title: Cervicogenic headache (CEH) after whiplash injury.
abstract: The main objective of the present investigation was to search for cervicogenic headache (CEH) after whiplash injury. Whiplash patients (n= 587), were followed for a year after their emergency service consultation. A total of 222 patients with headache after 1 month went through interview and examinations at 6 weeks, 6 months and 1 year. All included persons received a questionnaire after 1 year. De novo CEH seemed to be present in 8% at 6 weeks and in 3% at 1 year. Previous car accidents, pre-existing headache and neck pain were more frequent in chronic CEH individuals than in those in the cohort without CEH. Range of motion in the neck was reduced in 65% of chronic CEH individuals hours after the accident, compared with 41% in the cohort. Cybex inclinometer, at 6 weeks and 1 year, demonstrated reduced extension in the neck. CEH seems to be present after whiplash injury, particularly in the early phase. It seems similar to, but probably not identical to, non-whiplash CEH.
