Do cycle helmets prevent serious head injury? Cycling without helmets.

This article discusses research into the efficacy of cycle helmets in preventing serious head injury. The main scientific study undertaken in five hospitals in Seattle is criticized because the cyclists used in the study were not matched for risk taking behaviour. In other words, the study did not discount the possibility that cyclists with head injuries were very different from those with other injuries. An observational study in the same city indicated that this was likely. It showed that children wearing helmets were much more likely to be white rather than black, to be riding in parks and on bicycle paths than on city streets, and riding with adults rather than riding alone. Such children are therefore less likely to be involved in serious accidents than those who do not wear helmets. Helmets may also give a sense of false security because although they may lessen direct compression, they do not protect the brain from rotational injury. The British Standard 6863 for cycle helmets specifies that the helmet protects only when the rider falls onto the road without other vehicles being involved. Most cyclists usually die from being hit by a car. A plea is made to reduce car traffic.
