Cervicogenic Headaches
Normal Anatomy
There is a vast amount of soft tissue and joints within the upper cervical spine.
The suboccipital nerve branches from C1 nerve root and supplies muscles of suboccipital region and atlano-occipital joint which is purely motor without any sensory aspect.
Greater occipital and lesser occipital nerves branch from C2 nerve root and supplies C1/2 and C2/3, vertex and posterior scalp
Third Occipital nerve branches from C3 nerve root and supplies the lower scalp and C2/3
The trigeminal nerve and upper cervical spinal nerves in the brain share a common “Trigeminocervical nucleus”
The structures innervated by C1,2,3 spinal nerves are
Atlanto occipital joint
Ligaments of the atlanto-occipital joint
C2,3 facet joints
Sub-occipital and upper posterior neck muscles
Upper cervical spinal dura mater
Verterbral arteries
C2-3 intervertebral discs
Trapezius and SCM muscles
Pathophysiology
Dysfunction to the any structure supplied by the upper cervical nerves can cause pain anywhere within the distribution of these nerves
This often results in “Cervicogenic Headaches” i.e a headache due to a cervical origin
Mechanism of Injury
Traumatic
Insidious
Poor Posture
Muscular Imbalance
Degenerative Disc Disease/Spondylosis

Pain Character
|
Non- throbbing and non- lancinating, pain usually starts in the neck
|
Throbbing , pulsating
|
Dull
|
Triggers
|
Neck Movement and postures, limited ROM, pressure over C0-C3
|
Multiple , neck movement not typical
|
Multiple, neck movement not typical
|
Associated Symptoms
|
Usually absent or similar to migraine but milder, decreased ROM
|
Nausea, vomiting, Visual changes, phonophobia, photophobia
|
Occasionally decreased appetite, phonophobia or photophobia
|
Classification
Cervicogenic Headache International Study Group Diagnostic Criteria
Major Criteria
|
Symptoms and signs of neck improvement
Precipitation of comparable symptoms by:
Neck movements and/or sustained , awkward head positioning and/or
External pressure over the upper cervical or occipital region
Restriction of range of motion in the neck
Ipsilateral neck, shoulder or arm pain.
Unilaterality of the head pain, without side shift
|
Head Pain Characteristics
|
Moderate – severe, non-throbbing pain, usually starting in the neck. Episodes of varying duration, or fluctuating, continuous pain.
|
Other Characteristics of some importance
|
Only marginal or lack of effect of indomethacin. Only marginal of lack of effect of ergotamine and sumatriptan. Female gender. Not infrequent history of head of indirect neck trauma, usually of more than medium severity.
|
Other Features of Lesser Importance
|
Various attack- related phenomena, only occasionally present , and /or moderately
expressed when present
a. Nausea
b. Phono-and photophobia
c. Dizziness
d. Ipsilateral “ blurred vision”
e. Difficulties swallowing
f. Ipsilateral oedema, mostly in the periocular area
|
Examination
Subjective
A Headache in occipital or trigeminal nerve distribution
Aggravated by neck movements or prolonged postures
Neck, shoulder or arm pain
Non throbbing
Traumatic or insidious onset
Objective
Abnormal cervical posture
Altered and painful cervical movements- usually extension and ipsilateral rotation
Restricted upper cervical movements, usually ipsilateral rotation
Pain on sustained postures, usually protraction
Pain on palpation sub occipital soft tissue
Special Test
Cervical Flexion-Rotation Test
Further Investigation
Diagnosis usually made clinically
Imaging used to investigate/exclude more serious pathology
Blood work used to exclude other pathology
Zygapophyseal joint, cervical nerve or medial branch blockage
Management
Conservative
Ergonomic advise
Reduce pain and decrease inflammation
Medication, ice and/or heat, massage
Increase range of movement
Reduce tone
Soft tissue techniques, diaphragmatic breathing, stretches, dry needling
Increase articulation of joints of upper cervical spine, particularly flexion and rotation
Soft tissue techniques, stretches, joint mobilisation, manipulation, exercise
Restore Normal Motor Control and Strength
Deep neck flexors, Deep cervical extensors, Scapular stabilisers
Restore Dynamic Stability and proprioception
Surgical
Anaesthetic injections
Spinal nerve, medial branch or facet joint blockade
Radiofrequency thermal neurolysis
Surgical Liberation of occipital nerve
Surgery to underlying pathology (e.g disc pathology)
