That sound during an adjustment. You know the one. It’s called cavitation, and it has a surprisingly simple explanation.
Your joints are filled with synovial fluid that contains dissolved gases, primarily nitrogen and carbon dioxide. Diversified Technique, the most widely practiced chiropractic method in the world, uses a precise, high-velocity, low-amplitude manual thrust to restore motion and alignment to restricted or misaligned joints. That quick, targeted force creates a sudden drop in pressure inside the joint. When pressure drops fast enough, dissolved gases come out of solution, form bubbles, and collapse almost instantly. That’s the pop.
The manual nature of Diversified is what makes cavitation more likely to occur. The speed and specificity of the thrust is what creates the pressure change. But it’s worth noting that the thrust itself is not about generating that sound. It’s about restoring joint mobility and clearing interference in the nervous system. The cavitation is a byproduct of doing that work precisely.
It’s the same mechanism as cracking your knuckles, and research confirms it causes no damage to joints or cartilage.
Here’s the part worth sitting with: the sound is not a measure of success. Many of the most effective adjustments happen in complete silence. A louder pop doesn’t mean it worked better. No pop doesn’t mean nothing happened.
What we’re working toward is restored mobility, reduced tension, and nervous system ease. We’re looking for the place where your system finds the most ease. That’s where the adjustment truly happens, with or without the pop.
