Abstract : The incidence of cerebral concussion incurred during impact conditions has been shown to be related to the levels of angular acceleration which a head undergoes during impact. Also, since the forces causing angular acceleration of the head during impact are transmitted by neck structures, measurement of head angular accelerations may give a good indication of neck injury potential in various impact situations. Studies relating these injuries to head angular acceleration values have been hampered in the past by the lack of an accurate technique for measuring angular acceleration. We have developed a system employing linear accelerometers mounted on the subject's head and oriented in such a manner that the tangential acceleration of one point on the head is found relative to another point and subsequently angular acceleration is determined. This system has shown improved accuracy in angular acceleration measurement over previously used methods and should aid in the study of head and neck injuries during impact. (Author)
