Have you ever wondered what that "pop" sound is during a chiropractic adjustment? It's not your bones cracking or being put back into place. The sound is created when a joint is stretched, causing a rapid change in pressure inside the joint. This allows tiny gas bubbles in the joint's lubricating fluid to form and then rapidly collapse, creating the familiar popping sound.
It's very similar to what happens when you open a can of soda, the sudden change in pressure causes dissolved gas to come out of solution, producing the characteristic fizz.
Contrary to popular belief, the pop isn't what makes the adjustment effective. Some adjustments produce an audible release, while others don't, and both can still help improve joint motion and function. The pop is simply a normal physical phenomenon, not the measure of a successful adjustment!
