What is that popping sound?
Often, patients hear or feel a “popping” or “cracking” sound during a chiropractic adjustment. Similar to the popping sound of a cork coming out a champagne bottle, the release of pressure on joint during a chiropractic manipulation causes gas dissolved within the joint fluid to come out of solution, form a bubble and create an audible sound.
The adjustment is often characterized by a “popping” sound, called a cavitation, that many people mistake for the “cracking” of bones. The popping sound is actually created by gas (nitrogen, oxygen and carbon dioxide) which is released from the joint as it is moved, similar to the sound made when you remove the top from a bottle of champagne.
