Figure 2From: Analysis of right anterolateral impacts: the effect of head rotation on the cervical muscle whiplash responseHead acceleration in the x, y, and z axes of one subject in response to the level of applied acceleration. The z-axis is parallel, the x-axis orthogonal, and the y-axis vertical to the direction of travel. Head X, head acceleration in the x-axis; Head Y, head acceleration in the y-axis; Head Z, head acceleration in the z-axis.Back to article page
