AbstractOBJECTIVE: To reveal whether women with chronic whiplash-associated disorder (WAD) symptoms, grade I-II, demonstrate regional and/or segmental radiographic signs of altered cervical lordosis. DESIGN: Case-control study. SETTING: Radiography department at a university hospital. PARTICIPANTS: Three age-balanced groups comprising 120 women. The case group included women with chronic whiplash syndrome (n = 41), and the control group included women with chronic insidious onset neck pain (n = 39) and an asymptomatic group (n = 40), who were given baseline data. The sample was referred from informed doctors and physiotherapists. INTERVENTION: The women sat in a standardized sitting position and radiographs were taken in a lateral position with fluoroscopic control for alignment. Outcome Measures: Two distinct measurements were taken; 1 of the angles of the upper and lower cervical curvatures, respectively, and 1 of the angles between the inferior borders of each pair of vertebrae in the lower cervical spine. The 3 groups were compared on the ratio of the lower to upper cervical spine angles and on the mean angular values for each segment in the cervical spine. RESULTS: The whiplash group showed a decreased ratio between the lower versus upper cervical spine but comparisons between groups were not statistically significant. The whiplash group was in a significantly more flexed position at the C4-C5 level compared with the asymptomatic group (P =.007). The reliability measures have to be strengthened to render these results definitely conclusive. CONCLUSION: The whiplash group exhibited a different configuration of cervical lordosis. This is clinically important and needs to be studied more closely.
