Wheelchair Curling had its debut at the Torino 2006 Paralympic Winter Games. The sport is open to male and female athletes with a physical impairment in the lower part of the body. This includes athletes with significant impairments in lower leg/gait function who require a wheelchair for daily mobility. Each team must be comprised of male and female players. It is governed by and played according to the rules of the World Curling Federation (WCF), with only one modification – no sweeping.
