In the 1960s, when helmets were coming into greater use, Ip writes, “Football related deaths declined but the number of quadriplegics and broken necks went up.” He continues, “The helmet has changed players’ behavior by allowing them to hit each other with their heads and when that happens the neck and spine form a single axis and the force of the blow is fully loaded onto the spinal column.” The game of hockey saw similar unintended consequences, after helmets became mandatory in the National Hockey League in 1979
