Much discussion has taken place around the noise often heard with an adjustment and there is still a lot of confusion as to what the noise is, what it means, and what is happening. So let's define some language and eliminate some confusion.
Adjustments restore function and stimulate the nerve system. They do not correct the spine's shape, restore curves, or reduce Forward Head Posture (FHP) with any permanency.
An adjustment serves 2 purposes:
1. Stimulates the nerve system- one of the most valuable purposes of an adjustment.
2. Unlocks or mobilizes fixated (improperly moving) joints. (Crucial for maximum effectiveness of a rehabilitation program.)
So what is with the popping or cracking sound that has led to the breakfast cereal confusion? Truth is- we just don't know. There are no studies that I am aware of confirming exactly what causes that noise. There are a couple theories out there but the reality is- it just doesn't matter.
A good adjustment is not dependant on how noisy it is. A good adjustment delivers an outcome (better nerve function and joint mobility). This is measurable and observable in some very practical and simple in office tests.
