The correct name for a sound made during a chiropractic adjustment is a ‘cavitation’. It was once thought that this sound was produced due to a bubble being popped inside the joint, but recently this phenomenon has been recorded via MRI and analysed in depth to show the true cause of a cavitation.

Anatomy - The most common joint in the body is called a synovial joint. A synovial joint has a capsule surrounding it which contains a fluid called synovial fluid, this contains a mixture of fluid and gases which together help protect the joint.
