Summary

The use of safety helmets clearly decreases the risk and severity of head injuries as
compared to non-helmeted participants in skiing and snowboarding. The beneficial effects
of helmets are not negated by unintended risks as their use does not appear to increase the
risk of neck or cervical spine injury as compared to non-helmeted participants in skiing and
snowboarding. The use of safety helmets also does not appear to increase the risk of
compensation behavior as compared to non-helmeted participants in skiing and
snowboarding. Therefore, helmets are strongly recommended during recreational skiing and
snowboarding. Limitations in current studies have been highlighted and need to be
appropriately addressed in future investigations on the subject.

Гранты в этой области не соизмеримы с фарминдустрией и маловероятно, что бенефициаром в этом скромном исследовании кто-то является) Так что, хочется в верить )
