Wheelchair tennis is one of the forms of tennis adapted for those who have disabilities in their lower bodies. The size of the courts, balls, and rackets are the same, but there are two major differences from able-bodied tennis: athletes use specially designed tennis wheelchairs and the ball may bounce up to two times. The second bounce may also occur outside of the field.
This is one of the official Paralympic sports and also played at Grand Slams. There are three categories; Men, Women, and Quads, and each category has singles and doubles tournaments. Quads is the category for those with quadriplegia. Quads players can hold rackets by using tape to secure the racket to the hand and are allowed to use electric-powered wheelchairs. Wheelchair tennis integrates very easily with the non-disabled game since it can be played on any regular tennis court, with no modifications to the size of the court or the size of rackets or balls.
Wheelchair tennis is often one of the first sports people try after they are injured. This is because it can be played with an able-bodied opponent where the one bounce rule is applied and the disabled athlete would have two.
