How Chiropractic Care Influences Brain-Body Communication: The Research of Dr. Heidi Haavik

Posted: October 30th, 2026

Key Takeaways

• Brain-Body Connection: Research led by Dr. Heidi Haavik shows that spinal function influences how the brain processes sensory signals.

• Sensorimotor Integration: Spinal adjustments help improve how the central nervous system interprets movement and coordinates muscular response.

• Advanced Neuroimaging: Studies using EEGs show measurable shifts in central nervous system activity, brain network processing, and reflex regulation.

Introduction: Modern Science and the Brain-Body Link

For years, chiropractic care was viewed primarily through the lens of spinal alignment and joint movement. However, ongoing neuroscientific research—led by Dr. Heidi Haavik and her international collaborative research team—demonstrates that gentle spinal adjustments directly influence central nervous system function.

1. How the Spine Acts as a Primary Sensory Organ

Deep paraspinal muscles in the spine contain high concentrations of sensory receptors called muscle spindles. These receptors constantly send feedback to the brain regarding body position and posture (proprioception).

• Subclinical Spinal Dysfunction: When joints in the spine move suboptimally, sensory input to the brain can become distorted.

• Clearer Signals: Correcting movement dysfunction allows accurate sensory data to reach the brain, supporting clear brain-body communication.

2. Sensorimotor Integration and Motor Control

Research shows that precise spinal adjustments alter how the prefrontal cortex processes incoming information:

• Reflexes & Balance: Studies demonstrate changes in H-reflexes and limb motor control following spinal manipulation.

• Reaction Time & Coordination: Improved sensorimotor integration helps the brain execute accurate physical movements and maintain balance.

3. Cutting-Edge Brain Dynamics (EEG Research)

Collaborative studies using source-localised EEG have explored how spinal adjustments affect central nervous system activity:

• Triple-Network Dynamics: Studies show frequency-specific changes across key neural networks (Salience, Default Mode, and Central Executive Networks).

• Calm Central Processing: Research indicates post-adjustment shifts in brainwave activity (such as increased alpha and beta activity), supporting regulated autonomic response.

4. Collaborative Studies and Emerging Insights

Haavik's collaborative trials continue to explore broader physiological associations across various populations:

• Neurological Function & Motor Recovery: Investigating brain plasticity and motor outputs in populations recovering from stroke or experiencing mild cognitive changes.

• Biometric Monitoring: Utilizing objective tools (e.g., somatosensory evoked potentials and biometric tracking) to measure nervous system adaptations.

What This Means for Patients

Chiropractic care focuses on supporting optimal spinal function and nervous system communication. By addressing mechanical dysfunction in the spine, care helps support the brain's natural ability to receive accurate body signals.

Frequently Asked Questions

What does the research say about chiropractic care and the brain?

Research led by neurophysiologist Dr. Heidi Haavik and international research teams suggests that chiropractic adjustments can influence how the brain receives and processes sensory signals from the spine—a process known as sensorimotor integration. Objective neurofunctional measurements, such as EEG studies, observe shifts in central brain processing and motor control following spinal manipulation.

Does chiropractic care treat neurological conditions like stroke or dementia?

No. Chiropractic care in the UK is regulated by the General Chiropractic Council (GCC) for the management of musculoskeletal conditions, including back pain, neck strain, cervicogenic headaches, and joint stiffness. Laboratory research on brain network changes describes potential neurophysiological mechanisms under study; it does not constitute a claim that chiropractic care treats, prevents, or cures organic neurological disorders.

How does this research apply to patients visiting Falcon Chiropractic in Harrogate?

While scientific studies focus on understanding underlying neurophysiological mechanisms, in clinic, our registered chiropractors—Dr. Jessica Falconer, DC and Dr. Tom Blayney, DC—use these insights to inform our approach to joint function, movement mechanics, and posture. Improving joint mobility helps support clear sensory feedback to the central nervous system as part of a rounded, personalized care plan.
