Abstract Background The cervical muscles are considered a potential site of whiplash injury and there are many impact scenarios for whiplash injury. There is a need to understand the cervical muscle response under non-conventional whiplash impact scenarios including variable head position and impact direction. Methods Twenty healthy volunteers underwent right anterolateral impacts of and m s2 peak acceleration each with the head rotated to the left then the head rotated to the right in a random order of impact severities. Bilateral electromyograms of the sternocleidomastoids trapezii and splenii capitis following impact were measured. Results At a peak acceleration of m s2 with the head rotated to the right the right trapezius generated 61 of its maximal voluntary
