A Cervicogenic headache (CGH) is a type of secondary headache that emerges from a nociceptive source like bony structures, tight fascia, or ligaments present in the atlanto-occipital and cervical joints. The generated pain is non-throbbing in nature and is usually perceived unilaterally in one or more than one region of the head and/or the face. The pain usually starts in the neck and the occiput region, which can radiate to other regions of the head, such as the forehead, orbital region, temples, and vertex, as stated in the early 1980s by a Norwegian neurologist named Ottar Sjaastad. The study aims to delay the occurrence of Cervicogenic headaches in an individual by correcting the biomechanics of the cervical joints. The International Headache Society (IHS) and the Cervicogenic Headache International Society Groups suggested Diagnostic Criteria for Cervicogenic Headaches are used as standard references for this publication (CHISG); also cervical flexion rotation tests are taken as standard references for this journal. Outcome measurements included; Numerical rating pain scale (pain intensity), headache frequency, and the Neck Disability Index (NDI) questionnaire. Postural correction plays an important role in the physiotherapy treatment of Cervicogenic headaches.
