Cervicogenic headache is a headache that originates from the neck and is one of the most common types of headache. Up to 20% of regular headache sufferers fulfil the cervicogenic headache criteria. Other common headaches include migraines, tension headaches and sinus headaches.
Cervicogenic headache is due to a disorder in the neck which is associated with movement changes in the top 3 vertebra of the neck. The pain associated with this condition is an example of referred pain (i.e. pain arising from a distant source – in this case the neck). This occurs because the nerves that supply the upper neck also supply the skin overlying the head, forehead, jaw line, back of the eyes and ears. As a result, pain arising from structures of the upper neck may refer pain to any of these regions causing a cervicogenic headache.
Although cervicogenic headache can occur at any age, it is commonly seen in people between the ages of 20 and 60. It is twice as common in females as males.
Cervicogenic headache can occur acutely due to loss of movement in the neck or be more continuous due to prolonged load on the neck. There are typically postural causes such as excessive and prolonged slouching when sitting or the opposite, which involves an overcorrected posture. Altered posture can influence how much load is placed on the neck. Too much load over time can lead to pain. Cervicogenic headache is also very common following trauma such as a car accident. Physiotherapist’s are highly skilled in assessing potential contributing factors to cervicogenic headache.
How do we Diagnose a Cervicogenic Headache?
Diagnosis is based on the subjective features of a headache and a thorough Physical examination. Physiotherapist’s are highly skilled is assessing subjective features of cervicogenic headaches, posture and movement of the neck. This is usually sufficient to diagnose cervicogenic headache. Radiology is of limited benefit as common findings on X-Ray overlap with those seen in healthy individuals.
The current diagnostic criteria from the international headach study group include:
There is normally a good response to Physiotherapy treatment for cervicogenic headache. Acute headaches normally respond rapidly to treatment. More chronic and continuous headaches may have a slower response to treatment as it may take times to alter poor posture and movement patterns.
Physiotherapy treatment for this condition can help resolve the headache and focus on contributing factors to help manage the potential for reoccurrence. Treatment and management can include:
