What’s Really Going On with Subluxations?

You’ve probably heard chiropractors mention the term “subluxation,” but what does it actually mean, and why is it relevant to your health? 

Let’s unpack what’s really happening when this term is used — based on the latest scientific understanding — and how it relates to the way your body functions.

What Is a Subluxation?

In modern chiropractic care, particularly guided by current research, the term subluxation refers to areas in the spine or body where joints aren’t moving as well as they should.

While nothing may be structurally out of place, this lack of proper movement can affect how the brain and nervous system process information from that part of the body.

We know from research, including studies led by neuroscientist Dr. Heidi Haavik, that when spinal joints aren’t moving optimally, it can disrupt the way sensory information travels to the brain. This, in turn, can influence how your brain controls muscles and coordinates movement.

Rather than focusing on bones being ‘out of place,’ chiropractic care today focuses on improving joint function and enhancing the communication between your body and brain.

How Changes in Spinal Function Affect the Nervous System

Your spine does more than provide structure — it plays a vital role in protecting the spinal cord, a key part of your nervous system. Your brain and body are in constant communication, and this system relies on clear, accurate messages travelling back and forth.

When certain joints in your spine aren’t moving well, it can interfere with how the brain receives information from your body — particularly from the muscles and joints. This may affect muscle control, coordination, posture, and even how your brain perceives your body in space (proprioception).

Over time, poor spinal function can contribute to muscle tension, reduced ease of movement, discomfort, or a general feeling of being “off.”

Chiropractic adjustments aim to restore better movement and function in the spine, which may help improve the way your nervous system processes information — supporting better muscle control, balance, and overall function.

What Can Contribute to Spinal Dysfunction or Subluxations?

Many everyday factors can affect how well your spine and nervous system work together, including:

  • Physical stress – Things like slips, falls, prolonged sitting, poor posture, or repetitive movements
  • Chemical stress – Such as poor nutrition, dehydration, or exposure to environmental irritants
  • Emotional stress – Which can create muscle tension and subtle changes in breathing or posture

These stresses can build up and influence how your body moves and how efficiently your nervous system functions. That’s why many people choose regular chiropractic care — not just for pain, but as part of maintaining better movement, posture, and nervous system health.

In Summary

Subluxations, as understood through modern research, are less about bones being ‘out’ and more about how spinal function affects your brain-body connection. 

Chiropractic care focuses on restoring optimal movement and supporting more transparent communication within your nervous system — helping you feel and function at your best.
