Abstract
BACKGROUND: High levels of continuous neck pain after a motor vehicle accident (MVA) are reported in cross-sectional studies. Knowledge of this association in general practice is limited. AIM: To compare the differences in perceived pain and disability in patients with acute neck pain due to an MVA versus other self-reported causes. The secondary aim was to identify prognostic factors for continuous neck pain. DESIGN OF STUDY: Prospective cohort study with 1-year follow-up. SETTING: General practices in Rotterdam and its suburban region. METHOD: Patients with non-specific acute neck pain were invited to participate. Questionnaires were collected at baseline and after 6, 12, 26, and 52 weeks. The numerical pain-rating scale (NRS) and the neck disability index (NDI) were measured. Regression analysis was used to identify prognostic factors for continuous neck pain. RESULTS: A total of 187 patients were included. The MVA subgroup (n = 42) was significantly younger (P = 0.007), reported more sick leave (P = 0.037), higher levels of headache (P<0.001) and higher NDI scores at baseline (P = 0.018) but lower scores for previous neck pain (P = 0.015) compared to the remaining cohort. At follow-up the MVA subgroup had higher scores for continuous neck pain (63% versus 40%) and at the NDI (11.0 versus 7.1). After multivariate analysis 'pain in the upper part of the neck' (odds ratio [OR] = 1.6), 'duration of complaints at baseline longer than 2 weeks' (OR = 5.3), and an 'MVA' (OR = 5.3) were significantly correlated with outcome. CONCLUSION: Individuals exposed to MVAs constitute a relevant subgroup of patients with neck pain. An MVA and a longer duration of complaints are prognostic factors for continuous neck pain.
