Snap, crackle, pop!
Some people associate those sounds with Rice Krispies, but others associate those sounds with chiropractors.
While Dr. Case uses an Activator, which eliminates snaps, crackles and pops, many chiropractors perform more hands-on adjustments, which often results in those familiar sounds.
The actual pop is called a cavitation, and it’s the release of gas that makes the popping sound. The change in pressure releases gas from the joint and creates the sound, which generally feels good for most patients.
Cavitation is exactly the same thing that happens when you crack your knuckles. And ever wonder why some folks call soda ‘pop’? When you open a can, the release of gas POPS!
Wikipedia says, “Cavitation is the formation of vapor bubbles of a flowing liquid in a region where the pressure of the liquid falls below its vapor pressure.”
However, hearing a pop in the chiropractor’s office doesn’t necessarily mean you’ve had a successful adjustment. In fact, in most low force techniques and instrument adjusting techniques, no audible sounds are produced, but successful adjustments are achieved.
Because pops aren’t a conclusive way to determine the success of an adjustment, which is why, patients are analyzed prior to their adjustment as well as afterwards. This is done to determine if the proper correction did or didn’t occur.
