4 point player
4 point player is a disability sport classification for wheelchair basketball.
The classification was created by the International Paralympic Committee and has roots in a 2003 attempt to address "the overall objective to support and co-ordinate the ongoing development of accurate, reliable, consistent and credible sport focused classification systems and their implementation."
This classification is for wheelchair basketball. Classification for the sport is done by the International Wheelchair Basketball Federation. Classification is extremely important in wheelchair basketball because when players point totals are added together, they cannot exceed fourteen points per team on the court at any time. Jane Buckley, writing for the Sporting Wheelies, describes the wheelchair basketball players in this classification as players having: "Normal trunk movement but some reduced lower limb function as they unable to lean to both sides with full control." The Australian Paralympic Committee defines this classification as: "Players with normal trunk movement, but usually due to limitations in one lower limb they have difficulty with controlled sideways movement to one side." The International Wheelchair Basketball Federation defines a 4 point player as "Normal trunk movement, but usually due to limitations in one lower limb they have difficulty with controlled sideways movement to one side." The Cardiff Celts, a wheelchair basketball team in Wales, explain this classification as, "able to move the trunk forcefully in the direction of the follow-through after shooting. Class 4 players are able to flex, extend and rotate the trunk maximally while performing both one-handed and two-handed passes and can lean forward and to at least one side to grasp an over-the-head rebound with both hands. Class 4 players are able to push and stop the wheelchair with rapid acceleration and maximal forward movement of the trunk. Typical Class 4 Disabilities include : L5-S1 paraplegia, with control of hip abduction and extension movements on at least one side. Post-polio paralysis with one leg involvement. Hemipelvectomy. Single above- knee amputees with short residual limbs. Most double above-knee amputees. Some double below-knee amputees." 
4 point players and 4.5 point players receive less playing time than 1 point players because of their higher point value.
On court ability
4 point players can move their wheelchairs at a significantly faster speed than 1 point players.
There is a significant difference in special endurance between 2 point players, and 3 and 4 point players, with 2 point players having less special endurance.
In games, 4 point players steal the ball three times more often than 1 point players. 4 point players generally have the greatest number of rebounds on the court because of competitive advantage when under the basket in terms of height, stability and strength. 4 point players turn over the ball with much greater frequency than 1 point players.
Wheelchair basketball players who are going to compete at the 2012 Summer Paralympics in this classification need to have their classification be in compliance with the system organised by the IWBF and their status being listed as ‘Review’ or ‘Confirmed’.
In Australia, wheelchair basketball players and other disability athletes are generally classified after they have been assessed based on medical, visual or cognitive testing, after a demonstration of their ability to play their sport, and the classifiers watching the player during competitive play.
Once a player is classified, it is very hard to be classified into a different classification. Players have been known to have issues with classification because some players play down their abilities during the classification process. At the same time, as players improve at the game, movements become regular and their skill level improves. This can make it appear like their classification was incorrect.
Wheelchair Twin Basketball is a major variant of wheelchair basketball. This version is supposed by the International Stoke Mandeville Wheelchair Sports Federation,  and played in Japan. Twin basketball has a three-point classification system based on the evaluation of the mobility of people with cervical cord injuries. In this variant, the equivalent to 4 point players would be players without a head band. These players are "Players without a headband (no band players) - the players possess good triceps, a good balance of the hand and some finger functions. They can score by shooting with a smaller and lighter basketball to the normal basket."
