Migraines and Chiropractic Care: Unraveling the Connection

Google+ Pinterest LinkedIn Tumblr +

Migraines are a complex neurological condition that are more than simply severe headaches. They’re characterized by episodes of head pain, often severe and debilitating, often accompanied by other symptoms such as nausea, vomiting, and extreme sensitivity to light and sound. Migraines are typically characterized by their pulsating or throbbing nature, usually occurring on one side of the head and lasting from hours to days. The World Health Organization ranks migraines among the top 20 most disabling medical illnesses worldwide, making it crucial to find effective treatments.

Chiropractic care is a health profession that emphasizes diagnosis, treatment, and prevention of mechanical disorders of the musculoskeletal system, especially the spine. As chiropractors, we focus on the intimate relationship between the nervous system and spine, recognizing the potential for significant health impacts. This article seeks to explore the potential connection between migraines and chiropractic care, the mechanisms of chiropractic interventions, and how they may help those who suffer from migraines.

Migraine Pathophysiology

Migraine pathophysiology is multifaceted and not fully understood. Nevertheless, it is commonly agreed upon that migraines involve hyperexcitable brain states leading to an imbalance between excitatory and inhibitory stimuli. During a migraine attack, a wave of electrical activity spreads across the brain, followed by a period of reduced activity. This wave, also known as cortical spreading depression (CSD), triggers a series of neurochemical processes leading to the release of inflammatory substances, which subsequently cause vascular changes and activate pain pathways.

The Role of the Cervical Spine and Nervous System

A growing body of evidence indicates that dysfunction in the cervical spine, particularly the upper cervical spine, might play a significant role in the onset and development of migraines. Misalignment or subluxations in the cervical spine can irritate or compress nerves, leading to neural inflammation and potentially triggering migraines. Moreover, the trigeminocervical nucleus, a region in the brainstem where the trigeminal and upper cervical nerves converge, has been identified as a critical area in the pathophysiology of migraines.

Chiropractic Approaches to Migraine Management

The primary chiropractic approach to migraine management is through spinal manipulation, particularly in the cervical region. Spinal manipulation, commonly referred to as a chiropractic adjustment, involves applying a controlled, sudden force to a spinal joint. The goal of these adjustments is to correct subluxations, restore optimal nervous system function, and improve spinal biomechanics. In turn, this may decrease neural irritation and inflammation, reducing the frequency and intensity of migraines.

Evidence for Chiropractic Care in Migraine Management

Several studies have evaluated the effectiveness of chiropractic care for migraine management, and many of them have reported promising results. A randomized controlled trial by Tuchin et al. found that over half of the participants experienced a significant reduction in the frequency of their migraines after two months of chiropractic treatment.

A 2016 review of the literature in the European Journal of Neurology concluded that chiropractic spinal manipulative therapy appears to be effective in the treatment of migraines. The authors suggested that it might be considered a treatment option for patients who prefer not to take medication or for those who experience adverse effects from medication.

These studies, among others, suggest a potential beneficial role for chiropractic care in the management of migraines, although further high-quality studies are required to establish more conclusive evidence.

Mechanisms of Action

The exact mechanisms of action through which chiropractic care exerts its effects on migraines remain uncertain. However, several theories have been proposed.

Firstly, spinal adjustments could potentially reduce peripheral nerve irritation and inflammation, thereby disrupting the nociceptive inputs to the trigeminocervical nucleus, which could in turn decrease the frequency and severity of migraines.

Secondly, spinal manipulative therapy may also lead to changes in certain neurological pathways, influencing pain modulation and perception.

Finally, chiropractic care may exert its benefits through improving overall biomechanics and posture. Poor posture, particularly forward head posture, can lead to increased muscle tension and strain, which could potentially contribute to migraines. By correcting posture and optimizing spinal alignment, chiropractic care may decrease muscle tension and reduce migraine occurrence.

Clinical Considerations

In clinical practice, each migraine sufferer’s presentation will be unique, necessitating an individualized approach to care. Careful assessment and history taking are essential to identify potential triggers and underlying contributing factors. A comprehensive musculoskeletal examination, including a detailed evaluation of the cervical spine, is necessary.

The treatment plan will often include spinal manipulative therapy targeting identified subluxations. Moreover, the management plan may also involve addressing lifestyle factors such as stress management, dietary considerations, and exercise prescription, as these can significantly impact migraine occurrence and severity.

Chiropractors should also be mindful of when a referral is appropriate. While many migraine sufferers may benefit from chiropractic care, cases with unusual or worrying features, such as sudden onset of severe headache, changes in pattern or frequency of headaches, or associated neurological symptoms, should be referred for further investigation.


While the relationship between migraines and chiropractic care is complex and not entirely understood, existing research suggests a potential beneficial role for chiropractic interventions in the management of migraines. The intimate relationship between the spine and nervous system, coupled with the potential involvement of cervical spine dysfunction in migraine pathophysiology, provides a plausible rationale for the efficacy of chiropractic care.

As chiropractors, our holistic approach to healthcare and focus on individualized care put us in a unique position to potentially help many who suffer from migraines. Nevertheless, further high-quality research is required to further elucidate the exact mechanisms of action and optimize treatment protocols. Until then, we continue to offer evidence-informed care and strive for the best possible outcomes for our patients.
