Whiplash: dysfunctional brain-orchestrated pain inhibition in the acute and chronic stage

Pain in Motion previously reported that the brain of patients with chronic pain following a whiplash injury does not activate pain inhibition as it should do (http://www.paininmotion.be/CPMChronicWAD-CR12.html).
Now Pain in Motion has published a new study in Pain Practice, the journal of the World Institute of Pain (http://www.worldinstituteofpain.org/site/home.php), showing that even in the early stage of whiplash pain, pain inhibition is malfunctioning. Pain inhibition was measured using the ‘conditioned pain modulation’ paradigm, previously known as ‘diffuse noxious inhibitory controls’. One can tell why they changed the name. The same study examined whether increased sensitivity to sensorimotor incongruence (or altered perception of distorted visual feedback) relates to the lack of proper pain inhibition in patients with acute whiplash pain, but these issues were unrelated to one another.

Both papers were part of the PhD (doctorate) of Liesbeth Daenen at the University of Antwerp and Vrije Universiteit Brussel, Belgium.
Below you can see Liesbeth together with Enrique Lluch and Rafael Torres-Cueco (University of Valencia, Spain) during a Pain in Motion course last year in Madrid, Spain.
