The basic rules of wheelchair basketball are very similar to stand-up, or "able-bodied" basketball. For example, the court dimensions, the height of the basket and the distance to the foul and three point lines, etc., are the same measurements as in the game of stand-up basketball. In 1964, basic international rules were adopted which included minor adjustments to meet the needs of the game in a wheelchair. Wheelchair basketball is designed for players with medically diagnosed disabilities affecting the players lower extremities.
