Cumulative effects of repetitive head impact have been highly associated with short and long term neurological conditions. Despite high rates of head injuries, many people in the U.S. and around the world continue to participate in collision sports. As one approach to address this concern, 2nd Skull has developed supplemental protective headgears including a skull cap, scrum cap and headband that can be utilized in both helmet and non-helmet sports. To test the effectiveness of 2nd Skull products as an adjunctive tool to reduce the severity of head impact, data were extracted from a series of tests completed at four sites under laboratory conditions using linear, projectile and rotational impactor to simulate blows to the head in sports. The majority of test cases showed the same pattern of reduced impact severity with the addition of 2nd Skull padding. It remains to be seen if these laboratory results will translate to the field.

第二种头骨产品在模拟运动中减少头部撞击的功效

重复性头部撞击的累积效应与短期和长期神经系统疾病高度相关。尽管头部受伤率很高，但美国和世界各地的许多人仍在继续参加碰撞运动。作为解决这一问题的一种方法，第二头骨公司已经开发出了补充性防护帽，包括可用于头盔和非头盔运动的骷髅帽，稀有帽和头带。为了测试第二副头骨产品作为减少头部撞击严重性的辅助工具的有效性，从实验室条件在四个位置完成的一系列测试中提取了数据，使用线性，射弹和旋转撞击器模拟了运动中对头部的打击。大多数测试用例在添加第2个Skull填充后显示出相同的降低冲击严重性的模式。这些实验室结果能否转化为实地，还有待观察。
