mixed-gender event. Sledge hockey has become one of the most popular events in the Winter Paralympics since its introduction in the 1994 Winter Paralympics program. On November 30, 2016, as part of an effort to improve and unify the marketing of its self-sanctioned sports outside of the Paralympic Games, and citing that the word "sledge" had differing meanings between languages, the International Paralympic Committee announced that it would henceforth refer to sledge hockey as "Para ice hockey" during the Paralympics and other sanctioned events, and that its sanctioning body would be renamed World Para Ice Hockey. Equipment The sticks have a blade curved at one end in a manner similar to regular ice hockey, and generally six to eight metal teeth at the opposite end of the blade for maneuvering and propulsion. Movement is achieved by using the metal teeth as a means to grip the ice and push oneself forward. The metal teeth cannot be too pointy nor protrude farther than 1 cm beyond the stick, to prevent damage to the ice or injury of other players. Other equipment includes a helmet with facemask, shoulder and elbow pads, shin guards, and hockey gloves. Pants and footwear are at the discretion of both the player's comfort and need. Goaltenders wear the standard mask, chest and arm protector, blocker pad and catching glove, plus a leg pad if they so desire and a stick with teeth on both the paddle as well as the knob of the stick. Additionally, goalies may make modifications to their equipment: a common mod is to attach the plastic outsoles of track spikes onto the outer part of their gloves to aid in lateral mobility. Rules Essentially all of the standard rules of ice hockey apply to sledge hockey. The differences are those necessitated by the ice sled and the athlete. The first set of international rules was created in 1990 and were drafted from Canadian rules. The only penalty unique to sledge hockey is Teeing—the act of charging an opponent using any part of the front radius of the sled. Players with limited mobility in their arms are permitted the use of a non-disabled assistant. Pushers must wear a team jersey and safety equipment, and cannot exceed the speed of the average player on the ice nor can they enter the "house" (the area extending from the goal crease to the end-zone faceoff dots, extended
