Diversified adjustments are considered the most effective chiropractic corrective technique. It is differentiated from other techniques in that its objective is to restore proper movement and alignment of the spine and joint dysfunction. It is characterized by specific high-velocity, low-amplitude adjustment to correct misalignments and remove interference to the central nervous system.
There is something called synovial fluid present in your joints that acts as a lubricant. The fluid consists of oxygen, nitrogen, and carbon dioxide. When you cavitate a joint, you are stretching the joint capsule. The gasses in the synovial fluid are rapidly released, which creates the popping sound.
