Posture as a reflection of brain function
Posture is far more than how we “stand or sit.” It’s a constant, dynamic process involving continuous feedback between the spine, muscles, and brain. Proper alignment depends on how well the brain interprets signals from the body — particularly from the spine’s mechanoreceptors. When spinal segments lose motion, this sensory information becomes distorted, causing subtle shifts in muscle tone, balance, and coordination. Modern chiropractic research, led by Dr Heidi Haavik and colleagues, has revealed how spinal adjustments can influence the neural control of posture through changes in brain processing.
What the research explored
Using tools such as EEG, SEPs (somatosensory evoked potentials), and posturography, researchers examined how spinal adjustments alter sensorimotor integration — the brain’s ability to process and act on sensory feedback. The goal was to determine whether improved spinal function leads to more stable and adaptive postural control.
Key findings
- Spinal adjustments were followed by measurable changes in brain activity linked to balance and postural reflexes.
- Posturographic data showed reduced sway and improved centre-of-pressure control after chiropractic care.
- EEG recordings indicated enhanced activation of cortical areas responsible for motor planning and coordination.
- These changes suggest improved communication between the spinal column, cerebellum, and sensorimotor cortex.
Clinical implications
Posture is ultimately controlled by the nervous system, not just the muscles. Chiropractic adjustments help refine the brain’s awareness of body position, leading to more efficient postural alignment and movement control. Over time, this can translate to better balance, reduced tension, and improved physical confidence.
Our approach
- We assess posture using a combination of visual analysis, balance testing, and movement screens.
- Adjustments are applied to restore spinal motion and optimise sensory input to the brain.
- We complement adjustments with exercises that challenge postural reflexes and stability systems.

This article summarises research on neurological mechanisms of posture control. Chiropractic care is not a “posture treatment,” but improved spinal and neural function often leads to better natural alignment.
