The reverse-edge phenomenon in snowboarding can result in severe head injury. Because a typical backward fall increases the angular acceleration of the head in reverse-edge snowboarding, rotary movement of the head on the frontal-horizontal axis is thought to be harmful. This study found that immobilizing the head reduces angular acceleration on the frontal-horizontal axis during backward falls. Further research is required to analyze additional fall patterns in snowboarding and investigate the risk threshold of kinematic parameters of the head.
