Clinical Examination and Trigeminocervical Convergence

Revisiting an Overlooked Interface: The Research Context Recent neurophysiological evidence confirms that upper cervical and trigeminal nerve fibres converge within the trigeminocervical complex. As a result of this convergence, signals from the neck can influence migraine symptoms, even though migraines remain classified as a primary disorder. Key Findings Across Contemporary Literature Research identifies the following: shared pain processing between the neck and the trigeminal regions,

• heightened sensitivity in brainstem regions responding to extracranial signals,
• and a reciprocal interaction between neck and head pain pathways.

Together, these findings align with clinical observations, notably that neck symptoms often precede migraine attacks. Clinical Interpretation The evidence suggests that a physical examination may identify functional issues rather than structural damage. Extra-cranial signals may heighten central sensitivity, supporting a combined neurological and physical assessment. Take-Home Message New research refines our understanding of migraine mechanisms without altering classification. Thus, examination remains essential for comprehensive headache assessment.
