New Delhi, Mar 06 (ANI): Turns out, helmet use is associated with reduced risk of cervical spine injury during motorcycle crashes. According to a study conducted at the University of Wisconsin, during an accident, helmet use lowers the likelihood of cervical spine injury (CSI), particularly fractures of the cervical vertebrae, despite the claims that helmets do not protect the cervical spine during a motorcycle crash and may even increase the risk of injury. Wearing a helmet decreases the incidence and severity of traumatic brain injury during crashes. What then are the objections to universal laws requiring motorcycle helmet use? Major reasons cited for not requiring helmets while riding a motorcycle include freedom of choice, avoiding any limitation on vision, and a perceived increased risk of receiving a cervical spine injury (CSI). This last reason is based on the belief that the added weight of a helmet might increase torque on the cervical spine. There were no significant differences between groups (helmeted vs. un-helmeted riders) with respect to other types of cervical spine injuries that were sustained: nerve root injury, cervical strain, or cord contusion.
