What is the cracking sound?

08 Mar 2016, Posted by Mo Hedayat in

The cracking sound when a joint is adjusted is release of gas pressure in the joint. There is gas dissolved in the fluid inside joints and when the pressure is altered by stretching it, gas bubbles are released. It is the same thing that happens when you open a can of pop.

The purpose of an adjustment is not to make a joint crack but rather to normalize the movement and alignment of the joint. The occasional crack that occurs is more just a side effect of treatment that many patients welcome.
