Validation of a new system measuring head impact biomechanics

2010年，加拿大医院诊断出约10万例脑震荡，其中约三分之二与运动有关。一家加拿大电子制造公司Artaflex（Markham，安大略加拿大）已经制造了一种三轴线性加速度计和陀螺仪系统，该系统安装在运动员的头盔内;当运动员在参加运动时受到冲击时，该系统能够测量线性和旋转加速度（Gforcetracker-GFT）。该公司有兴趣获得援助，开发一种分析方法，使用GFT信号来预测足球运动员头部在撞击过程中的加速度。我们建议同时测量头部加速度，使用拟人测试假人（碰撞测试假人头型）和GFT数据的一系列控制的影响，使用线性冲击器，导致线性和角加速度。我们的分析将集中在GFT输出和头部加速度之间的关系建模。

Approximately 100,000 concussions were diagnosed in Canadian hospitals in 2010 and approximately two-thirds were sports related. A Canadian electronics manufacturing company, Artaflex (Markham, Ontario Canada), have manufactured a tri-axial linear accelerometer and gyroscope system that fits within athlete's helmets; it is capable of measuring the linear and rotational accelerations when an athlete receives an impact while participating in sports (Gforcetracker - GFT). This company is interested in receiving assistance developing an analysis approach that would use the GFT signals to predict the acceleration of the football player's head during impacts. We propose to concurrently measure head accelerations using an anthropomorphic test dummy (crash test dummy headform) and GFT data for a series of controlled impacts using a linear impactor resulting in linear and angular accelerations. Our analysis will focus on modelling the relationship between the GFT outputs and the accelerations of the head.
