abstract="To evaluate the 2003 repeal of Pennsylvania's motorcycle helmet law, we assessed changes in helmet use and compared motorcycle-related head injuries with nonhead injuries from 2001-2002 to 2004-2005. Helmet use among riders in crashes decreased from 82% to 58%. Head injury deaths increased 66%; nonhead injury deaths increased 25%. Motorcycle-related head injury hospitalizations increased 78% compared with 28% for nonhead injury hospitalizations. Helmet law repeals jeopardize motorcycle riders. Until repeals are reversed, states need voluntary strategies to increase helmet use. <p>Language: en</p>",
