Purpose : This study examined the comorbidity of whiplash and post-tra
umatic stress disorder (PTSD) following motor vehicle accidents. A tre
atment strategy in cases with both disorders is proposed. Method: A re
view of the literature on psychological consequences of motor vehicle
accidents and on risk factors associated with developing chronic whipl
ash complaints is given. A case report is presented to illustrate the
treatment strategy. Results: Traffic accidents lead to psychological c
omplaints more often than is realized in clinical practice. It is esti
mated that PTSD occurs in at least 25% of traffic accident victims who
sustain physical injuries. This number is probably higher in patients
with chronic whiplash complaints. The case report shows that improvem
ent in relation with the post-traumatic stress symptoms can have a ben
eficial effect on coping with the chronic whiplash complaints. Conclus
ions: The psychotherapeutic treatment of patients with chronic whiplas
h complaints and PTSD should be aimed primarily at coping with the tra
uma and not at the chronic pain complaints.
