Power soccer is the first competitive team sport designed and developed specifically for power wheelchair users. Athletes' disabilities include quadriplegia, muscular dystrophy, cerebral palsy, arthrogryposis and many others. The game is played in a gymnasium on a regulation basketball court. Two teams of four players attack, defend, and spin-kick a 13-inch soccer ball in a skilled and challenging game similar to able-bodied soccer.
