Many people are unfamiliar with the mechanism of the popping sound that occurs during a chiropractic adjustment. 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.”
