Sled hockey - also referred to as sledge hockey outside of the U.S. - originated at a rehab center in Stockholm, Sweden in the early 1960's by a group of Swedes who wanted to continue to play hockey.
Sled Hockey follows most rules as stand-up ice hockey with the main difference being equipment. Players sit in a specially designed sled that sits on two skate blades and use two sticks with metal picks on the end use to help propel themselves across the ice. Goalies most of the same gear and have a metal picks sewn to the back side of the glove to help with maneuvering.
