SPINAL ADJUSTMENT DOES IMPACT BRAIN FUNCTION

Updated: Nov 17, 2022

The human body truly is magnificent.

When unhindered by our actions it can heal itself and all areas within communicate perfectly.


But alas daily life, in general, has a negative impact on that balance, so we need to take action to address that.


That is where the remarkable natural therapy of chiropractic comes in.

In terms of mental health, Chiropractic care has been shown to lower blood pressure and can help to decrease other symptoms associated with anxiety and depression.


Obviously, the more at ease a person feels the more impactful their formal mental health treatments are likely to be.

Chiropractic adjustment results in your body increasing hormones such as neurotensin, oxytocin, and cortisol. These help to neutralise stress-induced pain, boosts neuro-communication and boost feelings of social bonding and block pain deriving from inflammation.


Again, an example of how chiropractic allows your body to use its innate ability to heal itself.


We know that spinal function impacts brain function and published research now provides evidence that adjusting the spine changes brain function.


“This is the fourth time that the effect of adjusting the spine has on the brain has been studied and this latest study was confirmed by an independent medical researcher,” [i] enthuses Dr Heidi Haavik, PhD.


Data was collected and analysed by scientists from Aalborg University Hospital in Denmark. None of these scientists was chiropractic driven, thereby lowering any possible bias in this study.





This research shows that spinal adjustment significantly increases the activity in the prefrontal cortex – the area of the brain associated with cognition and higher learning.







An impassioned Dr Haavik states this positive impact on the function of the prefrontal cortex may well explain the documented results of chiropractic adjustment.


Apart from a renewed sense of well-being, many chiropractic patients have also reported increased focus and improved movement and coordination, post-adjustment.


This recent study makes it easier to understand exactly why this positive result occurs.


These are important control mechanisms run by the prefrontal cortex. For example, joint position sense is the brain’s ability to know where the arms and legs are in space.


And mental rotation is important, because as Haavik explains:

The performing of many of our day-to-day skills is controlled by the prefrontal cortex.


It allows us to accurately perceive the world around us. This is necessary for our safety and survival.

This is solid scientific evidence that adjusting the spine changes the way the prefrontal cortex of the brain is processing information from the arm.


It demonstrates we change the way the brain works and shows that spinal function impacts brain function.


If, as this research suggests, spinal adjustment improves prefrontal cortex activity, then what does this mean in terms of chiropractic’s impact on things like behaviour, decision-making, memory and attention, intelligence, processing of pain and emotional response to it, autonomic function, motor control, eye movements and spatial awareness❓


Optimal brain function results in a better-functioning body.


Once again showing the intricate connections within the amazing human body.
