. However, for each female player on court, their team gets an extra 0.5 points over the 8 point limit.
