Sled hockey (also called 'Sledge' outside the U.S.) is an adaptive form of ice hockey for youth and adults who cannot skate in a standing position due to a physical disability. It was invented at a rehabilitation center in Sweden in the early 1960s by a group of Swedes who, despite their physical challenges wanted to continue playing hockey.
Sled hockey is played the same as able-bodied (standing) ice hockey except it is played in specially designed 'sleds'. Players sit in 'bucket seats' that sit on top of two hockey skate blades. There are two sticks for each player. These modified sticks have a hockey skate blade on one end for hitting the puck and metal pics on the other end for propelling themselves. Goalies wear basically the same equipment and sit in a sled but make modifications to their gloves to assist them in manuverability.
Sled hockey has been a Paralympic sport since 1994 with the USA winning their second gold in 2010 in Vancouver at the winter Paralympics.
