How spinal function connects to cognitive performance
Chiropractic care is traditionally known for improving mobility and reducing pain, but recent neuroscience reveals a deeper connection — how spinal function influences brain function. In particular, studies by Dr Heidi Haavik and colleagues show that adjustments can affect areas of the brain responsible for focus, attention, working memory, and executive control.
What the research explored
Using EEG (electroencephalography) and functional MRI, researchers examined how spinal adjustments alter brain activity in the prefrontal cortex — the region that manages complex thought and decision-making. They tested participants on reaction time, accuracy, and attention-based tasks before and after adjustments to observe potential performance changes.
Key findings
- Adjustments produced measurable changes in prefrontal cortical activity, suggesting improved neural efficiency and information processing.
- Participants often showed improved reaction speed and task accuracy immediately following care.
- Enhanced activation in attention and executive control networks was observed on EEG and fMRI scans.
- Researchers propose that improved sensory feedback from the spine enhances brain-body communication, indirectly benefiting cognition.
Clinical significance
Improved neural efficiency doesn’t just affect movement — it can also enhance mental performance. Patients often describe feeling “clearer,” “sharper,” or more “focused” after adjustments. These sensations align with measurable changes in cortical activity seen in research.
In practice
- We incorporate posture and balance testing as indicators of brain function and attention control.
- Gentle, specific adjustments are performed to improve sensorimotor feedback and cortical regulation.
- We complement care with breathing and body-awareness strategies that support cognitive balance.
