What is the crack or popping noise when a joint is manipulated?

“Cavitation” is an audible popping/cracking noise caused from a release of gas. The synovial fluid joint is surrounded by a capsule. When the joint is adjusted or manipulated the carbon dioxide (gas) is released after it has built up. This results in a popping sound. It also cracks when the joint is stretched or realigned.

It can be counterproductive to manipulate your own back or neck as this can lead to over stretching, strain and cause damage to the structures.

Therefore manipulating (cracking) your back is best left to the professional physiotherapist at our Bondi Junction Physiotherapy clinic.
