On June 6, 2011, the Boston Bruins were playing the Vancouver Canucks in game 3 of the Stanley Cup finals. Bruins forward Nathan Horton had passed the puck to his teammate Milan Lucic when he was blindsided by the Canucks’s Aaron Rome, who buried his left shoulder into Horton’s face. Horton’s head was spun backwards, down towards the ice. The back of his head was the first part of his body to make contact with the ice. He was knocked unconscious. His arms became rigid. His eyes rolled back in his head. He had a convulsion.
Nathan Horton was concussed.
Concussion is all too common in sports, particularly those, like ice hockey, that involve body-to-body collisions. Yet it’s still somewhat of a medical mystery. Until the last 10 to 15 years, few physicians or scientists considered concussion significant enough to warrant scientific investigation. Thus, we know very little about it.
