This single-blind comparative group design aimed to investigate the sensitivity and specificity of the cervical flexionâ€“rotation test in the diagnosis of C1/2-related cervicogenic headache. This study tested 23 cervicogenic headache, 23 asymptomatic controls and 12 migraine with aura subjects, all aged 18â€“66 years. In stage 1, an experienced manipulative physiotherapist who did not partake in the flexionâ€“rotation test procedure identified C1/2 dysfunction using passive segmental mobility tests in the cervicogenic headache group. Those with C1/2 dysfunction participated in stage 2. In stage 2, using the flexionâ€“rotation test, subjects were tested by two experienced manipulative physiotherapists blinded to the subjectsâ€™ group allocation. The sensitivity and specificity of the flexionâ€“rotation test was 91% and 90%, respectively, with an overall diagnostic accuracy of 91% . The authors conclude that the cervical flexionâ€“rotation test significantly assists in the differential diagnosis of cervicogenic headache and in the identification of movement impairment at the C1/2 segment in patients with cervicogenic headache.
