Headache is one of the most common presenting complaint of chiropractic patients. A recent study compared the findings and identified the diagnostic accuracy of the cervical flexion-rotation test (FRT) between subjects with probable cervicogenic headache (CGH), migraine without aura (Migraine), and multiple headache forms (MHF).
Sixty subjects were evaluated: 20 with CGH, 20 with Migraine, and 20 with MHF. The average range of unilateral rotation to the most restricted side was 25 degrees, 42 degrees and 35 degrees for groups CGH, Migraine and MHF, respectively. Range of rotation was significantly reduced in the CGH group when compared to groups Migraine and MHF. The study found that “An experienced examiner using FRT was able to make the correct diagnosis 85% of the time (P<0.001)…”
This recent research continues to confirm the importance of a simple flexion rotation test (FRT) in the differential diagnoses of headaches. Many headache cases are often similar in terms of presenting symptom and the FRT has demonstrated in multiple research studies to be highly sensitive to identifying cervicogenic headache from migraine and multiple headache forms.
