Wheelchair tennis is one of the forms of tennis adapted for those who have disabilities in their lower bodies. The size of courts, balls and rackets are the same, but there are two major differences from pedestrian tennis; athletes use specially designed wheelchairs and the ball may bounce up to two time. The second bounce may also occur outside the court.
Wheelchair tennis is played at Grand Slam, and is one of the sports contested at the Summer Paralympics. There are three categories; Men, Women and Quads; each category has singles and doubles tournaments.
