What Is Sled Hockey?

Sled hockey is a sport that was designed to allow participants who have a physical disability to play the game of ice hockey.  It was invented in the early 1960s in Stockholm, Sweden at a rehabilitation center.  Two men from Sweden designed the sledge for ice hockey because they wanted to continue to play hockey despite their recent physical injuries.  
Their design included two skate blades on a metal frame that allowed the puck to pass underneath.  They completed the ensemble by including two round poles with bike handles for sticks.  Although there are many restrictions to the measurements and weight of the sledges used in the Paralympic Games, little has changed from the original design to the ones that exist today.  
It is currently one of the most popular sports in the Paralympic Games.  Essentially all of the rules for stand-up hockey apply to sled hockey.  The differences are those necessitated by the ice sledge and the athlete.
