Quad Rugby, or Wheelchair Rugby as it is also called, is a sport with roots going back to wheelchair basketball and ice hockey, which is not surprising, since it was developed by three Canadians from Winnipeg, Manitoba as a quadriplegic equivalent to wheelchair basketball. The sport was originally called Murderball due to the aggressive nature of the game. It was introduced in the United States in 1981 by Brad Mikkelsen, who with the aid of the University of North Dakota's Disabled Student Service's, formed the first team, the Wallbangers, and changed the game's name from Murderball to Quad Rugby.

In 1979, a team from Winnipeg organized an exhibition at the regional track meet held at Southwest State University in Minnesota. Canada went on to play their first national championship that same year. The first quad rugby match in the US was between North Dakota and Minnesota, as an exhibition game at the 1982 National Wheelchair games, also held at Southwest State University. This same year, the University of South Dakota hosted the first international tournament, with participating teams from Manitoba, Saskatchewan, North Dakota, and Minnesota.

In 1988, the United States Quad Rugby Association (USQRA) was formed to help regulate and promote the sport on both a national and international level. Since its introduction, Quad Rugby has grown to become a truly international sport, with teams now competing from around the globe. There are now more than forty-five organized teams in the United States with many others in the developmental stage. In addition to the teams in the US, there is estimated to be at least twenty international teams from as far away as Australia in addition to those in Canada. Without question, quad rugby is the fastest growing wheelchair sport in the world today.
