There are no modifications to the size of the court, rackets or tennis balls compared to the able-bodied version of the sport. The main differences are the specially designed wheelchairs and the 'two-bounce rule,' whereby the ball can bounce twice before being hit.

 

There are three categories athletes compete in: men's, women's and quads; each division has singles and doubles tournaments.

 

Athletes compete in a series of tournaments including Grand Slams: The Australian Open, Roland Garros, Wimbledon and US Open, plus the singles and doubles Masters.

 

The sport's global governing body is the International Tennis Federation (ITF). Hong Kong, China Tennis Association Limited is the member of International Tennis Federation and the organization of elite development of Wheelchair tennis in Hong Kong, China.
