What is that Popping Noise?

What is the Cracking or Popping Noise?

This is a question we are often asked at our Southern Cross Chiropractic offices in the Adelaide CBD & Modbury.
What the practise members are referring to is when they get ADJUSTED, often but not always their is an audible popping noise, read on below to find out how & why it happens!

Simple Analogy

Now imagine I have a water bottle that is 95% full & we tip it on its side, at the top will be a bubble of air, now if I shake the bottle (rapid application of force – the same as an Adjustment) the bubble will break up into lots of small bubbles. Now in our water bottle these bubbles will return to the top & one big bubble very quickly because water has a low viscosity, where as within your joints the fluid is more like honey & thus it takes much longer for the big bubble to reform. It is the change of pressure in the area that causes the he splitting of the big bubble, & when this occurs we hear a POP.

The Science behind it :)

The actual pop is called a cavitation, and it’s the release of gas that makes the popping sound. The joints of the spine are called synovial joints (check out this simple and detailed description here) and they produce a fluid called synovial fluid. Synovial fluid lubricates the joint (for movement) and nourishes it. The byproducts formed in the production of synovial fluid are gasses – oxygen, nitrogen and CO2. When a joint is gapped, or opened up, the gas is released and you hear a distinctive popping sound. It’s very similar to the release of gas bubbles when you cork a champagne bottle, and equally pleasant in its after effects.

Our CBD Chiropractic practise is designed specifically for people who live & work in the Adelaide CBD. Often people who work in the CBD find it hard to get to their Chiropractor because of the open hours. So we thought, hey lets set up a Chiropractic practise in the Heart of the Adelaide CBD so that all of the people working in the CBD can just pop in quickly before work or on their lunch break and get adjusted & feel great.
