More Than Just Cracking: The Neurological Benefits of Chiropractic Care

This study examines the beneficial effects of a specialized chiropractic treatment known as the Activator Method on individuals suffering from neck pain. The method, which uses a tool to deliver safer, less forceful adjustments compared to traditional manipulation techniques, appears to positively impact the brain’s response to pain and stress.

Using PET scans, the researchers analyzed brain activity before and after the treatment. They observed significant changes, particularly a calming effect in a region of the brain called the cerebellar vermis, which is closely linked to pain perception and automatic body responses. This calming effect appears to be linked to a reduction in pain and a decrease in the activity of the sympathetic nervous system – the part of our “autopilot” that kicks into high gear during stress or physical activity, increasing heart rate, blood pressure and breathing rate.

Additionally, the study highlighted the activation of other brain areas, such as the anterior cingulate cortex and the inferior prefrontal cortex, which appear to play a role in promoting relaxation and facilitating automatic responses that regulate functions such as heart rate, breathing and digestion.

Interestingly, the treatment also led to a noticeable reduction in muscle tension and levels of a stress marker found in saliva that indicates a relaxed state. This suggests that chiropractic care may be able to help reduce symptoms related to stress by promoting a state of relaxation and well-being.

Although this is a preliminary study with a limited number of participants and some subjective feedback, it points to the broader impact of chiropractic treatments, which go beyond spinal adjustments and may influence brain functions in regulating pain and stress.
