Clinical synthesis based on the most recent meta-analyses and international consensus statements: ICHD-3, the Demont 2023 PM&R and Martins 2026 meta-analyses, the revisited prevalence of Robinson 2025 Cephalalgia, and the network meta-analyses of Xu & Ling 2025 and Koonalinthip 2026.

How is this condition defined, who does it affect and what are the risk factors?

The headache of cervical origin, or cervicogenic headache (CGH), is classified by the 3rd edition of the International Classification of Headache Disorders (ICHD-3, 2018) under code 11.2.1 as a secondary headache caused by a disorder of the cervical spine and of its bony, discal or tissue components.¹ It is therefore fundamentally distinct from tension-type headache (ICHD-3 chap. 2, primary) and from migraine (chap. 1, primary), even though the clinical presentations may overlap and generate diagnostic errors.¹,

The pathophysiology rests on the anatomical convergence of nociceptive afferents from the C1, C2 and C3 roots and from the trigeminal branch in the trigemino-cervical nucleus caudalis of the brainstem. This convergence explains the referred pain from the neck to the oculo-fronto-temporal regions, demonstrated experimentally by stimulation of the upper cervical structures.²,³ The zygapophyseal joint at C2-C3 is the source most frequently identified by controlled anaesthetic blocks under fluoroscopy; next come C1-C2 (atlanto-axial), the atlanto-occipital joint and the suboccipital muscles.²

Concerning the risk factors 👩‍💻 :

• Cervical trauma, notably whiplash : Sterling 2014 J Physiother documents the frequency of post-traumatic headaches of cervical origin, particularly in whiplash-associated disorders (WAD) of grade II-III.⁴
• Sustained postures (screen work, forward head posture), repeated microtrauma: a factor frequently described in narrative reviews (with no controlled prospective study at a high level of evidence).⁵
• Pre-existing joint dysfunctions of the upper cervical spine, the demonstration of which rests on anaesthetic blocks (Bogduk & Govind 2009).²
• Stress, anxiety, sleep disorders : aggravating factors, and factors of chronicity via central amplification (Castien & De Hertogh 2019 Front Neurol).³

What happens in the body and how does CGH progress naturally?

The pain generally emanates from structures innervated by the C0 to C3 segments. When nociceptive stimulation persists, phenomena of central sensitisation may appear: lowered pain threshold, expansion of the pain field, pericranial allodynia. Castien & De Hertogh 2019 summarise the neurobiology of these changes: modulation of cranio-cervical PPTs (pressure pain thresholds) reflects sensitisation of the trigemino-cervical nucleus, seen in CGH as in migraine and tension-type headache.³

The classic presentation includes:

• Pain most often unilateral without side-shift between attacks: the ICHD-3 specifies that this feature is not specific to CGH and is not among its diagnostic criteria, which rest on evidence of a cervical disorder (criterion B) and on evidence of causality (criterion C).¹
• Cervico-occipital onset, oculo-fronto-temporal radiation.
• The pain is non-pulsatile, dull and deep, of moderate intensity.
• Reproduced by neck movements, sustained postures, or pressure on the neck.
• No aura; mild nausea/photophobia possible but slight (to be differentiated from migraine).

The natural course tends towards chronicity in the absence of targeted management, with fluctuations paced by mechanical exposures.³,⁵ Long-term data remain fragmentary: prospective studies at 5-10 years in untreated cohorts are rare, which limits precise quantification of spontaneous remission rates.

The diagnosis of CGH is clinical : there is no biological marker or reference diagnostic imaging. The ICHD-3 (2018) requires evidence of a cervical disorder as the cause of the headache, with a temporal relationship and improvement in parallel with resolution of the disorder.¹ The Rubio-Ochoa 2016 Manual Therapy meta-analysis confirms that no single test is sufficient: it is the convergence of a compatible history, reduced mobility and pain reproduced by segmental palpation that makes up the strongest diagnostic cluster.²

Which questions should you ask to understand the patient and their history?

🎯 The history should explore five key dimensions:

• Laterality : “Is the pain always on the same side?” A unilaterality without side-shift is frequent in CGH, but the ICHD-3 reminds us that it is not specific to it (a migraine can stay on the same side) and that its absence does not exclude the diagnosis.¹
• Cervical mechanics : “Do your neck movements or certain postures (prolonged screen use, driving, pillow) trigger the headache?” A positive answer is highly suggestive.³
• Pain character : non-pulsatile, deep, dull; moderate intensity, unlike migraine (pulsatile, severe) and tension-type headache (mild, bilateral, vice-like).¹
• Associated symptoms : mild nausea, ipsilateral blurred vision possible; no aura (vs migraine).¹
• History of trauma : whiplash, cranio-cervical trauma, contact sport, a very frequent factor (Sterling 2014).⁴

Which clinical tests should you perform and which other conditions should you rule out?

