Abstract Background The cervical muscles are considered a potential site of whiplash injury and there is a need to understand the cervical muscle response under non-conventional whiplash impact scenarios including variable body position and impact direction. There is no data however on the effect of occupant position on the muscle response to frontal impacts. Therefore the objective of the study was to measure cervical muscle response to graded right anterolateral impacts. Methods Twenty volunteers were subjected to right anterolateral impacts of and m s2 acceleration with their trunk flexed forward 45 degrees and laterally flexed right or left by 45 degrees. Bilateral EMG of the sternocleidomastoids trapezii and splenii capitis and acceleration of the sled torso and head were .
