Developed in Canada in 1976, the sport’s original name was murderball. Wheelchair rugby is played indoors on a hardwood court. The rules include elements of wheelchair basketball, ice hockey, handball, and rugby union. It is a contact sport and physical contact between wheelchairs is an integral part of the game.
Unlike traditional rugby, wheelchair rugby is played with a spherical ball. This ball is similar in appearance to a volleyball.
