Preamble: many of these issues are small, yet each issue is just that… an issue. If you take care of the small issues, then the larger issues often take care of themselves and you can focus on the larger issues… a larger, more profitable practice and more family time.

“Cavitation or Audible Upon Adjustment 2”

In doing my research for the Primary Spine Care Conference, I came across this passage that should help clinically every day in practice:

“…and therefore, compared the reflex responses of HVLAT manipulation treatments that resulted in cavitation of the joint, as judged by the treating chiropractor and confirmed by accelerometer measurements with corresponding treatments that did not result in cavitation. They concluded, "the reflex responses seemed to be the same in both cases, which suggests that cavitation was not needed to elicit the observed reflex responses."

 
Simply put, you get the same neurological response with or without the audible “pop” or “crack” as the lay person describes the noise with an adjustment. 

 
This is what happens when you do not read the entire article and comment on just a portion of it… Here is the rest…. (That makes me an ASS!!!! And I am sure Salvaggione will both agree and remind me often)  P.S. I still have 4 more pages to read so there might be more to come

 
When there is an audible “pop” or cavitation, there is demonstrable evidence that neuropeptide substance P is released known as tachykinins. That peptide is known to do many things, one is affect the HPA Axis (Hypothalamus-Pituitary-Adrenal) as well as having a modulatory effect on the terminals of the C-Fibers (nociceptors) and influences the reduction of inflammation. 

 
Therefore, with no cavitation, it affects the neurological response and muscular activity, but with cavitation it affects the neuropeptide substance P release and modulates inflammation.
