Repeated mild traumatic brain injury: mechanisms of cerebral vulnerability.

abstract：:The pattern of injuries in restrained victims of motor vehicle crashes (MVCs) remains an issue of debate. We investigated the association of peripheral nerve injuries with the use of protective devices (seat belt and air bag) during MVCs. We performed a retrospective cohort study of 384,539 adult MVC victims who were ...
