What causes the noise of an adjustment?
Another example of this phenomenon would be the “pop” you hear when you remove the cork from a champagne bottle. The CO2 in the champagne rushes out of the bottle when the cork is removed. This phenomenon is called “cavitation.” It is this cavitation that is the cause of the noise.
Not all chiropractic adjusting techniques produce the popping noise we associate with “cracking our knuckles.” In fact, some chiropractic adjustments use little force and thus produce no sound. Others may use adjusting instruments, such as the activator technique, and others may use tables.
Is it bad to "crack" your back or neck a lot?
If a person has a desire to pop his neck or back, its usually because a part of his spine is fixated or jammed, causing another part to move too much and pop a lot, sometimes by itself. It’s the jammed or fixated part that must be properly adjusted by a doctor of chiropractic, so that the rest of the spinal column will stop being hyper-mobile and noisy.
