[Whiplash. Epidemiology, diagnosis and treatment].

Recent years have seen an increasing number of car occupants with neck complaints following a car collision and a declining number of persons involved in car crashes--a relationship that is not well understood. Presumably less than 5% will suffer from persistent, (long-lasting), disabling neck pain. Although mostly men are involved in motor vehicle accidents, an equal number of men and women seek emergency care, but it is mostly women, who have persistent (long-lasting) neck complaints after a car collision. In general, there is no documentation of specific injury to the brain or spinal cord from a simple whiplash (WAD 1-3). Whiplash-related neck pain is caused by a distortion of the cervical spine, and, as such, should be interpreted as a benign condition with a good prognosis. Whiplash should be considered a risk factor rather than a medical diagnosis. The association between cause (whiplash mechanism) and effect (symptoms) is poor. Persistent (long-lasting) health problems from a whiplash should be treated like other post-traumatic conditions, and need a bio-psycho-social approach.
