Scientists Kristjansson and Gislason (Medical Faculty, University of Iceland) have compared chronically ill woman with late whiplash syndrome with other women with chronic pain, and a control group of healthy females. Approximately 60 in each of the three groups.
They scanned the women with a load on the head using DMX radiography (video X ray).
Results strongly indicate that the load bearing capacity is impaired in vivo (live test) in women with late whiplash syndrome. Unexpectedly they adopted a rigid horizontal translation strategy with external load applied on their head.
The study that was published in 2017 shows for the first time that the spine after whiplash injury respond like a rigid cylinder when loaded. To carry the head load after whiplash injury, neck muscles, designed for turning the head left/right must instead work to stabilize the head on top of the spine.
This, the authors claim, causes great joint reaction forces through the cervical spine and its injured inert structures maintaining the pain and disability. The latter documented by results from questionnaires.
With this study, people hit by chronic whiplash injury has hope for documentation of physical injury. Only they need to find a clinic that applies the method of DMX scan, which is a type of video X-ray, effective in revealing damage to motoric function of the spine.
