Winter in Canada for children is not considered as such, if they don't spend time acceleration sledding down the hill! The tradition of skiing in the canadian sledge passed down from generation to generation. For a long time it was considered one of the safest events of winter.
Unfortunately, the arrival of winter is accompanied by an increase in the number of visits to the emergency departments of hospitals young people with acquired head injuries in the winter activities, including sledding. Fortunately, helmets are known to reduce the risk of head injury, but with so many options available today, helmets, which is the best? Dr. Michael Vasiliadi from Children's hospital of Eastern Ontario (Cheo), fellow of research Institute, together with a research group from the University of Ottawa has put this question on the test. The study is published in the journal of neurosurgery.
"In activities such as sledding or skiing, children are able to achieve very high speeds," explains Dr. Vasiliadi, co-author of this study. "It creates a disproportionate amount of risk with regard to underdeveloped skills children needed to protect yourself in case of unexpected events such as a fall or collision with other people".
There are currently no certified recreational helmets, so parents use what is available to protect the heads of their children. This study compared the protective characteristics of the three types of helmets that are currently used by children aged 7 years and younger. Ice hockey, Alpine skiing, bike riding, all this was tested with the shock strength and the effectiveness of helmets. The surface of the punch and speed were selected to simulate the effects similar to expected for a child while riding in a sleigh.
"We were able to determine the performance of the helmet, the ability of the helmet to reduce the acceleration of the head at impact," said Dr. blaine Hoshizaki, Director of the laboratory at the University of Ottawa, one of the authors of this study. "Helmets are designed and tested to mitigate the risk of injury, they are not intended to eliminate head injuries. Parents must be vigilant and educate their children so that they were safe and having fun outdoors."
