- Radiating neck pain before the muscle test increases risk of migraine attack
- Neck pain after test triggers migraine attack
- Pain trigger runs through trigeminocervical circuit
Prolonged contraction of the neck muscles triggers a migraine attack, especially in patients with neck pain radiating to the head. German scientists suggest that pain signals originating from the neck activate the trigeminovascular system and thus bring about a migraine attack. They draw that conclusion after investigating 65 patients with migraine and 32 healthy controls on neck pain and then letting them contract their neck flexors and extensor for a long time. Subsequently, they looked at which patients developed head or neck pain during the next day.
