The “Popping” Sound What is that “popping” sound? Many people are unfamiliar with the mechanism of the popping sound that occurs during a chiropractic adjustment. Some people are actually scared or nervous thinking that it is causing harm or that it well hurt or it is just “gross”. I have actually had people ask if the bone was breaking. The answer of course is a resounding no! Otherwise I wouldnt have any patients. Here is the mechanism: synovial fluid in your joints contains oxygen, nitrogen and carbon dioxide gases, approximately 80% is carbon dioxide. When a chiropractor adjusts, the joint capsule is rapidly stretched, which in turn increases the volume of the joint by 15-20%. This creates a sudden and rapid partial vacuum which causes the internal joint pressure to decrease. With this decreased pressure the gases rapidly release from the synovial fluid. As they reverberate through the fluid it causes the “popping sound”. For you physic buffs this is Robert Boyles Law from 1662.
