Chiropractic, medical and dental research in the 1990s, identified the structures in the cervical spine which were responsible for many headaches (previously diagnosed as tension headache or migraine). These are now identified as cervicogenic headache by the International Headache Society. Clinical trials have now reported that chiropractic management is effective for patients with cervicogenic headache. Source.
