The Neck Injury You Didn't Know You Had The cervicogenic component of concussion refers to the simultaneous neck injury that occurs with virtually every concussion. The same forces that shake your brain also strain your cervical spine: muscles, ligaments, facet joints, and neural structures. These cervical injuries produce headaches, dizziness, visual disturbances, and cognitive fog that are clinically indistinguishable from concussion symptoms (Ellis et al., 2015). This matters because cervical dysfunction does not resolve with brain rest. You can wait weeks or months for "concussion recovery" while the actual symptom driver (your neck) goes untreated. Studies estimate that cervical pathology contributes to symptoms in 25-50% of patients diagnosed with persistent post-concussion syndrome. Identifying and treating the cervicogenic component is one of the most effective interventions for patients whose concussion recovery has stalled. Why the Neck Always Gets Injured Biomechanical coupling. Your head weighs 10-12 pounds and sits on a narrow, flexible cervical spine. Any force sufficient to cause concussion (acceleration/deceleration of the brain within the skull) simultaneously accelerates the head relative to the neck. The cervical spine absorbs these forces through muscle strain, ligament sprain, and facet joint compression. Whiplash mechanism. Most concussions involve rapid acceleration-deceleration (vehicle collisions, sports impacts, falls). This is the same mechanism that causes whiplash. Concussion and whiplash are not separate injuries. They are different manifestations of the same mechanical event affecting different structures (Hynes & Bhatt, 2020). Rotational forces. Rotational impacts (the most common concussion mechanism) create torsional strain on cervical structures. Upper cervical joints (C0-C2) are particularly vulnerable because they allow the greatest rotational range. Injury to these joints produces symptoms that precisely mimic concussion. Symptoms From the Cervicogenic Component Cervicogenic headache. Headache originating from cervical structures (facet joints, muscles, upper cervical nerves) accounts for a significant proportion of post-concussion headaches. These headaches typically start at the base of the skull and radiate forward. They worsen with sustained postures and cervical movement. They respond to cervical treatment, not brain rest. Cervicogenic dizziness. The upper cervical spine contains dense proprioceptive receptors that provide head position information to vestibular centers. Cervical dysfunction sends inaccurate position data, creating a sensory mismatch perceived as dizziness. This dizziness is movement-related and position-dependent, often provoked by head turning. Visual disturbance. Cervical proprioceptive dysfunction affects the cervico-ocular reflex, which helps stabilize vision during head movement. Impaired cervical input produces blurred vision, difficulty tracking, and visual motion sensitivity that resemble vestibular or oculomotor concussion symptoms. Cognitive fog. Cervicogenic headache and pain produce attentional interference. Constant pain input consumes cognitive bandwidth, reducing available processing capacity. This manifests as difficulty concentrating and mental fatigue that appears cognitive but is actually pain-driven. Neck pain and stiffness. The most obvious cervical symptom, but often dismissed as "expected after head injury." Persistent neck pain indicates structural dysfunction that produces the referred symptoms listed above. Cervical Mobility for the Cervicogenic Component These exercises directly address cervical dysfunction: JME 1 Cervical rotation restores rotational range of motion in the upper cervical spine where concussion-related restrictions develop. JME 14 Chin tucks strengthen deep cervical flexors and correct the forward head posture that perpetuates cervicogenic symptoms. JME 3 Lateral flexion addresses side-bending restrictions that contribute to cervicogenic headache patterns. JME 35 Cervical stabilization builds the deep muscle endurance needed for sustained symptom-free cervical function. Start your 14-day free trial for targeted cervical mobility programming. Shoulder and Upper Back Support JME 22 Neck mobility work maintains the cervical range of motion needed for daily function without symptom provocation. JME 42 Shoulder mobility reduces upper trapezius tension that refers pain to the cervical spine and head. JME 153 Upper back mobility prevents the thoracic stiffness that overloads cervical structures. JME 164 Scapular mobility maintains shoulder blade positioning that supports optimal cervical spine mechanics. Identifying the Cervicogenic Component Physical examination findings. A physiotherapist or manual therapist trained in cervical assessment identifies specific findings: restricted cervical range of motion, reproduction of headache with palpation of upper cervical joints, positive cervical flexion-rotation test (restricted C1-C2 rotation), and painful muscle trigger points in suboccipital, upper trapezius, and sternocleidomastoid muscles. Symptom behavior clues. Cervicogenic symptoms are position-dependent and movement-related. If headache worsens with sustained postures (computer work, reading), improves with position changes, and is triggered by neck movements, cervical origin is likely. Brain-origin concussion headache is more constant and exertion-related. Response to cervical treatment. The most definitive test is treatment response. If cervical manual therapy and targeted exercises reduce headache, dizziness, and cognitive symptoms, the cervicogenic contribution is confirmed. This therapeutic trial approach is both diagnostic and treatment. Treatment of the Cervicogenic Component Manual therapy. Specific joint mobilization of restricted cervical segments, particularly upper cervical (C0-C2) and mid-cervical facet joints. Soft tissue treatment for suboccipital muscles, upper trapezius, sternocleidomastoid, and scalenes. Typically 4-8 sessions over 3-6 weeks produce significant improvement. Cervical exercise program. Deep cervical flexor strengthening (chin tucks with progressive hold times), cervical proprioceptive retraining (head repositioning accuracy exercises), and graduated cervical range of motion restoration. Daily home exercises complement manual therapy sessions. Postural correction. Forward head posture increases cervical loading by 10 pounds for every inch of forward displacement. Correcting workplace ergonomics, screen heights, and habitual postures reduces the mechanical load perpetuating cervicogenic symptoms. Integration with concussion management. Cervical treatment doesn't replace brain-directed concussion management. It complements it. Patients often need concurrent aerobic exercise prescription (for autonomic recovery) and cervical therapy (for cervicogenic symptoms). Addressing both simultaneously produces faster overall recovery than sequential treatment. Address your cervical component with simplmobility's targeted neck mobility routines. How common is neck injury with concussion? Virtually universal. The same forces causing concussion strain the cervical spine. The question is not whether cervical injury occurred, but whether it's contributing meaningfully to persistent symptoms. Clinical assessment determines the degree of cervicogenic contribution for each patient. Do I need imaging for the cervicogenic component? Standard X-rays and MRI often appear normal in cervicogenic dysfunction because the pathology involves joint mobility, muscle function, and neural sensitivity rather than structural damage visible on imaging. Clinical assessment by a skilled manual therapist identifies cervicogenic dysfunction more reliably than imaging studies. How quickly does cervical treatment improve concussion symptoms? Many patients notice headache reduction within 2-3 manual therapy sessions (1-2 weeks). Dizziness improvement follows within 2-4 weeks. Full cervicogenic symptom resolution typically occurs within 4-8 weeks of consistent treatment and home exercise. Some patients experience dramatic improvement after the first treatment session. Should I see a physiotherapist or chiropractor for the cervicogenic component? Either profession can effectively treat cervicogenic dysfunction, provided the practitioner has specific training in concussion management and cervical assessment. Look for practitioners with sports medicine or concussion-specific credentials. The specific clinical skills matter more than the professional title. References Ellis, M. J., et al. (2015).
