Figure 4From: Analysis of right anterolateral impacts: the effect of trunk flexion on the cervical muscle whiplash responseTrunk flexed to left and right. Extrapolated regression plots of the effect that applied acceleration has on the left and right sternocleidomastoid muscles for the variables of peak electromyogram (EMG) (μV), normalized EMG (percentage of isometric maximal voluntary contraction), and the force equivalent of EMG (N).Back to article page
