Wheelchair tennis first appeared at the Barcelona 1992 Paralympic Games. Its rules are similar to Olympic doubles tennis, in that the ball is allowed to bounce twice, but at least one bounce must be inside the court.
Athletes who are eligible to compete must have permanent substantial or total loss of function in one or both legs. In the quad division, players must have an impairment in three or more limbs.
The events are singles (between two players) and doubles (between two pairs). The winner of a match is determined by the first to win two sets.