The physical examination must objectively document the cervical findings.

• Assessment of active and passive cervical ranges of motion to look for a segmental and global restriction, as recommended by the JOSPT guidelines (Blanpied 2017).⁵
• Cervical flexion-rotation test (CFRT) ⭐: patient supine, the examiner performs maximal upper cervical flexion then passive rotation to each side. Test positive if rotation < 32° or side-to-side difference > 10°. Ogince 2007 and Hall 2010 reported a sensitivity of 86-91% and a specificity of 90-100% in small samples;⁶,⁷ the 2022 meta-analysis (4 studies, 182 participants, moderate certainty) gives 83% for both (LR+ 5.0; LR− 0.2): a positive or negative test changes the probability of CGH by a small to moderate amount.¹³ The Rubio-Ochoa 2016 SR confirms the diagnostic value of the CFRT and of deep flexor strength in differentiating CGH vs migraine.²
• Segmental palpation C0-C1, C1-C2, C2-C3 : sustained pressure seeking to reproduce the familiar pain of the patient, a major ICHD-3 criterion.¹,³
• Deep cervical flexor test (Cranio-Cervical Flexion Test, CCFT) : documents the failure of deep motor control, common in CGH patients (Jull 2002).⁸

Differential diagnosis 🤔: systematically rule out primary headaches (migraine, tension-type headache) and other secondary headaches (Arnold's neuralgia, vertebral dissection, subarachnoid haemorrhage).

Before any cervical technique (mobilisation, traction, manipulation, exercise included), the IFOMPT cervical framework (JOSPT 2023) calls for explicit vascular reasoning: history of cardiovascular risk factors and of whether the headache or neck pain is recent or unusual, blood pressure, cranial nerve examination and neurological examination when the history suggests it, then informed consent; pre-manipulative positional tests are no longer recommended by the framework.¹⁴ This reasoning documents the decision without guaranteeing it: the only accuracy measurement available, the Go4Safe study, concerns the earlier version of the framework; against an expert decision supported by imaging, that version showed a sensitivity of 0.50 and a specificity of 0.63, and the accuracy of the 2023 framework has not been evaluated. A negative screen therefore does not rule out vascular risk, and monitoring of symptoms remains appropriate during and after the session.¹⁵

Should patients with CGH be classified, and for what benefit?

The mechanistic sub-classification makes it possible to individualise treatment ✅. Three main clinical subtypes emerge from the literature:

1. Dominant joint dysfunction (segmental hypomobility at C1-C2 or C2-C3) benefits primarily from targeted mobilisations/manipulations (Núñez-Cabaleiro 2022).⁹
2. Cervical motor control dysfunction (weakness of the deep flexors, overactivity of the superficial ones) calls primarily for Jull's exercises (CCFT).⁸
3. Predominant central sensitisation (diffuse hypersensitivity, allodynia, psychosocial comorbidity) calls for pain education + biopsychosocial management (Castien & De Hertogh 2019).¹⁰

This stratification is a matter of clinical reasoning: matching the modality to the dominant mechanism has not been tested as such in the meta-analyses (Demont 2023 PM&R,¹¹ Martins 2026).

Evidence-based management of CGH has converged since 2022-2025 towards an approach that is multimodal, combining targeted manual therapy and active exercises, all underpinned by solid therapeutic education.¹,² Isolated data suggest a benefit of this combination,²,³ but its contribution compared with each modality alone remains uncertain in the 2026 meta-analysis.¹³

Where do you start? What is the recommended hierarchy of interventions?

The recommended pragmatic sequence is:

1. 🧠 Education and reassurance : explain the benign but persistent nature of CGH, the mechanism of referred pain and the patient's active role. Pain neuroscience education (PNE) improves outcomes in chronic musculoskeletal pain (Louw 2011 APMR).⁴
2. 🤲 Targeted manual therapy on the C1-C2/C2-C3 segments: mobilisations, Mulligan SNAGs, upper cervical manipulations, each preceded by the vascular reasoning of the IFOMPT framework (chapter 2). Against sham, short-term effect on headache (Demont 2023, moderate certainty; Martins 2026, large but of low certainty), with no difference at 12 months;¹,¹³ Bini 2022 (Chiropr Man Therap) and Núñez-Cabaleiro 2022 (Headache) describe an effect that may be maintained in the long term.⁵,⁶
3. 💪 Active exercises : cranio-cervical flexion + deep flexor endurance + scapular stabilisers (Jull 2002 Spine RCT 200 patients).⁷
4. 🧩 Addressing psychosocial factors and self-management strategies for durability.

