The craniocervical junction — where the skull meets the top of the cervical spine — is one of the most mechanically complex and neurologically significant regions of the body. Dysfunction at this junction, sometimes described as craniocervical syndrome, can produce a constellation of symptoms including neck pain, headaches, dizziness, reduced mobility, and postural disturbance.
Dr. Erik Simms evaluates upper cervical function as part of a comprehensive cervical spine assessment. Understanding what is happening at this region — and what conservative care may address — helps patients make informed decisions about their care.
Key Takeaways
- The craniocervical junction involves the skull, atlas (C1), and axis (C2) — a mechanically unique region with significant neurological importance.
- Dysfunction at this junction can contribute to neck pain, headaches, dizziness, and postural disturbance.
- Thorough evaluation — including range of motion, orthopedic testing, and neurological screening — precedes any upper cervical treatment.
- Conservative chiropractic care may support upper cervical function in appropriate cases.
- Symptoms that suggest serious pathology require medical evaluation before chiropractic care proceeds.
What is the craniocervical junction
The craniocervical junction includes the occiput (base of the skull), the atlas (C1), and the axis (C2). This region is structurally distinct from the rest of the cervical spine — it has no intervertebral discs, relies heavily on ligamentous support, and allows the majority of the cervical spine's rotation and nodding movement.
The area is densely innervated and sits in close proximity to the brainstem, the vertebral arteries, and the upper cervical nerve roots. Because of this neurological proximity, dysfunction at the craniocervical junction can produce symptoms that extend well beyond local neck pain.
Symptoms associated with upper cervical dysfunction
- Neck pain and stiffness, often worse with rotation or sustained postures
- Headaches originating at the base of the skull and radiating into the head
- Dizziness or a sense of unsteadiness related to cervical joint receptor input
- Reduced neck range of motion — particularly rotation (looking over the shoulder)
- Facial or jaw discomfort related to upper cervical nerve distribution
- Postural changes — forward head position, asymmetric head tilt, or elevated shoulder
- Difficulty sustaining upright posture for extended periods
Upper Neck Pain, Headaches, or Dizziness?
Dr. Simms conducts a thorough upper cervical evaluation before any treatment is recommended. The examination guides everything — no assumptions, no standard protocols.
Common causes of craniocervical dysfunction
- Prior cervical trauma — motor vehicle accidents, falls, or sports contact that affects the upper cervical ligaments and joints
- Sustained forward head posture from prolonged screen use, common in office workers across Florence, Erlanger, and Covington
- Repetitive postural loading from occupational demands
- Prior cervical surgery or immobilization that alters upper cervical mechanics
- Degenerative changes at C1-C2 that reduce normal movement and alter joint receptor signaling
How Dr. Simms evaluates upper cervical function
- Complete health and symptom history — onset, mechanism of injury, symptom character, and prior treatment.
- Cervical range-of-motion testing — quantifying restriction at all planes with particular attention to C1-C2 rotation.
- Orthopedic provocation testing — specific tests to assess upper cervical joint integrity and reproduce or relieve symptoms.
- Neurological screening — upper extremity reflexes, sensation, and strength when arm symptoms are present.
- Postural assessment — head position, shoulder height, and the relationship between skull position and cervical alignment.
- Review of prior imaging — X-ray and MRI findings reviewed in context; referral for imaging when clinically indicated.
- Vascular history — relevant questions for upper cervical cases given the proximity of the vertebral arteries.
What conservative care may address
When the evaluation supports conservative management, care at the upper cervical region is approached carefully and specifically. Technique selection at C1 and C2 is based on what the examination finds — not on a standard protocol applied to every neck.
- Gentle mobilization of restricted upper cervical joints to restore normal range of motion
- Suboccipital soft tissue release for the muscles that overload in response to upper cervical restriction
- Postural correction addressing the forward head position that drives upper cervical stress
- Corrective exercise to strengthen the deep cervical flexors and upper cervical stabilizers
- Ergonomic guidance for sustained postures that perpetuate upper cervical loading
When upper cervical symptoms require medical evaluation first
- Sudden severe headache unlike any previous headache — requires urgent medical evaluation
- Dizziness accompanied by visual changes, slurred speech, facial drooping, or difficulty walking
- Neck pain after trauma with neurological symptoms in the arms or legs
- Known upper cervical instability from ligamentous injury or connective tissue disorder
- Symptoms that worsen rapidly or do not follow a mechanical pattern
“The upper cervical spine is where we spend the most time on the examination. The joints at C1 and C2 are different from everything below them — and so is the approach to evaluating and treating them.”

Frequently Asked Questions
What is craniocervical syndrome?
Craniocervical syndrome refers to dysfunction at the craniocervical junction — the region where the skull meets the top of the cervical spine (C1 and C2). This dysfunction can produce neck pain, headaches originating at the base of the skull, dizziness, and reduced neck mobility. It is typically mechanical in origin and often follows trauma or develops from sustained postural stress.
Can a chiropractor help with craniocervical dysfunction?
In appropriate cases, chiropractic evaluation and conservative care may help with the mechanical component of upper cervical dysfunction. Dr. Simms conducts a thorough examination — including orthopedic and neurological testing — before recommending any upper cervical treatment. Technique selection is individualized based on examination findings.
What causes upper cervical pain and headaches?
Upper cervical pain and headaches are commonly caused by joint restriction at C1-C2, suboccipital muscle tension from forward head posture, prior cervical trauma (including motor vehicle accidents), and degenerative changes at the craniocervical junction. The upper cervical nerve roots (C1-C3) refer pain patterns into the head that produce headaches that feel indistinguishable from tension or migraine headaches.
What is the difference between cervicogenic dizziness and other types of dizziness?
Cervicogenic dizziness is associated with neck position and movement — it typically worsens with specific head positions or is reproducible with cervical range-of-motion testing. Other types of dizziness (benign positional vertigo, vestibular disorders, vascular causes) have different characteristics. Clinical evaluation, including the Dix-Hallpike test and positional testing, helps distinguish between causes.
Is upper cervical chiropractic care safe?
Upper cervical chiropractic care, when preceded by thorough evaluation including orthopedic, neurological, and relevant vascular screening, has a strong safety record for mechanical upper cervical conditions. Dr. Simms uses the examination findings to determine whether upper cervical treatment is appropriate and which technique is the right approach for each individual patient.
