Same Mechanism, Two Injuries You do not get a concussion without also getting a whiplash injury. The forces required to accelerate the brain inside the skull are the same forces that strain cervical spine structures. The head weighs 10-12 pounds and sits on the narrow cervical spine. When the head is accelerated rapidly (impact, fall, collision), the brain moves inside the skull (concussion) and the cervical structures are stretched beyond their normal range (whiplash). These are not two separate events. They are one mechanism producing two injuries simultaneously. Up to 75% of patients with persistent post-concussion symptoms have identifiable cervical spine dysfunction (Kennedy et al., 2017). This statistic reveals the core problem in concussion management: the cervical component is consistently underdiagnosed and undertreated. Patients are told they have a concussion and treated for a brain injury while the neck injury producing identical symptoms goes unaddressed. Why Cervical Symptoms Mimic Concussion Cervicogenic headache. The upper cervical spine (C0-C3) refers pain to the head through the trigeminocervical nucleus. This produces headache patterns indistinguishable from concussion headache: pain at the base of the skull, behind the eyes, across the forehead, or throughout the entire head. Without cervical assessment, this headache is attributed to the brain injury. Cervicogenic dizziness. The cervical spine contains dense proprioceptive receptors that provide the brain with head-position information. Whiplash injury disrupts these receptors, producing inaccurate position signals that create dizziness, unsteadiness, and spatial disorientation. This dizziness feels identical to vestibular dizziness from brain injury but requires different treatment (Treleaven, 2008). Cognitive fog from cervical dysfunction. Impaired cervical proprioception forces the brain to allocate extra processing resources to maintain head position and balance. This diverts cognitive resources from other tasks, producing the concentration difficulty and mental fatigue attributed to concussion. Treating the cervical proprioceptive impairment frees these resources and cognitive function improves. Nausea and visual disturbance. Cervical proprioceptive mismatch between neck position signals and vestibular/visual signals produces nausea and visual disturbance. The brain receives conflicting information about head position, creating sensory conflict symptoms identical to those produced by vestibular concussion injury. How to Tell if Your Symptoms Are Cervical Symptoms that change with neck position. If headache, dizziness, or visual disturbance worsen when you turn your head, look up, or hold your neck in certain positions, the cervical spine is contributing. Brain-based concussion symptoms do not change with neck position. Neck pain or stiffness. While neck pain alone does not confirm cervicogenic symptoms, its presence alongside headache and dizziness increases the probability of cervical involvement. Many concussion patients dismiss neck symptoms as "secondary" when they are actually the primary symptom driver. Symptoms that improve with cervical treatment. The most definitive indicator: if manual therapy to the cervical spine or targeted cervical exercises produce immediate improvement in headache, dizziness, or cognitive function, the cervical spine is a significant contributor. Symptoms persisting beyond 2-4 weeks. By 2-4 weeks, the brain's metabolic injury has resolved in most cases. Symptoms persisting beyond this window are more likely cervical than brain-based. This is why cervical assessment is critical for anyone with prolonged concussion recovery. Cervical Treatment for Whiplash-Concussion Cervical mobility exercises address the musculoskeletal component that contributes to "concussion" symptoms: JME 1 Cervical rotation is the most commonly restricted movement after whiplash-concussion. Rotation restriction directly correlates with cervicogenic headache severity. Restoring full, symmetric rotation is the priority intervention. JME 14 Deep cervical flexor retraining. These muscles are consistently impaired after whiplash. Their weakness produces poor head-on-neck stability, increased cervicogenic dizziness, and headache. Restoring these muscles is foundational to cervical concussion recovery. JME 23 Upper cervical mobility targets the C0-C2 segments where cervicogenic headache originates. Restriction at these levels is the most common finding in whiplash-concussion patients with persistent headache. JME 5 Cervical extension mobilizes the suboccipital region. The whiplash mechanism strains the posterior cervical structures, producing restriction that contributes to headache and dizziness when looking up.

Complete Whiplash-Concussion Recovery Program JME 3 Lateral cervical flexion releases the upper trapezius and scalene muscles that spasm during whiplash. This muscular guarding restricts cervical mobility and contributes to tension-type headache. JME 150 Thoracic rotation ensures the mid-back contributes appropriately to rotational movement. When the thoracic spine is stiff (common after whiplash), the cervical spine bears excessive rotational demand. JME 42 Shoulder mobility breaks the tension chain from shoulders through upper trapezius to the base of the skull. Whiplash produces protective shoulder elevation that perpetuates cervical symptoms. JME 153 Thoracic extension counteracts the forward, protective posture that develops after whiplash. Restoring thoracic extension improves breathing mechanics and reduces cervical compensatory strain. Address both injuries with simplmobility's comprehensive recovery programming. Treatment Approach: Treat Both Injuries The brain and neck need simultaneous treatment. The outdated model treats concussion first (rest, wait for brain healing) then addresses the neck "if symptoms persist." The current evidence supports treating both from day 1. Cervical treatment started early produces faster overall recovery because it eliminates the cervical symptom contribution immediately rather than waiting until the brain has healed to discover the neck is the remaining problem. Physiotherapy with cervical expertise is essential. A physiotherapist trained in both concussion and cervical spine assessment provides the most comprehensive initial evaluation. They differentiate brain-based symptoms from cervical symptoms and treat the cervical component while monitoring concussion recovery. Manual therapy accelerates cervical recovery. Skilled manual therapy to the upper cervical spine combined with specific exercises produces faster improvement than exercises alone. Manual therapy addresses joint restrictions that exercises alone take longer to resolve. Does every concussion involve whiplash? Functionally, yes. Any force sufficient to cause concussion also produces cervical strain. The severity of the cervical injury varies. Some patients have significant cervical dysfunction driving their symptoms. Others have mild cervical involvement that resolves quickly. The point is that cervical assessment should be standard in every concussion evaluation, not an afterthought when symptoms persist. Is my headache from my brain or my neck? Often both, especially in the first 2 weeks. As the brain heals (typically by 2-4 weeks), headache that persists is increasingly likely cervicogenic. A skilled clinician differentiates these by assessing cervical range of motion, palpating cervical structures, and performing provocation tests that reproduce or relieve the headache through cervical movements. Does whiplash require different treatment than concussion? Yes. Brain-based concussion recovery relies on rest, graduated activity, and time. Cervical whiplash recovery requires manual therapy, specific exercises, and progressive loading. The distinction matters because "rest and wait," the standard concussion advice, does not treat cervical dysfunction. Active cervical treatment from early in recovery produces the best outcomes for the combined whiplash-concussion injury. References Kennedy, E., et al. (2017).