What place does exercise hold and is there a superior approach?

The pivotal Jull 2002 Spine trial (n = 200 CGH patients, 12-month follow-up) remains the reference: the low-load exercise programme (cranio-cervical flexion in supine with pressure biofeedback) combined with manual therapy is significantly superior to control, with the effects maintained at 12 months.⁷ The benefits accumulate without being strictly additive (combination +10% responders vs each modality alone).⁷

The meta-analysis Demont 2023 ranks the exercise approaches in the following order: multimodal exercise + manual therapy > cervical motor control alone > stretching alone (small effect) > no exercise.¹ The more recent SR on therapeutic exercise (Becher 2023 MSP, 11 studies) finds, for multimodal exercise against controls, a large effect on headache frequency (SMD 0.98) and on headache intensity (SMD 0.73), with low to very low quality of evidence.²

Recommended exercise programme 💪 :

• Cranio-Cervical Flexion Test (CCFT) : subtle head nod in supine, pressure biofeedback. 10 repetitions, progressing through the 22-30 mmHg levels.
• Deep flexor endurance : isometric hold 10 s × 10 repetitions, twice a day.
• Scapular stabilisers : lower trapezius (Y/T rows), serratus anterior (push-up plus).
• Upper thoracic mobility : extensions seated or on all fours to offload the cervical compensations.
• Endurance > maximal strength : the ability to sustain prolonged postural activation is the main lever (Jull 2002).⁷

Manual therapies, dry needling: how effective are they really?

The NMA Xu & Ling 2025 (Frontiers Neurology, 14 trials, 1,297 patients) finds the Mulligan SNAGs applied at C1-C2/C2-C3 superior to non-SNAG interventions in direct comparison; in the network, it ranks cervical manipulation first for short-term pain, stressing the role of clinician expertise.⁸ Two other network meta-analyses (Jung 2024, 23 trials; Koonalinthip 2026, 41 trials) place combinations that include dry needling first in the short term. Jung rates the certainty as low and makes no firm recommendation;¹⁴ Koonalinthip concludes that multimodal non-pharmacological approaches do better, in the short term, than single-modality approaches,¹² whereas Martins 2026 judges the added benefit of combinations uncertain.¹³ No technique is the clear choice. Upper cervical manipulations (HVLA) remain an option (Núñez-Cabaleiro 2022),⁶ preceded, like any cervical technique, by the vascular reasoning of the IFOMPT framework (chapter 2).

The dry needling of myofascial trigger points of the upper trapezius, suboccipitals and sternocleidomastoid is an adjunct option. The Pourahmadi 2021 Physical Therapy meta-analysis (on CGH/TTH/migraine combined) finds a significant reduction in headache intensity and frequency, but with moderate quality of evidence and high heterogeneity.⁹

The levels in this table are an editorial judgement applying GRADE principles, and not a published GRADE assessment.

How do you educate the patient and address psychological factors?

Pain neuroscience education (PNE) has shown its value in chronic musculoskeletal pain (Louw 2011 APMR): reduced perception of threat, less kinesiophobia, improved active engagement.⁴ This approach combines with ergonomic advice (postural variability rather than a “perfect posture”) and stress management strategies (diaphragmatic breathing, mindfulness).

The yellow flags (catastrophising, fear of movement, erroneous beliefs) are predictors of chronicity. The “Decade of the Flags” (Nicholas 2011 Phys Ther) proposed an operational framework for their early identification and management.¹⁰

The transition between symptom relief and long-term recovery is the main clinical challenge. The convergent literature (Demont 2023; Bini 2022) places self-management and home exercise maintenance at the centre of the care plan.¹,²

How do you make the patient an active player in their own recovery through self-management?

🧘 Self-management rests on 4 pillars:

• Therapeutic education starting with a solid base: the nature of CGH, the neuroanatomical mechanism, the role of postures and stress, reasonable expectations (gradual, not immediate, recovery).³
• Home exercise programme (HEP) short and personalised: 2-3 key exercises (CCFT, deep flexor isometrics, scapular stabilisers) with clear instructions (photos/videos). Long-term adherence remains the major prognostic factor.²,⁴
• Realistic ergonomics : aim for postural variability (changes of position every 30-45 min, brief stretches) rather than a rigid “perfect posture”.⁵
• Stress management and sleep : diaphragmatic breathing, mindfulness, sleep hygiene. Reduces sympathetic activation and cervical muscle tension.⁶

When and how do you plan a safe return to sport and to activity?

