Question:
Where does the sound of the "crack" come from when a chiropractor adjusts you?
When you go to a chiropractor, what is exactly making that "crack" sound?
Answers:
Hi Gotham. The crack is thought to be caused by the process called 'joint cavitation'. (Note: this is a theory; researchers have not confirmed this.)
Joint cavitation results from the sudden expansion/release of intra-articular gases (not oxygen) when the joint space enlarges/expands at the moment of the adjustment. This sudden decompression of the joint and expansion of gases creates a 'cavitation' sound (this is similar to the cavitation noises a submarine's screw makes at high rpm's.
Hope this helps you. I am a retired Chiropractor. Best wishes.
