Potential interactions between peripheral and central mechanisms in patients with chronic whiplash : does reduction in white matter integrity play a role in this traumatic event?

The aim of this project is to explore the interrelationship between changes in muscle function, central pain mechanisms and white matter integrity in patients with chronic whiplash associated disorders (WAD). 35 subjects in each group (traumatic neck pain, non-traumatic neck pain and healthy controls) will undergo a series of investigations, including evaluation of muscle performance, muscle properties, white matter integrity and central pain mechanisms.