🏃‍♀️ The return to sport should be gradual and guided by symptoms. There is no universal timetable: a stepwise protocol (24-48 h between stages) is the norm adapted from whiplash and post-concussion protocols:⁷,⁸

1. Activities of daily living without significant pain.
2. Light aerobic exercise (brisk walking, stationary cycling, 30 min). Check cardiovascular tolerance without triggering headache.
3. Sport-specific exercises without impact (drills, shadow strikes).
4. Strengthening and dynamic exercise progressively increased, with symptom monitoring.
5. Full training without contact.
6. Return to competition.

Golden rule : any reappearance of the familiar headache at a stage requires going back to the previous non-symptomatic stage for 24-48 h, before a new attempt at progression.⁷

Case reports represent a low level of evidence (Oxford CEBM 5) but have didactic value for illustrating clinical reasoning in real-life conditions. 🧠

Analysis of a “classic” case: from assessment to resolution

The case report Lewis & Naude 2010 SAJP describes a 26-year-old man with cervicogenic headache associated with a concomitant temporomandibular dysfunction.¹ The assessment identified an upper cervical segmental restriction (positive CFRT), weakness of the deep flexors and limited TMJ mobility.

Multimodal treatment plan (9 sessions):

• Maitland mobilisations of the upper cervical spine and TMJ.
• Trigger point therapy / massage of the suboccipitals and upper trapezius.
• Progressive strengthening of the deep flexors and scapular stabilisers.
• Postural correction, education on triggers.

Result : improvement on all outcome measures, cervical and TMJ range of motion restored, headache intensity and frequency significantly reduced by the 9th session.¹

The diagnostic challenge: when CGH mimics another condition

The case report Satpute 2020 JMMT (PMID 31537198) illustrates the complexity of the differential diagnosis in a patient with mixed features of migraine + CGH.² An approach known as headache symptom modification : segmental palpation and certain manual therapy techniques reproduce the patient's familiar pain (a sign of cervical origin), then its rapid resolution after mobilisation (a sign of effectiveness).

The clinical benefit: shortening the decade of diagnostic wandering often seen in patients labelled “chronic migraine” but whose cervical component was never properly assessed.² A rigorous cervical examination according to ICHD-3 in every patient with chronic unilateral headaches remains under-used in routine practice.

Study of a complex case (post-concussion + CGH)

🧩 Post-concussion cases with a cervical component are frequent. The Amsterdam 2022 international consensus on concussion (Patricios 2023 BJSM) recommends systematic cervical assessment in persistent post-traumatic headaches.³ Integrated approach:

• Manual therapy that is gentle and applied to the upper cervical spine (grade I-II mobilisations), without manipulation as long as central sensitisation persists.
• Vestibular and oculomotor rehabilitation if associated dizziness/instability.
• Progressive cervical motor control exercises.
• Progressive reintroduction of sub-symptomatic aerobic activity.

When and to which other health professionals should you refer?

🧐 Recognising situations that fall outside the scope of physiotherapy is essential.

• 🚩 Red flags : thunderclap headache, progressive neurological deficit, fever + neck stiffness, unexplained weight loss, history of cancer, recent cervical trauma. The Finucane 2020 JOSPT framework recommends analysing flags as a cluster rather than trusting a single flag, because the predictive value of each flag taken alone is low.¹ → urgent medical referral.
• 🟡 Yellow flags (catastrophising, kinesiophobia, anxiety): Nicholas 2011 Phys Ther proposes the operational framework.² → collaboration with a psychologist / the treating physician.
• 🔵 Blue flags (work-related conflict/tension) → collaboration with occupational medicine.

How do you measure outcomes and overcome barriers to implementation?

📈 Standardised outcome measurement is indispensable for objectively demonstrating effectiveness and adapting management.

Recommended PROMs for CGH :

• NPRS (Numeric Pain Rating Scale) 0-10: usual pain and worst pain.
• NDI (Neck Disability Index) : cervical disability, validated in French, MCID ≈ 7 points.
• HIT-6 (Headache Impact Test) : functional impact of headaches, validated in several languages.
• MIDAS (Migraine Disability Assessment) : frequency and impact over the preceding 3 months.
• PSFS (Patient-Specific Functional Scale) : individualised functional goals.

Classic barriers to implementation :

• Lack of time during consultations.
• Difficulty of access to, and critical reading of, the literature.
• Lack of organisational support.
• Clinical inertia (preference for habits).

Multi-faceted strategies to overcome them: targeted continuing education, mentoring by EBP champions, integration of PROMs into the practice software, explicit shared decision-making with the patient. The JOSPT 2017 Blanpied guidelines recommend these combined approaches for neck pain in general (and therefore applicable to CGH).³
