How to diagnose cervicogenic headaches after a whiplash injury

This excerpt from Whiplash, Headache, and Neck Pain focuses on cervicogenic headache, a secondary headache stemming from cervical musculoskeletal issues. The text differentiates cervicogenic headache from primary headaches like migraine and tension-type headaches, highlighting symptomatic overlap and the challenges in diagnosis. It explores various diagnostic methods, including physical examination, and emphasizes the need for a pattern of physical impairments (reduced range of motion, painful upper cervical joint dysfunction, and muscle impairment) to confirm a diagnosis of cervicogenic headache. The authors also discuss the effectiveness of manipulative therapy and therapeutic exercise for this specific headache type.
