Comparative Study
Pain thresholds and tenderness in neck and head following acute whiplash injury: a prospective study.
OBJECTIVE OF THE INVESTIGATION: In a 6-month prospective study of 141 consecutive acute whiplash-injured participants, and 40 acute, ankle-injured controls, pain and tenderness in the neck/head, and at a distant control site, were measured. ⋯ Focal, but not generalized, sensitization to musculoskeletal structure is present until 3 months, but not 6 months, after whiplash injury, and probably does not play a major role in the development of late whiplash syndrome. Pressure algometry and palpation are useful clinical tools in the evaluation of neck and jaw pain in acute whiplash injury.

In a large-scale study of headache epidemiology in Vågå, Norway, 1838 adult parishioners(18--65 years of age) were examined, and this represents 88.6% of the target group. Jabs and jolts syndrome/idiopathic stabbing headache (ISH) was verified in 35.2% of the questioned parishioners. This prevalence is much higher than previously observed ones. ⋯ The ratio, 1.49, also differs clearly from a previously observed one: 6.6 (P-value = 0.0003, Fisher's exact test). Control studies included blinded re-check of 100 work-ups, with complete concurrence (kappa-value of 1.00 and blinded re-check of 41 individuals (kapp value of 0.841). Jabs and jolts/ISH are frequent and almost the sole shortlasting (generally < 3 s duration) cephalic paroxysms.
