the International Stoke Mandeville Games Federation (ISMGF) established the first sub-section for wheelchair basketball. At that time, ISMGF was the world governing body for all wheelchair sports. In 1989, ISMGF accepted for its former wheelchair basketball sub-section to be named International Wheelchair Basketball Federation (IWBF). Full independence came in 1993 with the IWBF becoming the world body for wheelchair basketball with full responsibility for development of the sport. Over the following years, IWBF membership grew in size, and based on the number of National Organizations for Wheelchair Basketball (NOWBs) with active programs, the international federation configured itself into four geographical zones: Africa, Americas, Asia/Oceania and Europe. Wheelchair Basketball World Championship World championships for the sport have been held since 1973, with Bruges, Belgium being the first host city. The first world championship for men was won by Great Britain. Of the first 11 men's world championships, six were won by the United States (1979, 1983, 1986, 1994, 1998, 2002), two were won by Great Britain (1973, 2018), two were won by Australia (2010, 2014); and once each by Israel (1975), France (1990) and Canada (2006). Canada has won five of the women's world championship titles (1994, 1998, 2002, 2006, 2014), the United States two (1990, 2010) and the Netherlands one (2018). Rules Wheelchair basketball retains most major rules and scoring of basketball, and maintains a 10-foot basketball hoop and standard basketball court. The exceptions are rules which have been modified with consideration for the wheelchair. For example, "travelling" in wheelchair basketball occurs when the athlete touches their wheels more than twice after receiving or dribbling the ball. The individual must pass, bounce, or shoot the ball before touching the wheels again. In some countries, such as Canada, Australia, and England, non-disabled athletes using wheelchairs are allowed to compete alongside other athletes on mixed teams. Classifications Classification is an international regulation for playing wheelchair basketball to harmonize players' different levels of disabilities. All teams which compete above a recreational level use the classification system to evaluate the functional abilities of players on a point scale of 1 to 4.5. Minimally disabled athletes are classified as a 4.5, and an individual with the highest degree of disability (such as a paraplegic with a complete injury below the chest) would be classified as a 1.0. Competitions restrict the number of points allowable on the court at one time. The five players from each
